A major motivation for me to try dual printing was using soluble support material.
So I ordered a spool of PVA which is soluble in water.
I printed this male side release buckle using PLA as main material and PVA for support and raft.
I used the right extruder (all metal) for the PVA and blue painter's tape on the glass.
The print does not look perfect - but the issue is related to PLA only (my Cura settings for PLA were not right and bad PLA quality).
Actually, the PVA part turned out to be very nice.

Re: Going soluble - printing PVA
So how does it look after dissolving the PVA? How long did it take to dissolve?
Re: Going soluble - printing PVA
The bottom layer (where it stuck to the raft) looks just like a top layer. I let it dissolve overnight. Most of the PVA was still thereQ*bert wrote:So how does it look after dissolving the PVA? How long did it take to dissolve?
but it was quite pulpy so you can easily remove it.
Re: Going soluble - printing PVA
Next time you're dissolving it, put a small aquarium airstone in the container, and a little submersible aquarium heater. Keep the water 80-85F and constantly moving.

Re: Going soluble - printing PVA
Best news I've heard so far about my yet to be installed 2 extruder kit.
Unless it's a flat, supports when used under a curved surface it looks
pretty bad.
Having all 4 sides on curved objects look finished will be a big step forward.
Did you use 100% infill on the PVA?

Re: Going soluble - printing PVA
Where did you get your PVA from? What measures are you taking to keep it from absorbing moisture out of the atmosphere?
