- −153x77mm plate is tight for anything larger than small character models
- −Still needs a wash and cure station: budget $50-80 extra
Prusa Core One
- +Prusa reliability is not marketing. It's earned over years.
- +55C active chamber heating handles demanding materials
- +Fully open-source, no vendor lock-in anywhere
- −The assembled price is hard to justify against the Bambu alternatives
- −Build volume is smaller than what you'd expect at this price
