| Typical applications | Stiff tooling and fixtures that must survive above 100 °C[1] | Large or repetitive prints on printers that can sustain high flow[18][16] |
| Diameter tolerance± mm | Not documented | ±0.03 (Bambu Lab PLA Basic, rated to 258 mm/s)[19] |
| Printing Parameters | ||
| Nozzle temperature°C | Not documented | 210–230 for high-speed work; 190–210 at classic speeds[2][16] |
| Bed temperature°C | Not documented | 30–60 (Polymaker); 35–45 (Bambu Lab)[2][20] |
| Enclosure / chamber requirement1–5 | Enclosure recommended[21] | Open frame is fine[2] |
| Part cooling fan | Not documented | Fan on[2] |
| Bed surface & adhesion aid | Clean the plate and apply glue; Simplify3D also lists Kapton tape and ABS slurry[21][22] | Not documented |
| Maximum volumetric flow (mm³/s; see test conditions)mm³/s | Not documented | ≈24 at 300 mm/s with a 0.4 mm nozzle and 0.2 mm layer; 30 % more flow than regular PLA at the same temperature[2][16][18][23] |
| Warping tendency1–5 | Moderate — needs adhesion aid or draught shield; the fibre reduces warping against unfilled ABS[21] | None[2] |
| Bed-adhesion difficulty1–5 | Needs a specific surface plus adhesive[21] | Sticks to anything[24] |
| Stringing / oozing tendency1–5 | Slight — Polymaker advises 1–2 mm retraction at 20–30 mm/s[25] | Not documented |
| Overall printing difficulty1–5 | Intermediate — dry filament and a tuned profile; hardened nozzle mandatory[21] | Easy — minor profile tuning; needs a printer that can actually reach the flow rate[16][2] |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Hardened steel required[21] | Brass fine indefinitely[26] |
| Abrasiveness1–5 | Highly abrasive — standard CF composite[21] | Non-abrasive[27][26] |
| Nozzle clog risk1–5 | Moderate — needs dry filament and a clean nozzle; 3DXTech specifies a hardened nozzle of 0.4 mm minimum and 0.25 mm layers or higher, and Prusa lists composites as a higher clogging risk[28][29][30] | Very low[26] |
| Heat-creep / jam sensitivity1–5 | Slightly sensitive[22] | Moderate — good heatbreak cooling needed; PLA softens below 60 °C[31] |
| Hotend requirement | No special hot-end required[22] | No special hot-end required[24] |
| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | Moderate — the ABS matrix takes up 0.51–0.65 % saturated at 25 °C / 55 % RH and 3DXTech specifies a 80 °C, 4 h pre-dry[32][33][28] | Moderate — 0.40 % equilibrium at 23 °C / 70 % RH[2] |
| Equilibrium moisture content at ~50 % RH% | Not documented | 0.40 equilibrium at 23 °C / 70 % RH (Polymaker PolySonic)[2] |
| Drying temperature & time | Not documented | 55 °C for 6 h; 50 °C for 8 h (Bambu Lab)[2][20] |
| Symptoms when wet | Bubbling and popping at the nozzle, stringing and a rough surface[34] | Bubbling and popping at the nozzle, stringing, rough surface and weak layers[34] |
| Effect of moisture on strength | Polymaker rates ABS moderate-sensitivity and publishes no dry-versus-conditioned figures; absorbed water flashes to steam in the hotend and shows as bubbling and poor layer adhesion[34] | Polymaker rates PLA low-sensitivity — the loss shows as poor layer adhesion and brittle layers rather than a published strength figure[34] |
| Storage requirement | Sealed with desiccant; Polymaker rates ABS moderate-sensitivity[34] | Sealed with desiccant below 20 % RH; shelf life at ambient is long[20][24] |
| Mechanical Properties | ||
| Tensile strength (XY)MPa | 46 at break (printed XY, ISO 527)[1] | 43.9 at 300 mm/s and 46.0 at 46.7 mm/s (printed XY, ISO 527); 58.6 on My Tech Fun bars for Creality Hyper PLA[2][35] |
| Young's modulusMPa | 5210 (printed XY, ISO 527) — more than double unfilled ABS[1] | 2650 at 300 mm/s, 2878 at classic speed (printed XY, ISO 527)[2] |
| Elongation at break% | 2 at break (printed XY, ISO 527)[1] | 15.1 at 300 mm/s, 21.5 at classic speed (printed XY, ISO 527)[2] |

| Other impact data | Not documented | Printing at 300 mm/s instead of 46.7 mm/s costs 4.6 % tensile strength and 18 % notched Charpy[2] |
| Layer adhesion / Z tensileMPa | Not documented | 32.4 at 300 mm/s, 37.3 at classic speed (printed Z, ISO 527); 35.3 for Creality Hyper PLA vs 23.0 for average PLA on identical bars[2][35] |
| Brittleness1–5 | Brittle — snaps with little warning; elongation at break 2 %[1] | Moderate[2] |
| Hardness (scale-specific)Shore A / Shore D / Rockwell | Not documented | 78.7 Shore D measured on printed bars for Sunlu PLA Meta (My Tech Fun), against 75.3 for the same maker's plain PLA[36] |
| Creep resistance / sustained load1–5 | Good — no creep test found; chopped carbon fibre restrains matrix flow and modulus rises to 5210 MPa against 2200–2330 for unfilled ABS[1][32][33] | Poor — 12 mm bar sagged to 17.7 mm over 6 days at 1.25 kg[35] |
| Fatigue / repeated-flex resistance1–5 | Below average — no S-N curve found; elongation at break falls to 2 % against 10.5 % for unfilled ABS[1][32] | Poor — no grade-specific S-N curve; plain printed PLA ran 38 000–49 000 cycles at 30 % of tensile strength (R = 0.2)[37][31] |
| Elasticity / flexibility1–5 | Rigid[1] | Rigid[2] |
| Z strength as % of XY% | Not documented | 74 at 300 mm/s, 81 at classic speed (printed)[2] |
| Thermal Properties | ||
| HDT at 0.45 MPa°C | Not documented | 53 (ISO 75, 0.45 MPa)[2] |
| HDT at 1.8 MPa°C | Not documented | 52 (ISO 75, 1.8 MPa)[2] |

| Melting point / Vicat°C | Not documented | 164 peak melt (DSC); crystallisation 96 °C, Vicat 61 °C[2] |
| Continuous service temperature°C | Not documented | 53 — loaded bars begin to move at this temperature[35] |

| Flammability / UL 94 | Not documented | Flammable; no UL 94 rating published by the major brands[20][3] |
| Environment & Chemical | ||
| UV resistance1–5 | Not documented | Degrades within weeks outdoors[31][40] |
| Chemical resistance | Good against weak acids, weak alkalis, oils and grease; dissolved by acetone[41] | Good against weak acids, oils and grease; poor against strong acids and alkalis[2] |
| Water / humidity resistance in service1–5 | Not documented | Good — insoluble in water[20] |
| Food contact | Not food safe — Polymaker cites potential chemical leaching[25] | Base resin is food-contact grade, but printed layer grooves harbour bacteria; Prusa advises against food use[31] |
| Biodegradability / compostability | Not biodegradable[25] | Industrially compostable only — needs sustained 55 °C; not home compostable[42][31] |
| Recyclability | Mechanically recyclable but not accepted in household plastic collection[25] | Mechanically recyclable; not accepted in household plastic collection[42] |
| Electrical & ESD properties | Surface resistance above 10⁹ ohm/sq — not static-dissipative (ASTM D257)[1] | Not documented |
| Health & Safety | ||
| Fume toxicity1–5 | High — hazardous VOC such as styrene; enclosure and filtration needed[43][21] | Low hazard — minimal VOC and particle emission[43] |
| VOC emission rateµg/min | 12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[43] | Not documented |
| Ultrafine-particle emission rateparticles/min | 2 × 10¹⁰ to 9 × 10¹⁰ median across all ABS printers, two orders of magnitude above PLA's ≈1 × 10⁸[43] | Not documented |
| Hazardous species emitted | Styrene dominates. Bambu Lab states ABS and ASA release harmful gases such as styrene at printing temperature, which can be toxic and cause dizziness or nausea[43][21] | Not documented |
| Ventilation / filtration requirement1–5 | Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[43][21] | None needed in a normal room[43] |
| Dust & fibre handling hazard | Carbon fibre is bound in the matrix; sanding dust should not be inhaled[1] | Not documented |
| Post-Processing | ||
| Sanding & machining | Sands well and takes filler before painting[25] | Wet sanding — dry sanding heats the surface by friction and smears it[40][31] |
| Painting & finishing | Paints readily after light abrasion[25] | Not documented |
| Gluing & solvent welding | Not documented | Cyanoacrylate for most joints; some grades partially dissolve and bond with acetone[31][44] |
| Vapour / chemical smoothing | Acetone smoothing is blunted by the fibre — only the resin fraction dissolves[41] | No practical vapour smoothing — only chloroform, hot benzene or THF, which are laboratory-only[31] |
| Support material pairing | HIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[45][21] | PolySupport and PolyDissolve S1 (Polymaker)[2] |
| Solvents & Solubility | ||
| Soluble in | Acetone dissolves the resin and leaves the fibre as sludge; MEK, THF, ethyl acetate and chlorinated solvents do the same.[46][41] | Chloroform: 10 % w/v in 2–4 h at 23 °C, every grade and morphology; THF and DMF only at 65 °C. Laboratory reagents.[47] |
| Softened or crazed by | Petrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[46][48] | Acetone, ethyl acetate and toluene plasticise it but dissolve <1 % even at 65 °C; submersion in acetone crazes and destroys parts.[47][49] |
| Solvent welding & smoothing agent | Acetone vapour reaches only the resin fraction, so the fibre is left standing proud of the smoothed surface.[49][41] | Chloroform vapour smooths and welds PLA at the cost of tensile strength; acetone does not smooth it at all.[50][49] |
