| Hotend requirement | No special hot-end required[9] | Not documented |
| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | Low (0.1–0.3 %) — Simplify3D lists water resistance as a headline property[9] | Very high (>2 %)[14] |
| Equilibrium moisture content at ~50 % RH% | Not documented | 8.5 at saturation on extruded PA66 stock (ASTM D570) — the highest uptake of any polymer in this dataset[4] |
| Symptoms when wet | Bubbling and popping at the nozzle, stringing and a rough surface[14] | Not documented |
| Effect of moisture on strength | Polymaker 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[14] | 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 %[15][13] |
| Storage requirement | Sealed with desiccant; less critical than for the polyamides[14] | Not documented |
| Mechanical Properties | ||
| Tensile strength (XY)MPa | 40 at break (printed XY, ISO 527)[1] | 82.7 at yield and 84.8 at break on extruded PA66 stock (ASTM D638; converted from 12,000 and 12,300 psi) — no printed figure exists because no unfilled PA66 filament was found[4] |

| Other impact data | Not documented | Izod 53 J/m on extruded PA66 stock, converted from 1.0 ft-lb/in (ASTM D256)[4] |
| Brittleness1–5 | Tough — absorbs impact, yields before breaking[1] | Not documented |
| Hardness (scale-specific)Shore A / Shore D / Rockwell | Not documented | Shore D 86 and Rockwell 85 (108) — the source does not name the scales on extruded PA66 stock (ASTM D2240, D785)[4] |
| Creep resistance / sustained load1–5 | Moderate — no printed-HIPS creep test found; Tg of 100 °C keeps room-temperature service far below softening[1][9] | Not documented |

| Elasticity / flexibility1–5 | Rigid[1] | Semi-flexible[13] |
| Wear resistance & friction | Not documented | Wear factor 200e-10 in3*min/(ft*lb*h) on extruded PA66 stock (ASTM D3702); Ensinger lists very good slide and wear properties[4] |
| Thermal Properties | ||
| HDT at 0.45 MPa°C | Not documented | 232 on extruded PA66 stock (ASTM D648 at 66 psi; converted from 450 °F)[4] |
| HDT at 1.8 MPa°C | Not documented | 90 on extruded PA66 stock (ASTM D648 at 264 psi; converted from 194 °F) — the gap to the 0.45 MPa figure is the widest in the dataset[4] |
| Glass transition (Tg)°C | 100 (DSC)[1] | Not documented |
| Melting point / Vicat°C | Amorphous — no melting point[1] | 255 melting on extruded PA66 stock (ASTM D2133; converted from 491 °F)[4] |
| Continuous service temperature°C | Bounded by a glass transition of 100 °C; no loaded-bar service figure is published for HIPS[1] | 85 long term and 149 short term on extruded PA66 stock (converted from 185 °F and 300 °F)[4] |

| Health & Safety | ||
| Fume toxicity1–5 | High — hazardous VOC such as styrene; enclosure and filtration needed[17] | Moderate — measurable VOCs and UFPs, ventilation advised[17] |
| VOC emission rateµg/min | 12–113 styrene, the range measured across ABS and the one HIPS filament tested[17] | Up to 180 caprolactam, the dominant VOC from nylon; total VOC reached nearly 200 µg/min, the highest of the nine filaments tested[17] |
| Ultrafine-particle emission rateparticles/min | ≈4 × 10⁹ median for the HIPS filament tested, an order of magnitude below ABS but forty times PLA[17] | ≈2 × 10⁸ median — low for ultrafine particles despite the highest VOC mass of any filament tested[17] |
| Hazardous species emitted | Styrene was the only dominant VOC identified for the HIPS filament tested[17] | Caprolactam, at up to 180 µg/min from nylon filament — the largest single-VOC emission rate measured in the study[17] |
| Ventilation / filtration requirement1–5 | Enclosure with carbon and HEPA filtration[17] | Ventilated room or enclosure recommended[17] |
| Post-Processing | ||
| Sanding & machining | Sands and paints readily, like ABS[16] | Not documented |
| Gluing & solvent welding | Solvent-welds with d-limonene, and with acetone via its polystyrene backbone[9][2] | Not documented |
| Vapour / chemical smoothing | d-limonene attacks the surface; acetone smoothing is far less effective than on ABS[2][9] | Not documented |
| Support material pairing | Used as the support material itself — dissolves in d-limonene, or breaks away from ABS and ASA[2] | Not documented |
| Solvents & Solubility | ||
| Soluble in | d-limonene, 12–24 h submerged with occasional agitation; acetone also dissolves it, and xylene does so at 23 °C.[18][19][20] | Dissolved at 23 °C by formic acid above ~80 %, phenol, m-cresol, 96 % sulphuric acid or hexafluoroisopropanol — laboratory reagents.[21] |
| Softened or crazed by | Limonene also disrupts layer adhesion in some ABS and ASA grades, so an ABS model can flake apart in the same bath.[22] | Zinc chloride solutions stress-crack it — 10 % marginal, 37 % not resistant; alcoholic calcium chloride dissolves it.[21] |
| Solvent welding & smoothing agent | Limonene welds and lightly etches it; acetone welds through the polystyrene backbone but smooths less well than ABS.[18][22] | None — nylon's only solvents are formic acid, phenol and HFIP, all of which degrade the part they wet.[21] |
