Resin is made up of several components including color pigments, which tend to settle at the bottom of the bottle.Therefore, before pouring resin into the resin vat, it is essential to shake the resin bottle thoroughly for 30 seconds to one minute.
As resin is shaken, the sediments will distribute evenly, meaning that you can create successful 3D prints more easily. If you don't shake resin before pouring it into the resin vat, it will cure unevenly, and your prints may fail.
Resin bubbles are considered as the main cause of holes on the top of prints. Another benefit of shaking resin prior to pouring it into that resin vat is that this can help to reduce resin bubbles. If you still notice some bubbles in the resin vat, just use a plastic scraper to mix the resin and get rid of the bubbles.
When pouring resin, make sure it does not exceed half the height of the resin vat. This prevents resin from overflowing during the printing process which could cause damage to the LCD screen.
