Printing with PETG and PVA as a support material

Recommended Posts

Posted · Printing with PETG and PVA as a support material


  I'm trying to print with Polymaker's PETG and use UM PVA with the BB 0.4  printcore for the support.  I'm using Cura 5.0.0 and the default profiles for both.  I have dried my unopened pack of PVA for 10 hours in my dehumidifier at 45°C.  The model is an anamorphic text of two names on a flat base, morphing from one name into the other at 90°.  The support isn't touching the glass, but only where needed under the letters.  The PVA isn't adhering to the PETG and builds up around the nozzle, before I cancel the print.  I have printed the sample dimensional accuracy model tower in only PVA and it prints great by itself.  My problem is the interface between both materials. Does anyone have any ideas to make this work for me?  The two materials are supposed to be compatible.


  I have tried the Breakaway material as well, but it's not much easier to remove than the PETG generated support from the one printcore.  I'd love to print more of these nameplates, but the clean up is just far too much hassle.

    Not every PETG is the same. Ultimaker PETG works pretty well with PVA, others might not work at all. Aquasys 120 certainly offers a wider range, but also BVOH might be worth to have a look at with PETG.

      • UltiMaker Cura 5.3 stable released
        In this stable release, Cura 5.3 achieves yet another huge leap forward in 3D printing thanks to material interlocking! As well as introducing an expanded recommended print settings menu and lots of print quality improvements. Not to mention, a whole bunch of new printer profiles for non-UltiMaker printers!

      • UltiMaker Cura Alpha 🎄 Tree Support Spotlight 🎄
        Are you a fan of tree support, but dislike the removal process and the amount of filament it uses? Then we would like to invite you to try this special release of UltiMaker Cura. Brought to you by our special community contributor @thomasrahm
        We generated a special version of Cura 5.2 called 5.3.0 Alpha + Xmas. The only changes we introduced compared to UltiMaker Cura 5.2.1 are those which are needed for the new supports. So keep in mind, this is not a sneak peek for Cura 5.3 (there are some really cool new features coming up) but a spotlight release highlighting this new version of tree supports.
