Unlocking High-Performance 3D Printing with PEI (Polyetherimide) at SGD 3D

Polyetherimide (PEI), commonly known by its trade name ULTEM™, is a high-performance thermoplastic renowned for its exceptional mechanical strength, thermal stability, and chemical resistance. At SGD 3D, we specialize in delivering top-tier PEI 3D printing services, catering to industries that demand precision, durability, and reliability.

What is PEI?

PEI is an amorphous, amber-to-transparent thermoplastic that offers a unique combination of properties:

  • High Thermal Resistance: With a glass transition temperature around 217°C, PEI maintains structural integrity under high-temperature conditions. JuggerBot 3D
  • Mechanical Strength: It exhibits high tensile strength and rigidity, making it suitable for load-bearing applications.
  • Chemical Resistance: PEI resists a wide range of chemicals, including hydrocarbons, alcohols, and aqueous solutions.
  • Flame Retardancy: Inherent flame-retardant properties make it ideal for applications requiring compliance with fire safety standards.
  • Dimensional Stability: PEI maintains its shape and size over a wide temperature range, ensuring consistent performance.

SGD 3D's PEI 3D Printing Services

At SGD 3D, we utilize Fused Deposition Modeling (FDM) technology to produce high-quality PEI parts. Our services include:

  • Rapid Turnaround: Lead times as short as 1 to 3 working days, depending on project complexity.
  • Precision Printing: Layer heights between 100 – 200 microns, with tolerances of ±0.60 mm below 100 mm and ±0.75% above 100 mm.
  • Versatile Part Sizes: We can produce parts up to 260 x 260 x 260 mm, accommodating a wide range of project requirements.

Applications of PEI 3D Printing

PEI's properties make it suitable for various industries and applications:

  • Aerospace: Ideal for out-of-cabin components, ducting, and semi-structural parts requiring high strength-to-weight ratios.
  • Automotive: Used for under-the-hood components, housings, and ducts that must withstand high temperatures and chemical exposure.
  • Medical Devices: Suitable for surgical guides and medical tools that require sterilization and biocompatibility.
  • Food Processing: Applicable in creating temperature-resistant dies, patterns, and fixtures for food production.
  • Electronics: Employed in producing enclosures and housings that require electrical insulation and thermal stability.
