Just a fun little design I made to try some fine detailed engraving on some small pieces of laminated acrylic that I had. The pattern features larger dots in the centre circle and gradually get smaller towards the corners. This design could be engraved on any material but works particularly well with this white on black laminated acrylic.
I made the design using software called Affinity Designer and then imported into xTool Creative Space. The file can be edited to adjust the size of the design although the illusion effect is lost slightly when made really big.
A high lines per cm is crucial for detailed engraving and I would recommend always going to 200 or above for designs like this one.
The settings I used are listed above but these may need to be adjusted for other materials.
If you happen to also be using 1.6mm acrylic and cutting using a 5w laser the above settings should work perfectly for this project.
