PEEK is a high-performance thermoplastic valued for high temperature resistance, chemical inertness and biocompatibility, widely used in medical, semiconductor and aerospace CNC components. PEEK has special machining risks including thermal buildup, melting and internal stress. This guide covers grades, tolerance rules, cooling strategy and medical compliance notes for PEEK CNC prototypes.

Metal 3D printing (SLM / DMLS) builds metal parts layer by layer for complex geometries impossible with CNC machining, such as internal lattices, conformal cooling channels and lightweight topology optimized structures. This guide compares metal 3D printing vs CNC, material choices, surface quality, cost and design rules for functional metal prototypes.
