What is the minimum wall thickness required for FDM printed parts?

Last updated on Mar 30, 2026

The minimum wall thickness for FDM printing is 1.5mm, and the thinnest part of the whole model should not be less than 0.8mm to ensure printability.

All design files must have no broken holes. Keep main wall thickness above 1.2 mm, and ensure the thinnest feature is at least 0.8 mm. Thinner structures will bring printing failure and post-processing risks.
