I can’t seem to find a working setting to cut through my acrylic. I use a Sculpfun s30 pro and my acrylic is around 2mm and opaque. I have done it on high power and low speed and it still doesn’t cut cleanly through, though the shape is visible on the other side of the acrylic. On smaller shapes, the acrylic melts on the bottom. Any suggestions are welcome.
Show some pictures of your results. Which color is it? Only black and certain colors work, blue for example doesn’t.
You could try something around 200 mm/min at 80% and one or two passes.
The larger picture on the bottom is the front, which is gold in color, and the back is the two pics on top, which is silver.
I tried making a “Happy Birthday” cake topper at 100 percent power, 1200 mm/min, and I think I did at least 14 passes with this one, but it still didn’t cut through enough to separate it.
The small name top right of the picture was made with 300mm/min at 90 percent power, and i did 5 passes for it twice, (so total 10 passes), all this did was melt the bottom. Please do say if I am overdoing or underdoing or just completely doing something incorrectly. I am an amateur.
To me, it looks like it’s transparent acrylic with a coating on both sides. You can’t cut this using a diode laser. Only CO2 can cut through this. Can you try to check if the middle is different than the surfaces? There is no acrylic that is silver or gold colored in full, only on the surface. You would need black acrylic with a gold or silver side.
