We just got a new laser at work. It’s a ULS2.30 with a 30W laser tube in it.
I’m no expert just yet, but I went ahead and tied to cut some holes in a plastic lid. It turned out okay but I was hoping for better results. The lid is from a blue electronic project box that’s 2x4 by 1" with lid.
The problem is I don’t have this type of unknown plastic to make test cuts. So what can I do for best results?
For the record I know about the danger of some plastics that produce poisonous gases when cut. But the amount of cutting was very small and vented outside.
The attached sketch shows the setup I had.
The laser has pre-set values for ABS that I used as a starting point. With the actual thickness only a 1/16" at the point were the cuts were being done I increased the speed. The power is at 100% but the speed was changed from 3% (1/4") to 6% which I believe I went closer to 8% for 1/16". The plastic flamed up only a little at the corners and left ruff edges. The cut outs I was able to break out with force and I cleaned up the edges with a knife.
If anyone has done this type of cutting, please share any details.
Thank for any help.
