| Identity & Market | ||
| Base polymer / chemistry | ABS with a flame-retardant package; 3DXTech rates the base resin UL 94 V-0[1] | Polyvinylidene fluoride — a semi-crystalline fluoropolymer[2][3] |
| Densityg/cm³ | 1.18 (ISO 1183) — above unfilled ABS at 1.05 because of the retardant loading[1][4] | 1.71 (ISO 1183) — the densest unfilled filament in the dataset[2] |
| Typical priceUSD/kg | 1 kg-equivalent spools span 45–120; the middle of the market is about 52[5][6][7][8] | 1 kg-equivalent spools cluster near 251[5] |
| Price range across brandsUSD/kg | 45–120 across brands; SUNLU 45, YXPOLYER 50, Coex 3D 52, 3DXTech 107 at 750 g pricing; the FR PC/ABS grade runs 120[5][6][7][8] | 251 at 3DXTech's 750 g pricing — the most expensive material in the whole dataset[5] |
| Market availability1–5 | Niche, a handful of specialist brands[5] | Special order, 1–2 makers worldwide[5][9] |
| Spool sizes & diameters | 1.75 and 2.85 mm; 750 g spools[5] | 1.75 and 2.85 mm; 750 g spools[5] |
| Typical applications | Electrical enclosures and transport interiors that must meet a flammability rating[1] | Chemical-plant fittings, semiconductor handling and parts needing outstanding UV and chemical resistance[2] |
| Printing Parameters | ||
| Bed temperature°C | Not documented | 70–110 (3DXTech FluorX)[2] |
| Enclosure / chamber requirement1–5 | Enclosure recommended[10] | Enclosure required (passive)[2] |
| Bed surface & adhesion aid | Clean the plate and apply glue; Simplify3D also lists Kapton tape and ABS slurry[10][11] | Not documented |
| Warping tendency1–5 | High — enclosure needed for reliable large parts[10] | High — enclosure needed for reliable large parts[2] |
| 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[12] | Not documented |
| Overall printing difficulty1–5 | Intermediate — dry filament and a tuned profile[10] | Expert / industrial hardware only[2][3] |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Brass fine indefinitely[10] | Brass fine indefinitely for unfilled grades[2] |
| Abrasiveness1–5 | Non-abrasive[1] | Non-abrasive when unfilled[2] |
| Nozzle clog risk1–5 | Low — 3DXTech lists no special nozzle concerns and no minimum layer height for its FR-ABS, only an 80 °C pre-dry[13] | 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[3] |
| 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[4][14][13] | Negligible (<0.1 % EMC) — fluoropolymers are essentially non-hygroscopic[2] |
| Symptoms when wet | Bubbling and popping at the nozzle, stringing and a rough surface[15] | 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[15] | 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[15] | Not documented |
| Mechanical Properties | ||
| Tensile strength (XY)MPa | 45 at break (printed XY, ISO 527)[1] | 51 at break (printed XY, ISO 527)[2] |
| Young's modulusMPa | 1990 (printed XY, ISO 527)[1] | 2450 (printed XY, ISO 527)[2] |
| Elongation at break% | 4 at break (printed XY, ISO 527) — well below the 10 % of unfilled 3DXTech ABS[1][16] | 25 at break (printed XY, ISO 527)[2] |
| Flexural strengthMPa | 80 (printed XY, ISO 178)[1] | 50 (printed XY, ISO 178)[2] |
| Flexural modulusMPa | 2250 (printed XY, ISO 178)[1] | 1800 (printed XY, ISO 178)[2] |
| Other impact data | Not documented | Izod 133 J/m on extruded PVDF stock, converted from 2.49 ft-lb/in (ASTM D256)[17] |
| Brittleness1–5 | Moderate — elongation at break falls to 4 % from 10 % for the unfilled grade[1][16] | Tough — absorbs impact, yields before breaking[2] |
| Hardness (scale-specific)Shore A / Shore D / Rockwell | Not documented | Rockwell M79 on extruded PVDF stock (ASTM D785)[17] |
| Creep resistance / sustained load1–5 | Moderate — no creep test found; Tg of 105 °C keeps room-temperature service far below softening[1][16] | Not documented |
| Fatigue / repeated-flex resistance1–5 | Below average — no S-N curve found; elongation at break falls to 4 % against 10 % for unfilled 3DXTech ABS[1][16] | Not documented |
| Elasticity / flexibility1–5 | Rigid[1] | Slightly flexible in thin sections[2] |
| Thermal Properties | ||
| HDT at 0.45 MPa°C | Not documented | 149 on extruded PVDF stock (ASTM D648 at 66 psi; converted from 300 °F)[17] |
| HDT at 1.8 MPa°C | Not documented | 113 on extruded PVDF stock (ASTM D648 at 264 psi; converted from 235 °F)[17] |
| Glass transition (Tg)°C | 105 (DSC)[1] | Not documented |
| Melting point / Vicat°C | Not documented | 170 melting (ISO 11357)[2] |
| Continuous service temperature°C | Not documented | 149 long term and short term on extruded PVDF stock (converted from 300 °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 | UL 94 V-0 at 1.5 mm, rated on the base resin rather than the printed part[1] | 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[2][17] |
| Chemical resistance | Good against weak acids, weak alkalis, oils and grease; dissolved by acetone[18] | Outstanding — resistant to most acids, solvents and oxidising agents, which is the reason to use it[2] |
| Water / humidity resistance in service1–5 | Not documented | Excellent — essentially unaffected[2] |
| Food contact | Not food safe — Polymaker cites potential chemical leaching[12] | Not documented |
| Biodegradability / compostability | Not biodegradable[12] | Not documented |
| Recyclability | Mechanically recyclable but not accepted in household plastic collection[12] | Not documented |
| Health & Safety | ||
| Fume toxicity1–5 | High — hazardous VOC such as styrene; enclosure and filtration needed[19][10] | Very high — toxic decomposition products; local exhaust mandatory. Above 315 °C thermal decomposition yields hydrofluoric acid, hydrogen cyanide and carbon monoxide[3] |
| VOC emission rateµg/min | 12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[19] | 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[19] | 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[19][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[3] |
| Ventilation / filtration requirement1–5 | Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[19][10] | Local exhaust to outside / fume hood — the SDS states local exhaust is preferred[3] |
| Dust & fibre handling hazard | Not documented | 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[3] |
| Post-Processing | ||
| Sanding & machining | Sands well and takes filler before painting[12] | Not documented |
| Painting & finishing | Paints readily after light abrasion[12] | Not documented |
| Support material pairing | HIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[20][10] | Not documented |
| Dimensional accuracy & detail | Not documented | The processing window sits well below the 315 °C decomposition threshold, so nozzle temperature must be controlled rather than raised to chase flow[2][3] |
| Solvents & Solubility | ||
| Soluble in | Acetone dissolves it — the basis of ABS slurry; so do MEK, THF, ethyl acetate, chloroform, dichloromethane and toluene.[21][18] | THF, MEK, DMF, DMAc, NMP, DMSO and trimethyl phosphate dissolve 5–10 wt% at ambient — Arkema's active solvents, all lab reagents.[22] |
| Softened or crazed by | Petrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[21][23] | Acetone, MIBK, cyclohexanone, butyl acetate and glycol ethers swell it; alkalis above pH 12 attack the homopolymer.[22][24] |
| Solvent welding & smoothing agent | Acetone: about 20 min of vapour at 80 °C over 5 mm of liquid. Prusa measured layer adhesion more than doubled.[25] | None for the workshop — the active solvents (NMP, DMAc, DMF) are laboratory reagents used for casting membranes, not joints.[22] |
