Bed-adhesion difficulty1–5Needs a specific surface plus adhesive[17]Needs the right surface or a thin adhesive[3]
Stringing / oozing tendency1–5Slight — HIPS oozes less than ABS[17][20]Slight — the fibre reduces stringing against unfilled PETG[3][21]
Overall printing difficulty1–5Intermediate — dry filament and a tuned profile[18]Intermediate — dry filament and a tuned profile; hardened nozzle mandatory[3]
Hardware Wear & Reliability
Nozzle hardness required1–4Brass fine indefinitely[18]Hardened steel required[3]
Abrasiveness1–5Non-abrasive[18]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[17][22][2]Moderate — needs dry filament and a clean nozzle; 3DXTech specifies a hardened 0.4 mm minimum nozzle and 0.25 mm layers or higher, and Prusa lists composites as a higher clogging risk[23][24]
Heat-creep / jam sensitivity1–5Slightly sensitive[17]Slightly sensitive[21]
Hotend requirementNo special hot-end required[17]Hardened steel nozzle; no high-temperature hot-end needed[3][21]

Symptoms when wetBubbling and popping at the nozzle, stringing and a rough surface[25]Bubbling and popping at the nozzle, stringing and a rough surface[25]
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[25]No dry-versus-conditioned figures published; Bambu Lab states PETG-CF must be properly dried before printing and stored dry after use[3][25]
Storage requirementSealed with desiccant; less critical than for the polyamides[25]Sealed with desiccant; Bambu Lab says store dry after use[3][25]
Mechanical Properties
Tensile strength (XY)MPa40 at break (printed XY, ISO 527)[1]35 ± 5 (Bambu Lab) and 47 ± 2 at yield (Prusament) printed XY, ISO 527; 56 at break for 3DXTech[3][4][5]

Brittleness1–5Tough — absorbs impact, yields before breaking[1]Brittle — snaps with little warning[5]
Hardness (scale-specific)Shore A / Shore D / RockwellNot documented77 Shore D (Prusa Polymers method)[4]
Creep resistance / sustained load1–5Moderate — no printed-HIPS creep test found; Tg of 100 °C keeps room-temperature service far below softening[1][17]Below average — a 12 mm bar sagged to 16.4 mm over 5 days at 1.25 kg, less than plain PETG's 19.4[19]
Fatigue / repeated-flex resistance1–5Moderate[1]Moderate — no CF-grade S-N curve; unfilled printed PETG ran 79 000–193 000 cycles at 30 % of tensile strength[26]

Glass transition (Tg)°C100 (DSC)[1]68 (Bambu Lab) and 80 (3DXTech), DSC[3][5]
Melting point / Vicat°CAmorphous — no melting point[1]225 melting (Bambu Lab, DSC) — the carbon fibre lets the PET fraction crystallise[3]
Continuous service temperature°CBounded by a glass transition of 100 °C; no loaded-bar service figure is published for HIPS[1]77 — loaded bars begin to move at this temperature, against 61 for Bambu Lab PETG Basic[19]
Flammability / UL 94Flammable; no UL 94 rating published[1]Flammable; no UL 94 rating published[3]
Environment & Chemical
UV resistance1–5Months outdoors before embrittlement — polystyrene yellows and chalks under UV[27]Moderate — a season or two; the carbon fibre does not add UV stabilisation[28]
Chemical resistanceDissolves completely in d-limonene — the basis of its use as a soluble support[2]Withstands acids, alkalis, oils and UV exposure, as for unfilled PETG[28]
Food contactNot food safe[27]Not certified for food contact[28]
Biodegradability / compostabilityNot biodegradable[27]Not biodegradable[28]
RecyclabilityNot accepted in household plastic collection[27]Fibre-filled PETG is not accepted in household plastic collection[28]
Electrical & ESD propertiesSurface resistance above 10¹³ ohm/sq — insulating (ASTM D257)[1]Surface resistance above 10⁹ ohm/sq — carbon fibre at this loading is not static-dissipative (3DXTech)[5]
Health & Safety
Fume toxicity1–5High — hazardous VOC such as styrene; enclosure and filtration needed[29]Moderate — measurable VOCs and UFPs, ventilation advised[29]
VOC emission rateµg/min12–113 styrene, the range measured across ABS and the one HIPS filament tested[29]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[29]Not documented
Hazardous species emittedStyrene was the only dominant VOC identified for the HIPS filament tested[29]Not documented
Ventilation / filtration requirement1–5Enclosure with carbon and HEPA filtration[29]Open a window / occasional ventilation[29]
Dust & fibre handling hazardNot documentedCarbon fibre is bound in the matrix; sanding dust should not be inhaled[5]
Post-Processing
Sanding & machiningSands and paints readily, like ABS[27]Sands to a matte finish more readily than unfilled PETG[21]
Gluing & solvent weldingSolvent-welds with d-limonene, and with acetone via its polystyrene backbone[17][2]Cyanoacrylate; no common solvent welds it[21]
Vapour / chemical smoothingd-limonene attacks the surface; acetone smoothing is far less effective than on ABS[2][17]No practical vapour smoothing[21]
Support material pairingUsed as the support material itself — dissolves in d-limonene, or breaks away from ABS and ASA[2]Support for PLA or its own material (Bambu Lab)[3]
Dimensional accuracy & detailNot documentedMatte finish hides layer lines; stringing is reduced against unfilled PETG[3]
Solvents & Solubility
Soluble ind-limonene, 12–24 h submerged with occasional agitation; acetone also dissolves it, and xylene does so at 23 °C.[30][31][32]No common workshop solvent; dichloromethane — a carcinogen — dissolves the matrix surface, 1,2-dichloroethane destroys it in a week.[33][34]
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.[35]Acetone (+16 % weight over 1 year at 23 °C), ethyl acetate, toluene and DMF swell and soften it; methanol crazes it.[33]
Solvent welding & smoothing agentLimonene welds and lightly etches it; acetone welds through the polystyrene backbone but smooths less well than ABS.[30][35]Dichloromethane reaches only the resin, so the fibre is left standing proud of the surface. Controlled carcinogen.[34]
