High-Temperature 3D Printing: PEEK Material
What is High-Temperature 3D Printing: PEEK Material?
High-temperature 3D printing using materials such as Polyether Ether Ketone (PEEK) represents a cutting-edge segment in additive manufacturing, designed to meet the demands of high-performance applications. Known for its exceptional thermal stability, mechanical properties, and chemical resistance, PEEK is often the material of choice in industries like aerospace, automotive, and medical.
Layer Resolution
High-temperature printers that process PEEK typically offer layer resolutions ranging from 0.1mm to 0.3mm. Some advanced machines may achieve finer resolutions for intricate detail and smoother surfaces.
Material Compatibility
PEEK, PEI (ULTEM), and other engineering-grade thermoplastics that can withstand extreme conditions.
Build Volume
While varying greatly with the machine, high-temperature printers are often built for industrial purposes and therefore may offer substantial build volumes.
Support Structures
Support structures can be made from the same or similar high-temperature materials, ensuring stability during printing and ease of removal post-processing.
Support Structures
High-temperature 3D printing caters to sectors that demand parts capable of enduring harsh environments, such as heat-resistant components in aerospace and automotive industries, surgical and dental instruments in the medical field, and prototypes for new designs requiring rigorous testing.
CAPABILITIES
Temperature Resistance: PEEK parts can withstand temperatures up to 250°C and sometimes higher, making them ideal for applications that experience extreme heat.
Mechanical Strength: High-temperature 3D printed parts exhibit excellent strength-to-weight ratios, rivaling metals in some applications.
Chemical Resistance: PEEK is resistant to a wide range of chemicals, making it suitable for exposure to aggressive environments.
Biocompatibility: Certain grades of PEEK are biocompatible, which is crucial for medical implants and devices.
TECHNICAL SPECIFICATIONS
Print Speed: Varies based on the printer and complexity of the part but generally lower than traditional FDM due to the high-temperature requirements.
Print Temperature: PEEK typically requires an extrusion temperature between 360°C to 450°C.
Heated Bed: A heated print bed is essential, often operating at temperatures of 120°C or higher to ensure proper bed adhesion and to minimize warping.
Enclosed Chamber: A stable print environment with an enclosed chamber is necessary to maintain consistent high temperatures throughout the print process.
Why Choose High-Temperature Printing with PEEK?
Choosing high-temperature printing with PEEK is a decision driven by the need for components that offer superior thermal properties, durability, and longevity under stress. The investment in this technology is justified by the significant savings in weight, time, and cost over traditional manufacturing methods for high-performance parts.
