| Identity & Market | ||
| Base polymer / chemistry | PLA with a phosphorescent additive at 2–20 wt% (Bambu Lab SDS, filler not named)[1] | Polyoxymethylene, normally the copolymer POM-C. Apium's filament grade is POM-C with antistatic additives; no unfilled POM filament was found on sale[2][3] |
| Densityg/cm³ | 1.24 (colorFabb) to 1.26 (Bambu Lab), ISO 1183[4][5] | 1.41 (extruded POM-C stock)[2] |
| Typical priceUSD/kg | 1 kg spools cluster near 25[6][7] | Not documented |
| Price range across brandsUSD/kg | 20–49 across brands; ELEGOO 20, Bambu Lab 25, Polymaker 25, Filament PM 49 on 0.5 kg spools[8][6][7][9] | Not documented |
| Market availability1–5 | Stocked by most mainstream brands[6][7][8] | Special order, 1-2 makers worldwide — Apium sells a POM-C ESD filament through its own shop and states its printers are the only ones able to process POM-C; no POM filament appears in the 3DJAKE or igo3d product sitemaps, at MatterHackers or at Printed Solid[3][10][11][12] |
| Spool sizes & diameters | 1.75 and 2.85 mm; 0.75 and 1 kg spools[13][5] | Not documented |
| Typical applications | Signage, novelty and cosplay parts that glow after light exposure[4] | Gears, bushings, bearings, conveyor and food-machinery parts; Apium markets its POM-C ESD grade for semiconductor insulators, aerospace fasteners and sliding parts[2][3] |
| Printing Parameters | ||
| Nozzle temperature°C | 190–230 on the Bambu Lab TDS against 210–240 in its own material table; colorFabb advises 195–220[4][14][5] | Not documented |
| Bed temperature°C | 35–45 (Bambu Lab); 50–60 (colorFabb)[4][5] | Not documented |
| Enclosure / chamber requirement1–5 | Open frame is fine[4] | Not documented |
| Part cooling fan | Fan on; colorFabb allows 0–100 %[4][5] | Not documented |
| Overall printing difficulty1–5 | Easy — minor profile tuning; a hardened nozzle is mandatory[14][7] | Not documented |
| Extruder requirement | Bambu Lab: hardened steel and high-flow nozzles only, 0.2 mm excluded, AMS lite not compatible[14] | Apium states that the adaptive heating system on its industrial machines is what makes POM-C printable, and that no other 3D printer can process it[3] |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Hardened steel required[14][7][5] | Not documented |
| Abrasiveness1–5 | 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[14][5] | Not documented |
| Nozzle clog risk1–5 | Moderate — needs dry filament and a clean nozzle[14] | Not documented |
| Hotend requirement | Hardened steel nozzle; Bambu Lab lists glow-in-the-dark among the filaments its hardened-steel nozzle exists for[15][14] | Not documented |
| Other hardware wear | Bambu 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)1–5 | Moderate — 0.46 % saturated at 25 °C / 55 % RH[4] | Low (0.1-0.3 %) — extruded POM-C stock takes up 0.18 % in 24 h and 0.80 % at saturation (ASTM D570)[2] |
| Equilibrium moisture content at ~50 % RH% | 0.46 saturated at 25 °C / 55 % RH (Bambu Lab)[4] | Not documented |
| Effect of moisture on strength | 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[16] | Not documented |
| Mechanical Properties | ||
| Tensile strength (XY)MPa | 32 ± 3 printed XY, ISO 527 (Bambu Lab); colorFabb quotes 61.5 by ISO 527 on its own specimens[4][5] | 66.9 at break and 64.1 at yield (extruded POM-C stock, ASTM D638; converted from 9700 and 9300 psi)[2] |
| Young's modulusMPa | 2030 ± 210 printed XY, ISO 527 (Bambu Lab); colorFabb 2960[4][5] | 2275 (extruded POM-C stock, ASTM D638; converted from 330,000 psi)[2] |

| Layer adhesion / Z tensileMPa | 26 ± 3 printed Z, ISO 527 (Bambu Lab)[4] | Not documented |
| Brittleness1–5 | Brittle — snaps with little warning[4] | Tough — absorbs impact, yields before breaking; extruded stock elongates 40 % before failing. No printed figure is published[2] |
| Hardness (scale-specific)Shore A / Shore D / Rockwell | Not documented | Rockwell 86 (and R120) — the source names only the R scale on extruded POM-C stock (ASTM D785)[2] |
| Creep resistance / sustained load1–5 | Poor — 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] | Not documented |
| Fatigue / repeated-flex resistance1–5 | 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] | Not documented |
| Elasticity / flexibility1–5 | Rigid[4] | Not documented |
| Z strength as % of XY% | 81 by tensile, 72 by flexural (printed, Bambu Lab)[4] | Not documented |
| Wear resistance & friction | Not documented | Wear factor 65e-10 in3*min/(ft*lb*h) and a dynamic coefficient of friction of 0.21 at 40 psi and 50 fpm (ASTM D3702, extruded stock) — the properties that make acetal the default gear and bushing plastic; Apium lists good sliding properties as the reason for its grade[2][3] |
| Thermal Properties | ||
| HDT at 0.45 MPa°C | 55 (ISO 75, 0.45 MPa)[4] | 158 (extruded POM-C stock, ASTM D648 at 66 psi; converted from 316 °F)[2] |

| Flammability / UL 94 | Not documented | UL 94 HB on extruded POM-C stock[2] |
| Environment & Chemical | ||
| UV resistance1–5 | Degrades within weeks outdoors[21] | Not documented |
| Chemical resistance | Not documented | Good chemical resistance, particularly to bases; Apium lists resistance to bases as a headline property[2][3] |
| Water / humidity resistance in service1–5 | Not documented | Good — minor absorption; 0.80 % water at saturation (ASTM D570, extruded stock)[2] |
| Electrical & ESD properties | Not documented | Volume resistance 1e14 ohm-cm, dielectric strength 500 V/mil and dielectric constant 3.7 at 60 Hz on extruded stock (ASTM D257, D149, D150); Apium's filament grade adds antistatic agents[2][3] |

| Ventilation / filtration requirement1–5 | None needed in a normal room[22] | Not documented |
| Post-Processing | ||
| Sanding & machining | Not documented | Easy to machine — Ensinger lists machinability as a headline property of POM-C stock[2] |
| Support material pairing | Support for PLA (Bambu Lab)[4] | Not documented |
| Dimensional accuracy & detail | Glow brightness rises with wall thickness; 0.2 mm nozzles are not usable[14] | Not documented |
| Solvents & Solubility | ||
| Soluble in | Chloroform dissolves the PLA matrix (10 % w/v, 2–4 h at 23 °C) and leaves the filler as loose sludge; laboratory reagent.[23] | Hexafluoroisopropanol dissolves it at room temperature; NMP and DMF only when hot. Laboratory reagents.[24] |
| Softened or crazed by | Acetone, ethyl acetate and toluene plasticise the matrix but dissolve <1 % even at 65 °C; acetone submersion crazes parts.[23][25] | Acids, oxidants, halogens and hot concentrated zinc chloride attack it; alcohols, ketones and esters do not.[24][26] |
| Solvent welding & smoothing agent | Chloroform vapour attacks only the resin fraction, so the filler is left standing proud; no workshop-safe agent exists.[27][25] | None — no solvent softens POM below its melting point, which is why it is bolted or heat-welded rather than glued.[24] |
