Diameter tolerance± mmNot documented±0.04 (Prusament)[3]
Printing Parameters
Nozzle temperature°C230–245 (Simplify3D)[11]245 ± 10 (Prusament) — 25 °C below the carbon-fibre grade[3][12]
Bed temperature°C100–115 (Simplify3D)[11]95 ± 10 (Prusament)[3]
Enclosure / chamber requirement1–5Enclosure recommended[13]Enclosure recommended — Simplify3D lists an enclosure as a hardware requirement and Polymaker advises one below 70 °C ambient to stop warping and cracking[14][15]
Part cooling fanPart cooling fan not required[11]Off — Prusa runs 0 % except 100 % on bridges[3]
Bed surface & adhesion aidGlue stick, glass plate, Kapton tape or PET sheets[11]Not documented
Maximum volumetric flow (mm³/s; see test conditions)mm³/sNot documented4 at Prusa's 50 mm/s cap on a 0.4 mm nozzle at 0.2 mm layer[3][16]
Warping tendency1–5Moderate — needs adhesion aid or draught shield[13]High — enclosure needed for reliable large parts; Prusa recommends a brim[3]
Bed-adhesion difficulty1–5Needs a specific surface plus adhesive[11]Very difficult — special plates or slurry required[3]
Stringing / oozing tendency1–5Slight — HIPS oozes less than ABS[11][17]Not documented
Overall printing difficulty1–5Intermediate — dry filament and a tuned profile[13]Advanced — enclosure, hardware upgrades, tuning; hardened nozzle mandatory[3]
Extruder requirementNot documentedPrusa states a hardened nozzle is necessary and recommends a brim[3]
Hardware Wear & Reliability
Nozzle hardness required1–4Brass fine indefinitely[13]Hardened steel required[3]
Abrasiveness1–5Non-abrasive[13]Highly abrasive — standard GF composite[3]
Nozzle clog risk1–5Low — no special hot-end required, no drybox and no hardened nozzle, and 3DXTech states drying is not needed[11][18][2]Moderate — needs dry filament and a clean nozzle; Prusa lists higher risk of nozzle clogging for glass-filled composites[19]
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]Low (0.1–0.3 %) — 0.11 % at both 24 h and 7 days, higher than the carbon-fibre grade's 0.04 % but still very low[3][12]
Equilibrium moisture content at ~50 % RH%Not documented0.11 after 24 h and 0.11 after 7 days at 24 °C / 22 % RH (Prusa Polymers)[3]
Symptoms when wetBubbling and popping at the nozzle, stringing and a rough surface[20]Not documented
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[20]Not applicable in practice at 0.11 % equilibrium uptake[3]
Storage requirementSealed with desiccant; less critical than for the polyamides[20]No special storage needed[3]
Mechanical Properties

Brittleness1–5Tough — absorbs impact, yields before breaking[1]Moderate[3]
Hardness (scale-specific)Shore A / Shore D / RockwellNot documentedRockwell R102 (and M95) on extruded unfilled PP stock (ASTM D785); no figure is published for a glass-fibre PP filament[21]
Creep resistance / sustained load1–5Moderate — no printed-HIPS creep test found; Tg of 100 °C keeps room-temperature service far below softening[1][11]Not documented
Fatigue / repeated-flex resistance1–5Moderate[1]Not documented
Elasticity / flexibility1–5Rigid[1]Rigid[3]
Thermal Properties

Environment & Chemical
UV resistance1–5Months outdoors before embrittlement — polystyrene yellows and chalks under UV[22]Not documented

Food contactNot food safe[22]Not documented
Biodegradability / compostabilityNot biodegradable[22]Not documented
RecyclabilityNot accepted in household plastic collection[22]Not documented
Electrical & ESD propertiesSurface resistance above 10¹³ ohm/sq — insulating (ASTM D257)[1]Not documented
Health & Safety
Fume toxicity1–5High — hazardous VOC such as styrene; enclosure and filtration needed[23]Low hazard — minimal VOC and particle emission. Inferred: no polyolefin was among the nine filaments in the Azimi chamber study, so this is a family-level judgement rather than a measurement[23]
VOC emission rateµg/min12–113 styrene, the range measured across ABS and the one HIPS filament tested[23]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[23]Not documented
Hazardous species emittedStyrene was the only dominant VOC identified for the HIPS filament tested[23]Not documented
Ventilation / filtration requirement1–5Enclosure with carbon and HEPA filtration[23]Open a window / occasional ventilation. Inferred — no polyolefin was measured in the chamber study[23]
Dust & fibre handling hazardNot documentedGlass fibre is bound in the matrix; avoid inhaling sanding dust[3]
Post-Processing
Sanding & machiningSands and paints readily, like ABS[22]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]Not documented
Solvents & Solubility
Soluble ind-limonene, 12–24 h submerged with occasional agitation; acetone also dissolves it, and xylene does so at 23 °C.[24][25][26]None at room temperature; chloroform dissolves the matrix at 60 °C and xylene at about 118 °C, leaving the fibre.[27][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.[28]Xylene, decalin, CCl4 and chlorobenzene are heavily absorbed at 20 °C; oleum, chlorosulphonic acid and bromine destroy it.[27]
Solvent welding & smoothing agentLimonene welds and lightly etches it; acetone welds through the polystyrene backbone but smooths less well than ABS.[24][28]None — nothing softens PP at room temperature, so joints have to be welded thermally rather than chemically.[27]
