Hey, I know there are several rosin based printers on the market, but the ones that I have seen all use a projector of some sort to do the curing, I am curious if any one knows of a hobby grade printer that prints using a laser exposure rather than projection, it seems that the projector based solution would cost much more to produce, but that is just me.
My design thoughts for the mechanics:
Small voice coils with a relatively long through (like a speaker), D2A converter to apply an analog DC voltage to the coils, a mirror attached to a 2 axis pivot, a push rod attached to the x pivot and Y pivot. as you increase or decrease the x and y voltages you could “point” reflected laser position on the work piece.
I know that this is not the most robust system, nor is it the easiest to build, but I am just curious about opinions, And not to cite buzz words, but I believe there are mems that do such things for steerable lasers.
