| Enclosure / chamber requirement1–5 | Enclosure recommended — Bambu Lab specifies a 45–60 °C chamber[2][13] | Enclosure recommended — Simplify3D lists an enclosure as a hardware requirement and Polymaker advises one below 70 °C ambient to stop warping and cracking[14][15] |
| Recommended chamber temperature°C | 45–60 (Bambu Lab)[2] | Not documented |
| Part cooling fan | 0–80 % (Bambu Lab)[2] | Off — Prusa runs 0 % except 100 % on bridges[3] |

| Maximum volumetric flow (mm³/s; see test conditions)mm³/s | 14 at Bambu Lab's 180 mm/s cap on a 0.4 mm nozzle at 0.2 mm layer[2][17] | 4 at Prusa's 50 mm/s cap on a 0.4 mm nozzle at 0.2 mm layer[3][17] |

| Nozzle hardness required1–4 | Hardened steel required[13] | Hardened steel required[3] |
| Abrasiveness1–5 | Highly abrasive — standard GF composite[13] | Highly abrasive — standard GF composite[3] |
| Nozzle clog risk1–5 | Moderate — needs dry filament and a clean nozzle; 3DXTech specifies a hardened 0.4 mm minimum nozzle and 0.25 mm layers or higher for the glass-filled grade[19][20] | Moderate — needs dry filament and a clean nozzle; Prusa lists higher risk of nozzle clogging for glass-filled composites[20] |
| Heat-creep / jam sensitivity1–5 | Slightly sensitive[16] | Not documented |
| Hotend requirement | No special hot-end required[16] | Not documented |
| Moisture Behaviour | ||

| 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 glass-fibre PP filament[23] |

| Elasticity / flexibility1–5 | Rigid[2] | Rigid[3] |
| Z strength as % of XY% | 81 (Bambu Lab, printed Z against XY tensile)[2] | Not documented |

| Biodegradability / compostability | Not biodegradable[18] | Not documented |
| Recyclability | Mechanically recyclable but not accepted in household plastic collection[18] | Not documented |
| Health & Safety | ||
| Fume toxicity1–5 | High — hazardous VOC such as styrene; enclosure and filtration needed[25][13] | 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[25] |
| VOC emission rateµg/min | 12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[25] | 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[25] | 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[25][13] | Not documented |
| Ventilation / filtration requirement1–5 | Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[25][13] | Open a window / occasional ventilation. Inferred — no polyolefin was measured in the chamber study[25] |
| Dust & fibre handling hazard | Glass fibre is bound in the matrix; avoid inhaling sanding dust[1] | Glass fibre is bound in the matrix; avoid inhaling sanding dust[3] |
| Post-Processing | ||
| Sanding & machining | Sands well and takes filler before painting[18] | Not documented |
| Painting & finishing | Paints readily after light abrasion[18] | Not documented |
| Support material pairing | HIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[26][13] | Not documented |
| Dimensional accuracy & detail | Bambu Lab describes a smooth matte finish with micro-spot gloss that blurs layer lines[2] | Not documented |
| Solvents & Solubility | ||
| Soluble in | Acetone dissolves the resin and leaves the fibre as sludge; MEK, THF, ethyl acetate and chlorinated solvents do the same.[27][24] | None at room temperature; chloroform dissolves the matrix at 60 °C and xylene at about 118 °C, leaving the fibre.[28][29] |
| Softened or crazed by | Petrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[27][30] | Xylene, decalin, CCl4 and chlorobenzene are heavily absorbed at 20 °C; oleum, chlorosulphonic acid and bromine destroy it.[28] |
| Solvent welding & smoothing agent | Acetone vapour reaches only the resin fraction, so the fibre is left standing proud of the smoothed surface.[31][24] | None — nothing softens PP at room temperature, so joints have to be welded thermally rather than chemically.[28] |
