Extra sturdy prosthetics and medical units for sufferers and stronger elements for airplanes and cars are simply a number of the merchandise that may very well be created by means of a brand new 3D printing expertise invented by a UMass Lowell researcher.
Substances reminiscent of plastics, metals and wax are utilized in 3D printers to make merchandise and elements for bigger gadgets, because the apply has disrupted the prototyping and manufacturing fields. Merchandise created by means of the 3D printing of plastics embody all the pieces from toys to drones. Whereas the worldwide marketplace for 3D plastics printers is estimated at $four billion and rising, challenges stay in making certain the printers create objects which can be produced rapidly, retain their power and precisely mirror the form desired, in response to UMass Lowell’s David Kazmer, a plastics engineering professor who led the analysis mission.
Known as injection printing, the expertise Kazmer pioneered is featured within the educational journal Additive Manufacturing posted on-line final week.
The invention combines parts of 3D printing and injection molding, a way by means of which objects are created by filling mildew cavities with molten supplies. The wedding of the 2 processes will increase the manufacturing price of 3D printing, whereas enhancing the power and properties of the ensuing merchandise. The innovation usually produces objects about thrice sooner than typical 3D printing, which suggests jobs that after took about 9 hours now solely take three, in response to Kazmer, who lives in Georgetown.
“The invention vastly improves the standard of the elements produced, making them absolutely dense with few cracks or voids, so they’re much stronger. For technical functions, that is game-changing. The brand new course of can be cost-effective as a result of it may be utilized in current 3D printers, with solely new software program to program the machine wanted,” Kazmer stated.
The method took about 18 months to develop. Austin Colon of Plymouth, a UMass Lowell Ph.D. candidate in plastics engineering, helped validate the expertise alongside Kazmer, who teaches programs in product design, prototyping and course of management, amongst different subjects. He has filed for a patent on the brand new expertise.
