You have an access to one of those mythical J750's? Nice! I got so many models and ideas I would test on that thing, but for now I'll stick to my trusty fdm machine.
BOIIE, thanks for the comment! Yes, the side walls and edges bowed out because I left them default white/gray in the bump mapping black-and-white screen (you see it at 5:49 in the video), and so they got pushed out as well, since the lighter the color is, the more it gets bumped/displaced. I've learned in later prints that if you REALLY want to keep areas from moving, I should have covered those areas in a perfect black (like a 0,0,0 RGB) and then they wouldn't have moved. It's not too bad to do layers like that in Photoshop, and if you really need to keep an area straight, I would probably do that in my later prints, if I was printing this again for a demanding customer. Hope that helps, feel free to email me at shuvom@grabcad.com with any other questions!
@@shuvomghose4219 Thanks for the reply. I got a trial version of the PS and cant get it to work. When I add a new 3D layer I get the message “The UVs on this 3D scene are missing or invalid. You may have issues painting on this scene or simplifying it. To fix this problem, Select ‘Generate UVs …” I dont know if thats critical. After that I dont have the Diffuse layer. So now I´m stuck. Do you know what I could do?
@@B0IIE , this might be getting too complex for youtube comments, remember you can always email me at shuvom@grabcad.com. But what's happening is you've imported an STL with no UV mapping, as it says. So there's nothing to show you on the Diffuse layer. I use a $60 program called Ultimate Unwrap3D to generate great UV maps for my STLs (see step 4 of my tutorial here: grabcad.com/tutorials/how-to-control-the-transparency-of-your-3d-printed-parts-the-hardest-task-yet). If you send me your STL I can generate a good UV map and send you back an OBJ, to show you what Ultimate Unwrap does. There are other programs that can repair UV mapping, like Rhino or Maya, but they cost a lot more. I could also send you a sample OBJ file with good UV mapping for you to do your test. But the error in Photoshop is a common one, when working with STLs that haven't been repaired/properly UV mapped.
One could make an awesome phone case with this!

Thanks for this tutorial. The sidewalls and edges look a bit wonky. Is there a way to keep them straight as in the original model?
