Demo Foamboard for Lasercutter

thingiverse

Every foamboard requires a test before cutting it on a lasercutter. WHY? The power needed depends on paper-quality and thickness. A store-bought foamboard from Bern, Switzerland, is used in the Demo-Object and requires: Cut: 25 / 40 / 30 (speed, max power, corner power) Semi-Cut: 80 / 40 / 30 Engrave: 100 / 30 / 20 Semi-Cut only cuts the top paper-layer and foam. This is necessary for bending objects as shown in pictures. Engrave is not done by lasercutter engrave-option since it involves a closed figure. To engrave lines and markings, use "cut" with low power as mentioned above. This technique is widely used by flitetest.com. Check their website to learn how to construct and use different cuts (A-fold, B-fold, C-fold). A simple example of a plane can be found at http://flitetest.com/articles/ft-simple-storch-build Be aware that more power needed results in more foam melting, increasing the space for glue. Use hotglue to assemble objects.
