SABIC, supplier of diversified chemicals has announced the launch of AMS31F filament, the company’s breakaway support material for fused deposition modelling in additive manufacturing. The new AMS31F filament maintains rigidity during 3D printing and provides 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, which is a high-performance polyetherimide (PEI) material that provides high heat resistance and mechanical strength. These characteristics are optimal properties for potential aerospace applications, as well as for automotive, oil and gas and tooling applications.
The new SABIC AMS31F filament is said to help part producers increase their productivity by helping to reduce the time required to remove structural supports. The company’s 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, SABIC’s AMS31F filament easily separates at room temperature, reducing post-production time. In addition, the filament’s white colour provides a sharp contrast to the amber colour of ULTEM filament, which allows operators to identify the structures to be removed more quickly.
The new AMS31F filament from SABIC also enables greater design flexibility. Often the print direction chosen by operators is aimed at reducing structural support to minimise post- processing time and may not be optimal for the mechanical performance of the part. SABIC noted that 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.
Keith Cox, Senior Business Manager, Additive Manufacturing, SABIC, said using structural supports to print parts with complex geometries is essential, but it can also be quite challenging. Removing traditional supports from the finished part often involves time-consuming processes that can negatively impact productivity and quality, he added. Cox noted that by offering a complementary support material for the ULTEM AM9085F filament, SABIC is providing a complete material solution that helps customers save time and effort. “Additionally, the ease of support material removal provides part designers greater flexibility in defining print orientation to optimise part performance,” he said.
