| Bed surface & adhesion aid | Glue stick, glass plate, Kapton tape or PET sheets[13] | Textured PEI, satin or powder-coated sheets; on smooth PEI a glue stick acts as a release agent[12][15] |
| Warping tendency1–5 | Moderate — needs adhesion aid or draught shield[14] | Not documented |
| Bed-adhesion difficulty1–5 | Needs a specific surface plus adhesive[13] | Needs the right surface or a thin adhesive — the problem is releasing the part, not sticking it[12][15] |
| Stringing / oozing tendency1–5 | Slight — HIPS oozes less than ABS[13][16] | Moderate — retraction tuning needed; Polymaker names stringing as PETG's common quirk[15] |
| Overall printing difficulty1–5 | Intermediate — dry filament and a tuned profile[14] | Easy — minor profile tuning; Spectrum describes printing as similar to standard PETG[4] |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Brass fine indefinitely[14] | Brass fine indefinitely[3] |
| Abrasiveness1–5 | Non-abrasive[14] | Not documented |
| Nozzle clog risk1–5 | Low — no special hot-end required, no drybox and no hardened nozzle, and 3DXTech states drying is not needed[13][17][2] | Low — recycled PETG prints on the same hardware as virgin PETG: no special hot-end, no drybox and no hardened nozzle[18][17] |
| Heat-creep / jam sensitivity1–5 | Slightly sensitive[13] | Slightly sensitive[18] |
| Hotend requirement | No special hot-end required[13] | No special hot-end required[18] |
| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | Low (0.1–0.3 %) — Simplify3D lists water resistance as a headline property[13] | Moderate (0.3–0.8 %) — recycled PETG shares the virgin matrix, which reaches 0.40 % saturated at 25 °C / 55 % RH[12] |

| Symptoms when wet | Bubbling and popping at the nozzle, stringing and a rough surface[19] | Bubbling and popping at the nozzle, stringing and a rough surface[19] |
| 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[19] | Polymaker groups PETG with nylon, PVA and TPU as highly hygroscopic; no dry-versus-conditioned strength figures are published for this grade and the loss shows as bubbling and poor layer adhesion[19] |
| Storage requirement | Sealed with desiccant; less critical than for the polyamides[19] | Sealed with desiccant; Polymaker groups PETG with the highly hygroscopic materials[19][15] |
| Mechanical Properties | ||
| Tensile strength (XY)MPa | 40 at break (printed XY, ISO 527)[1] | 43 ± 1.8 printed horizontal at yield, ISO 527-1 (Prusament), against 47 ± 2 for virgin Prusament PETG; Spectrum quotes 52 at yield on moulded specimens[3][12][4] |
| Young's modulusMPa | 1350 (printed XY, ISO 527) — the lowest modulus of the styrenics here[1] | 1500 printed horizontal, 1600 printed vertical (Prusament, ISO 527-1) — the same as virgin Prusament PETG[3][12] |
| Elongation at break% | 18 at break (printed XY, ISO 527)[1] | 4.5 at yield printed (Prusament); Spectrum quotes 400 at break on moulded specimens[3][4] |

| Brittleness1–5 | Tough — absorbs impact, yields before breaking[1] | Moderate[3] |
| Hardness (scale-specific)Shore A / Shore D / Rockwell | Not documented | 74 Shore D (Prusa Polymers method) — the same as virgin Prusament PETG[3][12] |
| Creep resistance / sustained load1–5 | Moderate — no printed-HIPS creep test found; Tg of 100 °C keeps room-temperature service far below softening[1][13] | Below average — no recycled-grade creep test; virgin PETG sagged from 12 to 17.1–20.4 mm over 5 days at 1.25 kg[20][21][22][23] |
| Fatigue / repeated-flex resistance1–5 | Moderate[1] | Moderate — no recycled-grade S-N curve; virgin printed PETG ran 79 000–193 000 cycles at 30 % of tensile strength[24] |
| Elasticity / flexibility1–5 | Rigid[1] | Slightly flexible in thin sections[3] |
| Thermal Properties | ||
| HDT at 0.45 MPa°C | Not documented | 68 (ISO 75, 0.45 MPa) — the same as virgin Prusament PETG; Spectrum quotes 70[3][12][4] |
| HDT at 1.8 MPa°C | Not documented | 68 (ISO 75, 1.8 MPa)[3] |
| Glass transition (Tg)°C | 100 (DSC)[1] | Not documented |

| Electrical & ESD properties | Surface resistance above 10¹³ ohm/sq — insulating (ASTM D257)[1] | Not documented |
| Health & Safety | ||
| Fume toxicity1–5 | High — hazardous VOC such as styrene; enclosure and filtration needed[27] | Moderate — measurable VOCs and UFPs, ventilation advised[27] |
| VOC emission rateµg/min | 12–113 styrene, the range measured across ABS and the one HIPS filament tested[27] | Not documented |
| Ultrafine-particle emission rateparticles/min | ≈4 × 10⁹ median for the HIPS filament tested, an order of magnitude below ABS but forty times PLA[27] | Not documented |
| Hazardous species emitted | Styrene was the only dominant VOC identified for the HIPS filament tested[27] | Not documented |
| Ventilation / filtration requirement1–5 | Enclosure with carbon and HEPA filtration[27] | Open a window / occasional ventilation[27] |
| Post-Processing | ||
| Sanding & machining | Sands and paints readily, like ABS[26] | Sands poorly — the material is tough and gums rather than powders[18] |
| Gluing & solvent welding | Solvent-welds with d-limonene, and with acetone via its polystyrene backbone[13][2] | Cyanoacrylate; no common solvent welds PETG cleanly[18] |
| Vapour / chemical smoothing | d-limonene attacks the surface; acetone smoothing is far less effective than on ABS[2][13] | No practical vapour smoothing[18] |
| Support material pairing | Used as the support material itself — dissolves in d-limonene, or breaks away from ABS and ASA[2] | Prints its own supports; Polymaker rates PolyDissolve S1 for PETG[18] |
| Solvents & Solubility | ||
| Soluble in | d-limonene, 12–24 h submerged with occasional agitation; acetone also dissolves it, and xylene does so at 23 °C.[28][29][30] | No common workshop solvent; 1,2-dichloroethane destroys it inside a week and dichloromethane — a carcinogen — dissolves the surface.[31][32] |
| 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.[33] | Acetone (+16 % weight over 1 year at 23 °C), ethyl acetate, toluene and DMF swell and soften it; methanol crazes it.[31] |
| Solvent welding & smoothing agent | Limonene welds and lightly etches it; acetone welds through the polystyrene backbone but smooths less well than ABS.[28][33] | Dichloromethane brushed on is the only agent that smooths PETG — a controlled carcinogen, not workshop stock.[32] |
