| Typical priceUSD/kg | 1 kg-equivalent spools span 45–120; the middle of the market is about 52[6][7][8][9] | 1 kg spools cluster near 30[10][11] |
| Price range across brandsUSD/kg | 45–120 across brands; SUNLU 45, YXPOLYER 50, Coex 3D 52, 3DXTech 107 at 750 g pricing; the FR PC/ABS grade runs 120[6][7][8][9] | 30–60 across brands; Polymaker 30, Proto-pasta 60[10][11] |

| Drying temperature & time | Not documented | 60 °C for 6 h (Polymaker HT-PLA-GF)[2] |
| Symptoms when wet | Bubbling and popping at the nozzle, stringing and a rough surface[22] | Not documented |

| Biodegradability / compostability | Not biodegradable[16] | Not documented |
| Recyclability | Mechanically recyclable but not accepted in household plastic collection[16] | Not documented |
| Health & Safety | ||
| Fume toxicity1–5 | High — hazardous VOC such as styrene; enclosure and filtration needed[30][13] | Low hazard — minimal VOC and particle emission[30] |
| VOC emission rateµg/min | 12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[30] | 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[30][13] | Not documented |
| Ventilation / filtration requirement1–5 | Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[30][13] | None needed in a normal room[30] |

| Sanding & machining | Sands well and takes filler before painting[16] | Not documented |
| Painting & finishing | Paints readily after light abrasion[16] | Not documented |
| Support material pairing | HIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[32][13] | Not documented |
| Dimensional accuracy & detail | Not documented | Near-zero shrinkage — 0.05 % in X-Y and Z (Polymaker)[2] |
| Solvents & Solubility | ||
| Soluble in | Acetone dissolves it — the basis of ABS slurry; so do MEK, THF, ethyl acetate, chloroform, dichloromethane and toluene.[33][29] | Chloroform dissolves the PLA matrix (10 % w/v, 2–4 h at 23 °C) and leaves the filler as loose sludge; laboratory reagent.[34] |
| Softened or crazed by | Petrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[33][35] | Acetone, ethyl acetate and toluene plasticise the matrix but dissolve <1 % even at 65 °C; acetone submersion crazes parts.[34][36] |
| 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.[36] | Chloroform vapour attacks only the resin fraction, so the filler is left standing proud; no workshop-safe agent exists.[37][36] |
