| Listing priceUSD/kg; dated snapshots | $87.72/kg median; $87.72–$87.72/kg across 1 dated product listings | $42.49/kg median; $26.00–$79.98/kg across 4 dated product listings |
| Identity & Market | ||
| Base polymer / chemistry | Polyethylene — 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] | Break-away support compounds matched to a specific model material — Polymaker sells separate grades for PLA and for PA12[3][4] |
| Densityg/cm³ | 1.10 (Spectrum HDPE filament, ISO 1183) against 0.95 for extruded HDPE stock — the filament is a modified formulation[1][2] | 1.22 (PolySupport for PLA) and 1.29 (PolySupport for PA12), ISO 1183[3][4] |
| Typical priceUSD/kg | 1 kg-equivalent spools cluster near 88[5] | 1 kg-equivalent spools span 26–80; the middle of the market is about 45[6][7][8] |
| Price range across brandsUSD/kg | 87.72 — Spectrum's 500 g spools at 3DJAKE are the only PE filament listing found[5] | 26–80 across brands and grades; IEMAI 3D E-REMOVE 26, Polymaker PolySupport for PLA 40 at 750 g, YXPOLYER 45, PolySupport for PA12 80 at 500 g[6][7][8] |
| Market availability1–5 | Niche, 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[9][10][11][5] | Available from several mainstream brands[6][12] |
| Spool sizes & diameters | 1.75 mm; 500 g spools in six colours[5][9] | 1.75 and 2.85 mm; 0.5 and 0.75 kg spools[6] |
| Typical applications | Chemically resistant containers, packaging prototypes and consumer goods where HDPE is the production material[1] | Support that peels off by hand, avoiding the moisture handling and dissolution time that soluble supports demand[3] |
| Printing Parameters | ||
| Nozzle temperature°C | 240-290 (Spectrum HDPE)[1] | 220–230 (PolySupport for PLA)[3] |
| Bed temperature°C | 80-100 (Spectrum HDPE)[1] | 25–60 (PolySupport for PLA)[3] |
| Enclosure / chamber requirement1–5 | Enclosure recommended — Spectrum recommends a closed chamber for larger prints[1] | Open frame is fine[3] |
| Part cooling fan | 0-50 % part cooling (Spectrum HDPE)[1] | Not documented |
| Bed surface & adhesion aid | Spectrum states no adhesive is necessary for its low-warp HDPE, depending on geometry[1] | Not documented |
| Maximum volumetric flow (mm³/s; see test conditions)mm³/s | Not documented | 4–12 at Polymaker's 50–150 mm/s on a 0.4 mm nozzle at 0.2 mm layer[3] |
| Warping tendency1–5 | Moderate — 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] | Not documented |
| Bed-adhesion difficulty1–5 | Needs 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 difficulty1–5 | Intermediate — dry filament and a tuned profile; Spectrum sells the grade as desktop-printable with no dry box and no hardened nozzle[1] | Easy — minor profile tuning[3] |
| Extruder requirement | Not documented | A second extruder or a tool changer[3] |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Brass fine indefinitely — Spectrum states a ruby or hardened nozzle is not required[1] | Brass fine indefinitely[3] |
| Abrasiveness1–5 | Non-abrasive[1] | Non-abrasive[3] |
| Nozzle clog risk1–5 | Low — 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; Polymaker specifies a 55 °C dry for the PLA grade and warns brass nozzle life falls to about 9 h on the PA12 grade[3][4] |
| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | Negligible (<0.1 % EMC) — Spectrum lists very low moisture absorption and no dry box[1] | Moderate — 0.64 % equilibrium water absorption (PolySupport for PLA)[3] |
| Equilibrium moisture content at ~50 % RH% | Not documented | 0.64 equilibrium water absorption (Polymaker PolySupport for PLA)[3] |
| Drying temperature & time | No drying step published; Spectrum lists a dry box as not required[1] | Not documented |
| Effect of moisture on strength | Not applicable in practice — Spectrum lists very low moisture absorption and no drybox requirement for HDPE[1] | Not a structural material; no dry-versus-conditioned data is published[13] |
| Storage requirement | Store dry at 18-25 °C out of sunlight; Spectrum quotes a 24-month shelf life[1] | Not documented |
| Mechanical Properties | ||
| Tensile strength (XY)MPa | 29 at break (Spectrum HDPE, ISO 527; specimen type not stated) against 25.5 at yield on extruded HDPE stock (ASTM D638, from 3700 psi)[1][2] | Not documented |
| Young's modulusMPa | 3500 (Spectrum HDPE, ISO 527) against 965 on extruded HDPE stock (ASTM D638, from 140,000 psi) — the filament grade is nearly four times stiffer than plain polyethylene[1][2] | Not documented |
| Elongation at break% | 18 at break (Spectrum HDPE, ISO 527) against above 100 on extruded stock (ASTM D638)[1][2] | Not documented |
| Flexural strengthMPa | 27.6 on extruded HDPE stock (ASTM D790; converted from 4000 psi)[2] | Not documented |
| Flexural modulusMPa | 3200 (Spectrum HDPE, ISO 178) against 965 on extruded stock (ASTM D790, from 140,000 psi)[1][2] | Not documented |
| Other impact data | Charpy 10 kJ/m2 (Spectrum HDPE, ISO 179-1; notch condition not stated); Izod 104 J/m on extruded stock, converted from 1.94 ft-lb/in (ASTM D256)[1][2] | Not documented |
| Brittleness1–5 | Tough — absorbs impact, yields before breaking; 18 % elongation at break on the filament and above 100 % on extruded stock[1][2] | Not documented |
| Hardness (scale-specific)Shore A / Shore D / Rockwell | Shore 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] | Not documented |
| Fatigue / repeated-flex resistance1–5 | Good — 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 / flexibility1–5 | Slightly 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] | Not documented |
| Thermal Properties | ||
| HDT at 0.45 MPa°C | 75 on extruded HDPE stock (ASTM D648 at 66 psi; converted from 167 °F)[2] | 43 (ISO 75, 0.45 MPa, PolySupport for PA12). Polymaker's sheet prints a higher figure at the higher load, which is physically inverted; treat both HDT numbers as approximate[4] |
| HDT at 1.8 MPa°C | Not documented | 53 (ISO 75, 1.8 MPa, PolySupport for PA12) — printed above the 0.45 MPa figure on Polymaker's own sheet, which cannot be right; treat both as approximate[4] |
| Melting point / Vicat°C | Not documented | Vicat 171 (PolySupport for PA12, ISO 306)[4] |
| Continuous service temperature°C | 110 stated as heat resistance by Spectrum with no test standard given; extruded stock is rated 120 long-term maximum (converted from 248 °F) and brittle below -76[1][2] | Not documented |
| Thermal expansion (CTE)µm/m·K | 117 (extruded HDPE stock, ASTM D696; source states 6.5e-5 in/in/°F)[2] | Not documented |
| Environment & Chemical | ||
| UV resistance1–5 | Moderate — a season or two. Spectrum describes its HDPE as UV-stable and weather-resistant but publishes no exposure data[1] | Not documented |
| Chemical resistance | Excellent 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 service1–5 | Excellent — essentially unaffected; Ensinger lists low moisture absorption for HDPE stock and Spectrum very low absorption for the filament[1][2] | Not documented |
| Recyclability | Spectrum states the filament is fully recyclable; HDPE is resin code 2[1] | Not documented |
| Electrical & ESD properties | Not documented | Surface resistance above 10^13 ohm/sq (ASTM D257, THERMAX HTS2 and MTS1)[14][15] |
| Health & Safety | ||
| Fume toxicity1–5 | Not documented | Low hazard — minimal VOC and particle emission; none of these materials was in the chamber study[16] |
| Ventilation / filtration requirement1–5 | Not documented | Open a window / occasional ventilation[16] |
| Post-Processing | ||
| Sanding & machining | Easy to machine — Ensinger lists machinability as a headline property of HDPE stock[2] | Not documented |
| Support material pairing | Not documented | This is the support material. Polymaker publishes an adhesion matrix per model material, from very good to unusable, because break-away supports only work against the polymer they were matched to[3][4] |
| Dimensional accuracy & detail | Spectrum lists a shiny surface finish and no adhesive requirement; shrinkage remains the limit on large flat parts[1] | Not documented |
| Solvents & Solubility | ||
| Soluble in | None at room temperature; xylene dissolves HDPE at about 105 °C and LDPE at 75 °C. Hot decalin does the same.[17][18] | None — break-away support is removed mechanically; 3DXTech lists no water or solvent route for it.[19] |
| Softened or crazed by | Toluene, xylene, styrene, chloroform, dichloromethane, MEK and trichloroethylene are all unsatisfactory at 21 °C.[18] | Not documented |
| Solvent welding & smoothing agent | None — polyethylene has no room-temperature solvent, so joints are made by heat welding.[18][17] | None — there is no solvent to weld or smooth with.[19] |
