Printing parts that “work” – the engineer’s desktop

3D Printing brings a whole new dimension to the world of engineers, fabrication and designers. We’ve discussed at length in previous articles the many misconceptions about the world of 3D Printing. In the following article, I’ll focus on the true value of having a 3D Printer in your workflow as an engineer or designer. Just like anything else, a 3D Printer is only one tool among many. But using the right tool for the right job will open new possibilities. It can cut costs, and most significantly, save time.

There’s a lot of hype in the consumer market right now. We all hear of big dreams of a 3D Printer of every home. But currently the technology really shines in prototype development. In particular, this is true for engineers and designers involved in new product development or the redesign of existing products. The ability to get your hands on prototype components, assemblies and complete products and review design issues, improvements and changes is quite simply, invaluable.

The speed of 3D prints

Whether you’re building a tool or fixture, designing a new product, or developing a prototype, as an engineer or designer, you need to fail often and recover quickly. As we know, creating the best possible part design usually requires multiple iterations and redesigns. Previously you would have to wait weeks or even months to see a physical version of your design. But now, 3D Printing has made it possible to get that part created the same day or the next day. This allows creators to print the design quickly, review errors or find improvements, make the changes to the file and print again within a very short time frame.

Today, you can go through 10 iterations in the same time it used 3d-systems-visijet-m3-crystal-mjp-heroto take to complete one using traditional manufacturing methods. Even if that print takes hours or days to complete, you’re still cutting your production cycle down to a fraction of the time spent using traditional methods. Rest assured, there is immense value in turning a design into an object in a timely manner.

 

Complexity is free

This is a phrase you’ll hear thrown around quite a bit in the world of Additive Manufacturing (3D Printing). Traditional manufacturing processes have certain limitations. If you’re using milling or using CNC (Computer Numerical Control) to create a part, you’re removing material from the outside of your block of material and working your way inward. This means any kind of complex internal shape is usually impossible. A CNC machine cannot wrap around corners, but when you’re building from the bottom up, the 3D printer has no problem building organic, complex shapes and structures. If you’re using injection molding, you have to worry about hollow parts, drafting and maintaining wall thickness.

3D Printing doesn’t care about complexity. As long as you’re using some kind of support material system for your part – and using the right material and print method for the job – the complexity of your designs are virtually limitless. Please note that each individual printer will have it’s own limitations you’ll have to work within. However, having access to multiple printer technologies will give you a lot more freedom.

 

MarkForged Printers

Markforged offers a wide range of 3D Printers all specializing in creating parts strong enough for actual everyday use. Developed and manufactured in the United States, these are the only printers on the market that can print parts as strong as aluminum. Their printers generally use two printheads. One builds Nylon parts (or the amazing proprietary Onyx material). The other is a revolutionary new printhead that extrudes composite materials to reinforce the nylon to make solid, strong-as-aluminum 3D Prints. The composite materials used in the machine are Carbon Fibre, Fiberglass and Kevlar, and High-Strength High Temperature Fiberglass.

Mark_x_3D PrinterThe reinforced prints are up to 30 times stronger and 30 times stiffer than ABS 3D-Printed parts. Furthermore, the carbon fibre prints have a higher strength-to-weight ratio than 6061 aluminum. This enables you to create fully functional parts on the printer – rather than pieces prototyped simply for fit before being machined from metal.

Markforged offers a range of options for those looking for more than the standard plastic-jet printers in the ‘prosumer’ price range. Starting at $3499 USD with the Onyx One 3D Printer. Even at its low price point, it has a place in the professional environment. It’s an excellent addition to the Engineer or Designer’s desktop (and totally safe for office use).

The printer ships with everything you need to get started. Including cloud-based Eiger software, giving you full control over customizing your 3D Printed composite fibre model. If you need more materials, you can opt for the Onyx Pro, which has the ability to reinforce with Fiberglass, or the Mark Two, which can print the full range of materials available. Additionally there’s the Mark X, which can print everything the Mark Two can print. However, it has a much larger build size and has a built in scanner to check the part for deficiencies during the print cycle.

Not sure if this printer fits your needs? Give us a call!

If you have any questions, want to see the printers in action, or are looking to order, please don’t hesitate to contact Objex Unlimited 3D Print Studio. You can also read more about the Markforged printers at www.objexunlimited.com

Markforged Announces Onyx – Their most advanced material yet

Markforged announced today the immediate release of Onyx–the most advanced material for Markforged yet–available to all Mark Two Enterprise users. The Onyx material is made up of chopped carbon, and is the first alternative to the base Nylon material. Before all users needed to print with Nylon and reinforce with one of the four fiber materials (Carbon Fiber, Kevlar, Fiberglass, and High-Strength High Temperature Fiberglass). Now users have the choice to print in either Nylon or Onyx and reinforce either with continuous fiber filament (CFF).

The new Nylon material delivers high-performance, finished parts:

  • Embedded carbon enhances performance: Dispersed micro-fibers drive excellent rigidity, dimensional stability, and environmental resistance in parts for rugged use.
  • Cut post-processing out of your process: Onyx parts can be used right off the build plate.
  • Remarkable surface quality: Onyx delivers a stunning matte black finish.

“After hundreds of broken beams and countless reformulations, we’ve created a new material that raises the standard for strength and accuracy,” remarked Markforged’s Chief Scientist Tony Gozdz, “Onyx has more than three times the stiffness of ordinary nylons, and with a heat deflection temperature of 145C, Onyx is perfectly suited for vehicles, machinery, and automation equipment.”

1448-wf-cb133196-b187-4d24-85d4-ca83a3bb38d8-17


Onyx’s dispersed micro-fiber is fully compatible with Markforged’s suite of continuous carbon, Kevlar, and glass fibers – both Onyx nylon and Markforged Standard nylon can achieve part strength comparable with metal.

Here’s what people have been saying:

Revolutionary Material

“Now, all of a sudden, you can get great engineering materials, with the properties that you would want in finished products, and that’s really going to be a game changer,” said Carl Bass, Autodesk Chief Executive (and well-known workshop addict). Mr. Bass was the first person to get his hands on Onyx, and immediately put it to use developing parts for his autonomous go-kart.

Industrial Strength

“The new material from Markforged is a critical component of our design process. This material allows us to turn a prototype into a functional part in hours. While the majority of conventional polymers cannot survive as a production part in our manufacturing environment, this new material is thriving. Markforged has developed a material that takes additive manufacturing one step further,” said Rodney Everett, Automation Technician at Dixon Valve Company, a worldwide leader in couplings and fittings.

Finished Products

“It’s a stiffer material, the edges are true…parts look better and they fit together better. I think we’re going to never look back with this new material… it’s helping us make parts that are direct sale to market,” declared Alan Rencher of Media Blackout, a specialist in customized professional video equipment.

Battle Tested

“This material is fantastic… my team and I are impressed,” said Jamison Go of fighting robot Team SawBlaze. “The dragon head functions as a protective cover and aesthetic. We expect this part to take a lot of abuse, which attests to the confidence we have in this material.”

Team SawBlaze and Team Overhaul, each sporting Onyx and other Markforged reinforced parts in their massive combat robots, will be appearing in televised competition.

Onyx is available on Markforged’s Mark Two Enterprise Kit. The Enterprise Kit includes:

  • A wear-resistant print head that enables the 3D printing of advanced new materials such as Onyx and High-Strength, High-Temperature Fiberglass
  • Software features such as single sign-on, two-factor authentication, and an organizational admin portal
  • Early access to future materials

Printing in Full-colour 3D using ColorJet 3D Printers (CJP)

This article was initially published in the June 2015 Issue of Graphic Arts Magazine.

In this first of several monthly features on 3D printing by Toronto’s Objex Unlimited 3D Print Studio, Brand Manager and Marketing Coordinator Matt Belo explores the fascinating world of 3D ColorJet Printing. These articles are initially written for a Graphics/2D Printing Audience.


ColorJet printing

ColorJet Printing (CJP) is an additive manufacturing process used to create full-colour, photo-realistic 3D models. The range of applications includes concept models, marketing materials, natural models (including humans, animals, geographic/nature images, 3D selfies, etc.), artistic projects and architectural designs, to name a few. These printers are the top choice to print 3D models with stunning realism.

Full Colour 3D Printed Selftrait

Full Colour 3D Printed Selftrait

Colour printing versus full-colour CJP

Many traditional colour 3D Printers operate using multiple print cartridges, each containing a single-colour material. With these printers, the number of cartridges your printer can utilize limits the number of colours in your print. In other words, if you have 5 colour cartridges, your model can contain only 5 different colours. With ColorJet printing, because the colours are mixed in the printer, you can get very complex colouring – including gradients, textures, patterns and skin tones. You can print in full CMYK, giving you millions of colours. The additional benefit is you can apply a ‘texture-map’ to your print, as opposed to breaking your design file into multiple sections and colouring each one manually. Basically, you’re taking a 2D picture and wrapping it around a 3D model. This is the only method to get photo-realistic coloured models.

 

The CJP process

ColorJet Printing Process

ColorJet Printing Process

The ColorJet Printing process involves two primary components: Core™ and Binder material. The Core material can either be a gypsum-based or plastic-based powder. For the first layer, the print bed starts at the highest position in the printer. A roller is used to spread a very thin layer of Core powder across the print bed. Once there is a thin layer powder across the print bed, the printer selectively jets coloured ‘Binder’ material in specific areas where the 3D model is being built to solidify the Core material. The different coloured Binder materials are mixed together to produce millions of colours – in the same way a 2D Printer combines ink. Once the Binder is applied, the process repeats, spreading across a new layer of Core material and using Binder to attach that material to the layer below. After several thousand layers (depending on the size of the model), the end result is a full-colour, three-dimensional model.

 

The finishing process

Due to the nature of the colour printing process, when your print is done you’ll have to extract the finished part from a bed of unused Core material powder. The benefit of this is that the models are self-supporting – the unused core material remains in the print bed supporting any overhangs within your print,

eliminating the need for any support material. In their unfinished state, the models are extremely fragile, therefore you must extract the part from the powder very carefully. Once you have extracted your part, you use air to blow away excess core material (which gets recycled back into the machine), sand your part to get a smooth finish, and then dip it in cyanoacrylate (superglue) to make it stronger.

 

File preparation

Your file needs to follow the general rules of a “Print-ready” 3D file. This means it needs to be completely closed (or watertight) and each of its edges needs to be shared with two polygons. Additionally, with ColorJet printing, it needs to be a certain thickness so that the model can actually support itself in the printer. To save on material costs, ColorJet models are generally hollowed. Most 3D printers use “.stl” files, but with CJP, you need to provide a colour 3D file – generally a .zpr or .wrl file. Anything else must be converted, along with a texture map file (usually .jpeg or other 2D formats) that contains all the complex colour data that will be applied to the 3D model. There is a bit of a learning curve to preparing these files, so I recommended you contact a ColorJet Printer operator to give you advice on preparing your files. Objex Unlimited is happy to share this type of information. Not to toot our own horn, but Objex Unlimited is known for producing some of the best colour models in the world.

3D Systems ProJet 660Pro

ProJet 660Pro

While there are a range of 3D Printers in the ColorJet Printer line, the 660Pro is one of the printers that includes many key features – full CMYK colour, attached model finishing chamber, a faster-than-average print speed, and a larger-sized print bed. It’s also quite affordable when compared to other professional-level 3D printers. However, there is a full range of ColorJet Printers that make up the ProJet x60 series, from the more budget-friendly ProJet 260C, to the large-build area of the ProJet 860Pro. They also have the ProJet 4500, which can print CMY plastic powder, for a more robust model when accurate colour is less of a concern.

Art by Oliver Pauk brought to life with 3D Design and Printing

Here’s another great example of using 3D Design and 3D Print to turn imagination into real life!

Not long ago, an artist by the name of Oliver Pauk visited a 3D Printing talk by Steve Cory, President of Objex Unlimited. He started asking questions and eventually visited the offices here to see the different printers on-site, and started to realize how the different technologies could help him develop his art. The piece eventually created was part of Oliver Pauk’s Objects collection, which can be seen here: www.oliverpauk.com/objects/.

Oliver Pauk - Objects Collection

Oliver Pauk – Objects Collection

 

Oliver Pauk was experienced creating 3D Designs in photoshop and wanted to make his file printable. It was determined that the best technology for the job was Stereolithography (SLA) 3D Printing, which uses a laser and a plastic based liquid resin, optimal for extremely fine detail at a comparably high strength. As SLA is not a colour printing technology, the colours were applied to the model using Hydrodipping. The process involves taking a non-porous plastic, placing a coloured film across a the surface of a vat of water, and then dipping the object into the vat as the colour transfer wraps around the object.

The results are absolutely amazing!

ProJet 1200 Expands their Suite with New Materials and Applications

3D Systems has announced the expansion of its ProJet® 1200 suite with the arrival of five new materials engineered specifically for the desktop printing capabilities of its micro-SLA 3D printer. These five new materials join the previously introduced VisiJet® FTX Green material, expanding the capabilities of jewelers, dental labs, manufacturers, engineers, and 3D artists in the creation of casting patterns, small end-use parts, figurines and presentation models.

ProJet 1200 – Jewelry

Advancing the production capabilities and throughput of jewelry designers, the ProJet 1200 now has an advanced FTX Cast material, a wax/resin hybrid material developed specifically for compatibility with a wide range of jewelry casting methods and materials, and FTX Gold and FTX Silver for stunning jewelry samples and presentation models.

1200 Gold Silver

Jewelers can easily integrate FTX Cast, which casts much like traditional wax, into existing workflows with the added benefits of 3D printed parts.  Combined with the precision and fantastic surface quality of micro-SLA from the ProJet1200, FTX Cast can be used to create exquisite, detailed pieces from rings to pendants. With glimmering gold and silver particles embedded in the materials, FTX Gold and FTX Silver provide the wow factor that brings customer presentation models and counter samples to life.

ProJet 1200 – Dental

Dental labs use the ProJet 1200 with FTX Green for the production of highly accurate, casting-friendly wax-ups for a range of small dental prosthetics. The ProJet 1200 prints in 30-micron layers at 585 dpi resolution for the production of up to 12 high-quality wax-ups in an hour, right on the desktop. The ProJet 1200 and FTX Green combine for an accelerated workflow with the exceptional results of traditional methods.

ProJet 1200 – Engineering and Manufacturing

Along with the casting capabilities of FTX Cast, engineering and manufacturing customers can take advantage of the arrival of FTX Gray, a high-contrast gray material that’s perfect for prototypes and accentuating fine features, and FTX Clear, a transparent clear material that can be applied in end-use parts and components. As part of the reimagined engineer’s desktop, the ProJet 1200 and FTX Gray and Clear allow engineers a fast way to locally create precise design prototypes of small assembly or components. Micro-SLA parts in FTX Gray and Clear also combine the strength and precision necessary for end-use applications and final one-off custom components, such as electronic connectors, robotics components and more.

ProJet 1200 - 6 Materials

 

ProJet 1200 – 3D Artists and Designers

Many 3D artists, designers and professional model makers also require strong, precise micro parts for toys, figurines, model aircraft, cars, model trains and more. The expanded ProJet 1200 materials selection provides even more opportunity for creative expression. Precision FTX Gray parts are paintable and they accentuate the fine features for which the ProJet 1200 is known. On top of that, beautiful, transparent FTX Clear parts project a hint of iridescence for stunning clear parts, perfect for a range of sculptures and model components. For artisans creating small cast sculptures, FTX Cast provides a less work intensive way to make accurate casting patterns in the workshop.

“The addition of these five materials represents our commitment to revolutionizing desktop 3D printing and bringing new capabilities to dental techs, jewelers, artists and engineers,” said Buddy Byrum, Vice President of Product and Channel Management, 3DS. “Now a jeweler, for instance, can design a ring, prototype it in FTX Gray, print a customer sample ring in FTX Gold and FTX Silver, and create a final casting pattern in FTX Cast—all from the same machine.”

The expanded VisiJet FTX material range will be available in December 2014 and will be on display at EuroMold 2014 in Frankfurt, Germany from November 25-28, 2014, at the Messe Frankfurt in booths D69 and F90 in hall 11, along with 3DS’ latest 3D printers, advanced material options, cloud-sourced custom parts and digital thread of 3D capture, creation, print and inspection tools.

iReviews names Artec Eva the best 3D scanner under $50,000

Blog originally posted on www.artec3d.com/news.

See the iReview review here: www.3d-scanners.ireviews.com/artec-eva-review

Scoring five stars for value, design, experience and price, the Artec Eva bagged Gold in the iReviews 2015 nomination for the best 3D scanner under $50,000.

The Artec Eva is a versatile 3D scanner that is handheld, which means that it is not bound by the restrictions of a tripod or stand mounted system. A wide variety of things can be scanned, including the human body, which broadens the applications significantly. With the ability to accurately and quickly scan people, we suddenly have a way to provide accurate and properly-fitting prosthetics, as well as support devices. We can also insert the scanned data into other images, creating decent quality special effects for movies and other entertainment media. It also opens up a world of possibilities in the research fields, which helps make the world a better place.
The handheld design makes the Artec Eva feel a lot like a video camera when used. An ergonomic handle keeps the process comfortable as well, which is important when scanning large objects that can take more than a few minutes to capture. The Eva captures up to 16 frames per second, automatically aligned by their powerful software package as you go, which makes scanning not only fast but accurate. This is critical in fields where not only speed but accuracy is important, especially when the scans are for forensic investigations, medical research or CGI animation. This can potentially save a life, prove someone’s innocence and even improve the quality of life for millions of people.The Artec Group, based in Luxembourg, is a company dedicated to designing and manufacturing innovative products. The team is composed of people who have worked together for over 10 years and who are experts in the fields of 3D image capturing and face recognition. They also have offices in Palo Alto, CA and in Moscow, Russia. Contact info for each office is provided on their website, as well as a form you can fill out to request a demo of any of their products.The Artec Eva is very easy to use. Simply press the button on the unit and begin scanning an object by moving the scanner around. There is no worry about doing something wrong. There are both audio and visual cues that guide you through the process should you need it. This alone helps reduce the learning curve significantly, making the odds of producing a top-quality scan on your first attempt increase significantly. Whatever you don’t pick up on the first pass you can return to and re-scan missed areas. Once the scan is done, the software goes to work. It aligns the scans, fuses them into a 3D model, and then allows you to smooth and optimize the data to fill in holes, increase definition, etc. If you have purchased texturing capabilities, you can apply texture to the scan as well. Once you are done, you can save the data in any number of compatible 3D file formats for export, which can accommodate a wide range of 3D applications.Overall, we found the Artec Eva to be innovative, affordable for a scanner in its class and very easy to use, producing top quality results without having to be an expert in 3D scanning and telemetry. With all the wonderful features included in this package, we are glad to award the Artec Eva the top spot on our list of iReviews 2015 best 3D scanners under $50,000. 

Price: $19,800

 

Pros:


1. Best overall value of any scanner in its class
2. Supports a wide range of file types
3. Long range scanning up to 1 meter
Cons:


1. Texture capture upgrade is expensive
2. Software not included in the price

3D Printed HMS Erebus bell replica, scanned using Artec Eva, to be centrepiece of Franklin Expedition exhibit

Last week, the ROM announced their new exhibit outlining Sir John Franklin’s lost 1845 expedition to find passage in the Arctic Northwest. The centrepiece of the exhibit? A full-scale, 3D printed replica of the bell that once rung aboard the HMS Erebus.

 

PARKS CANADA - Recovery of the bell of the HMS Erebus

 

The replica of John Franklin’s bell was created using an Artec Eva 3D Scanner and a 3D Systems ProJet 660Pro. First, the 3D scan was actually done underwater to ensure that the bell kept it’s original shape and was not damaged during the extraction. The Artec Eva has the advantage of being one of the most flexible scanners on the market today, and has the ability to capture both colour and geometry simultaneously. Second, the replica was printed on a ProJet 660Pro, 3D Systems’ full colour printer (and one we use every day here at Objex Unlimited), due to its amazing colour reproduction and photo realistic printing abilities. When it comes to realism, there really is no other 3D Printer that can reproduce colours like the 3D Systems x60 Series.

 

 

From the National Post: “The bell that was recovered from the ship requires extensive conservation and so the creation of a full-size 3D replica — the only one in the world — seems to us to be a great way to launch this project,” said Janet Carding, the museum’s director and CEO.”

 

There are certainly no shortage of examples where 3D scanning and 3D printing have been used in conjunction to restore historically significant items and artifacts that would otherwise be too fragile or delicate for public display. Every day, more and more museums are turning to 3D printing as a means to create perfect replicas of existing artifacts, or restoring artifacts that have already been damaged.

Hershey to Launch the First Ever 3D Printed Chocolate Exhibit

Originally posted on 3dprint.com by Brian Krassenstein

When it comes to the 3D printing of food, probably the most popular, easiest, and most delectable food to print with is chocolate. We’ve seen numerous companies, both large and small, experiment with the process, and in fact there are several chocolate printers in production as we speak, which are capable of intricate fabrication of unique chocolate objects.

Out of all the companies out there, one instantly pops into most individual’s heads when they think of creamy, rich chocolate, and that is Hershey. With the history, the market reach, and the drive within the company, it was only a matter of time before the Hershey, Pennsylvania-based chocolate producer would integrate 3D printing into its operations in some way, shape, or form. Today is that day!

Teaming up with 3D Systems, Hershey has announced that on December 19th they will debut the 3D Chocolate Candy Printing Exhibit at the Hershey’s Chocolate World Attraction. Here, visitors will have the opportunity to watch and interact with scientists at the company as well as 3D printers spewing out the rich creamy candy.c2

“We are now using 3-D technology to bring Hershey goodness to consumers in unanticipated and exciting ways,” said Will Papa, Chief Research and Development Officer, The Hershey Company. “3-D printing gives consumers nearly endless possibilities for personalizing their chocolate, and our exhibit will be their first chance to see 3-D chocolate candy printing in action.”

Hershey will use the feedback and insight gathered from visitors at the attraction to gauge their entrance into the space, with ultimate plans to utilize 3D printing to create an experience, and possibly products, like none other. The visitors will actually be the ones who, perhaps unknowingly, shape the future of commercial chocolate 3D printing.

“We are committed to democratizing 3-D printing, making this game-changing technology accessible and engaging for everyone,” said Chuck Hull, Founder and Chief Technology Officer, 3D Systems. “Our partnership with Hershey, the largest producer of quality chocolate in North America and a global leader in chocolate and confections, allows us to create unique, exciting and personalized edible experiences, and this is a great way to showcase the power and possibilities of 3-D printing.”

The 3D Chocolate Candy Printing Exhibit will allow visitors to get scanned and then be transformed into a chocolate-looking sculpture on screen. They will also have the opportunity to watch live as one of the most advanced chocolate printers in existence works its magic.

If you happen to be in the area and want to stop in, Friday of this week will be the grand opening of the 3D printing exhibit. The address of Hershey’s Chocolate world is 251 Park Boulevard, Hershey, PA. Let us know if you have the opportunity to stop in. Take some pictures and document your experience in the Hershey 3D Printed Chocolate Exhibit forum thread on 3DPB.com. Check out the promo video below:

3D Printing: Dog’s Best Friend

Derby the dog was born with a congenital disease that caused a malformation in his front paws. More like flippers than feet, Derby’s condition made it difficult for him to get around, but true to the effervescent spirit of a puppy, Derby demonstrated heart-breaking determination to move and play. Though he managed decently enough in soft, indoor environments, hard outdoor surfaces were out of the question. So how is it that Derby can now run and frolic with abandon?  Why, with his custom-3D printed prosthetics, of course!

Tara Anderson is an animal-lover with a record of dog rescue. She counts two rescue dogs as permanent family members, and has fostered countless others. When Tara heard of Derby’s struggle for mobility and need for a family, Derby had her heartstrings in a knot. She volunteered to foster Derby through Peace & Paws, a rescue center in Hillsborough, NH, and worked with them to outfit Derby with a wheel cart to help him get from place to place. “It was a good solution for him to move in straight lines, but overall it wasn’t super maneuverable, and he still couldn’t play with the other dogs or play fetch like he wanted to,” Tara said. “We needed something better.”

Tara was struck with inspiration. As an employee of 3D Systems, she knew the capability of 3D printing technology and decided to ask experts at the office if they would help. After a resounding yes, Tara also enlisted the help of Derrick Campana, an expert dog orthotist at Animal Ortho Care in Chantilly, VA.

Derrick and the 3DS team worked together to create a workable design. They created cups to hold Derby’s front legs, first manually with carved plaster casts and then digitally, with the Geomagic Capture 3D scanner. The 3D contour model was imported into Geomagic Freeform to design the prosthetic legs and then digitally matched up with CT scan data of Derby’s anatomy. By the time this had all been orchestrated, Derby had transferred to fully adoptive owners who were invested in the project and keen to see if prosthetics would work.

Disappointingly, the first ‘peg leg’ design was a disaster. “Derby didn’t understand them and had trouble balancing on them,” Tara said. “They didn’t reflect the kind of flexibility of motion he needed, so it was back to the drawing board.”

As Director of ColorJet Printing (CJP) Product Management at 3D Systems, Tara has a strong background in 3d printing as well as in architecture, and after the first failed testing of Derby’s prototype prosthetics, she went home and started a new product design. “I could tell from watching him struggle that he would be better served by a different design, and it occurred to me that a spoke-and-rocker design would reflect and respond to Derby’s developed method of getting around.” Once she had the idea, Tara went home and sketched it up.

She took her newly conceived design to her colleague at 3DS the next morning, and a few days later the new prosthetics were printed on the ProJet 5500X, a multi-material 3D printer from 3D Systems.

“They were an immediate success,” Tara said. “As soon we fitted them on Derby, he took off running. It was incredible. I can’t describe how gratifying it was to see him finally get to move like he’d always wanted to.”

Derby’s adoptive owners, Sherri and Dom Portanova had the same reaction.

“I’m not easy to impress, but these legs got me. Derby was immediately on the move and now he runs 2 to 3 miles daily, usually faster than my wife and me. It’s amazing.”

Though the second round of prosthetics was a success, further iterations are still being tested with a higher ratio of rubber materials for better grip and comfort.

“That’s the beauty of 3D printing,” Tara said. “We don’t have to wait for tooling, we can just adjust the design and reprint it for use. From my perspective, Derby’s case is what 3D printing is all about. We’re taking a critical need, developing ideas for a solution, and taking advantage of what 3D printing has to offer to make those ideas happen. It’s changing the world, one paw at a time.”
