Leave a clearance between separate parts or moving components: MJF and SLS – ≥0.5–1 mm, FDM – 1–2 mm, SLA – ≥0.5 mm. If the gap is too small, the parts will fuse or stick together.
In powder bed technologies, heat spreads into the surrounding powder – parts placed too close together can sinter together. In FDM and SLA, material can stick or supports can remain.
The recommended minimum wall thickness for 3D printing is 0.75 mm (down to 0.5 mm for some designs).…
The smallest recommended hole for 3D printing is about 1–2 mm in diameter; for precise holes (bushings, shafts),…
The most durable thread in a 3D printed part is a metal threaded insert, heat-set into a prepared…
MJF and SLS can produce moving assemblies in one piece – hinges, chains, rotating parts – provided you…
For snap-fits choose PA11 or PA12 (MJF/SLS) – they withstand many bending cycles. To prevent breakage, fillet the…
SLA and FDM parts are built with supports – orientation determines surface quality, strength and cost. MJF and…
