| Identity & Market | ||
| Base polymer / chemistry | Polyether ketone ketone, amorphous grade — a polyaryletherketone that stays amorphous, so it does not need PEEK's crystallisation control. Stratasys sells it as Antero 800NA and Antero 840CN03; category numbers below are unfilled unless a carbon grade is named[1][2] | PLA filled with wood powder — 10–18 wt% (Bambu Lab SDS); colorFabb woodFill uses a PLA/PHA base with recycled wood fibre[3][4] |
| Densityg/cm³ | 1.28 unfilled (ASTM D792, Antero 800NA; 1.31 annealed) and 1.33 for CarbonX PEKK-A CF15 (ISO 1183)[2][1] | 1.15 (colorFabb) to 1.23 (Fiberlogy), ISO 1183; Bambu Lab 1.21[5][4][6] |
| Typical priceUSD/kg | 1 kg-equivalent spools cluster near 550[7][8][9] | 1 kg spools cluster near 25; counting the 0.5 kg specialty spools the middle of the market is about 34[10][11][12] |
| Price range across brandsUSD/kg | 333-771 across grades and formats; 3DXTech CarbonX PEKK-A+CF15 333 at 2 kg, 3D4Makers unfilled PEKK-A 485 at 2 kg, IEMAI 3D 500 at 1 kg, Kimya PEKK Carbon 771 at 500 g[7][8][9][13][14] | 14–76 across brands; SUNLU 14, ELEGOO 19, Bambu Lab 25, Prusament 44, Filament PM 49 on 0.5 kg spools, colorFabb 76[11][10][15][16][17][12] |
| Market availability1–5 | Niche, a handful of specialist brands[7][8][9] | Stocked by most mainstream brands[10][11][16][6] |
| Spool sizes & diameters | 1.75 and 2.85 mm; 200 g to 2 kg spools, plus Stratasys canisters[7][8][2] | 1.75 and 2.85 mm; 0.6, 0.85 and 1 kg spools[16][6][10] |
| Typical applications | Aerospace interior and structural parts; 3DXTech labels its carbon-filled PEKK-A grade AERO and Stratasys certifies Antero 800NA for outgassing and FST[1][2] | Decorative and model-making prints that are sanded and stained like timber[5][4] |
| Diameter tolerance± mm | Not documented | ±0.03 (Bambu Lab)[5] |
| Printing Parameters | ||
| Nozzle temperature°C | Not documented | 190–240 (Bambu Lab); colorFabb advises 195–220 for its PLA/PHA base[5][4] |
| Bed temperature°C | 140 (3DXTech CarbonX PEKK-A CF15)[1] | 35–45 (Bambu Lab); 50–70 (Fiberlogy)[5][6] |
| Enclosure / chamber requirement1–5 | Actively heated chamber required[18][19] | Open frame is fine[5] |
| Part cooling fan | Not documented | Fan on[5] |
| Warping tendency1–5 | Not documented | None[5] |
| Overall printing difficulty1–5 | Expert / industrial hardware only[18][19] | Easy — minor profile tuning; pre-drying is required and the wood content chars if it sits hot[20][5] |
| Extruder requirement | Not documented | Nozzles below 0.4 mm are not compatible; Bambu Lab does not recommend the AMS lite[20] |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Hardened steel required — the category spans unfilled PEKK, where brass is acceptable, and the carbon-filled aerospace grades that make up most of the market[1][2] | 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[20][21] |
| Abrasiveness1–5 | Highly abrasive — most PEKK filament sold is carbon-filled; unfilled Antero 800NA and ThermaX PEKK-A are non-abrasive[1][2] | Moderately abrasive — wood fill[20] |
| Nozzle clog risk1–5 | Moderate — needs dry filament and a clean nozzle; 3DXTech lists no special nozzle concerns but a mandatory 120 °C pre-dry before every print[22] | Moderate — needs dry filament and a clean nozzle; wood particles char and block small nozzles[20] |
| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | Not documented | High — 1.25 % saturated at 25 °C / 55 % RH, the highest in the PLA family[5] |
| Equilibrium moisture content at ~50 % RH% | Not documented | 1.25 saturated at 25 °C / 55 % RH (Bambu Lab)[5] |
| Drying temperature & time | Not documented | 55 °C for 8 h in a forced-air dryer; Bambu Lab lists pre-drying as required[5][20] |
| Symptoms when wet | Not documented | Bambu Lab flags pre-drying and ventilation as specific requirements for this grade[20] |
| Effect of moisture on strength | No dry-versus-conditioned figures are published; 3DXTech mandates a 120 °C, 4 h pre-dry before every print because trapped water flashes to steam at these nozzle temperatures[22] | 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[23][5] |
| Mechanical Properties | ||
| Tensile strength (XY)MPa | 86.7-90.0 at yield and 73.0 at break (printed XZ, ASTM D638, Antero 800NA on the F900 and Fortus 450mc); 88.8 at break annealed; 126 at break for CarbonX PEKK-A CF15 (printed XY, ISO 527)[2][1] | 26 ± 5 (Bambu Lab) and 28.4 (colorFabb) printed XY, ISO 527; Fiberlogy quotes 35 at yield[5][4][6] |
| Young's modulusMPa | 2640-3870 (printed XZ, ASTM D638, Antero 800NA; upper figure annealed); 9125 for CarbonX PEKK-A CF15 (printed XY, ISO 527)[2][1] | 2360 ± 190 (Bambu Lab) and 2479 (colorFabb) printed XY, ISO 527; Fiberlogy 2950[5][4][6] |
| Elongation at break% | 6.1 at break (printed XZ, ASTM D638, Antero 800NA); 2.3 in ZX; 3.15 for CarbonX PEKK-A CF15 (ISO 527)[2][1] | 4.5 (colorFabb) to 15.3 (Bambu Lab) printed XY, ISO 527; Fiberlogy 6.5[5][4][6] |
| Flexural strengthMPa | 136 at 5 % strain (printed XZ, ASTM D790, Antero 800NA); 178 for CarbonX PEKK-A CF15 (printed XY, ISO 178)[2][1] | 55 ± 4 printed XY, ISO 178 (Bambu Lab)[5] |
| Flexural modulusMPa | 3200 (printed XZ, ASTM D790, Antero 800NA); 8817 for CarbonX PEKK-A CF15 (printed XY, ISO 178)[2][1] | 2780 ± 120 printed XY, ISO 178 (Bambu Lab)[5] |
| Charpy impact, notchedkJ/m² | Not documented | 3.81 (colorFabb) and 6.3 ± 2.2 (Bambu Lab) printed XY, ISO 179, notched[5][4] |
| Other impact data | Izod notched 41.1 J/m XZ and 33.3 J/m ZX; unnotched 1730 J/m XZ against 203 J/m ZX (printed, ASTM D256/D4812, Antero 800NA)[2] | Charpy unnotched 12.28 (colorFabb) and 15.7 (Bambu Lab), printed, ISO 179[5][4] |
| Layer adhesion / Z tensileMPa | 50.1-59.4 at yield (printed ZX, ASTM D638, Antero 800NA); 56.0 for the ESD grade Antero 840CN03[2][24] | 15 ± 4 printed Z, ISO 527 (Bambu Lab); flexural Z falls to 28 against 55 in XY[5] |
| Brittleness1–5 | Moderate unfilled — 6.1 % elongation at break in plane; brittle in the carbon-filled grades at 3.15 %[2][1] | Brittle — snaps with little warning[5] |
| Creep resistance / sustained load1–5 | Excellent — holds load for years. Antero 800NA still holds 82 % of its room-temperature ZX tensile strength at 104 °C and 63 % at 132 °C (printed, ASTM D638)[2] | 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[25][26][27] |
| Fatigue / repeated-flex resistance1–5 | Not documented | 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[28][5] |
| Elasticity / flexibility1–5 | Rigid[1] | Rigid[5] |
| Z strength as % of XY% | 56-82 (Antero 800NA and 840CN03 printed on the F900 and Fortus 450mc, ZX against XZ tensile yield and break, ASTM D638)[2][24] | 58 by tensile, 51 by flexural (printed, Bambu Lab)[5] |
| Thermal Properties | ||
| HDT at 0.45 MPa°C | 158 (printed XY and ZX, ASTM D648 Method B at 66 psi, Antero 800NA); 285 for CarbonX PEKK-A CF15 (ISO 75 at 0.45 MPa)[2][1] | 60 (ISO 75, 0.45 MPa)[5] |
| HDT at 1.8 MPa°C | 156-157 (printed, ASTM D648 Method B at 264 psi, Antero 800NA); moulded 147[2] | 57 (ISO 75, 1.8 MPa)[5] |
| Glass transition (Tg)°C | 156 (ASTM D7426, Antero 800NA); 165 for CarbonX PEKK-A CF15 (DSC)[2][1] | 54 (Bambu Lab, DSC); Fiberlogy quotes 55–60[5][6] |
| Melting point / Vicat°C | 300 melt point (ASTM D7426 peak heat, Antero 800NA); 305 for CarbonX PEKK-A CF15 (DSC)[2][1] | 156 peak melt (DSC)[5] |
| Thermal expansion (CTE)µm/m·K | 36.1 in XY and 50.2 in ZX (printed, 40-140 °C, ASTM E831, Antero 800NA); 47.4 and 51.2 for the ESD grade Antero 840CN03[2][24] | Not documented |
| Environment & Chemical | ||
| UV resistance1–5 | Good — years with some colour shift. 1000 h of QUV cycling to ASTM G154 left Antero 800NA's yield strength unchanged at 57 MPa and raised stress at break 3.6 %[2] | Degrades within weeks outdoors[29] |
| Electrical & ESD properties | Unfilled PEKK is an insulator at above 1.4e14 ohm-cm (ASTM D257); CarbonX PEKK-A CF15 sits above 10^7 ohm/sq, and the Antero 840CN03 ESD grade is specified at 10^4-10^9 ohm-cm[2][1][24] | Not documented |
| Health & Safety | ||
| Fume toxicity1–5 | Moderate — measurable VOCs and UFPs, ventilation advised. None of these polymers was in the chamber study, and all are processed far above the temperatures it covered[30] | Low hazard — minimal VOC and particle emission[30] |
| Ventilation / filtration requirement1–5 | Ventilated room or enclosure recommended[30] | None needed in a normal room; Bambu Lab specifically advises ventilation for this grade[20] |
| Dust & fibre handling hazard | Carbon fibre is bound in the matrix; sanding dust should not be inhaled[1] | Not documented |
| Post-Processing | ||
| Sanding & machining | Not documented | Sands and stains like timber — the usual reason for choosing it[4] |
| Support material pairing | Not documented | Support for PLA (Bambu Lab)[5] |
| Dimensional accuracy & detail | Not documented | Wood grain hides layer lines; colour darkens with nozzle temperature[5][4] |
| Solvents & Solubility | ||
| Soluble in | Concentrated sulphuric acid, as for PEEK; no common organic solvent touches a polyaryletherketone.[31][32] | Chloroform dissolves the PLA matrix (10 % w/v, 2–4 h at 23 °C) and leaves the filler as loose sludge; laboratory reagent.[33] |
| Softened or crazed by | Concentrated sulphuric acid and liquid Freon are the entries Ensinger marks not resistant; acetone, MEK and toluene do nothing.[31] | Acetone, ethyl acetate and toluene plasticise the matrix but dissolve <1 % even at 65 °C; acetone submersion crazes parts.[33][34] |
| Solvent welding & smoothing agent | None — no solvent softens a polyaryletherketone.[31] | Chloroform vapour attacks only the resin fraction, so the filler is left standing proud; no workshop-safe agent exists.[35][34] |
