Steve Schell, a Caltech grad with strong ties to Idealab in Pasadena, California, felt strongly that the widespread adoption of 3D printers as a form of creative expression would require a major advancement in ease-of-use.

We met up with Steve Schell at a 3D printing conference in Burbank in late January, 2014 just after Idealab had funded his company, known at that time as IdeaShaper. Over lunch, Steve talked about his plan for creating not just a 3D printer, but an end-to-end solution for creative expression. He explained that the 3D printer would be affordable, would connect wirelessly to an online library of 3D files, and would come with user friendly software. It would be simple enough for anyone to use, even those with limited computer expertise. Steve wanted a 3D printer for ordinary folks, not just those immersed in hackerspace. If successful, the effort would create an entire community of users sharing 3D content and encouraging each other to explore creative expression. The online library would provide ordinary people with a place to share or sell their creative work. Interestingly, New Matter would later come to name the printer the MOD-t giving a nod to Henry Ford’s invention that democratized automotive technology.

We Were Intrigued

And so we began to follow the development effort with great interest. Early on, we learned that quiet printer operation would be important for successful home use. Imagine a noisy dishwasher running for 16-20 hours a day and you get the idea. Initially, the MOD-t used industry standard stepper motor drives common to most entry level 3D printers. With our expertise in inkjet printer development we recognized that DC servo motors could not only provide a quiet motion solution, but if implemented properly, could also improve dimensional accuracy during the build.
We presented a comparison of stepper motor technology to DC servo motor technology. While the development work would be more intensive for the DC servo motor solution the benefits were clear for this application.

There are a lot of great 3D printers on the market, but most of them are either a. out of my price range (i.e the Formlabs Form 1), b. Loud and difficult to maintain (i.e RepRap) or c. both. Today I came across a printer that's neither. It's not perfect, but it's pretty damn great.

One of the great things about Simplexity is that their expertise is fairly wide ranging throughout the product development process. Their focus on the MOD-t project with New Matter was the embedded motion control system, the electronics design for the controller, and testing of that system as a whole. 

It's great to have a partner like Simplexity who has so much expertise in the electro-mechanical systems as well as the embedded software because it bring so much capability to my engineering team in those really critical technology areas.

Seamless integration

The next step was to figure out how Simplexity-developed motion control solutions could be integrated into New Matter’s development effort. Simplexity proposed a firmware architecture that would allow New Matter to focus on higher level programming tasks leaving the low-level motion control to us.

The CRICKET lABS MECHATRONICS Board

On the hardware side, New Matter wanted a single PCA to minimize cost and complexity. Simplexity developed the MOD-t main controller board by optimizing Cricket Labs' motion control PCA. Simplexity had previously developed Cricket Labs' motion control PCA as a general purpose platform intended to be licensed and used for mechatronics applications.  It allows for a faster time-to-market since it serves as both a development platform and a reference design that is easily customized to new applications. By applying this technology to the MOD-t printer, Simplexity was able to reduce both development time and risk for New Matter.

As a development board, Cricket Labs' motion control PCA provides general purpose two-axes motor control, numerous analog and digital I/O sensor interfaces, and a powerful ARM 32-bit Cortex-M processor. Development boards can be joined for applications involving more than two motion axes.

Simplexity developed the MOD-t main controller board by optimizing our SNAP motion system controller.
New Matter and Simplexity developed a technically superior, 3D printer with quiet motion technology for under $400.

Impressive Results

The results are impressive. Working together, New Matter and Simplexity developed a technically superior 3D printer with quiet motion technology for under $400.
