NatureWorks is the world’s leading manufacturer of Ingeo PLA biopolymer. It introduces Ingeo 3D450 which is a new break-away formulation for use in dual extrusion 3D printers. This latest clean, fast mechanical break-away of Ingeo 3D450 support structures bring in high finish quality, reduction in post-processing time and improvement in overall productivity.
The applications for Ingeo 3D450 support material are inclusive of complex industrial parts like jigs and fixtures, patterns for investment metal casting, and architectural and retail models. Ingeo 3D450 is specifically designed to work with the Ingeo 3D series of grades, including 3D850 and 3D870. Although, these were developed with the purpose of 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 break-away formulation does away with speed and buildability issues sometimes faced with soluble support materials such as polyvinyl alcohol (PVA) or high-impact polystyrene (HIPS). As compared to these soluble supports, Ingeo 3D450 has much longer and more stable shelf life which ultimately reduces moisture sensitivity during printing.
Additionally, it lessens the need for post-processing with its clean break-away from a build. The new grade is compatible with large format printers. Since Ingeo 3D450 break-away supports do not rely on solvent baths for removal, 3D450 avoids the size constraints encountered with needing to submerse a build.
“MatterHackers PRO Series Breakaway Support, using Ingeo 3D450, works well offering clean printed surfaces and clean breakaway material. It is more convenient than other, dissolvable, support offerings. There was no residue on the hot-end, and we found no filament or printing issues.” claimed a source.
