Engraving Polyurethane Foam


There are 3 types of engraving possible with laser cutting. Area engraving, line engraving and a combination of both.

Area engraving is great if you need to mark a large area on the surface of the material. To specify area engraving set your shapes to have a fill color of black with RGB values of 0, 0, 0. The way this engraving is performed is like an old dot matrix printer except instead of dots of ink it uses pulses of the laser beam. This is a surface finish not deep enough to be used for pocketing or inlays. The depth of the engraving ranges between 0.1-0.5mm.

Line engraving is like a really shallow cut. To achieve this effect the stroke color to red with RGB values of 255, 0, 0 and set the stroke style to a width of 0.01 mm. The laser beam follows along the red lines that you have in your design and marks the surface of the material. The result is crisp but it can be a time-consuming technique if you have a lot of small details like text.

Using a combination of both engraving types typically gets the best result. Set your shapes to have a fill color of black with RGB values of 0, 0, 0, the stroke color to red with RGB values of 255, 0, 0, and set the stroke style to a width of 0.01 mm. The line engraving causes the laser beam to trace around the edges of the engraved areas making them more crisp and bringing the details to life.

Typical Uses

Polyurethane Foam is mainly used as padding for packaging but it can also be used as an acoustic panel.
