STL: printing
Geometry-only, the de facto standard for slicers.
Decision中文
STEP to STL or OBJ?
STL and OBJ are both triangle-mesh outputs from STEP, but STL is purpose-built for 3D printing while OBJ is a general mesh that can carry basic color. Choose by whether you are printing or exchanging.

OBJ: general mesh
Supports basic materials via MTL for visualization.
Color?
STL has none; OBJ can carry simple color.
Choose STL when
You are sending the part to a 3D printer or slicer.
You do not need color or materials, only watertight geometry.
Choose OBJ when
You need a general-purpose mesh for visualization or interchange.
You want basic color/material support that STL cannot provide.
FAQ
Can STL store color?
No. STL is geometry-only; use OBJ or glTF if you need color.
Which prints better?
STL is the standard input for 3D printing workflows.
Is OBJ printable?
Some tools accept it, but STL is the safer, more universal print format.
