MMU3 and Support Materials
I've purchased the MMU3, and during the extensive amount of time waiting for it be shipped I've begun to ponder the possibilities of support material. PVA is available for PLA, without actually knowing if it would work well the MMU3. Though I don't really care because I prefer PETG for its stronger physical properties. Apparently PVA doesn't work well PETG. From what I understand BVOH is the way to go for PTEG. I'm curious to know if BVOH would work well PETG on the MMU3. How about also the added element of using it on MKS3.5. Another observation regarding BVOH is its price: rather expensive. With this being said, it's also as almost as difficult to locate as an organ donor. WTF. F is for fun times finding it. What's going with this stuff, anyone know? My eyes are slowly rolling into the back of head waiting my Prusa oder. I hope to be conscious when it arrives.
Looks promising; need to investigate.
I came across the following from Keene Village Plastics in the United States. Perhaps it's a hybrid, not really sure because they don't refer to the materials type. It's "just" $100 a kilo, versus $75 for 1/2 kilo of BVOH on the PRUSA website.

What's cool about it is the nozzle temp 205-240, very comparable with PTEG. Bed temp 50-90. If this can feed through PFTE tube without breaking, this may be a viable solution. Will likely call them this week and check it out.
The following are material specs.
