Ultimaker PVA Explained – Water-soluble support material

This model is printed using Ultimaker PVA
and PLA in dual extrusion. Let’s take a closer look at how PVA
works with Ultimaker 3. PVA is a support material
that dissolves in water. It’s printed using dual extrusion
on the Ultimaker 3. It is ideal for printing complex geometries
that require support for large overhangs, deep internal cavities
and intricate structures. With PVA support material, models like this gyro
can be printed in place without any post-printing assembly. Traditional methods won’t allow
for this kind of production. Cura automatically identifies which part
of your model requires PVA support. PVA fully supports the print – right from
the bottom of the model to the narrowest cavities. With its great thermal stability, Ultimaker PVA
is more resistant to degradation which guarantees a better print quality
for longer periods of time. Once the print is finished,
simply place it in water to dissolve the PVA. You won’t need any harmful chemicals, as the material
completely dissolves in tap water alone. The PVA is also completely bio-degradable. Once the PVA has dissolved, rinse the model and let it
airdry before doing any additional post-processing. The Ultimaker 3 can print PVA
in dual extrusion with both PLA and Nylon. This means you can create complex,
aesthetically appealing models with PLA and durable, functional prototypes
with an engineering material like Nylon. PVA support enables designers and engineers
to approach the process in a completely new way making it possible to create even more
complex designs with the Ultimaker 3.

  1. What is the NFC feature for on the spool holder for? Does this lock us in to your filaments or can we still use whatever 3rd party filament we want?

  2. How can you print the black and green drill with two colors when appears that it would require support material thus making two colors impossible? The only way I can see doing it would be to print it in two or more pieces and then assemble it. Is that correct?

  3. I use the Ultimaker 3 Extended now for about 2 weeks.
    With 2 color PLA prints I am very satisfied, but with PVA support material I have only chaos.
    As I see it, the problem is that the PVA is not adhering to the PLA "stripping tower". Generally, I find the adhesion of PVA to PLA on my printer is not good.
    Do you have an idea where the problem could be?

  4. will this water solutable pva disolve by epoxy?

    I want to print things that I cover in carbon fiber. Then remove the form with water if possible

  5. in my version of ultimaker cura 3.0.4 pva's profile does not come as material … can someone tell me what parameters he uses ????
    I'm trying to print but I have to go up temperature (265ºC) and put very slow so that it is well founded
    Some help???

  6. Personally I think you should have the setting of creating your own barriers around your plastics with pva instead of using a leap of faith. I want to create very complex sword designs, and so I want to make them crate style using PVA as a box to ensure my print doesn't come out looking jacked and jagged. I'm not big on supports, I'd rather use it for a loot box feeling.
