Physical Steps to Change Print Material

The NextDent 5100 can print with many different NextDent resins. Please see the section Print Material Bottles for a full list of supported resins. This section describes the steps that are necessary to cease using one resin type in the printer, and to begin using another resin type. You should have already scanned the new resin into the printer's memory in the previous section.

Resins can leave residual material in the resin tray, even when cleaned well. For this reason, some resins cannot be used in the same tray that held another resin type. The section Resin Tray Material Cross-Usage details which resins are compatible with each other and can be used in the same tray. If the resin you are switching to is not compatible with your original resin, you must use a new resin tray for the new resin. The following procedure will walk you through switching resins in both scenarios.

  1. Remove the print platform and resin tray, cleaning them both, as per the sections Clean Print Platform and Clean Resin Tray.


  1. After removing the resin tray, label it on the outside with an identifying number, letter, or word(s) to let you know which resin was in it before. For the sake of this example, we are using the Resin Tray Material Cross-Usage chart as a guide.
  1. If the catch-tray glass has a large amount of spilled resin on it, you must dispose of it according to all government regulations and replace it with a new catch tray. If it has no resin, or just a few resin spots on it, clean the glass with >90% alcohol solvent on a nonabrasive cloth, according to the section Clean/Replace the Catch Tray.
  1. Reinstall the print platform.
  1. As discussed in the introduction to this section, you will now either install a new resin tray or reinstall the cleaned old one, as per the section Install Resin Tray.
  2. If this is a new resin tray, label this tray with the same naming convention used in Step 2.

You are now ready to perform the print process with a new resin.
