Typical applicationsSignage, novelty and cosplay parts that glow after light exposure[4]Stiff, chemically resistant parts where PP-CF's cost or conductivity is unwanted[3]
Diameter tolerance± mmNot documented±0.04 (Prusament)[2]
Printing Parameters
Nozzle temperature°C190–230 on the Bambu Lab TDS against 210–240 in its own material table; colorFabb advises 195–220[4][14][5]245 ± 10 (Prusament) — 25 °C below the carbon-fibre grade[2][15]
Bed temperature°C35–45 (Bambu Lab); 50–60 (colorFabb)[4][5]95 ± 10 (Prusament)[2]
Enclosure / chamber requirement1–5Open frame is fine[4]Enclosure recommended — Simplify3D lists an enclosure as a hardware requirement and Polymaker advises one below 70 °C ambient to stop warping and cracking[16][17]
Part cooling fanFan on; colorFabb allows 0–100 %[4][5]Off — Prusa runs 0 % except 100 % on bridges[2]
Maximum volumetric flow (mm³/s; see test conditions)mm³/sNot documented4 at Prusa's 50 mm/s cap on a 0.4 mm nozzle at 0.2 mm layer[2][18]
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 difficulty1–5Easy — minor profile tuning; a hardened nozzle is mandatory[14][7]Advanced — enclosure, hardware upgrades, tuning; hardened nozzle mandatory[2]
Extruder requirementBambu Lab: hardened steel and high-flow nozzles only, 0.2 mm excluded, AMS lite not compatible[14]Prusa states a hardened nozzle is necessary and recommends a brim[2]
Hardware Wear & Reliability
Nozzle hardness required1–4Hardened steel required[14][7][5]Hardened steel required[2]
Abrasiveness1–5Highly abrasive — the phosphor is a hard ceramic; Bambu Lab groups glow with carbon fibre as the materials that wear nozzles and grind AMS PTFE, and both Bambu Lab and Polymaker require a hardened nozzle[14][5]Highly abrasive — standard GF composite[2]
Nozzle clog risk1–5Moderate — needs dry filament and a clean nozzle[14]Moderate — needs dry filament and a clean nozzle; Prusa lists higher risk of nozzle clogging for glass-filled composites[19]
Hotend requirementHardened steel nozzle; Bambu Lab lists glow-in-the-dark among the filaments its hardened-steel nozzle exists for[20][14]Not documented
Other hardware wearBambu Lab reports the filament adds enough feeding resistance to fail prints on the AMS lite; colorFabb warns of brass nozzle wear[14][5]Not documented
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5Moderate — 0.46 % saturated at 25 °C / 55 % RH[4]Low (0.1–0.3 %) — 0.11 % at both 24 h and 7 days, higher than the carbon-fibre grade's 0.04 % but still very low[2][15]
Equilibrium moisture content at ~50 % RH%0.46 saturated at 25 °C / 55 % RH (Bambu Lab)[4]0.11 after 24 h and 0.11 after 7 days at 24 °C / 22 % RH (Prusa Polymers)[2]
Effect of moisture on strengthPolymaker rates PLA low-sensitivity and publishes no dry-versus-conditioned figures for this grade; absorbed water flashes to steam and shows as bubbling and poor layer adhesion[21]Not applicable in practice at 0.11 % equilibrium uptake[2]
Storage requirementNot documentedNo special storage needed[2]
Mechanical Properties
Tensile strength (XY)MPa32 ± 3 printed XY, ISO 527 (Bambu Lab); colorFabb quotes 61.5 by ISO 527 on its own specimens[4][5]46.6 ± 1.3 filament tensile yield (Prusament, ISO 527) — more than double the carbon-fibre grade's 21[2][15]
Young's modulusMPa2030 ± 210 printed XY, ISO 527 (Bambu Lab); colorFabb 2960[4][5]Not documented
Elongation at break%8.6 ± 1.2 printed XY, ISO 527 (Bambu Lab); colorFabb 10.5 at break[4][5]Not documented
Flexural strengthMPa76 ± 4 printed XY, ISO 178 (Bambu Lab)[4]Not documented
Flexural modulusMPa2640 ± 130 printed XY, ISO 178 (Bambu Lab); colorFabb 3295[4][5]Not documented
Charpy impact, notchedkJ/m²2.8 (colorFabb, ISO 179-1/1eA) and 8.8 ± 1.7 (Bambu Lab, ISO 179) printed XY, notched[4][5]7.9 ± 0.4 printed horizontal and 9.9 ± 0.8 printed vertical XZ (ISO 179-1, notched)[2]
Other impact dataCharpy unnotched 27.3 (Bambu Lab) and 30.8 (colorFabb), printed, ISO 179[4][5]Not documented
Layer adhesion / Z tensileMPa26 ± 3 printed Z, ISO 527 (Bambu Lab)[4]Not documented
Brittleness1–5Brittle — snaps with little warning[4]Moderate[2]
Hardness (scale-specific)Shore A / Shore D / RockwellNot documentedRockwell R102 (and M95) on extruded unfilled PP stock (ASTM D785); no figure is published for a glass-fibre PP filament[22]
Creep resistance / sustained load1–5Poor — no glow-grade creep test; plain printed PLA sagged from 12 to 16.2–21.8 mm over 5 days at 1.25 kg[23][24][25]Not documented
Fatigue / repeated-flex resistance1–5Poor — no grade-specific S-N curve; plain printed PLA ran 38 000–49 000 cycles at 30 % of tensile strength and the glow filler leaves a brittle, highly abrasive compound[26][4]Not documented
Elasticity / flexibility1–5Rigid[4]Rigid[2]
Z strength as % of XY%81 by tensile, 72 by flexural (printed, Bambu Lab)[4]Not documented
Thermal Properties

HDT at 1.8 MPa°C52 (ISO 75, 1.8 MPa)[4]112.6 (ISO 75, 1.8 MPa)[2]
Glass transition (Tg)°C55 (DSC)[4]Not documented
Melting point / Vicat°C155 peak melt (DSC); colorFabb quotes above 155 by ISO 3146-C[4][5]Not documented
Environment & Chemical
UV resistance1–5Degrades within weeks outdoors[27]Not documented
Chemical resistanceNot documentedExcellent against acids, alkalis and most solvents[17]
Water / humidity resistance in service1–5Not documentedExcellent — essentially unaffected[2]
Health & Safety
Fume toxicity1–5Low hazard — minimal VOC and particle emission[28]Low 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[28]
Ventilation / filtration requirement1–5None needed in a normal room[28]Open a window / occasional ventilation. Inferred — no polyolefin was measured in the chamber study[28]
Dust & fibre handling hazardNot documentedGlass fibre is bound in the matrix; avoid inhaling sanding dust[2]
Post-Processing
Support material pairingSupport for PLA (Bambu Lab)[4]Not documented
Dimensional accuracy & detailGlow brightness rises with wall thickness; 0.2 mm nozzles are not usable[14]Not documented
Solvents & Solubility
Soluble inChloroform dissolves the PLA matrix (10 % w/v, 2–4 h at 23 °C) and leaves the filler as loose sludge; laboratory reagent.[29]None at room temperature; chloroform dissolves the matrix at 60 °C and xylene at about 118 °C, leaving the fibre.[30][31]
Softened or crazed byAcetone, ethyl acetate and toluene plasticise the matrix but dissolve <1 % even at 65 °C; acetone submersion crazes parts.[29][32]Xylene, decalin, CCl4 and chlorobenzene are heavily absorbed at 20 °C; oleum, chlorosulphonic acid and bromine destroy it.[30]
Solvent welding & smoothing agentChloroform vapour attacks only the resin fraction, so the filler is left standing proud; no workshop-safe agent exists.[33][32]None — nothing softens PP at room temperature, so joints have to be welded thermally rather than chemically.[30]
