| Identity & Market | ||
| Base polymer / chemistry | Acrylonitrile butadiene styrene — a styrenic terpolymer with a butadiene rubber phase[1][2] | Polyamide 6, ring-opened from caprolactam — the most hygroscopic of the common nylons[3][4] |
| Densityg/cm³ | 1.04 (Polymaker PolyLite ABS and ABS Pro) to 1.06 (ABS Max), ISO 1183; Bambu Lab 1.05[5][1][6][7] | 1.06 (ISO 1183, 3DXTech iOn PA6 alloy)[8] |
| Typical priceUSD/kg | 1 kg spools cluster near 20[9][10][11][12][13] | 1 kg-equivalent spools span 39–136; the middle of the market is about 104, though budget unfilled PA6 has now arrived at 39[14][15] |
| Price range across brandsUSD/kg | 12–45 across brands; IEMAI 12, SUNLU 12 at a 3 kg minimum, ELEGOO 15 in a 5 kg pack, Polymaker 19, YXPOLYER 20, Bambu Lab 20, Push Plastic 25, 3DXTech 45[9][10][14][16][11][12][13][17] | 39–136 across brands; YXPOLYER 39, 3DXTech iOn Nylon 6 Alloy 104, WearX Nylon 6 136. Unfilled PA6 filament stays rare — most PA6 reaches the market glass- or carbon-filled[14][15] |
| Market availability1–5 | Ubiquitous, every brand and retailer[9][10][14][16] | Niche, a handful of specialist brands[14] |
| Spool sizes & diameters | 1.75 and 2.85 mm; 1, 5 and 10 kg spools[14][16] | 1.75 and 2.85 mm; 500 g and 750 g spools[14] |
| Typical applications | Enclosures, automotive interior parts and tooling that must hold shape above PLA's 55 °C ceiling[1][18] | Wear parts, bushings and gears where PA6's toughness and abrasion resistance matter more than dimensional stability[3] |
| Printing Parameters | ||
| Nozzle temperature°C | 240–270 (Bambu Lab); 245–265 (Polymaker PolyLite)[5][1] | 220–260 (Polymaker); 225–265 (Simplify3D)[3][19] |
| Bed temperature°C | 80–100 (Bambu Lab); 90–100 (Polymaker)[5][1] | 70–100 (Polymaker); 70–90 (Simplify3D)[3][19] |
| Enclosure / chamber requirement1–5 | Enclosure recommended — Polymaker calls a chamber needed at ambient temperature, Bambu Lab requires an enclosed printer and rules out its P1P and A-series machines[1][20] | Enclosure required (passive)[21][3] |
| Recommended chamber temperature°C | 45–60 (Bambu Lab)[5] | Not documented |
| Part cooling fan | 0–80 % (Bambu Lab); off (Polymaker PolyLite)[5][1] | Part cooling fan not required (Simplify3D)[19] |
| Bed surface & adhesion aid | Clean the plate and apply glue — Bambu Lab lists glue as the way to improve adhesion and prevent warping[20] | PEI sheet with a glue stick, or a dedicated adhesive such as Magigoo[19][3] |
| Maximum volumetric flow (mm³/s; see test conditions)mm³/s | 10–16 (PrusaSlicer guidance for ABS/ASA)[22] | Not documented |
| Warping tendency1–5 | High — enclosure needed for reliable large parts; Bambu Lab attributes surface cracking to cooling stress exceeding interlayer adhesion[20] | Not documented |
| Bed-adhesion difficulty1–5 | Needs a specific surface plus adhesive[20] | Needs a specific surface plus adhesive[19][3] |
| Stringing / oozing tendency1–5 | Slight[1] | Moderate — retraction tuning needed[3] |
| Overall printing difficulty1–5 | Intermediate — dry filament and a tuned profile[20][1] | Advanced — enclosure, hardware upgrades, tuning; the filament must be kept dry throughout the print[3][23] |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Brass fine indefinitely[20] | Brass fine indefinitely for unfilled grades[3] |
| Abrasiveness1–5 | Non-abrasive[20] | Non-abrasive when unfilled[3] |
| Nozzle clog risk1–5 | Low — no special hot-end required and clogging is not among the listed drawbacks; Prusa lists no drybox and no hardened nozzle[24][25] | Very high — frequent jams without careful setup; wet nylon pops and cracks in the melt[26][23] |
| Heat-creep / jam sensitivity1–5 | Slightly sensitive[24] | Moderate — good heatbreak cooling needed[19] |
| Hotend requirement | No special hot-end required[24] | May require an all-metal hot end (Simplify3D)[19] |
| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | Moderate — 0.65 % saturated at 25 °C / 55 % RH (Bambu Lab); Polymaker measures 0.51 % maximum uptake for ABS Pro[5][6] | Very high (>2 %) — Polymaker groups nylon with PVA as the most moisture-prone class, and its own PA6-based composites reach 2.35–3.33 % equilibrium[23][27] |
| Equilibrium moisture content at ~50 % RH% | 0.65 saturated at 25 °C / 55 % RH (Bambu Lab); 0.51 maximum (Polymaker ABS Pro)[5][6] | Not documented |
| Drying temperature & time | 80 °C for 8 h (Bambu Lab); 70 °C for 6 h (Polymaker)[5][1] | 100 °C for 8 h (Polymaker CoPA); storage below 20 % RH[21][28] |
| Symptoms when wet | Bubbling and popping at the nozzle, stringing, rough surface and weak layers[23] | Popping and cracking during extrusion, then defects that Polymaker describes as very hard to diagnose[26] |
| Effect of moisture on strength | Polymaker rates ABS moderate-sensitivity and publishes no dry-versus-conditioned figures; the loss appears as poor layer adhesion and surface defects rather than a stated strength delta[23] | Measured dry against wet on printed specimens at 6.16 % moisture (Polymaker CoPA): tensile 78.0 → 34.3 MPa, Young's modulus 2703 → 724 MPa, flexural strength 109.8 → 22.6 MPa, while notched Charpy rises 6.9 → 27.7 kJ/m² and elongation 12.7 → 13.2 %[21][26] |
| Storage requirement | Sealed with desiccant; Polymaker rates ABS moderate-sensitivity and advises periodic drying in humid climates[23] | Sealed below 20 % RH with desiccant; Polymaker says nylon often needs to stay in a dryer while printing[28][23] |
| Hydrolysis at melt temperature | Not documented | Polymaker requires a 100 °C dry for 8 h and storage below 20 % RH; no molecular-weight loss figure is published, and the published wet data is conditioning rather than melt hydrolysis[21][28] |
| Mechanical Properties | ||

| Elongation at break% | 6.7 (ABS Max) to 10.5 (Bambu Lab) at break, printed XY, ISO 527[5][6][7] | 9 at break (printed XY, ISO 527, 3DXTech iOn PA6 alloy); Stratasys FDM Nylon 6 conditioned gives 38 printed XZ against 3.2 in ZX (ASTM D638)[8][30] |
| Flexural strengthMPa | 60 (ABS Pro) to 63 (ABS Max) printed XY, ISO 178; Bambu Lab 62 ± 4; 3DXTech quotes 76[5][6][7][29] | 78 (printed XY, ISO 178, 3DXTech iOn PA6 alloy); Stratasys FDM Nylon 6 conditioned gives 97.2 printed XZ and 82 ZX (ASTM D790)[8][30] |
| Flexural modulusMPa | 1880 ± 110 (Bambu Lab) to 2500 (ABS Max) printed XY, ISO 178[5][7] | 2200 (printed XY, ISO 178, 3DXTech iOn PA6 alloy); Stratasys FDM Nylon 6 conditioned gives 2196 printed XZ and 1879 ZX (ASTM D790)[8][30] |
| Charpy impact, notchedkJ/m² | 10.5 (ABS Max) and 14.5 (ABS Pro) printed XY, ISO 179, notched; PolyLite ABS 18.0 ± 0.9 and Bambu Lab 21.5 ± 2.2[1][6][7][5] | Not documented |

| Layer adhesion / Z tensileMPa | 21.9 (ABS Pro) to 29.7 (PolyLite) printed Z, ISO 527; Bambu Lab 28 ± 2[5][1][6] | 36.5 ultimate and 28.9 at yield printed ZX (Stratasys FDM Nylon 6, conditioned 20 °C / 50 % RH, ASTM D638)[30] |
| Brittleness1–5 | Tough — absorbs impact, yields before breaking[5][1] | Tough — absorbs impact, yields before breaking[3] |
| Hardness (scale-specific)Shore A / Shore D / Rockwell | Not documented | Shore D 86 and Rockwell 85 (108) — the source does not name the scales on extruded unfilled PA66 stock (ASTM D2240, D785); no figure is published for a PA6 filament[31] |
| Creep resistance / sustained load1–5 | Moderate — no printed-ABS creep test found; Tg of 101–126 °C keeps room-temperature service far below softening, unlike PLA[1][6][7] | Moderate[3] |
| Fatigue / repeated-flex resistance1–5 | Moderate — no printed-ABS S-N curve found; 10.5 % elongation and 21.5 kJ/m² notched Charpy give far more cyclic tolerance than PLA[5][32] | Excellent — living hinges viable[3] |
| Elasticity / flexibility1–5 | Rigid[5] | Semi-flexible[26] |
| Z strength as % of XY% | 85 (Bambu Lab, printed Z against XY tensile); 63 for Polymaker ABS Pro[5][6] | 54 (Stratasys FDM Nylon 6 conditioned, ZX against XZ ultimate tensile, ASTM D638); 59 on the yield figures[30] |
| Wear resistance & friction | Not documented | 3DXTech sells a dedicated wear-resistant PA6 grade; abrasion resistance is the usual reason to choose PA6 over PA12[14] |
| Thermal Properties | ||
| HDT at 0.45 MPa°C | 87 (Bambu Lab) to 118 (Polymaker ABS Max), ISO 75 at 0.45 MPa; PolyLite ABS 100[5][1][7] | Not documented |
| HDT at 1.8 MPa°C | 84 (Bambu Lab) to 113 (Polymaker ABS Max), ISO 75 at 1.8 MPa; PolyLite ABS 98[5][1][7] | 93 (Stratasys FDM Nylon 6, conditioned, ASTM D648 at 264 psi)[30] |
| Glass transition (Tg)°C | 101 (PolyLite) to 126 (ABS Max), DSC; 105 quoted by 3DXTech[1][7][29] | 105 (DSC, 3DXTech iOn PA6 alloy)[8] |
| Melting point / Vicat°C | Amorphous — no melting point; Vicat 104 (PolyLite) to 127 (ABS Max), ISO 306[1][7] | Not documented |
| Continuous service temperature°C | 101 measured on a loaded glass-filled ABS bar (My Tech Fun); unfilled ABS is bounded by its 84–98 °C heat deflection[33][5][1] | Not documented |
| Annealing response | Decomposition above 380 °C (PolyLite ABS, TGA)[1] | Not documented |
| Thermal expansion (CTE)µm/m·K | 86 ± 3 at 0° and 89 ± 3 at 90° raster (printed, fibre Bragg grating, 25–50 °C); 82 for a neat large-format bead at 30 °C[34][35] | 81.0 on extruded unfilled PA66 stock (ASTM D696; source states 4.5e-5 in/in/°F); no figure is published for a PA6 filament, and PA6 and PA66 expand almost identically[31] |
| Flammability / UL 94 | Flammable; no UL 94 rating published for standard ABS, though V-0 grades exist[36][5] | Flammable; no UL 94 rating published for the unfilled filament grades surveyed[8] |
| Environment & Chemical | ||
| UV resistance1–5 | Months outdoors before embrittlement[18] | Months outdoors before embrittlement — unstabilised polyamide yellows and chalks under UV[3] |
| Chemical resistance | Good against weak acids, weak alkalis, oils and grease; poor against strong acids; dissolved by acetone[1] | Withstands oils, fuels and alkalis — the usual reason to choose a polyamide[3] |
| Water / humidity resistance in service1–5 | Good — minor absorption[5] | Absorbs water, properties shift — a conditioned part is measurably softer and larger than the same part dry[26][21] |
| Food contact | Not food safe — Polymaker cites potential chemical leaching[18] | Polymaker notes medical-grade variants exist, but standard filament is not food-contact certified[3] |
| Biodegradability / compostability | Not biodegradable[18] | Not biodegradable[3] |
| Recyclability | Mechanically recyclable as resin code 9, but not accepted in household plastic collection[18] | Mechanically recyclable but not accepted in household plastic collection[3] |
| Electrical & ESD properties | Surface resistance above 10¹³ ohm/sq — insulating (3DXTech, ASTM D257)[29] | Not documented |
| Health & Safety | ||
| Fume toxicity1–5 | High — hazardous VOC such as styrene; enclosure and filtration needed[4][20] | Moderate — measurable VOCs and UFPs, ventilation advised[4] |
| VOC emission rateµg/min | 12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[4] | Up to 180 caprolactam, the dominant VOC from nylon; total VOC reached nearly 200 µg/min, the highest of the nine filaments tested[4] |
| Ultrafine-particle emission rateparticles/min | 2 × 10¹⁰ to 9 × 10¹⁰ median across all ABS printers, two orders of magnitude above PLA's ≈1 × 10⁸[4] | ≈2 × 10⁸ median — low for ultrafine particles despite the highest VOC mass of any filament tested[4] |
| 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[4][20] | Caprolactam, at up to 180 µg/min from nylon filament — the largest single-VOC emission rate measured in the study[4] |
| Ventilation / filtration requirement1–5 | Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[4][20] | Ventilated room or enclosure recommended[4] |
| Post-Processing | ||
| Sanding & machining | Sands well and takes filler; the usual preparation before painting[18] | Sands poorly — the toughness makes it gum rather than powder[19] |
| Gluing & solvent welding | Solvent-welds with acetone[1] | Cyanoacrylate; no common solvent welds polyamide[19] |
| Vapour / chemical smoothing | Acetone vapour smoothing works — ABS dissolves in acetone[1] | No practical vapour smoothing[19] |
| Support material pairing | HIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[37][20] | PVA dissolves cleanly against nylon; Polymaker sells a break-away PolySupport for PA12[19] |
| Dimensional accuracy & detail | Warping and cooling-stress cracking are the accuracy limits, not shrinkage of the melt[20] | Parts grow as they absorb moisture after printing; Polymaker declines to publish a standard dimensional allowance because it depends on geometry and infill[26] |
| Solvents & Solubility | ||
| Soluble in | Acetone dissolves it — the basis of ABS slurry; so do MEK, THF, ethyl acetate, chloroform, dichloromethane and toluene.[38][1] | Dissolved at 23 °C by formic acid above ~50 %, phenol, m-cresol, 96 % sulphuric acid or hexafluoroisopropanol — laboratory reagents.[39] |
| Softened or crazed by | Petrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[38][40] | Zinc chloride solutions stress-crack it — 10 % marginal, 37 % not resistant; alcoholic calcium chloride dissolves it.[39] |
| 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.[41] | None — nylon's only solvents are formic acid, phenol and HFIP, all of which degrade the part they wet.[39] |
