PEI or Glass: Which 3D Print Surface is Best?

Printing 3d

In the world of 3D printing, the choice of print bed surface is crucial to the success of your projects. Two of the most popular options are PEI (Polyetherimide) and Glass. But which of the two materials is best for your 3D printing needs?

In this article, we will explore the advantages and disadvantages of both to help you make an informed choice.

Benefits of the PEI:

  • Optimal Adhesion: PEI is known for its excellent adhesion when heated, meaning your models will stay put while printing.
  • Easy to Remove: Once cooled, PEI easily releases the printed model, reducing the risk of damaging both the print and the plate surface.
  • Durability: PEI is durable and can be used repeatedly without the need for frequent replacement.

Advantages of Glass:

  • Smooth Finish: A glass surface leaves a smooth, glossy finish on the bottom of your models, which is often desirable for professional-looking pieces.
  • Heat Resistance: Glass, especially borosilicate glass, is very heat resistant, making it ideal for materials that require high printing temperatures.
  • Easy Cleaning: The glass can be easily cleaned with alcohol or water, keeping the surface ready for your next print.

Final Considerations

The choice between PEI and glass largely depends on the type of material you are printing and your personal preferences. If you’re looking for a surface that offers easy pattern removal and minimal maintenance, PEI may be the right choice for you. On the other hand, if you prefer a smooth surface finish and greater heat resistance, glass may be better suited.

In conclusion, both PEI and glass have their strengths and may be the best choice depending on the circumstances. Carefully evaluate your needs and printing material specifications to make the best decision for your 3D printing lab.
