Identity & Market
Base polymer / chemistryPolyether block amide: rigid polyamide and flexible polyether blocks.[1]Polypropylene reinforced with chopped carbon fibre[2][3]
Densityg/cm³1.01 g/cm³ (GB/T 1033; eSUN manufacturer data)[1]0.91 (Prusament PP Carbon Fiber, ISO 1183)[2]
Typical priceUSD/kgNot documented1 kg-equivalent spools span 57–138; the middle of the market is about 108[4][5][6]
Price range across brandsUSD/kgNot documented57–138 across brands; Reli3D 57 at 700 g on Amazon, Prusament 108 direct from Prusa and 138 at Printed Solid, 3DXTech CarbonX PP+CF 120[4][7][5][6]
Market availability1–5Not documentedAvailable from several mainstream brands[5][7]
Spool sizes & diameters1.75 mm diameter, 1 kg spool.[8]1.75 mm; 0.65 kg spools[7][5]
Typical applicationsManufacturer applications include footwear, sports equipment and cushioning.[1]Lightweight chemical-resistant parts, automotive clips and ducting that must survive above 150 °C[9]
Diameter tolerance± mmNot documented±0.04 (Prusament)[2]
Printing Parameters
Nozzle temperature°C230–260 °C; 240 °C recommended.[1]270 ± 10 (Prusament)[2]
Bed temperature°C60–90 °C[1]85 ± 10 (Prusament)[2]
Enclosure / chamber requirement1–5Not documentedEnclosure recommended — Simplify3D lists an enclosure as a hardware requirement and Polymaker advises one below 70 °C ambient to stop warping and cracking[10][11]
Part cooling fan10–50% fan recommended; mechanical-test specimens used 50–100%.[1]Off — Prusa runs 0 % except 100 % on bridges[2]
Bed surface & adhesion aidPEI build plate[1]Not documented
Maximum volumetric flow (mm³/s; see test conditions)mm³/s9 mm³/s maximum in eSUN spiral-vase test; mechanical specimens used 2 mm³/s. Linear recommendation 25–110 mm/s is a separate quantity.[1]3.2 at Prusa's 40 mm/s cap on a 0.4 mm nozzle at 0.2 mm layer[2][12]
Warping tendency1–5Not documentedHigh — enclosure needed for reliable large parts; Prusa recommends a brim[2]
Bed-adhesion difficulty1–5Not documentedVery difficult — special plates or slurry required[2]
Overall printing difficulty1–5Not documentedAdvanced — enclosure, hardware upgrades, tuning; hardened nozzle mandatory[2]
Extruder requirementNot documentedPrusa states a hardened nozzle is necessary and recommends a brim[2]
Hardware Wear & Reliability
Nozzle hardness required1–4Not documentedHardened steel required — Prusa states plainly that a hardened nozzle is necessary[2]
Abrasiveness1–5Not documentedHighly abrasive — standard CF composite[2]
Nozzle clog risk1–5Not documentedModerate — needs dry filament and a clean nozzle; 3DXTech specifies a hardened 0.4 mm minimum nozzle and 0.25 mm layers or higher, and Prusa lists composites as a higher clogging risk[3][13]
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5Not documentedNegligible (<0.1 % EMC) — Prusa measures 0.03 % in 24 h and 0.04 % in 7 days on its PP composite, the lowest figures it publishes for any filament[2]
Equilibrium moisture content at ~50 % RH%Not documented0.03 after 24 h and 0.04 after 7 days at 24 °C / 22 % RH (Prusa Polymers)[2]
Drying temperature & time70–75 °C for 6–8 h; re-dry after receiving or extended exposure.[1]Not documented
Effect of moisture on strengthNot documentedNot applicable in practice at 0.04 % equilibrium uptake[2]
Storage requirementNot documentedNo special storage needed[2]
Mechanical Properties
Tensile strength (XY)MPa>16.5 MPa printed XY, GB/T 1040; manufacturer lower bound, not an exact measurement.[1]21 ± 0.4 filament tensile yield (Prusament, ISO 527)[2]
Elongation at break%>520% printed XY, GB/T 1040; manufacturer lower bound.[1]Not documented
Charpy impact, notchedkJ/m²Not documented14.5 ± 0.3 printed horizontal and 10.5 ± 0.8 printed vertical XZ (ISO 179-1, notched)[2]
Layer adhesion / Z tensileMPa7.5 MPa printed Z, GB/T 1040 (manufacturer test)[1]Not documented
Brittleness1–5Not documentedTough — absorbs impact, yields before breaking[2]
Hardness (scale-specific)Shore A / Shore D / Rockwell90 Shore A nominal grade designation; do not compare numerically with Shore D or Rockwell.[8]Rockwell R102 (and M95) on extruded unfilled PP stock (ASTM D785); no figure is published for a carbon-fibre PP filament[14]
Fatigue / repeated-flex resistance1–5Not documentedGood[15]
Elasticity / flexibility1–5Not documentedSlightly flexible in thin sections[2]
Thermal Properties
HDT at 0.45 MPa°CNot documented158 (ISO 75, 0.45 MPa) — far above unfilled PP and above most engineering filaments[2]
HDT at 1.8 MPa°CNot documented115 (ISO 75, 1.8 MPa)[2]
Melting point / Vicat°C110 °C Vicat softening (GB/T 1633, 120 °C/h, 10 N); not HDT or a continuous-use rating.[1]Not documented
Environment & Chemical
Chemical resistanceNot documentedExcellent against acids, alkalis and most solvents[11]
Water / humidity resistance in service1–5Not documentedExcellent — essentially unaffected[2]
Health & Safety
Fume toxicity1–5Not documentedLow hazard — minimal VOC and particle emission. Inferred: no polyolefin was among the nine filaments in the Azimi chamber study, so this is a family-level judgement rather than a measurement[16]
Ventilation / filtration requirement1–5Not documentedOpen a window / occasional ventilation. Inferred — no polyolefin was measured in the chamber study[16]
Dust & fibre handling hazardNot documentedCarbon fibre is bound in the matrix; sanding dust should not be inhaled[2]
Solvents & Solubility
Soluble inNot documentedNone at room temperature; chloroform dissolves the matrix at 60 °C and xylene at about 118 °C, leaving the fibre.[17][18]
Softened or crazed byNot documentedXylene, decalin, CCl4 and chlorobenzene are heavily absorbed at 20 °C; oleum, chlorosulphonic acid and bromine destroy it.[17]
Solvent welding & smoothing agentNot documentedNone — nothing softens PP at room temperature, so joints have to be welded thermally rather than chemically.[17]

Material entries describe families or representative grades, not an interchangeable specification for every spool. Test methods, orientations and conditions may differ. Unknown values are marked “Not documented”. Prices and source dates remain historical snapshots; check the linked guide for product details. Differences highlight text, not a universal winner.
