This is a pretty neat tour of Prusa's printer factory on the Strange Parts channel

They have an absolutely massive 600 printer farm, with the same mk3 and mk4 machines that they sell to customers, which is really impressive.

They do almost everything in-house, including manufacturing the printer mainboards, for faster project planning and turnaround times.

Note - the video is pretty long at about 40 mins!

After watching I'm a little tempted to pick up some prusament filament to support the company, really like how they are supporting local talent.
