A novel quasicrystal-resin composite for stereolithography

摘要: Abstract Laser stereolithography (SL) is an additive manufacturing technology which increasingly being used to produce customized end-user parts of any complex shape. It requires the use a photo-curable resin can be loaded with ceramic powders or carbon fibers composite parts. However, range available materials compatible SL process rather limited. In particular, resins reinforced by metal particles are difficult process, because fundamental limitations related high reflectivity intermetallics in UV–visible range. this work, unique properties Al-based quasicrystalline alloys develop new UV-curable such particles. The optical and filled studied they found process. volume fraction filler liquid optimized increase polymerization depth while preserving suitable rheological behaviour. Finally, 3D built SL. have improved mechanical compared unfilled (higher hardness, reduced wear losses lower friction coefficient) compete favourably other commercial resins.
