But sometimes you just want things to WORK, instead of searching for that setting for an hour. There was probably a good reason for this, some sort of STL setting I could have found in SOLIDWORKS or Rhino to make it work like I'm used to. So in this case I went through an alternate workflow, using a STEP file instead of STL (not the last time we'll have to change file types during this project):Īnd now I've got my separate bodies back in Rhino: Normally I would export an STL to Rhino, and that usually works fine:īut with all these 11 bodies right next to each other, for some reason Rhino isn't letting me separate them, with the result that all 11 are selected if you click on any one: So the next step is to export that into Rhino. The simplest starting point is some sort of rectangular test palette with many separate bodies we can tint.Īnd while I can easily CREATE those 11 separate bodies in SOLIDWORKS, it's harder to TEXTURE them there, especially with different levels of tinting that I'm aiming for. I like to use Rhino for applying transparencies to this type of print, since Rhino has the dual benefits of being good with multi-bodies (unlike Photoshop) and good at exporting transparencies for 3D printing (unlike SOLIDWORKS or Magics). Step 2: Controlling Transparency BY BODY.
So that's the general theory, but how do we control transparency in practice? The simplest way is BY BODY. Which leads to an output we can precisely control:

When a 7 head J750 is set up for full color printing, it usually looks like this:Īnd to achieve transparency, what we do is mix one of those CMYK colors with Vero Clear in different amounts, to achieve our different levels of transparency: You may remember from my previous Realism tutorial that you need 4 ink colors for full-color 2D paper printing, but 5 for full-color 3D printing, since you also need to supply the white ink in lieu of white paper. But it's hard to create different gradients of color with just one input. Single material 3D printers have some great resins and can produce very clear single color shapes. Step 1: How does 3D printed Transparency work?.With multi-material 3D printers, how do you control what's transparent and what's not? Especially when you've got clear sections above, behind, and even intermixed with your color layers? This tutorial covers controlling what's clear, what's opaque, and what's tinted, even in intersecting volumes printed as one solid part! Get ready to conquer the hardest task in 3D printing!
