BASF Forward AM Ultrafuse® Support Layer: complex metal geometries made possible

The Ultrafuse® Support Layer is a breakthrough material designed specifically for use in the metal FFF (Fused Filament Fabrication) process. When printing with stainless steel filaments like 17-4 PH or 316L, the metal particles fuse together during the sintering process. Without this specialised ceramic-based barrier, metal support structures would permanently weld to your part.

The Support Layer acts as a non-sintering interface between the part and its supports. This ensures that even after the intense heat of the sintering furnace, supports can be easily removed, leaving behind a high-quality surface finish and allowing for the creation of complex internal channels and ambitious overhangs.

Key benefits:

• Total geometric freedom: Enables the printing of complex parts, bridges, and overhangs that would otherwise be impossible in metal.
• Minimised deformation: Provides critical physical support during the debinding and sintering stages, preventing the metal part from sagging or warping under its own weight.
• Superior surface quality: Specifically formulated to leave a smooth finish on the supported areas of the stainless steel part.
• Simplified workflow: Engineered for easy mechanical breakaway after post-processing is complete.

Mandatory requirements & compatibility:

• Required print core: Must be used exclusively with the UltiMaker Print Core DD 0.4.
• Filtration: A HEPA filter is mandatory to capture fine particles. Use the Air Manager (S5/S7) or Top Cover (S3).
• Printer compatibility: Strictly for use with the UltiMaker S3, S5, and S7. The UltiMaker 3 family feeders are not designed for the abrasive nature of this material.
