Hi,
I’d like to ask what material you would recommend as a contact/interface material when printing with ASA? The support itself will be entirely made from ASA—that’s probably the quickest solution—but what material would you use for the final contact layer?
PETG comes to mind, but I’m worried it might stick too much to the ASA.
I tried PETG and PVA first, but with a chamber temp. of 60-65°C id didn’t work that well. I then tested the support material for ABS and ASA form BL and it’s fantastic. I won’t use anything else for these materials. Give it a try!

“Support for ABS” (HIPS) works the best as breakaway supports for ABS and ASA. You can also use PA6-GF or PAHT-CF (Nylon) as it does not bond to ABS or ASA.

Hands down HIPS. The slicer will whine about printing medium temp filaments with high temp, but you can just ignore it.
Here is the exact stuff I’m using, and I just use BL studio default ‘generic HIPS’ profile.

Using PAHT-CF as a support material works, but it’s an unnecessary waste of a high-performance and expensive filament.
A more suitable and cost-effective option is Bambu Lab’s Support for ABS, which delivers clean results and performs reliably.

I bought some HIPS, set it to „Support for ABS“ from Bambu in the AMS and printed ASA some days ago. Worked perfectly on H2D

Similar filament is ABS

I thing i buy HIPS and try
VXL90 for more demanding prints -
HIPS has worked great except when printing SirayaTech ASA-GF. Hips will not stick to it at all and the prime tower and interface layers turn into a spaghetti mess. PETG has worked with SirayaTech ASA-GF but is much harger to remove than I’d like. 3DO ASA-GF and other ASA filaments have worked well with HIPS for me.
I would not even mess with HIPS as it has too many issues sticking to different brands and types of ASA. It was mostly a spaghetti disaster is used as the interface layer. I switched to a spool of Bambu PA6-GF that I had and it works flawlessly! Night and day difference. Don’t even question the cost difference and save yourself the headache of trying to get HIPS to work reliably with ASA. I’ve mainly been using PA6-GF as the support interface layer when printing ASA-GF filaments from 3DO and SirayaTech.

I’ve never had a single issue using HIPS as an interface layer with any type of ASA on my x1c, H2D and H2S.
Are you using any ASA-GF filaments with HIPS? Wondering if the GF variants are more of the issue since that’s the only type of ASA I’ve used with a different support interface materials.
I have used HIPS with ASA and ASA-CF .. works just great !
I have a roll of Bambu PA6-GF that won’t stick to a single build plate I have, even with glue. Using it as interface material for ASA is a great solution for an otherwise-useless roll. Thanks for the idea!
I’ve also had good results with “YXPOLYER HIPS” from amazon.
What solution do you use to dissolve?
I don’t, the supports just pull right off. If they are inside the object (like a ball) you will need dissolvable supports.
This is exactly what I use as well.
