| 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[3][16][4] |
| Bed temperature°C | Not documented | 35–45 (Bambu Lab); 50–60 (colorFabb)[3][4] |
| Enclosure / chamber requirement1–5 | Enclosure recommended[17] | Open frame is fine[3] |
| Part cooling fan | Not documented | Fan on; colorFabb allows 0–100 %[3][4] |
| Bed surface & adhesion aid | Clean the plate and apply glue; Simplify3D also lists Kapton tape and ABS slurry[17][18] | Not documented |
| Warping tendency1–5 | Moderate — needs adhesion aid or draught shield; the fibre reduces warping against unfilled ABS[17] | Not documented |
| Bed-adhesion difficulty1–5 | Needs a specific surface plus adhesive[17] | Not documented |
| Stringing / oozing tendency1–5 | Slight — Polymaker advises 1–2 mm retraction at 20–30 mm/s[19] | Not documented |
| Overall printing difficulty1–5 | Intermediate — dry filament and a tuned profile; hardened nozzle mandatory[17] | Easy — minor profile tuning; a hardened nozzle is mandatory[16][11] |
| 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 | Hardened steel required[17] | Hardened steel required[16][11][4] |
| Abrasiveness1–5 | Highly abrasive — standard CF composite[17] | 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][4] |
| Nozzle clog risk1–5 | Moderate — needs dry filament and a clean nozzle; 3DXTech specifies a hardened nozzle of 0.4 mm minimum and 0.25 mm layers or higher, and Prusa lists composites as a higher clogging risk[20][21][22] | Moderate — needs dry filament and a clean nozzle[16] |
| Heat-creep / jam sensitivity1–5 | Slightly sensitive[18] | Not documented |
| Hotend requirement | No special hot-end required[18] | Hardened steel nozzle; Bambu Lab lists glow-in-the-dark among the filaments its hardened-steel nozzle exists for[23][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][4] |
| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | Moderate — the ABS matrix takes up 0.51–0.65 % saturated at 25 °C / 55 % RH and 3DXTech specifies a 80 °C, 4 h pre-dry[24][25][20] | Moderate — 0.46 % saturated at 25 °C / 55 % RH[3] |
| Equilibrium moisture content at ~50 % RH% | Not documented | 0.46 saturated at 25 °C / 55 % RH (Bambu Lab)[3] |
| Symptoms when wet | Bubbling and popping at the nozzle, stringing and a rough surface[26] | Not documented |
| Effect of moisture on strength | Polymaker rates ABS moderate-sensitivity and publishes no dry-versus-conditioned figures; absorbed water flashes to steam in the hotend and shows as bubbling and poor layer adhesion[26] | 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[26] |
| Storage requirement | Sealed with desiccant; Polymaker rates ABS moderate-sensitivity[26] | Not documented |
| Mechanical Properties | ||
| Tensile strength (XY)MPa | 46 at break (printed XY, ISO 527)[1] | 32 ± 3 printed XY, ISO 527 (Bambu Lab); colorFabb quotes 61.5 by ISO 527 on its own specimens[3][4] |
| Young's modulusMPa | 5210 (printed XY, ISO 527) — more than double unfilled ABS[1] | 2030 ± 210 printed XY, ISO 527 (Bambu Lab); colorFabb 2960[3][4] |
| Elongation at break% | 2 at break (printed XY, ISO 527)[1] | 8.6 ± 1.2 printed XY, ISO 527 (Bambu Lab); colorFabb 10.5 at break[3][4] |
| Flexural strengthMPa | 76 (printed XY, ISO 178)[1] | 76 ± 4 printed XY, ISO 178 (Bambu Lab)[3] |
| Flexural modulusMPa | 5260 (printed XY, ISO 178)[1] | 2640 ± 130 printed XY, ISO 178 (Bambu Lab); colorFabb 3295[3][4] |
| 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[3][4] |
| Other impact data | Not documented | Charpy unnotched 27.3 (Bambu Lab) and 30.8 (colorFabb), printed, ISO 179[3][4] |
| Layer adhesion / Z tensileMPa | Not documented | 26 ± 3 printed Z, ISO 527 (Bambu Lab)[3] |
| Brittleness1–5 | Brittle — snaps with little warning; elongation at break 2 %[1] | Brittle — snaps with little warning[3] |
| Creep resistance / sustained load1–5 | Good — no creep test found; chopped carbon fibre restrains matrix flow and modulus rises to 5210 MPa against 2200–2330 for unfilled ABS[1][24][25] | 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[27][28][29] |
| Fatigue / repeated-flex resistance1–5 | Below average — no S-N curve found; elongation at break falls to 2 % against 10.5 % for unfilled ABS[1][24] | 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[30][3] |
| Elasticity / flexibility1–5 | Rigid[1] | Rigid[3] |
| Z strength as % of XY% | Not documented | 81 by tensile, 72 by flexural (printed, Bambu Lab)[3] |

| HDT at 1.8 MPa°C | Not documented | 52 (ISO 75, 1.8 MPa)[3] |
| Glass transition (Tg)°C | 105 (DSC)[1] | 55 (DSC)[3] |
| Melting point / Vicat°C | Not documented | 155 peak melt (DSC); colorFabb quotes above 155 by ISO 3146-C[3][4] |
| Thermal expansion (CTE)µm/m·K | 19–25 along the print bead and 80–84 in the build direction at 30 °C (20 wt% CF, large-format printed, TMA)[31] | Not documented |
| Environment & Chemical | ||
| UV resistance1–5 | Not documented | Degrades within weeks outdoors[32] |

| Food contact | Not food safe — Polymaker cites potential chemical leaching[19] | Not documented |
| Biodegradability / compostability | Not biodegradable[19] | Not documented |
| Recyclability | Mechanically recyclable but not accepted in household plastic collection[19] | Not documented |
| Electrical & ESD properties | Surface resistance above 10⁹ ohm/sq — not static-dissipative (ASTM D257)[1] | Not documented |
| Health & Safety | ||
| Fume toxicity1–5 | High — hazardous VOC such as styrene; enclosure and filtration needed[34][17] | Low hazard — minimal VOC and particle emission[34] |
| VOC emission rateµg/min | 12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[34] | Not documented |
| Ultrafine-particle emission rateparticles/min | 2 × 10¹⁰ to 9 × 10¹⁰ median across all ABS printers, two orders of magnitude above PLA's ≈1 × 10⁸[34] | Not documented |
| Hazardous species emitted | Styrene dominates. Bambu Lab states ABS and ASA release harmful gases such as styrene at printing temperature, which can be toxic and cause dizziness or nausea[34][17] | Not documented |
| Ventilation / filtration requirement1–5 | Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[34][17] | None needed in a normal room[34] |
| Dust & fibre handling hazard | Carbon fibre is bound in the matrix; sanding dust should not be inhaled[1] | Not documented |
| Post-Processing | ||
| Sanding & machining | Sands well and takes filler before painting[19] | Not documented |
| Painting & finishing | Paints readily after light abrasion[19] | Not documented |
| Vapour / chemical smoothing | Acetone smoothing is blunted by the fibre — only the resin fraction dissolves[33] | Not documented |
| Support material pairing | HIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[35][17] | Support for PLA (Bambu Lab)[3] |
| Dimensional accuracy & detail | Not documented | Glow brightness rises with wall thickness; 0.2 mm nozzles are not usable[16] |
| Solvents & Solubility | ||
| Soluble in | Acetone dissolves the resin and leaves the fibre as sludge; MEK, THF, ethyl acetate and chlorinated solvents do the same.[36][33] | Chloroform dissolves the PLA matrix (10 % w/v, 2–4 h at 23 °C) and leaves the filler as loose sludge; laboratory reagent.[37] |
| Softened or crazed by | Petrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[36][38] | Acetone, ethyl acetate and toluene plasticise the matrix but dissolve <1 % even at 65 °C; acetone submersion crazes parts.[37][39] |
| Solvent welding & smoothing agent | Acetone vapour reaches only the resin fraction, so the fibre is left standing proud of the smoothed surface.[39][33] | Chloroform vapour attacks only the resin fraction, so the filler is left standing proud; no workshop-safe agent exists.[40][39] |
