|---|---|---|
| Market snapshot | ||
| Listing priceUSD/kg; dated snapshots | $102.50/kg median; $47.00–$166.67/kg across 4 dated product listings | Not documented |
| Identity & Market | ||
| Base polymer / chemistry | ABS compounded with a conductive carbon filler for static-dissipative parts[1] | Aramid-fibre reinforced polyamide[2] |
| Densityg/cm³ | 1.09 (ISO 1183)[1] | Not documented |
| Typical priceUSD/kg | 1 kg-equivalent spools span 47–167; the middle of the market is about 103[3][4][5] | Not documented |
| Price range across brandsUSD/kg | 47–167 across brands; IEMAI 47, YXPOLYER 65, 3DXTech 140 at 750 g pricing; the EMI-shielding ABS grade runs 167[3][4][5] | Not documented |
| Market availability1–5 | Niche, a handful of specialist brands[3] | 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[6][3] |
| Spool sizes & diameters | 1.75 and 2.85 mm; 750 g spools[3] | Not documented |
| Typical applications | Electronics handling fixtures, trays and jigs used around static-sensitive parts[1] | Not documented |
| Printing Parameters | ||
| Enclosure / chamber requirement1–5 | Enclosure recommended[7] | 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[7][8] | Not documented |
| Warping tendency1–5 | High — enclosure needed for reliable large parts[7] | Not documented |
| Bed-adhesion difficulty1–5 | Needs a specific surface plus adhesive[7] | Not documented |
| Stringing / oozing tendency1–5 | Slight — Polymaker advises 1–2 mm retraction at 20–30 mm/s[9] | Not documented |
| Overall printing difficulty1–5 | Intermediate — dry filament and a tuned profile[7] | Not documented |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Hardened steel required[1] | Hardened steel required — no aramid-filled nylon datasheet was obtainable; Polymaker measures about 9 h of brass nozzle life on its fibre-filled nylons[10] |
| Abrasiveness1–5 | Moderately abrasive — conductive carbon filler[1] | Highly abrasive — fibre-reinforced nylon composite[10] |
| Nozzle clog risk1–5 | Low — 3DXTech lists no special nozzle concerns and no minimum layer height for its ESD-ABS, only an 80 °C pre-dry[11] | 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[12] |
| Heat-creep / jam sensitivity1–5 | Slightly sensitive[8] | Not documented |
| Hotend requirement | No special hot-end required[8] | 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[13][14][11] | Very high (>2 %) — the polyamide matrix governs uptake[15] |
| Symptoms when wet | Bubbling and popping at the nozzle, stringing and a rough surface[15] | 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[15] | 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[16][17] |
| Storage requirement | Sealed with desiccant; Polymaker rates ABS moderate-sensitivity[15] | Not documented |
| Mechanical Properties | ||
| Tensile strength (XY)MPa | 58 at break (printed XY, ISO 527) — the conductive filler raises strength above the unfilled grade's 42[1][18] | Not documented |
| Young's modulusMPa | 2130 (printed XY, ISO 527)[1] | Not documented |
| Elongation at break% | 4 at break (printed XY, ISO 527)[1] | Not documented |
| Flexural strengthMPa | 80 (printed XY, ISO 178)[1] | Not documented |
| Flexural modulusMPa | 2275 (printed XY, ISO 178)[1] | Not documented |
| Brittleness1–5 | Moderate[1] | Not documented |
| Creep resistance / sustained load1–5 | Moderate — no creep test found; Tg of 105 °C keeps room-temperature service far below softening[1] | Not documented |
| Fatigue / repeated-flex resistance1–5 | Below average — no S-N curve found; elongation at break 4 %, well below unfilled ABS[1][18] | Not documented |
| Elasticity / flexibility1–5 | Rigid[1] | Not documented |
| Thermal Properties | ||
| Glass transition (Tg)°C | 105 (DSC)[1] | Not documented |
| Environment & Chemical | ||
| Chemical resistance | Good against weak acids, weak alkalis, oils and grease; dissolved by acetone[19] | Not documented |
| Food contact | Not food safe — Polymaker cites potential chemical leaching[9] | Not documented |
| Biodegradability / compostability | Not biodegradable[9] | Not documented |
| Recyclability | Mechanically recyclable but not accepted in household plastic collection[9] | Not documented |
| Electrical & ESD properties | Surface resistance 10⁷–10⁹ ohm/sq, the static-dissipative band (ASTM D257), against above 10¹³ for unfilled ABS[1][18] | Not documented |
| Health & Safety | ||
| Fume toxicity1–5 | High — hazardous VOC such as styrene; enclosure and filtration needed[20][7] | Moderate — measurable VOCs and UFPs, ventilation advised[20] |
| VOC emission rateµg/min | 12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[20] | Up to 180 caprolactam, the dominant VOC from nylon and the largest single-VOC rate in the study[20] |
| Ultrafine-particle emission rateparticles/min | 2 × 10¹⁰ to 9 × 10¹⁰ median across all ABS printers, two orders of magnitude above PLA's ≈1 × 10⁸[20] | ≈2 × 10⁸ median for nylon — low for particles despite the highest VOC mass measured[20] |
| 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[20][7] | Caprolactam, at up to 180 µg/min from nylon filament[20] |
| Ventilation / filtration requirement1–5 | Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[20][7] | Ventilated room or enclosure recommended[20] |
| Dust & fibre handling hazard | Conductive carbon filler is bound in the matrix; avoid inhaling sanding dust[1] | Not documented |
| Post-Processing | ||
| Sanding & machining | Sands well and takes filler before painting[9] | Not documented |
| Painting & finishing | Paints readily after light abrasion[9] | Not documented |
| Support material pairing | HIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[21][7] | Not documented |
| Solvents & Solubility | ||
| Soluble in | Acetone dissolves it — the basis of ABS slurry; so do MEK, THF, ethyl acetate, chloroform, dichloromethane and toluene.[22][19] | Formic acid, phenol, m-cresol and hexafluoroisopropanol dissolve the matrix at 23 °C, leaving the fibre; laboratory reagents.[23] |
| Softened or crazed by | Petrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[22][24] | Zinc chloride solutions stress-crack the nylon matrix, alcoholic calcium chloride dissolves it, mineral acids attack it.[23] |
| Solvent welding & smoothing agent | Acetone: about 20 min of vapour at 80 °C over 5 mm of liquid. Prusa measured layer adhesion more than doubled.[25] | None — nylon's only solvents (formic acid, phenol, HFIP) degrade the part, and the fibre blocks surface flow anyway.[23] |
