Typical priceUSD/kg1 kg-equivalent spools span 22–125; the middle of the market is about 36[3][4][5][6][7]Not documented
Price range across brandsUSD/kg22–125 across brands; IEMAI 22, Siraya Tech 28 and 36 for the core-shell grade, YXPOLYER 35, Push Plastic 50 at 2 kg, 3DXTech 64 at 750 g; Stratasys-compatible cartridges run far higher[3][4][5][6][8][7]Not documented
Market availability1–5Available from several mainstream brands[3][4]Not documented

Typical applicationsStiff tooling and fixtures that must survive above 100 °C[1]Manufacturer applications include footwear, sports equipment and cushioning.[2]
Printing Parameters
Nozzle temperature°CNot documented230–260 °C; 240 °C recommended.[2]
Bed temperature°CNot documented60–90 °C[2]
Enclosure / chamber requirement1–5Enclosure recommended[10]Not documented
Part cooling fanNot documented10–50% fan recommended; mechanical-test specimens used 50–100%.[2]
Bed surface & adhesion aidClean the plate and apply glue; Simplify3D also lists Kapton tape and ABS slurry[10][11]PEI build plate[2]
Maximum volumetric flow (mm³/s; see test conditions)mm³/sNot documented9 mm³/s maximum in eSUN spiral-vase test; mechanical specimens used 2 mm³/s. Linear recommendation 25–110 mm/s is a separate quantity.[2]
Warping tendency1–5Moderate — needs adhesion aid or draught shield; the fibre reduces warping against unfilled ABS[10]Not documented
Bed-adhesion difficulty1–5Needs a specific surface plus adhesive[10]Not documented
Stringing / oozing tendency1–5Slight — Polymaker advises 1–2 mm retraction at 20–30 mm/s[12]Not documented
Overall printing difficulty1–5Intermediate — dry filament and a tuned profile; hardened nozzle mandatory[10]Not documented
Hardware Wear & Reliability
Nozzle hardness required1–4Hardened steel required[10]Not documented
Abrasiveness1–5Highly abrasive — standard CF composite[10]Not documented
Nozzle clog risk1–5Moderate — needs dry filament and a clean nozzle; 3DXTech specifies a hardened nozzle of 0.4 mm minimum and 0.25 mm layers or higher, and Prusa lists composites as a higher clogging risk[13][14][15]Not documented
Heat-creep / jam sensitivity1–5Slightly sensitive[11]Not documented
Hotend requirementNo special hot-end required[11]Not documented
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5Moderate — the ABS matrix takes up 0.51–0.65 % saturated at 25 °C / 55 % RH and 3DXTech specifies a 80 °C, 4 h pre-dry[16][17][13]Not documented
Drying temperature & timeNot documented70–75 °C for 6–8 h; re-dry after receiving or extended exposure.[2]
Symptoms when wetBubbling and popping at the nozzle, stringing and a rough surface[18]Not documented
Effect of moisture on strengthPolymaker rates ABS moderate-sensitivity and publishes no dry-versus-conditioned figures; absorbed water flashes to steam in the hotend and shows as bubbling and poor layer adhesion[18]Not documented
Storage requirementSealed with desiccant; Polymaker rates ABS moderate-sensitivity[18]Not documented
Mechanical Properties
Tensile strength (XY)MPa46 at break (printed XY, ISO 527)[1]>16.5 MPa printed XY, GB/T 1040; manufacturer lower bound, not an exact measurement.[2]
Young's modulusMPa5210 (printed XY, ISO 527) — more than double unfilled ABS[1]Not documented
Elongation at break%2 at break (printed XY, ISO 527)[1]>520% printed XY, GB/T 1040; manufacturer lower bound.[2]
Flexural strengthMPa76 (printed XY, ISO 178)[1]Not documented
Flexural modulusMPa5260 (printed XY, ISO 178)[1]Not documented
Layer adhesion / Z tensileMPaNot documented7.5 MPa printed Z, GB/T 1040 (manufacturer test)[2]
Brittleness1–5Brittle — snaps with little warning; elongation at break 2 %[1]Not documented
Hardness (scale-specific)Shore A / Shore D / RockwellNot documented90 Shore A nominal grade designation; do not compare numerically with Shore D or Rockwell.[9]
Creep resistance / sustained load1–5Good — no creep test found; chopped carbon fibre restrains matrix flow and modulus rises to 5210 MPa against 2200–2330 for unfilled ABS[1][16][17]Not documented
Fatigue / repeated-flex resistance1–5Below average — no S-N curve found; elongation at break falls to 2 % against 10.5 % for unfilled ABS[1][16]Not documented
Elasticity / flexibility1–5Rigid[1]Not documented
Thermal Properties
Glass transition (Tg)°C105 (DSC)[1]Not documented
Melting point / Vicat°CNot documented110 °C Vicat softening (GB/T 1633, 120 °C/h, 10 N); not HDT or a continuous-use rating.[2]
Thermal expansion (CTE)µm/m·K19–25 along the print bead and 80–84 in the build direction at 30 °C (20 wt% CF, large-format printed, TMA)[19]Not documented
Environment & Chemical
Chemical resistanceGood against weak acids, weak alkalis, oils and grease; dissolved by acetone[20]Not documented
Food contactNot food safe — Polymaker cites potential chemical leaching[12]Not documented
Biodegradability / compostabilityNot biodegradable[12]Not documented
RecyclabilityMechanically recyclable but not accepted in household plastic collection[12]Not documented
Electrical & ESD propertiesSurface resistance above 10⁹ ohm/sq — not static-dissipative (ASTM D257)[1]Not documented
Health & Safety
Fume toxicity1–5High — hazardous VOC such as styrene; enclosure and filtration needed[21][10]Not documented
VOC emission rateµg/min12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[21]Not documented
Ultrafine-particle emission rateparticles/min2 × 10¹⁰ to 9 × 10¹⁰ median across all ABS printers, two orders of magnitude above PLA's ≈1 × 10⁸[21]Not documented
Hazardous species emittedStyrene dominates. Bambu Lab states ABS and ASA release harmful gases such as styrene at printing temperature, which can be toxic and cause dizziness or nausea[21][10]Not documented
Ventilation / filtration requirement1–5Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[21][10]Not documented
Dust & fibre handling hazardCarbon fibre is bound in the matrix; sanding dust should not be inhaled[1]Not documented
Post-Processing
Sanding & machiningSands well and takes filler before painting[12]Not documented
Painting & finishingPaints readily after light abrasion[12]Not documented
Vapour / chemical smoothingAcetone smoothing is blunted by the fibre — only the resin fraction dissolves[20]Not documented
Support material pairingHIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[22][10]Not documented
Solvents & Solubility
Soluble inAcetone dissolves the resin and leaves the fibre as sludge; MEK, THF, ethyl acetate and chlorinated solvents do the same.[23][20]Not documented
Softened or crazed byPetrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[23][24]Not documented
Solvent welding & smoothing agentAcetone vapour reaches only the resin fraction, so the fibre is left standing proud of the smoothed surface.[25][20]Not documented

Material entries describe families or representative grades, not an interchangeable specification for every spool. Test methods, orientations and conditions may differ. Unknown values are marked “Not documented”. Prices and source dates remain historical snapshots; check the linked guide for product details. Differences highlight text, not a universal winner.
