# Nesting Implant Crowns in Rayware
## Introduction
[0] I'm gonna go in how I nest implant crowns in any slicer, but I'm gonna be using Rayware as a demonstration. So I'm in Rayware cloud, and I hit a new print job. I'm gonna go to my computer and load my implant crown. [13] And let's see. I'm gonna go ahead and call this implant crown. It's very important to pick the appropriate application for what you're printing. Let's do it on the arch kit ceramic crown material and hit prepare print and see how Raywear does. Raywear actually does a really good job usually with implant crowns where it's gonna auto rotate it.
## Orientation and Nesting
[31] Where the, as you read the book, you know that the fitting surface needs to be parallel to the build plate. And as I say that, it it it didn't quite nail it for this particular case, but let's go ahead and show you how I would like to nest nest this. I like my tube for my tie base to be perfectly perpendicular to the build plate, and this flat surface here that fits down on the tie base to be perfectly parallel to the build plate. So let me show you how I do that. First, I turn off the sweet autopilot mode. I go to orientation, and I go to the select base. Now select base is a feature that in every slicer has it, that when you click a certain surface, it will flip that restoration to be perfectly flat.
[73] On the build plate. So I click the fitting surface of my tie base to be perfectly flat on the build plate. So then all I do is hit exit select base and I'm gonna go ahead and rotate a 90 degrees or 80 degrees. Sorry. So that the top of this tie base surface is perfectly parallel to the build plate and my tube is perpendicular to the build plate. I'm gonna hit confirm.
## Adding Supports
[97] This ensures actually that this margin is gonna be printed in one layer and it's gonna be the most beautiful margin you've ever seen as it relates to fit. Now as a general rule, you know that you need at least three, if not four supports on the incisal edge of the restoration. So I'm gonna go ahead and go to supports, add remove individual supports, and I'm gonna go ahead and add four. Now when you see implant crowns that have some red areas on the cingulum, I'd usually like to dabble with the one to three little supports like that, especially around the tube cylinder to make sure that that is perfectly shaped and not distorted from my screw that's gonna go in there. We can see we have a beautifully nested restoration that's gonna be a % successful in anything that you print.
## General Guidelines
[140] With any software. Now this is the exact same way I would nest this in the Midas, so there's no change to that. So as a general rule, just to recap, you want the fitting surface of your tie base to be parallel to the build plate and the tube screw channel to be perpendicular to the build plate like that. That is awesome. You want at least four supports on a central for your incisal edge. If it's a little lateral or mandibular, maybe you could get away with three.
[166] And then you want to support big cingulums that are overhanging especially with the screw channel going through them. So this in a nutshell, I think, is going to be successful on every single printer on the market with any slicer. So this is one thing that I've learned over the years. Printing implant crowns can be a little tricky. So this solves all your major fit issues. Now one thing that you need to understand is certain printers will over burn the screw channels especially.
## Printer Specific Adjustments
[191] Earlier SprintRay printers. They'll, they'll basically because they're the technology is such that it has a lot of, over cure of cylinders. You have to accommodate that in your slicer software. So let me just show you how to do that. If I go down and I select one of their earlier printers like the Pro 55, you should see under the advanced settings.
[211] Let's see. There's this fit offset, and you wanna go at least 50 microns looser. So the first dot is 50 microns. This second dot is a hundred microns. And so that is actually going to loosen that screw channel at the expense of the, wall width around the tie base. So you have to take that into consideration.
## Conclusion
[237] And this is kind of a band aid, because many cam softwares, milling softwares to auto detect the tube and do this very same thing for your mill. So slicers are starting to do this. It gets cool that Raywear has this. I think that they might add it for their other printers as well as well just because of library issues with implant crowns. So super cool way to do that, is to change the fit there. You will not find it currently when you pick the Pro two.
[262] It doesn't quite exist yet, but I think they're gonna maybe add that back. Alright. So that is how I nest implant crowns.
