Selective Absorption Fusion (SAF)

Utilized by the H Series Production Platform, Selection Absorption Fusion or SAF is a uniquely different powder bed fusion technology that was jointly worked on by Xaar and Stratasys, after more than 10 years of research and development. If it’s the manufacturing consistency that you are looking for, whether it’s for two parts or thousands of parts, SAF is your option with its unvarying and dependable process that overcomes the shortcomings of existing 3D printing solutions.

SAF when paired with the H Series Production Platform provides the accuracy, repeatability, and process control essential for consistent production and competitive part costs.

THE TECHNOLOGY

SAF uses an infrared-sensitive HAF (high absorbing fluid) to fuse particles of polymer powders together in discrete layers to build parts.

Using Big Wave powder management, powder is distributed across a bed where industrial grade Piezo-electric print heads jet the fluid selectively to create each layer of the part. This is followed by exposure to the printer’s fusing lamps, where the areas with HAF “selectively” fuse the powdered particles together but leaves the adjacent material unfused.

This is repeated until the parts are completed.

THE RESULT

When the parts have finished printing, they are embedded in a “cake” of unused, loose powder. The cake is then removed and allowed to cool. The cake is then broken apart to extract the printed parts. Parts can be used as it is or post-processed if needed.

KEY BENEFITS
