Yes, absolutely...
The printing process does not fully cure the resin, additional exposure to UV after after printing is essential. I made a curing chamber from an old 0.7 ft³ microwave oven--I took out the magnetron, transformer, capacitor, etc. and installed a 30W 405 nm LED in its place. 40 minutes in this chamber will fully cure any print.
I have found that the less expensive, and water-washable resins are most susceptible to extended exposure to sunlight (the WW resin also deteriorated significantly in strength) even after my post-printing curing. 2-3 hours iin direct sunlight s all you need. For anything (printed with any resin) to be placed in service with continuous daylight exposure I use a UV blocking aerosol primer as used for stabilizing printed documents.
