Just saw this beast and thought it'd be fun to share

Anyone ever thought of doing multiple extrusion?

Hell yes. Dissolvable supports have so much potential

Right? I managed to snag 2kg of PVA for effectively $20!

Currently, I'm working on an enraged rabbit carrot feeder, but it's not the easiest thing in the world to set up and config. Which is the reason I've got it mostly ready to go and still have yet to actually attach it. That and long lengths of PTFE tubing are building up more friction than I'd like

I was in a place where I needed a plug for a mold that I'd need to dissolve. Any idea how well PVA works with epoxy? If you're interested in printing a test piece, we can wrap it in fiberglass and dissolve the core. Would be cool for making composite parts that can't be made with a two part mold.

I haven't tried printing it yet, but I'd be down to try. I'll need to optimize settings for it anyways. It's regular 1.75mm stuff, so easy enough to use
