| Bed temperature°C | 80–100 (Bambu Lab)[2] | 70–110 (3DXTech FluorX)[3] |
| Enclosure / chamber requirement1–5 | Enclosure recommended — Bambu Lab specifies a 45–60 °C chamber[2][10] | Enclosure required (passive)[3] |
| Recommended chamber temperature°C | 45–60 (Bambu Lab)[2] | Not documented |
| Part cooling fan | 0–80 % (Bambu Lab)[2] | Not documented |
| Bed surface & adhesion aid | Clean the plate and apply glue; Simplify3D also lists Kapton tape and ABS slurry[10][11] | Not documented |
| Maximum volumetric flow (mm³/s; see test conditions)mm³/s | 14 at Bambu Lab's 180 mm/s cap on a 0.4 mm nozzle at 0.2 mm layer[2][12] | Not documented |
| Warping tendency1–5 | Moderate — needs adhesion aid or draught shield; Bambu Lab positions the fibre as reducing warping[2] | High — enclosure needed for reliable large parts[3] |
| Bed-adhesion difficulty1–5 | Needs a specific surface plus adhesive[10] | 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[10] | Expert / industrial hardware only[3][4] |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Hardened steel required[10] | Brass fine indefinitely for unfilled grades[3] |
| Abrasiveness1–5 | Highly abrasive — standard GF composite[10] | Non-abrasive when unfilled[3] |
| Nozzle clog risk1–5 | Moderate — needs dry filament and a clean nozzle; 3DXTech specifies a hardened 0.4 mm minimum nozzle and 0.25 mm layers or higher for the glass-filled grade[14][15] | Low — 3DXTech lists no special nozzle concerns, no minimum layer height and states drying is not required[9] |
| Heat-creep / jam sensitivity1–5 | Slightly sensitive[11] | Not documented |
| Hotend requirement | No special hot-end required[11] | 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[4] |
| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | Moderate — 0.53 % saturated at 25 °C / 55 % RH (Bambu Lab)[2] | Negligible (<0.1 % EMC) — fluoropolymers are essentially non-hygroscopic[3] |
| Equilibrium moisture content at ~50 % RH% | 0.53 saturated at 25 °C / 55 % RH (Bambu Lab)[2] | Not documented |
| Drying temperature & time | 80 °C for 8 h (Bambu Lab)[2] | Not documented |
| Symptoms when wet | Bubbling and popping at the nozzle, stringing and a rough surface[16] | 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[16] | Not applicable in practice — 3DXTech states drying is not required for PVDF, so there is no moisture-driven strength loss to measure[9] |
| Storage requirement | Sealed with desiccant; Polymaker rates ABS moderate-sensitivity[16] | Not documented |
| Mechanical Properties | ||
| Tensile strength (XY)MPa | 36 ± 3 printed XY, ISO 527 (Bambu Lab); 3DXTech quotes 68 at break[2][1] | 51 at break (printed XY, ISO 527)[3] |
| Young's modulusMPa | 3160 ± 170 printed XY, ISO 527 (Bambu Lab); 3DXTech quotes 4210[2][1] | 2450 (printed XY, ISO 527)[3] |

| Layer adhesion / Z tensileMPa | 29 ± 3 printed Z, ISO 527 (Bambu Lab)[2] | Not documented |
| Brittleness1–5 | Brittle — snaps with little warning; notched Charpy falls from 21.5 to 4.2 kJ/m² against unfilled Bambu Lab ABS[2][18] | Tough — absorbs impact, yields before breaking[3] |
| Hardness (scale-specific)Shore A / Shore D / Rockwell | Not documented | Rockwell M79 on extruded PVDF stock (ASTM D785)[17] |
| Creep resistance / sustained load1–5 | Good — no creep test found; chopped glass fibre lifts modulus to 3160 MPa against 2200 for unfilled Bambu Lab ABS[2][18] | Not documented |
| Fatigue / repeated-flex resistance1–5 | Below average — no S-N curve found; notched Charpy falls to 4.2 kJ/m² against 21.5 for unfilled Bambu Lab ABS[2][18] | Not documented |
| Elasticity / flexibility1–5 | Rigid[2] | Slightly flexible in thin sections[3] |
| Z strength as % of XY% | 81 (Bambu Lab, printed Z against XY tensile)[2] | Not documented |
| Thermal Properties | ||

| HDT at 1.8 MPa°C | 88 (ISO 75, 1.8 MPa, Bambu Lab) against 84 for unfilled Bambu Lab ABS[2][18] | 113 on extruded PVDF stock (ASTM D648 at 264 psi; converted from 235 °F)[17] |

| 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[17] |
| Flammability / UL 94 | Not documented | UL 94 V-0 on extruded PVDF stock; Ensinger lists inherent flame resistance[17] |
| Environment & Chemical | ||
| UV resistance1–5 | Not documented | Excellent — designed for permanent outdoor use; Ensinger lists good UV and weather resistance and high gamma radiation resistance for PVDF stock[3][17] |
| Chemical resistance | Good against weak acids, weak alkalis, oils and grease; dissolved by acetone[19] | Outstanding — resistant to most acids, solvents and oxidising agents, which is the reason to use it[3] |
| Water / humidity resistance in service1–5 | Not documented | Excellent — essentially unaffected[3] |
| Food contact | Not food safe — Polymaker cites potential chemical leaching[13] | Not documented |
| Biodegradability / compostability | Not biodegradable[13] | Not documented |
| Recyclability | Mechanically recyclable but not accepted in household plastic collection[13] | Not documented |
| Health & Safety | ||
| Fume toxicity1–5 | High — hazardous VOC such as styrene; enclosure and filtration needed[20][10] | Very high — toxic decomposition products; local exhaust mandatory. Above 315 °C thermal decomposition yields hydrofluoric acid, hydrogen cyanide and carbon monoxide[4] |
| VOC emission rateµg/min | 12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[20] | 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[20] | 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[20][10] | 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[4] |
| Ventilation / filtration requirement1–5 | Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[20][10] | Local exhaust to outside / fume hood — the SDS states local exhaust is preferred[4] |
| Dust & fibre handling hazard | Glass fibre is bound in the matrix; avoid inhaling sanding dust[1] | 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[4] |
| Post-Processing | ||
| Sanding & machining | Sands well and takes filler before painting[13] | Not documented |
| Painting & finishing | Paints readily after light abrasion[13] | Not documented |
| Support material pairing | HIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[21][10] | Not documented |
| Dimensional accuracy & detail | Bambu Lab describes a smooth matte finish with micro-spot gloss that blurs layer lines[2] | The processing window sits well below the 315 °C decomposition threshold, so nozzle temperature must be controlled rather than raised to chase flow[3][4] |
| Solvents & Solubility | ||
| Soluble in | Acetone dissolves the resin and leaves the fibre as sludge; MEK, THF, ethyl acetate and chlorinated solvents do the same.[22][19] | THF, MEK, DMF, DMAc, NMP, DMSO and trimethyl phosphate dissolve 5–10 wt% at ambient — Arkema's active solvents, all lab reagents.[23] |
| Softened or crazed by | Petrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[22][24] | Acetone, MIBK, cyclohexanone, butyl acetate and glycol ethers swell it; alkalis above pH 12 attack the homopolymer.[23][25] |
| Solvent welding & smoothing agent | Acetone vapour reaches only the resin fraction, so the fibre is left standing proud of the smoothed surface.[26][19] | None for the workshop — the active solvents (NMP, DMAc, DMF) are laboratory reagents used for casting membranes, not joints.[23] |
