I am trying to print a dual color marvin but I am having some problems. I am using Simlpify3d and I have tried two things;
1. I took the .stl Marvin into Rhino and split the face and ears apart from the rest of the body and used the “Dual Extruder Wizard” in simplify3d to put it back together. When I print, the face only partially prints and leaves “V” in the bottom of the face out. There literally is only a “V” where the face should be. Everything else but the face and the ears prints fine.
2. I took the Solidworks file into rhino and I made the same two features solid and I have the same problems.
Does anyone have any better luck printing in two colors or have a model I can use?
Thats what I did, I made an STL file for the face and ears and one for the body. I imported them both into simplify3d and use the wizard to combine them which automatically creates two processes for the two colors.
Looking at your STLs the problem is obvious. You separated the parts of the mesh, but you didn’t make them solid, manifold objects. Either one of them. You need to close the holes, make them solid objects, and, to make them nestle into each other a little. I’m not sure the steps to do this in Rhino, but I could do it on Blender lickety split.
I spent way too long on this this morning, and there’s still a small part that isn’t right (see if you can find it), but here you go.
See how these models are solid objects with and inside and an outside that nestle into each other? This is the way it has to be to work. Marvin1.stl 1 (198 KB) Marvin2-Body.stl 1 (526 KB)
How would you rocommend making them sold so when I put them into Simplify3d I could load them separate and all the program to combine them into one object. I tried a model that was solid shapes instead of surfaces and had the same problem for some reason.
So the process involved making solid shapes from the shells that you made wasn’t as straight-forward as I would have liked. Mostly it involved locating the non-manifold edges and extruding them to a solid shape, then capping the hole by filling it in with an N-Gon. When I tried to make one model then boolean difference the other out of it, well it didn’t go well. Boolean doesn’t tend to like it when object have exactly intersecting points. So I basically ended up repeating the same action twice for the positive and negative spaces, and hoping that they were close enough. I haven’t test printed it, but I assume it’ll be fine.
Hey, don’t go uploading that model. I’m going to do it. Just need to talk to the 3DHubs people first.
Okay, I’ll test it tonight. I won’t upload it anywhere. Are you trying to get permission to upload it? I can probably get a answer a lot faster, what do you need?
