A Beginner’s Guide

Not every 3D model is ready for the printer. Whether you download it from Thingiverse or model it yourself, here’s what to check before printing.

1. Watertight (Manifold) Geometry

Your model must be a single, closed mesh with no gaps or loose surfaces.

2. No Non-Manifold Edges

These confusing edges can’t exist in the real world and will confuse the slicer.

3. Scaled Correctly

Make sure the dimensions make sense especially if your file was exported in inches but imported in millimetres!

4. Clean Mesh

Use tools like Netfabb or Meshmixer to clean and repair geometry.
