ASA print settings

ABS reformulated for outdoors — same strength and heat range, but it does not yellow in sun.

Enclosure: Expect warping, splitting layers or failed prints without one.

Bed surface & adhesion

PEI with a hot bed, or ABS/ASA slurry. Brim on anything tall.

Retraction starting points

Low retraction usually suffices; an enclosure also reduces stringing.

Good for

• Outdoor parts — mounts, housings, garden and automotive fittings
• Anything ABS suits that will also see UV

Watch out for

• Same fume and ventilation story as ABS
• Warps at least as much as ABS — an enclosure is not optional
• Costs noticeably more than ABS for the same spool

Problems this material is prone to

Other filaments

These are widely-published starting points for the generic material, not a specification. Individual spools vary by brand, colour and additive package — always defer to the figures printed on your spool.
