| Recommended chamber temperature°C | 45–60 (Bambu Lab)[1] | 60-80 actively heated (Spectrum PPS AM230)[6] |
| Part cooling fan | Fan on (Bambu Lab)[1] | Not documented |
| Bed surface & adhesion aid | PEI sheet, BuildTak or an adhesion aid such as Magigoo (Polymaker); Simplify3D also lists Kapton tape and ASA slurry[17][18] | Adhesive required — Spectrum specifies Magigoo Pro HT[6] |
| Maximum volumetric flow (mm³/s; see test conditions)mm³/s | 20 at Bambu Lab's 250 mm/s cap on a 0.4 mm nozzle at 0.2 mm layer[1][19] | Not documented |
| Warping tendency1–5 | Moderate — needs adhesion aid or draught shield; the fibre reduces warping against unfilled ASA[14] | Not documented |
| Bed-adhesion difficulty1–5 | Needs a specific surface plus adhesive[17] | Not documented |
| Stringing / oozing tendency1–5 | Slight — Polymaker advises 1–2 mm retraction at 20–30 mm/s[17] | Not documented |
| Overall printing difficulty1–5 | Intermediate — dry filament and a tuned profile; hardened nozzle mandatory[14] | Expert / industrial hardware only[15][16] |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Hardened steel required[14] | Brass fine indefinitely for unfilled grades, but brass softens near these nozzle temperatures — hardened or plated hot ends are the norm[15] |
| Abrasiveness1–5 | Highly abrasive — standard CF composite[14] | Non-abrasive when unfilled[4] |
| Nozzle clog risk1–5 | Moderate — needs dry filament and a clean nozzle; Prusa lists higher risk of nozzle clogging for fibre-filled composites and Simplify3D a higher tendency to clog[20][21] | Moderate — needs dry filament and a clean nozzle; 3DXTech lists no special nozzle concerns but a mandatory 110 °C pre-dry before every print[22] |
| Heat-creep / jam sensitivity1–5 | Slightly sensitive[18] | Not documented |
| Hotend requirement | No special hotend required[18] | Not documented |
| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | Moderate — 0.33 % saturated at 25 °C / 55 % RH (Bambu Lab)[1] | Negligible (<0.1 % EMC) — Polymaker states minimal water absorption at 0.05 %[5] |
| Equilibrium moisture content at ~50 % RH% | 0.33 saturated at 25 °C / 55 % RH (Bambu Lab)[1] | 0.01 in 24 h on extruded stock (ASTM D570) — effectively non-absorbing[23] |
| Drying temperature & time | 80 °C for 8 h (Bambu Lab)[1] | At least 3 h at 90 °C in hot dry air if the filament has taken up moisture (Spectrum)[6] |
| Symptoms when wet | Bubbling and popping at the nozzle, stringing and a rough surface[24] | Not documented |
| Effect of moisture on strength | No dry-versus-conditioned figures are published; Polymaker groups the styrenics as moderate-sensitivity and absorbed water shows as bubbling and poor layer adhesion[24] | Little to measure — equilibrium uptake is 0.05 %; 3DXTech still specifies a 110 °C, 4 h pre-dry before printing[5][22] |
| Storage requirement | Sealed with desiccant; Polymaker rates the styrenics moderate-sensitivity[24] | Not documented |
| Mechanical Properties | ||
| Tensile strength (XY)MPa | 34 ± 3 printed XY, ISO 527 (Bambu Lab); 3DXTech quotes 48 at break and Formfutura 79 at 23 °C[1][2][3] | 50 at break (printed XY, ISO 527, 3DXTech); 65 at break injection-moulded (ISO 527, Spectrum); 94 at yield on extruded stock (ASTM D638)[4][6][23] |
| Young's modulusMPa | 4200 ± 270 printed XY, ISO 527 (Bambu Lab); 3DXTech quotes 5355 and Formfutura 7580[1][2][3] | 2650 (printed XY, ISO 527, 3DXTech); 3650 injection-moulded (ISO 527, Spectrum); 5769 on extruded stock (ASTM D638)[4][6][23] |
| Elongation at break% | 9.6 ± 1.4 printed XY, ISO 527 (Bambu Lab); 3DXTech quotes 3 at break and Formfutura 1.8[1][2][3] | 18 at break (printed XY, ISO 527, 3DXTech) against 2.0 injection-moulded (Spectrum) and 2.5 on extruded stock — the suppliers disagree by nearly an order of magnitude[4][6][23] |
| Flexural strengthMPa | 72 ± 5 printed XY, ISO 178 (Bambu Lab); 3DXTech quotes 78[1][2] | 52 (printed XY, ISO 178, 3DXTech); 141 on extruded stock (ASTM D790)[4][23] |
| Flexural modulusMPa | 3740 ± 130 printed XY, ISO 178 (Bambu Lab); 3DXTech quotes 5210[1][2] | 2540 (printed XY, ISO 178)[4] |

| Hardness (scale-specific)Shore A / Shore D / Rockwell | Not documented | Rockwell 105 (and R124) on extruded PPS stock (ASTM D785)[23] |
| Creep resistance / sustained load1–5 | Good — no creep test found; chopped carbon fibre lifts modulus to 4200 MPa against 2379–2450 for unfilled ASA[1][26] | Excellent — holds load for years. Ensinger lists high creep resistance as a headline property of extruded PPS stock, and Spectrum states that rigidity, strength and creep resistance are unchanged under continuous load at high temperature[23][6] |
| Fatigue / repeated-flex resistance1–5 | Below average — no CF-grade S-N curve; notched Charpy falls to 6.2 kJ/m² against 19.6 for unfilled Bambu Lab ASA[1][25] | Not documented |
| Elasticity / flexibility1–5 | Rigid[1] | Rigid[4] |

| Melting point / Vicat°C | Not documented | 283 melting (ISO 11357, 3DXTech) and 280 on extruded stock; Vicat softening 236 at 50 N injection-moulded (ISO 306, Spectrum)[4][6][23] |
| Continuous service temperature°C | 93 — Prusa publishes this as the temperature resistance of Prusament ASA[27] | 170 long-term service on extruded PPS stock, converted from 338 °F[23] |
| Thermal expansion (CTE)µm/m·K | Not documented | 59.4 (extruded PPS stock, 22-60 °C, ASTM D696; source states 3.3e-5 in/in/°F)[23] |

| Food contact | Not food safe[17] | Not documented |
| Biodegradability / compostability | Not biodegradable[17] | Not documented |
| Recyclability | Not accepted in household plastic collection[17] | Not documented |
| Electrical & ESD properties | Surface resistance above 10⁹ ohm/sq — not static-dissipative (3DXTech, ASTM D257)[2] | Not documented |
| Health & Safety | ||
| Fume toxicity1–5 | High — hazardous VOC such as styrene; enclosure and filtration needed[29][14] | 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[29] |
| Hazardous species emitted | Styrene. Bambu Lab states ABS and ASA release harmful gases such as styrene at printing temperature, which can be toxic and cause dizziness or nausea. Azimi et al. measured styrene from every styrenic filament tested but did not test ASA itself[14][29] | Not documented |
| Ventilation / filtration requirement1–5 | Enclosure with carbon and HEPA filtration[29][14] | Ventilated room or enclosure recommended[29] |
| Dust & fibre handling hazard | Carbon fibre is bound in the matrix; sanding dust should not be inhaled[2] | Not documented |
| Post-Processing | ||
| Sanding & machining | Sands well and takes filler before painting[17] | Not documented |
| Painting & finishing | Paints readily; ASA holds colour outdoors so many parts are left unpainted[17] | Not documented |
| Gluing & solvent welding | Solvent-welds with acetone[26] | Not documented |
| Vapour / chemical smoothing | Acetone vapour smoothing works[26] | Not documented |
| Support material pairing | HIPS breaks away or dissolves in d-limonene; Bambu Lab sells a Support for ABS that also serves ASA[14] | Not documented |
| Dimensional accuracy & detail | Matte fibre-filled finish hides layer lines[1] | Not documented |
| Solvents & Solubility | ||
| Soluble in | Acetone dissolves the resin and leaves the fibre; MEK, THF, ethyl acetate and chlorinated solvents attack the styrenic backbone.[30][26] | None — PPS does not dissolve in any known solvent below 200 °C.[31][30] |
| Softened or crazed by | Limonene attacks some grades — Prusa reports Prusament ASA Orange flaking apart as layer adhesion fails.[32] | Nothing at 23 °C; Ensinger rates it only conditionally resistant to benzene, dichloromethane, toluene and pyridine.[30] |
| Solvent welding & smoothing agent | Acetone vapour reaches only the resin fraction, so the fibre is left standing proud of the smoothed surface.[33][26] | None — no solvent welds or smooths PPS.[31] |
