Selective Laser Sintering (SLS)
NEXAMS Leading the Way in Selective Laser Sintering for High-Performance Parts and Agile Programs :contentReference[oaicite:0]{index=0}
Selective Laser Sintering (SLS) is an advanced AM 3D printing technology that fuses powdered thermoplastics—primarily nylon (PA11, PA12) and TPU—with a high-power laser to create solid, functional components layer by layer. We actively collaborate with Vendors and Manufacturers to make sure every material choice and setting reflects real-world constraints, while offering Support that feels personal, local, and genuinely nearby to teams making time-sensitive decisions. At NEXAMS, our process helps any Supplier and all Suppliers in your chain validate complex geometries, iterate with confidence, and uphold ethical, human-centered quality standards. The self-supporting powder bed enables intricate internal channels and nested builds, shortening lead time and reducing waste; our engineering team provides clear design-for-SLS rules, build-orientation choices, and post-processing options so Vendors and Manufacturers can move forward with transparent trade-offs and accountable decision-making Support. From rapid prototypes to low-volume end-use parts, SLS helps de-risk product development by delivering strong, isotropic parts and reliable repeatability across batches—especially valuable to Suppliers operating in local or nearby markets. :contentReference[oaicite:1]{index=1}

How Costing Works
Cost in SLS depends on powder type, part size, packing density, layer thickness, and post-processing. Because there is no hard tooling, upfront investment stays low and short runs become economical. We optimize nesting, orientation, and refresh ratios to reduce material usage and print time, while presenting clear trade-offs that help Vendors, Manufacturers, and each Supplier make informed choices. Our finishing plans (media blasting, dyeing, machining) are scheduled early so lead times and total landed cost remain predictable—backed by responsive, ethical Support for local partners and nearby distribution. :contentReference[oaicite:18]{index=18}
