Printing Parameters
Nozzle temperature°C190–230 on the Bambu Lab TDS against 210–240 in its own material table; colorFabb advises 195–220[4][15][5]190–230 (Bambu Lab)[3]

Enclosure / chamber requirement1–5Open frame is fine[4]Open frame is fine[3]
Part cooling fanFan on; colorFabb allows 0–100 %[4][5]Fan on[3]
Overall printing difficulty1–5Easy — minor profile tuning; a hardened nozzle is mandatory[15][7]Easy — minor profile tuning; 0.2 mm nozzles are not usable[15]
Extruder requirementBambu Lab: hardened steel and high-flow nozzles only, 0.2 mm excluded, AMS lite not compatible[15]Nozzles below 0.4 mm are not compatible (Bambu Lab)[15]
Hardware Wear & Reliability
Nozzle hardness required1–4Hardened steel required[15][7][5]Brass acceptable; hardened steel for volume work — Bambu Lab's compatibility table says no hardened nozzle is needed while the note under the same table groups PLA Marble with particle-filled materials that should always use one[15]
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[15][5]Moderately abrasive — stone fill[15][2]
Nozzle clog risk1–5Moderate — needs dry filament and a clean nozzle[15]Moderate — needs dry filament and a clean nozzle[15]
Hotend requirementHardened steel nozzle; Bambu Lab lists glow-in-the-dark among the filaments its hardened-steel nozzle exists for[16][15]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[15][5]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.[24]Chloroform dissolves the PLA matrix (10 % w/v, 2–4 h at 23 °C) and leaves the filler as loose sludge; laboratory reagent.[24]
Softened or crazed byAcetone, ethyl acetate and toluene plasticise the matrix but dissolve <1 % even at 65 °C; acetone submersion crazes parts.[24][25]Acetone, ethyl acetate and toluene plasticise the matrix but dissolve <1 % even at 65 °C; acetone submersion crazes parts.[24][25]
Solvent welding & smoothing agentChloroform vapour attacks only the resin fraction, so the filler is left standing proud; no workshop-safe agent exists.[26][25]Chloroform vapour attacks only the resin fraction, so the filler is left standing proud; no workshop-safe agent exists.[26][25]
