SLDPRT is a CAD file format used by SolidWorks to store 3D part models. It contains geometry, features, and parametric data for a single component in an assembly. SLDPRT files are commonly used in mechanical engineering and product design.
STL is one of the most widely used formats in 3D printing. It represents the surface geometry of a 3D object using a mesh of triangles. STL files do not store color or material data but are ideal for rapid prototyping and additive manufacturing.
Convert your .sldprt files to .stl right in your browser — no downloads, no installs. Everything happens securely in the cloud.
We never store your files permanently. Only you can access them, and they’re automatically deleted from our servers within 2 hours.
Turn your SLDPRT files into STL in just a couple of clicks. No registration, no limits — and it’s 100% free.
