The print beds are SINGLE USE injection molded ABS(I think it's ABS, anyhow).
They snap over the heating element and seem to be a gigantic waste of resources. You can tell R&D was pushed to make their machines as profitable as possible by avoiding reusable parts.
You can't refill their spool cassettes either without some RFID hacking.
We have 3 Stratasys printers at work and yeah, you're absolutely correct.
To add, their 'professional' slicer program "Insight" is the most user hostile piece of software I've ever laid my eyes on. Straight out of 1992 levels of awful. The workflow, the UI (if you can call it that), everything.
The other 'user friendly' slicer is "GrabCAD Print", an Apple style piece of garbage. It lacks everything beyond basic functionality, yet lately they've been pumping it full of subscription locked features.
