Adding glass to sintered nylon roughly doubles tensile modulus and lifts heat deflection sharply, while cutting elongation at break by more than half and adding a third to the density. Here is when that trade pays.
Anyone quoting a universal breakeven quantity is guessing. Here is how the two cost curves actually behave, what moves the crossover, and how to work out your own.
A true living hinge depends on molecular orientation that injection moulding creates and sintering cannot. Here is what a printed PA12 flexure can realistically do, and how to design it.
What the real minimum wall thickness is for laser sintering, why the recommended range sits above it, and why most thin wall failures happen during depowdering rather than in service.
Delrin is stiffer and slipperier, nylon is tougher and printable. A datasheet-level comparison of acetal and polyamide for robot tooling, and how the manufacturing process decides as much as the material.
Heat set inserts put a durable metal thread into a sintered nylon part. How to size the boss, how installation actually works, what fails when it fails, and the alternatives worth considering.
