Models & planning

STL vs 3MF vs G-Code

STL is a triangle surface, 3MF is a structured model container, and G-code is a machine instruction stream. They belong to different stages of the workflow.

How to Scale STL Files Correctly

Scale from a known intended dimension, not from a guess about the file's unit. STL geometry does not identify whether coordinates represent millimeters or inches.

How to Check Model Dimensions

A bounding box gives the occupied extent of a chosen orientation. It does not describe every hole, tolerance or local wall in the model.

Why Print Time Estimates Differ

Slicer duration depends on its assumed motion and machine behavior. Real heating, firmware constraints and interventions can change completion time.

How to Check Printer Build Volume

Usable build area may be smaller than the physical bed. Keep clearance for generated structures and machine-specific exclusions.

Common 3D Printing File Problems

Unit ambiguity, open meshes, inconsistent orientation and incompatible machine files create different problems. Diagnose the file stage before selecting a repair.
