What Is Selective Laser Sintering?

Selective Laser Sintering (SLS) is a powder-based 3D printing technology that uses a laser to fuse material layers into a final part. The laser traces the pattern of each cross section of a 3D design onto a bed of powder. After one layer is built, the build platform lowers and another layer is built on top of the previous layer. This process continues until every layer is built and the part is complete.

SLS is the technology of choice for a range of functional applications, including those with snap fits, living hinges and other mechanical joints. The material range and platform sizes available for SLS also make it a great option for the direct production of products requiring strength and heat resistance.

About SLS 3D Printing

Self-Supporting Powder Bed Fusion for Complex Geometries

Selective Laser Sintering (SLS) is a powder bed fusion process in additive manufacturing that uses polyamide powder (often Nylon 12) to build parts layer by layer. Because each part is surrounded by unsintered powder, there’s no need for support structures—enabling rapid prototyping of intricate, complex geometries, internal channels, and fully enclosed features that traditional manufacturing can’t achieve.

Production-Quality End-Use Parts & Low-Volume Production

SLS delivers injection-molded component strength and durability—ideal for aerospace, automotive, and industrial design applications. With mechanical properties comparable to molded plastics (tensile strength up to 50 MPa), SLS supports short production runs, mass customization, and on-demand manufacturing without costly tooling or assembly. Its wear resistance and longevity also reduce replacement cycles and overall lifecycle costs.

Digital Inventory & On-Demand 3D Printing

By storing digital CAD files instead of physical stock, SLS enables a digital supply chain and digital warehousing strategy: print parts whenever you need them, with zero risk of degradation or misplacement. This on-demand manufacturing model cuts storage costs, accelerates time to market, and ensures consistent, high-quality end-use parts long after the original run.

Selective Laser Sintering 3D Printing Services

Our SLS 3D printing service harnesses state-of-the-art powder bed fusion to produce precision-engineered nylon components with outstanding mechanical performance. Utilizing premium Nylon materials, we deliver end-use parts featuring excellent tensile strength, impact resistance, and heat tolerance—ideal for aerospace brackets, automotive fixtures, and industrial tooling. By eliminating the need for molds or tooling, we accelerate product development and enable cost-effective short runs and mass customization

Our engineers collaborate with you to optimize part geometry for SLS 3D printing, leveraging Design for Additive Manufacturing (DfAM) principles to minimize build time and material usage while preserving strength. Features like lattice infills, variable wall thickness, and conformal cooling channels can be integrated seamlessly—enabling mass customization and performance-driven designs that traditional manufacturing can’t match.


Post-Processing & Surface Finishing:After sintering, parts undergo a suite of post-processing options to achieve your desired aesthetics and performance:

  • Bead Blasting & Tumbling: uniform matte texture

  • Dyeing & Painting: consistent, vibrant colors

  • Vapor Smoothing: reduced surface roughness for fluid dynamics and visual appeal

  • CNC Machining & Inserts: tight tolerances and integrated metal fasteners
