Market snapshot
Listing priceUSD/kg; dated snapshots$35.99/kg median; $22.00–$125.00/kg across 7 dated product listings$170.36/kg median; $89.99–$796.00/kg across 4 dated product listings
Identity & Market
Base polymer / chemistryABS reinforced with chopped carbon fibre[1]A carbon-filled compound conductive by volume rather than merely dissipative; Proto-pasta's is PLA-based, Recreus's and NinjaTek's are TPU, and add:north's Koltron G1 does not state its base polymer[2][3][4][5]
Densityg/cm³1.11 (ISO 1183)[1]Not documented
Typical priceUSD/kg1 kg-equivalent spools span 22–125; the middle of the market is about 36[6][7][8][9][10]1 kg-equivalent spools span 90–181 for the carbon-filled grades; add:north's Koltron G1 sits far above at 796 because it is sold only in 100 and 250 g coils[11][12][13]
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[6][7][8][9][14][10]90–796 across brands; Proto-pasta conductive PLA 90 at 1 kg, Recreus Conductive Filaflex 160 at 500 g, NinjaTek Eel 181 at 1 kg, add:north Koltron G1 796 at 250 g[11][3][12][13]
Market availability1–5Available from several mainstream brands[6][7]Niche, a handful of specialist brands[11][3]
Spool sizes & diameters1.75 and 2.85 mm; 0.5, 0.75 and 2 kg spools plus Stratasys-compatible cartridges[6][7]1.75 and 2.85 mm; 0.05, 0.1, 0.25, 0.5, 1 and 2 kg spools[11][3][12][13]
Typical applicationsStiff tooling and fixtures that must survive above 100 °C[1]Capacitive touch surfaces, low-current traces, EMI shielding and static-safe fixtures[2]
Printing Parameters
Enclosure / chamber requirement1–5Enclosure recommended[15]Open frame is fine[2]
Bed surface & adhesion aidClean the plate and apply glue; Simplify3D also lists Kapton tape and ABS slurry[15][16]Not documented
Warping tendency1–5Moderate — needs adhesion aid or draught shield; the fibre reduces warping against unfilled ABS[15]Not documented
Bed-adhesion difficulty1–5Needs a specific surface plus adhesive[15]Not documented
Stringing / oozing tendency1–5Slight — Polymaker advises 1–2 mm retraction at 20–30 mm/s[17]Not documented
Overall printing difficulty1–5Intermediate — dry filament and a tuned profile; hardened nozzle mandatory[15]Intermediate — dry filament and a tuned profile[2]
Hardware Wear & Reliability
Nozzle hardness required1–4Hardened steel required[15]Brass acceptable; hardened steel for volume work[2]
Abrasiveness1–5Highly abrasive — standard CF composite[15]Moderately abrasive — conductive carbon filler[2]
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[18][19][20]Low — Proto-pasta states the carbon-filled grade prints on standard PLA settings with no special nozzle required[2]
Heat-creep / jam sensitivity1–5Slightly sensitive[16]Not documented
Hotend requirementNo special hot-end required[16]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[21][22][18]Not documented
Symptoms when wetBubbling and popping at the nozzle, stringing and a rough surface[23]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[23]Polymaker rates PLA low-sensitivity and publishes no dry-versus-conditioned figures; absorbed water flashes to steam and shows as bubbling and poor layer adhesion[23]
Storage requirementSealed with desiccant; Polymaker rates ABS moderate-sensitivity[23]Not documented
Mechanical Properties
Tensile strength (XY)MPa46 at break (printed XY, ISO 527)[1]Not documented
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]Not documented
Flexural strengthMPa76 (printed XY, ISO 178)[1]Not documented
Flexural modulusMPa5260 (printed XY, ISO 178)[1]Not documented
Brittleness1–5Brittle — snaps with little warning; elongation at break 2 %[1]Brittle — snaps with little warning; carbon-black loading at conductive levels embrittles PLA[2]
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][21][22]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][21]Not documented
Elasticity / flexibility1–5Rigid[1]Rigid[2]
Thermal Properties
Glass transition (Tg)°C105 (DSC)[1]Not documented
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)[24]Not documented
Environment & Chemical
Chemical resistanceGood against weak acids, weak alkalis, oils and grease; dissolved by acetone[25]Not documented
Food contactNot food safe — Polymaker cites potential chemical leaching[17]Not documented
Biodegradability / compostabilityNot biodegradable[17]Not documented
RecyclabilityMechanically recyclable but not accepted in household plastic collection[17]Not documented
Electrical & ESD propertiesSurface resistance above 10⁹ ohm/sq — not static-dissipative (ASTM D257)[1]Conductive rather than dissipative — Proto-pasta sells the grade as electrically conductive composite PLA[2]
Health & Safety
Fume toxicity1–5High — hazardous VOC such as styrene; enclosure and filtration needed[26][15]Low hazard — minimal VOC and particle emission; none of these materials was in the chamber study[26]
VOC emission rateµg/min12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[26]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[26]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[26][15]Not documented
Ventilation / filtration requirement1–5Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[26][15]Open a window / occasional ventilation[26]
Dust & fibre handling hazardCarbon fibre is bound in the matrix; sanding dust should not be inhaled[1]Conductive carbon filler is bound in the matrix; avoid inhaling sanding dust[2]
Post-Processing
Sanding & machiningSands well and takes filler before painting[17]Not documented
Painting & finishingPaints readily after light abrasion[17]Not documented
Vapour / chemical smoothingAcetone smoothing is blunted by the fibre — only the resin fraction dissolves[25]Not documented
Support material pairingHIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[27][15]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.[28][25]Chloroform dissolves PLA-based grades, leaving the carbon black; TPU-based grades need DMF, NMP or THF. Laboratory reagents.[29][30]
Softened or crazed byPetrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[28][31]Acetone and ethyl acetate plasticise a PLA-based grade; a TPU-based grade swells in toluene, esters and alcohols.[29][30]
Solvent welding & smoothing agentAcetone vapour reaches only the resin fraction, so the fibre is left standing proud of the smoothed surface.[32][25]None — neither PLA nor TPU has a workshop-safe welding or smoothing solvent.[29][30]

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.
