Maximum volumetric flow (mm³/s; see test conditions)mm³/s14 at Bambu Lab's 180 mm/s cap on a 0.4 mm nozzle at 0.2 mm layer[2][16]Not documented
Warping tendency1–5Moderate — needs adhesion aid or draught shield; Bambu Lab positions the fibre as reducing warping[2]Moderate — needs adhesion aid or draught shield; the fibre cuts PEEK's crystallisation shrinkage[3]
Bed-adhesion difficulty1–5Needs a specific surface plus adhesive[12]Not documented
Stringing / oozing tendency1–5Slight — Polymaker advises 1–2 mm retraction at 20–30 mm/s[17]Not documented
Overall printing difficulty1–5Intermediate — dry filament and a tuned profile; hardened nozzle mandatory[12]Expert / industrial hardware only[13][14]
Hardware Wear & Reliability
Nozzle hardness required1–4Hardened steel required[12]Hardened steel required[3]
Abrasiveness1–5Highly abrasive — standard GF composite[12]Highly abrasive — standard CF composite[3]
Nozzle clog risk1–5Moderate — needs dry filament and a clean nozzle; 3DXTech specifies a hardened 0.4 mm minimum nozzle and 0.25 mm layers or higher for the glass-filled grade[18][19]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[20][19]
Heat-creep / jam sensitivity1–5Slightly sensitive[15]Not documented

Symptoms when wetBubbling and popping at the nozzle, stringing and a rough surface[21]Not documented
Effect of moisture on strengthPolymaker rates ABS moderate-sensitivity and publishes no dry-versus-conditioned figures; absorbed water flashes to steam in the hotend and shows as bubbling and poor layer adhesion[21]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[20]
Storage requirementSealed with desiccant; Polymaker rates ABS moderate-sensitivity[21]Not documented
Mechanical Properties
Tensile strength (XY)MPa36 ± 3 printed XY, ISO 527 (Bambu Lab); 3DXTech quotes 68 at break[2][1]105 at break (printed XY, ISO 527, CF10); 121 at yield on extruded CF30 stock (ASTM D638)[3][6]
Young's modulusMPa3160 ± 170 printed XY, ISO 527 (Bambu Lab); 3DXTech quotes 4210[2][1]8100 (printed XY, ISO 527, CF10) — more than double unfilled PEEK; 6343 on extruded CF30 stock (ASTM D638)[3][6]

Layer adhesion / Z tensileMPa29 ± 3 printed Z, ISO 527 (Bambu Lab)[2]Not documented
Brittleness1–5Brittle — snaps with little warning; notched Charpy falls from 21.5 to 4.2 kJ/m² against unfilled Bambu Lab ABS[2][23]Brittle — snaps with little warning; elongation falls from 28 % to 3 %[3][22]
Hardness (scale-specific)Shore A / Shore D / RockwellNot documentedRockwell M107 on extruded PEEK-CF30 stock (ASTM D785), against M100 unfilled[6][24]
Creep resistance / sustained load1–5Good — no creep test found; chopped glass fibre lifts modulus to 3160 MPa against 2200 for unfilled Bambu Lab ABS[2][23]Excellent — holds load for years. Ensinger rates carbon-fibre PEEK stock as very highly creep resistant and specifies 260 °C continuous service[6]
Fatigue / repeated-flex resistance1–5Below average — no S-N curve found; notched Charpy falls to 4.2 kJ/m² against 21.5 for unfilled Bambu Lab ABS[2][23]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[25][3][22]

Flammability / UL 94Not documentedUL 94 V-0 on the base resin; Ensinger lists extruded PEEK-CF30 stock as inherently flame resistant[22][6]
Environment & Chemical
Chemical resistanceGood against weak acids, weak alkalis, oils and grease; dissolved by acetone[26]Not documented
Food contactNot food safe — Polymaker cites potential chemical leaching[17]Not documented
Biodegradability / compostabilityNot biodegradable[17]Not documented
RecyclabilityMechanically recyclable but not accepted in household plastic collection[17]Not documented
Electrical & ESD propertiesNot documentedSurface resistance above 10⁹ ohm/sq — not static-dissipative (ASTM D257)[3]
Health & Safety
Fume toxicity1–5High — hazardous VOC such as styrene; enclosure and filtration needed[27][12]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[27]
VOC emission rateµg/min12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[27]Not documented
Ultrafine-particle emission rateparticles/min2 × 10¹⁰ to 9 × 10¹⁰ median across all ABS printers, two orders of magnitude above PLA's ≈1 × 10⁸[27]Not documented
Hazardous species emittedStyrene dominates. Bambu Lab states ABS and ASA release harmful gases such as styrene at printing temperature, which can be toxic and cause dizziness or nausea[27][12]Not documented
Ventilation / filtration requirement1–5Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[27][12]Ventilated room or enclosure recommended[27]
Dust & fibre handling hazardGlass fibre is bound in the matrix; avoid inhaling sanding dust[1]Carbon fibre is bound in the matrix; sanding dust should not be inhaled[3]
Post-Processing
Sanding & machiningSands well and takes filler before painting[17]Not documented
Painting & finishingPaints readily after light abrasion[17]Not documented
Support material pairingHIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[28][12]Not documented
Dimensional accuracy & detailBambu Lab describes a smooth matte finish with micro-spot gloss that blurs layer lines[2]Not documented
Solvents & Solubility
Soluble inAcetone dissolves the resin and leaves the fibre as sludge; MEK, THF, ethyl acetate and chlorinated solvents do the same.[29][26]95–98 wt% sulphuric acid dissolves the matrix at 40–70 °C and leaves the fibre. Nothing else touches PEEK.[30][29]
Softened or crazed byPetrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[29][31]Concentrated nitric, hydrofluoric, hydrobromic and hydriodic acids attack it; DCM, DMSO and THF swell thin-walled sections.[32][29]
Solvent welding & smoothing agentAcetone vapour reaches only the resin fraction, so the fibre is left standing proud of the smoothed surface.[33][26]None — no solvent softens PEEK, so parts are joined thermally or mechanically, never chemically.[32][29]
