| Bed temperature°C | 80–100 (Bambu Lab)[1] | 70–110 (3DXTech FluorX)[4] |
| Enclosure / chamber requirement1–5 | Enclosure recommended — Bambu Lab specifies a 45–60 °C chamber[1][12] | Enclosure required (passive)[4] |
| Recommended chamber temperature°C | 45–60 (Bambu Lab)[1] | Not documented |
| Part cooling fan | Fan on (Bambu Lab)[1] | Not documented |
| Bed surface & adhesion aid | PEI sheet, BuildTak or an adhesion aid such as Magigoo (Polymaker); Simplify3D also lists Kapton tape and ASA slurry[13][14] | Not documented |
| Maximum volumetric flow (mm³/s; see test conditions)mm³/s | 20 at Bambu Lab's 250 mm/s cap on a 0.4 mm nozzle at 0.2 mm layer[1][15] | Not documented |
| Warping tendency1–5 | Moderate — needs adhesion aid or draught shield; the fibre reduces warping against unfilled ASA[12] | High — enclosure needed for reliable large parts[4] |
| Bed-adhesion difficulty1–5 | Needs a specific surface plus adhesive[13] | Not documented |
| Stringing / oozing tendency1–5 | Slight — Polymaker advises 1–2 mm retraction at 20–30 mm/s[13] | Not documented |
| Overall printing difficulty1–5 | Intermediate — dry filament and a tuned profile; hardened nozzle mandatory[12] | Expert / industrial hardware only[4][5] |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Hardened steel required[12] | Brass fine indefinitely for unfilled grades[4] |
| Abrasiveness1–5 | Highly abrasive — standard CF composite[12] | Non-abrasive when unfilled[4] |
| Nozzle clog risk1–5 | Moderate — needs dry filament and a clean nozzle; Prusa lists higher risk of nozzle clogging for fibre-filled composites and Simplify3D a higher tendency to clog[16][17] | Low — 3DXTech lists no special nozzle concerns, no minimum layer height and states drying is not required[11] |
| Heat-creep / jam sensitivity1–5 | Slightly sensitive[14] | Not documented |
| Hotend requirement | No special hotend required[14] | Not documented |
| Other hardware wear | Not documented | Hydrogen fluoride released on overheating is extremely corrosive and will attack hotend and enclosure metalwork as well as people[5] |
| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | Moderate — 0.33 % saturated at 25 °C / 55 % RH (Bambu Lab)[1] | Negligible (<0.1 % EMC) — fluoropolymers are essentially non-hygroscopic[4] |
| Equilibrium moisture content at ~50 % RH% | 0.33 saturated at 25 °C / 55 % RH (Bambu Lab)[1] | Not documented |
| Drying temperature & time | 80 °C for 8 h (Bambu Lab)[1] | Not documented |
| Symptoms when wet | Bubbling and popping at the nozzle, stringing and a rough surface[18] | Not documented |
| Effect of moisture on strength | No dry-versus-conditioned figures are published; Polymaker groups the styrenics as moderate-sensitivity and absorbed water shows as bubbling and poor layer adhesion[18] | Not applicable in practice — 3DXTech states drying is not required for PVDF, so there is no moisture-driven strength loss to measure[11] |
| Storage requirement | Sealed with desiccant; Polymaker rates the styrenics moderate-sensitivity[18] | Not documented |
| Mechanical Properties | ||
| Tensile strength (XY)MPa | 34 ± 3 printed XY, ISO 527 (Bambu Lab); 3DXTech quotes 48 at break and Formfutura 79 at 23 °C[1][2][3] | 51 at break (printed XY, ISO 527)[4] |
| Young's modulusMPa | 4200 ± 270 printed XY, ISO 527 (Bambu Lab); 3DXTech quotes 5355 and Formfutura 7580[1][2][3] | 2450 (printed XY, ISO 527)[4] |

| Hardness (scale-specific)Shore A / Shore D / Rockwell | Not documented | Rockwell M79 on extruded PVDF stock (ASTM D785)[20] |
| Creep resistance / sustained load1–5 | Good — no creep test found; chopped carbon fibre lifts modulus to 4200 MPa against 2379–2450 for unfilled ASA[1][21] | Not documented |
| Fatigue / repeated-flex resistance1–5 | Below average — no CF-grade S-N curve; notched Charpy falls to 6.2 kJ/m² against 19.6 for unfilled Bambu Lab ASA[1][19] | Not documented |
| Elasticity / flexibility1–5 | Rigid[1] | Slightly flexible in thin sections[4] |
| Z strength as % of XY% | 88 by tensile, 46 by flexural (printed, Bambu Lab)[1] | Not documented |
| Thermal Properties | ||
| HDT at 0.45 MPa°C | 110 (ISO 75, 0.45 MPa, Bambu Lab) against 100 for unfilled Bambu Lab ASA[1][19] | 149 on extruded PVDF stock (ASTM D648 at 66 psi; converted from 300 °F)[20] |
| HDT at 1.8 MPa°C | 102 (ISO 75, 1.8 MPa, Bambu Lab) against 92 for unfilled Bambu Lab ASA[1][19] | 113 on extruded PVDF stock (ASTM D648 at 264 psi; converted from 235 °F)[20] |
| Melting point / Vicat°C | Not documented | 170 melting (ISO 11357)[4] |

| Thermal expansion (CTE)µm/m·K | Not documented | 127.8 (extruded PVDF stock, ASTM D696; source states 7.1e-5 in/in/°F) — the highest thermal expansion of any engineering polymer in this dataset[20] |
| Flammability / UL 94 | Flammable; no UL 94 rating published[19] | UL 94 V-0 on extruded PVDF stock; Ensinger lists inherent flame resistance[20] |
| Environment & Chemical | ||
| UV resistance1–5 | Excellent — designed for permanent outdoor use; the acrylate rubber phase is unchanged by the fibre[23][13] | Excellent — designed for permanent outdoor use; Ensinger lists good UV and weather resistance and high gamma radiation resistance for PVDF stock[4][20] |
| Chemical resistance | Good against weak acids, weak alkalis, oils and grease; dissolved by acetone[21] | Outstanding — resistant to most acids, solvents and oxidising agents, which is the reason to use it[4] |
| Water / humidity resistance in service1–5 | Not documented | Excellent — essentially unaffected[4] |
| Food contact | Not food safe[13] | Not documented |
| Biodegradability / compostability | Not biodegradable[13] | Not documented |
| Recyclability | Not accepted in household plastic collection[13] | Not documented |
| Electrical & ESD properties | Surface resistance above 10⁹ ohm/sq — not static-dissipative (3DXTech, ASTM D257)[2] | Not documented |
| Health & Safety | ||
| Fume toxicity1–5 | High — hazardous VOC such as styrene; enclosure and filtration needed[24][12] | Very high — toxic decomposition products; local exhaust mandatory. Above 315 °C thermal decomposition yields hydrofluoric acid, hydrogen cyanide and carbon monoxide[5] |
| Hazardous species emitted | Styrene. Bambu Lab states ABS and ASA release harmful gases such as styrene at printing temperature, which can be toxic and cause dizziness or nausea. Azimi et al. measured styrene from every styrenic filament tested but did not test ASA itself[12][24] | Above 315 °C: hydrofluoric acid, hydrogen cyanide, phenols, carbon monoxide, carbon dioxide and dense smoke. HF is extremely corrosive, its skin burns may not be immediately visible or painful, and exposure can be fatal by skin absorption, inhalation or ingestion[5] |
| Ventilation / filtration requirement1–5 | Enclosure with carbon and HEPA filtration[24][12] | Local exhaust to outside / fume hood — the SDS states local exhaust is preferred[5] |
| Dust & fibre handling hazard | Carbon fibre is bound in the matrix; sanding dust should not be inhaled[2] | Molten polymer causes thermal burns and must not be pulled off the skin. If HF is detected during a decomposition event, cut the heat but keep the extraction running, ventilate, and clear non-essential people from the area[5] |
| Post-Processing | ||
| Sanding & machining | Sands well and takes filler before painting[13] | Not documented |
| Painting & finishing | Paints readily; ASA holds colour outdoors so many parts are left unpainted[13] | Not documented |
| Gluing & solvent welding | Solvent-welds with acetone[21] | Not documented |
| Vapour / chemical smoothing | Acetone vapour smoothing works[21] | Not documented |
| Support material pairing | HIPS breaks away or dissolves in d-limonene; Bambu Lab sells a Support for ABS that also serves ASA[12] | Not documented |
| Dimensional accuracy & detail | Matte fibre-filled finish hides layer lines[1] | The processing window sits well below the 315 °C decomposition threshold, so nozzle temperature must be controlled rather than raised to chase flow[4][5] |
| Solvents & Solubility | ||
| Soluble in | Acetone dissolves the resin and leaves the fibre; MEK, THF, ethyl acetate and chlorinated solvents attack the styrenic backbone.[25][21] | THF, MEK, DMF, DMAc, NMP, DMSO and trimethyl phosphate dissolve 5–10 wt% at ambient — Arkema's active solvents, all lab reagents.[26] |
| Softened or crazed by | Limonene attacks some grades — Prusa reports Prusament ASA Orange flaking apart as layer adhesion fails.[27] | Acetone, MIBK, cyclohexanone, butyl acetate and glycol ethers swell it; alkalis above pH 12 attack the homopolymer.[26][28] |
| Solvent welding & smoothing agent | Acetone vapour reaches only the resin fraction, so the fibre is left standing proud of the smoothed surface.[29][21] | None for the workshop — the active solvents (NMP, DMAc, DMF) are laboratory reagents used for casting membranes, not joints.[26] |
