![]() ![]() The enclosure doesn’t have to be anything complicated, just some construction foam with a door to access the internals will do. Laser engraving and even more laser cutting produce a lot of smoke that is not healthy to breathe in, not to mention it smells horrible. One thing that you absolutely need with a laser, that you most likely don’t already have on your 3d printer, is an enclosure with a vent to the outside. This works because you are not using the heated bed and hotend during laser cutting, thus leaving a lot of energy available for the laser. Provided your laser uses the same input voltage as your printer, you can likely also use the already present power supply to power your laser. While you are lasering, you don’t need the part cooling fan, and it is straightforward to control it with gcode. One suitable method to control the laser is to use the part cooling fan PWM signal for the PWM input of the laser. If you also still keep all the 3d printer parts attached, you can quite quickly build a dual-purpose machine, with the laser diode being the only cost to your new laser cutter. By attaching a laser to the extruder, for example, you can easily convert your 3d printer to a laser engraver or even cutter. But you can not only use your 3d printer for printing, but it is also an XYZ motion platform. This is awesome, as there are so many things you can do with a 3d printer. Pretty much every maker has at least one 3d printer nowadays. ![]() ![]() How to convert a 3D Printer to a Laser Cutter ![]()
