Warping on 3D printing piece

6 min read

Warping

The phenomenon of "warping" is one of the most common problems in 3D printing, particularly when working with thermoplastic materials that tend to shrink during the cooling phase of the material. The term "warping" means the deformation or lifting of the edges of the model from the printing plane,...

STL File Guide: The Standard Format for 3D Printing

What is a .STL file?

STL is a standard format for 3D models. 3D geometry is described by a mesh of triangles and dimensional information is contained in each individual triangle. Unlike other CAD formats, the object appears to be formed only by the external surface or "skin". The information of...
