Diameter tolerance± mmNot documented+/- 0.03 (Prusament PVB)[5]
Printing Parameters
Nozzle temperature°C270–290 (ABS Pro); 270–300 (ABS Max) — 25–35 °C above plain ABS[1][2]215 +/- 10 (Prusament PVB)[5]

Enclosure / chamber requirement1–5Enclosure required (passive)[1][2][10]Open frame is fine[4]
Part cooling fanNot documented100 % part cooling (Prusament PVB)[5]
Bed surface & adhesion aidClean the plate and apply glue; Simplify3D also lists Kapton tape and ABS slurry[10][11]Smooth PEI sheet or satin sheet; Prusa states a brim is not generally necessary[5]
Maximum volumetric flow (mm³/s; see test conditions)mm³/sUp to 250 mm/s (ABS Pro) and 200 mm/s (ABS Max), equivalent to 20 and 16 on a 0.4 mm nozzle at 0.2 mm layer[1][2][12]Not documented
Warping tendency1–5High — enclosure needed for reliable large parts[10]Not documented

Stringing / oozing tendency1–5Slight — Polymaker advises 1–2 mm retraction at 20–30 mm/s[13]Not documented
Overall printing difficulty1–5Intermediate — dry filament and a tuned profile; the hotter nozzle rules out PTFE-lined hotends[1][2]Easy — minor profile tuning; it prints close to PLA[4]
Hardware Wear & Reliability
Nozzle hardness required1–4Brass fine indefinitely[10]Brass fine indefinitely[4]
Abrasiveness1–5Non-abrasive[10]Non-abrasive[4]
Nozzle clog risk1–5Low — unfilled ABS compound; no special hot-end required and clogging is not among the listed drawbacks[11][14]Moderate — needs dry filament and a clean nozzle; Prusa calls PVB very prone to absorbing moisture and requires a 60 °C, 4 h dry before every print[15][16]

Symptoms when wetBubbling and popping at the nozzle, stringing and a rough surface[16]Not documented
Effect of moisture on strengthPolymaker rates ABS moderate-sensitivity and publishes no dry-versus-conditioned figures[16]Polymaker publishes no dry-versus-conditioned figures; at 2.36 % equilibrium uptake the material has to be kept dry to print cleanly[4][16]

Environment & Chemical
UV resistance1–5Months outdoors before embrittlement[13]Not documented
Chemical resistanceGood against weak acids, weak alkalis, oils and grease; dissolved by acetone[3]Not documented
Food contactNot food safe — Polymaker cites potential chemical leaching[13]Not documented
Biodegradability / compostabilityNot biodegradable[13]Not documented
RecyclabilityMechanically recyclable but not accepted in household plastic collection[13]Not documented
Health & Safety
Fume toxicity1–5High — hazardous VOC such as styrene; enclosure and filtration needed[20][10]Low hazard — minimal VOC and particle emission; none of these materials was in the chamber study[20]
VOC emission rateµg/min12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[20]Not documented
Ultrafine-particle emission rateparticles/min2 × 10¹⁰ to 9 × 10¹⁰ median across all ABS printers, two orders of magnitude above PLA's ≈1 × 10⁸[20]Not documented
Hazardous species emittedStyrene 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[20][10]Not documented
Ventilation / filtration requirement1–5Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[20][10]Open a window / occasional ventilation[20]
Post-Processing
Sanding & machiningSands well and takes filler before painting[13]Not documented
Painting & finishingPaints readily after light abrasion[13]Not documented
Vapour / chemical smoothingAcetone vapour smoothing works[3]Isopropyl alcohol vapour smoothing is the point of the material — Polymaker markets PolySmooth for hands-free post-processing to a layer-free surface[4]
Support material pairingHIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[21][10]PolyDissolve S1 is rated for PVB (Polymaker)[22]
Dimensional accuracy & detailNot documentedPolyCast is the investment-casting variant of the same chemistry — it burns out cleanly rather than being smoothed[17]
Solvents & Solubility
Soluble inAcetone dissolves it — the basis of ABS slurry; so do MEK, THF, ethyl acetate, chloroform, dichloromethane and toluene.[23][3]Isopropyl alcohol dissolves it; Prusa describes PVB as soluble only in IPA, and it is not water-soluble.[15]
Softened or crazed byPetrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[23][24]Not documented
Solvent welding & smoothing agentAcetone: about 20 min of vapour at 80 °C over 5 mm of liquid. Prusa measured layer adhesion more than doubled.[25]Isopropyl alcohol: brushed or sprayed on for speed, or several hours in IPA vapour for a glass-like surface.[25][15]
