| Typical applications | Display models and visible parts where a matte, non-reflective finish matters[2] | Lightweight chemical-resistant parts, automotive clips and ducting that must survive above 150 °C[15] |
| Diameter tolerance± mm | ±0.03 (Bambu Lab)[16] | ±0.04 (Prusament)[3] |
| Printing Parameters | ||
| Nozzle temperature°C | 190–230 (Bambu Lab); 190–210 (Fiberlogy PLA Mineral)[2][1] | 270 ± 10 (Prusament)[3] |
| Bed temperature°C | 35–45 (Bambu Lab); 60 (Fiberlogy)[2][1] | 85 ± 10 (Prusament)[3] |
| Enclosure / chamber requirement1–5 | Open frame is fine[2][1] | Enclosure recommended — Simplify3D lists an enclosure as a hardware requirement and Polymaker advises one below 70 °C ambient to stop warping and cracking[17][18] |
| Part cooling fan | Fan on; Fiberlogy specifies 75–100 %[2][1] | Off — Prusa runs 0 % except 100 % on bridges[3] |
| Bed surface & adhesion aid | Cool plate, high-temperature plate or textured PEI with glue (Bambu Lab); smooth PEI, textured PEI or glass (Fiberlogy)[2][1] | Not documented |
| Maximum volumetric flow (mm³/s; see test conditions)mm³/s | Not documented | 3.2 at Prusa's 40 mm/s cap on a 0.4 mm nozzle at 0.2 mm layer[3][19] |
| Warping tendency1–5 | None[2] | High — enclosure needed for reliable large parts; Prusa recommends a brim[3] |
| Bed-adhesion difficulty1–5 | Sticks to anything[20] | Very difficult — special plates or slurry required[3] |
| Overall printing difficulty1–5 | Beginner — prints on any machine out of the box[2][1] | Advanced — enclosure, hardware upgrades, tuning; hardened nozzle mandatory[3] |
| Extruder requirement | Not documented | Prusa states a hardened nozzle is necessary and recommends a brim[3] |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Brass fine indefinitely[21][2][1] | Hardened steel required — Prusa states plainly that a hardened nozzle is necessary[3] |
| Abrasiveness1–5 | Slightly abrasive — mineral filler pushes density from 1.24 to 1.31–1.38[1][2][22] | Highly abrasive — standard CF composite[3] |
| Nozzle clog risk1–5 | Very low[21] | Moderate — needs dry filament and a clean nozzle; 3DXTech specifies a hardened 0.4 mm minimum nozzle and 0.25 mm layers or higher, and Prusa lists composites as a higher clogging risk[4][23] |
| Heat-creep / jam sensitivity1–5 | Moderate — good heatbreak cooling needed; PLA softens below 60 °C[24] | Not documented |
| Hotend requirement | No special hot-end required[20] | Not documented |
| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | Moderate — 0.40 % saturated at 25 °C / 55 % RH[2] | Negligible (<0.1 % EMC) — Prusa measures 0.03 % in 24 h and 0.04 % in 7 days on its PP composite, the lowest figures it publishes for any filament[3] |
| Equilibrium moisture content at ~50 % RH% | 0.40 saturated at 25 °C / 55 % RH (Bambu Lab)[2] | 0.03 after 24 h and 0.04 after 7 days at 24 °C / 22 % RH (Prusa Polymers)[3] |
| Drying temperature & time | 50 °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][25] | Not documented |
| Symptoms when wet | Bubbling and popping at the nozzle, stringing, rough surface and weak layers[26] | Not documented |
| Effect of moisture on strength | Polymaker rates PLA low-sensitivity — the loss shows as poor layer adhesion and brittle layers rather than a published strength figure[26] | Not applicable in practice at 0.04 % equilibrium uptake[3] |
| Storage requirement | Sealed with desiccant below 20 % RH; shelf life at ambient is long[22][20] | No special storage needed[3] |
| Mechanical Properties | ||
| Tensile strength (XY)MPa | 30 (printed XY, ISO 527, Bambu Lab); 35.1 on My Tech Fun bars for PolyTerra PLA[2][27] | 21 ± 0.4 filament tensile yield (Prusament, ISO 527)[3] |

| Elongation at break% | 14.8 (printed XY, ISO 527)[2] | Not documented |
| Flexural strengthMPa | 53 (printed XY, ISO 178) — 30 % below PLA Basic at 76[2][22] | Not documented |
| Flexural modulusMPa | 2360 (printed XY, ISO 178)[2] | Not documented |
| Charpy impact, notchedkJ/m² | 6.3 (printed XY, ISO 179, notched); unnotched 19.2[2] | 14.5 ± 0.3 printed horizontal and 10.5 ± 0.8 printed vertical XZ (ISO 179-1, notched)[3] |
| Other impact data | Izod 6.1 kJ/m² on My Tech Fun printed bars for PolyTerra PLA[27] | Not documented |
| Layer adhesion / Z tensileMPa | 22 (printed Z, ISO 527); flexural Z falls to 29 against 53 in XY; 12.9 on My Tech Fun layer-adhesion bars[2][27] | Not documented |
| Brittleness1–5 | Brittle — snaps with little warning[2] | Tough — absorbs impact, yields before breaking[3] |
| Hardness (scale-specific)Shore A / Shore D / Rockwell | Not documented | Rockwell R102 (and M95) on extruded unfilled PP stock (ASTM D785); no figure is published for a carbon-fibre PP filament[28] |
| Creep resistance / sustained load1–5 | Poor — 12 mm bar sagged to 18.7 mm over 5 days at 1.25 kg[27] | Not documented |
| 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 (R = 0.2)[29][24] | Good[30] |
| Elasticity / flexibility1–5 | Rigid[2] | Slightly flexible in thin sections[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°C | 58 (Bambu Lab) and 48 (Fiberlogy PLA Mineral), ISO 75 at 0.45 MPa[2][1] | 158 (ISO 75, 0.45 MPa) — far above unfilled PP and above most engineering filaments[3] |
| HDT at 1.8 MPa°C | 52 (ISO 75, 1.8 MPa)[2] | 115 (ISO 75, 1.8 MPa)[3] |
| Glass transition (Tg)°C | 61 (DSC)[2] | Not documented |
| Melting point / Vicat°C | 163 peak melt (DSC); Vicat 63 °C[2] | Not documented |
| Continuous service temperature°C | 54 — loaded bars begin to move at this temperature[27] | Not documented |
| Annealing response | 50–60 °C for 6–12 h; some prints deform or warp, and a forced-air oven is required[2] | Not documented |
| Flammability / UL 94 | Flammable; no UL 94 rating published by the major brands[22][31] | Not documented |
| Environment & Chemical | ||
| UV resistance1–5 | Degrades within weeks outdoors[24][32] | Not documented |
| Chemical resistance | Good against weak acids, oils and grease; poor against strong acids and alkalis; dissolved by chloroform, THF and hot benzene[31][24] | Excellent against acids, alkalis and most solvents[18] |
| Water / humidity resistance in service1–5 | Good — insoluble in water[22] | Excellent — essentially unaffected[3] |
| Food contact | Base resin is food-contact grade, but printed layer grooves harbour bacteria; Prusa advises against food use[24] | Not documented |
| Biodegradability / compostability | Industrially compostable only — needs sustained 55 °C; not home compostable[33][24] | Not documented |
| Recyclability | Mechanically recyclable; not accepted in household plastic collection[33] | Not documented |
| Health & Safety | ||
| Fume toxicity1–5 | Low hazard — minimal VOC and particle emission[34] | Low hazard — minimal VOC and particle emission. Inferred: no polyolefin was among the nine filaments in the Azimi chamber study, so this is a family-level judgement rather than a measurement[34] |
| Ventilation / filtration requirement1–5 | None needed in a normal room[34] | Open a window / occasional ventilation. Inferred — no polyolefin was measured in the chamber study[34] |
| Dust & fibre handling hazard | Not documented | Carbon fibre is bound in the matrix; sanding dust should not be inhaled[3] |
| Post-Processing | ||
| Sanding & machining | Wet sanding — dry sanding heats the surface by friction and smears it[32][24] | Not documented |
| Gluing & solvent welding | Cyanoacrylate for most joints; some grades partially dissolve and bond with acetone[24][35] | Not documented |
| Vapour / chemical smoothing | No practical vapour smoothing — only chloroform, hot benzene or THF, which are laboratory-only[24] | Not documented |
| Support material pairing | Support for PLA (Bambu Lab)[2] | Not documented |
| Dimensional accuracy & detail | Matte surface hides layer lines; 55° overhangs and 30 mm bridges as for plain PLA[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.[36] | None at room temperature; chloroform dissolves the matrix at 60 °C and xylene at about 118 °C, leaving the fibre.[37][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.[36][39] | Xylene, decalin, CCl4 and chlorobenzene are heavily absorbed at 20 °C; oleum, chlorosulphonic acid and bromine destroy it.[37] |
| 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 — nothing softens PP at room temperature, so joints have to be welded thermally rather than chemically.[37] |
