Soluble support material choice.

[louis_sckr 0]

Hello community,

I soon need to print a large model which needs soluble support.

Now my question would be if anybody tried Xioneer VXL 70 for PLA/PETG, their BVOH or if its a better choice to use Verbatim/BASF BVOH. I am using an EIBOS Polyphemus material station combined with an UMS3. I will use interface layers to save material & money. I guess 1mm at 0.2mm layerheight are enough for interface layers?

I mainly need to have smooth surfaces which are floating islands. 

From my readings, the UM PVA is a pain to work with, as well as PVA in general. (I dont care how long it takes to dissolve. If it ends up 48h in water so be it). Main goal is to have a good overhang quality for preferably somewhat cheap.

Any help / experience would be appreciated.

 

Thanks a lot in advance!
