NatureWorks, the world’s leading manufacturer of Ingeo PLA biopolymer, is introducinga new formulation for use in dual extrusion 3D printers, Ingeo 3D450. The clean, fast mechanical break-away of Ingeo 3D450 support structures results in parts with high finish quality, reducing post-processing time and improving overall productivity.

Applications for Ingeo 3D450 support material include complex industrial parts such as jigs and fixtures, patterns for investment metal casting and architectural and retail models. It is designed to work with the Ingeo 3D series of grades, including 3D850 and 3D870, that were developed for the professional printing market. At printing speeds up to 100 mm/s, Ingeo 3D450 prints and cools without warping even across large sections of support structures.

The Ingeo 3D450 formulation can reduce speed and buildability issues sometimes encountered with soluble support materials such as polyvinyl alcohol (PVA) or high-impact polystyrene (HIPS). Compared to these soluble supports, Ingeo 3D450 has a longer and more stable shelf life with dramatically reduced moisture sensitivity during printing, and reduces the need for post-processing with its clean break-away from a build. The new grade is compatible with large format printers, and since Ingeo 3D450 supports do not rely on solvent baths for removal, it avoids the size constraints encountered with needing to submerse a build.

Several partners have already beta-tested the new grade with positive results.

Titan Robotics will demonstrate Ingeo 3D450 on its new Atlas hybrid filament and direct pellet extrusion print machine during the Additive Manufacturing Users Group Conference and Tradeshow (AMUG) in Chicago from March 31-April 4. The demonstration will feature Ingeo 3D450 filament made by 3D-Fuel and will be held on Monday, April 1 from 10am to 2pm at the Titan Robotics booth 78.
