Meet Mr Beam: a portable laser cutter and engraver kit for paper, plastic, wood, and other materials. This open source system is easy to use and able to decorate all types of surfaces. Mr Bean can handle various surfaces and thickness levels. It has height-adjustable legs, enabling you to set it up easier. Depending on the thickness of materials you are dealing with, Mr Beam can do the cutting in one or multiple passes. Most things can be engraved in one shot though.
Mr Beam can engrave cardboard, wooden surfaces, chocolate, leather, and even meat. It can also cut foil, paper, and many other materials (depending on thickness). To use Mr Beam, just connect it to your home router and bring a motif to get started (use a software like Inkscape to get started). Mr Beam comes in 2 sizes. You can get it on Kickstarter.
