Identity & Market
Base polymer / chemistryShort-fibre reinforced PEEK. 3DXTech's CarbonX grade is nominally 10 wt% carbon and its FibreX grade 20 wt% glass; LEHVOSS Luvocom 3F PEEK CF 9676 is 15 wt% carbon; Ensinger's machining stock runs to 30 wt% carbon[1][2][3][4]PLA filled with wood powder — 10–18 wt% (Bambu Lab SDS); colorFabb woodFill uses a PLA/PHA base with recycled wood fibre[5][6]
Densityg/cm³1.39 (ISO 1183)[1]1.15 (colorFabb) to 1.23 (Fiberlogy), ISO 1183; Bambu Lab 1.21[7][6][8]
Typical priceUSD/kg1 kg-equivalent spools span 448–972; the middle of the market is about 598[2][3][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/kg448-972 across formats and filler types; IEMAI 3D CF-PEEK and GF-PEEK 448 at 1 kg, 3DXTech CarbonX PEEK+CF10 598 at 2 kg and FibreX PEEK+GF20 695 at 1 kg, Luvocom 3F PEEK CF 9676 648 at 2 kg[2][3][9][13]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][14][15][16][12]
Market availability1–5Niche, a handful of specialist brands[2][3]Stocked by most mainstream brands[10][11][15][8]
Spool sizes & diameters1.75 and 2.85 mm; 200 g to 2 kg spools[2][3]1.75 and 2.85 mm; 0.6, 0.85 and 1 kg spools[15][8][10]
Typical applicationsStiff aerospace and oil-and-gas parts where PEEK alone is not rigid enough[1]Decorative and model-making prints that are sanded and stained like timber[7][6]
Diameter tolerance± mmNot documented±0.03 (Bambu Lab)[7]
Printing Parameters
Nozzle temperature°CNot documented190–240 (Bambu Lab); colorFabb advises 195–220 for its PLA/PHA base[7][6]
Bed temperature°CNot documented35–45 (Bambu Lab); 50–70 (Fiberlogy)[7][8]
Enclosure / chamber requirement1–5Actively heated chamber required[17][18]Open frame is fine[7]
Part cooling fanNot documentedFan on[7]
Warping tendency1–5Moderate — needs adhesion aid or draught shield; the fibre cuts PEEK's crystallisation shrinkage[1]None[7]
Overall printing difficulty1–5Expert / industrial hardware only[17][18]Easy — minor profile tuning; pre-drying is required and the wood content chars if it sits hot[19][7]
Extruder requirementNot documentedNozzles below 0.4 mm are not compatible; Bambu Lab does not recommend the AMS lite[19]
Hardware Wear & Reliability
Nozzle hardness required1–4Hardened steel required[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[19][20]
Abrasiveness1–5Highly abrasive — standard CF composite[1]Moderately abrasive — wood fill[19]
Nozzle clog risk1–5High — jams from moisture, heat creep or particles; 3DXTech adds a hardened 0.4 mm minimum nozzle and 0.25 mm layers to the mandatory 120 °C pre-dry[21][22]Moderate — needs dry filament and a clean nozzle; wood particles char and block small nozzles[19]
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5Not documentedHigh — 1.25 % saturated at 25 °C / 55 % RH, the highest in the PLA family[7]
Equilibrium moisture content at ~50 % RH%0.06 in 24 h on extruded CF30 stock (ASTM D570)[4]1.25 saturated at 25 °C / 55 % RH (Bambu Lab)[7]
Drying temperature & timeNot documented55 °C for 8 h in a forced-air dryer; Bambu Lab lists pre-drying as required[7][19]
Symptoms when wetNot documentedBambu Lab flags pre-drying and ventilation as specific requirements for this grade[19]
Effect of moisture on strengthNo 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[21]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][7]
Mechanical Properties
Tensile strength (XY)MPa105 at break (printed XY, ISO 527, CF10); 121 at yield on extruded CF30 stock (ASTM D638)[1][4]26 ± 5 (Bambu Lab) and 28.4 (colorFabb) printed XY, ISO 527; Fiberlogy quotes 35 at yield[7][6][8]
Young's modulusMPa8100 (printed XY, ISO 527, CF10) — more than double unfilled PEEK; 6343 on extruded CF30 stock (ASTM D638)[1][4]2360 ± 190 (Bambu Lab) and 2479 (colorFabb) printed XY, ISO 527; Fiberlogy 2950[7][6][8]
Elongation at break%3 at break (printed XY, ISO 527), against 28 for unfilled PEEK[1][24]4.5 (colorFabb) to 15.3 (Bambu Lab) printed XY, ISO 527; Fiberlogy 6.5[7][6][8]
Flexural strengthMPa136 (printed XY, ISO 178, CF10); 193 on extruded CF30 stock (ASTM D790)[1][4]55 ± 4 printed XY, ISO 178 (Bambu Lab)[7]
Flexural modulusMPa8300 (printed XY, ISO 178, CF10); 7171 on extruded CF30 stock (ASTM D790)[1][4]2780 ± 120 printed XY, ISO 178 (Bambu Lab)[7]
Charpy impact, notchedkJ/m²Not documented3.81 (colorFabb) and 6.3 ± 2.2 (Bambu Lab) printed XY, ISO 179, notched[7][6]
Other impact dataIzod notched 61.9 J/m on extruded CF30 stock, converted from 1.16 ft-lb/in (ASTM D256)[4]Charpy unnotched 12.28 (colorFabb) and 15.7 (Bambu Lab), printed, ISO 179[7][6]
Layer adhesion / Z tensileMPaNot documented15 ± 4 printed Z, ISO 527 (Bambu Lab); flexural Z falls to 28 against 55 in XY[7]
Brittleness1–5Brittle — snaps with little warning; elongation falls from 28 % to 3 %[1][24]Brittle — snaps with little warning[7]
Hardness (scale-specific)Shore A / Shore D / RockwellRockwell M107 on extruded PEEK-CF30 stock (ASTM D785), against M100 unfilled[4][25]Not documented
Creep resistance / sustained load1–5Excellent — holds load for years. Ensinger rates carbon-fibre PEEK stock as very highly creep resistant and specifies 260 °C continuous service[4]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[26][27][28]
Fatigue / repeated-flex resistance1–5Good. Victrex rates PEEK for long-term fatigue as well as creep; the fibre cuts elongation at break from 28 % to 3 %, which limits repeated large-strain flexing[29][1][24]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[30][7]
Elasticity / flexibility1–5Rigid[1]Rigid[7]
Z strength as % of XY%Not documented58 by tensile, 51 by flexural (printed, Bambu Lab)[7]
Thermal Properties
HDT at 0.45 MPa°C265 (printed XY, ISO 75 at 0.45 MPa, CarbonX PEEK+CF10) against 140 for unfilled PEEK[1][24]60 (ISO 75, 0.45 MPa)[7]
HDT at 1.8 MPa°C316 on extruded CF30 stock, converted from 600 °F at 264 psi (ASTM D648)[4]57 (ISO 75, 1.8 MPa)[7]
Glass transition (Tg)°C143 (DSC, CarbonX PEEK+CF10) — the fibre does not move the glass transition[1]54 (Bambu Lab, DSC); Fiberlogy quotes 55–60[7][8]
Melting point / Vicat°C334 melting on extruded CF30 stock, converted from 633 °F[4]156 peak melt (DSC)[7]
Continuous service temperature°C260 long-term on extruded CF30 stock, converted from 500 °F; 300 short term[4]Not documented
Thermal expansion (CTE)µm/m·K14.4 (extruded PEEK-CF30 stock, ASTM D696; source states 0.80e-5 in/in/°F) — about a third of unfilled PEEK[4][25]Not documented
Flammability / UL 94UL 94 V-0 on the base resin; Ensinger lists extruded PEEK-CF30 stock as inherently flame resistant[24][4]Not documented
Environment & Chemical
UV resistance1–5Not documentedDegrades within weeks outdoors[31]
Electrical & ESD propertiesSurface resistance above 10⁹ ohm/sq — not static-dissipative (ASTM D257)[1]Not documented
Health & Safety
Fume toxicity1–5Moderate — 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[32]Low hazard — minimal VOC and particle emission[32]
Ventilation / filtration requirement1–5Ventilated room or enclosure recommended[32]None needed in a normal room; Bambu Lab specifically advises ventilation for this grade[19]
Dust & fibre handling hazardCarbon fibre is bound in the matrix; sanding dust should not be inhaled[1]Not documented
Post-Processing
Sanding & machiningNot documentedSands and stains like timber — the usual reason for choosing it[6]
Support material pairingNot documentedSupport for PLA (Bambu Lab)[7]
Dimensional accuracy & detailNot documentedWood grain hides layer lines; colour darkens with nozzle temperature[7][6]
Solvents & Solubility
Soluble in95–98 wt% sulphuric acid dissolves the matrix at 40–70 °C and leaves the fibre. Nothing else touches PEEK.[33][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 byConcentrated nitric, hydrofluoric, hydrobromic and hydriodic acids attack it; DCM, DMSO and THF swell thin-walled sections.[36][34]Acetone, ethyl acetate and toluene plasticise the matrix but dissolve <1 % even at 65 °C; acetone submersion crazes parts.[35][37]
Solvent welding & smoothing agentNone — no solvent softens PEEK, so parts are joined thermally or mechanically, never chemically.[36][34]Chloroform vapour attacks only the resin fraction, so the filler is left standing proud; no workshop-safe agent exists.[38][37]
