Laser cutting eva foam

Post by jibjabst »

Would it be possible to laser cut a depth in eva foam without too much heat being generated?
So if you had a 20mm thick peice of foam, you could cut squares out to a depth of 16mm, (say 60x25mm) or would you have to really cut out that shape from a 16mm peice of foam.

Would lasering a area 60x25mm be a problem?

Cheers

You will have a lot of trouble trying to regulate the cut depth due to non uniformity in the material. It will need to be cut through for best results.

EVA foam is much more difficult to cut as the thickness increases, 20mm will require around 100W for clean single pass cutting. It can be cut with much less power but the edges/corners will melt due to the slower speeds required.

This may not be a problem depending on the application, in fact the results may be desirable (rounded edges occur on the top surface only).

The size is no problem.
