Open a SLDPRT file
in UltiMaker Cura.

Updated 2026-10-01

Cura cannot open SLDPRT files: SOLIDWORKS parts are not among the formats it imports. Convert it to 3MF below, then open the .3mf in UltiMaker Cura. Free Cura reads 3MF natively, with its units recorded, ready to slice.

Can UltiMaker Cura open SLDPRT files?
Cura cannot open SLDPRT files: SOLIDWORKS parts are not among the formats it imports. Checked against UltiMaker Cura's own documentation on 2026-10-01.
Why 3MF?
UltiMaker Cura reads 3MF, and 3MF records units and separate objects, so the part arrives at the right size. It is a mesh, which is what UltiMaker Cura works with anyway.
Is the conversion free?
Yes. Without an account, 5 conversions a day are free, with no card and nothing to install.
