Prusa XL

yeah the full system with 5 tool changers comes in at $3500.
Josef mentions in the interview with joel, that they've been partnering with e3d - so that's definitely where the tool changer is coming from.

Which is pretty good.

It's an interesting looking machine alright.

One thing I really don't like - it's still got all that printed petg - and on the model in the video I watched, you could see holes in the surface of one of the key y axis brackets.
That's really poor for something at this price point.
You'd have though bvy now they could have bought their own injection moulder and employed somebody to cnc the moulds.

It is good to finally see them upgrading the electronics and the multi segment heatbed is really neat. Apparently it's just cheaper to make tiny beds with lots of thermistors than one big bed.

On the whole it's a nice looking corexy - probably not a patch for a voron for speed, but I can see josef selling a lot of them.

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.
