Typical applicationsBreak-away and d-limonene-soluble support for ABS and ASA, and a light model material in its own right[2]Load-bearing parts that must survive above PETG's 70 °C ceiling without moving to PA or PC[3][4]
Printing Parameters
Nozzle temperature°C230–245 (Simplify3D)[10]260–290 (Bambu Lab)[3]
Bed temperature°C100–115 (Simplify3D)[10]80–100 (Bambu Lab)[3]
Enclosure / chamber requirement1–5Enclosure recommended[11]Enclosure recommended — Bambu Lab specifies a 45–60 °C chamber[3]
Recommended chamber temperature°CNot documented45–60 (Bambu Lab)[3]
Part cooling fanPart cooling fan not required[10]0–60 % (Bambu Lab)[3]
Bed surface & adhesion aidGlue stick, glass plate, Kapton tape or PET sheets[10]Textured PEI, satin or powder-coated sheets; on smooth PEI a glue stick acts as a release agent[12][13]
Maximum volumetric flow (mm³/s; see test conditions)mm³/sNot documented8 at Bambu Lab's 100 mm/s cap on a 0.4 mm nozzle at 0.2 mm layer — half the speed it allows for PETG-CF[3][14]
Warping tendency1–5Moderate — needs adhesion aid or draught shield[11]Not documented
Bed-adhesion difficulty1–5Needs a specific surface plus adhesive[10]Needs the right surface or a thin adhesive — the problem is releasing the part, not sticking it[12][13]
Stringing / oozing tendency1–5Slight — HIPS oozes less than ABS[10][15]Moderate — retraction tuning needed; Polymaker names stringing as PETG's common quirk[13]
Overall printing difficulty1–5Intermediate — dry filament and a tuned profile[11]Advanced — enclosure, hardware upgrades, tuning[3]
Hardware Wear & Reliability
Nozzle hardness required1–4Brass fine indefinitely[11]Hardened steel required[3]
Abrasiveness1–5Non-abrasive[11]Highly abrasive — standard CF composite[3]
Nozzle clog risk1–5Low — no special hot-end required, no drybox and no hardened nozzle, and 3DXTech states drying is not needed[10][16][2]Moderate — needs dry filament and a clean nozzle; Prusa lists higher risk of nozzle clogging for carbon-filled composites[17]
Heat-creep / jam sensitivity1–5Slightly sensitive[10]Slightly sensitive[18]
Hotend requirementNo special hot-end required[10]No special hot-end required[18]
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5Low (0.1–0.3 %) — Simplify3D lists water resistance as a headline property[10]Moderate — 0.37 % saturated at 25 °C / 55 % RH (Bambu Lab); 0.53 % equilibrium (Fiberon)[3][4]
Equilibrium moisture content at ~50 % RH%Not documented0.37 saturated at 25 °C / 55 % RH (Bambu Lab); 0.53 equilibrium (Fiberon PET-CF17)[3][4]
Drying temperature & timeNot documented80 °C for 8–12 h (Bambu Lab) — the longest and hottest dry in the polyester family; Fiberon specifies 100 °C for 10 h[3][4]
Symptoms when wetBubbling 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 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[19]Bambu Lab publishes its whole mechanical table under the heading "Mechanical Properties (Dry state)" — the quoted figures apply only to dried filament[3]
Storage requirementSealed with desiccant; less critical than for the polyamides[19]Sealed with desiccant; Polymaker groups PETG with the highly hygroscopic materials[19][13]
Hydrolysis at melt temperatureNot documentedThe 80–100 °C dry both suppliers mandate is far above the 55–65 °C used for PETG, consistent with a melt-hydrolysis risk in the semi-crystalline PET matrix; neither publishes a molecular-weight loss figure[3][4]
Mechanical Properties
Tensile strength (XY)MPa40 at break (printed XY, ISO 527)[1]65.9 (Fiberon) to 74 (Bambu Lab) printed XY, ISO 527[3][4]

Brittleness1–5Tough — absorbs impact, yields before breaking[1]Very brittle — elongation at break 2.4 % in XY and 0.8 % in Z[4]
Creep resistance / sustained load1–5Moderate — no printed-HIPS creep test found; Tg of 100 °C keeps room-temperature service far below softening[1][10]Good — no creep test found; annealed PET-CF holds a 105 °C HDT at 1.8 MPa and a 4730–5481 MPa modulus against 1500–2311 for PETG[4][3]
Fatigue / repeated-flex resistance1–5Moderate[1]Below average — no S-N curve; elongation at break is 2.4 % in XY and 0.8 % in Z, against 5.2–9.3 % for unfilled PETG[4]

Z strength as % of XY%Not documented42 (Fiberon) to 47 (Bambu Lab), printed[3][4]

Continuous service temperature°CBounded by a glass transition of 100 °C; no loaded-bar service figure is published for HIPS[1]Not documented
Annealing responseNot documentedThe PET matrix crystallises on annealing, which is what separates this grade from PETG-CF[4][3]
Flammability / UL 94Flammable; no UL 94 rating published[1]Flammable; no UL 94 rating published for standard grades[20]
Environment & Chemical
UV resistance1–5Months outdoors before embrittlement — polystyrene yellows and chalks under UV[21]Not documented

Electrical & ESD propertiesSurface resistance above 10¹³ ohm/sq — insulating (ASTM D257)[1]Surface resistivity above 10¹² ohm — insulating (Fiberon PET-CF17, ANSI/ESD S11.11)[4]
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]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[22]Not documented
Hazardous species emittedStyrene was the only dominant VOC identified for the HIPS filament tested[22]Not documented
Ventilation / filtration requirement1–5Enclosure with carbon and HEPA filtration[22]Ventilated room or enclosure recommended[22][3]
Dust & fibre handling hazardNot documentedCarbon fibre is bound in the matrix; sanding dust should not be inhaled[4]
Post-Processing
Sanding & machiningSands and paints readily, like ABS[21]Sands poorly — the material is tough and gums rather than powders[18]
Gluing & solvent weldingSolvent-welds with d-limonene, and with acetone via its polystyrene backbone[10][2]Cyanoacrylate; no common solvent welds PETG cleanly[18]
Vapour / chemical smoothingd-limonene attacks the surface; acetone smoothing is far less effective than on ABS[2][10]No practical vapour smoothing[18]
Support material pairingUsed 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]
Dimensional accuracy & detailNot documentedBambu Lab markets it on low warping and shrinkage relative to other high-temperature composites[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]None common; fluorinated solvents such as hexafluoroisopropanol dissolve linear polyester at 23 °C. Laboratory only.[26][24]
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]Ensinger rates polyester not resistant to chloroform or dichloromethane and only conditionally resistant to acetone and MEK.[24]
Solvent welding & smoothing agentLimonene welds and lightly etches it; acetone welds through the polystyrene backbone but smooths less well than ABS.[23][27]Dichloromethane attacks polyester and can be brushed on, but the carbon fibre blocks any useful surface flow.[24][28]
