How Hardware Startups Use Selective Laser Sintering for Production-Ready Prototypes

Hardware Startups with Fexingo: Devices, Robotics, and Manufacturing Tech Companies · Jul 3, 2026 · 7m · transcript

In episode 88, Lucas and Luna explore selective laser sintering (SLS) — and why it's becoming the go-to additive manufacturing process for hardware startups that need functional, durable prototypes without the brittleness of FDM. They dive into the material science: nylon-based powders, the 170-degree Celsius preheat chamber, and why SLS parts don't have the weak layer adhesion that plagues fused deposition modeling. Lucas walks through a real case — a medical device startup that used SLS to iterate 12 versions of a surgical tool handle in three weeks, saving six figures in tooling…
