# Nesting Mockups for 3D Printing
## Introduction
[0] Let's dive into how I nest mockups. I nest these the same on every slicer, every printer that I use. It's incisal edge down with an adequate pattern and distribution of supports on the incisal edges. So, I'm going to demonstrate in Rayware Cloud. I'm going to go ahead and go find a mock up on my computer. Let's see.
[29] Mock up. And what I call it in Rayware since there's not a mock up function, I don't like to call it veneers. I actually like to call it denture teeth because, it's like an arch of teeth. And so denture teeth, I find, does a pretty good job off the bat. Let's go ahead and call it arch kit on the pro two. We would probably print Apex as a good material to do mock ups out of. So let's go ahead and hit prepare print and see what the algorithm does for us.
## Preparing the Print
[55] I find that, you know, Rayware sometimes does a really good job or sometimes it has a mind of its own. So you kinda kinda watch it. Alright. Actually, this is beautiful with a few little things that I would like to change. Rayware is notorious for not supporting the mesial incisal edges of your mock ups. That would leave you with really distorted or slightly distorted incisal edges.
[73] So, if you look at our rule of three, it didn't quite put three and we got one right here. This could be a point of failure which would then cause the mock up to fail. So let's just go back to let's turn this sweet sweet little autopilot off and go to supports, add remove individual supports, and check this out.
## Adjusting Supports
[91] On the centrals, I'm gonna have four supports, making sure to get my mesial incisal. My laterals, I'm gonna have three. And every other tooth, I'm gonna have three supports. This is what you're gonna do. This is never gonna fail you guys. If you do this, and I'm assuming that your mock up is at least 250 to 300 microns thick, you're not gonna get failures.
[114] If you have a poorly designed mock up that is beyond the limitations of your printer as it relates to thickness, you'll get misprints up here and thin areas will have holes in it. But if your optical path is clear and you have it supported like this, it's a % success rate. Seventeen minutes, this would print with the Arch Kit, on the Pro two.
## Conclusion
[136] This is awesome. I do these a few times a day for patients, and I can't I can't remember the last time I had a failure of a mock up print. So, super predictable if you use these techniques. I hope this helps you guys increase the predictability of your mock up prints chair side.
