Diameter tolerance± mm±0.03 (Bambu Lab)[15]Not documented
Printing Parameters
Nozzle temperature°C190–230 (Bambu Lab); 190–210 (Fiberlogy PLA Mineral)[2][1]Not documented
Bed temperature°C35–45 (Bambu Lab); 60 (Fiberlogy)[2][1]130–150 (3DXTech)[3]
Enclosure / chamber requirement1–5Open frame is fine[2][1]Actively heated chamber required[16][17]
Part cooling fanFan on; Fiberlogy specifies 75–100 %[2][1]Not documented
Bed surface & adhesion aidCool plate, high-temperature plate or textured PEI with glue (Bambu Lab); smooth PEI, textured PEI or glass (Fiberlogy)[2][1]Not documented
Warping tendency1–5None[2]Severe — heated chamber needed[16]
Bed-adhesion difficulty1–5Sticks to anything[18]Not documented
Overall printing difficulty1–5Beginner — prints on any machine out of the box[2][1]Expert / industrial hardware only[16][17]
Hardware Wear & Reliability
Nozzle hardness required1–4Brass fine indefinitely[19][2][1]Brass fine indefinitely for unfilled grades, but brass softens near these nozzle temperatures — hardened or plated hot ends are the norm[16]
Abrasiveness1–5Slightly abrasive — mineral filler pushes density from 1.24 to 1.31–1.38[1][2][20]Non-abrasive when unfilled[3]
Nozzle clog risk1–5Very low[19]Moderate — needs dry filament and a clean nozzle; 3DXTech lists no special nozzle concerns but a mandatory 120 °C pre-dry before every print[21]
Heat-creep / jam sensitivity1–5Moderate — good heatbreak cooling needed; PLA softens below 60 °C[22]Not documented
Hotend requirementNo special hot-end required[18]Not documented
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5Moderate — 0.40 % saturated at 25 °C / 55 % RH[2]Not documented
Equilibrium moisture content at ~50 % RH%0.40 saturated at 25 °C / 55 % RH (Bambu Lab)[2]0.37 in 24 h and 1.1 at saturation on extruded stock (ASTM D570)[23]
Drying temperature & time50 °C for 8 h in a forced-air dryer, or 60–70 °C for 12 h on an X1 heatbed; Fiberlogy specifies 50 °C for 6 h[2][1][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]No dry-versus-conditioned figures are published; 3DXTech mandates a 120 °C, 4 h pre-dry before every print because trapped water flashes to steam at these nozzle temperatures[21]
Storage requirementSealed with desiccant below 20 % RH; shelf life at ambient is long[20][18]Not documented
Mechanical Properties
Tensile strength (XY)MPa30 (printed XY, ISO 527, Bambu Lab); 35.1 on My Tech Fun bars for PolyTerra PLA[2][26]55 (printed XY, ISO 527, 3DXTech) and 55 (printed on side long edge, ASTM D638, Stratasys PPSF); 79 at yield on extruded stock[3][4][23]
Young's modulusMPa1960 (Bambu Lab, printed XY, ISO 527); Fiberlogy PLA Mineral quotes 3500 (ISO 527, specimen type not stated)[2][1]2100 (printed, ASTM D638, Stratasys PPSF) and 2310 (printed XY, ISO 527, 3DXTech); 2344 on extruded stock[3][4][23]
Elongation at break%14.8 (printed XY, ISO 527)[2]3 (printed, ISO 527 and ASTM D638) against 60 on extruded stock — printing costs PPSU almost all of its ductility[3][4][23]
Flexural strengthMPa53 (printed XY, ISO 178) — 30 % below PLA Basic at 76[2][20]110 (printed, ISO 178 and ASTM D790, 3DXTech and Stratasys PPSF agree); 91 on extruded stock[3][4][23]
Flexural modulusMPa2360 (printed XY, ISO 178)[2]2200 (printed, ASTM D790, Stratasys PPSF) and 2215 (printed XY, ISO 178, 3DXTech)[3][4]

Other impact dataIzod 6.1 kJ/m² on My Tech Fun printed bars for PolyTerra PLA[26]Izod notched 58.7 J/m and unnotched 165.5 J/m (printed, ASTM D256 Method A, Stratasys PPSF); 160 J/m notched on extruded stock[4][23]
Layer adhesion / Z tensileMPa22 (printed Z, ISO 527); flexural Z falls to 29 against 53 in XY; 12.9 on My Tech Fun layer-adhesion bars[2][26]Not documented
Brittleness1–5Brittle — snaps with little warning[2]Brittle — snaps with little warning[3]

Creep resistance / sustained load1–5Poor — 12 mm bar sagged to 18.7 mm over 5 days at 1.25 kg[26]Good. Printed PPSF holds 189 °C heat deflection at 1.8 MPa (ASTM D648) and extruded stock is rated 149 °C long-term service, but Ensinger does not claim the creep resistance it claims for PSU and PPS[4][23]
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[2]Rigid[3]
Z strength as % of XY%73 by tensile, 55 by flexural (printed, Bambu Lab)[2]Not documented
Thermal Properties
HDT at 0.45 MPa°C58 (Bambu Lab) and 48 (Fiberlogy PLA Mineral), ISO 75 at 0.45 MPa[2][1]190 (printed XY, ISO 75 at 0.45 MPa, 3DXTech)[3]

Melting point / Vicat°C163 peak melt (DSC); Vicat 63 °C[2]Not documented
Continuous service temperature°C54 — loaded bars begin to move at this temperature[26]149 long-term service on extruded PPSU stock, converted from 300 °F[23]
Annealing response50–60 °C for 6–12 h; some prints deform or warp, and a forced-air oven is required[2]Not documented
Thermal expansion (CTE)µm/m·KNot documented55.0 (printed PPSF, ASTM D696; source states 5.5e-5 mm/mm/°C) and 55.8 on extruded stock (ASTM D696, from 3.1e-5 in/in/°F)[4][23]
Flammability / UL 94Flammable; no UL 94 rating published by the major brands[20][28]UL 94 V-0 at 1.5 mm, rated on the base resin[3]
Environment & Chemical
UV resistance1–5Degrades within weeks outdoors[22][29]Not documented
Chemical resistanceGood against weak acids, oils and grease; poor against strong acids and alkalis; dissolved by chloroform, THF and hot benzene[28][22]Withstands repeated steam autoclaving, the usual reason to choose PPSU over PSU; Stratasys also lists PPSF as passing 24 h stress-crack exposure to antifreeze, petrol, motor oil, power-steering, transmission and washer fluid at 23 °C and 100 °C[3][4]
Water / humidity resistance in service1–5Good — insoluble in water[20]Not documented
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
Electrical & ESD propertiesNot documentedVolume resistivity 5e13 to 1.5e14 ohm-cm and dielectric strength 80-290 V/mil on printed PPSF (ASTM D257, D149)[4]
Health & Safety
Fume toxicity1–5Low hazard — minimal VOC and particle emission[31]Moderate — measurable VOCs and UFPs, ventilation advised. None of these polymers was in the chamber study, and all are processed far above the temperatures it covered[31]
Ventilation / filtration requirement1–5None needed in a normal room[31]Ventilated room or enclosure recommended[31]
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 pairingSupport for PLA (Bambu Lab)[2]Not documented
Dimensional accuracy & detailMatte surface hides layer lines; 55° overhangs and 30 mm bridges as for plain PLA[2]Not documented
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]Dichloromethane dissolves it at 23 °C at every stress level; acetone solvates and softens unstressed PPSU (Solvay ESCR).[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]MEK ruptures stressed parts and toluene crazes them above 13.8 MPa; glass-filled grades survive where unfilled craze.[34]
Solvent welding & smoothing agentChloroform vapour smooths and welds PLA at the cost of tensile strength; acetone does not smooth it at all.[36][35]Dichloromethane cements PPSU and NMP softens residual resin; both are laboratory reagents, not workshop stock.[34]
