What your process engineer actually checks
UV and weather stability you can verify
ASA replaces ABS's butadiene phase with an acrylic elastomer, so parts hold color, gloss, and strength through prolonged sun and weather instead of yellowing and cracking. Every lot ships with drying and extrusion parameters, so meter-scale prints stay dimensionally stable — dial the line in once, reorder the same pellet.

About this product
Caracol ASA is an acrylonitrile styrene acrylate pellet feedstock qualified for Caracol large-format additive manufacturing (LFAM) extruders. It keeps ASA’s defining strengths — UV stability, weather and chemical resistance — at the scale and material cost of pellet extrusion, so outdoor and finished parts hold color, gloss, and dimensions long after standard ABS would chalk and crack. Available unreinforced or glass-fiber reinforced for stiffer, lower-warp large parts.
Why engineers choose Caracol ASA
Four things production teams verify before running ASA on a large-format system.
UV & weather stable
ASA holds color, gloss, and mechanical strength under prolonged sun and weather. Outdoor parts do not yellow, chalk, or embrittle the way ABS does.
Chemical resistance
Resists acids, alkalis, and many solvents — a fit for enclosures, fixtures, and functional parts exposed to fluids and cleaning agents.
Big-part dimensional stability
Every lot ships with recommended drying and extrusion parameters, so meter-scale prints stay dimensionally stable. Dial the line in once, reorder the same pellet.
Glass-fiber option
GF-reinforced ASA raises stiffness and heat deflection and cuts warpage on large flat sections — useful for tooling, molds, and structural fixtures.
How Additive Plus delivers it
Every order ships production-ready — qualified feedstock, parameters, and a datasheet.
Step 01
Source & qualify
ASA sourced and qualified against Caracol’s extrusion testing so the pellet runs on LFAM systems without a re-development cycle.
Step 02
Dry & screen
ASA is hygroscopic. We ship it dry and specify a re-dry schedule so moisture does not surface as bubbling or weak layers on big prints.
Step 03
Verify & document
Each lot ships with a datasheet and recommended drying and extrusion parameters, so you reorder the same behavior — not a new qualification.
Material overview
ASA (acrylonitrile styrene acrylate) is the weather-resistant cousin of ABS. It shares ABS-like printability and mechanical strength but replaces the butadiene phase with an acrylic elastomer, which is what gives ASA its long-term UV and outdoor stability. In pellet form on a large-format extruder, it delivers those properties across meter-scale parts at a fraction of filament cost — the reason it is a common choice for finished outdoor components, design and furniture, and functional tooling.

Common questions
Don't see yours? Email [email protected] — NDA standard, typical reply within 4 hours.
Is Caracol ASA a filament or a pellet material?
Caracol ASA is a pellet (granulate) feedstock for large-format additive manufacturing (LFAM/FGF) extruders, not a filament. Pellets are the same feedstock form used in injection molding, so material cost per kilogram is a fraction of equivalent filament — the reason ASA pellets are practical for meter-scale outdoor and tooling parts. For desktop filament printers, use a spooled ASA product instead.
Why choose ASA over ABS for outdoor parts?
ASA and ABS print and perform similarly, but ASA replaces ABS's butadiene phase with an acrylic elastomer. That change is what gives ASA its long-term UV and weather resistance: outdoor Caracol ASA parts keep color, gloss, and mechanical strength where ABS would yellow, chalk, and eventually crack. If a part lives outdoors or in sunlight, ASA is the safer choice; for indoor parts where UV is not a factor, ABS is a lower-cost alternative.
Does Caracol ASA need drying before printing?
Yes. ASA is hygroscopic, so it absorbs moisture from the air. Caracol ASA ships dry, and we recommend re-drying at roughly 70–80 °C for 2–4 hours before printing if the pellets have been exposed. Skipping drying on large-format prints shows up as steam bubbling, poor layer adhesion, and surface defects. Exact drying values are on the datasheet shipped with each lot.
Is a glass-fiber reinforced ASA available?
Yes. Caracol ASA is available unreinforced or as a glass-fiber (GF) reinforced grade. GF reinforcement raises stiffness and heat deflection and reduces warpage on large flat sections, which helps on tooling, molds, and structural fixtures. Mechanical values differ from the unreinforced grade — ask a materials engineer for the GF datasheet before you design to it.
Which systems is Caracol ASA qualified for?
Caracol ASA is sourced and qualified for Caracol large-format additive manufacturing extruders, so it runs without a fresh process-development cycle. If you run a different pellet extrusion system, contact a materials engineer — we can confirm compatibility and supply recommended drying and extrusion parameters for your setup.
What extrusion temperature and settings does ASA run at?
Caracol ASA typically extrudes in the 230–260 °C range, with a heated, draft-free environment recommended to control warpage on large parts. Because pellet extruders and nozzle sizes vary, the recommended temperature, flow, and layer settings ship with each lot as part of the datasheet — so you reorder the same behavior rather than re-tuning the line.
Can I order a sample before committing to a full order?
Yes. We can supply a sample of Caracol ASA, or run a paid benchmark part, before you commit to a production quantity — paired with a capability call with a materials engineer to confirm the grade, drying, and extrusion parameters for your application. For volume orders or an official purchase order, request a volume quote.
