MIT’s OpenFab Could Revolutionize 3D Printing Design Process
MIT Researches Use CGI Techniques to Simplify 3D Printing
A group of researchers at MIT are taking a page from the movie business to revolutionize 3D printing. They have developed an architecture pipeline, called OpenFab, that aims to dramatically reduce the learning curve and barriers involved in designing for 3D printing.
“Our goal is to make 3D printing much easier and less computationally complex,” said Associate Professor Wojciech Matusik, co-author of the papers and a leader of the Computer Graphics Group at CSAIL, in an interview with MITnews. “Ours is the first work that unifies design, development and implementation into one seamless process, making it possible to easily translate an object from a set of specifications into a fully operational 3D print.”
With the state of 3D printing today, it’s relatively easy to press print when you have a finished 3D model, but it’s quite a challenge to create a design from scratch that can be 3D printed. OpenFab hopes to change that.
Here is the abstract from the paper published by MIT researchers. Full details available at the OpenFab website.
3D printing hardware is rapidly scaling up to output continuous mixtures of multiple materials at increasing resolution over ever larger print volumes. This poses an enormous computational challenge: large high-resolution prints comprise trillions of voxels and petabytes of data and simply modeling and describing the input with spatially varying material mixtures at this scale is challenging. Existing 3D printing software is insufficient; in particular, most software is designed to support only a few million primitives, with discrete material choices per object.
We present OpenFab, a programmable pipeline for synthesis of multi-material 3D printed objects that is inspired by RenderMan and modern GPU pipelines. The pipeline supports procedural evaluation of geometric detail and material composition, using shader-like fablets, allowing models to be specified easily and efficiently. We describe a streaming architecture for OpenFab; only a small fraction of the final volume is stored in memory and output is fed to the printer with little startup delay. We demonstrate it on a variety of multi-material objects.
Simulation-Based Design for 3D Printing: Special Effects and the Store of the Future
In a two-part lecture during the Inside 3D Printing conference in Chicago, artist and designer Isaac Katz of Electronic Art Boutique gave us an overview of the powerful 3D modeling software programs available on the market today. He considers these programs to be essential creative tools, which he uses to create works of art, jewelry and sculpture in a process he calls “simulation-based design“.
Katz employs sculpting programs like Zbrush and Mudbox, and the more CAD-centered Rhino to create powerful and detailed images which he projects onto canvas, and exports to 3D printers to create sculptures and jewelry casts. These tools are commonly to create visual effects for 2D media, but can have a broad range of other applications, including architecture, industrial design, jewelry, sculpture and others. Katz emphasized that programs like Zbrush and Mudbox harness a great deal of mathematical power, and are capable of generating an “incredibly high level of detail” that extends even beyond what current 3D printers are capable of rendering in a physical model.
However, Katz noted, 3D printing capability continues to catch up and is poised to grow exponentially, and the intersection of 3D simulation technology and 3D printing has the power to change our visual experience of the world.
For designers, Katz explained that this process presents a completely new way of looking at design and product creation that allows them to both capture more detail and project a range of organic and fluid shapes that may otherwise be difficult or impossible to obtain. Increasingly, if you can imagine and create a character, you can animate and print that same character using motion capture technology, as well as other non-traditional, non-CAD software, and thanks to 3D printing technology, you can also create a physical model of your character.
For investors and business owners, the combination of simulation technology and 3D printing provides “a glimpse into the design process…and some vision for what’s possible,” both today and in the years to come.
In the second part of his lecture, Katz articulated his vision for the future of retail in a world that continues to trend toward greater personalization. Katz drew a sharp contrast between the retail store of the present, in which producers and customers alike are forced to transact around pre-designed and pre-fabricated products, and the store of the future, in which customers will be able to purchase clothing and other goods that are uniquely made to their specifications at or after the time of purchase.
Such a world, in Katz’s view, would not only allow retailers to save costs by eliminating the need for complex distribution chains, but it would also invite users into the creative process as part of the retail experience.

SupplyBetter Launches 3D Printing Comparison Engine to Give Designers More Choice
SupplyBetter Launches Comparison Shopping for 3D Printing
Calling itself the “Kayak of 3D Printing”, SupplyBetter provides comparison shopping for 3D printing. With over 200 suppliers, SupplyBetter gives more choice to a designer or consumer looking for a 3D printed object. Sometimes you want to print high quality and sometimes you want low cost. SupplyBetter helps you find the right fit.
We spoke with SupplyBetter co-founder and CEO Matthew Du Pont.
On 3D Printing: Tell us what SupplyBetter does.
Matthew Du Pont: SupplyBetter does two main things.
1) We help buyers find better service bureaus for 3D printing – most companies online are trying to sell you their own printing services, even if they’re not the best fit. We have a database of hundreds of companies that provide 3D printing, which lets us match companies with the right supplier based on geography, material, price, speed, and application. It’s similar to Kayak – buyers come to us, upload a drawing and some information on what they want, and we pick the best suppliers and pull together quotes for the buyer.
2) We help buyers find better contract manufacturing beyond 3D printing. Our eventual goal is to be the best way of finding manufacturers for custom mechanical parts, so whether they need a small run of wood parts in the US or metal casting in China, we’re happy to help them out. We charge buyers if and only if they select a supplier we find for them, and have helped people with wood, plastic, and metal parts.
On 3D Printing: How did you get started?
Matthew Du Pont: Matt and Rob have been friends for seven years. They both have previous unpleasant experiences with procuring custom parts (Matt at a trucking company, Rob at a robotics company), and decided to build a better way to get things made. They’ve been working on SupplyBetter since early 2013.
SupplyBetter has helped buyers in North America and Europe, and quoted suppliers worldwide. Our customers so far have mainly been hardware startups and makers, seeking to prototype or bring prototypes to production.
On 3D Printing: Where can someone go to learn more?

3D Printed Lightclip Lets You Signal Batman With Your iPhone and More
3D Printed Lightclip Turns Your iPhone into a Batman Signal, or a Ninja Ghost, and More
This is a review of Lightclip, one of the coolest and most elegantly-designed 3D printed products we’ve come across. We also interview the designer.
(For full disclosure, the designers behind Lightclip sent us a complimentary product to try out.)
The Lightclip is a 3D printed accessory for the iPhone that becomes illuminated when you turn on a flashlight app. A variety of designs were created by Lab02 and are available for sale at Shapeways for $12 to $17 each.
Our Impression of Lightclip
The design is quite a step up from what you would normally expect from 3D printing. Instead of rigid ABS plastic, the Lightclips are 3D printed in White Strong and Flexible (Nylon). As Shapeways said in their own review:
This material is very strong (obviously), affordable and an excellent light diffuser. The Lightclip emits a beautiful ambient light, which is evenly distributed and very easy on the eyes. Use it as a nightlight, at a camping trip or when in need of a superhero!
We loved the different types of Lightclips. Included in the Shapeways store are a traditional light bulb, a ghost, a ninja ghost, and a Batman spotlight. Each one fit perfectly to capture all of the light from the iPhone flash; no leakage. See the gallery below for examples.
Fun for kids. Though not a toy, kids were very attracted to the Lightclip, turning the flashlight on and off repeatedly to see the Lightclip glow.
In summary, the Lightclip is really more about fun and fashion than function, but it’s worth the $15 price point as a conversation piece and perhaps a night light on occasion.
Interview with the Designer of Lightclip
We interviewed Dinos Costanti, the designer of Lightclip. The transcript of our interview is below.
On 3D Printing: Tell us about your organization and your history in 3D printing.
Costanti: My name is Dinos Costanti and i’m a software developer and 3D modeler. Vangelis Hadjiloizou is a painter and the ex Creative Director of the largest advertising agency in Cyprus. We started working together as freelance industrial designers in 2011. Right from the beginning we wanted a way to prototype our designs. We had access to a nice CNC machine locally, but we needed something better. That’s how we started using Shapeways and i.materialise.
We were very impressed with the capabilities of the modern 3D printers, especially with the EOS SLS machines. We even used them for a small production run of 110 small mushrooms that we designed as a giveaway for one of our customers. That was the final proof for us that 3D printers can be used for small scale manufacturing.
So we launched Lab02.org as a place to show and promote our personal designs. That is probably the dream of every designer; A way to make and sell the products that no one is willing to fund and manufacture! And as 3D printing becomes more popular, we’d love to feature the designs of other Cypriot designers.
Over the past 3 years we’ve gained a lot from the 3D printing community. And it is thanks to it that we can now afford our own 3D printer. As our way of giving something back we’ve made the Lightclip available under a Creative Commons license. This way anyone can download, modify, and print his or her own for free!
On 3D Printing: The designs you have made are very intricate and probably more elegant than what most people would expect when they think of 3D printing. Was it difficult to design?
Costanti: Not at all! The Lightclip went from initial idea to sketching, modeling and prototyping in about 10 working days. That included 5 days for Shapeways to print and ship the prototype.
I think that the 3D design software companies are starting to realize the need to address the amateur or rather the non-engineering crowd. We mainly use Moi3D, a NURBS modeler created by Michael Gibson, the original developer of Rhino. This is probably the easiest and friendliest NURBS modeler on the market and a perfect fit for designing for 3D printing.
On 3D Printing: How do you see these types of 3D printed goods growing in adoption?
Costanti: The production of 3D printed goods is going to explode. As more 3D printers are becoming available, prices are being pushed down. And as 3D printing materials become cheaper we are coming to a point, maybe in a year or so, where 3D printing will be a viable and cost effective solution for small scale manufacturing. Especially so for the 100 – 3000 units production runs which, using traditional injection molding, are currently in kind of a “no man’s land”. That is mainly due to high molding costs which demand a major investment with traditional methods, but are not required at all with 3D printing.
That is going to have a profound impact on the variety and complexity of available products as more and more designers can simply self-publish their products using their own 3D printer or a 3D printing service.
On 3D Printing: How has your experience with Shapeways been?
Costanti: Our experience with Shapeways has been amazing right from the beginning. Their engineers are very knowledgeable and they were instrumental in our quest to master the basics of designing for 3D printing. Also, their printing times are constantly improving. They will usually ship a lot sooner than the date they quote!
There is little doubt in my mind that these 3D printing services are the prototypes for the factories of the future.
On 3D Printing: Any other creative ideas your working on at the moment?
Costanti: We’ve had another very successful product with i.materialise, the Dragonbite grip which was designed for printing in stainless steel. It is currently the feature of a design competition at i.materialise.
We are also working on the initial sketches of our new project, a water pipe, designed to be printed in ceramic. This is the one material we haven’t used so far and we are very excited about it. I’m sure that it will present its own challenges but it is something we wanted to try for a long time. We hope it will be available in a month or so.
Thanks for sharing the Lightclip with us!
Tinkercad Acquired by Autodesk: Free 3D Design Software Lives On!
Tinkercad Acquired by Autodesk
In what will be great news to Tinkercad fans across the globe, the free 3D design software has found a new home at Autodesk. Autodesk has a suite of pro design software and its own free software such as 123D and 123D Catch for iPad.
Tinkercad is free, online 3D design software that is popular among 3D printing enthusiasts. The team announced they were shutting down Tinkercad in March 2013.
Now, in a change of course, Autodesk has acquired the software and website.
Here’s the memo from Founder & CEO Kai Backman:
I am happy to announce that we have just signed a deal where Autodesk will purchase the Tinkercad site and core technologies. This is a great day for all Tinkercad users, Autodesk is an very enthusiastic and capable steward. There are two main impacts of this deal: the site is fully operational and Autodesk has some very exciting plans for Tinkercad.
The shutdown plan has been rolled back and effective immediately new users are again able to sign up for the site. Even better, at the request of Autodesk, we have supercharged the free plan. You can now create unlimited designs, all import and export functionality is enabled and ShapeScripts are turned on for free accounts. We have automatically upgraded all existing free accounts to this new powerful plan. This account will be offered for a limited time only so make sure you sign up as soon as possible.
Before signing the deal the we spent a lot of time talking to Autodesk engineers and product people about their vision for Tinkercad. We were impressed by the deep insight the Autodesk team had into the Tinkercad interface and the underlying technology. There is also a strong alignment on topics like furthering education and the vision of making design more accessible. But most of all we are very excited about the roadmap Autodesk has drafted for Tinkercad.
As our team continues working on Airstone I’m pleased to see Tinkercad find a safe and welcoming home. I can speak for everyone when I say that we are looking forward to using Tinkercad for a long time to come.
Yours sincerely,
Kai Backman
Founder & CEO
