Cleaning a Failed Print

Identifying a Failure

Before proceeding with the Failure Debris Cleaning method, we must first identify that there are failed models or cured pieces adhering the Resin Tank. Use the included rubber squeegee to safely check the inside of the Resin Tank after a print failure.

If there are only small pieces of cured material left behind that are not stuck to the Resin Tank, remove those pieces with a gloved hand, then survey the remaining resin for any remaining pieces, using the squeegee to gently mix resin and spot any floating remnants.

 

If there are no cured pieces remaining, AND no cured resin stuck to the Resin Tank, the following procedure is not necessary, and normal printing can proceed.

 

Example of models that failed to adhere to the platform and stuck to the Resin Tank:

This type of failure is not easily removed from the Resin Tank without the potential to leave behind pieces that could damage the Resin Tank during the next print job

If there are any floating pieces in addition to the cured pieces stuck to the tank,  remove them and dispose of properly before proceeding

 

Remove the Build Platform

Remove the Build Platform from the printer to prevent damage during the next step:

This step is CRITICAL! Failure to remove the build platform before performing this procedure will damage the Resin Tank and potentially cause other major issues

 

Print a Gap Test via RayWare

Open the RayWare software, connect to the printer, then go to

 

Print > Fine Tuning > Z-Axis Fine Tuning:

Then press the Print Gap Test button in the lower left hand corner:

The print arm will lower, and the Gap Test will begin:

Once complete, proceed to the next step

 

 

Gently Remove Cured Sheet

Using a gloved hand, gently feel inside the Resin Tank for the corner or edge of the cured Gap Test. Then, using a fingernail, very gently peel up the corner of the sheet away from the bottom of the tank. If the corner is too difficult to peel up with the fingernail, use a business card, playing card, or another soft tool (preferably paper or cardstock) to catch the edge of the sheet to easily peel.

DO NOT use a hard plastic or the included Platform Scraper, as this can damage the Resin Tank or Drum:

Here you can see the failed portions from the previous print job have stuck to the cured Gap Test, and are no longer adhered to the inside film of the tank:

Final Inspection

Once the sheet has been removed and disposed of, check the inside of the resin tank with a gloved hand for any remaining pieces or cured particulates that may have been left behind. If any portions failed to adhere to the Gap Test during removal, perform the procedure one more time.

Once the Resin Tank is clean, proceed to the next step

 

Cleaning the Build Platform

Use the included Platform Scraper tool to remove any failed remnants left on the build platform.

Then, ensure the build platform is completely clean and free of any stuck on debris. Any pieces left on the build platform will damage the film in the Resin Tank, and can potentially cause a leak
