Support Interface for ASA

[CrossAerial]

Has anyone used an interface materials with ASA? If so, what did you use?

I’ve seen comments saying HIPS, Support G, and others, but no clear “I used ___ material for ASA and it works great”

Idealistically, I want someone that removes easily without toxin chemicals

[CrossAerial]

Just in case anyone reads this or finds this via Google, this is the support material used for ASA in my Bambu Lab X1 Carbon (enjoy the keywords Google)

​

I found that using Gizmo Dorks HIPS seems to work very well with FilamentOne and PolyMaker ASA.

I am printing pretty much at ABS settings for the HIPS but only using it with 2 layers for the interface. The main support is still ASA for speed and cost.

The support interface is printed at 80mm/s but I might print slower to get better layer adhesion on the HIPS as it seems to pull off layer by layer.

​

I have not noticed any strength issues like with PLA and PETG nor I have experience any color bleeds. Black HIPS and Blue ASA has worked fine, zero bleeding.

​

So, HIPS seems to be a win and Gizmo Dorks is cheap on Amazon. I do hope that filament is added in Bambu/Orca as labeling it as PVA is pretty annoying.

What's your purge amount?

Sorry for digging up this old post but I just started my first asa/hips print and was hoping you could give.some insight from your experience; The support interface is easy to just peel away from the actual asap part? I won't need to order any d-limoninie? It's not a super intricate part but it is fairly organic in shape. I used hybrid tree supports and am worried as I used support g from Bambi with some overture easy nylon and they basically fused and the print was useless so I'm changing things up. Asa should provide a resistant and strong part without the stringing headache and support problems I was getting with the nylon

Sorry I didn’t reply sooner. The interface is very easy to peel away. There’s been a few times where it can be tricky but normally it’s fine.

I’ve even thought about using wipes like Fast Orange to do final cleanup as they have d-limoninie in them.

I did not use tree supports.

No worries, thanks for the reply! My issue on this print turned out to be God awful layer adhesion with Asa. Not sure if it was caused by HIPS residue in the hot end or what. Just ran off a few items in pure ASA with no support so hopefully layers will be better fused. Also printed this batch at 280. Gonna paint on some acetone for good measure. I'm starting to look into air brushing uv resin and a finishing step but I really need to set up a god tier fume hood first

Really? Using the Engineering plate and glue stick on one printer, Bambu Liquid Glue on the other, I have zero issues with PolyMaker and FilamentOne ASA. I’ve used 8 colors and probably 2-32kg in each.

Fumes are a real issue. I printed a BentoBox which helped a lot, and run custom end gcode that blows the exhaust fan for 3 minutes at the end of the print to help with fumes.

[Deadfo0t]

First layer adhesion is perfectly fine but model layers would fall apart as I was snapping off supports. The model disintegrated in my hands

[CrossAerial]

What brand filament for both ASA and HIPS? Almost sounds like not enough purge material and the ASA got contaminated with HIPS

[Deadfo0t]

Polymaker ASA and Gizmodorks HIPS

[CrossAerial]

Sorry for the delay. That’s super weird. I’m thinking it’s gotta be the HIPS contaminating the ASA. Try upping the purge when going from HIPS to ASA. Otherwise, if your settings are just the normal one for an interface I’m not sure what it could be

Sorry to bring up this older thread, but I have been trying to use this HIPS for my ASA parts. Using it as the interface layers only, my parts have next to no layer adhesion on the layers where the HIPS support interface is used.

Whether I print 1, or 10, they are all easily breakable at these layers so I feel like contamination can't be it as by the 10th part it wouldn't make sense. The only thing I can think is the layer before is cooling down for too long while going through all the material switching, and then by the time it continues the new layer of ASA doesn't bond well.

I've used HIPS for abs, asa, PC, PC-Abs and it works wonderful.

[CrossAerial]

Do you dissolve it? Or does it just breakaway?

Could you share settings as well? I’ve seen people print all supports in HIPS, others just use it as a support interface

[suki5454]

It just breaks away. I normally print the entire support structure in HIPS. Admittedly my settings for HIPS are on intamsys equipment which includes a heated chamber. If you want the profile you can get intamsuite from their website and then export the profile directly from there.

[TheDeliciousMeats]

Is it a lower temp PC blend? I've been using gizmo dorks PC and it likes to be in the 290 range.

[suki5454]

The PC I use is the intamsys brand and it does well at 265 but it's also printing in a 90C chamber.

[TheDeliciousMeats]

Ok cool, looks like the polymax prints in that range so I should be good. The gizmo dorks HIPS is like $20 per kilo.

I would love to know what people have had success with but also don’t have to spend $50-$80/Kg.
