Identity & Market
Base polymer / chemistryAcrylonitrile butadiene styrene — a styrenic terpolymer with a butadiene rubber phase[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/cm³1.04 (Polymaker PolyLite ABS and ABS Pro) to 1.06 (ABS Max), ISO 1183; Bambu Lab 1.05[5][1][6][7]0.91 (Prusa PP composite, ISO 1183) — the lightest common filament[8]
Typical priceUSD/kg1 kg spools cluster near 20[9][10][11][12][13]1 kg-equivalent spools span 27–53; the middle of the market is about 44[14][15][16][17]
Price range across brandsUSD/kg12–45 across brands; IEMAI 12, SUNLU 12 at a 3 kg minimum, ELEGOO 15 in a 5 kg pack, Polymaker 19, YXPOLYER 20, Bambu Lab 20, Push Plastic 25, 3DXTech 45[9][10][18][19][11][12][13][20]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[14][21][15][16][17]
Market availability1–5Ubiquitous, every brand and retailer[9][10][18][19]Available from several mainstream brands[21][15][14]
Spool sizes & diameters1.75 and 2.85 mm; 1, 5 and 10 kg spools[18][19]1.75 and 2.85 mm; 0.75 kg spools are common[15]
Typical applicationsEnclosures, automotive interior parts and tooling that must hold shape above PLA's 55 °C ceiling[1][22]Living hinges, chemical-resistant containers, automotive clips and packaging prototypes[3]
Printing Parameters
Nozzle temperature°C240–270 (Bambu Lab); 245–265 (Polymaker PolyLite)[5][1]210–230 (Braskem-type PE/PP window); Formfutura's Centaur PP melts at 205 ± 15 °C[3]
Bed temperature°C80–100 (Bambu Lab); 90–100 (Polymaker)[5][1]Not documented
Enclosure / chamber requirement1–5Enclosure recommended — Polymaker calls a chamber needed at ambient temperature, Bambu Lab requires an enclosed printer and rules out its P1P and A-series machines[1][23]Enclosure recommended — Simplify3D lists an enclosure as a hardware requirement and Polymaker advises one below 70 °C ambient to stop warping and cracking[24][4]
Recommended chamber temperature°C45–60 (Bambu Lab)[5]Not documented
Part cooling fan0–80 % (Bambu Lab); off (Polymaker PolyLite)[5][1]Part cooling fan required (Simplify3D)[24]
Bed surface & adhesion aidClean the plate and apply glue — Bambu Lab lists glue as the way to improve adhesion and prevent warping[23]Packing tape, a polypropylene sheet, or a PP-specific adhesive such as Magigoo PP — ordinary PLA and ABS adhesives do not hold it[24][4]
Maximum volumetric flow (mm³/s; see test conditions)mm³/s10–16 (PrusaSlicer guidance for ABS/ASA)[25]Not documented
Warping tendency1–5High — enclosure needed for reliable large parts; Bambu Lab attributes surface cracking to cooling stress exceeding interlayer adhesion[23]High — enclosure needed for reliable large parts; PP's crystallinity drives shrinkage and Prusa recommends a brim on its PP grades[8][26]
Bed-adhesion difficulty1–5Needs a specific surface plus adhesive[23]Very difficult — special plates or slurry required. PP bonds to almost nothing; a polypropylene-specific tape or adhesive is the normal answer[8][4]
Stringing / oozing tendency1–5Slight[1]Slight — Polymaker advises 1–2 mm retraction at 20–30 mm/s[4]
Overall printing difficulty1–5Intermediate — dry filament and a tuned profile[23][1]Advanced — enclosure, hardware upgrades, tuning; bed adhesion is the whole problem[4][8]
Hardware Wear & Reliability
Nozzle hardness required1–4Brass fine indefinitely[23]Brass fine indefinitely for unfilled grades — Simplify3D states no special hotend is required[24]
Abrasiveness1–5Non-abrasive[23]Non-abrasive when unfilled[24]
Nozzle clog risk1–5Low — no special hot-end required and clogging is not among the listed drawbacks; Prusa lists no drybox and no hardened nozzle[27][28]Low — Simplify3D lists no special hotend requirement for PP and clogging is not among its listed drawbacks[29][24]
Heat-creep / jam sensitivity1–5Slightly sensitive[27]Slightly sensitive[24]
Hotend requirementNo special hot-end required[27]No special hot-end required (Simplify3D)[24]
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5Moderate — 0.65 % saturated at 25 °C / 55 % RH (Bambu Lab); Polymaker measures 0.51 % maximum uptake for ABS Pro[5][6]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[8]
Equilibrium moisture content at ~50 % RH%0.65 saturated at 25 °C / 55 % RH (Bambu Lab); 0.51 maximum (Polymaker ABS Pro)[5][6]0.03 after 24 h and 0.04 after 7 days at 24 °C / 22 % RH (Prusa Polymers, measured on its PP composite)[8]
Drying temperature & time80 °C for 8 h (Bambu Lab); 70 °C for 6 h (Polymaker)[5][1]No drying step is published for PP; uptake is below the level that affects printing[8]
Symptoms when wetBubbling and popping at the nozzle, stringing, rough surface and weak layers[29]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 rates ABS moderate-sensitivity and publishes no dry-versus-conditioned figures; the loss appears as poor layer adhesion and surface defects rather than a stated strength delta[29]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[8][29]
Storage requirementSealed with desiccant; Polymaker rates ABS moderate-sensitivity and advises periodic drying in humid climates[29]No special storage needed[8]
Mechanical Properties
Tensile strength (XY)MPa33 ± 3 (Bambu Lab) to 35 (Polymaker ABS Pro and Max) printed XY, ISO 527; 3DXTech quotes 42 at break[5][6][7][30]12 at yield (Formfutura Centaur PP, ASTM D638)[3]

Hardness (scale-specific)Shore A / Shore D / RockwellNot documentedRockwell R102 (and M95) on extruded PP stock (ASTM D785)[31]
Creep resistance / sustained load1–5Moderate — no printed-ABS creep test found; Tg of 101–126 °C keeps room-temperature service far below softening, unlike PLA[1][6][7]Below average[3]
Fatigue / repeated-flex resistance1–5Moderate — no printed-ABS S-N curve found; 10.5 % elongation and 21.5 kJ/m² notched Charpy give far more cyclic tolerance than PLA[5][32]Excellent — living hinges viable, the classic polypropylene application[3]
Elasticity / flexibility1–5Rigid[5]Semi-flexible[3]
Z strength as % of XY%85 (Bambu Lab, printed Z against XY tensile); 63 for Polymaker ABS Pro[5][6]Not documented

Annealing responseDecomposition above 380 °C (PolyLite ABS, TGA)[1]Not documented
Thermal expansion (CTE)µm/m·K86 ± 3 at 0° and 89 ± 3 at 90° raster (printed, fibre Bragg grating, 25–50 °C); 82 for a neat large-format bead at 30 °C[34][35]Not documented
Flammability / UL 94Flammable; no UL 94 rating published for standard ABS, though V-0 grades exist[36][5]Flammable; no UL 94 rating published for the grades surveyed[8]
Environment & Chemical
UV resistance1–5Months outdoors before embrittlement[22]Months outdoors before embrittlement — unstabilised polypropylene chalks under UV[4]
Chemical resistanceGood against weak acids, weak alkalis, oils and grease; poor against strong acids; dissolved by acetone[1]Excellent against acids, alkalis and most solvents — the usual reason to choose PP[4]
Water / humidity resistance in service1–5Good — minor absorption[5]Excellent — essentially unaffected[8]
Food contactNot food safe — Polymaker cites potential chemical leaching[22]Polypropylene is a common food-packaging polymer, but no filament here carries a food-contact certification[4]

RecyclabilityMechanically recyclable as resin code 9, but not accepted in household plastic collection[22]Mechanically recyclable as resin code 5, but printed waste is not accepted in household collection[4]
Electrical & ESD propertiesSurface resistance above 10¹³ ohm/sq — insulating (3DXTech, ASTM D257)[30]Not documented
Health & Safety
Fume toxicity1–5High — hazardous VOC such as styrene; enclosure and filtration needed[37][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[37]
VOC emission rateµg/min12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[37]Not documented
Ultrafine-particle emission rateparticles/min2 × 10¹⁰ to 9 × 10¹⁰ median across all ABS printers, two orders of magnitude above PLA's ≈1 × 10⁸[37]Not documented
Hazardous species emittedStyrene dominates. Bambu Lab states ABS and ASA release harmful gases such as styrene at printing temperature, which can be toxic and cause dizziness or nausea[37][23]Not documented
Ventilation / filtration requirement1–5Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[37][23]Open a window / occasional ventilation. Inferred — no polyolefin was measured in the chamber study[37]
Post-Processing
Sanding & machiningSands well and takes filler; the usual preparation before painting[22]Sands poorly — the waxy surface loads abrasive paper[24]
Painting & finishingNot documentedPaint and adhesives do not key to untreated PP; flame or plasma treatment is normally needed first[4]
Gluing & solvent weldingSolvent-welds with acetone[1]Nothing common bonds untreated PP; flame or plasma treatment is needed before adhesives key[4]
Vapour / chemical smoothingAcetone vapour smoothing works — ABS dissolves in acetone[1]No practical vapour smoothing[24]
Support material pairingHIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[38][23]Prints its own supports; no soluble support is rated for PP[24]
Dimensional accuracy & detailWarping and cooling-stress cracking are the accuracy limits, not shrinkage of the melt[23]Shrinkage and warping dominate; the low modulus means parts flex rather than hold tolerance[8]
Solvents & Solubility
Soluble inAcetone dissolves it — the basis of ABS slurry; so do MEK, THF, ethyl acetate, chloroform, dichloromethane and toluene.[39][1]None at room temperature; chloroform dissolves it at 60 °C and xylene at about 118 °C — the xylene-solubles route.[40][41]
Softened or crazed byPetrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[39][42]Xylene, decalin, CCl4 and chlorobenzene are heavily absorbed at 20 °C; oleum, chlorosulphonic acid and bromine destroy it.[40]
Solvent welding & smoothing agentAcetone: about 20 min of vapour at 80 °C over 5 mm of liquid. Prusa measured layer adhesion more than doubled.[43]None — nothing softens PP at room temperature, so joints have to be welded thermally rather than chemically.[40]
