Breakaway Filament Improves Productivity

The AMS31F filament, a breakaway support material for fused deposition modeling, maintains rigidity during printing and provides exceptional pliability during post-processing to enable easier removal of scaffolding at room temperature, which can help reduce the time required to produce finished parts. The filament is for use with SABIC’s ULTEM AM9085F filament, a high-performance polyetherimide (PEI) material that provides high heat resistance and mechanical strength which are optimal properties for potential aerospace applications, as well as for automotive, oil and gas and tooling applications.

AMS31F helps part producers increase their productivity by helping to reduce the time required to remove structural supports. The patent-pending material formulation was developed for use with ULTEM AM9085F filament to balance excellent adhesion during printing with the ability to easily remove the scaffolding during post-processing. Unlike competitive support materials that often require reheating to facilitate removal, AMS31F easily separates at room temperature, reducing post-production time. 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.

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. The ease of removing the AMS31F support filament gives the operator greater latitude in defining part orientation that is better suited to optimize printing efficiency and part performance.

By expanding design freedom and accelerating the support material removal process, SABIC’s new AMS31F filament adds to the value of using ULTEM AM9085F filament in demanding applications. High-performance ULTEM filament is made from SABIC’s proprietary ULTEM resin (PEI) technology. It provides 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 a low flame, smoke and toxicity evolution. ULTEM AM9085F filament offers excellent diameter consistency to help meet customers’ dimensional specifications. SABIC’s filaments are continuously monitored with a laser micrometer to help ensure adherence to stringent specifications for diameter consistency.

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.
