A bad edge is an edge (connection between 2 vertices) that is not properly connected to a neighbor. Several bad edges together form a bad contour.
Bad edges / contours are a data error that needs to be fixed in order to use the 3D data for printing.
What can I do to solve the problem?
Bad edges and contours are caused by edges that are too far from each other to be stitched together by our fixing algorithm or missing triangles that result in holes in your model, in intersecting or overlapping triangles. We advise to go back to your 3D modelling software and review your model for any topological errors and reupload the file.
Please also check the STL export settings. You could also try uploading a different file format. You can find the accepted file formats here:
We accept the file formats STL, 3DS, 3DM, OBJ, WRL, MATPART, STP, SKP, SLDPRT, STEP, CATPART, IGES, MODEL, MXP, and MGX.
For other file formats you can request a manual quote. In that case, please compress your file(s) (e.g. as a ZIP, RAT or 7z file) and ask for a manual request. One of our support engineers will then contact you.
File formats with color information
Some file formats are able to include colors or textures in the file (e.g. colored STL), while others store the texture in a separate image file (GIF, JPG or PNG) and map-file (OBJ).
If your model has textures, group all files related to the model into a ZIP file and upload it. To show and handle the textures correctly the archive should not contain any additional folders, this way we will be able to process all necessary info to print it the way you want.
How to check? Well, if you see your texture in the 3D print lab preview, then we have the info. However, if you see a mono-colored or un-textured model, it’s possible there’s some info missing. If this happens, check your export settings and the 3D file format used.
