3-D printer creates fiber-reinforced parts
Fiber This line of 3-D printers from Desktop Metal creates composite parts from PEEK, polyetherketoneketone (PEKK) and nylon 6 and consists of a low-temperature (LT) model and a high-temperature (HT) model. Each printer has two printer heads, one a fused-filament-fabrication (FFF) head that prints with filaments reinforced with chopped fiber, and a second head that lays down a continuous-fiber tape for high-strength reinforcement in critical areas. Depending on requirements, parts can be printed entirely with the FFF head, or the FFF head can be used to print the exterior surfaces and any portions where continuous-fiber tape is not required. Applications include manufacturing jigs and fixtures, as well as end-use parts for cars, electronics, consumer goods and bicycles.
What’s new? The printers, which feature Desktop Metal’s micro automated fiber-placement process. They will be commercially available in the second quarter.
Benefits Composite parts that are two times stronger than steel at an affordable price. The printers are being offered on a subscription model, with a three-year minimum term. The starting subscription price for the Fiber LT is $3,495 per year; the Fiber HT starts at $5,495 per year.
