What is bed weld used for in 3D printing?

Bed weld is a term commonly used in the context of 3D printing to refer to a material or treatment applied to the print bed that enhances the adhesion of the printed part during the printing process and facilitates easy removal after printing. This is crucial because effective material adhesion is necessary to prevent warping and to ensure that the print stays in place while layers are being built up.

When a print adheres well to the bed, it prevents issues such as shifting or curling, which can negatively impact the print quality. Once the print is complete, a good bed weld can help in providing a clean release, allowing the printed object to be removed easily without damaging either the model or the print bed surface.

This adhesive property is important, especially for various thermoplastic materials used in 3D printing, as they generally require specific conditions to stick firmly to the bed during printing and then be easily detached once printing is complete. The option that indicates its role in enhancing both adhesion during printing and ease of release after, embodies the true function of bed weld.
