 ### Testing the strength
 To test the strength I made a makeshift setup with a scale on a hook. Then I put the plastic test subject on the bar and pulled really hard until it broke. Then I could read the amount of kg needed to break it from the scale.

 I made 3 prints. One normal using normal settings. One with brick using `Bricklayers.py` and one using `bricklayersNonPlanarInfill.py` using the commands above.

 This is the end result. At the bottom are all the failed prints. At the top are the finished and tested prints. On the left there is the `bricklayers.py` print. The 2 in the middle have no modifications. The one on the right has the `bricklayersNonPlanarInfill.py` modification. The 2 on the left broke in the middle at the same point. Of the left one I got a measurement of 27,75kg. The one in the middle and right I didn't get the measurement because my phone couldn't record the screen of the scale. That's why im doing them again.

 I also noticed that the non planar infill broke at the same point twice. It could be because the print was getting unstable up there. Because the print failed a couple of times at that point when I was printing it without a solid platform.

 So if it was more stable during printing it may have been even stronger.

 ### 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.

 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.

 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.
