Is it for me?
- PrimaSELECT PVA+ (polyvinyl alcohol) is a water soluble material that´s most often used as a support material.
- PVA prints translucent with a slightly yellow tint.
- 3D Prima's new formula for PrimaSELECT PVA+ is more stable to print with than regular PVA. This also means that it bonds much better than regular PVA to PLA, ABS and PETG.
- Tested and recommended as soluble supports for our Multi Material upgrade.

- Use PVA filament settings.
- Keep PVA dry, ideally in box with silica gel.
- Nozzle temperature: 205-210 °C
- Bed temperature: 50-60 °C (Bigger object bigger temp.)
- Cooling: none
- Surface preparation: Make sure the surface is clean.

I use this material on Prusa Mini's, not in a multimaterial printer. My application is the creation of water-soluble jigs. I had good results with this material, and thought my notes may be useful: -I start with the Prusa profile 0.15mm quality & PVA, usually with brim -you NEED to store this dry. Material quality will degrade when left open to room air. The material becomes too soft to print when it absorbes moisture. Drying in an oven does work & restores the material. -the material is softer than PLA. If the extruder wheel bites into the filament I loosen the spring 1 or 2 turns vs my PLA-settings. -the material is temperature sensitive. If it is a sunny day and the room gets hot the material gets too soft to print. -fan speed has a pronounced affect on layers that do not take a lot of time. Eg a hollow cylinder OD5mm ID 3.6mm --> in Cooling settings I slow down to 5mm/s and use 20-50% of fan. Slowing down works better than adding more fan. -For some but not all prints I slow down the print. I print at 0.15 layer, 25mm/s perimeter speed and 10mm/s for first layer, bed temp 70 degrees. Like the material a lot, but others seem to have a hard time with it. best -Lieven
Complete trash. Its too stiff and brittle to go in and out of the MMU. Dont waste your time or money on this stuff. I now have 3 unopened boxes of this junk.....
After 3 days of near non-stop Slicer changes, Prusa Support, MMU calibration and general frustration, I'm chalking this one up to a loss; a very expensive and disappointing loss! Prusa support was patient and delightful, they walked me through how I could go about solving my failures. Sadly none of their proposed solutions worked. Let's talk about what goes wrong: Whenever the material loads into the MMU, the idler gears, regardless of tension grind the filament down 'till there's nothing left to pull. It doesn't matter how much, or how little tension is applied to the selector of my MMU, the result is always the exact same, shredded filament. I've gotten plenty of successful MMU prints in PLA, it's not that my unit doesn't work well for other materials. The only reason I'm giving this 2 stars instead of one is because it really does melt well in water. If you have the patience to manually unload and reload this filament for whatever ungodly reason, then by all means give it a shot. If by some miracle I'm able to get this material working, I'll revise my review. For now, I hope you avoid repeating my expensive mistake.
