| Identity & Market | ||
| Base polymer / chemistry | Carbon-filled polyamide compounded to a static-dissipative resistivity — Polymaker's grade uses a PA612 matrix[1] | PLA filled with wood powder — 10–18 wt% (Bambu Lab SDS); colorFabb woodFill uses a PLA/PHA base with recycled wood fibre[2][3] |
| Densityg/cm³ | 1.10 (ISO 1183)[1] | 1.15 (colorFabb) to 1.23 (Fiberlogy), ISO 1183; Bambu Lab 1.21[4][3][5] |
| Typical priceUSD/kg | 1 kg-equivalent spools cluster near 130[6] | 1 kg spools cluster near 25; counting the 0.5 kg specialty spools the middle of the market is about 34[7][8][9] |
| Price range across brandsUSD/kg | 130 at Polymaker's 0.5 kg pricing[6] | 14–76 across brands; SUNLU 14, ELEGOO 19, Bambu Lab 25, Prusament 44, Filament PM 49 on 0.5 kg spools, colorFabb 76[8][7][10][11][12][9] |
| Market availability1–5 | Special order, 1–2 makers worldwide[6] | Stocked by most mainstream brands[7][8][11][5] |
| Spool sizes & diameters | 1.75 mm; 0.5 kg spools[6] | 1.75 and 2.85 mm; 0.6, 0.85 and 1 kg spools[11][5][7] |
| Typical applications | Electronics jigs and trays that also need nylon toughness and heat resistance[1] | Decorative and model-making prints that are sanded and stained like timber[4][3] |
| Diameter tolerance± mm | Not documented | ±0.03 (Bambu Lab)[4] |
| Printing Parameters | ||
| Nozzle temperature°C | Not documented | 190–240 (Bambu Lab); colorFabb advises 195–220 for its PLA/PHA base[4][3] |
| Bed temperature°C | Not documented | 35–45 (Bambu Lab); 50–70 (Fiberlogy)[4][5] |
| Enclosure / chamber requirement1–5 | Enclosure required (passive)[13] | Open frame is fine[4] |
| Part cooling fan | Not documented | Fan on[4] |
| Bed surface & adhesion aid | PEI sheet with a glue stick, or a dedicated adhesive such as Magigoo[14][13] | Not documented |
| Warping tendency1–5 | Not documented | None[4] |
| Bed-adhesion difficulty1–5 | Needs a specific surface plus adhesive[14] | Not documented |
| Stringing / oozing tendency1–5 | Moderate — retraction tuning needed[13] | Not documented |
| Overall printing difficulty1–5 | Expert / industrial hardware only[13][15] | Easy — minor profile tuning; pre-drying is required and the wood content chars if it sits hot[16][4] |
| Extruder requirement | Not documented | Nozzles below 0.4 mm are not compatible; Bambu Lab does not recommend the AMS lite[16] |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Hardened steel required — Polymaker measures brass nozzle life at about 9 h on PA612-ESD and recommends hardened steel or ruby[1] | Brass acceptable; hardened steel for volume work — Bambu Lab's PLA compatibility table lists no hardened-nozzle requirement, but its nozzle guide names wood among the abrasive filaments hardened steel exists for[16][17] |
| Abrasiveness1–5 | Highly abrasive — carbon-filled nylon composite; Polymaker puts brass nozzle life at roughly 9 h on PA612-ESD[1] | Moderately abrasive — wood fill[16] |
| Nozzle clog risk1–5 | High — jams from moisture, heat creep or particles[15] | Moderate — needs dry filament and a clean nozzle; wood particles char and block small nozzles[16] |
| Heat-creep / jam sensitivity1–5 | Moderate — good heatbreak cooling needed[14] | Not documented |
| Hotend requirement | May require an all-metal hot end (Simplify3D)[14] | Not documented |
| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | High (0.8–2 %) — the PA612 matrix sits between PA6 and PA12[18][19] | High — 1.25 % saturated at 25 °C / 55 % RH, the highest in the PLA family[4] |
| Equilibrium moisture content at ~50 % RH% | Not documented | 1.25 saturated at 25 °C / 55 % RH (Bambu Lab)[4] |
| Drying temperature & time | Not documented | 55 °C for 8 h in a forced-air dryer; Bambu Lab lists pre-drying as required[4][16] |
| Symptoms when wet | Not documented | Bambu Lab flags pre-drying and ventilation as specific requirements for this grade[16] |
| Effect of moisture on strength | Polymaker publishes dry and wet printed blocks for PA612-ESD itself: at 4.64 % moisture tensile falls 84.3 → 73.6 MPa and modulus 4294 → 3731 MPa[1][19] | No dry-versus-conditioned figures are published. At 1.25 % saturated uptake the practical loss shows as poor layer adhesion, rough surface and weak layers[15][4] |
| 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[20][21] | Not documented |
| Mechanical Properties | ||
| Tensile strength (XY)MPa | 84.3 ± 2.3 printed XY dry (annealed 100 °C/16 h), 73.6 ± 2.3 conditioned to 4.64 % moisture, ISO 527[1] | 26 ± 5 (Bambu Lab) and 28.4 (colorFabb) printed XY, ISO 527; Fiberlogy quotes 35 at yield[4][3][5] |
| Young's modulusMPa | 4293.7 ± 116.4 printed XY dry and 3730.8 ± 156.2 conditioned, ISO 527[1] | 2360 ± 190 (Bambu Lab) and 2479 (colorFabb) printed XY, ISO 527; Fiberlogy 2950[4][3][5] |
| Elongation at break% | 3.0 ± 0.1 printed XY dry and 4.2 ± 0.4 conditioned, ISO 527[1] | 4.5 (colorFabb) to 15.3 (Bambu Lab) printed XY, ISO 527; Fiberlogy 6.5[4][3][5] |
| Flexural strengthMPa | Not documented | 55 ± 4 printed XY, ISO 178 (Bambu Lab)[4] |
| Flexural modulusMPa | Not documented | 2780 ± 120 printed XY, ISO 178 (Bambu Lab)[4] |
| Charpy impact, notchedkJ/m² | 5.9 ± 0.4 printed XY dry and 4.9 ± 0.3 conditioned, ISO 179 notched[1] | 3.81 (colorFabb) and 6.3 ± 2.2 (Bambu Lab) printed XY, ISO 179, notched[4][3] |
| Other impact data | Charpy unnotched 24.1 ± 2.4 printed XY and 4.5 ± 0.2 printed Z (ISO 179)[1] | Charpy unnotched 12.28 (colorFabb) and 15.7 (Bambu Lab), printed, ISO 179[4][3] |
| Layer adhesion / Z tensileMPa | 21.5 ± 2.7 printed Z dry — only a quarter of XY, the most anisotropic nylon composite here; 19.2 ± 1.6 conditioned[1] | 15 ± 4 printed Z, ISO 527 (Bambu Lab); flexural Z falls to 28 against 55 in XY[4] |
| Brittleness1–5 | Brittle — snaps with little warning; elongation 3.0 % in XY and 1.4 % in Z[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 conductive carbon-filled nylon filament[22] | 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 PA612 matrix here still takes up 4.64 % moisture at conditioning, which softens it[23][1] | Poor — no wood-filled creep test; plain printed PLA sagged from 12 to 16.2–21.8 mm over 5 days at 1.25 kg[24][25][26] |
| Fatigue / repeated-flex resistance1–5 | Good. Ensinger states carbon-filled PA66 compounds have improved fatigue strength in tension, flexure and compression[23] | Poor — no grade-specific S-N curve; plain printed PLA ran 38 000–49 000 cycles at 30 % of tensile strength and the wood filler cuts elongation and the parts snap without warning[27][4] |
| Elasticity / flexibility1–5 | Rigid[1] | Rigid[4] |
| Z strength as % of XY% | 26 (printed Z against XY tensile)[1] | 58 by tensile, 51 by flexural (printed, Bambu Lab)[4] |
| Thermal Properties | ||
| HDT at 0.45 MPa°C | 157.0 (ISO 75, 0.45 MPa)[1] | 60 (ISO 75, 0.45 MPa)[4] |
| HDT at 1.8 MPa°C | 125.4 (ISO 75, 1.8 MPa)[1] | 57 (ISO 75, 1.8 MPa)[4] |
| Glass transition (Tg)°C | 41.8 (DSC)[1] | 54 (Bambu Lab, DSC); Fiberlogy quotes 55–60[4][5] |
| Melting point / Vicat°C | 187.3 melting (DSC); Vicat 190.0 (ISO 306)[1] | 156 peak melt (DSC)[4] |
| Flammability / UL 94 | Flammable; no UL 94 rating published for the grades surveyed[20] | Not documented |
| Environment & Chemical | ||
| UV resistance1–5 | Months outdoors before embrittlement — unstabilised polyamide yellows under UV[13] | Degrades within weeks outdoors[28] |
| Chemical resistance | Withstands oils, fuels and alkalis[13] | Not documented |
| Food contact | Not food-contact certified as filament[13] | Not documented |
| Biodegradability / compostability | Not biodegradable[13] | Not documented |
| Recyclability | Not accepted in household plastic collection[13] | Not documented |
| Electrical & ESD properties | Static-dissipative — the reason the grade exists; Polymaker's insulating nylon composites sit above 10¹² ohm by contrast[1][18] | Not documented |
| Health & Safety | ||
| Fume toxicity1–5 | Moderate — measurable VOCs and UFPs, ventilation advised[29] | Low hazard — minimal VOC and particle emission[29] |
| VOC emission rateµg/min | Up to 180 caprolactam, the dominant VOC from nylon and the largest single-VOC rate in the study[29] | Not documented |
| Ultrafine-particle emission rateparticles/min | ≈2 × 10⁸ median for nylon — low for particles despite the highest VOC mass measured[29] | Not documented |
| Hazardous species emitted | Caprolactam, at up to 180 µg/min from nylon filament[29] | Not documented |
| Ventilation / filtration requirement1–5 | Ventilated room or enclosure recommended[29] | None needed in a normal room; Bambu Lab specifically advises ventilation for this grade[16] |
| Dust & fibre handling hazard | Fibre is bound in the matrix; sanding dust should not be inhaled[20] | Not documented |
| Post-Processing | ||
| Sanding & machining | Sands poorly — gums rather than powders[14] | Sands and stains like timber — the usual reason for choosing it[3] |
| Gluing & solvent welding | Cyanoacrylate; no common solvent welds polyamide[14] | Not documented |
| Vapour / chemical smoothing | No practical vapour smoothing[14] | Not documented |
| Support material pairing | Not documented | Support for PLA (Bambu Lab)[4] |
| Dimensional accuracy & detail | Not documented | Wood grain hides layer lines; colour darkens with nozzle temperature[4][3] |
| Solvents & Solubility | ||
| Soluble in | Formic acid, phenol, m-cresol and hexafluoroisopropanol dissolve the matrix at 23 °C, leaving the fibre; laboratory reagents.[30] | Chloroform dissolves the PLA matrix (10 % w/v, 2–4 h at 23 °C) and leaves the filler as loose sludge; laboratory reagent.[31] |
| Softened or crazed by | Zinc chloride solutions stress-crack the nylon matrix, alcoholic calcium chloride dissolves it, mineral acids attack it.[30] | Acetone, ethyl acetate and toluene plasticise the matrix but dissolve <1 % even at 65 °C; acetone submersion crazes parts.[31][32] |
| Solvent welding & smoothing agent | None — nylon's only solvents (formic acid, phenol, HFIP) degrade the part, and the fibre blocks surface flow anyway.[30] | Chloroform vapour attacks only the resin fraction, so the filler is left standing proud; no workshop-safe agent exists.[33][32] |
