Cut and sculpt foam to make displays, packaging inserts, and prototypes. These kits include a hot knife for slicing through foam, a sculpting tool for carving, a freehand router with bendable wire for cutting out complex shapes, and a precision engraver for making intricate designs. You can work continuously on soft foam, but when cutting dense foam you’ll have to slow down and turn up the heat. Adjust the blade and wire temperatures depending on the type of foam you’re cutting.
