Algorithm allows 3-D printers to “read ahead” of their programming to boost speeds. A major drawback to 3-D printing – the slow pace of the work – could be alleviated through a software algorithm developed at the University of Michigan. The algorithm allows printers to deliver high-quality results at speeds up to two times faster than those in common use, with no added hardware costs. One of the challenges for today’s 3-D printers lies in vibrations caused as they work. A printer’s movable parts, particularly in lightweight desktop models, cause vibrations that reduce the quality of the item being produced. And the faster the machine moves, the more vibrations are created.
