9 New 3D Printing Technologies: Composites, Metals & Multimaterials
Ann R. Thryft, DesignNews.com, highlights 9 new 3D printing technologies:
With the Stratasys J750, prototypes can include can include a vast array of colors, materials, and properties in the same part – more than 360,000 different color shades plus multiple material properties ranging from rigid to flexible and opaque to transparent.
MarkForged introduced its MarkTwo industrial 3D printer, which produces carbon fiber, fiberglass, or Kevlar continuously reinforced composite parts.
Engineers at the University of Bristol in the UK have developed a new type of composites 3D printing that prints parts with tailored material properties and complex microstructures.
Sciaky, the maker of aerospace-grade metal EBAM (electron beam additive manufacturing) 3D printers, has introduced what is its internal closed-loop control system for use only on its EBAM machines. The patented Interlayer Real-time Imaging & Sensing System (IRISS) is designed to provide consistent process control for part geometry, mechanical properties, microstructure, and metal chemistry for large-scale 3D-printed parts.
Scientists at the Swiss Federal Institute of Technology Zurich (ETH Zurich) have invented a different kind of metals 3D printing process: one that makes tiny, complex components from copper.
3D Systems’ ProJet MJP 2500 Series printers are equipped with the company’s MJP EasyClean System for no-hands, chemical-free finishing via non-toxic, melt-away wax supports, eliminating damage to delicate features.
A direct-ink writing 3D printer invented by Lawrence Livermore National Laboratory (LLNL) has been used to manufacture supercapacitors out of a graphene-based aerogel.
Italy-based 3ntr’s industrial A2 and A4 fused filament printers have three printheads, allowing up to three polymers to be printed simultaneously. The range of materials includes ABS, PC, PC-ABS, nylon, nylon-carbon, HIPS, PETG, PLA, and TPU.
German RepRap’s new X150 is a compact 3D printer. Its 0.4-mm nozzle enables highly detailed, precise prints up to a build size of 150 mm x 150 mm x 150 mm, with a print speed of 10 – 150 mm/s. Minimum layer thickness is 0.1 mm.
