| Property | Carbon-fibre ABS (ABS-CF)ABS | Aramid-fibre nylonPA |
|---|---|---|
| Market snapshot | ||
| Listing priceUSD/kg; dated snapshots | $35.99/kg median; $22.00–$125.00/kg across 7 dated product listings | Not documented |
| Identity & Market | ||
| Base polymer / chemistry | ABS reinforced with chopped carbon fibre[1] | Aramid-fibre reinforced polyamide[2] |
| Densityg/cm³ | 1.11 (ISO 1183)[1] | Not documented |
| Typical priceUSD/kg | 1 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/kg | 22–125 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 availability1–5 | Available from several mainstream brands[3][4] | Special order, 1–2 makers worldwide — no aramid-filled nylon filament was found in any catalogue searched; the aramid filaments that do exist in the retail market use an ASA matrix[9][3] |
| Spool sizes & diameters | 1.75 and 2.85 mm; 0.5, 0.75 and 2 kg spools plus Stratasys-compatible cartridges[3][4] | Not documented |
| Typical applications | Stiff tooling and fixtures that must survive above 100 °C[1] | Not documented |
| Printing Parameters | ||
| Enclosure / chamber requirement1–5 | Enclosure recommended[10] | Enclosure required (passive) — as for every nylon[2] |
| Bed surface & adhesion aid | Clean the plate and apply glue; Simplify3D also lists Kapton tape and ABS slurry[10][11] | Not documented |
| Warping tendency1–5 | Moderate — needs adhesion aid or draught shield; the fibre reduces warping against unfilled ABS[10] | Not documented |
| Bed-adhesion difficulty1–5 | Needs a specific surface plus adhesive[10] | Not documented |
| Stringing / oozing tendency1–5 | Slight — Polymaker advises 1–2 mm retraction at 20–30 mm/s[12] | Not documented |
| Overall printing difficulty1–5 | Intermediate — dry filament and a tuned profile; hardened nozzle mandatory[10] | Not documented |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Hardened steel required[10] | Hardened steel required — no aramid-filled nylon datasheet was obtainable; Polymaker measures about 9 h of brass nozzle life on its fibre-filled nylons[13] |
| Abrasiveness1–5 | Highly abrasive — standard CF composite[10] | Highly abrasive — fibre-reinforced nylon composite[13] |
| Nozzle clog risk1–5 | Moderate — 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[14][15][16] | High — jams from moisture, heat creep or particles; nylon already needs a drybox and Prusa names kevlar among the fibres that raise nozzle-clogging risk[15] |
| Heat-creep / jam sensitivity1–5 | Slightly sensitive[11] | Not documented |
| Hotend requirement | No special hot-end required[11] | Not documented |
| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | Moderate — 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[17][18][14] | Very high (>2 %) — the polyamide matrix governs uptake[19] |
| Symptoms when wet | Bubbling and popping at the nozzle, stringing and a rough surface[19] | Not documented |
| Effect of moisture on strength | Polymaker 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[19] | Polymaker's printed dry-versus-wet blocks for its CoPA nylon show what conditioning does to the family: tensile 78.0 → 34.3 MPa and modulus 2703 → 724 MPa, with notched Charpy rising 6.9 → 27.7 kJ/m². Fibre reinforcement reduces but does not remove the effect[20][21] |
| Storage requirement | Sealed with desiccant; Polymaker rates ABS moderate-sensitivity[19] | Not documented |
| Mechanical Properties | ||
| Tensile strength (XY)MPa | 46 at break (printed XY, ISO 527)[1] | Not documented |
| Young's modulusMPa | 5210 (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 strengthMPa | 76 (printed XY, ISO 178)[1] | Not documented |
| Flexural modulusMPa | 5260 (printed XY, ISO 178)[1] | Not documented |
| Brittleness1–5 | Brittle — snaps with little warning; elongation at break 2 %[1] | Not documented |
| Creep resistance / sustained load1–5 | Good — no creep test found; chopped carbon fibre restrains matrix flow and modulus rises to 5210 MPa against 2200–2330 for unfilled ABS[1][17][18] | Not documented |
| Fatigue / repeated-flex resistance1–5 | Below average — no S-N curve found; elongation at break falls to 2 % against 10.5 % for unfilled ABS[1][17] | Not documented |
| Elasticity / flexibility1–5 | Rigid[1] | Not documented |
| Thermal Properties | ||
| Glass transition (Tg)°C | 105 (DSC)[1] | Not documented |
| Thermal expansion (CTE)µm/m·K | 19–25 along the print bead and 80–84 in the build direction at 30 °C (20 wt% CF, large-format printed, TMA)[22] | Not documented |
| Environment & Chemical | ||
| Chemical resistance | Good against weak acids, weak alkalis, oils and grease; dissolved by acetone[23] | Not documented |
| Food contact | Not food safe — Polymaker cites potential chemical leaching[12] | Not documented |
| Biodegradability / compostability | Not biodegradable[12] | Not documented |
| Recyclability | Mechanically recyclable but not accepted in household plastic collection[12] | Not documented |
| Electrical & ESD properties | Surface resistance above 10⁹ ohm/sq — not static-dissipative (ASTM D257)[1] | Not documented |
| Health & Safety | ||
| Fume toxicity1–5 | High — hazardous VOC such as styrene; enclosure and filtration needed[24][10] | Moderate — measurable VOCs and UFPs, ventilation advised[24] |
| VOC emission rateµg/min | 12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[24] | Up to 180 caprolactam, the dominant VOC from nylon and the largest single-VOC rate in the study[24] |
| Ultrafine-particle emission rateparticles/min | 2 × 10¹⁰ to 9 × 10¹⁰ median across all ABS printers, two orders of magnitude above PLA's ≈1 × 10⁸[24] | ≈2 × 10⁸ median for nylon — low for particles despite the highest VOC mass measured[24] |
| Hazardous species emitted | Styrene 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[24][10] | Caprolactam, at up to 180 µg/min from nylon filament[24] |
| Ventilation / filtration requirement1–5 | Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[24][10] | Ventilated room or enclosure recommended[24] |
| Dust & fibre handling hazard | Carbon fibre is bound in the matrix; sanding dust should not be inhaled[1] | Not documented |
| Post-Processing | ||
| Sanding & machining | Sands well and takes filler before painting[12] | Not documented |
| Painting & finishing | Paints readily after light abrasion[12] | Not documented |
| Vapour / chemical smoothing | Acetone smoothing is blunted by the fibre — only the resin fraction dissolves[23] | Not documented |
| Support material pairing | HIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[25][10] | Not documented |
| Solvents & Solubility | ||
| Soluble in | Acetone dissolves the resin and leaves the fibre as sludge; MEK, THF, ethyl acetate and chlorinated solvents do the same.[26][23] | Formic acid, phenol, m-cresol and hexafluoroisopropanol dissolve the matrix at 23 °C, leaving the fibre; laboratory reagents.[27] |
| Softened or crazed by | Petrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[26][28] | Zinc chloride solutions stress-crack the nylon matrix, alcoholic calcium chloride dissolves it, mineral acids attack it.[27] |
| Solvent welding & smoothing agent | Acetone vapour reaches only the resin fraction, so the fibre is left standing proud of the smoothed surface.[29][23] | None — nylon's only solvents (formic acid, phenol, HFIP) degrade the part, and the fibre blocks surface flow anyway.[27] |
