Right: Nature- works has
extended its range of PLA
products for 3D print applica-
tions to provide better impact and thermal resistance
production with 3D printing, not on prototyping. Therefore we work in close co-operation with OEMs directly. We do not believe that you can do mass customisation with an every-day material. What customers need are tailor-made solutions - material and machine – they can control.” According to Lehmann&Voss, laser sintering produc- tion of plastic components offers an additional level of design freedom, as well as new engineering opportuni- ties. Consequently, the company sees it complementing, rather than competing with, injection moulding and other manufacturing techniques. It says this means that materials and their properties should correspond to those currently used. The company is developing base polymers for laser sintering, ranging from PP to PEEK, which are then modified to specific requirements in terms of mechanical properties, colour and functionality.
Bio-based selections New from NatureWorks is Ingeo 3D860, a specific PLA formulation for 3D print filament applications designed to add impact resistance and heat resistance to finished parts. The company says 3D860 builds on the 3D850 grade that it launched in mid-2015 and complements its injection moulding and profile extrusion ABS replace- ment formulations (also introduced in 2015). All of these Ingeo formulations are claimed to provide a practical and cost effective alternative to a broad range of styrenics in terms of performance and life cycle assessment. Applications for the PLA filament are expected to include industrial tools and jigs for manufacturing, electronics, toys and prototyping. According to NatureWorks, Ingeo 3D860 rivals ABS in
3D printing filament
supplier 3Dom is offering the new 3D860 PLA from Nature- works, which is designed to simulate ABS
terms of impact and heat performance and can be used for home and industrial printing of durable parts, in addition to serving as an option for prototyping injection moulded goods. A brief 10-15 minute period of annealing at temperatures of 100-115°C (212-239°F) is recom- mended to achieve thermal resistance and impact performance similar to ABS. NatureWorks is initially introducing the 3D860 product through filament suppliers 3Dom and 3Dom USA.
“Many brands desire a bio-based, low carbon footprint
alternative to styrenics,” says Dan Sawyer, Global Leader, New Business Segment, NatureWorks. “With the addition of Ingeo 3D860, we are providing an option that now enables users to create functional industrial parts or finished goods. We have had positive feedback from some industrial users that now view this as a viable alternative to ABS for some of their production jigs and fixtures. 3D860 also allows for rapid prototyping with the ability to approximate the physical properties achievable in injection moulded parts made with ABS or with one of our Ingeo durables formulations.” US-based Clean Strands has launched a new online
marketplace for environmentally-friendly 3D printing filaments. The company sells 3D printing filaments made from sustainable materials including recycled coffee grounds, non-GMO wild harvested algae and wood chips. Clean Strands says that it has partnered with manufac- turers such as 3D Fuel, 3Dom USA, Filamentum and BnK to provide homes, schools and businesses with easy access to the most up-to-date selection of bio-derived 3D printing filaments. The Clean Strands online store debuts with eight 3D printing filaments, available in over 50 different colours and sizes.
