What are you guys using as support filament for PEBA?
I don’t know how it will work but I was planning on trying pva
Im not a fan of PVA, I was looking for breakaway supports. I guess I will run some tests myself to figure it out. The candidates are:
- ABS - since its nylon based
- Support for PA (as a side note bambu has discontinued it)
- Support for ABS (HIPS)
- PC
Just finished printing a basketball in Sainsmart 90A PEBA using BBL PVA normal supports & it worked a treat. For the PEBA, I increased the max volumetric speed to 6mm/s, absolutely no stringing & the print was clean.. The PVA was dried for 18hrs & did start to ‘Pop’ slightly towards the end of printing support but the H2C cleaned the left nozzle periodically which prevented any problems. I left the model to soak in a bowl of warm water for 30mins after which I removed some of the supports manually, another few hours & the rest had dissolved. Needed to change the water a few times to speed up the process. In sum, I’ll be using PVA again!
P2S won’t feed PEBA - I have tried everything, Dried the Sainsmart 90A for 2 days, changed the nozzel to a .6, Cut the fillament at a sharp angle, preheated the nozzel and manually directly fed from the top and it just wont feed. It grabs and lowers when I push the button to feed but stops at the head. TPU feeds np. Please give me some suggestions.
I am placing a second vote for PLA, but you might have to mess around with the print variables.
Would have tested pla first as well… usually the plastic that sticks to the least amount of other plastics.
HIPS would have been the second choice.
ABS might work, but expect issues with running the chamber cold (assume similar settings to tpu?)
PVA provides excellent results when printing supports for PEBA & TPU. However, the supports must be made entirely of PVA, not just the interface layer.
