Selective Laser Sintering – SLS

SLS Parts
Let Adaptive Designs expand your manufacturing capabilities with production-grade nylon materials to produce tough, functional complex parts with excellent surface finish, resolution, accuracy, repeatability. SLS printers print in thermoplastic materials designed to offer you the full range of capabilities and isotropic properties, from rigid to elastomeric, high elongation, high impact strength, and high-temperature resistance. Get your parts in as little as 2 days.

Overview

Selective laser sintering (SLS) 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. The completed 3d printed parts are then excavated from the build powder and further cleaned by bead blasting.

Robust, Performance Parts

SLS technology produces tough and durable parts that excel in high-performance prototyping and end-use applications. We utilize 3D Systems DuraForm SLS materials that have been optimized, validated, and tested to ensure quality, with uniform 3D mechanical properties. We also offer materials from other suppliers on request such as those from Windform and ALM.

Cost Effective and Reliable

With SLS we can repeatedly and economically 3D print functional end-use parts with high resolution in a broad range of thermoplastic, composite and elastomeric materials.

Consistent, durable parts

Our customers count on this process for the toughest applications, year after year. SLS offers far superior living hinges, snap fit and other mechanical joints than any other technology. With the broadest range of materials available, SLS consistently produces strong parts with high thermal and chemical resistance. SLS is the most economical thermoplastic solution for large quantities of parts.

High-Throughput of Medium-Sized Parts

Our SLS printers have high-throughput of medium-sized parts (up to 330mm long) in the broadest range of thermoplastic, composite and elastomeric materials available in Selective Laser Sintering (SLS). This printing process produces durable parts for a multitude of applications such as housings, machinery components, complex end-use parts such as ducting, functional test parts and assemblies as well as healthcare products and tools.
