EnvisionTEC introduced what it says is the first industrial-scale 3D printer for producing woven fibre composite parts. The SLCOM 1 uses a process the company calls Selective Lamination Composite Object Manufacturing, which allows building composite parts using layer-by-layer laminated thermoplastic composite fabric sheets from a roll. Build volume of this first printer is 24inch x 30 inch x 24 inch It can process a wide range of custom-made thermoplastic reinforced unidirectional or multi-directional woven fibres. Composite matrix materials include woven glass fibre, woven carbon fibre, or woven aramid fibres reinforced with a choice of nylon 6, nylon 11, nylon 12, PEEK, PEKK, and polycarbonate. Composites can be tailored for toughness, environmental resistance, vibration dampening, low flammability, high wear resistance, and high strength-to-weight ratio. (Source: EnvisionTEC)

Israel-based start-up XJet has been talking about its novel direct 3D metal jetting technology since at least last year. At this week's RAPID 2016 show, the company introduced its NanoParticle Jetting system, the first commercial 3D printer that uses inkjet technology to make high-quality 3D-printed metal parts like the one shown above. The company's president and CEO was the founder of Objet, the company that invented polymer jetting 3D printing technology and is now owned by Stratasys. XJet says its process produces much higher resolution than other 3D printing metals techniques such as laser sintering or electron beam melting. It's also much faster, about five times as fast as direct metal laser sintering, and produces higher-density parts. (Source: XJet)
