| Typical applications | Stiff parts that must stay dimensionally stable in changing humidity — Polymaker sells this grade specifically on low moisture sensitivity[14][1] | Signage, novelty and cosplay parts that glow after light exposure[4] |
| Printing Parameters | ||
| Nozzle temperature°C | 260–290 (Extrudr DURAPRO PA12 CF)[15] | 190–230 on the Bambu Lab TDS against 210–240 in its own material table; colorFabb advises 195–220[4][16][5] |
| Bed temperature°C | 110 (Extrudr DURAPRO PA12 CF)[15] | 35–45 (Bambu Lab); 50–60 (colorFabb)[4][5] |
| Enclosure / chamber requirement1–5 | Enclosure required (passive)[17][1] | Open frame is fine[4] |
| Part cooling fan | Not documented | Fan on; colorFabb allows 0–100 %[4][5] |
| Bed surface & adhesion aid | PEI sheet with a glue stick, or a dedicated adhesive such as Magigoo[18][17] | Not documented |
| Maximum volumetric flow (mm³/s; see test conditions)mm³/s | 12 at Extrudr's 150 mm/s cap on a 0.4 mm nozzle at 0.2 mm layer[15][19] | Not documented |
| Bed-adhesion difficulty1–5 | Needs a specific surface plus adhesive[18] | Not documented |
| Stringing / oozing tendency1–5 | Moderate — retraction tuning needed[17] | Not documented |
| Overall printing difficulty1–5 | Advanced — enclosure, hardware upgrades, tuning[17] | Easy — minor profile tuning; a hardened nozzle is mandatory[16][10] |
| Extruder requirement | Not documented | Bambu Lab: hardened steel and high-flow nozzles only, 0.2 mm excluded, AMS lite not compatible[16] |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Hardened steel required — Polymaker measures brass nozzle life at about 9 h on PA12-CF10 and recommends hardened steel or ruby[1] | Hardened steel required[16][10][5] |
| Abrasiveness1–5 | Highly abrasive — standard CF composite; Polymaker puts brass nozzle life at roughly 9 h on PA12-CF10[1] | Highly abrasive — the phosphor is a hard ceramic; Bambu Lab groups glow with carbon fibre as the materials that wear nozzles and grind AMS PTFE, and both Bambu Lab and Polymaker require a hardened nozzle[16][5] |
| Nozzle clog risk1–5 | High — jams from moisture, heat creep or particles[20] | Moderate — needs dry filament and a clean nozzle[16] |
| Heat-creep / jam sensitivity1–5 | Moderate — good heatbreak cooling needed[18] | Not documented |
| Hotend requirement | May require an all-metal hot end (Simplify3D)[18] | Hardened steel nozzle; Bambu Lab lists glow-in-the-dark among the filaments its hardened-steel nozzle exists for[21][16] |
| Other hardware wear | Not documented | Bambu Lab reports the filament adds enough feeding resistance to fail prints on the AMS lite; colorFabb warns of brass nozzle wear[16][5] |
| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | High (0.8–2 %) — 1.5 % equilibrium, the lowest of Polymaker's nylon composites and less than half its PA6-GF25[1][22] | Moderate — 0.46 % saturated at 25 °C / 55 % RH[4] |
| Equilibrium moisture content at ~50 % RH% | 1.5 equilibrium water absorption (Polymaker Fiberon PA12-CF10)[1] | 0.46 saturated at 25 °C / 55 % RH (Bambu Lab)[4] |
| Drying temperature & time | 80–100 °C; storage below 20 % RH[20][1] | Not documented |
| Effect of moisture on strength | Polymaker's own dry/wet blocks for PA12-CF10 change little: at 2.92 % moisture tensile falls 77.4 → 71.7 MPa and modulus 3311 → 3132 MPa, against a halving for its PA6 grades[1][14] | Polymaker rates PLA low-sensitivity and publishes no dry-versus-conditioned figures for this grade; absorbed water flashes to steam and shows as bubbling and poor layer adhesion[20] |
| Storage requirement | Sealed below 20 % RH with desiccant[20] | Not documented |
| Hydrolysis at melt temperature | Polymaker specifies an 80–100 °C dry and storage below 20 % RH; no molecular-weight loss figure is published, and the wet data it does publish is conditioning rather than melt hydrolysis[23][24] | Not documented |
| Mechanical Properties | ||
| Tensile strength (XY)MPa | 77.4 ± 1.1 printed XY dry (Polymaker Fiberon), 71.7 ± 0.7 conditioned to 2.92 % moisture, ISO 527; 3DXTech quotes 72 at break. Stratasys FDM Nylon 12CF spans 76.5-124 at break printed XZ across five machine and tip combinations (ASTM D638)[1][2][25] | 32 ± 3 printed XY, ISO 527 (Bambu Lab); colorFabb quotes 61.5 by ISO 527 on its own specimens[4][5] |
| Young's modulusMPa | 3311 ± 135 printed XY dry and 3132 ± 124 conditioned, ISO 527 (Polymaker Fiberon); 3DXTech quotes 8000. Stratasys FDM Nylon 12CF spans 7910-15400 printed XZ against 2130-3000 in ZX (ASTM D638)[1][2][25] | 2030 ± 210 printed XY, ISO 527 (Bambu Lab); colorFabb 2960[4][5] |
| Elongation at break% | 4.2 ± 0.4 printed XY dry and 5.3 ± 0.3 conditioned, ISO 527 (Polymaker Fiberon); 3DXTech quotes 2.1 at break[1][2] | 8.6 ± 1.2 printed XY, ISO 527 (Bambu Lab); colorFabb 10.5 at break[4][5] |
| Flexural strengthMPa | 90 (printed XY, 3DXTech, ISO 178). Stratasys FDM Nylon 12CF spans 152-200 printed XZ against 61-73 in ZX (ASTM D790)[2][25] | 76 ± 4 printed XY, ISO 178 (Bambu Lab)[4] |
| Flexural modulusMPa | 7900 (printed XY, 3DXTech, ISO 178)[2] | 2640 ± 130 printed XY, ISO 178 (Bambu Lab); colorFabb 3295[4][5] |
| Charpy impact, notchedkJ/m² | 9.9 ± 0.7 printed XY dry and 10.2 ± 0.8 conditioned, ISO 179 notched (Polymaker Fiberon)[1] | 2.8 (colorFabb, ISO 179-1/1eA) and 8.8 ± 1.7 (Bambu Lab, ISO 179) printed XY, notched[4][5] |
| Other impact data | Izod notched 102-138 J/m printed XZ against 22.4-45.5 J/m in ZX (Stratasys FDM Nylon 12CF, ASTM D256)[25] | Charpy unnotched 27.3 (Bambu Lab) and 30.8 (colorFabb), printed, ISO 179[4][5] |
| Layer adhesion / Z tensileMPa | 52.2 ± 0.8 printed Z dry (Polymaker Fiberon) — 67 % of XY, unusually isotropic for a filled nylon; 42.1 ± 1.8 conditioned. Stratasys FDM Nylon 12CF gives 32.7-38.4 at break printed ZX (ASTM D638)[1][25] | 26 ± 3 printed Z, ISO 527 (Bambu Lab)[4] |
| Brittleness1–5 | Moderate[1] | Brittle — snaps with little warning[4] |
| Hardness (scale-specific)Shore A / Shore D / Rockwell | Rockwell M88 / R117 on extruded PA66-GF30 stock (ASTM D785); no figure is published for a carbon-fibre PA12 filament[26] | Not documented |
| Creep resistance / sustained load1–5 | Good. Ensinger rates its PA66-CF30 compound for sustained static and dynamic load at 110 °C continuous service; the PA12 matrix takes up 1.5 % equilibrium moisture against PA6's several per cent, so a PA12-CF part drifts less in service[27][1] | Poor — no glow-grade creep test; plain printed PLA sagged from 12 to 16.2–21.8 mm over 5 days at 1.25 kg[28][29][30] |
| Fatigue / repeated-flex resistance1–5 | Good. Stratasys sells unfilled FDM Nylon 12 specifically for repetitive-flex parts on the strength of its fatigue properties, and Ensinger reports improved fatigue strength for carbon-filled nylon compounds[27] | Poor — no grade-specific S-N curve; plain printed PLA ran 38 000–49 000 cycles at 30 % of tensile strength and the glow filler leaves a brittle, highly abrasive compound[31][4] |
| Elasticity / flexibility1–5 | Rigid[1] | Rigid[4] |
| Z strength as % of XY% | 31-50 (Stratasys FDM Nylon 12CF, ZX against XZ tensile at break, ASTM D638, five machine and tip combinations) against 67 (Polymaker Fiberon PA12-CF10, printed Z against XY)[1][25] | 81 by tensile, 72 by flexural (printed, Bambu Lab)[4] |
| Thermal Properties | ||
| HDT at 0.45 MPa°C | 131 (ISO 75, 0.45 MPa, Polymaker Fiberon). Stratasys FDM Nylon 12CF gives 160 printed XY and 168 ZX, and 175 with unidirectional toolpaths (ASTM D648 at 66 psi)[1][25] | 55 (ISO 75, 0.45 MPa)[4] |
| HDT at 1.8 MPa°C | 105 (ISO 75, 1.8 MPa, Polymaker Fiberon). Stratasys FDM Nylon 12CF gives 130 printed XY and 154 ZX (ASTM D648 at 264 psi)[1][25] | 52 (ISO 75, 1.8 MPa)[4] |
| Glass transition (Tg)°C | 55 (DSC, Polymaker Fiberon)[1] | 55 (DSC)[4] |
| Melting point / Vicat°C | 171 melting (DSC); Vicat 170.2 (ISO 306)[1] | 155 peak melt (DSC); colorFabb quotes above 155 by ISO 3146-C[4][5] |
| Thermal expansion (CTE)µm/m·K | Stratasys FDM Nylon 12CF gives 116 on XY-built and 37 on ZX-built specimens over -50 to 20 °C, rising to 181 (XY) and 46 (ZX) above the 37.5 °C glass transition (ASTM E831); Extrudr quotes 100 for DURAPRO PA12 CF (ISO 11359-2)[15][25] | Not documented |
| Flammability / UL 94 | Flammable; no UL 94 rating published for the grades surveyed[23] | Not documented |
| Environment & Chemical | ||
| UV resistance1–5 | Months outdoors before embrittlement — unstabilised polyamide yellows under UV[17] | Degrades within weeks outdoors[32] |
| Chemical resistance | Withstands oils, fuels and alkalis[17] | Not documented |
| Water / humidity resistance in service1–5 | Good — minor absorption; the most humidity-stable nylon composite here[14][1] | Not documented |
| Food contact | Not food-contact certified as filament[17] | Not documented |
| Biodegradability / compostability | Not biodegradable[17] | Not documented |
| Recyclability | Not accepted in household plastic collection[17] | Not documented |
| Electrical & ESD properties | Surface resistivity above 10¹² ohm — insulating (Polymaker Fiberon, ANSI/ESD S11.11)[1] | Not documented |
| Health & Safety | ||
| Fume toxicity1–5 | Moderate — measurable VOCs and UFPs, ventilation advised[33] | Low hazard — minimal VOC and particle emission[33] |
| VOC emission rateµg/min | Up to 180 caprolactam, the dominant VOC from nylon and the largest single-VOC rate in the study[33] | Not documented |
| Ultrafine-particle emission rateparticles/min | ≈2 × 10⁸ median for nylon — low for particles despite the highest VOC mass measured[33] | Not documented |
| Hazardous species emitted | Caprolactam, at up to 180 µg/min from nylon filament[33] | Not documented |
| Ventilation / filtration requirement1–5 | Ventilated room or enclosure recommended[33] | None needed in a normal room[33] |
| Dust & fibre handling hazard | Fibre is bound in the matrix; sanding dust should not be inhaled[23] | Not documented |
| Post-Processing | ||
| Sanding & machining | Sands poorly — gums rather than powders[18] | Not documented |
| Gluing & solvent welding | Cyanoacrylate; no common solvent welds polyamide[18] | Not documented |
| Vapour / chemical smoothing | No practical vapour smoothing[18] | Not documented |
| Support material pairing | Not documented | Support for PLA (Bambu Lab)[4] |
| Dimensional accuracy & detail | Polymaker's own conditioning test found PA12-CF10 was the only nylon that did not grow past its original size after moisture conditioning[14] | Glow brightness rises with wall thickness; 0.2 mm nozzles are not usable[16] |
| Solvents & Solubility | ||
| Soluble in | Formic acid, phenol, m-cresol and hexafluoroisopropanol dissolve the matrix at 23 °C, leaving the fibre; laboratory reagents.[34] | Chloroform dissolves the PLA matrix (10 % w/v, 2–4 h at 23 °C) and leaves the filler as loose sludge; laboratory reagent.[35] |
| Softened or crazed by | Zinc chloride solutions stress-crack the nylon matrix, alcoholic calcium chloride dissolves it, mineral acids attack it.[34] | Acetone, ethyl acetate and toluene plasticise the matrix but dissolve <1 % even at 65 °C; acetone submersion crazes parts.[35][36] |
| Solvent welding & smoothing agent | None — nylon's only solvents (formic acid, phenol, HFIP) degrade the part, and the fibre blocks surface flow anyway.[34] | Chloroform vapour attacks only the resin fraction, so the filler is left standing proud; no workshop-safe agent exists.[37][36] |
