Selective Absorption Fusion, or SAF™ technology, is a powder-based additive manufacturing process that produces high-quality end-user parts. SAF is the backbone of the Stratasys H-Series manufacturing platform, giving you extensive control over the printing process to achieve accurate, consistent production at competitive part costs.

This technology uses an infrared-sensitive fluid (HAF = High Absorbing Fluid) to fuse polymer powder particles in layers. The proprietary Big Wave™ powder handling system distributes the powder across the print bed, while industrial-grade piezoelectric print heads inject the fluid into specified areas to create the layers of the part. The heat emitted by an infrared lamp passing over the impregnated powder layer fuses the layer area of ​​a given height, ensuring uniform thermal conditions across the entire length of the print bed and consistent part quality.

SAF industrial-grade additive manufacturing technology performs key 3D printing steps on the print bed in two phases but in the same direction, ensuring even heat distribution and consistency for all printed parts, regardless of where they are located on the print bed. SAF can also contribute to lower operating costs and increase their predictability. The Big Wave™ powder management system reduces powder aging, while the warranted, industrial piezoelectric print heads are designed to not require regular replacement.

H-Series 3D printers powered by SAF technology deliver industrial performance and consistent quality for end-user parts, guarantee competitive and predictable part costs, and provide controlled conditions for mass part production.
