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]PLA compounded with a mineral filler — Fiberlogy names chalk — that scatters light into a diffuse finish[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]1.31 (Bambu Lab, ISO 1183) to 1.38 (Fiberlogy PLA Mineral, method not stated) — above plain PLA from the filler[4][3]
Typical priceUSD/kg1 kg-equivalent spools cluster near 88[5]Mainstream 1 kg spools cluster near 21[6][7][8]
Price range across brandsUSD/kg87.72 — Spectrum's 500 g spools at 3DJAKE are the only PE filament listing found[5]11–32 across brands; budget house brands 11–19, Fiberlogy PLA Mineral 32[9][7][10]
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[11][12][13][5]Stocked by most mainstream brands[9][8][6]
Spool sizes & diameters1.75 mm; 500 g spools in six colours[5][11]1.75 mm; 1 kg spools plus spool-less refills[6][14]
Typical applicationsChemically resistant containers, packaging prototypes and consumer goods where HDPE is the production material[1]Display models and visible parts where a matte, non-reflective finish matters[4]
Diameter tolerance± mmNot documented±0.03 (Bambu Lab)[15]
Printing Parameters
Nozzle temperature°C240-290 (Spectrum HDPE)[1]190–230 (Bambu Lab); 190–210 (Fiberlogy PLA Mineral)[4][3]
Bed temperature°C80-100 (Spectrum HDPE)[1]35–45 (Bambu Lab); 60 (Fiberlogy)[4][3]
Enclosure / chamber requirement1–5Enclosure recommended — Spectrum recommends a closed chamber for larger prints[1]Open frame is fine[4][3]
Part cooling fan0-50 % part cooling (Spectrum HDPE)[1]Fan on; Fiberlogy specifies 75–100 %[4][3]
Bed surface & adhesion aidSpectrum states no adhesive is necessary for its low-warp HDPE, depending on geometry[1]Cool plate, high-temperature plate or textured PEI with glue (Bambu Lab); smooth PEI, textured PEI or glass (Fiberlogy)[4][3]
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]None[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]Sticks to anything[16]
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]Beginner — prints on any machine out of the box[4][3]
Hardware Wear & Reliability
Nozzle hardness required1–4Brass fine indefinitely — Spectrum states a ruby or hardened nozzle is not required[1]Brass fine indefinitely[17][4][3]
Abrasiveness1–5Non-abrasive[1]Slightly abrasive — mineral filler pushes density from 1.24 to 1.31–1.38[3][4][18]
Nozzle clog risk1–5Low — Spectrum lists no drybox and no ruby or hardened nozzle for HDPE, and very low moisture absorption[1]Very low[17]
Heat-creep / jam sensitivity1–5Not documentedModerate — good heatbreak cooling needed; PLA softens below 60 °C[19]
Hotend requirementNot documentedNo special hot-end required[16]
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5Negligible (<0.1 % EMC) — Spectrum lists very low moisture absorption and no dry box[1]Moderate — 0.40 % saturated at 25 °C / 55 % RH[4]
Equilibrium moisture content at ~50 % RH%Not documented0.40 saturated at 25 °C / 55 % RH (Bambu Lab)[4]
Drying temperature & timeNo drying step published; Spectrum lists a dry box as not required[1]50 °C for 8 h in a forced-air dryer, or 60–70 °C for 12 h on an X1 heatbed; Fiberlogy specifies 50 °C for 6 h[4][3][20]
Symptoms when wetNot documentedBubbling and popping at the nozzle, stringing, rough surface and weak layers[21]
Effect of moisture on strengthNot applicable in practice — Spectrum lists very low moisture absorption and no drybox requirement for HDPE[1]Polymaker rates PLA low-sensitivity — the loss shows as poor layer adhesion and brittle layers rather than a published strength figure[21]
Storage requirementStore dry at 18-25 °C out of sunlight; Spectrum quotes a 24-month shelf life[1]Sealed with desiccant below 20 % RH; shelf life at ambient is long[18][16]
Mechanical Properties
Tensile strength (XY)MPa29 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]30 (printed XY, ISO 527, Bambu Lab); 35.1 on My Tech Fun bars for PolyTerra PLA[4][22]
Young's modulusMPa3500 (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]1960 (Bambu Lab, printed XY, ISO 527); Fiberlogy PLA Mineral quotes 3500 (ISO 527, specimen type not stated)[4][3]
Elongation at break%18 at break (Spectrum HDPE, ISO 527) against above 100 on extruded stock (ASTM D638)[1][2]14.8 (printed XY, ISO 527)[4]
Flexural strengthMPa27.6 on extruded HDPE stock (ASTM D790; converted from 4000 psi)[2]53 (printed XY, ISO 178) — 30 % below PLA Basic at 76[4][18]
Flexural modulusMPa3200 (Spectrum HDPE, ISO 178) against 965 on extruded stock (ASTM D790, from 140,000 psi)[1][2]2360 (printed XY, ISO 178)[4]
Charpy impact, notchedkJ/m²Not documented6.3 (printed XY, ISO 179, notched); unnotched 19.2[4]
Other impact dataCharpy 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]Izod 6.1 kJ/m² on My Tech Fun printed bars for PolyTerra PLA[22]
Layer adhesion / Z tensileMPaNot documented22 (printed Z, ISO 527); flexural Z falls to 29 against 53 in XY; 12.9 on My Tech Fun layer-adhesion bars[4][22]
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[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]Not documented
Creep resistance / sustained load1–5Not documentedPoor — 12 mm bar sagged to 18.7 mm over 5 days at 1.25 kg[22]
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]Poor — no grade-specific S-N curve; plain printed PLA ran 38 000–49 000 cycles at 30 % of tensile strength (R = 0.2)[23][19]
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]
Z strength as % of XY%Not documented73 by tensile, 55 by flexural (printed, Bambu Lab)[4]
Thermal Properties
HDT at 0.45 MPa°C75 on extruded HDPE stock (ASTM D648 at 66 psi; converted from 167 °F)[2]58 (Bambu Lab) and 48 (Fiberlogy PLA Mineral), ISO 75 at 0.45 MPa[4][3]
HDT at 1.8 MPa°CNot documented52 (ISO 75, 1.8 MPa)[4]
Glass transition (Tg)°CNot documented61 (DSC)[4]
Melting point / Vicat°CNot documented163 peak melt (DSC); Vicat 63 °C[4]
Continuous service temperature°C110 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]54 — loaded bars begin to move at this temperature[22]
Annealing responseNot documented50–60 °C for 6–12 h; some prints deform or warp, and a forced-air oven is required[4]
Thermal expansion (CTE)µm/m·K117 (extruded HDPE stock, ASTM D696; source states 6.5e-5 in/in/°F)[2]Not documented
Flammability / UL 94Not documentedFlammable; no UL 94 rating published by the major brands[18][24]
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]Degrades within weeks outdoors[19][25]
Chemical resistanceExcellent chemical resistance to acids, bases, oils and solvents (Spectrum); Ensinger lists broad chemical compatibility for HDPE stock[1][2]Good against weak acids, oils and grease; poor against strong acids and alkalis; dissolved by chloroform, THF and hot benzene[24][19]
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]Good — insoluble in water[18]
Food contactNot documentedBase resin is food-contact grade, but printed layer grooves harbour bacteria; Prusa advises against food use[19]
Biodegradability / compostabilityNot documentedIndustrially compostable only — needs sustained 55 °C; not home compostable[26][19]
RecyclabilitySpectrum states the filament is fully recyclable; HDPE is resin code 2[1]Mechanically recyclable; not accepted in household plastic collection[26]
Health & Safety
Fume toxicity1–5Not documentedLow hazard — minimal VOC and particle emission[27]
Ventilation / filtration requirement1–5Not documentedNone needed in a normal room[27]
Post-Processing
Sanding & machiningEasy to machine — Ensinger lists machinability as a headline property of HDPE stock[2]Wet sanding — dry sanding heats the surface by friction and smears it[25][19]
Gluing & solvent weldingNot documentedCyanoacrylate for most joints; some grades partially dissolve and bond with acetone[19][28]
Vapour / chemical smoothingNot documentedNo practical vapour smoothing — only chloroform, hot benzene or THF, which are laboratory-only[19]
Support material pairingNot documentedSupport for PLA (Bambu Lab)[4]
Dimensional accuracy & detailSpectrum lists a shiny surface finish and no adhesive requirement; shrinkage remains the limit on large flat parts[1]Matte surface hides layer lines; 55° overhangs and 30 mm bridges as for plain PLA[4]
Solvents & Solubility
Soluble inNone at room temperature; xylene dissolves HDPE at about 105 °C and LDPE at 75 °C. Hot decalin does the same.[29][30]Chloroform: 10 % w/v in 2–4 h at 23 °C, every grade and morphology; THF and DMF only at 65 °C. Laboratory reagents.[31]
Softened or crazed byToluene, xylene, styrene, chloroform, dichloromethane, MEK and trichloroethylene are all unsatisfactory at 21 °C.[30]Acetone, ethyl acetate and toluene plasticise it but dissolve <1 % even at 65 °C; submersion in acetone crazes and destroys parts.[31][32]
Solvent welding & smoothing agentNone — polyethylene has no room-temperature solvent, so joints are made by heat welding.[30][29]Chloroform vapour smooths and welds PLA at the cost of tensile strength; acetone does not smooth it at all.[33][32]
