Preparing an STL File for FDM Printing

The essential checks to run before sending an STL file for FDM production.

STLFDMDFMFile Prep

Intro

A clean STL leads to faster quotes, fewer revisions, and a more predictable FDM print. The goal is to let the Creator plan production instead of guessing what the geometry means.

Prerequisites

Steps

  1. Make the model manifold; avoid open surfaces, flipped normals, and overlapping geometry.
  2. Check the thinnest walls. Very thin FDM walls can become fragile or unprintable.
  3. Think about orientation. Visual surfaces, support marks, and layer strength all depend on it.
  4. Leave tolerance around holes and fitted surfaces. Pins, screws, and press-fit areas need more than nominal dimensions.
  5. Choose a balanced export resolution. Too coarse hurts surfaces; too dense makes files unnecessarily heavy.

Common Pitfalls

Conclusion

STL preparation directly affects quote quality. Supplying context alongside the file helps Fabberworks Creators produce better prices and lead times.
