| Spool sizes & diameters | 1.75 mm; 1 kg spools[2] | 1.75 mm; 1 kg spools[5][7] |
| Typical applications | Tough, chemically resistant functional parts; Prusa targets it at impact-loaded and vibration-loaded components[2] | Large or repetitive prints on printers that can sustain high flow[13][11] |
| Diameter tolerance± mm | ±0.02 (Prusament)[1] | ±0.03 (Bambu Lab PLA Basic, rated to 258 mm/s)[14] |
| Printing Parameters | ||
| Nozzle temperature°C | 275 ± 10 (Prusament)[1] | 210–230 for high-speed work; 190–210 at classic speeds[3][11] |
| Bed temperature°C | 100 ± 10 (Prusament)[1] | 30–60 (Polymaker); 35–45 (Bambu Lab)[3][15] |
| Enclosure / chamber requirement1–5 | Enclosure required (passive) — Prusament specifies a 55 ± 5 °C chamber[1] | Open frame is fine[3] |
| Recommended chamber temperature°C | 55 ± 5 (Prusament)[1] | Not documented |
| Part cooling fan | Not documented | Fan on[3] |
| Bed surface & adhesion aid | PA nylon sheet (Prusament)[1] | Not documented |
| Maximum volumetric flow (mm³/s; see test conditions)mm³/s | Not documented | ≈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[3][11][13][16] |
| Warping tendency1–5 | Not documented | None[3] |
| Bed-adhesion difficulty1–5 | Not documented | Sticks to anything[17] |
| Overall printing difficulty1–5 | Advanced — enclosure, hardware upgrades, tuning[1][18] | Easy — minor profile tuning; needs a printer that can actually reach the flow rate[11][3] |
| Extruder requirement | Prusa printed its test specimens with a high-flow CHT nozzle[1] | Not documented |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Brass fine indefinitely for unfilled grades[18] | Brass fine indefinitely[19] |
| Abrasiveness1–5 | Non-abrasive when unfilled[18] | Non-abrasive[20][19] |
| Nozzle clog risk1–5 | High — jams from moisture, heat creep or particles[21] | Very low[19] |
| Heat-creep / jam sensitivity1–5 | Not documented | Moderate — good heatbreak cooling needed; PLA softens below 60 °C[22] |
| Hotend requirement | Not documented | No special hot-end required[17] |
| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | High (0.8–2 %) — Prusa measures 0.46 % after 7 days at 22 % RH, but PA11 sits between PA12 and PA6 in the family[1][21] | Moderate — 0.40 % equilibrium at 23 °C / 70 % RH[3] |
| Equilibrium moisture content at ~50 % RH% | 0.26 after 24 h and 0.46 after 7 days (Prusa Polymers method)[1] | 0.40 equilibrium at 23 °C / 70 % RH (Polymaker PolySonic)[3] |
| Drying temperature & time | Not documented | 55 °C for 6 h; 50 °C for 8 h (Bambu Lab)[3][15] |
| Symptoms when wet | Popping and cracking during extrusion, then hard-to-diagnose defects[23] | Bubbling and popping at the nozzle, stringing, rough surface and weak layers[21] |
| Effect of moisture on strength | Prusa publishes no dry-versus-conditioned columns; the CoPA reference shows the PA-family response — stiffness and strength fall sharply, impact and elongation rise[23][24] | Polymaker rates PLA low-sensitivity — the loss shows as poor layer adhesion and brittle layers rather than a published strength figure[21] |
| Storage requirement | Sealed below 20 % RH with desiccant[21] | Sealed with desiccant below 20 % RH; shelf life at ambient is long[15][17] |
| Mechanical Properties | ||
| Tensile strength (XY)MPa | 38.3 ± 0.8 printed horizontal and 39.5 ± 0.5 printed vertical at yield, ISO 527-1[1] | 43.9 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[3][25] |

| Layer adhesion / Z tensileMPa | 32 ± 1 (Prusa Polymers interlayer adhesion test) — the highest interlayer figure Prusa publishes for any of its filaments[1] | 32.4 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[3][25] |
| Brittleness1–5 | Tough — absorbs impact, yields before breaking[1] | Moderate[3] |
| Hardness (scale-specific)Shore A / Shore D / Rockwell | 70 Shore D (Prusa Polymers method)[1] | 78.7 Shore D measured on printed bars for Sunlu PLA Meta (My Tech Fun), against 75.3 for the same maker's plain PLA[26] |

| Fatigue / repeated-flex resistance1–5 | Excellent — living hinges viable[18] | Poor — 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] |
| Elasticity / flexibility1–5 | Semi-flexible[1] | Rigid[3] |
| Z strength as % of XY% | 84 — Prusa publishes a tensile anisotropy coefficient of 0.84, the ratio of Z to XY tensile strength[1] | 74 at 300 mm/s, 81 at classic speed (printed)[3] |

| HDT at 1.8 MPa°C | 49.9 (ISO 75, 1.8 MPa)[1] | 52 (ISO 75, 1.8 MPa)[3] |

| Melting point / Vicat°C | Not documented | 164 peak melt (DSC); crystallisation 96 °C, Vicat 61 °C[3] |

| Thermal expansion (CTE)µm/m·K | Not documented | 96–99 for plain printed PLA (fibre Bragg grating, 25–50 °C); no grade-specific measurement published[28] |
| Flammability / UL 94 | Not documented | Flammable; no UL 94 rating published by the major brands[15][4] |
| Environment & Chemical | ||
| UV resistance1–5 | Not documented | Degrades within weeks outdoors[22][29] |

| Water / humidity resistance in service1–5 | Absorbs water, properties shift[23] | Good — insoluble in water[15] |
| Food contact | Not documented | Base resin is food-contact grade, but printed layer grooves harbour bacteria; Prusa advises against food use[22] |
| Biodegradability / compostability | Bio-based — the monomer comes from castor oil[2] | Industrially compostable only — needs sustained 55 °C; not home compostable[30][22] |
| Recyclability | Not documented | Mechanically recyclable; not accepted in household plastic collection[30] |
| Health & Safety | ||
| Fume toxicity1–5 | Moderate — measurable VOCs and UFPs, ventilation advised[31] | Low hazard — minimal VOC and particle emission[31] |
| VOC emission rateµg/min | Up to 180 caprolactam, the dominant VOC from nylon; total VOC reached nearly 200 µg/min, the highest of the nine filaments tested[31] | Not documented |
| Ultrafine-particle emission rateparticles/min | ≈2 × 10⁸ median — low for ultrafine particles despite the highest VOC mass of any filament tested[31] | Not documented |

| Ventilation / filtration requirement1–5 | Ventilated room or enclosure recommended[31] | None needed in a normal room[31] |
| Post-Processing | ||
| Sanding & machining | Not documented | Wet sanding — dry sanding heats the surface by friction and smears it[29][22] |
| Gluing & solvent welding | Not documented | Cyanoacrylate for most joints; some grades partially dissolve and bond with acetone[22][32] |
| Vapour / chemical smoothing | Not documented | No practical vapour smoothing — only chloroform, hot benzene or THF, which are laboratory-only[22] |
| Support material pairing | Not documented | PolySupport and PolyDissolve S1 (Polymaker)[3] |
| Solvents & Solubility | ||
| Soluble in | Dissolved at 23 °C by formic acid, phenol, m-cresol, 96 % sulphuric acid or hexafluoroisopropanol — all laboratory reagents.[33][34] | Chloroform: 10 % w/v in 2–4 h at 23 °C, every grade and morphology; THF and DMF only at 65 °C. Laboratory reagents.[35] |
| Softened or crazed by | Mineral acids, oxidants, halogens and zinc chloride solutions attack the amide bond; ordinary solvents do not (BASF, PA6/66).[33] | Acetone, ethyl acetate and toluene plasticise it but dissolve <1 % even at 65 °C; submersion in acetone crazes and destroys parts.[35][36] |
| Solvent welding & smoothing agent | None — nylon's only solvents are formic acid, phenol and HFIP, all of which degrade the part they wet.[33] | Chloroform vapour smooths and welds PLA at the cost of tensile strength; acetone does not smooth it at all.[37][36] |
