2026 Frikkin Lasers Challenge: Laser Bandsaw

A maker built a manually-controlled laser cutter dubbed the 'Laser Bandsaw' using a 7W NUBM44 blue diode laser mounted in a custom copper heatsink with a box-knife-blade beam dump. The device operates like a traditional bandsaw — always on and ready to cut — making it effective on balsa wood and paint removal. The project includes 3D-printed frame STLs and a pinout, submitted as an entry to the 2026 Frikkin Laser Contest. Safety concerns about uncontrolled beam reflections are noted both by the author and commenters.
