|---|---|---|
| Market snapshot | ||
| Listing priceUSD/kg; dated snapshots | $104.00/kg median; $38.99–$136.00/kg across 3 dated product listings | $19.09/kg median; $10.99–$32.16/kg across 10 dated product listings |
| Identity & Market | ||
| Base polymer / chemistry | Polyamide 6, ring-opened from caprolactam — the most hygroscopic of the common nylons[1][2] | PLA compounded with a mineral filler — Fiberlogy names chalk — that scatters light into a diffuse finish[3][4] |
| Densityg/cm³ | 1.06 (ISO 1183, 3DXTech iOn PA6 alloy)[5] | 1.31 (Bambu Lab, ISO 1183) to 1.38 (Fiberlogy PLA Mineral, method not stated) — above plain PLA from the filler[4][3] |
| Typical priceUSD/kg | 1 kg-equivalent spools span 39–136; the middle of the market is about 104, though budget unfilled PA6 has now arrived at 39[6][7] | Mainstream 1 kg spools cluster near 21[8][9][10] |
| Price range across brandsUSD/kg | 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[6][7] | 11–32 across brands; budget house brands 11–19, Fiberlogy PLA Mineral 32[11][9][12] |
| Market availability1–5 | Niche, a handful of specialist brands[6] | Stocked by most mainstream brands[11][10][8] |
| Spool sizes & diameters | 1.75 and 2.85 mm; 500 g and 750 g spools[6] | 1.75 mm; 1 kg spools plus spool-less refills[8][13] |
| Typical applications | Wear parts, bushings and gears where PA6's toughness and abrasion resistance matter more than dimensional stability[1] | Display models and visible parts where a matte, non-reflective finish matters[4] |
| Diameter tolerance± mm | Not documented | ±0.03 (Bambu Lab)[14] |
| Printing Parameters | ||
| Nozzle temperature°C | 220–260 (Polymaker); 225–265 (Simplify3D)[1][15] | 190–230 (Bambu Lab); 190–210 (Fiberlogy PLA Mineral)[4][3] |
| Bed temperature°C | 70–100 (Polymaker); 70–90 (Simplify3D)[1][15] | 35–45 (Bambu Lab); 60 (Fiberlogy)[4][3] |
| Enclosure / chamber requirement1–5 | Enclosure required (passive)[16][1] | Open frame is fine[4][3] |
| Part cooling fan | Part cooling fan not required (Simplify3D)[15] | Fan on; Fiberlogy specifies 75–100 %[4][3] |
| Bed surface & adhesion aid | PEI sheet with a glue stick, or a dedicated adhesive such as Magigoo[15][1] | Cool plate, high-temperature plate or textured PEI with glue (Bambu Lab); smooth PEI, textured PEI or glass (Fiberlogy)[4][3] |
| Warping tendency1–5 | Not documented | None[4] |
| Bed-adhesion difficulty1–5 | Needs a specific surface plus adhesive[15][1] | Sticks to anything[17] |
| Stringing / oozing tendency1–5 | Moderate — retraction tuning needed[1] | Not documented |
| Overall printing difficulty1–5 | Advanced — enclosure, hardware upgrades, tuning; the filament must be kept dry throughout the print[1][18] | Beginner — prints on any machine out of the box[4][3] |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Brass fine indefinitely for unfilled grades[1] | Brass fine indefinitely[19][4][3] |
| Abrasiveness1–5 | Non-abrasive when unfilled[1] | Slightly abrasive — mineral filler pushes density from 1.24 to 1.31–1.38[3][4][20] |
| Nozzle clog risk1–5 | Very high — frequent jams without careful setup; wet nylon pops and cracks in the melt[21][18] | Very low[19] |
| Heat-creep / jam sensitivity1–5 | Moderate — good heatbreak cooling needed[15] | Moderate — good heatbreak cooling needed; PLA softens below 60 °C[22] |
| Hotend requirement | May require an all-metal hot end (Simplify3D)[15] | No special hot-end required[17] |
| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | 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[18][23] | Moderate — 0.40 % saturated at 25 °C / 55 % RH[4] |
| Equilibrium moisture content at ~50 % RH% | Not documented | 0.40 saturated at 25 °C / 55 % RH (Bambu Lab)[4] |
| Drying temperature & time | 100 °C for 8 h (Polymaker CoPA); storage below 20 % RH[16][24] | 50 °C for 8 h in a forced-air dryer, or 60–70 °C for 12 h on an X1 heatbed; Fiberlogy specifies 50 °C for 6 h[4][3][25] |
| Symptoms when wet | Popping and cracking during extrusion, then defects that Polymaker describes as very hard to diagnose[21] | Bubbling and popping at the nozzle, stringing, rough surface and weak layers[18] |
| Effect of moisture on strength | 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 %[16][21] | Polymaker rates PLA low-sensitivity — the loss shows as poor layer adhesion and brittle layers rather than a published strength figure[18] |
| Storage requirement | Sealed below 20 % RH with desiccant; Polymaker says nylon often needs to stay in a dryer while printing[24][18] | Sealed with desiccant below 20 % RH; shelf life at ambient is long[20][17] |
| Hydrolysis at melt temperature | 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[16][24] | Not documented |
| Mechanical Properties | ||
| Tensile strength (XY)MPa | 62 at break (printed XY, ISO 527, 3DXTech iOn PA6 alloy); Stratasys FDM Nylon 6 conditioned to 20 °C / 50 % RH gives 67.6 ultimate and 49.3 at yield printed XZ (ASTM D638)[5][26] | 30 (printed XY, ISO 527, Bambu Lab); 35.1 on My Tech Fun bars for PolyTerra PLA[4][27] |
| Young's modulusMPa | 2110 (printed XY, ISO 527, 3DXTech iOn PA6 alloy); Stratasys FDM Nylon 6 conditioned gives 2232 printed XZ and 1817 ZX (ASTM D638)[5][26] | 1960 (Bambu Lab, printed XY, ISO 527); Fiberlogy PLA Mineral quotes 3500 (ISO 527, specimen type not stated)[4][3] |
| Elongation at break% | 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)[5][26] | 14.8 (printed XY, ISO 527)[4] |
| Flexural strengthMPa | 78 (printed XY, ISO 178, 3DXTech iOn PA6 alloy); Stratasys FDM Nylon 6 conditioned gives 97.2 printed XZ and 82 ZX (ASTM D790)[5][26] | 53 (printed XY, ISO 178) — 30 % below PLA Basic at 76[4][20] |
| Flexural modulusMPa | 2200 (printed XY, ISO 178, 3DXTech iOn PA6 alloy); Stratasys FDM Nylon 6 conditioned gives 2196 printed XZ and 1879 ZX (ASTM D790)[5][26] | 2360 (printed XY, ISO 178)[4] |
| Charpy impact, notchedkJ/m² | Not documented | 6.3 (printed XY, ISO 179, notched); unnotched 19.2[4] |
| Other impact data | Izod notched 106 J/m printed XZ against 43 J/m in ZX; unnotched 2873 against 192 J/m (Stratasys FDM Nylon 6, conditioned 20 °C / 50 % RH, ASTM D256 Method A) — a 15x anisotropy unnotched[26] | Izod 6.1 kJ/m² on My Tech Fun printed bars for PolyTerra PLA[27] |
| Layer adhesion / Z tensileMPa | 36.5 ultimate and 28.9 at yield printed ZX (Stratasys FDM Nylon 6, conditioned 20 °C / 50 % RH, ASTM D638)[26] | 22 (printed Z, ISO 527); flexural Z falls to 29 against 53 in XY; 12.9 on My Tech Fun layer-adhesion bars[4][27] |
| Brittleness1–5 | Tough — absorbs impact, yields before breaking[1] | Brittle — snaps with little warning[4] |
| Hardness (scale-specific)Shore A / Shore D / Rockwell | 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[28] | Not documented |
| Creep resistance / sustained load1–5 | Moderate[1] | Poor — 12 mm bar sagged to 18.7 mm over 5 days at 1.25 kg[27] |
| Fatigue / repeated-flex resistance1–5 | Excellent — living hinges viable[1] | Poor — no grade-specific S-N curve; plain printed PLA ran 38 000–49 000 cycles at 30 % of tensile strength (R = 0.2)[29][22] |
| Elasticity / flexibility1–5 | Semi-flexible[21] | Rigid[4] |
| Z strength as % of XY% | 54 (Stratasys FDM Nylon 6 conditioned, ZX against XZ ultimate tensile, ASTM D638); 59 on the yield figures[26] | 73 by tensile, 55 by flexural (printed, Bambu Lab)[4] |
| Wear resistance & friction | 3DXTech sells a dedicated wear-resistant PA6 grade; abrasion resistance is the usual reason to choose PA6 over PA12[6] | Not documented |
| Thermal Properties | ||
| HDT at 0.45 MPa°C | Not documented | 58 (Bambu Lab) and 48 (Fiberlogy PLA Mineral), ISO 75 at 0.45 MPa[4][3] |
| HDT at 1.8 MPa°C | 93 (Stratasys FDM Nylon 6, conditioned, ASTM D648 at 264 psi)[26] | 52 (ISO 75, 1.8 MPa)[4] |
| Glass transition (Tg)°C | 105 (DSC, 3DXTech iOn PA6 alloy)[5] | 61 (DSC)[4] |
| Melting point / Vicat°C | Not documented | 163 peak melt (DSC); Vicat 63 °C[4] |
| Continuous service temperature°C | Not documented | 54 — loaded bars begin to move at this temperature[27] |
| Annealing response | Not documented | 50–60 °C for 6–12 h; some prints deform or warp, and a forced-air oven is required[4] |
| Thermal expansion (CTE)µm/m·K | 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[28] | Not documented |
| Flammability / UL 94 | Flammable; no UL 94 rating published for the unfilled filament grades surveyed[5] | Flammable; no UL 94 rating published by the major brands[20][30] |
| Environment & Chemical | ||
| UV resistance1–5 | Months outdoors before embrittlement — unstabilised polyamide yellows and chalks under UV[1] | Degrades within weeks outdoors[22][31] |
| Chemical resistance | Withstands oils, fuels and alkalis — the usual reason to choose a polyamide[1] | Good against weak acids, oils and grease; poor against strong acids and alkalis; dissolved by chloroform, THF and hot benzene[30][22] |
| Water / humidity resistance in service1–5 | Absorbs water, properties shift — a conditioned part is measurably softer and larger than the same part dry[21][16] | Good — insoluble in water[20] |
| Food contact | Polymaker notes medical-grade variants exist, but standard filament is not food-contact certified[1] | Base resin is food-contact grade, but printed layer grooves harbour bacteria; Prusa advises against food use[22] |
| Biodegradability / compostability | Not biodegradable[1] | Industrially compostable only — needs sustained 55 °C; not home compostable[32][22] |
| Recyclability | Mechanically recyclable but not accepted in household plastic collection[1] | Mechanically recyclable; not accepted in household plastic collection[32] |
| Health & Safety | ||
| Fume toxicity1–5 | Moderate — measurable VOCs and UFPs, ventilation advised[2] | Low hazard — minimal VOC and particle emission[2] |
| VOC emission rateµg/min | Up to 180 caprolactam, the dominant VOC from nylon; total VOC reached nearly 200 µg/min, the highest of the nine filaments tested[2] | Not documented |
| Ultrafine-particle emission rateparticles/min | ≈2 × 10⁸ median — low for ultrafine particles despite the highest VOC mass of any filament tested[2] | Not documented |
| Hazardous species emitted | Caprolactam, at up to 180 µg/min from nylon filament — the largest single-VOC emission rate measured in the study[2] | Not documented |
| Ventilation / filtration requirement1–5 | Ventilated room or enclosure recommended[2] | None needed in a normal room[2] |
| Post-Processing | ||
| Sanding & machining | Sands poorly — the toughness makes it gum rather than powder[15] | Wet sanding — dry sanding heats the surface by friction and smears it[31][22] |
| Gluing & solvent welding | Cyanoacrylate; no common solvent welds polyamide[15] | Cyanoacrylate for most joints; some grades partially dissolve and bond with acetone[22][33] |
| Vapour / chemical smoothing | No practical vapour smoothing[15] | No practical vapour smoothing — only chloroform, hot benzene or THF, which are laboratory-only[22] |
| Support material pairing | PVA dissolves cleanly against nylon; Polymaker sells a break-away PolySupport for PA12[15] | Support for PLA (Bambu Lab)[4] |
| Dimensional accuracy & detail | Parts grow as they absorb moisture after printing; Polymaker declines to publish a standard dimensional allowance because it depends on geometry and infill[21] | Matte surface hides layer lines; 55° overhangs and 30 mm bridges as for plain PLA[4] |
| Solvents & Solubility | ||
| Soluble in | Dissolved at 23 °C by formic acid above ~50 %, phenol, m-cresol, 96 % sulphuric acid or hexafluoroisopropanol — laboratory reagents.[34] | Chloroform: 10 % w/v in 2–4 h at 23 °C, every grade and morphology; THF and DMF only at 65 °C. Laboratory reagents.[35] |
| Softened or crazed by | Zinc chloride solutions stress-crack it — 10 % marginal, 37 % not resistant; alcoholic calcium chloride dissolves it.[34] | Acetone, ethyl acetate and toluene plasticise it but dissolve <1 % even at 65 °C; submersion in acetone crazes and destroys parts.[35][36] |
| Solvent welding & smoothing agent | None — nylon's only solvents are formic acid, phenol and HFIP, all of which degrade the part they wet.[34] | Chloroform vapour smooths and welds PLA at the cost of tensile strength; acetone does not smooth it at all.[37][36] |
