What Is Selective Laser Sintering (SLS)?
SLS 3D Printing in NJ, NY & CT
Selective Laser Sintering (SLS) is an additive manufacturing process that uses a high-powered laser to fuse powdered materials layer by layer into solid, 3D objects. This method allows for the production of parts with complex geometries, excellent mechanical properties, and no need for support structures during printing. SLS is ideal for functional prototypes and end-use parts.
The Benefits of Selective Laser Sintering (SLS)
Durability & Strength
SLS parts are known for their high strength and durability, making them suitable for functional applications, even under mechanical stress.
Complex Designs
SLS can produce complex geometries, internal structures, and assemblies that traditional manufacturing methods may struggle to create.
No Support Structures Needed
Because the powder bed supports the part during printing, SLS does not require additional support structures.
Material Versatility
SLS works with a wide range of materials, including nylon, glass-filled composites, and flexible polymers, providing versatile options.

Our Selective Laser Sintering (SLS) Process
1. Design Review
We work closely with clients to ensure that the design meets all functional and performance requirements before proceeding with printing.
2. Material Selection
Based on your project needs, we select the best material to achieve the desired mechanical properties, durability, and flexibility.
3. Sintering Process
The SLS machine uses a high-powered laser to sinter layers of powder material, creating parts with high precision and strength.
4. Cooling & Part Removal
After printing, the parts are cooled and carefully removed from the powder bed. The unused powder is reclaimed and recycled for future builds.
5. Post-Processing
Parts can undergo post-processing steps such as cleaning, polishing, or surface treatments, depending on the desired finish.
6. Quality Control & Inspection
Each part is inspected to ensure it meets all dimensional and performance specifications before packaging and shipping.
