| Typical applications | Stiff parts that must stay dimensionally stable in changing humidity — Polymaker sells this grade specifically on low moisture sensitivity[10][1] | Chemical-plant fittings, semiconductor handling and parts needing outstanding UV and chemical resistance[3] |
| Printing Parameters | ||
| Nozzle temperature°C | 260–290 (Extrudr DURAPRO PA12 CF)[11] | Not documented |
| Bed temperature°C | 110 (Extrudr DURAPRO PA12 CF)[11] | 70–110 (3DXTech FluorX)[3] |
| Enclosure / chamber requirement1–5 | Enclosure required (passive)[12][1] | Enclosure required (passive)[3] |
| Bed surface & adhesion aid | PEI sheet with a glue stick, or a dedicated adhesive such as Magigoo[13][12] | 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[11][14] | Not documented |
| Warping tendency1–5 | Not documented | High — enclosure needed for reliable large parts[3] |
| Bed-adhesion difficulty1–5 | Needs a specific surface plus adhesive[13] | Not documented |
| Stringing / oozing tendency1–5 | Moderate — retraction tuning needed[12] | Not documented |
| Overall printing difficulty1–5 | Advanced — enclosure, hardware upgrades, tuning[12] | Expert / industrial hardware only[3][4] |
| 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] | Brass fine indefinitely for unfilled grades[3] |
| Abrasiveness1–5 | Highly abrasive — standard CF composite; Polymaker puts brass nozzle life at roughly 9 h on PA12-CF10[1] | Non-abrasive when unfilled[3] |
| Nozzle clog risk1–5 | High — jams from moisture, heat creep or particles[15] | Low — 3DXTech lists no special nozzle concerns, no minimum layer height and states drying is not required[9] |
| Heat-creep / jam sensitivity1–5 | Moderate — good heatbreak cooling needed[13] | Not documented |
| Hotend requirement | May require an all-metal hot end (Simplify3D)[13] | Not documented |
| Other hardware wear | Not documented | Hydrogen fluoride released on overheating is extremely corrosive and will attack hotend and enclosure metalwork as well as people[4] |
| 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][16] | Negligible (<0.1 % EMC) — fluoropolymers are essentially non-hygroscopic[3] |
| Equilibrium moisture content at ~50 % RH% | 1.5 equilibrium water absorption (Polymaker Fiberon PA12-CF10)[1] | Not documented |
| Drying temperature & time | 80–100 °C; storage below 20 % RH[15][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][10] | Not applicable in practice — 3DXTech states drying is not required for PVDF, so there is no moisture-driven strength loss to measure[9] |
| Storage requirement | Sealed below 20 % RH with desiccant[15] | 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[17][18] | 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][19] | 51 at break (printed XY, ISO 527)[3] |
| 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][19] | 2450 (printed XY, ISO 527)[3] |
| 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] | 25 at break (printed XY, ISO 527)[3] |
| 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][19] | 50 (printed XY, ISO 178)[3] |
| Flexural modulusMPa | 7900 (printed XY, 3DXTech, ISO 178)[2] | 1800 (printed XY, ISO 178)[3] |
| Charpy impact, notchedkJ/m² | 9.9 ± 0.7 printed XY dry and 10.2 ± 0.8 conditioned, ISO 179 notched (Polymaker Fiberon)[1] | Not documented |
| 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)[19] | Izod 133 J/m on extruded PVDF stock, converted from 2.49 ft-lb/in (ASTM D256)[20] |
| 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][19] | Not documented |
| Brittleness1–5 | Moderate[1] | Tough — absorbs impact, yields before breaking[3] |
| 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[21] | Rockwell M79 on extruded PVDF stock (ASTM D785)[20] |
| 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[22][1] | Not documented |
| 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[22] | Not documented |
| Elasticity / flexibility1–5 | Rigid[1] | Slightly flexible in thin sections[3] |
| 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][19] | Not documented |
| 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][19] | 149 on extruded PVDF stock (ASTM D648 at 66 psi; converted from 300 °F)[20] |
| 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][19] | 113 on extruded PVDF stock (ASTM D648 at 264 psi; converted from 235 °F)[20] |
| Glass transition (Tg)°C | 55 (DSC, Polymaker Fiberon)[1] | Not documented |
| Melting point / Vicat°C | 171 melting (DSC); Vicat 170.2 (ISO 306)[1] | 170 melting (ISO 11357)[3] |
| Continuous service temperature°C | Not documented | 149 long term and short term on extruded PVDF stock (converted from 300 °F)[20] |
| 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)[11][19] | 127.8 (extruded PVDF stock, ASTM D696; source states 7.1e-5 in/in/°F) — the highest thermal expansion of any engineering polymer in this dataset[20] |
| Flammability / UL 94 | Flammable; no UL 94 rating published for the grades surveyed[17] | UL 94 V-0 on extruded PVDF stock; Ensinger lists inherent flame resistance[20] |
| Environment & Chemical | ||
| UV resistance1–5 | Months outdoors before embrittlement — unstabilised polyamide yellows under UV[12] | Excellent — designed for permanent outdoor use; Ensinger lists good UV and weather resistance and high gamma radiation resistance for PVDF stock[3][20] |
| Chemical resistance | Withstands oils, fuels and alkalis[12] | Outstanding — resistant to most acids, solvents and oxidising agents, which is the reason to use it[3] |
| Water / humidity resistance in service1–5 | Good — minor absorption; the most humidity-stable nylon composite here[10][1] | Excellent — essentially unaffected[3] |
| Food contact | Not food-contact certified as filament[12] | Not documented |
| Biodegradability / compostability | Not biodegradable[12] | Not documented |
| Recyclability | Not accepted in household plastic collection[12] | 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[23] | Very high — toxic decomposition products; local exhaust mandatory. Above 315 °C thermal decomposition yields hydrofluoric acid, hydrogen cyanide and carbon monoxide[4] |
| VOC emission rateµg/min | Up to 180 caprolactam, the dominant VOC from nylon and the largest single-VOC rate in the study[23] | Not documented |
| Ultrafine-particle emission rateparticles/min | ≈2 × 10⁸ median for nylon — low for particles despite the highest VOC mass measured[23] | Not documented |
| Hazardous species emitted | Caprolactam, at up to 180 µg/min from nylon filament[23] | Above 315 °C: hydrofluoric acid, hydrogen cyanide, phenols, carbon monoxide, carbon dioxide and dense smoke. HF is extremely corrosive, its skin burns may not be immediately visible or painful, and exposure can be fatal by skin absorption, inhalation or ingestion[4] |
| Ventilation / filtration requirement1–5 | Ventilated room or enclosure recommended[23] | Local exhaust to outside / fume hood — the SDS states local exhaust is preferred[4] |
| Dust & fibre handling hazard | Fibre is bound in the matrix; sanding dust should not be inhaled[17] | Molten polymer causes thermal burns and must not be pulled off the skin. If HF is detected during a decomposition event, cut the heat but keep the extraction running, ventilate, and clear non-essential people from the area[4] |
| Post-Processing | ||
| Sanding & machining | Sands poorly — gums rather than powders[13] | Not documented |
| Gluing & solvent welding | Cyanoacrylate; no common solvent welds polyamide[13] | Not documented |
| Vapour / chemical smoothing | No practical vapour smoothing[13] | Not documented |
| 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[10] | The processing window sits well below the 315 °C decomposition threshold, so nozzle temperature must be controlled rather than raised to chase flow[3][4] |
| Solvents & Solubility | ||
| Soluble in | Formic acid, phenol, m-cresol and hexafluoroisopropanol dissolve the matrix at 23 °C, leaving the fibre; laboratory reagents.[24] | THF, MEK, DMF, DMAc, NMP, DMSO and trimethyl phosphate dissolve 5–10 wt% at ambient — Arkema's active solvents, all lab reagents.[25] |
| Softened or crazed by | Zinc chloride solutions stress-crack the nylon matrix, alcoholic calcium chloride dissolves it, mineral acids attack it.[24] | Acetone, MIBK, cyclohexanone, butyl acetate and glycol ethers swell it; alkalis above pH 12 attack the homopolymer.[25][26] |
| Solvent welding & smoothing agent | None — nylon's only solvents (formic acid, phenol, HFIP) degrade the part, and the fibre blocks surface flow anyway.[24] | None for the workshop — the active solvents (NMP, DMAc, DMF) are laboratory reagents used for casting membranes, not joints.[25] |
