PEEK 3D printer 2020: best 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.

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, etc.

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 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.

Alternatives for specific needs

Medical PEEK 3D printing

PEEK is a great material for medical applications (e.g. medical PEEK implants) since it is biocompatible.

The two main medical PEEK 3D printer brands are Apium and VeraShape.

Cost-effective PEEK printers

If you have a smaller budget but you’re willing to spend a lot of time on tweaking and adjusting, there are more affordable options out there from Chinese brands such as IEMAI, CreatBot, or INTAMSYS.

CreatBot, for example, has really been emerging this past year with a number of industrial-grade printer releases. They offer pretty good price-to-performance ratios and are available worldwide.

Affordable PEEK printer prices can start from around $6,000. They are able to print PEEK, but the resulting quality may not meet your standards, especially in terms of repeatability.

Don’t hesitate to reach out to us to get advice and quotes, and see if PEEK is really what you need for your project.

Custom PEEK 3D printers

Some brands like Tobeca, Qualup (SpiderBot), or Hyrel 3D aren’t widespread but offer interesting, tailored solutions for PEEK 3D printing.

Their custom PEI/PEEK 3D printers can be suitable for R&D applications or any case where specific sizes and components are needed.

Large, industrial PEEK 3D printing systems

Warping is often an issue when 3D printing large parts. Hence, 3D printing large parts with a thermoplastic as challenging as PEEK is double the risk.

Some manufacturers that are specialized in large scale 3D printers claim that they are also able to print PEEK (e.g. Stratasys, BigRep, CEAD, Cosine Additive, etc.).

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® 3D printing-compatible filament has received aerospace certifications.
  • 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.

Applications for PEEK and ULTEM 3D printing

PEEK and ULTEM® 3D printing is mostly useful for manufacturers requiring strong prototypes and/or end parts that can withstand extreme conditions, in a variety of industries.

Some manufacturers even present PEEK 3D printing as an alternative to 3D printing metal parts.

Aerospace, automotive and military

Being lightweight yet strong and resistant, PEEK and ULTEM® 3D printed end parts are increasingly popular in aerospace, automotive and military fields.

Oil and gas

Thanks to PEEK’s chemical resistance and impermeability, oil and gas manufacturers can use the material to 3D print air valves and other parts.

Medical implants

PEEK and PEI are biocompatible, and can therefore be used for implants or other medical use cases.


With PEEK’s electrical integrity it is possible to 3D print flexible circuit boards, as well as wire and cable insulation.

Cost of PEEK and ULTEM® (PEI) 3D printing

PEEK 3D printers and ULTEM® 3D printers price

Most PEEK-ready 3D printers are available at prices ranging from $20K to $100K, and can even go up to $250K. It might seem like a hefty price tag, but these professional additive manufacturing systems feature specific technology that is difficult to integrate into a machine.

However, some PEEK 3D printers under $10,000 do exist.

PEEK and ULTEM® filament price

PEEK filament price

Polyetheretherketone (PEEK) material is among the most expensive plastics on the market: its price can range from about $400 to $700 per kilo.

ULTEM® filament price

PEI, or ULTEM®, is a cheaper alternative to high-performance PEEK material. The cost per kilogram can vary between 150$ to around 280$.
