SAF 3D Printer

Selective Absorption Fusion (SAF) 3D printers use a counter-rotating roller to coat powder layers onto a print bed where high energy-absorption HAF fluid is selectively jetted to image the part layers. Industrial piezo-electric print heads jet single or multiple droplets of fluid according to the part requirement for fine detail or large areas. Using infrared energy radiated from an IR lamp, the imaged layers and underlying particles are fused across the span of the print-bed.
