| Stringing / oozing tendency1–5 | Slight — Polymaker advises 1–2 mm retraction at 20–30 mm/s[20] | Not documented |
| Overall printing difficulty1–5 | Intermediate — dry filament and a tuned profile; the hotter nozzle rules out PTFE-lined hotends[1][2] | Intermediate — dry filament and a tuned profile; brittle in filament form and slow to print[6][10] |
| Extruder requirement | Not documented | Proto-pasta advises an extrusion width 0.05 mm larger than the nozzle and warns that feeding is inconsistent below 0.4 mm and on Bowden machines[6][10] |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Brass fine indefinitely[17] | Brass acceptable; hardened steel for volume work[6][10] |
| Abrasiveness1–5 | Non-abrasive[17] | Moderately abrasive — metal fill[6][10] |
| Nozzle clog risk1–5 | Low — unfilled ABS compound; no special hot-end required and clogging is not among the listed drawbacks[18][21] | Moderate — needs dry filament and a clean nozzle[10] |
| Heat-creep / jam sensitivity1–5 | Slightly sensitive[18] | Not documented |
| Hotend requirement | No special hot-end required[18] | Proto-pasta recommends a wear-resistant or larger nozzle for longer service intervals[6][10] |

| Thermal expansion (CTE)µm/m·K | 86–89 for printed unfilled ABS (fibre Bragg grating, 25–50 °C); no grade-specific measurement published[30] | Not documented |
| Environment & Chemical | ||
| UV resistance1–5 | Months outdoors before embrittlement[20] | Degrades within weeks outdoors[31] |
| Outdoor durability | Not documented | Proto-pasta markets its iron grade as rustable — the iron oxidises deliberately when exposed to moisture[6] |
| Chemical resistance | Good against weak acids, weak alkalis, oils and grease; dissolved by acetone[3] | Not documented |
| Food contact | Not food safe — Polymaker cites potential chemical leaching[20] | Not documented |
| Biodegradability / compostability | Not biodegradable[20] | Not documented |
| Recyclability | Mechanically recyclable but not accepted in household plastic collection[20] | Not documented |
| Electrical & ESD properties | Not documented | Proto-pasta magnetic iron PLA is ferromagnetic and responds to magnets[6] |
| Health & Safety | ||
| Fume toxicity1–5 | High — hazardous VOC such as styrene; enclosure and filtration needed[32][17] | Low hazard — minimal VOC and particle emission[32] |
| VOC emission rateµg/min | 12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[32] | 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[32] | 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[32][17] | Not documented |
| Ventilation / filtration requirement1–5 | Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[32][17] | None needed in a normal room[32] |
| Post-Processing | ||
| Sanding & machining | Sands well and takes filler before painting[20] | Polishing is the intended finish — colorFabb and Proto-pasta both sell these grades to be sanded and buffed to a metallic shine[4][5][10] |
| Painting & finishing | Paints readily after light abrasion[20] | Not documented |
| Vapour / chemical smoothing | Acetone vapour smoothing works[3] | Not documented |
| Support material pairing | HIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[33][17] | Not documented |
| Dimensional accuracy & detail | Not documented | colorFabb notes the metal fill increases die swell, so flow needs raising above plain PLA[5] |
| Solvents & Solubility | ||
| Soluble in | Acetone dissolves it — the basis of ABS slurry; so do MEK, THF, ethyl acetate, chloroform, dichloromethane and toluene.[34][3] | Chloroform dissolves the PLA matrix (10 % w/v, 2–4 h at 23 °C) and leaves the filler as loose sludge; laboratory reagent.[35] |
| Softened or crazed by | Petrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[34][36] | Acetone, ethyl acetate and toluene plasticise the matrix but dissolve <1 % even at 65 °C; acetone submersion crazes parts.[35][37] |
| 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.[37] | Chloroform vapour attacks only the resin fraction, so the filler is left standing proud; no workshop-safe agent exists.[38][37] |
