| Identity & Market | ||
| Base polymer / chemistry | Short-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/cm³ | 1.39 (ISO 1183)[1] | 1.15 (colorFabb) to 1.23 (Fiberlogy), ISO 1183; Bambu Lab 1.21[7][6][8] |
| Typical priceUSD/kg | 1 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/kg | 448-972 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 availability1–5 | Niche, a handful of specialist brands[2][3] | Stocked by most mainstream brands[10][11][15][8] |
| Spool sizes & diameters | 1.75 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 applications | Stiff 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± mm | Not documented | ±0.03 (Bambu Lab)[7] |
| Printing Parameters | ||
| Nozzle temperature°C | Not documented | 190–240 (Bambu Lab); colorFabb advises 195–220 for its PLA/PHA base[7][6] |
| Bed temperature°C | Not documented | 35–45 (Bambu Lab); 50–70 (Fiberlogy)[7][8] |
| Enclosure / chamber requirement1–5 | Actively heated chamber required[17][18] | Open frame is fine[7] |
| Part cooling fan | Not documented | Fan on[7] |
| Warping tendency1–5 | Moderate — needs adhesion aid or draught shield; the fibre cuts PEEK's crystallisation shrinkage[1] | None[7] |
| Overall printing difficulty1–5 | Expert / 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 requirement | Not documented | Nozzles below 0.4 mm are not compatible; Bambu Lab does not recommend the AMS lite[19] |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Hardened 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] |
| Abrasiveness1–5 | Highly abrasive — standard CF composite[1] | Moderately abrasive — wood fill[19] |
| Nozzle clog risk1–5 | High — 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)1–5 | Not documented | High — 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 & time | Not documented | 55 °C for 8 h in a forced-air dryer; Bambu Lab lists pre-drying as required[7][19] |
| Symptoms when wet | Not documented | Bambu Lab flags pre-drying and ventilation as specific requirements for this grade[19] |
| 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[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)MPa | 105 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 modulusMPa | 8100 (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 strengthMPa | 136 (printed XY, ISO 178, CF10); 193 on extruded CF30 stock (ASTM D790)[1][4] | 55 ± 4 printed XY, ISO 178 (Bambu Lab)[7] |
| Flexural modulusMPa | 8300 (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/m² | Not documented | 3.81 (colorFabb) and 6.3 ± 2.2 (Bambu Lab) printed XY, ISO 179, notched[7][6] |
| Other impact data | Izod 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 tensileMPa | Not documented | 15 ± 4 printed Z, ISO 527 (Bambu Lab); flexural Z falls to 28 against 55 in XY[7] |
| Brittleness1–5 | Brittle — 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 / Rockwell | Rockwell M107 on extruded PEEK-CF30 stock (ASTM D785), against M100 unfilled[4][25] | Not documented |
| Creep resistance / sustained load1–5 | Excellent — 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 resistance1–5 | Good. 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 / flexibility1–5 | Rigid[1] | Rigid[7] |
| Z strength as % of XY% | Not documented | 58 by tensile, 51 by flexural (printed, Bambu Lab)[7] |
| Thermal Properties | ||
| HDT at 0.45 MPa°C | 265 (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°C | 316 on extruded CF30 stock, converted from 600 °F at 264 psi (ASTM D648)[4] | 57 (ISO 75, 1.8 MPa)[7] |
| Glass transition (Tg)°C | 143 (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°C | 334 melting on extruded CF30 stock, converted from 633 °F[4] | 156 peak melt (DSC)[7] |
| Continuous service temperature°C | 260 long-term on extruded CF30 stock, converted from 500 °F; 300 short term[4] | Not documented |
| Thermal expansion (CTE)µm/m·K | 14.4 (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 94 | UL 94 V-0 on the base resin; Ensinger lists extruded PEEK-CF30 stock as inherently flame resistant[24][4] | Not documented |
| Environment & Chemical | ||
| UV resistance1–5 | Not documented | Degrades within weeks outdoors[31] |
| Electrical & ESD properties | Surface resistance above 10⁹ ohm/sq — not static-dissipative (ASTM D257)[1] | 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[32] | Low hazard — minimal VOC and particle emission[32] |
| Ventilation / filtration requirement1–5 | Ventilated room or enclosure recommended[32] | None needed in a normal room; Bambu Lab specifically advises ventilation for this grade[19] |
| 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[6] |
| Support material pairing | Not documented | Support for PLA (Bambu Lab)[7] |
| Dimensional accuracy & detail | Not documented | Wood grain hides layer lines; colour darkens with nozzle temperature[7][6] |
| Solvents & Solubility | ||
| Soluble in | 95–98 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 by | Concentrated 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 agent | None — 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] |
