Abstract:
More durable prosthetics and medical devices for patients and stronger parts for airplanes and automobiles are just some of the products that could be created through a new 3D printing technology invented by a UMass Lowell researcher.

New printing process advances 3D capabilities: Technology aims to improve quality of products used in business, industry and at home

Lowell, MA | Posted on July 31st, 2020

如塑料,金属和蜡物质在三维打印机用于制作产品和部件对于较大的物品,如实践已经破坏了原型和制造领域。通过塑料的3D打印创造出来的产品涵盖了从玩具到无人机。虽然3D塑料打印机全球市场预计以$ 120元十亿和增长,仍然存在挑战,确保打印机创建迅速生产出来的物品,保持其强度和准确地反映所需的形状,根据麻省大学洛厄尔的大卫Kazmer,塑料工程教授谁领导的研究项目。

Called injection printing, the technology Kazmer pioneered is featured in the academic journal Additive Manufacturing posted online last week.

The invention combines elements of 3D printing and injection molding, a technique through which objects are created by filling mold cavities with molten materials. The marriage of the two processes increases the production rate of 3D printing, while enhancing the strength and properties of the resulting products. The innovation typically produces objects about three times faster than conventional 3D printing, which means jobs that once took about nine hours now only take three, according to Kazmer, who lives in Georgetown.

"The invention greatly improves the quality of the parts produced, making them fully dense with few cracks or voids, so they are much stronger. For technical applications, this is game-changing. The new process is also cost-effective because it can be used in existing 3D printers, with only new software to program the machine needed," Kazmer said.

整个过程花了大约18个月的发展。普利茅斯,马萨诸塞大学一个博士洛厄尔奥斯汀大肠候选人塑料工程,帮助验证技术一起Kazmer,谁在产品设计,原型和过程控制等议题讲授课程。他已经申请了对新技术的专利。
