| Stringing / oozing tendency1–5 | Slight — 1–3 mm retraction handles it[1][16] | Not documented |
| Overall printing difficulty1–5 | Easy — minor profile tuning; Tough+ wants a hotter nozzle than plain PLA[1][2] | Easy — minor profile tuning[3] |
| Extruder requirement | Not documented | A second extruder or a tool changer[3] |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Brass fine indefinitely[17] | Brass fine indefinitely[3] |
| Abrasiveness1–5 | Non-abrasive[18][17] | Non-abrasive[3] |
| Nozzle clog risk1–5 | Very low[17] | 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 sensitivity1–5 | Moderate — good heatbreak cooling needed; softens below 60 °C like plain PLA[19] | Not documented |
| Hotend requirement | No special hot-end required[16] | Not documented |
| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | Low — 0.27 % saturated at 25 °C / 55 % RH[2] | Moderate — 0.64 % equilibrium water absorption (PolySupport for PLA)[3] |
| Equilibrium moisture content at ~50 % RH% | 0.27 saturated at 25 °C / 55 % RH (Bambu Lab Tough+)[2] | 0.64 equilibrium water absorption (Polymaker PolySupport for PLA)[3] |
| Drying temperature & time | 55 °C for 6–8 h; 65–75 °C for 12 h on a Bambu Lab X1 heatbed[1][2] | Not documented |
| Symptoms when wet | Bubbling and popping at the nozzle, stringing, rough surface and weak layers[20] | Not documented |
| Effect of moisture on strength | Polymaker rates PLA low-sensitivity and publishes no dry-versus-conditioned figures for the modified grades; the loss shows as poor layer adhesion rather than a strength number[20] | Not a structural material; no dry-versus-conditioned data is published[20] |
| Storage requirement | Sealed with desiccant below 20 % RH; shelf life at ambient is long[2][16] | Not documented |
| Mechanical Properties | ||
| Tensile strength (XY)MPa | 35–43 (printed XY, ISO 527); 53 on My Tech Fun 4×4 mm bars for Bambu Lab Tough[1][2][21][22] | Not documented |
| Young's modulusMPa | 1860–2150 (printed XY, ISO 527) — below plain PLA at 2300–3427[1][2][23][24] | Not documented |
| Elongation at break% | 5.1–5.7 (printed XY, ISO 527)[1][2] | Not documented |

| Layer adhesion / Z tensileMPa | 20.9–32.4 printed Z (ISO 527); 33.0 on My Tech Fun layer-adhesion bars vs 27.6 for PLA Basic[1][2][22] | Not documented |
| Brittleness1–5 | Tough — absorbs impact, yields before breaking[1][2][21] | Not documented |
| Hardness (scale-specific)Shore A / Shore D / Rockwell | 78.8 Shore D measured on printed bars (My Tech Fun), against 75.3 for the same maker's plain PLA[26] | Not documented |
| Creep resistance / sustained load1–5 | Poor — 12 mm bar sagged to 20.2 mm over 5 days at 1.25 kg, the same as plain PLA[22][27] | Not documented |
| Fatigue / repeated-flex resistance1–5 | Below average — impact modifiers raise absorbed energy 5–9×; plain PLA ran 38 000–49 000 cycles at 30 % of tensile strength[28][2][21] | Not documented |
| Elasticity / flexibility1–5 | Rigid[1] | Not documented |
| Z strength as % of XY% | 60 (Bambu Lab Tough+) to 78 (PolyMax PLA), printed[1][2] | Not documented |
| Thermal Properties | ||

| HDT at 1.8 MPa°C | 52 (PolyMax) to 58 (Tough+), ISO 75 at 1.8 MPa[1][2] | 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)°C | 61 (DSC)[1][2] | Not documented |
| Melting point / Vicat°C | 149–151 peak melt (DSC); Vicat 62 (ISO 306)[1][2] | Vicat 171 (PolySupport for PA12, ISO 306)[4] |
| Continuous service temperature°C | 48–57 — loaded bars begin to move at this temperature: 48 for Polymaker PLA Pro, 50 for Sunlu PLA+, 52 for Bambu Lab Tough, 57 for PolyTerra PLA+[22][29][26][27] | Not documented |
| Thermal expansion (CTE)µm/m·K | 96–99 for plain printed PLA (fibre Bragg grating, 25–50 °C); no grade-specific measurement published[30] | Not documented |
| Flammability / UL 94 | Flammable; no UL 94 rating published by the major brands[2][1] | Not documented |
| Environment & Chemical | ||
| UV resistance1–5 | Degrades within weeks outdoors[19][31] | Not documented |
| Chemical resistance | Good against weak acids, oils and grease; poor against strong acids and alkalis[1][2] | Not documented |
| Food contact | Base resin is food-contact grade, but printed layer grooves harbour bacteria; Prusa advises against food use[19] | Not documented |
| Biodegradability / compostability | Industrially compostable only — needs sustained 55 °C; not home compostable[32][19] | Not documented |
| Recyclability | Mechanically recyclable; not accepted in household plastic collection[32] | Not documented |

| Ventilation / filtration requirement1–5 | None needed in a normal room[35] | Open a window / occasional ventilation[35] |
| Post-Processing | ||
| Sanding & machining | Wet sanding — dry sanding heats the surface by friction and smears it[31][19] | Not documented |
| Gluing & solvent welding | Cyanoacrylate for most joints; some grades partially dissolve and bond with acetone[19][36] | Not documented |
| Vapour / chemical smoothing | No practical vapour smoothing — only chloroform, hot benzene or THF, which are laboratory-only[19] | Not documented |
| Support material pairing | PolySupport and PolyDissolve S1 (Polymaker); Support for PLA (Bambu Lab)[1][2] | 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] |
| Dimensional accuracy & detail | 55° overhangs and 30 mm bridges (Bambu Lab Tough+)[2] | Not documented |
| Solvents & Solubility | ||
| Soluble in | Chloroform: 10 % w/v in 2–4 h at 23 °C, every grade and morphology; THF and DMF only at 65 °C. Laboratory reagents.[37] | None — break-away support is removed mechanically; 3DXTech lists no water or solvent route for it.[38] |
| Softened or crazed by | Acetone, ethyl acetate and toluene plasticise it but dissolve <1 % even at 65 °C; submersion in acetone crazes and destroys parts.[37][39] | Not documented |
| Solvent welding & smoothing agent | Chloroform vapour smooths and welds PLA at the cost of tensile strength; acetone does not smooth it at all.[40][39] | None — there is no solvent to weld or smooth with.[38] |
