Informazioni sullo strumento
OBJ is a widely used 3D modeling format, but 3D printing slicers generally require STL input. This converter extracts mesh geometry from OBJ files and produces clean STL output, handling coordinate system differences and scale adjustments for reliable slicing.

Domande frequenti
Does the converter support OBJ files with multiple objects?
Yes. OBJ files can contain multiple named mesh groups. During conversion to STL, all mesh groups are merged into a single solid geometry. If you need separate parts, convert each object individually.
Can I convert OBJ with textures to STL?
STL does not support textures or materials. Only the mesh geometry from the OBJ file will be included in the output. Any associated MTL files and texture images are ignored during STL conversion.
Do I need to upload the MTL material file with my OBJ?
No. Since STL does not support material information, the MTL file is not needed for conversion. Only the OBJ geometry data is used. Simply upload the OBJ file to convert.
Will the model dimensions change after conversion?
Conversione does not alter the actual dimensions. However, OBJ and STL may use different default unit conventions. Verify the scale setting in the conversion options to ensure the size matches your expectations.
How fast is the conversion for large OBJ files?
Conversione speed depends on the vertex and face count. OBJ files with millions of faces typically complete in a few seconds. Very large files (tens of millions of faces) may take longer depending on your device performance.
Can OBJ free-form curves and surfaces be converted?
Free-form curves and NURBS surfaces in OBJ files cannot be directly converted to STL. Only polygon mesh data is extracted. Curves and surfaces must first be converted to polygon meshes in modeling software.
