But I've bought only the laser package and not the entire product. I've read the instructions from this engraving device before purchasing this laser. The chosen laser basically comes from a DIY package. So by using a 3D printer, it's not necessary to purchase a power supply, mainboard, motors and frame. And this printer already has a 12 Volt power supply and a mainboard to control the steppers, nozzle and fans. The idea is to convert an Anet A8 3D printer into a laser cutter. These range from cheap (low/medium power) mini laser machines (3.5 x 3.5 inch) to desktop size laser engravers/cutters. There are also various DIY packages with a diode laser. It is therefore not possible to cut wood with these. However, these lasers have very low power. You can remove a diode laser from any DVD burner and use it as a laser engraver. Therefore this Instructable is about a diode laser. The C02 laser have a much greater power than diode lases, but these are also a lot more expensive. There are two types of laser cutters: CO2 and diode (semiconductor) lasers. This makes the modification mainboard independend, so the laser can be mounted on almost any 3D printer.
The laser circuit is optically sepparated from the 3D printer circuit. Then the laser is connected to the power supply and the mainboard. First, the nozzle is replaced by a laser, using a self-made 3D printed holder. It can be done by anyone who has assembled a 3D printer. The omission of these parts made it possible to choose the slightly more expensive 5500mW laser, instead of the 2500mW laser.Ĭonverting the 3D printer to a laser cutter is relatively easy. The 3D printer already contains a 12 Volt power supply and the laser is controlled by the mainboard of the printer. The used materials may not be too hard (metal), too transparent (plastic) or too thick (> 3 to 5 mm). This makes it possible to cut or engrave cardboard, fabric and wood.
And it is not necessary to read the previous parts. This project starts with a working 3D printer. And this time I've altered the 3D printer into a laser cutter. This is the third Instructable with the Anet A8 3D printer. And this is also documented in a previous Instructable. I've already attached a dremel to the Anet A8 3D printer. In addition to a 3D printer, it can be useful to use a CNC machine or a laser cutter. And after a few improvements, this printer gives a nice result. In a previous instructable I've assembled and improved an Anet A8 3D printer. The big advantage is that you can design and make your own 3D objects. Most of my DIY projects make use of a 3D printer.
