Market snapshot
Listing priceUSD/kg; dated snapshots$87.72/kg median; $87.72–$87.72/kg across 1 dated product listings$281.22/kg median; $195.00–$698.00/kg across 6 dated product listings
Identity & Market
Base polymer / chemistryPolyethylene — the simplest polyolefin, non-polar and highly crystalline. The one retailed filament grade, Spectrum HDPE, uses what Spectrum calls Low Warp technology and is denser and stiffer than plain HDPE[1][2]Polyetherimide, ULTEM 1010 grade — the higher-temperature, food- and medical-contact PEI[3][4]
Densityg/cm³1.10 (Spectrum HDPE filament, ISO 1183) against 0.95 for extruded HDPE stock — the filament is a modified formulation[1][2]1.27 (ISO 1183, 3DXTech and Prusament); 1.29 specific gravity on moulded plaques (ASTM D792, Stratasys)[3][4][5]
Typical priceUSD/kg1 kg-equivalent spools cluster near 88[6]1 kg-equivalent spools span 195–698; the middle of the market is about 270[7][8][9][10][11]
Price range across brandsUSD/kg87.72 — Spectrum's 500 g spools at 3DJAKE are the only PE filament listing found[6]195-698 across brands and grades; 3DXTech ThermaX PEI 1010 195 at 2 kg, IEMAI 3D 223 at 1 kg, 3D4Makers 270 at 2 kg, Prusament 292 at 500 g, Kimya 347 at 500 g, 3DXTech ESD-PEI 1010 698 at 500 g[7][8][9][10][11]
Market availability1–5Niche, a handful of specialist brands — Spectrum HDPE in six colours is the only PE filament in the 3DJAKE and igo3d product sitemaps, at MatterHackers or at Printed Solid, but it is a normal stocked item rather than a special order[12][13][14][6]Niche, a handful of specialist brands[7][8][9][10]
Spool sizes & diameters1.75 mm; 500 g spools in six colours[6][12]1.75 and 2.85 mm; 200 g to 2 kg spools, plus Stratasys canisters[7][10][5]
Typical applicationsChemically resistant containers, packaging prototypes and consumer goods where HDPE is the production material[1]Autoclavable tooling, food-contact fixtures and parts that must hold load near 200 °C[4]
Printing Parameters
Nozzle temperature°C240-290 (Spectrum HDPE)[1]410 ± 10 (Prusament) — the hottest nozzle in the dataset[4]
Bed temperature°C80-100 (Spectrum HDPE)[1]140–160 (Prusament); 130–140 (3DXTech)[4][3]
Enclosure / chamber requirement1–5Enclosure recommended — Spectrum recommends a closed chamber for larger prints[1]Actively heated chamber required — Prusa specifies 90 °C[4]
Recommended chamber temperature°CNot documented90 (Prusament)[4]
Part cooling fan0-50 % part cooling (Spectrum HDPE)[1]Not documented
Bed surface & adhesion aidSpectrum states no adhesive is necessary for its low-warp HDPE, depending on geometry[1]PA nylon sheet or powder-coated sheet with high-temperature glue (Prusament)[4]
Warping tendency1–5Moderate — needs adhesion aid or draught shield. Spectrum's low-warp grade is sold as printable on desktop machines, which is not true of plain polyethylene[1]Severe — heated chamber needed[4]
Bed-adhesion difficulty1–5Needs the right surface or a thin adhesive; Spectrum states no adhesive is necessary but recommends a closed chamber for large parts[1]Not documented
Overall printing difficulty1–5Intermediate — dry filament and a tuned profile; Spectrum sells the grade as desktop-printable with no dry box and no hardened nozzle[1]Expert / industrial hardware only[4][15]
Extruder requirementNot documentedA hot end rated to 420 °C, a heated chamber and a high-temperature bed; Prusa dries the filament at 150 °C for 6–8 h before printing[4]
Hardware Wear & Reliability
Nozzle hardness required1–4Brass fine indefinitely — Spectrum states a ruby or hardened nozzle is not required[1]Brass fine indefinitely for unfilled grades, but brass softens near these nozzle temperatures — hardened or plated hot ends are the norm[4]
Abrasiveness1–5Non-abrasive[1]Non-abrasive when unfilled[3]
Nozzle clog risk1–5Low — Spectrum lists no drybox and no ruby or hardened nozzle for HDPE, and very low moisture absorption[1]Moderate — needs dry filament and a clean nozzle; 3DXTech lists no special nozzle concerns but a mandatory 150 °C pre-dry before every print[16]
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5Negligible (<0.1 % EMC) — Spectrum lists very low moisture absorption and no dry box[1]Not documented
Equilibrium moisture content at ~50 % RH%Not documented0.4 in 24 h and 0.7 in 7 days at 24 °C and 22 % RH (Prusament)[4]
Drying temperature & timeNo drying step published; Spectrum lists a dry box as not required[1]150 °C for 6–8 h (Prusament) — the hottest drying schedule in the dataset[4]
Effect of moisture on strengthNot applicable in practice — Spectrum lists very low moisture absorption and no drybox requirement for HDPE[1]No dry-versus-conditioned figures are published; 3DXTech mandates a 150 °C, 4 h pre-dry before every print because trapped water flashes to steam at these nozzle temperatures[16]
Storage requirementStore dry at 18-25 °C out of sunlight; Spectrum quotes a 24-month shelf life[1]Not documented

Brittleness1–5Tough — absorbs impact, yields before breaking; 18 % elongation at break on the filament and above 100 % on extruded stock[1][2]Brittle — snaps with little warning; notched Charpy only 3.4 kJ/m²[4]
Hardness (scale-specific)Shore A / Shore D / RockwellShore D 67 and Rockwell R54 on extruded HDPE stock (ASTM D2240, D785); Spectrum quotes Rockwell 80 HRM for its filament (ISO 2039-2)[2][1]Shore D 83.5 (Prusa Polymers method); Rockwell M110 / R126 on extruded PEI stock (ASTM D785)[4][17]

Fatigue / repeated-flex resistance1–5Good — Spectrum lists outstanding abrasion and crack resistance for its HDPE, but no repeated-flex or fatigue test data was found for any PE filament[1]Not documented
Elasticity / flexibility1–5Slightly flexible in thin sections — Spectrum's low-warp grade has a 3.5 GPa tensile modulus; plain extruded HDPE at 965 MPa is genuinely semi-flexible[1][2]Rigid[4]

Flammability / UL 94Not documentedUL 94 V-0 at 1.5 mm, rated on the base resin[3]
Environment & Chemical
UV resistance1–5Moderate — a season or two. Spectrum describes its HDPE as UV-stable and weather-resistant but publishes no exposure data[1]Not documented
Chemical resistanceExcellent chemical resistance to acids, bases, oils and solvents (Spectrum); Ensinger lists broad chemical compatibility for HDPE stock[1][2]Not documented
Water / humidity resistance in service1–5Excellent — essentially unaffected; Ensinger lists low moisture absorption for HDPE stock and Spectrum very low absorption for the filament[1][2]Not documented
RecyclabilitySpectrum states the filament is fully recyclable; HDPE is resin code 2[1]Not documented
Health & Safety
Fume toxicity1–5Not documentedModerate — measurable VOCs and UFPs, ventilation advised. None of these polymers was in the chamber study, and all are processed far above the temperatures it covered[18]
Ventilation / filtration requirement1–5Not documentedVentilated room or enclosure recommended[18]
Post-Processing
Sanding & machiningEasy to machine — Ensinger lists machinability as a headline property of HDPE stock[2]Not documented
Dimensional accuracy & detailSpectrum lists a shiny surface finish and no adhesive requirement; shrinkage remains the limit on large flat parts[1]Not documented
Solvents & Solubility
Soluble inNone at room temperature; xylene dissolves HDPE at about 105 °C and LDPE at 75 °C. Hot decalin does the same.[19][20]Chlorinated hydrocarbons — dichloromethane and chloroform — are solvents for polyetherimide. Laboratory reagents.[21][22]
Softened or crazed byToluene, xylene, styrene, chloroform, dichloromethane, MEK and trichloroethylene are all unsatisfactory at 21 °C.[20]Acetone, MEK, benzene, toluene and butyl acetate craze or stress-crack it; alcohols, fuels and dilute acids do not.[22][21]
Solvent welding & smoothing agentNone — polyethylene has no room-temperature solvent, so joints are made by heat welding.[20][19]Dichloromethane is the only welding route, and it is a controlled carcinogen rather than a workshop material.[21][22]
