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][14][17][20]4–12 at Polymaker's 50–150 mm/s on a 0.4 mm nozzle at 0.2 mm layer[3]
Warping tendency1–5None[1]Not documented

Abrasiveness1–5Non-abrasive[23][22]Non-abrasive[3]
Nozzle clog risk1–5Very low[22]Moderate — needs dry filament and a clean nozzle; Polymaker specifies a 55 °C dry for the PLA grade and warns brass nozzle life falls to about 9 h on the PA12 grade[3][4]
Heat-creep / jam sensitivity1–5Moderate — good heatbreak cooling needed; PLA softens below 60 °C[24]Not documented

Symptoms when wetBubbling and popping at the nozzle, stringing, rough surface and weak layers[25]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[25]Not a structural material; no dry-versus-conditioned data is published[25]
Storage requirementSealed with desiccant below 20 % RH; shelf life at ambient is long[19][21]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][26]Not documented
Young's modulusMPa2650 at 300 mm/s, 2878 at classic speed (printed XY, ISO 527)[1]Not documented
Elongation at break%15.1 at 300 mm/s, 21.5 at classic speed (printed XY, ISO 527)[1]Not documented
Flexural strengthMPa71.4 at 300 mm/s, 76.5 at classic speed (printed XY, ISO 178)[1]Not documented

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]Not documented
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][26]Not documented
Brittleness1–5Moderate[1]Not documented
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[27]Not documented
Creep resistance / sustained load1–5Poor — 12 mm bar sagged to 17.7 mm over 6 days at 1.25 kg[26]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)[28][24]Not documented
Elasticity / flexibility1–5Rigid[1]Not documented
Z strength as % of XY%74 at 300 mm/s, 81 at classic speed (printed)[1]Not documented
Thermal Properties
HDT at 0.45 MPa°C53 (ISO 75, 0.45 MPa)[1]43 (ISO 75, 0.45 MPa, PolySupport for PA12). Polymaker's sheet prints a higher figure at the higher load, which is physically inverted; treat both HDT numbers as approximate[4]
HDT at 1.8 MPa°C52 (ISO 75, 1.8 MPa)[1]53 (ISO 75, 1.8 MPa, PolySupport for PA12) — printed above the 0.45 MPa figure on Polymaker's own sheet, which cannot be right; treat both as approximate[4]
Glass transition (Tg)°C59 (DSC)[1]Not documented
Melting point / Vicat°C164 peak melt (DSC); crystallisation 96 °C, Vicat 61 °C[1]Vicat 171 (PolySupport for PA12, ISO 306)[4]
Continuous service temperature°C53 — loaded bars begin to move at this temperature[26]Not documented
Thermal expansion (CTE)µm/m·K96–99 for plain printed PLA (fibre Bragg grating, 25–50 °C); no grade-specific measurement published[29]Not documented
Flammability / UL 94Flammable; no UL 94 rating published by the major brands[19][2]Not documented
Environment & Chemical
UV resistance1–5Degrades within weeks outdoors[24][30]Not documented
Chemical resistanceGood against weak acids, oils and grease; poor against strong acids and alkalis[1]Not documented
Water / humidity resistance in service1–5Good — insoluble in water[19]Not documented
Food contactBase resin is food-contact grade, but printed layer grooves harbour bacteria; Prusa advises against food use[24]Not documented
Biodegradability / compostabilityIndustrially compostable only — needs sustained 55 °C; not home compostable[31][24]Not documented
RecyclabilityMechanically recyclable; not accepted in household plastic collection[31]Not documented
Electrical & ESD propertiesNot documentedSurface resistance above 10^13 ohm/sq (ASTM D257, THERMAX HTS2 and MTS1)[32][33]
Health & Safety
Fume toxicity1–5Low hazard — minimal VOC and particle emission[34]Low hazard — minimal VOC and particle emission; none of these materials was in the chamber study[34]
Ventilation / filtration requirement1–5None needed in a normal room[34]Open a window / occasional ventilation[34]
Post-Processing
Sanding & machiningWet sanding — dry sanding heats the surface by friction and smears it[30][24]Not documented
Gluing & solvent weldingCyanoacrylate for most joints; some grades partially dissolve and bond with acetone[24][35]Not documented
Vapour / chemical smoothingNo practical vapour smoothing — only chloroform, hot benzene or THF, which are laboratory-only[24]Not documented
Support material pairingPolySupport and PolyDissolve S1 (Polymaker)[1]This is the support material. Polymaker publishes an adhesion matrix per model material, from very good to unusable, because break-away supports only work against the polymer they were matched to[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.[36]None — break-away support is removed mechanically; 3DXTech lists no water or solvent route for it.[37]
Softened or crazed byAcetone, ethyl acetate and toluene plasticise it but dissolve <1 % even at 65 °C; submersion in acetone crazes and destroys parts.[36][38]Not documented
Solvent welding & smoothing agentChloroform vapour smooths and welds PLA at the cost of tensile strength; acetone does not smooth it at all.[39][38]None — there is no solvent to weld or smooth with.[37]
