We’re unable to accept STL files since we require either 2D vector files (DXF, DWG, EPS, or AI format) or specific 3D files (STEP or STP format) to price and produce parts. Learn more about the file formats we can accept and check out our design guidelines.
To manufacture your part, we’ll need a design file that contains only the cutting profile and ideally contains smooth curves rather than high density polygons.
Converting STL format files to DXF or DWG format
If you want to convert a mesh STL format file to DXF or DWG, this presents challenges since curves can be translated to high density polygons, and the exports will often contain projections of the tessellated faces.
Try exporting the original sketch of the part, or projecting the desired face of your part to a plane and then exporting that as a sketch. After exporting to DXF or DWG, check the 2D file in a free program like QCAD to ensure it will meet our design guidelines.
Converting STL format files to STEP or STP format
If you want to convert an STL file to a STEP format file, it will need to meet our 3D File Guidelines. We do not provide any multiaxis machining and cut all parts out of flat sheet materials, so your design must be set up accordingly.
You can try exporting the original sketch for the part or a STEP created from the extruded sketch profile, or try smoothing the faces using your design software.
Consider redrawing the part
If you don’t have access to the original STL design file or the exports don’t include all needed geometry, consider redrawing your part in a free CAD program like QCAD or Fusion 360. Additional options are listed in our Recommended Software guide.
This approach allows you to create the exact cut paths and any bends required, and may be the fastest way to move your project forward. Please note that we only provide 2D, full-depth cutting perpendicular to the surface of flat sheet materials at this time.
If you need assistance creating a file, our Design Services can convert dimensioned sketches or templates to CAD. Keep in mind that Design Services is best for mechanical or industrial parts. For help with signage or decorative items we recommend contacting one of our trusted Design Partners instead.
