It seems there are even more ways to repair broken 3D models. Today we’re looking at trinckle.
German-based trickle is a 3D print service that can accept your 3D models and print them. But a common scenario they encounter is bad 3D models submitted by their clients. They often have to repair these models before they can be successfully 3D printed and trinckle has software to do this.
But now it’s not just for their clients. They’ve set up the service for everyone to use: simply upload your STL file and hit the “Repair” button and they’ll provide a download of the repaired 3D model. They say:
The automated repair service is based on algorithms, which were refined by trinckle 3D to match the needs of everybody – even inexperienced users. Those algorithms analyze the triangle structure within the CAD file and detect logical errors. These errors are fixed immediately by automatically placing or removing triangles and rotating misdirected normals. Due to numerous optimization efforts 95 % of incorrect designs can be corrected to this day. For the moment three kinds of formats are supported: ‚stl’, ‚3ds’ and ‚ply’. The repair service employment requires no knowledge regarding the repair processes whatsoever. The corrections are carried out automatically subsequent to the design upload. Only very rare errors nreed to be detected and corrected afterwards with the naked eye.
Of course, no repair algorithms can fix up pathologically bad 3D models properly, such as our test model imaged above. The repair process uses colors to indicate problem areas. (Yes, there were a LOT of problem areas in our model.)
Is there a catch? None that we can see, aside from the download process is an early jump out of their normal 3D print service workflow. In other words, if you continue through the workflow, you’ll end up requesting a print from trinckle. But you may want to do that anyway.
