Identity & Market
Base polymer / chemistryPolyetherimide, ULTEM 1010 grade — the higher-temperature, food- and medical-contact PEI[1][2]PLA compounded with a mineral filler — Fiberlogy names chalk — that scatters light into a diffuse finish[3][4]
Densityg/cm³1.27 (ISO 1183, 3DXTech and Prusament); 1.29 specific gravity on moulded plaques (ASTM D792, Stratasys)[1][2][5]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 span 195–698; the middle of the market is about 270[6][7][8][9][10]Mainstream 1 kg spools cluster near 21[11][12][13]
Price range across brandsUSD/kg195-698 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[6][7][8][9][10]11–32 across brands; budget house brands 11–19, Fiberlogy PLA Mineral 32[14][12][15]
Market availability1–5Niche, a handful of specialist brands[6][7][8][9]Stocked by most mainstream brands[14][13][11]
Spool sizes & diameters1.75 and 2.85 mm; 200 g to 2 kg spools, plus Stratasys canisters[6][9][5]1.75 mm; 1 kg spools plus spool-less refills[11][16]
Typical applicationsAutoclavable tooling, food-contact fixtures and parts that must hold load near 200 °C[2]Display models and visible parts where a matte, non-reflective finish matters[4]
Diameter tolerance± mmNot documented±0.03 (Bambu Lab)[17]
Printing Parameters
Nozzle temperature°C410 ± 10 (Prusament) — the hottest nozzle in the dataset[2]190–230 (Bambu Lab); 190–210 (Fiberlogy PLA Mineral)[4][3]
Bed temperature°C140–160 (Prusament); 130–140 (3DXTech)[2][1]35–45 (Bambu Lab); 60 (Fiberlogy)[4][3]
Enclosure / chamber requirement1–5Actively heated chamber required — Prusa specifies 90 °C[2]Open frame is fine[4][3]
Recommended chamber temperature°C90 (Prusament)[2]Not documented
Part cooling fanNot documentedFan on; Fiberlogy specifies 75–100 %[4][3]
Bed surface & adhesion aidPA nylon sheet or powder-coated sheet with high-temperature glue (Prusament)[2]Cool plate, high-temperature plate or textured PEI with glue (Bambu Lab); smooth PEI, textured PEI or glass (Fiberlogy)[4][3]
Warping tendency1–5Severe — heated chamber needed[2]None[4]
Bed-adhesion difficulty1–5Not documentedSticks to anything[18]
Overall printing difficulty1–5Expert / industrial hardware only[2][19]Beginner — prints on any machine out of the box[4][3]
Extruder requirementA 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[2]Not documented
Hardware Wear & Reliability
Nozzle hardness required1–4Brass fine indefinitely for unfilled grades, but brass softens near these nozzle temperatures — hardened or plated hot ends are the norm[2]Brass fine indefinitely[20][4][3]
Abrasiveness1–5Non-abrasive when unfilled[1]Slightly abrasive — mineral filler pushes density from 1.24 to 1.31–1.38[3][4][21]
Nozzle clog risk1–5Moderate — needs dry filament and a clean nozzle; 3DXTech lists no special nozzle concerns but a mandatory 150 °C pre-dry before every print[22]Very low[20]
Heat-creep / jam sensitivity1–5Not documentedModerate — good heatbreak cooling needed; PLA softens below 60 °C[23]
Hotend requirementNot documentedNo special hot-end required[18]
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5Not documentedModerate — 0.40 % saturated at 25 °C / 55 % RH[4]
Equilibrium moisture content at ~50 % RH%0.4 in 24 h and 0.7 in 7 days at 24 °C and 22 % RH (Prusament)[2]0.40 saturated at 25 °C / 55 % RH (Bambu Lab)[4]
Drying temperature & time150 °C for 6–8 h (Prusament) — the hottest drying schedule in the dataset[2]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][24]
Symptoms when wetNot documentedBubbling and popping at the nozzle, stringing, rough surface and weak layers[25]
Effect of moisture on strengthNo 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[22]Polymaker rates PLA low-sensitivity — the loss shows as poor layer adhesion and brittle layers rather than a published strength figure[25]
Storage requirementNot documentedSealed with desiccant below 20 % RH; shelf life at ambient is long[21][18]

Environment & Chemical
UV resistance1–5Not documentedDegrades within weeks outdoors[23][30]
Chemical resistanceNot documentedGood against weak acids, oils and grease; poor against strong acids and alkalis; dissolved by chloroform, THF and hot benzene[29][23]
Water / humidity resistance in service1–5Not documentedGood — insoluble in water[21]
Food contactNot documentedBase resin is food-contact grade, but printed layer grooves harbour bacteria; Prusa advises against food use[23]
Biodegradability / compostabilityNot documentedIndustrially compostable only — needs sustained 55 °C; not home compostable[31][23]
RecyclabilityNot documentedMechanically recyclable; not accepted in household plastic collection[31]
Health & Safety
Fume toxicity1–5Moderate — 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[32]Low hazard — minimal VOC and particle emission[32]
Ventilation / filtration requirement1–5Ventilated room or enclosure recommended[32]None needed in a normal room[32]
Post-Processing
Sanding & machiningNot documentedWet sanding — dry sanding heats the surface by friction and smears it[30][23]
Gluing & solvent weldingNot documentedCyanoacrylate for most joints; some grades partially dissolve and bond with acetone[23][33]
Vapour / chemical smoothingNot documentedNo practical vapour smoothing — only chloroform, hot benzene or THF, which are laboratory-only[23]
Support material pairingNot documentedSupport for PLA (Bambu Lab)[4]
Dimensional accuracy & detailNot documentedMatte surface hides layer lines; 55° overhangs and 30 mm bridges as for plain PLA[4]
Solvents & Solubility
Soluble inChlorinated hydrocarbons — dichloromethane and chloroform — are solvents for polyetherimide. Laboratory reagents.[34][35]Chloroform: 10 % w/v in 2–4 h at 23 °C, every grade and morphology; THF and DMF only at 65 °C. Laboratory reagents.[36]
Softened or crazed byAcetone, MEK, benzene, toluene and butyl acetate craze or stress-crack it; alcohols, fuels and dilute acids do not.[35][34]Acetone, ethyl acetate and toluene plasticise it but dissolve <1 % even at 65 °C; submersion in acetone crazes and destroys parts.[36][37]
Solvent welding & smoothing agentDichloromethane is the only welding route, and it is a controlled carcinogen rather than a workshop material.[34][35]Chloroform vapour smooths and welds PLA at the cost of tensile strength; acetone does not smooth it at all.[38][37]
