This is the end result of the scan. Maybe in hindsight it wasn't smart to use the mat to scan because the scanner needs reference points and with a mat you take that all away because it looks the same all over the mat.
## SLA printer (resin)
Henk showed us how to ELEGOO Mars 3 worked. First we sliced the model in CHITUBOX. CHITUBOX is a program to slice 3d models for SLA/resin printers. Then we went to the printer to prep it and after that we needed to clean it.
### Slicing
For slicing we used CHITUBOX. It's a slicer that's supports the ELEGOO resin printers.

It looks like this. I wanted to slice something so could also do it later on myself.
First we need to import the file using the Open button at the top.
Once you've imported the file you wanna make sure your part is not touching the plate. ![alt text](image-11.png)
Because if you are printing direct to the plate it will be very hard to remove later on according to Henk.
Because we don't want to touch the build plate we are going to need supports.
![alt text](image-12.png)
To add supports we need to press this button to go to the support screen.
After entering the screen we can press auto support to automatically generate supports.

Once we pressed that we can go back to the other tab and press slice to slice it all to a file.

Then we can put it on a USB stick and start preparing the machine
### Preparing the printer

First Henk showed how to calibrate the plate for printing. You need a piece of paper and a alan key to calibrate the plate.

Once the plate is on the bottom you can set the Z axis on the screen to 0. And pull the paper up to straighten the plate out.

After that Henk poured in the resin. Always make sure when you're working with resin to use gloves.

After that we where trying to get the file loaded on the machine but it didn't show up. So first Henk formatted the drive to FAT32. Then I also did it on my machine. But after re-plugging the drive in my machine after putting the file back on. The file disappeared so we grabbed another usb stick. With the new usb stick it did read the file so we had a bad usb stick.
