ULTEM 1010 overview
ULTEM 1010 is the most heat-resistant plastic for FDM 3D printing, for tools and parts that must stay strong when hot. Parts keep their shape in hot engine bays and autoclave cycles, resist fuels, coolants and many industrial chemicals, and are naturally flame retardant. The certified grade of Stratasys ULTEM 1010 is approved for food contact and meets medical biocompatibility standards, and surgical guides made from it can be steam sterilized. Aerospace, automotive, medical and food production teams use it for composite lay-up tools, under-hood ducts and housings, surgical guides, instrument trays and food-production fixtures. Triton PEI 1010 is 3DXTECH's ULTEM 1010 PEI for Stratasys printers, for high-heat tooling, fixtures and parts. Its 217 °C glass transition temperature keeps parts performing at elevated temperatures, and it combines exceptional dimensional stability with inherent flame retardancy and good chemical resistance.
Also available in Stratasys ULTEM 1010.
How ULTEM 1010 is manufactured
ULTEM 1010 is manufactured using Fused Deposition Modeling (FDM) on Stratasys Fortus production systems, which build parts layer by layer from PEI filament, with no tooling. Large build envelopes take full-size tools, ducts and fixtures in one piece. This makes ULTEM 1010 a practical route to autoclave-resistant medical instruments, composite tooling and food-production fixtures, in quantities from a single tool to low-volume production.

Industry applications
Industry applications for ULTEM 1010
ULTEM 1010 combines exceptional tensile strength along the layers with resistance to a wide range of fuels, coolants and industrial chemicals, and keeps its shape under load above 200 °C, a combination that enables applications from autoclave tooling to biocompatible medical devices.
The food-contact and biocompatibility approvals of the Stratasys ULTEM 1010 certified grade open doors to regulated industries where material safety is paramount. Combined with resistance to steam autoclaving, ULTEM 1010 serves applications from surgical instruments to food production, where it makes temperature-resistant dies, patterns and fixtures, high-temperature conveyor and packaging equipment parts and beverage-dispensing components.
From rapid prototyping to production runs, teams rely on ULTEM 1010 to maintain tight tolerances while reducing assembly complexity through consolidated part designs. Forge Labs' Fortus systems deliver consistent, repeatable mechanical properties, and a certificate of conformity traces every Stratasys ULTEM 1010 lot, giving aerospace, medical and food programs the documentation they ask for.
Flame retardant and electrically insulating, ULTEM 1010 also serves semiconductor manufacturing fixtures and hot-zone parts and insulating components in power and electrical equipment, and low-outgassing Stratasys ULTEM 1010 serves vacuum and space hardware.

- ULTEM 1010 has the highest heat resistance of any FDM thermoplastic and resists a wide range of fuels and industrial chemicals, making it suitable for aerospace and medical device applications. Stratasys ULTEM 1010 has a glass transition temperature of 209 °C and heat deflection of about 217 °C at 0.45 MPa and 215 °C at 1.82 MPa, reaches 79.2 MPa tensile strength along the layers and is rated UL 94 V-0.
- ULTEM 1010 is printed by FDM on Stratasys Fortus systems with heated build chambers, in 0.254 to 0.330 mm layers and parts up to 914 × 610 × 914 mm, with breakaway support. It is used for high-performance prototypes, composite and manufacturing tooling, and production parts exposed to high temperatures.
- ULTEM 1010 is used for composite lay-up tools, caul plates, vacuum-bagging mandrels, bonding jigs and trim and drill fixtures, out-of-cabin aerospace parts and ducting, under-hood automotive housings, ducts and heat shields, surgical guides and sterilizable instrument trays, and temperature-resistant dies, patterns, fixtures, conveyor and packaging equipment parts for food production. It also makes high-temperature manufacturing fixtures, environmental-chamber test fixtures, semiconductor fixtures and electrical insulation components.
- ULTEM 1010 keeps its shape under load above 200 °C, withstands composite cure cycles up to 177 °C, insulates electrically, and Stratasys rates it excellent against fuels and engine coolant. Stratasys ULTEM 1010 withstands steam autoclaving, is available in a certified grade with NSF 51 food-contact approval and ISO 10993 and USP Class VI biocompatibility, is rated UL 94 V-0 and shows low outgassing in ASTM E595 testing.
- Both are ULTEM 1010 PEI filaments for Stratasys Fortus systems, for high-heat tooling and parts. Stratasys ULTEM 1010 is tested on edge and upright to ASTM standards, is UL 94 V-0 on its UL Blue Card and shows low outgassing in ASTM E595 testing, and its certified grade is approved for food contact under NSF 51 and meets ISO 10993 and USP Class VI. Triton PEI 1010 is made from ULTEM 1010 resin, with a glass transition temperature of 217 °C by DSC; its values come from flat (XY) samples tested to ISO standards, so they are not directly comparable with the Stratasys ASTM values. The UL 94 listing, outgassing results and food-contact and biocompatibility approvals belong to Stratasys ULTEM 1010; Triton PEI 1010 has no published flammability, food-contact or biocompatibility rating. Each grade's datasheet lists its full test data.
- ULTEM 1010 costs more than standard FDM thermoplastics such as ABS, ASA and polycarbonate, and prints only in natural amber. Stratasys ULTEM 1010 is much weaker across the layers, at 28.2 MPa upright against 79.2 MPa on edge, so parts need careful orientation. Ketones, strong acids, halogenated hydrocarbons and phenols attack it, support is breakaway only, and the filament is moisture sensitive and must be dried and stored properly.
- Yes. ULTEM 1010 withstands steam autoclaving, and Stratasys lists surgical guides and instrument sterilization trays among its uses. The Stratasys ULTEM 1010 certified grade meets ISO 10993 and USP Class VI; Triton PEI 1010 has no published biocompatibility data. Stratasys's data sheet gives no ethylene oxide or gamma data and no cycle count, so the device maker validates the sterilization method for each part.
- ULTEM 1010 is used for out-of-cabin and high-heat aerospace parts and tooling. Stratasys ULTEM 1010 is rated UL 94 V-0, but current Stratasys data carries no FAR 25.853 flame, smoke and toxicity results, and Triton PEI 1010 has no published UL 94 or FAR 25.853 results, so cabin interior parts are printed in ULTEM 9085 or Antero 800NA.
