Help on PVA

[Pietroy 0]

I have to buy an Ultimaker s5 and I would like to print the supports with PVA, on the site I found information that I cannot understand, the information is this: BB 0.4, BB 0.8, are they extruders to be purchased separately or are they other objects? Are they present in the package?

The printer will come with 2 AA 0.4 cores and one BB 0.4 core.

 

The BB core's are for PVA only.  The AA cores are for everything except PVA and abrasive filaments.

 

I recommend avoiding the BB 0.8 core which wastes/uses a lot more PVA (PVA is more expensive).  It's okay to have an AA 0.8 core on the left and a BB 0.4 core on the right.  Cura can handle this no problem.

 

Abrasive filaments should be avoided for people new to 3d printing but include: Cabron filled filaments, Fiberglass filled filaments, Steel filled filaments and glowfill.

 

Most filaments are not abrasive (PLA, TPLA, ABS, Nylon, PP, CPE, PETG, TPU, PVA, PC).
