SimplyPrint is the better fit for a print farm or any modern fleet, and it's a serious schools platform in its own right, built around real print farms since 2020. It natively runs the printers BuildBee can't (Bambu, Klipper/Moonraker, Prusa, Duet), adds AI failure detection with AutoPrint continuous printing, filament inventory with NFC, a maintenance system, multi-user roles with SSO and native iOS and Android apps, and ships a dedicated education plan with classes and teachers, an Academy for courses and assignments, quotas and district SSO, so a school never has to trade depth for ease of use.
BuildBee is a friendly on-ramp for a single teacher with one or two older USB or OctoPrint printers, and that simplicity is the whole product. Beyond one classroom (Bambu or Klipper machines, multiple teachers, automation, native apps) it runs out of room.
