3D Systems SLS Printers

Selective laser sintering (SLS) uses a laser to fuse fine nylon and elastomer powders layer by layer into strong, functional parts. The surrounding powder supports each part as it prints, so there's no need for support structures. You can print complex geometries, interlocking assemblies, and full builds of nested parts in a single run. SLS is a proven choice for end-use production parts, durable prototypes, and short-run manufacturing.

Industrial-Scale, Process Controlled Additive Manufacturing Solution for Selective Laser Sintering

Production-Grade SLS Workflow Solution

The SLS 380 is a high throughput SLS additive manufacturing solution with unprecedented levels of throughput, consistency, performance, and yield. Optimized for those who want to take the next step in integrating additive manufacturing into their factory-floor ecosystem, 3D Systems’ SLS 380 and its complementary software, material handling, and post-processing solutions answer the demand for cost-effective batch production parts.

100,000 Thermal Data Samples Per Second

The algorithm manages eight separately calibrated heaters, together with an integrated high-resolution IR camera that captures over 100,000 thermal data samples from within the build chamber per second. This data, together with the IR sensor, maintains temperature stasis for every part build-layer, for the duration of the build process. With a more consistent thermal uniformity across the build process, manufacturers can now deliver more dimensionally stable parts with better mechanical performance, higher repeatability, and greater yields – all with fewer human interventions and lower overall operating costs.

What is Selective Laser Sintering (SLS)?

Selective laser sintering is a powder-based 3D printing technology that uses a laser to fuse material layers into a final part. After the laser traces a cross-section of the CAD design(s) onto a material layer, the build platform lowers and another layer is fused on top. The build platform continues to lower until every layer is built and the part is complete. 3D Systems’ SLS materials include a range of optimized nylon and elastomeric powders.
