3D Printing

Formify is bringing the power of 3D printing to PC by creating custom mice designed to specifically fit each user’s unique hand shape.

Imagine a mouse that perfectly matches the shape and contour of a user’s hand down to each curve and bend, right out of the box. Formify is looking to make this a real possibility without the need to scan or measure your hands in real-time.

They use a similar process to that of Dr. Scholl’s, a company that creates custom 3D-printed shoe inserts by using photos provided by the user. The company claims that the only thing they need to build a custom mouse is a “palm side up and fingers outstretched” image of the user’s hand.

From there, machine learning algorithms will “analyze the picture of your hand, taking into account factors such as finger length, width, and hand size to identify the optimal design for your performance mouse.”

I've partnered up with @FormifyInc.

It's been a long two years waiting to announce this, Formify creates the perfect mouse shape just from a picture of your hand.

Formify relies on HP’s Multi-Jet Fusion technology to 3D print the mice, a process in which a thin layer of resin powder is fused together using heat to create multiple layers on top of one another. The final design has a slightly rough texture, with users able to choose one of five grips added during the printing process.

In terms of hardware, the custom mice feature Kailh GM 8.0 micro switches under the buttons, a rechargeable battery good for over two weeks of use and a 26,000 DPI optical sensor capable of tracking speeds of 650 inches per second.

The Toronto-based startup has launched a Kickstarter campaign to help bring its products to the market, with around $11,500 CAD raised so far out of the $40,000 goal. Pricing for the mouse is expected to be around $179 (around $240 CAD) after it ships out to backers in December.

Updates on the product will be provided through Kickstarter. As for now, despite being a work-in-progress, Formify’s gamble at combining custom mice and 3D printing looks to be an exciting upcoming project.

The University of Minnesota Twin Cities (UMTC) has created an entirely 3D printed OLED display, similar to those used in modern televisions, monitors and smartphones, using a customized 3D printer.

The new study might pave the way for future OLED displays that could be mass-produced at home using 3D printers rather than by technicians in microfabrication facilities. Published by the peer-reviewed journal Science Advances and published by the American Association for the Advancement of Science, the study might lay the groundwork for future DIY at-home screen repairs.

“OLED displays are usually produced in big, expensive, ultra-clean fabrication facilities,” said Michael McAlpine, the senior author of the study and the University of Minnesota Kuhrmeyer family chair professor, department of Mechanical Engineering. “We wanted to see if we could basically condense all of that down and print an OLED display on our table-top 3D printer, which was custom built.”

OLED panels function by converting electricity into light through the use of an organic material layer. According to the university, they attempted to 3D print an OLED screen in the past to no avail because the uniformity of the light-emitting layers caused issues. This time however, the University of Minnesota team created a six device layer using two different 3D printing techniques, resulting in a “fully 3D-printed, flexible organic light-emitting diode display.”

Some components of the display were extrusion printed, whereas some layers were spray printed, as seen in the video above. The result was a flexible OLED display prototype which is about 1.5 inches on each side and had 64 working pixels.

“I thought I would get something, but maybe not a fully working display,” said Ruitao Su, the first author of the study and a 2020 University of Minnesota mechanical engineering Ph.D. graduate. “But then it turns out all the pixels were working, and I can display the text I designed. My first reaction was ‘It is real!’ I was not able to sleep, the whole night.”

Since the current test display is too small (64 pixels), the university’s next objective is to design a higher resolution display with improved brightness. For reference, a regular 1080p display contains millions of pixels, so the team certainly has a long way to go.

Also, don’t expect to be dishing out OLED displays from home any time soon. The 3D printer used by UMTC is a custom one and costs about the same as a Tesla Model S.
