PEEK and Ultem 3D printing is set for huge growth in the coming years, predicted to become a $1.1 billion industry by 2026, accounting for 19% of polymer 3D print material revenues. Both PEEK and Ultem offer fantastic heat, impact and chemical resistance, and both offer strength-to-weight ratios that surpass most metals — often replacing metal parts in the aerospace industry.
As a result, companies are turning to PEEK 3D printers to save weight, improve strength, and create the next generation of high performance prototypes.
- This article focuses on the best PEEK 3D printers. We also have an article on PEEK 3D printing.
The differences between PEEK, Ultem, PEI, PAEK, and PPSU
First invented in the early 1980s, PAEK refers to all the materials within the Poly Ether Ketones family — and includes PEEK, PEKK, and many others like PEK, PEEKK, and PEKEKK. Of these, PEEK is the only one to see wide use.
Ultem is the brand name for PEI products used by manufacturer SABIC, so if you see PEI 3D printers mentioned anywhere, it means Ultem. PEI is commonly used as a 3D printer heated bed material, but also has uses as a high performance polymer.
Ultem is similar to PEEK, just PEEK is semi-crystalline while Ultem is amorphous, which affects their heat resistances and glass transition temperatures. PEEK’s 143°C glass transition temperature is considered higher than Ultem, and it has slightly better tensile strength, but is also more expensive than Ultem. PEEK generally costs around $500 per kilo, whereas Ultem costs around $250 — though this can vary.
PPSU is similar to PEI in that it is a similar material that is also amorphous, but offers better impact and chemical resistance than Ultem.
All PEEK filaments will deteriorate if left in the open air, and it is integral to keep them away from open air and light when not printing.

What to look for in a PEEK 3D printer or Ultem 3D printer?
Peek and Ultem are far more difficult to 3D print than standard filaments like PLA or ABS. They are fantastically strong, and as a result need far higher extruder, heated bed and heated chamber temperatures to print effectively. As a result, you’ll need a high temperature 3D printer.
Extruder temperatures of 400°C are expected for a PEEK 3D printer, as well as a heated chamber of above 100°C, and a heated plate of easily 150°C. Since most professional 3D printers can’t handle these temperature levels, companies have developed specialized high temp 3D printers for PEEK, Ultem and Carbon fiber PEEK 3D printing.
Both PEEK and PEI / Ultem do not react well to undulating temperatures — a heated chamber that can keep temperatures very stable is crucial for high quality PEEK parts. Therefore, the PEEK printers we list all have high quality heated chambers and heat maintaining systems to prevent ruined PEEK or Ultem parts.
PEEK powders are also available for SLS 3D printers, and sold by German manufacturer EOS as their PEEK HP3 powder.

One of the smallest PEEK 3D printers on our list, the Apium P220 can 3D print PEEK, PEI and carbon fiber PEEK materials. You can even 3D print metal filled filaments like stainless steel, which can then be sintered.
Apium highlight how the P220 can 3D print PEEK in high crystallinity, creating fully crystallized parts using their specially-designed Adaptive Heating System. Carbon fiber PEEK filaments can be printed with up to 30% fibers.
Targeted towards the medical sector, the Apium P220 can 3D print medical implants and devices in its sterile and safe printing area using biocompatible PEEK material. It’s made from metals like titanium and steel within the build area, so any medical parts are safe to come into contact with them during the printing process.
Apium’s innovative Adaptive Heating System is their alternative to standard heated chambers. It involves the Ultem 3D printer’s nozzle moving with a heated surface, so as the Apium P220 prints, it also exerts heat on the uppermost layers. As Apium stress, the highest layers are the most important to heat at the time, and so the heated sits close on top of the part while the extruder prints, as their version of thermal post treatment.
Apium’s PEEK 3D printer features a camera system for easy monitoring of your part and the temperature for consistent temperatures. Some might expect less power as it’s a smaller 3D printer, but the extruder can reach temperatures of up to 540C, with up to 160°C on the print bed, and 180°C from adaptive heating. It’s also accurate, offering up to 0.05 mm layer thicknesses for precise and intricate PEEK part prototyping.

The printer also features dry air canisters for filaments using Essentium’s Filament Care System that retains your filament’s optimal properties, keeping them from the moisture in the air.
PEEK and Ultem 3D Printing Applications
Peek is used across the aerospace industry making parts that need to withstand powerful forces, as well as to make parts that come into contact with fuel, as its inflammability makes it an effective material for coming into contact with gas and oil. It’s used to replace the same metal parts when using PEEK saves weight — a huge money saver in aerospace.
In medical, PEEK and Ultem are used as they are sterilizable and biocompatible, making them ideal as 3D printable implants and for medical devices.
PEEK 3D printers are also used in education, such as in universities for research and development, and in the defense and architecture industries.
However, with PEEK being so expensive, it has not yet broken through into mainstream everyday use, and remains a niche high-performance material for industrial uses.
