| Typical applications | Electronics handling fixtures, trays and jigs used around static-sensitive parts[1] | Decorative prints where surface gloss matters more than strength[2] |
| Diameter tolerance± mm | Not documented | ±0.03 (Bambu Lab)[17] |
| Printing Parameters | ||
| Nozzle temperature°C | Not documented | 210–240 — 20 °C above the plain PLA window[2] |
| Bed temperature°C | Not documented | 35–45[2] |
| Enclosure / chamber requirement1–5 | Enclosure recommended[18] | Open frame is fine[2][19] |
| 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[18][20] | Cool Plate SuperTack, smooth PEI or textured PEI[2] |
| Warping tendency1–5 | High — enclosure needed for reliable large parts[18] | None[2] |
| Bed-adhesion difficulty1–5 | Needs a specific surface plus adhesive[18] | Sticks to anything[21] |
| Stringing / oozing tendency1–5 | Slight — Polymaker advises 1–2 mm retraction at 20–30 mm/s[22] | Not documented |
| Overall printing difficulty1–5 | Intermediate — dry filament and a tuned profile[18] | Easy — minor profile tuning; hotter nozzle and slower cap of 250 mm/s[2] |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Hardened steel required[1] | Brass fine indefinitely[19] |
| Abrasiveness1–5 | Moderately abrasive — conductive carbon filler[1] | Non-abrasive[23][19] |
| Nozzle clog risk1–5 | Low — 3DXTech lists no special nozzle concerns and no minimum layer height for its ESD-ABS, only an 80 °C pre-dry[24] | Very low[19] |
| Heat-creep / jam sensitivity1–5 | Slightly sensitive[20] | Moderate — good heatbreak cooling needed; PLA softens below 60 °C[25] |
| Hotend requirement | No special hot-end required[20] | No special hot-end required[21] |
| 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[26][27][24] | Moderate — 0.40 % saturated at 25 °C / 55 % RH[2] |
| Equilibrium moisture content at ~50 % RH% | Not documented | 0.40 saturated at 25 °C / 55 % RH (Bambu Lab)[2] |
| Drying temperature & time | Not documented | 55 °C for 8 h in a forced-air dryer, or 65–75 °C for 12 h on an X1 heatbed[2][28] |
| Symptoms when wet | Bubbling and popping at the nozzle, stringing and a rough surface[29] | Bubbling and popping at the nozzle, stringing, rough surface and weak layers[29] |
| 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[29] | Polymaker rates PLA low-sensitivity — the loss shows as poor layer adhesion and brittle layers rather than a published strength figure[29] |
| Storage requirement | Sealed with desiccant; Polymaker rates ABS moderate-sensitivity[29] | Sealed with desiccant below 20 % RH; shelf life at ambient is long[30][21] |
| Mechanical Properties | ||
| Tensile strength (XY)MPa | 58 at break (printed XY, ISO 527) — the conductive filler raises strength above the unfilled grade's 42[1][31] | 33 (printed XY, ISO 527); eSun Silk broke 22 % below the 16-brand PLA mean on identical 4×4 mm bars[2][32] |
| Young's modulusMPa | 2130 (printed XY, ISO 527)[1] | 2130 (printed XY, ISO 527)[2] |

| Layer adhesion / Z tensileMPa | Not documented | 25 (printed Z, ISO 527), and flexural Z collapses to 30 against 75 in XY; eSun Silk broke at 12.3 kg where twelve of the 16 plain PLAs managed 44.6–61.5 kg[2][32][33] |
| Brittleness1–5 | Moderate[1] | Brittle — snaps with little warning[2] |
| Creep resistance / sustained load1–5 | Moderate — no creep test found; Tg of 105 °C keeps room-temperature service far below softening[1] | Poor — no silk-specific creep data published; plain PLA sagged from 12 to 18.7–20.3 mm over 5 days at 1.25 kg[34][35] |
| Fatigue / repeated-flex resistance1–5 | Below average — no S-N curve found; elongation at break 4 %, well below unfilled ABS[1][31] | Poor — no grade-specific S-N curve; plain printed PLA ran 38 000–49 000 cycles at 30 % of tensile strength (R = 0.2)[36][25] |
| Elasticity / flexibility1–5 | Rigid[1] | Rigid[2] |
| Z strength as % of XY% | Not documented | 76 by tensile, 40 by flexural (printed, Bambu Lab)[2] |

| HDT at 1.8 MPa°C | Not documented | 56 (ISO 75, 1.8 MPa)[2] |
| Glass transition (Tg)°C | 105 (DSC)[1] | 57 (DSC)[2] |
| Melting point / Vicat°C | Not documented | 158 peak melt (DSC); Vicat 66 °C[2] |
| Continuous service temperature°C | Not documented | 50 — a loaded bar begins to move at this temperature (My Tech Fun, eSun eSilk PLA)[33] |
| Annealing response | Not documented | 50–55 °C for 6–12 h[2] |
| Flammability / UL 94 | Not documented | Flammable; no UL 94 rating published by the major brands[30][37] |
| Environment & Chemical | ||
| UV resistance1–5 | Not documented | Degrades within weeks outdoors[25][38] |
| Chemical resistance | Good against weak acids, weak alkalis, oils and grease; dissolved by acetone[39] | Good against weak acids, oils and grease; poor against strong acids and alkalis; dissolved by chloroform, THF and hot benzene[37][25] |
| Water / humidity resistance in service1–5 | Not documented | Good — insoluble in water[30] |
| Food contact | Not food safe — Polymaker cites potential chemical leaching[22] | Base resin is food-contact grade, but printed layer grooves harbour bacteria; Prusa advises against food use[25] |
| Biodegradability / compostability | Not biodegradable[22] | Industrially compostable only — needs sustained 55 °C; not home compostable[40][25] |
| Recyclability | Mechanically recyclable but not accepted in household plastic collection[22] | Mechanically recyclable; not accepted in household plastic collection[40] |
| Electrical & ESD properties | Surface resistance 10⁷–10⁹ ohm/sq, the static-dissipative band (ASTM D257), against above 10¹³ for unfilled ABS[1][31] | Not documented |
| Health & Safety | ||
| Fume toxicity1–5 | High — hazardous VOC such as styrene; enclosure and filtration needed[41][18] | Low hazard — minimal VOC and particle emission[41] |
| VOC emission rateµg/min | 12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[41] | 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[41] | 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[41][18] | Not documented |
| Ventilation / filtration requirement1–5 | Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[41][18] | None needed in a normal room[41] |
| Dust & fibre handling hazard | Conductive carbon filler is bound in the matrix; avoid inhaling sanding dust[1] | Not documented |
| Post-Processing | ||
| Sanding & machining | Sands well and takes filler before painting[22] | Wet sanding — dry sanding heats the surface by friction and smears it[38][25] |
| Painting & finishing | Paints readily after light abrasion[22] | Not documented |
| Gluing & solvent welding | Not documented | Cyanoacrylate for most joints; some grades partially dissolve and bond with acetone[25][42] |
| Vapour / chemical smoothing | Not documented | No practical vapour smoothing — only chloroform, hot benzene or THF, which are laboratory-only[25] |
| Support material pairing | HIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[43][18] | Support for PLA (Bambu Lab)[2] |
| Dimensional accuracy & detail | Not documented | 55° overhangs and 30 mm bridges; gloss hides fine detail and is destroyed by sanding[2] |
| Solvents & Solubility | ||
| Soluble in | Acetone dissolves it — the basis of ABS slurry; so do MEK, THF, ethyl acetate, chloroform, dichloromethane and toluene.[44][39] | Chloroform: 10 % w/v in 2–4 h at 23 °C, every grade and morphology; THF and DMF only at 65 °C. Laboratory reagents.[45] |
| Softened or crazed by | Petrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[44][46] | Acetone, ethyl acetate and toluene plasticise it but dissolve <1 % even at 65 °C; submersion in acetone crazes and destroys parts.[45][47] |
| Solvent welding & smoothing agent | Acetone: about 20 min of vapour at 80 °C over 5 mm of liquid. Prusa measured layer adhesion more than doubled.[47] | Chloroform vapour smooths and welds PLA at the cost of tensile strength; acetone does not smooth it at all.[48][47] |
