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 costs. Luna asks the tough question: when does SLS stop making sense? They discuss the trade-off between SLS and injection molding at around 1,000 units, and why the powder handling and post-processing steps catch first-timers off guard. Plus, the hosts offer practical advice on service bureaus versus in-house machines — and why a Formlabs Fuse 1 or Sinterit Lisa might pay for itself faster than you think. If you're building hardware and tired of fragile prototypes, this episode spells out exactly when SLS earns its place on your bench. #SelectiveLaserSintering #SLS #AdditiveManufacturing #HardwareStartups #RapidPrototyping #NylonPowder #FunctionalPrototypes #Formlabs #Sinterit #DFM #ProductionReady #MedicalDevice #LowVolumeProduction #Business #Technology #FexingoBusiness #BusinessPodcast #ManufacturingTech Keep every episode free: buymeacoffee.com/fexingo
