What it is
High-temperature 3D printing builds parts from the top tier of engineering plastics: PEEK, PEKK, PEI (sold as ULTEM), PPSU and PPS. These polymers keep their strength at temperatures that soften ordinary plastics, shrug off fuels, oils, solvents and steam, and weigh about half as much as aluminum. Pluribus Manufacturing prints them to order from your file, one part or a production run, with no mold and no block of expensive bar stock to machine away.
They are the materials engineers reach for when a part runs hot, sits in chemicals, slides against metal, must not burn, or has to come out of an autoclave unchanged. If your drawing says PEEK, ULTEM 9085, ULTEM 1010, PEKK, PPSU or PPS, this is the service for it. If it only says "must survive 180 °C" or "must resist brake fluid", tell us the conditions and we will recommend the lowest-cost polymer that does the job.
Why it takes a special machine
PEEK melts at 343 °C and wants to warp, crack and stay weak unless it is kept hot the whole way through the print. Each of these does a specific job, and each one shows up in the finished part.
01
PEEK, PEKK and ULTEM print at 370 to 450 °C. A nozzle rated to 480 °C melts them completely, so layers fuse into one solid part instead of sitting on top of each other.
02
The whole part stays hot while it is built. Heat leaves slowly and evenly, which is what stops tall or large parts from warping off the bed and cracking between layers.
03
The first layers stay bonded to the plate for the full print. Flat faces stay flat, and long parts keep their corners down.
04
Hot air treats each layer as it is laid down, so PEEK crystallizes during the print. Crystalline PEEK is the strong, heat-proof, chemical-resistant form. Parts come off ready, with no separate oven cycle to distort them.
05
A second nozzle prints a separate break-away support material, so internal channels, undercuts and overhangs are possible. It can also combine two materials in one part.
06
The print head is liquid cooled so it holds a steady temperature through prints that run for days inside a hot chamber. Steady temperature means the last layer is as sound as the first.
Materials
Start from what the part has to survive. Every material here is chosen for a different mix of heat, chemicals, toughness and cost.
| Material | Works up to about | What sets it apart | Typical parts |
|---|---|---|---|
| PEEK | 250 °C | The benchmark. Strength near 100 MPa, outstanding chemical and wear resistance, stands up to steam and hot water, self-extinguishing, very low moisture uptake. | Pump and valve parts, bushings, seals, insulators, metal-replacement brackets |
| Carbon-fiber PEEK | 250 °C+ | PEEK with chopped carbon fiber: far stiffer and more stable under load and heat, with low thermal expansion. The closest a printed plastic comes to aluminum. | Structural brackets, housings, tooling, motorsport and aerospace hardware |
| Glass-fiber PEEK | 250 °C+ | Stiffer and more dimensionally stable than plain PEEK while staying an electrical insulator. | Electrical housings, insulating structural parts, fixtures |
| PEKK | 250 °C | PEEK's close relative. Bonds better between layers and shrinks less, so large and thick parts hold shape. Excellent flame, smoke and chemical performance. | Larger structural parts, ducting, brackets, enclosures |
| ULTEM 9085 (PEI) | 150 °C | High strength for its weight and inherently flame retardant with low smoke. The grade aircraft-interior and rail engineers specify by name. | Ducts, clips, covers, cable guides, panels, tooling |
| ULTEM 1010 (PEI) | 200 °C | The most heat-resistant PEI, stiff and strong, and stands up to steam autoclaving. | Composite lay-up tools, hot fixtures, sterilizable trays and handles |
| PPSU | 180 °C | Very tough and impact resistant. Handles repeated steam sterilization and hot water without going brittle. | Sterilizable housings and trays, hot-water fittings, lab equipment |
| PSU | 150 °C | Rigid, clear amber, stable in hot water and steam at a lower cost than PPSU. | Fluid manifolds, sight parts, hot-water components |
| PPS and PPS-CF | 200 °C | Chemical resistance close to PEEK at a lower price, with very low moisture uptake and inherent flame resistance. Carbon fiber adds stiffness. | Chemical pump parts, under-hood parts, electrical components |
| PVDF | 150 °C | Stands up to strong acids, chlorine and sunlight. | Chemical-process fittings, tank and pipe parts, outdoor chemical service |
| High-temperature nylon (carbon fiber) | 150 °C | Stiff, strong and economical. Often all the heat resistance a part really needs. | Under-hood brackets, jigs, fixtures, end-use machine parts |
| Polycarbonate | 115 °C | Tough and impact resistant at a modest price. | Guards, housings, covers, fixtures |
Temperatures are approximate continuous-service figures from published data for each polymer. How a printed part behaves depends on its shape, print direction, load and environment, so send us your operating conditions with the drawing and we will recommend the material and print direction.
Lighter than metal
A PEEK part weighs about half as much as the same part in aluminum and about one sixth as much as steel. It does not rust, needs no coating, insulates electrically and runs against metal without galling.
By the numbers
Printed vs machined
PEEK is usually bought as rod or plate and milled down to the part. Printing changes the cost and the calendar.
01
PEEK stock is one of the most expensive plastics sold. Machining can turn most of a billet into chips. Printing puts material only where the part is.
02
Large PEEK rod and plate are often special order. A printed part starts from filament and your file.
03
Internal passages, curved channels, lattices and deep pockets print as easily as a plain block. Several machined pieces can become one part.
04
No fixtures, no programming and no setup charge spread over the batch. One prototype and fifty production parts are set up the same way.
05
A revised file is simply the next print. Test a design in the real material before committing to a machined or molded version.
06
Solid where the load is, lighter inside where it is not. The inside of the part is something you can specify.

Design guide
Send what you have. These are the points we will check with you before quoting.
01
Temperature, how long at that temperature, the chemicals, the load and where it is applied. The material choice and print direction come from these.
02
Printed parts are strongest along the layers. Mark the main load direction on the drawing and we orient the part to suit.
03
Keep walls even and avoid sudden jumps from thin to thick. Generous corner radii spread stress and print cleaner.
04
Flag bores, press fits and sealing faces. Tight fits can be left with stock and finished by reaming or machining after printing.
05
Large threads print. For small or heavily loaded threads, design for a tapped hole or a threaded metal insert.
06
One piece up to 300 × 300 × 400 mm, or 240 × 300 × 400 mm when a second material is used for support. Larger assemblies are designed in sections.

Yes. PEEK prints by FFF/FDM when the machine is built for it: a nozzle above 400 °C, a heated chamber and a hot build plate. Pluribus Manufacturing prints PEEK at up to 480 °C inside a 120 °C chamber and anneals it during the print, so the part crystallizes properly and comes off the machine strong and stable.
PEEK is one of the strongest unfilled plastics, with a published tensile strength near 100 MPa, and carbon-fiber PEEK is far stiffer. A printed part is strongest along its layers, so we orient the part to put your main load in that direction. Send the load and where it is applied with your quote request.
PEEK has a continuous service temperature of about 250 °C and melts at 343 °C. For comparison, ULTEM 1010 works to about 200 °C, PPS to about 200 °C, PPSU to about 180 °C and ULTEM 9085 to about 150 °C. Tell us the temperature and how long the part sees it, and we will recommend the material.
They are close relatives with similar heat and chemical resistance. PEKK bonds better between layers and shrinks less as it cools, so it is often the better choice for large or thick parts. PEEK is the long-established standard with the widest specification history. We quote either.
Both are PEI. ULTEM 9085 is tougher, lighter for its strength and known for flame retardance with low smoke, which is why it is specified for interior parts in aircraft and rail. ULTEM 1010 is stiffer, handles more heat (about 200 °C) and stands up to steam autoclaving, which suits tooling and sterilizable parts.
For many parts, yes. PEEK weighs about half as much, does not corrode, insulates electrically, resists most chemicals and runs against metal without galling. Aluminum is stiffer and conducts heat. Carbon-fiber PEEK closes much of the stiffness gap. If you tell us what the aluminum part does, we will tell you whether PEEK is a good swap.
Often, especially for one-off and low-quantity parts and for shapes with a lot of material removed. Machining starts from expensive rod or plate and cuts much of it away, plus programming and setup. Printing uses only the material in the part and needs no fixtures. Send the drawing and we will quote it.
PEEK is priced per part on a custom quote, because PEEK filament costs many times more than everyday plastics and prints run long and hot. The quote arrives within one business day. If PPS, PPSU, ULTEM or high-temperature nylon will do the same job for less, we will show you that option as well.
One piece up to 300 × 300 × 400 mm, or 240 × 300 × 400 mm when a second material is used for support. For bigger parts in engineering plastics and composites, see our large-format service, which prints up to about one meter in each direction.
Annealing is heat treatment that lets PEEK form its crystalline structure. Crystalline PEEK is the form with full strength, heat resistance and chemical resistance. Our process anneals each layer during the print, so parts do not need a separate oven cycle afterward that could warp them.
Both resist fuels, oils, hydraulic fluid, coolant, most solvents, many acids and bases, steam and hot water. PVDF is the choice for strong acids and chlorine. Tell us the exact chemical, concentration and temperature and we will match the material to it.
Yes. There is no minimum order. One prototype and a production run are set up the same way.
In the USA. We print in San Diego, California, and due to demand we have started setting up a new 5,000 sq ft facility in Yuma, Arizona, where lower energy costs let us offer lower prices on long, high-temperature prints. We are quoting PEEK, PEKK, ULTEM and PPSU projects now.
Yes. We sign and return an NDA within one business day, before you send files. Printers run on a segmented network under our own internal control and storage systems, not a cloud printing service.
