Prusa XL

The tool changer is not e3d’s design. It’s quite different from e3d’s. “ Our internally developed kinematic coupler mechanism ensures millions of trouble-free tool changes” - Prusa.

Also, Prusa aren’t and can’t go with injection moulding. Firstly it’s core to their whole philosophy to use 3d printed parts. More importantly though, many of their designs require additive manufacturing.

No idea why some people think injection moulding is an improvement over 3d printed parts. A huge amount of my (and others) printer upgrades have been around replacing injection molded or stamped steel parts with better fitting, better designed 3d printed parts.

The heatbed is unlikely to be cheaper than a slab of aluminium. It still requires a large and well machined aluminium carrier (so, like a normal bed, but with loads of machining). It is however, an easy design to power using dc power. That is an important design constraint on a printer designed to be sold internationally and assembled as a kit.
