SABIC, a global leader in the chemical industry, launched AMS31F filament–a breakaway support material for fused deposition modeling. The filament maintains rigidity during printing and has excellent pliability during post processing for easier removal of scaffolding at room temperature, which can help reduce the time required to produce finished parts.
The AMS31F filament is proprietary and for use with SABIC’s ULTEM AM9085F filament, a high-performance polyetherimide (PEI) material with high heat resistance and mechanical strength, properties needed in aerospace, automotive, oil and gas, and tooling applications.
The formulation was developed for use with ULTEM AM9085F filament to balance adhesion during printing, yet be easy to remove during post processing. AMS31F easily separates at room temperature. The filament’s white color provides a sharp contrast to the amber color of ULTEM filament, which allows operators to more quickly identify the structures to be removed.
The use of this filament gives designers greater latitude in defining part orientation that is better suited to optimize printing efficiency and part performance. Often the print direction chosen by operators is aimed at reducing structural support to minimize post- processing time and may not be optimal for the mechanical performance of the part.
AMS31F has high heat resistance and mechanical strength, is UL 94 V-0 compliant at 1.5- and 3.0-mm thicknesses and meets FAR 25.853 and OSU 55/55 requirements with low flame, smoke and toxicity evolution. ULTEM AM9085F filament offers excellent diameter consistency to help meet customers’ dimensional specifications.
Used together, the new breakaway support filament and ULTEM AM9085F filament are compatible with Stratasys Fortus Classic printers and a variety of open architecture industrial printers.
