Gap Test

If your prints are falling from your platform and/or peeling around the edges, your support technician may instruct you to run the Gap Test. 

What you'll need:

Paper towels, putty knife, calipers, gloves.


To begin, ensure that your printer's tank has resin to at least the minimum fill line.

Note: The gap test is traditionally performed with gray resin only. If you do not have access to SprintRay Gray resin, contact your support tech.

Open RayWare and drag the Gap Test .SSJ file into the software. Press 'Print SSJ'. 


The print arm will now lower into the resin, and your printer will cure a single 100-micron layer. This process should only take a few minutes. Once the build platform has returned to its full height, the test is complete.

Note: Because only a single layer has been printed, it can appear as though nothing has printed at first glance. 


Remove the build platform.


Once some of the excess, uncured resin has dripped from the platform, it should look like this:


Note the thin rectangle. Using a paper towel, wipe off the build platform to whisk away excess resin.



Gently use your putty knife to peel the single layer of cured resin from your build platform. 

Note: Because it's extremely thin, the gap test rectangle is prone to breakage. If it cracks, don't panic. Move to a different part of the rectangle and begin peeling again. 



Use your calipers to measure the thickness of each corner of the gap test rectangle. Write down the exact thickness.
