What is Selective Absorption Fusion?

SAF™ technology powers a new plastic powder bed fusion (PBF) process to achieve higher volume manufacturing of end-use production parts. This technology enables comprehensive control of the printing process to deliver accurate, consistent, and repeatable parts with engineering-grade thermoplastic materials, allowing the capability to replace injection molding. 

SAF™ technology produces small to medium functional plastic parts with tighter tolerances than SLS with an improved surface finish perfect for end-use components.

Built from the ground up with production-level printing in mind, SAF™ delivers exactly what you need – production quantities and competitive prices, all backed by the industry-leading production capabilities of Stratasys Direct Manufacturing.

How SAF™ 3D Printing Helps Lower Production Costs 

Selective Absorption fusion is a great option for building higher quantities of a single production part design or leveraging batching to build several types of production parts all at once while maximizing cost-effective production.

Primary cost drivers are material consumption and build height, so you can make your parts as intricate as you would like or consolidate assemblies with ease. Complexity is free with SAF™ technology. Nesting your parts will further maximize your budget by reducing the manufacturing cycle time for each build.

How does Selective Absorption Fusion (SAF™) Work?

Selective Absorption Fusion (SAF™) 3d printing is a polymer powder bed fusion process that uses industrial-grade piezo-electric printheads that jet high absorption fluid (HAF) onto a powder bed to define the area in which to form the 3d-printed object. 

The powder bed is then exposed to infrared (IR) energy. The parts of the bed that have HAF have a higher emissivity, which allows it to absorb more IR energy than the surrounding powder. This selectively fuses the parts in a layer-by-layer process.

Made for the manufacturing industry, the entire SAF platform is built around repeatability and reliability. The powder is added to each layer through a proprietary Big Wave process. This ensures that each layer reliably has enough powder regardless of how much is printed on that layer. SAF also uses an advanced thermal control system that guarantees part repeatability with every build. 

SAF has a unidirectional print process, meaning that every layer takes the same amount of time between fluid deposition, energy application, and powder recoating regardless of each part’s location in the bed or its complexity. 

The unidirectional print process and advanced thermal control allow for an industry-best nesting density (the total volume of parts divided by the available building space). This enables the manufacturing team to maximize space and put multiple types of geometries together in a build. This makes SAF cost-effective when manufacturing hundreds or thousands of 3D-printed end-use parts.

The parts are supported during the printing process by the powder itself, and once the parts have finished building, they must cool to room temperature. The parts are then removed by hand from the powder and cleaned off with compressed air and media blast, and unfused powder is able to be recycled into the next build which helps lower costs.
