Identity & Market
Base polymer / chemistryPolyamide 11, polymerised from castor-oil-derived aminoundecanoic acid — a bio-based nylon[1][2]PLA with a phosphorescent additive at 2–20 wt% (Bambu Lab SDS, filler not named)[3]
Densityg/cm³1.02 (ISO 1183)[1]1.24 (colorFabb) to 1.26 (Bambu Lab), ISO 1183[4][5]
Typical priceUSD/kgNot documented1 kg spools cluster near 25[6][7]
Price range across brandsUSD/kgNot documented20–49 across brands; ELEGOO 20, Bambu Lab 25, Polymaker 25, Filament PM 49 on 0.5 kg spools[8][6][7][9]
Market availability1–5Niche, a handful of specialist brands[2]Stocked by most mainstream brands[6][7][8]
Spool sizes & diameters1.75 mm; 1 kg spools[2]1.75 and 2.85 mm; 0.75 and 1 kg spools[10][5]
Typical applicationsTough, chemically resistant functional parts; Prusa targets it at impact-loaded and vibration-loaded components[2]Signage, novelty and cosplay parts that glow after light exposure[4]
Diameter tolerance± mm±0.02 (Prusament)[1]Not documented
Printing Parameters
Nozzle temperature°C275 ± 10 (Prusament)[1]190–230 on the Bambu Lab TDS against 210–240 in its own material table; colorFabb advises 195–220[4][11][5]
Bed temperature°C100 ± 10 (Prusament)[1]35–45 (Bambu Lab); 50–60 (colorFabb)[4][5]
Enclosure / chamber requirement1–5Enclosure required (passive) — Prusament specifies a 55 ± 5 °C chamber[1]Open frame is fine[4]
Recommended chamber temperature°C55 ± 5 (Prusament)[1]Not documented
Part cooling fanNot documentedFan on; colorFabb allows 0–100 %[4][5]
Bed surface & adhesion aidPA nylon sheet (Prusament)[1]Not documented
Overall printing difficulty1–5Advanced — enclosure, hardware upgrades, tuning[1][12]Easy — minor profile tuning; a hardened nozzle is mandatory[11][7]
Extruder requirementPrusa printed its test specimens with a high-flow CHT nozzle[1]Bambu Lab: hardened steel and high-flow nozzles only, 0.2 mm excluded, AMS lite not compatible[11]
Hardware Wear & Reliability
Nozzle hardness required1–4Brass fine indefinitely for unfilled grades[12]Hardened steel required[11][7][5]
Abrasiveness1–5Non-abrasive when unfilled[12]Highly 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[11][5]
Nozzle clog risk1–5High — jams from moisture, heat creep or particles[13]Moderate — needs dry filament and a clean nozzle[11]
Hotend requirementNot documentedHardened steel nozzle; Bambu Lab lists glow-in-the-dark among the filaments its hardened-steel nozzle exists for[14][11]
Other hardware wearNot documentedBambu Lab reports the filament adds enough feeding resistance to fail prints on the AMS lite; colorFabb warns of brass nozzle wear[11][5]
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5High (0.8–2 %) — Prusa measures 0.46 % after 7 days at 22 % RH, but PA11 sits between PA12 and PA6 in the family[1][13]Moderate — 0.46 % saturated at 25 °C / 55 % RH[4]
Equilibrium moisture content at ~50 % RH%0.26 after 24 h and 0.46 after 7 days (Prusa Polymers method)[1]0.46 saturated at 25 °C / 55 % RH (Bambu Lab)[4]
Symptoms when wetPopping and cracking during extrusion, then hard-to-diagnose defects[15]Not documented
Effect of moisture on strengthPrusa publishes no dry-versus-conditioned columns; the CoPA reference shows the PA-family response — stiffness and strength fall sharply, impact and elongation rise[15][16]Polymaker 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[13]
Storage requirementSealed below 20 % RH with desiccant[13]Not documented
Mechanical Properties
Tensile strength (XY)MPa38.3 ± 0.8 printed horizontal and 39.5 ± 0.5 printed vertical at yield, ISO 527-1[1]32 ± 3 printed XY, ISO 527 (Bambu Lab); colorFabb quotes 61.5 by ISO 527 on its own specimens[4][5]
Young's modulusMPa1200 printed, both orientations, ISO 527-1[1]2030 ± 210 printed XY, ISO 527 (Bambu Lab); colorFabb 2960[4][5]
Elongation at break%5.6 ± 0.1 at yield, printed, ISO 527-1[1]8.6 ± 1.2 printed XY, ISO 527 (Bambu Lab); colorFabb 10.5 at break[4][5]
Flexural strengthMPaNot documented76 ± 4 printed XY, ISO 178 (Bambu Lab)[4]
Flexural modulusMPa1100 printed horizontal and 1000 printed vertical, ISO 178[1]2640 ± 130 printed XY, ISO 178 (Bambu Lab); colorFabb 3295[4][5]
Charpy impact, notchedkJ/m²12.9 ± 2.1 printed horizontal and 11.7 ± 1.2 printed vertical, ISO 179-1 notched[1]2.8 (colorFabb, ISO 179-1/1eA) and 8.8 ± 1.7 (Bambu Lab, ISO 179) printed XY, notched[4][5]
Other impact dataNot documentedCharpy unnotched 27.3 (Bambu Lab) and 30.8 (colorFabb), printed, ISO 179[4][5]
Layer adhesion / Z tensileMPa32 ± 1 (Prusa Polymers interlayer adhesion test) — the highest interlayer figure Prusa publishes for any of its filaments[1]26 ± 3 printed Z, ISO 527 (Bambu Lab)[4]
Brittleness1–5Tough — absorbs impact, yields before breaking[1]Brittle — snaps with little warning[4]
Hardness (scale-specific)Shore A / Shore D / Rockwell70 Shore D (Prusa Polymers method)[1]Not documented
Creep resistance / sustained load1–5Not documentedPoor — no glow-grade creep test; plain printed PLA sagged from 12 to 16.2–21.8 mm over 5 days at 1.25 kg[17][18][19]
Fatigue / repeated-flex resistance1–5Excellent — living hinges viable[12]Poor — 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[20][4]
Elasticity / flexibility1–5Semi-flexible[1]Rigid[4]
Z strength as % of XY%84 — Prusa publishes a tensile anisotropy coefficient of 0.84, the ratio of Z to XY tensile strength[1]81 by tensile, 72 by flexural (printed, Bambu Lab)[4]
Thermal Properties
HDT at 0.45 MPa°C58.7 (ISO 75, 0.45 MPa)[1]55 (ISO 75, 0.45 MPa)[4]
HDT at 1.8 MPa°C49.9 (ISO 75, 1.8 MPa)[1]52 (ISO 75, 1.8 MPa)[4]
Glass transition (Tg)°CNot documented55 (DSC)[4]
Melting point / Vicat°CNot documented155 peak melt (DSC); colorFabb quotes above 155 by ISO 3146-C[4][5]
Environment & Chemical
UV resistance1–5Not documentedDegrades within weeks outdoors[21]
Water / humidity resistance in service1–5Absorbs water, properties shift[15]Not documented
Biodegradability / compostabilityBio-based — the monomer comes from castor oil[2]Not documented
Health & Safety
Fume toxicity1–5Moderate — measurable VOCs and UFPs, ventilation advised[22]Low hazard — minimal VOC and particle emission[22]
VOC emission rateµg/minUp to 180 caprolactam, the dominant VOC from nylon; total VOC reached nearly 200 µg/min, the highest of the nine filaments tested[22]Not documented
Ultrafine-particle emission rateparticles/min≈2 × 10⁸ median — low for ultrafine particles despite the highest VOC mass of any filament tested[22]Not documented
Hazardous species emittedCaprolactam, at up to 180 µg/min from nylon filament — the largest single-VOC emission rate measured in the study[22]Not documented
Ventilation / filtration requirement1–5Ventilated room or enclosure recommended[22]None needed in a normal room[22]
Post-Processing
Support material pairingNot documentedSupport for PLA (Bambu Lab)[4]
Dimensional accuracy & detailNot documentedGlow brightness rises with wall thickness; 0.2 mm nozzles are not usable[11]
Solvents & Solubility
Soluble inDissolved at 23 °C by formic acid, phenol, m-cresol, 96 % sulphuric acid or hexafluoroisopropanol — all laboratory reagents.[23][24]Chloroform dissolves the PLA matrix (10 % w/v, 2–4 h at 23 °C) and leaves the filler as loose sludge; laboratory reagent.[25]
Softened or crazed byMineral acids, oxidants, halogens and zinc chloride solutions attack the amide bond; ordinary solvents do not (BASF, PA6/66).[23]Acetone, ethyl acetate and toluene plasticise the matrix but dissolve <1 % even at 65 °C; acetone submersion crazes parts.[25][26]
Solvent welding & smoothing agentNone — nylon's only solvents are formic acid, phenol and HFIP, all of which degrade the part they wet.[23]Chloroform vapour attacks only the resin fraction, so the filler is left standing proud; no workshop-safe agent exists.[27][26]
