PEEK 3D printer 2021: high-temp 3D printers for PEEK and PEI (ULTEM)

PEEK and PEI thermoplastics are increasingly popular for use in demanding industries, but are hard to print, requiring extremely controlled, high-temperature environments. This guide includes our expert selection of the best PEEK 3D printer options available today as well as professional insight into this niche material.
We updated our main selection (+ Roboze and Stratasys) and runner-ups section, removing discontinued products and adding recently announced printers (+ Zortrax and WASP). Further information was added throughout the guide regarding crystallization, medical printing, and other minor details.

PEEK and ULTEM® (PEI): high-performance materials

PEEK and ULTEM® (PEI) are derived from PAEK (polyaryletherketone), a semicrystalline thermoplastic. These high-performance materials:

  • boast high mechanical strength,
  • are resistant to extreme temperatures and to most chemicals,
  • all while being lightweight.

To 3D print PEEK and ULTEM® filament, you need a high-temperature 3D printer with an enclosed, heated environment and a high-temperature extruder.

What are the best PEEK/PEI 3D printers?

Whereas the PEEK 3D printer market used to be a niche with very few players, today many manufacturers claim that their printers are suitable for PEEK and PEI 3D printing.

Boasting high-temperature extruders and heated chambers is often not enough, however. PEEK and PEI are tough thermoplastics to print, and many elements come into play in order for prints to be a success.

Our goal here is to select PEEK/PEI printers that stand out from the rest, and not only in terms of hardware. We’re also taking into account a range of factors such as manufacturer maturity, feedback from our network, availability, and distribution.

Of course, this doesn’t mean they’re the only ones out there, but in our eyes they are top-tier PEEK 3D printers. Promising emerging brands, cost-effective printers, and case-specific machines are mentioned in separate sections so as to provide a comprehensive overview nonetheless.

We work with a large number of distributors and brands worldwide– contact us for a personalized recommendation based on your project and location.

Key characteristics and properties of PEEK

Pros of PEEK filament

PEEK is dimensionally stable. It can tolerate significant changes in temperature, moisture, and other conditions.

  • Useful operating temperature of up to 250°C-260°C
  • Low flammability and low levels of toxic emissions during combustion
  • High mechanical strength (see Engineering.com’s article for more technical details)
  • Low moisture absorption; water and steam resistant
  • Chemical resistance (with exceptions)
  • Biocompatible
  • Lightweight

PEEK drawbacks

This material also has a few limits.

  • Complex to 3D print
  • PEEK prices are relatively high
  • Mostly only comes in shades of one, beige-like color
  • Low impact strength
  • Non-resistant to UV light

PEKK (Poly Ether Ketone Ketone): a good alternative to PEEK

PEKK and PEEK are both part of the same polymer family called PAEK (Poly Aryl Ether Ketone). They boast similar properties in terms of strength, chemical resistance, and more. However, PEKK can be easier to process in 3D printing.

It is possible for filament manufacturers to tweak its melting point, and therefore generally requires lower temperatures. PEKK can also have a slightly higher glass transition temperature (Tg) than PEEK.

Find out more about PEKK in this guest post: PEEK vs PEKK.

Requirements for 3D printing PEEK and PEI high-performance materials

High-temperature extruder

The melting point for PEEK materials is 343°C. This means that the extruder needs to be able to reach that temperature or higher.

The hotend extruder must also be all-metal and be resistant to abrasions.

Heated print bed

To print PAEK high-performance polymers, a heated bed is mandatory, and it must be able to reach temperatures of 120°C at the very least.

This ensures correct adhesion and overall 3D print quality.

Closed, heated chamber

PEEK is highly prone to shrinkage and warpage (sometimes called warping).

Ideally (and this is especially important for larger parts), the chamber temperature should be able to go up to or over 143°C, which is PEEK’s glass transition temperature (Tg).

It is extremely important to be in control of these temperatures and to keep them constant, as fluctuations can easily affect print quality. However, these aren’t the only conditions for printing high-quality PEEK parts; post-treatment also plays a major role.

In order for PEEK to crystallize as well as possible – and thus for the printed parts to be as strong and stable as possible – the material must be cooled gradually.

Unlike PLA parts, which can be removed from the tray almost as soon as they are printed, waiting several hours for the temperature of a PEEK or ULTEM part to drop to room temperature is necessary. This avoids disturbing the material’s crystallization process.

Some PEEK printers provide precise control over the chamber’s cooling rate.

PEEK and ULTEM® are quite similar, but have their differences:

  • Cost: ULTEM® is more cost-effective than PEEK.
  • Impact strength: PEI has lower impact strength than PEEK.
  • Tensile strength: PEEK has higher tensile strength than PEI.
  • Certifications: ULTEM® (especially the 9085 blend) has received numerous aerospace certifications and is easier to 3D print.
  • Temperature resistance: PEEK features higher temperature resistance than PEI.

Difference between PEI and ULTEM®

ULTEM® is actually a brand of PEI manufactured by SABIC, a company based in Saudi Arabia. Most 3D printer manufacturers and filament resellers use SABIC’s name, ULTEM®, as it is the only brand of PEI base material available on the market.

SABIC sells PEI (ULTEM®) in the form of resins or foam. Smaller resellers then transform it into granulates, filament, etc.
