College of Michigan develops know-how that doubles pace of 3D printing

ANN ARBOR – A brand new software program invented on the College of Michigan that accelerates 3D printing has hit the market.

Developed by spinoff firm Ulendo, the product was just lately launched on the RAPID + TCT Convention — North America’s largest convention for additive manufacturing.

3D printing has lengthy been restricted by its sluggish course of, and U-M affiliate professor of mechanical engineering and founding father of Ulendo, Chinedum Okwudire, stated his software program is altering the 3D printing panorama.

“If you wish to scale back vibration in a shifting object, most occasions you are able to do that by slowing down,” Okwudire stated in a press release. “However as 3D printing is already very sluggish, that resolution creates one other drawback. Our resolution permits you to print quick with out sacrificing high quality.”

He added that the sooner pace wouldn’t essentially imply a bigger consumption of power, which might permit for a possible price discount per printed half.


The Ulendo-developed software program is named FBS, brief for Filtered B Splines — a mathematical operate the U-M staff used to translate the printer’s instructions and vibrations.

“Say you need a 3D printer to journey straight, however attributable to vibration, the movement travels upward,” Okwudire stated in a press release. “The FBS algorithm methods the machine by telling it to observe a path downward, and when it tries to observe that path, it travels straight.”

Okwudire started to design software program in 2011 that might override machine vibrations. In 2017, a graduate scholar from Okwudire’s mechanical engineering lab carried out FBS on a 3D printer.

Ulendo was established by way of U-M’s Innovation Partnerships, and the college has a monetary curiosity within the firm.

It bought off the bottom with a Small Enterprise Innovation Analysis grant from the Nationwide Science Basis and an MTRAC grant from the Michigan Financial Improvement Company.


“Members of the 3D printing trade have the identical jaw-dropping response I had once I first heard about how this know-how ends in a printer working at two occasions the pace and 10 occasions the acceleration,” Ulendo CEO Brenda Jones stated in a press release.
