I ran some exposure tests last night. I placed a small amount of UV resin into a plastic sandwich bag and laid it flat on the Resin tray. I went to a middle layer slice of a model slice and I let the resin expose for approximately 30 seconds.

| Exposing the Resin to the projected image |
As you can see, the resin set into the slice of the projected image. Exposure time took longer than I thought it would, and the resultant piece was still very soft and rubbery. I think I'm using a non-optimal UV resin for this printer. (I bought a quart over 2 years ago from www.solarez.com that was meant for surfboards). I need to bite the bullet and invest in a small quantity of of resin that is specifically designed for 3d printing.
The resultant created object.
If anyone knows of a site where I can purchase a small (quart or liter size) amount of UV resin specifically designed for 3D printing, please let me know.
