Your stock answer on materials says “various plastics”. I’m presently using ABS very successfully, however, I want to use acrylic, which is very brittle. Any advice?
Yes. Search these forums; lots of folks cut acrylic all the time with great results.
Hi - thanks for posting. Easel will give you some default baseline settings for working with acrylic. As Traxxtar mentioned there is quite a bit of information about working with acrylic on the forum. Here are a few links to get you started:
Acrylic is hard to cut! I've mainly been working on clear acrylic.
So far, I've had the best results using the straight 2 flute bit (the one sold here on Inventables and included in my End Mill Starter set) at a feed rate of 40in/min, 0.02" deep passes.
This works great up until about 3/16" deep, when there begins to be a lot of material against the bit that isn't being cut...just rubbing and generating heat. Then things start to get a bit melty. Small gobs of molten acrylic travel up…
I am new to the cnc router scene, just built my machine and love it. I did a practice run and it came out not bad. But what I really want to do is acrylic carving and cutting. I am totally lost as to what bit or bits to get to use on such a task. Any recommendations or suggestions are totally appreciative.
Yes, you're correct. typing mistake. must be 0.03 to 0.05. Sorry I was fly.
