Nozzle hardness required1–4Brass fine indefinitely[12]Brass fine indefinitely for unfilled grades[16]
Abrasiveness1–5Non-abrasive[12]Non-abrasive when unfilled[16]
Nozzle clog risk1–5Low — no special hot-end required, no drybox and no hardened nozzle, and 3DXTech states drying is not needed[11][17][2]Very high — frequent jams without careful setup[18][15]
Heat-creep / jam sensitivity1–5Slightly sensitive[11]Not documented
Hotend requirementNo special hot-end required[11]Not documented
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5Low (0.1–0.3 %) — Simplify3D lists water resistance as a headline property[11]Very high (>2 %) — Polymaker's own wet-state specimens reached 6.16 % moisture content after 48 h immersion at 60 °C[3][15]
Drying temperature & timeNot documented100 °C for 8 h (Polymaker CoPA)[3]
Symptoms when wetBubbling and popping at the nozzle, stringing and a rough surface[15]Popping and cracking during extrusion, then hard-to-diagnose defects[18]
Effect of moisture on strengthPolymaker 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[15]Measured dry against wet on printed specimens at 6.16 % moisture (Polymaker CoPA): tensile 78.0 → 34.3 MPa, Young's modulus 2703 → 724 MPa, flexural strength 109.8 → 22.6 MPa, while notched Charpy rises 6.9 → 27.7 kJ/m² and elongation 12.7 → 13.2 %[3][18]
Storage requirementSealed with desiccant; less critical than for the polyamides[15]Polymaker states CoPA must always be stored and used below 20 % relative humidity[3]
Hydrolysis at melt temperatureNot documentedPolymaker requires a 100 °C dry for 8 h and storage below 20 % RH; no molecular-weight loss figure is published, and the published wet data is conditioning rather than melt hydrolysis[3][19]

Health & Safety
Fume toxicity1–5High — hazardous VOC such as styrene; enclosure and filtration needed[22]Moderate — measurable VOCs and UFPs, ventilation advised[22]
VOC emission rateµg/min12–113 styrene, the range measured across ABS and the one HIPS filament tested[22]Up to 180 caprolactam, the dominant VOC from nylon; total VOC reached nearly 200 µg/min, the highest of the nine filaments tested[22]
Ultrafine-particle emission rateparticles/min≈4 × 10⁹ median for the HIPS filament tested, an order of magnitude below ABS but forty times PLA[22]≈2 × 10⁸ median — low for ultrafine particles despite the highest VOC mass of any filament tested[22]
Hazardous species emittedStyrene was the only dominant VOC identified for the HIPS filament tested[22]Caprolactam, at up to 180 µg/min from nylon filament — the largest single-VOC emission rate measured in the study[22]
Ventilation / filtration requirement1–5Enclosure with carbon and HEPA filtration[22]Ventilated room or enclosure recommended[22]
Post-Processing
Sanding & machiningSands and paints readily, like ABS[21]Not documented
Gluing & solvent weldingSolvent-welds with d-limonene, and with acetone via its polystyrene backbone[11][2]Not documented
Vapour / chemical smoothingd-limonene attacks the surface; acetone smoothing is far less effective than on ABS[2][11]Not documented
Support material pairingUsed as the support material itself — dissolves in d-limonene, or breaks away from ABS and ASA[2]CoPA can support itself, but Polymaker warns the support bonds permanently if it absorbs moisture before removal[3]
Solvents & Solubility
Soluble ind-limonene, 12–24 h submerged with occasional agitation; acetone also dissolves it, and xylene does so at 23 °C.[23][24][25]Dissolved at 23 °C by formic acid above ~50 %, phenol, m-cresol, 96 % sulphuric acid or hexafluoroisopropanol — laboratory reagents.[26]
Softened or crazed byLimonene also disrupts layer adhesion in some ABS and ASA grades, so an ABS model can flake apart in the same bath.[27]Zinc chloride solutions stress-crack it — 10 % marginal, 37 % not resistant; alcoholic calcium chloride dissolves it.[26]
Solvent welding & smoothing agentLimonene welds and lightly etches it; acetone welds through the polystyrene backbone but smooths less well than ABS.[23][27]None — nylon's only solvents are formic acid, phenol and HFIP, all of which degrade the part they wet.[26]
