Design Guides

DFM rules, tolerances, radii, and wall thickness for manufacturable parts.

  1. 01 DFM Overview: Design for Manufacturability on OpusFab What design for manufacturability (DFM) means, why it affects price and lead time, and how OpusFab flags issues automatically when you upload.
  2. 02 Minimum Radius and Wall Thickness Why sharp internal corners and thin walls are the most common CNC problems, the minimums to design to, and the thresholds OpusFab warns at.
  3. 03 Tolerances Explained What a tolerance like ±0.05 mm means, the standard tolerances on OpusFab, how finishes change dimensions, and when tighter tolerances cost more.
  4. 04 CNC vs 3D Printing Design Rules Side-by-side design rules for CNC machining and 3D printing on OpusFab: undercuts, thin walls, holes, threads, text, and supports.
