Typical applicationsLarge or repetitive prints on printers that can sustain high flow[15][12]Chemical-plant fittings, semiconductor handling and parts needing outstanding UV and chemical resistance[3]
Diameter tolerance± mm±0.03 (Bambu Lab PLA Basic, rated to 258 mm/s)[16]Not documented
Printing Parameters
Nozzle temperature°C210–230 for high-speed work; 190–210 at classic speeds[1][12]Not documented
Bed temperature°C30–60 (Polymaker); 35–45 (Bambu Lab)[1][17]70–110 (3DXTech FluorX)[3]
Enclosure / chamber requirement1–5Open frame is fine[1]Enclosure required (passive)[3]
Part cooling fanFan on[1]Not documented
Maximum volumetric flow (mm³/s; see test conditions)mm³/s≈24 at 300 mm/s with a 0.4 mm nozzle and 0.2 mm layer; 30 % more flow than regular PLA at the same temperature[1][12][15][18]Not documented
Warping tendency1–5None[1]High — enclosure needed for reliable large parts[3]
Bed-adhesion difficulty1–5Sticks to anything[19]Not documented
Overall printing difficulty1–5Easy — minor profile tuning; needs a printer that can actually reach the flow rate[12][1]Expert / industrial hardware only[3][4]
Hardware Wear & Reliability
Nozzle hardness required1–4Brass fine indefinitely[20]Brass fine indefinitely for unfilled grades[3]
Abrasiveness1–5Non-abrasive[21][20]Non-abrasive when unfilled[3]
Nozzle clog risk1–5Very low[20]Low — 3DXTech lists no special nozzle concerns, no minimum layer height and states drying is not required[14]
Heat-creep / jam sensitivity1–5Moderate — good heatbreak cooling needed; PLA softens below 60 °C[22]Not documented
Hotend requirementNo special hot-end required[19]Not documented
Other hardware wearNot documentedHydrogen fluoride released on overheating is extremely corrosive and will attack hotend and enclosure metalwork as well as people[4]
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5Moderate — 0.40 % equilibrium at 23 °C / 70 % RH[1]Negligible (<0.1 % EMC) — fluoropolymers are essentially non-hygroscopic[3]
Equilibrium moisture content at ~50 % RH%0.40 equilibrium at 23 °C / 70 % RH (Polymaker PolySonic)[1]Not documented
Drying temperature & time55 °C for 6 h; 50 °C for 8 h (Bambu Lab)[1][17]Not documented
Symptoms when wetBubbling and popping at the nozzle, stringing, rough surface and weak layers[23]Not documented
Effect of moisture on strengthPolymaker rates PLA low-sensitivity — the loss shows as poor layer adhesion and brittle layers rather than a published strength figure[23]Not applicable in practice — 3DXTech states drying is not required for PVDF, so there is no moisture-driven strength loss to measure[14]
Storage requirementSealed with desiccant below 20 % RH; shelf life at ambient is long[17][19]Not documented
Mechanical Properties
Tensile strength (XY)MPa43.9 at 300 mm/s and 46.0 at 46.7 mm/s (printed XY, ISO 527); 58.6 on My Tech Fun bars for Creality Hyper PLA[1][24]51 at break (printed XY, ISO 527)[3]

Charpy impact, notchedkJ/m²5.0 at 300 mm/s, 6.1 at classic speed (printed XY, ISO 179, notched)[1]Not documented
Other impact dataPrinting at 300 mm/s instead of 46.7 mm/s costs 4.6 % tensile strength and 18 % notched Charpy[1]Izod 133 J/m on extruded PVDF stock, converted from 2.49 ft-lb/in (ASTM D256)[25]
Layer adhesion / Z tensileMPa32.4 at 300 mm/s, 37.3 at classic speed (printed Z, ISO 527); 35.3 for Creality Hyper PLA vs 23.0 for average PLA on identical bars[1][24]Not documented
Brittleness1–5Moderate[1]Tough — absorbs impact, yields before breaking[3]
Hardness (scale-specific)Shore A / Shore D / Rockwell78.7 Shore D measured on printed bars for Sunlu PLA Meta (My Tech Fun), against 75.3 for the same maker's plain PLA[26]Rockwell M79 on extruded PVDF stock (ASTM D785)[25]
Creep resistance / sustained load1–5Poor — 12 mm bar sagged to 17.7 mm over 6 days at 1.25 kg[24]Not documented
Fatigue / repeated-flex resistance1–5Poor — no grade-specific S-N curve; plain printed PLA ran 38 000–49 000 cycles at 30 % of tensile strength (R = 0.2)[27][22]Not documented
Elasticity / flexibility1–5Rigid[1]Slightly flexible in thin sections[3]

Flammability / UL 94Flammable; no UL 94 rating published by the major brands[17][2]UL 94 V-0 on extruded PVDF stock; Ensinger lists inherent flame resistance[25]
Environment & Chemical
UV resistance1–5Degrades within weeks outdoors[22][29]Excellent — designed for permanent outdoor use; Ensinger lists good UV and weather resistance and high gamma radiation resistance for PVDF stock[3][25]
Chemical resistanceGood against weak acids, oils and grease; poor against strong acids and alkalis[1]Outstanding — resistant to most acids, solvents and oxidising agents, which is the reason to use it[3]
Water / humidity resistance in service1–5Good — insoluble in water[17]Excellent — essentially unaffected[3]
Food contactBase resin is food-contact grade, but printed layer grooves harbour bacteria; Prusa advises against food use[22]Not documented
Biodegradability / compostabilityIndustrially compostable only — needs sustained 55 °C; not home compostable[30][22]Not documented
RecyclabilityMechanically recyclable; not accepted in household plastic collection[30]Not documented
Health & Safety
Fume toxicity1–5Low hazard — minimal VOC and particle emission[31]Very high — toxic decomposition products; local exhaust mandatory. Above 315 °C thermal decomposition yields hydrofluoric acid, hydrogen cyanide and carbon monoxide[4]
Hazardous species emittedNot documentedAbove 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 requirement1–5None needed in a normal room[31]Local exhaust to outside / fume hood — the SDS states local exhaust is preferred[4]
Dust & fibre handling hazardNot documentedMolten 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 & machiningWet sanding — dry sanding heats the surface by friction and smears it[29][22]Not documented
Gluing & solvent weldingCyanoacrylate for most joints; some grades partially dissolve and bond with acetone[22][32]Not documented
Vapour / chemical smoothingNo practical vapour smoothing — only chloroform, hot benzene or THF, which are laboratory-only[22]Not documented
Support material pairingPolySupport and PolyDissolve S1 (Polymaker)[1]Not documented
Dimensional accuracy & detailNot documentedThe 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 inChloroform: 10 % w/v in 2–4 h at 23 °C, every grade and morphology; THF and DMF only at 65 °C. Laboratory reagents.[33]THF, MEK, DMF, DMAc, NMP, DMSO and trimethyl phosphate dissolve 5–10 wt% at ambient — Arkema's active solvents, all lab reagents.[34]
Softened or crazed byAcetone, ethyl acetate and toluene plasticise it but dissolve <1 % even at 65 °C; submersion in acetone crazes and destroys parts.[33][35]Acetone, MIBK, cyclohexanone, butyl acetate and glycol ethers swell it; alkalis above pH 12 attack the homopolymer.[34][36]
Solvent welding & smoothing agentChloroform vapour smooths and welds PLA at the cost of tensile strength; acetone does not smooth it at all.[37][35]None for the workshop — the active solvents (NMP, DMAc, DMF) are laboratory reagents used for casting membranes, not joints.[34]
