| Listing priceUSD/kg; dated snapshots | $170.36/kg median; $89.99–$796.00/kg across 4 dated product listings | $24.99/kg median; $19.99–$49.16/kg across 5 dated product listings |
| Identity & Market | ||
| Base polymer / chemistry | A carbon-filled compound conductive by volume rather than merely dissipative; Proto-pasta's is PLA-based, Recreus's and NinjaTek's are TPU, and add:north's Koltron G1 does not state its base polymer[1][2][3][4] | PLA with a phosphorescent additive at 2–20 wt% (Bambu Lab SDS, filler not named)[5] |
| Densityg/cm³ | Not documented | 1.24 (colorFabb) to 1.26 (Bambu Lab), ISO 1183[6][7] |
| Typical priceUSD/kg | 1 kg-equivalent spools span 90–181 for the carbon-filled grades; add:north's Koltron G1 sits far above at 796 because it is sold only in 100 and 250 g coils[8][9][10] | 1 kg spools cluster near 25[11][12] |
| Price range across brandsUSD/kg | 90–796 across brands; Proto-pasta conductive PLA 90 at 1 kg, Recreus Conductive Filaflex 160 at 500 g, NinjaTek Eel 181 at 1 kg, add:north Koltron G1 796 at 250 g[8][2][9][10] | 20–49 across brands; ELEGOO 20, Bambu Lab 25, Polymaker 25, Filament PM 49 on 0.5 kg spools[13][11][12][14] |
| Market availability1–5 | Niche, a handful of specialist brands[8][2] | Stocked by most mainstream brands[11][12][13] |
| Spool sizes & diameters | 1.75 and 2.85 mm; 0.05, 0.1, 0.25, 0.5, 1 and 2 kg spools[8][2][9][10] | 1.75 and 2.85 mm; 0.75 and 1 kg spools[15][7] |
| Typical applications | Capacitive touch surfaces, low-current traces, EMI shielding and static-safe fixtures[1] | Signage, novelty and cosplay parts that glow after light exposure[6] |
| Printing Parameters | ||
| Nozzle temperature°C | Not documented | 190–230 on the Bambu Lab TDS against 210–240 in its own material table; colorFabb advises 195–220[6][16][7] |
| Bed temperature°C | Not documented | 35–45 (Bambu Lab); 50–60 (colorFabb)[6][7] |
| Enclosure / chamber requirement1–5 | Open frame is fine[1] | Open frame is fine[6] |
| Part cooling fan | Not documented | Fan on; colorFabb allows 0–100 %[6][7] |
| Overall printing difficulty1–5 | Intermediate — dry filament and a tuned profile[1] | Easy — minor profile tuning; a hardened nozzle is mandatory[16][12] |
| Extruder requirement | Not documented | Bambu Lab: hardened steel and high-flow nozzles only, 0.2 mm excluded, AMS lite not compatible[16] |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Brass acceptable; hardened steel for volume work[1] | Hardened steel required[16][12][7] |
| Abrasiveness1–5 | Moderately abrasive — conductive carbon filler[1] | 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[16][7] |
| Nozzle clog risk1–5 | Low — Proto-pasta states the carbon-filled grade prints on standard PLA settings with no special nozzle required[1] | Moderate — needs dry filament and a clean nozzle[16] |
| Hotend requirement | Not documented | Hardened steel nozzle; Bambu Lab lists glow-in-the-dark among the filaments its hardened-steel nozzle exists for[17][16] |
| Other hardware wear | Not documented | Bambu Lab reports the filament adds enough feeding resistance to fail prints on the AMS lite; colorFabb warns of brass nozzle wear[16][7] |
| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | Not documented | Moderate — 0.46 % saturated at 25 °C / 55 % RH[6] |
| Equilibrium moisture content at ~50 % RH% | Not documented | 0.46 saturated at 25 °C / 55 % RH (Bambu Lab)[6] |
| Effect of moisture on strength | Polymaker rates PLA low-sensitivity and publishes no dry-versus-conditioned figures; absorbed water flashes to steam and shows as bubbling and poor layer adhesion[18] | 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[18] |
| Mechanical Properties | ||
| Tensile strength (XY)MPa | Not documented | 32 ± 3 printed XY, ISO 527 (Bambu Lab); colorFabb quotes 61.5 by ISO 527 on its own specimens[6][7] |
| Young's modulusMPa | Not documented | 2030 ± 210 printed XY, ISO 527 (Bambu Lab); colorFabb 2960[6][7] |
| Elongation at break% | Not documented | 8.6 ± 1.2 printed XY, ISO 527 (Bambu Lab); colorFabb 10.5 at break[6][7] |
| Flexural strengthMPa | Not documented | 76 ± 4 printed XY, ISO 178 (Bambu Lab)[6] |
| Flexural modulusMPa | Not documented | 2640 ± 130 printed XY, ISO 178 (Bambu Lab); colorFabb 3295[6][7] |
| Charpy impact, notchedkJ/m² | Not documented | 2.8 (colorFabb, ISO 179-1/1eA) and 8.8 ± 1.7 (Bambu Lab, ISO 179) printed XY, notched[6][7] |
| Other impact data | Not documented | Charpy unnotched 27.3 (Bambu Lab) and 30.8 (colorFabb), printed, ISO 179[6][7] |
| Layer adhesion / Z tensileMPa | Not documented | 26 ± 3 printed Z, ISO 527 (Bambu Lab)[6] |
| Brittleness1–5 | Brittle — snaps with little warning; carbon-black loading at conductive levels embrittles PLA[1] | Brittle — snaps with little warning[6] |
| Creep resistance / sustained load1–5 | Not documented | 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[19][20][21] |
| Fatigue / repeated-flex resistance1–5 | Not documented | 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[22][6] |
| Elasticity / flexibility1–5 | Rigid[1] | Rigid[6] |
| Z strength as % of XY% | Not documented | 81 by tensile, 72 by flexural (printed, Bambu Lab)[6] |
| Thermal Properties | ||
| HDT at 0.45 MPa°C | Not documented | 55 (ISO 75, 0.45 MPa)[6] |
| HDT at 1.8 MPa°C | Not documented | 52 (ISO 75, 1.8 MPa)[6] |
| Glass transition (Tg)°C | Not documented | 55 (DSC)[6] |
| Melting point / Vicat°C | Not documented | 155 peak melt (DSC); colorFabb quotes above 155 by ISO 3146-C[6][7] |
| Environment & Chemical | ||
| UV resistance1–5 | Not documented | Degrades within weeks outdoors[23] |
| Electrical & ESD properties | Conductive rather than dissipative — Proto-pasta sells the grade as electrically conductive composite PLA[1] | Not documented |
| Health & Safety | ||
| Fume toxicity1–5 | Low hazard — minimal VOC and particle emission; none of these materials was in the chamber study[24] | Low hazard — minimal VOC and particle emission[24] |
| Ventilation / filtration requirement1–5 | Open a window / occasional ventilation[24] | None needed in a normal room[24] |
| Dust & fibre handling hazard | Conductive carbon filler is bound in the matrix; avoid inhaling sanding dust[1] | Not documented |
| Post-Processing | ||
| Support material pairing | Not documented | Support for PLA (Bambu Lab)[6] |
| Dimensional accuracy & detail | Not documented | Glow brightness rises with wall thickness; 0.2 mm nozzles are not usable[16] |
| Solvents & Solubility | ||
| Soluble in | Chloroform dissolves PLA-based grades, leaving the carbon black; TPU-based grades need DMF, NMP or THF. Laboratory reagents.[25][26] | 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 by | Acetone and ethyl acetate plasticise a PLA-based grade; a TPU-based grade swells in toluene, esters and alcohols.[25][26] | Acetone, ethyl acetate and toluene plasticise the matrix but dissolve <1 % even at 65 °C; acetone submersion crazes parts.[25][27] |
| Solvent welding & smoothing agent | None — neither PLA nor TPU has a workshop-safe welding or smoothing solvent.[25][26] | Chloroform vapour attacks only the resin fraction, so the filler is left standing proud; no workshop-safe agent exists.[28][27] |
