Bad devices from bad makers are ready to conquer the world!

Soluble support with PVA and BadPrinter2

We tested the PVA material (Polyvinyl alcohol) to create the support for PLA sample object with strong overhangs (an helical object) that normally is in impossible to print.
We want to prove the multimaterial capability of the BadPrinter2.
We used Cura as slicer with our script for double colour that, during the tool change, moves the hotend to a “parking” area and cooldown the unused one to reduce as much as possible the oozing during the next print phase.
The PVA is a very flexi material, so the retraction has to be used with attention; as you can see in the photo, there are a lot of “strings” of material generated during the material change, but the PVA is water soluble and they can be easily removed in the post-processing without impact on the quality of the PLA part.



In the following video you can see the post-processing operation of removing the PVA support by submerging it into cold water. We know that leaving the part in warm water for about 24 hours cause a complete dissolving of the PVA, but we want to show that also after about 30 minutes in cold water the material became slippery enough to remove easily the support at the interface between PVA and PLA.




  1. Bellissimo video di esempio!
    Una domanda, la macchina è in grado di riprendere da dove ha interrotto il lavoro, in caso di mancanza dell’elettricità ??
