Once you've got your model as a 3 body STL, STEP, or Rhino file, we can move on to some quick preparation in Rhino. But having gone through this process a few times, I'm mostly convinced that a little bit of volume overlap will make things easier to merge at the end.īut this is the way I first did it, and if you get to the end and your specific bodies don't merge well in Rhino, consider coming back here and adding more overlap between your three bodies. Using a Split feature, there is no overlap between your bodies, they are line-to-line perfect. But the above three body rule prepares you for most any type of shape. If you don't have a hole in the middle of your model, I suppose you could get by with not having the inner ring body. The reason we're doing this is because, if you don't, after you use Grasshopper to make your middle body all complex and lattice-like, it will have hundreds of jagged little lattice beams sticking out all along its edges, which make it a pain to hold, to use in an assembly, to attach to other models, etc.īy having three bodies, after we lattice the middle one, we will be able to merge it back with the inner and outer bodies to control what our part borders look like. What we're trying to get is a model that has, at a minimum, three bodies inside it:

This step is something you can do in any CAD software you have, but I'm going to do it in SOLIDWORKS, because I know that system much better than Rhino. You can tell you've done this step correctly when you can open Rhino and type in the command 'Grasshopper' to get a separate window: There are many other plug-ins for Rhino, and they all seem to have fun animal names (Weaverbird, Flamingo, Penguin) but these are the only two we're using.

Luckily, there is no license or cost associated with Grasshopper, so you can just download and run it if you have Rhino! (Rhino 6 automatically includes Grasshopper, Rhino 5 requires a download here.) In this case, that's Grasshopper, an open-ended visual coding language plug-in for Rhino: Unless we want to sketch and cut all those complex shapes out of our model BY HAND, we'll need a flexible, editable program to automatically do the grunt work for us. You should be able to go through this tutorial in MUCH less than 90 days, and hey, then you'll know a little Rhino for your next job!īut Rhino is just a CAD system. Official 90-day evaluation versions of Rhino 5 here. If you don't want to buy a $995 license of Rhino just for this tutorial, you can download an officialĩ0-day evaluation versions of Rhino 6 here, and the (I'm using Rhino version 5 because that's the license my company has, but Rhino version 6 is the most recent.) (If you have better ideas, don't be afraid to mention them in the comments!)įirst, get a copy of the 3D CAD package Rhino. There are obviously many ways to get this effect (since a lot of people do it) but I'm going to show you the one most accessible to me. Step 3: Downloading Rhino and Grasshopper.To do that, we're going to have to download two new pieces of software.

So that's why I started this journey: to learn how to take any CAD shape I can design and fill it with complex '3D Print looking' semi-repeating structures, and then print it. I work in 3D printing but had no idea how to automatically generate the complex '3D Printed look' that most of the industry uses as our standard! That's like a leather worker having no idea how to make a cow. I realized I could figure out how to make the faceted one on the right, by just reducing the poly count in my design software:īut I realized I had NO IDEA how to create that complex bunny on the left! Let's take those two pink bunnies as an example. (That last image of the bunnies is from user u/tawmaraff in the fun subreddit r/3Dprinting, which is worth checking out for more of this sort of thing.) Semi-random, sort-of-repeating structures that could NEVER be machined, inside a larger controlled shape, is how we let you know something is 3D printed.Īs an industry, it's sort of become our 'aesthetic': So recently I was at a trade show and I saw a LOT of things that looked like this in a competitor's booth:Īnd if you've been in the industry a while, you know that's sort of the 3D printing 'look', right? If you picked up an object and the outside looked like this, you would immediately know where it came from:Īnd if you picked up something that looked like this: Things are going to get weird from here on out. You'll have to download a few random pieces of software, do visual coding of computer algorithms, and there's even some Maths. We show how to use Grasshopper and Rhino to automatically generate complex Voronoi structures ready for 3D printing.Īt the very start, I want to let you know: this is going to be one of the hardest, most esoteric 3D printing tutorials I've written yet.
