Build your own 3D printed laser engraver
With the smooth geometry of a classic arcade machine, the Photon Printer 3D printed laser engraver is a tiny technological wonder. Built as a DIY project by New Zealand engineer Stephen Brockett, the fully functional etching machine was put together using selected DVD burner components and just a few purchased items to fill in the gaps that could not be 3D printed at home.
In part, the project was made possible by salvaging the impressive innards of a standard optical drive, but don’t let Stephen’s modesty fool you… there are a lot of other clever design decisions that kept the total build budget at just $20.
“Optical media drives are actually pretty amazing, they have linear rails, stepper motors, lead screws and even end stops inside them… They’re pretty much an entire axis of a CNC machine ready to go!”
Keeping a healthy respect for the laser at the heart of the machine, a number of safety features were built into the Photon Printer. Nifty inclusions made possible by 3D printing like a roller shutter and angled rear vents (to stop reflected laser light escaping) can be seen in the video below.
The whole journey is fully documented on Thingiverse where it has sparked up a spirited discussion from other makers using the detailed instructions and downloadable files to print out their own versions. Perhaps you could even build on this design further using the Ponoko Personal Factory…
