Market snapshot
Listing priceUSD/kg; dated snapshots$165.72/kg median; $165.72–$165.72/kg across 1 dated product listings$24.99/kg median; $19.99–$49.16/kg across 5 dated product listings
Identity & Market
Base polymer / chemistryButenediol vinyl alcohol copolymer — a vinyl alcohol copolymer that dissolves faster and in cooler water than straight PVA[1]PLA with a phosphorescent additive at 2–20 wt% (Bambu Lab SDS, filler not named)[2]
Densityg/cm³Not documented1.24 (colorFabb) to 1.26 (Bambu Lab), ISO 1183[3][4]
Typical priceUSD/kg1 kg-equivalent spools cluster near 166[1]1 kg spools cluster near 25[5][6]
Price range across brandsUSD/kg166 at Fiberlogy's 500 g pricing on 3DJake[1]20–49 across brands; ELEGOO 20, Bambu Lab 25, Polymaker 25, Filament PM 49 on 0.5 kg spools[7][5][6][8]
Market availability1–5Niche, a handful of specialist brands[1]Stocked by most mainstream brands[5][6][7]
Spool sizes & diameters1.75 and 2.85 mm; 0.5 kg spools[1]1.75 and 2.85 mm; 0.75 and 1 kg spools[9][4]
Typical applicationsDissolvable support where PVA dissolves too slowly, and for materials PVA bonds to poorly[1]Signage, novelty and cosplay parts that glow after light exposure[3]
Printing Parameters
Nozzle temperature°CNot documented190–230 on the Bambu Lab TDS against 210–240 in its own material table; colorFabb advises 195–220[3][10][4]
Bed temperature°CNot documented35–45 (Bambu Lab); 50–60 (colorFabb)[3][4]
Enclosure / chamber requirement1–5Open frame is fine[11]Open frame is fine[3]
Part cooling fanNot documentedFan on; colorFabb allows 0–100 %[3][4]
Overall printing difficulty1–5Intermediate — dry filament and a tuned profile[12]Easy — minor profile tuning; a hardened nozzle is mandatory[10][6]
Extruder requirementA second extruder or a tool changer[11]Bambu Lab: hardened steel and high-flow nozzles only, 0.2 mm excluded, AMS lite not compatible[10]
Hardware Wear & Reliability
Nozzle hardness required1–4Brass fine indefinitely[11]Hardened steel required[10][6][4]
Abrasiveness1–5Non-abrasive[11]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[10][4]
Nozzle clog risk1–5Very high — frequent jams without careful setup[12]Moderate — needs dry filament and a clean nozzle[10]
Hotend requirementNot documentedHardened steel nozzle; Bambu Lab lists glow-in-the-dark among the filaments its hardened-steel nozzle exists for[13][10]
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[10][4]
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5Very high (>2 %) — the vinyl alcohol backbone is what makes it soluble[12][11]Moderate — 0.46 % saturated at 25 °C / 55 % RH[3]
Equilibrium moisture content at ~50 % RH%Not documented0.46 saturated at 25 °C / 55 % RH (Bambu Lab)[3]
Effect of moisture on strengthNot a structural material; no dry-versus-conditioned data is published[12]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[12]
Storage requirementSealed with desiccant at all times[12]Not documented
Mechanical Properties
Tensile strength (XY)MPaNot documented32 ± 3 printed XY, ISO 527 (Bambu Lab); colorFabb quotes 61.5 by ISO 527 on its own specimens[3][4]
Young's modulusMPaNot documented2030 ± 210 printed XY, ISO 527 (Bambu Lab); colorFabb 2960[3][4]
Elongation at break%Not documented8.6 ± 1.2 printed XY, ISO 527 (Bambu Lab); colorFabb 10.5 at break[3][4]
Flexural strengthMPaNot documented76 ± 4 printed XY, ISO 178 (Bambu Lab)[3]
Flexural modulusMPaNot documented2640 ± 130 printed XY, ISO 178 (Bambu Lab); colorFabb 3295[3][4]
Charpy impact, notchedkJ/m²Not documented2.8 (colorFabb, ISO 179-1/1eA) and 8.8 ± 1.7 (Bambu Lab, ISO 179) printed XY, notched[3][4]
Other impact dataNot documentedCharpy unnotched 27.3 (Bambu Lab) and 30.8 (colorFabb), printed, ISO 179[3][4]
Layer adhesion / Z tensileMPaNot documented26 ± 3 printed Z, ISO 527 (Bambu Lab)[3]
Brittleness1–5Not documentedBrittle — snaps with little warning[3]
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[14][15][16]
Fatigue / repeated-flex resistance1–5Not documentedPoor — 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[17][3]
Elasticity / flexibility1–5Not documentedRigid[3]
Z strength as % of XY%Not documented81 by tensile, 72 by flexural (printed, Bambu Lab)[3]
Thermal Properties
HDT at 0.45 MPa°CNot documented55 (ISO 75, 0.45 MPa)[3]
HDT at 1.8 MPa°CNot documented52 (ISO 75, 1.8 MPa)[3]
Glass transition (Tg)°CNot documented55 (DSC)[3]
Melting point / Vicat°CNot documented155 peak melt (DSC); colorFabb quotes above 155 by ISO 3146-C[3][4]
Environment & Chemical
UV resistance1–5Not documentedDegrades within weeks outdoors[18]
Water / humidity resistance in service1–5Dissolves or disintegrates — by design[1]Not documented
Health & Safety
Fume toxicity1–5Low hazard — minimal VOC and particle emission; none of these materials was in the chamber study[19]Low hazard — minimal VOC and particle emission[19]
Ventilation / filtration requirement1–5Open a window / occasional ventilation[19]None needed in a normal room[19]
Post-Processing
Support material pairingThis is the support material[1]Support for PLA (Bambu Lab)[3]
Dimensional accuracy & detailNot documentedGlow brightness rises with wall thickness; 0.2 mm nozzles are not usable[10]
Solvents & Solubility
Soluble inWater: about 1 g of BVOH per 20 g of water, several hours; warmer water is faster but must not be too hot.[20][1]Chloroform dissolves the PLA matrix (10 % w/v, 2–4 h at 23 °C) and leaves the filler as loose sludge; laboratory reagent.[21]
Softened or crazed byNothing else — a vinyl alcohol copolymer resists organic solvents, so IPA or acetone will not touch it.[22]Acetone, ethyl acetate and toluene plasticise the matrix but dissolve <1 % even at 65 °C; acetone submersion crazes parts.[21][23]
Solvent welding & smoothing agentNone — water is a removal solvent, not a welding one.[20]Chloroform vapour attacks only the resin fraction, so the filler is left standing proud; no workshop-safe agent exists.[24][23]
