Does anyone here have experience with large format 3D printers like the Cincinatti BAAM at ORNL or the Thermwood LSAM? I've been working with smaller scale 3D printers for years, and have been keeping myself up to date with the desktop market, but I haven't come across many discussions about the super large scale 3D printers, especially anything getting into the more technical aspects of their workings. These machines look pretty awesome from the marketing videos on youtube, but I'm curious what they're really like to program and operate when the cameras are off. I know I've had my share of print failures on a much smaller machine, and there's been a ton of work that's gone into software and hardware to get printing to the level its at now. I'd love to get a conversation going about what it takes to print the kind of large parts these machines are capable of, especially around the use of screw extruders and pellets instead of using filament like all smaller FDM machines are using.
