> The software we wrote as an add on to blender takes the data from that 3D model and translates it into an audio waveform. It then plays the audio file out to the printer through the headphone jack in your computer. This waveform drives a pair of electro magnetic mirrors. The higher the volume, the higher the voltage, the more the mirrors move. The purpose of these mirrors is to reflect and control the path of the laser beam. By using the audio waveform generated from the 3D model data to drive the mirrors, we are able to get the laser beam to draw out the shape of the object. That's takes care of the X and Y axes.

I look forward to people doing weird interesting things with this!

I have no idea how lissajous figures could work, but they're cool and in 3d resin print they'd be cooler.
