DIY used to just be “the way”. Today “the way” is Bambu. But the scene has also grown a lot, so I could see the market size of DIY staying the same or growing, even if its lost a lot of market share.

It's just the difference between having 3d printers as a hobby vs 3d printing as a hobby.

THis is a case of me not knowing and assuming, ha. I remember the peak days of the RepRap scene so I just assumed as that slowed down, the entire thing was dead

I was attending Bay Area Reprap Club meetings in 2010! Got my first printer (Ultimaker V1) in 2011. My how things have changed. We just got a second Bambu H2D Pro at work. Incredible machine.
