| Identity & Market | ||
| Base polymer / chemistry | PLA with a blowing agent. Two distinct types: active-foaming grades that expand at the nozzle (Bambu Lab PLA Aero, colorFabb LW-PLA) and pre-foamed grades that do not (Polymaker PolyLite LW-PLA, PolyWood)[1][2][3][4] | Carbon-fibre reinforced PPS — Polymaker's Fiberon grade is nominally 10 wt%[5] |
| Densityg/cm³ | Filament 1.21 (Bambu Lab) and 1.24 (colorFabb); pre-foamed filament 0.8 (PolyWood, at 21.5 °C) and 0.9 (Polymaker LW-PLA); foamed prints reach 0.40[1][2][3][4] | 1.29 (Fiberon PPS-CF10) and 1.36 (Fiberon PPS-GF20), ISO 1183[5][6] |
| Typical priceUSD/kg | 1 kg-equivalent spools cluster near 45[7][2][8] | 1 kg-equivalent spools span 93–174; the middle of the market is about 140[8][9][10][11] |
| Price range across brandsUSD/kg | 37–50 across brands; Polymaker LW-PLA 37, Bambu Lab Aero 45, colorFabb 50, PolyWood 50[8][7][2] | 93-174 across brands and formats; Polymaker Fiberon PPS-GF20 93 at 3 kg, IEMAI 3D CF-PPS 131 at 750 g, LEHVOSS Luvocom 3F PPS CF 9938 164 at 2.3 kg, Bambu Lab PPS-CF 174 at 750 g[8][9][10][11] |
| Market availability1–5 | Available from several mainstream brands[7][8][2] | Available from several mainstream brands[8][9][10] |
| Spool sizes & diameters | 1.75 and 2.85 mm; 0.6, 0.75, 0.8 and 1 kg spools[8][2] | 1.75 mm; 0.5 kg spools[8] |
| Typical applications | RC aircraft, drone airframes and large props where mass matters more than strength[1][2] | Chemical and automotive parts needing PPS chemistry with structural stiffness[5] |
| Printing Parameters | ||
| Nozzle temperature°C | 210–260 (Bambu Lab, foaming); 195–260 (colorFabb, foaming); 190–210 (Polymaker, pre-foamed)[1][2][3] | Not documented |
| Bed temperature°C | 35–45 (Bambu Lab); 50–60 (colorFabb); 25–60 (Polymaker)[1][2][3] | Not documented |
| Enclosure / chamber requirement1–5 | Open frame is fine[3] | Enclosure required (passive) — Polymaker states its Fiberon PPS-CF10 needs no heated chamber, unlike the unfilled sulfones and PAEKs[5] |
| Part cooling fan | Fan on[1][3] | Not documented |
| Maximum volumetric flow (mm³/s; see test conditions)mm³/s | 3.2–8 at the 40–100 mm/s colorFabb specifies and the 50–100 mm/s Polymaker specifies, on a 0.4 mm nozzle at 0.2 mm layer[3][2][12] | Not documented |
| Overall printing difficulty1–5 | Intermediate — dry filament and a tuned profile; flow has to be cut to match the expansion[2] | Expert / industrial hardware only[5] |
| Extruder requirement | Bambu Lab PLA Aero is 0.4 mm nozzle only on the store and wiki, while its own TDS lists 0.4, 0.6 and 0.8[1][13] | Not documented |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Brass fine indefinitely[3][4] | Hardened steel required[5] |
| Abrasiveness1–5 | Non-abrasive[3][4] | Highly abrasive — standard CF composite[5] |
| Nozzle clog risk1–5 | High — jams from moisture, heat creep or particles; Bambu Lab warns the foamed extrudate swells and easily clogs the nozzle, and rules out 0.2 mm nozzles[13] | High — jams from moisture, heat creep or particles; Polymaker specifies hardened steel or ruby nozzles for carbon-filled PPS and Prusa lists composites as a higher clogging risk[14][15] |
| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | Moderate — 0.45 % saturated at 25 °C / 55 % RH (Bambu Lab); 0.40 % equilibrium (Polymaker)[1][3] | Low (0.1–0.3 %) — 0.225 % equilibrium for Fiberon PPS-CF10 and 0.11 % for PPS-GF20[5][6] |
| Equilibrium moisture content at ~50 % RH% | 0.45 saturated at 25 °C / 55 % RH (Bambu Lab); 0.40 equilibrium (Polymaker)[1][3] | 0.225 equilibrium (Fiberon PPS-CF10); 0.11 (PPS-GF20)[5][6] |
| Drying temperature & time | 55 °C for 6–8 h[1][3] | Not documented |
| Effect of moisture on strength | Polymaker rates PLA low-sensitivity and publishes no dry-versus-conditioned figures for this grade; absorbed water flashes to steam and shows as bubbling and poor layer adhesion[16] | No dry-versus-conditioned figures are published; equilibrium uptake is 0.225 % and Polymaker specifies a 100 °C, 10 h dry[5] |
| Mechanical Properties | ||
| Tensile strength (XY)MPa | 24 ± 2 (Bambu Lab) and 24.4 (Polymaker) printed XY, ISO 527; colorFabb falls from 43.1 unfoamed to 10.8 at 45 % flow[1][3][2] | 59.4 ± 1.3 (PPS-CF10) and 64.1 ± 2.1 (PPS-GF20) printed XY, ISO 527[5][6] |
| Young's modulusMPa | 1350 ± 250 (Bambu Lab) and 1689 (Polymaker) printed XY, ISO 527; colorFabb falls from 3334 unfoamed to 864 foamed[1][3][2] | 5446.7 ± 149.0 (PPS-CF10) and 4552.0 ± 54.6 (PPS-GF20) printed XY, ISO 527[5][6] |
| Elongation at break% | 2.6 ± 0.7 (Bambu Lab) and 8.8 (Polymaker) printed XY, ISO 527[1][3] | 1.4 ± 0.1 (PPS-CF10) and 2.0 ± 0.2 (PPS-GF20) printed XY, ISO 527 — the lowest elongation in the dataset[5][6] |
| Flexural strengthMPa | 45 ± 4 (Bambu Lab) and 50.2 (Polymaker) printed XY, ISO 178[1][3] | Not documented |
| Flexural modulusMPa | 1690 ± 120 (Bambu Lab) and 1959 (Polymaker) printed XY, ISO 178[1][3] | Not documented |
| Charpy impact, notchedkJ/m² | 8.2 ± 0.7 printed XY, ISO 179, notched (Bambu Lab); colorFabb 3.67 foamed[1][2] | 5.3 ± 0.2 printed XY for PPS-CF10 and 7.3 ± 0.2 for PPS-GF20, ISO 179 notched[5][6] |
| Other impact data | Charpy unnotched 28.8 printed XY (Bambu Lab); colorFabb 5.46 foamed[1][2] | Not documented |
| Layer adhesion / Z tensileMPa | 18 ± 3 printed Z, ISO 527 (Bambu Lab); flexural Z collapses to 17 against 45 in XY[1] | 32.0 ± 5.1 (PPS-CF10) and 22.9 ± 0.8 (PPS-GF20) printed Z, ISO 527[5][6] |
| Brittleness1–5 | Brittle — snaps with little warning; elongation at break 2.6 % in XY and 1.2 % in Z[1] | Very brittle — cracks or shatters easily; elongation at break 1.4 %[5] |
| Hardness (scale-specific)Shore A / Shore D / Rockwell | Not documented | Rockwell 105 (and R124) on extruded unfilled PPS stock (ASTM D785); no figure is published for a fibre-filled PPS filament[17] |
| Creep resistance / sustained load1–5 | Poor — no foamed-grade creep test; plain printed PLA sagged from 12 to 16.2–21.8 mm over 5 days at 1.25 kg, and the foam carries less solid[18][19][20] | Excellent — holds load for years. Ensinger lists high creep resistance for unfilled PPS stock and Spectrum states creep resistance is unchanged under continuous load at high temperature; the fibre raises heat deflection to 252 °C at 0.45 MPa[17][21][5] |
| Fatigue / repeated-flex resistance1–5 | Poor — no grade-specific S-N curve; plain printed PLA ran 38 000–49 000 cycles at 30 % of tensile strength and elongation at break falls to 2.6 % in XY and 1.2 % in Z[22][1] | Not documented |
| Elasticity / flexibility1–5 | Rigid[1] | Rigid[5] |
| Z strength as % of XY% | 75 by tensile, 38 by flexural (printed, Bambu Lab)[1] | 54 (PPS-CF10) and 36 (PPS-GF20), printed[5][6] |

| Melting point / Vicat°C | 150 peak melt (Polymaker, DSC); Vicat 60 °C[3] | 279.7 (PPS-CF10) and 279.6 (PPS-GF20) melting, DSC; Vicat 267.5 and 272.5 (ISO 306)[5][6] |
| Continuous service temperature°C | Not documented | 170 long-term service on extruded PPS stock, converted from 338 °F; no figure published for the carbon-filled grade[17] |
| Annealing response | Bambu Lab advises against annealing thin, low-infill Aero prints[1] | Not documented |
| Environment & Chemical | ||
| UV resistance1–5 | Degrades within weeks outdoors[23] | Not documented |
| Chemical resistance | Not documented | Outstanding — PPS resists essentially all solvents below 200 °C[14] |
| Electrical & ESD properties | Not documented | Surface resistivity above 10¹² ohm — insulating (ANSI/ESD S11.11)[5][6] |
| Health & Safety | ||
| Fume toxicity1–5 | Low hazard — minimal VOC and particle emission[24] | 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[24] |
| Ventilation / filtration requirement1–5 | None needed in a normal room[24] | Ventilated room or enclosure recommended[24] |
| Dust & fibre handling hazard | Not documented | Fibre is bound in the matrix; sanding dust should not be inhaled[5] |
| Post-Processing | ||
| Dimensional accuracy & detail | Foamed surfaces are rough and matte; dimensional accuracy depends on holding the foaming temperature steady[1][2] | Not documented |
| Solvents & Solubility | ||
| Soluble in | Chloroform dissolves the PLA matrix; the foamed wall wicks solvent right through instead of only skinning over.[25] | None — PPS does not dissolve in any known solvent below 200 °C.[26][27] |
| Softened or crazed by | Acetone, ethyl acetate and toluene plasticise the matrix but dissolve <1 % even at 65 °C; acetone submersion crazes parts.[25][28] | Nothing at 23 °C; Ensinger rates it only conditionally resistant to benzene, dichloromethane, toluene and pyridine.[27] |
| Solvent welding & smoothing agent | Chloroform vapour reaches only the resin skin; no workshop-safe smoothing agent exists for PLA of any kind.[29][28] | None — no solvent welds or smooths PPS.[26] |
