What is one advantage of using a heated bed in the printing process?

Using a heated bed during the printing process offers significant advantages, particularly in terms of warping, which is a common issue when printing with materials like ABS or PLA. A heated bed maintains a steady temperature that helps keep the lower layers of the print warm and adhered to the print surface throughout the printing process.

When the material cools too quickly, it can contract, leading to warping as the print pulls away from the build surface. A heated bed mitigates this risk by ensuring that the print retains a consistent temperature, which is crucial for successful adhesion and layer bonding. This temperature stability fosters a more uniform cooling process, ultimately leading to a better quality print with fewer defects.

While the other options may relate to certain aspects of 3D printing, they do not directly address the primary functionality and benefits of a heated bed like minimizing warping does.
