Source high-quality parts for prototyping and production easily using selective laser sintering (SLS) 3D printing.
Selective Laser Sintering
Selective Laser Sintering uses high-powered lasers to sinter powdered material, binding it together to create a solid structure. It is often confused with another similar process called Selective Laser Melting (SLM), the difference being that it only sinters the powders together as opposed to achieving a full melt.
Parts are supported by unsintered powder in each layer, which remain spread across the build volume until each layer is fused together. Once complete, the part is removed from the remaining powder and cleaned by hand and using water/air jets.
Production Capacity
Selective laser sintering (SLS) is a powder bed 3D printing technology that produces highly accurate and durable parts capable of being used directly in end-use, low-volume production.
Maximum Build Size:
400 × 400 × 450 mm
Standard Lead Time:
2-3 business days
Dimensional Accuracy:
± 0.5% with a Lower limit of ± 0.15 mm (± 0.006")
Layer Height:
25-100 um
Advantages and drawbacks of SLS
ADVANTAGES
No support material is needed
Excellent layer adhesion
Fast printing process for functional, durable prototypes or end-use parts
Materials have good mechanical properties
DRAWBACKS
As-printed parts are rough to the touch due to surface porosity
SLS is prone to shrinkage and warping, especially on long, thin parts
Selective Laser Sintering Materials
PA
PA+GF
High strength
TPU 88A
Post Processing For SLS
Surface finishes can serve either a functional or aesthetic purpose. Surface finishes that serve both purposes are deemed cosmetic finishes, and are used for cosmetic parts. Producing cosmetic parts requires additional measures to minimize defects such as hang marks and scratches from tools.

High quality parts every time
Precision products machining
From factory audits to part inspections, we follow strict processes to ensure your parts always meet the highest quality standards.
IP protection
We take every measure to ensure the protection of your IP, which is why 27% of Fortune 500 companies trust us with their projects.
Certifications
Our manufacturing partners have all the necessary certifications for your project's needs (ISO 9001, ISO 14001, IATF 16949, ISO 27001).
TESTIMONIALS
Amazing experience. All the expectations fulfilled. Exceptional quality and surface finish. Lead time faster than initially stated.
During the process, we used HLHs capabilities to 3D print many prototypes. That meant we had the option to iterate very quickly, print objects, and test them to see if they were working correctly in terms of complexity, or too much complexity.
HLH has always given us exactly what we needed. We’ve received parts with holes in the right places, with the right finish, and on time. Their user-friendly website means faster turnaround.
