Identity & Market
Base polymer / chemistryPETG compounded with a conductive filler to bring surface resistivity into the static-dissipative range[1][2]Polypropylene — a semi-crystalline polyolefin with no polar groups, so it neither absorbs water nor bonds to most bed surfaces[3][4]
Densityg/cm³1.24 (Fiberon) and 1.28 (3DXTech), ISO 1183[1][2]0.91 (Prusa PP composite, ISO 1183) — the lightest common filament[5]
Typical priceUSD/kg1 kg-equivalent spools span 66–140; the middle of the market is about 103[6][7]1 kg-equivalent spools span 27–53; the middle of the market is about 44[8][9][10][11]
Price range across brandsUSD/kg66–140 across brands; Fiberon PETG-ESD 66, 3DXSTAT ESD-PETG 140[6][7]27–53 across brands; Reli3D 32 on Amazon, SUNLU 44 at 0.8 kg, Fiberlogy 49 at 750 g, IEMAI 3D 53, and the 3DJake PP listing spans 27–49[8][12][9][10][11]
Market availability1–5Niche, a handful of specialist brands[6][7]Available from several mainstream brands[12][9][8]
Spool sizes & diameters1.75 mm; 0.5, 0.75, 1 and 3 kg spools[6][7]1.75 and 2.85 mm; 0.75 kg spools are common[9]
Typical applicationsElectronics fixtures, trays and jigs handled around static-sensitive components[1][2]Living hinges, chemical-resistant containers, automotive clips and packaging prototypes[3]
Printing Parameters
Nozzle temperature°C250–290 (Fiberon)[1]210–230 (Braskem-type PE/PP window); Formfutura's Centaur PP melts at 205 ± 15 °C[3]
Bed temperature°C70–80 (Fiberon); 70 (3DXTech)[1][2]Not documented
Enclosure / chamber requirement1–5Open frame is fine — Fiberon specifies room-temperature chamber[1]Enclosure recommended — Simplify3D lists an enclosure as a hardware requirement and Polymaker advises one below 70 °C ambient to stop warping and cracking[13][4]
Part cooling fanNot documentedPart cooling fan required (Simplify3D)[13]
Bed surface & adhesion aidTextured PEI, satin or powder-coated sheets; on smooth PEI a glue stick acts as a release agent[14][15]Packing tape, a polypropylene sheet, or a PP-specific adhesive such as Magigoo PP — ordinary PLA and ABS adhesives do not hold it[13][4]
Maximum volumetric flow (mm³/s; see test conditions)mm³/sFiberon rates the material to 500 mm/s, equivalent to 40 on a 0.4 mm nozzle at 0.2 mm layer — a machine-limited headline rather than a measured melt rate[1][16]Not documented
Warping tendency1–5Not documentedHigh — enclosure needed for reliable large parts; PP's crystallinity drives shrinkage and Prusa recommends a brim on its PP grades[5][17]
Bed-adhesion difficulty1–5Needs the right surface or a thin adhesive — the problem is releasing the part, not sticking it[14][15]Very difficult — special plates or slurry required. PP bonds to almost nothing; a polypropylene-specific tape or adhesive is the normal answer[5][4]
Stringing / oozing tendency1–5Moderate — retraction tuning needed; Polymaker names stringing as PETG's common quirk[15]Slight — Polymaker advises 1–2 mm retraction at 20–30 mm/s[4]
Overall printing difficulty1–5Intermediate — dry filament and a tuned profile; resistivity depends on getting the nozzle temperature right[1]Advanced — enclosure, hardware upgrades, tuning; bed adhesion is the whole problem[4][5]
Hardware Wear & Reliability
Nozzle hardness required1–4Hardened steel required[1]Brass fine indefinitely for unfilled grades — Simplify3D states no special hotend is required[13]
Abrasiveness1–5Moderately abrasive — conductive carbon filler[1]Non-abrasive when unfilled[13]
Nozzle clog risk1–5Low — 3DXTech lists no special nozzle concerns and no minimum layer height for its ESD-PETG, only a 65 °C pre-dry[18]Low — Simplify3D lists no special hotend requirement for PP and clogging is not among its listed drawbacks[19][13]
Heat-creep / jam sensitivity1–5Slightly sensitive[20]Slightly sensitive[13]
Hotend requirementNo special hot-end required[20]No special hot-end required (Simplify3D)[13]
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5Moderate (0.3–0.8 %) — the PETG matrix reaches 0.40 % saturated at 25 °C / 55 % RH and 3DXTech specifies a 65 °C, 4 h pre-dry[14][18]Negligible (<0.1 % EMC) — Prusa measures 0.03 % in 24 h and 0.04 % in 7 days on its PP composite, the lowest figures it publishes for any filament[5]
Equilibrium moisture content at ~50 % RH%0.41 equilibrium water absorption (Fiberon PETG-ESD)[1]0.03 after 24 h and 0.04 after 7 days at 24 °C / 22 % RH (Prusa Polymers, measured on its PP composite)[5]
Drying temperature & time65 °C for 3 h (Fiberon)[1]No drying step is published for PP; uptake is below the level that affects printing[5]
Symptoms when wetBubbling and popping at the nozzle, stringing and a rough surface[19]Bubbling and popping at the nozzle; Polymaker still advises a 70 °C dry for 4–6 h despite the low uptake[4]
Effect of moisture on strengthPolymaker groups PETG with nylon, PVA and TPU as highly hygroscopic; no dry-versus-conditioned strength figures are published for this grade and the loss shows as bubbling and poor layer adhesion[19]Not applicable in practice — with equilibrium uptake at 0.04 %, there is no moisture-driven strength loss to measure. Polymaker's sensitivity tiers put polyolefins below even PLA[5][19]
Storage requirementSealed with desiccant; Polymaker groups PETG with the highly hygroscopic materials[19][15]No special storage needed[5]
Mechanical Properties

Fatigue / repeated-flex resistance1–5Moderate — no ESD-grade S-N curve; unfilled printed PETG ran 79 000–193 000 cycles at 30 % of tensile strength[26]Excellent — living hinges viable, the classic polypropylene application[3]
Elasticity / flexibility1–5Slightly flexible in thin sections[1]Semi-flexible[3]
Z strength as % of XY%57 (Fiberon, printed Z against XY tensile)[1]Not documented

HDT at 1.8 MPa°C72 (ISO 75, 1.8 MPa, Fiberon)[1]Not documented
Glass transition (Tg)°C77 (Fiberon) and 80 (3DXTech), DSC[1][2]Not documented
Melting point / Vicat°CAmorphous — no melting point; Vicat 86 (Fiberon, ISO 306)[1]205 ± 15 melting (Formfutura Centaur PP)[3]
Continuous service temperature°CNot documentedBounded by a melting point of 205 ± 15 °C and by the 158 °C heat deflection of the carbon-filled grade; no loaded-bar service figure is published for unfilled PP[3][5]
Flammability / UL 94Flammable; no UL 94 rating published for standard grades[27]Flammable; no UL 94 rating published for the grades surveyed[5]
Environment & Chemical
UV resistance1–5Not documentedMonths outdoors before embrittlement — unstabilised polypropylene chalks under UV[4]
Chemical resistanceWithstands acids, alkalis, oils and UV exposure[15]Excellent against acids, alkalis and most solvents — the usual reason to choose PP[4]
Water / humidity resistance in service1–5Not documentedExcellent — essentially unaffected[5]
Food contactNot certified for food contact as filament[15]Polypropylene is a common food-packaging polymer, but no filament here carries a food-contact certification[4]
Biodegradability / compostabilityNot biodegradable[15]Not biodegradable[4]
RecyclabilityNot accepted in household plastic collection[15]Mechanically recyclable as resin code 5, but printed waste is not accepted in household collection[4]
Electrical & ESD propertiesSurface resistivity falls with nozzle temperature: 7.0×10⁶–1.6×10⁷ ohm at 250 °C, 3.2×10⁵–4.7×10⁵ at 270 °C and below 1×10⁴ at 290 °C (Fiberon); 3DXTech quotes 10⁷–10⁹ ohm/sq[1][2]Not documented
Health & Safety
Fume toxicity1–5Moderate — measurable VOCs and UFPs, ventilation advised[28]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[28]
Ventilation / filtration requirement1–5Open a window / occasional ventilation[28]Open a window / occasional ventilation. Inferred — no polyolefin was measured in the chamber study[28]
Dust & fibre handling hazardConductive carbon filler is bound in the matrix; avoid inhaling sanding dust[1]Not documented
Post-Processing
Sanding & machiningSands poorly — the material is tough and gums rather than powders[20]Sands poorly — the waxy surface loads abrasive paper[13]
Painting & finishingNot documentedPaint and adhesives do not key to untreated PP; flame or plasma treatment is normally needed first[4]
Gluing & solvent weldingCyanoacrylate; no common solvent welds PETG cleanly[20]Nothing common bonds untreated PP; flame or plasma treatment is needed before adhesives key[4]
Vapour / chemical smoothingNo practical vapour smoothing[20]No practical vapour smoothing[13]
Support material pairingPrints its own supports; Polymaker rates PolyDissolve S1 for PETG[20]Prints its own supports; no soluble support is rated for PP[13]
Dimensional accuracy & detailNozzle temperature has to be held steady — it moves surface resistivity by three orders of magnitude[1]Shrinkage and warping dominate; the low modulus means parts flex rather than hold tolerance[5]
Solvents & Solubility
Soluble inNo common workshop solvent; 1,2-dichloroethane destroys it inside a week and dichloromethane — a carcinogen — dissolves the surface.[29][30]None at room temperature; chloroform dissolves it at 60 °C and xylene at about 118 °C — the xylene-solubles route.[31][32]
Softened or crazed byAcetone (+16 % weight over 1 year at 23 °C), ethyl acetate, toluene and DMF swell and soften it; methanol crazes it.[29]Xylene, decalin, CCl4 and chlorobenzene are heavily absorbed at 20 °C; oleum, chlorosulphonic acid and bromine destroy it.[31]
Solvent welding & smoothing agentDichloromethane brushed on is the only agent that smooths PETG — a controlled carcinogen, not workshop stock.[30]None — nothing softens PP at room temperature, so joints have to be welded thermally rather than chemically.[31]
