If you are new to the amazing world of physical printing, you may want to learn how to clean a glass bed on a 3D printer. Some of the best printers, after all, are 3D printers, and these models can include glass beds where 3D models are made. So why keep your glass bed clean, and what are some tips for performing this task for the best 3D printers and their glass beds? Keep reading to find out.


  • A printer’s bed is where the 3D model sits as it is being built via the extrusion nozzles.
  • The bed is typically a glass surface, and these print surfaces become littered with debris and glue stick residue after just a couple of prints.
  • Clean this item by removing the bed from the printer and scrubbing on some glass cleaner with a microfiber cloth.

Why Clean a Printer Glass Bed?

The printer bed is where the 3D models rest when being built, so you are going to want to learn how to clean a 3D printer bed. Not all of these beds are made from glass, but many are, leading consumers to research how to clean the glue off of a 3D printer bed. Simply put, a debris-laden bed will lead to many issues, from sticky objects to lengthier print jobs.

Insider Tip

You should make a habit out of cleaning your plate or bed after every print job.

3D printers are serious investments, so protect that investment by keeping all of the components clean and properly maintained.

Tips to Clean a 3D Printer Glass Bed

Each printer is unique, and the same is true of each glass bed, though they are all made of glass. In other words, there may not be a universal cleaning process that handles every printer on the market, but you can apply what you know about glass cleaning here.

Remove the Glass Plate

First of all, you want to really get in there to clean every nook and cranny, as glass beds come into contact with various adhesive and filament materials. Luckily, the vast majority of these glass beds are easily removed. Consult the instructions for an exact removal process, but it should be a simple plug-and-play affair, or in this case, an unplug-and-clean affair. Once the plate is removed, the cleaning process will be simplified.

STAT: 3D prints can fail for a variety of reasons, and one of the most common is a part detaching from the print bed mid-print. As such, ensuring proper bed adhesion is crucial for successful printing. (source)

Use Standard Glass Cleaner

You should be able to use an average glass cleaning solution to clean the glass plate once it is removed from the enclosure. Spray it down and then wipe it down with a microfiber cloth.
