Large flat and thin parts can warp due to uneven cooling. Avoid large solid flat areas, reinforce them with ribs and aim for uniform wall thickness.
Material shrinks as it cools; if different areas of the part cool unevenly (thick and thin zones, large flat surfaces), the part bends.
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…
Leave a clearance between separate parts or moving components: MJF and SLS – ≥0.5–1 mm, FDM – 1–2…
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…
