Making your own galvos is a huge feat. High quality ones used for laser cutting or etching can cost up to $2k each. I'm guessing they must have needed to hire someone with a background in this area.
Not sure if they needed super high quality galvos since the ones they used in the Form 1 were cheap Chinese light show ones. Still impressive to figure out all the magnetics etc. I wonder if the scanners or laser power are speed limiting for the machine.
>so we went ahead and put a fully assembled Form 2 in a dust chamber for 6 hours.
I am looking forward to see prints from sahara desert too. LP
We took the inspiration from Markus Kayser who built the solar sinter :) One of my favorite projects.
