Cure and Wash

Post-curing refers to the process of exposing a freshly 3D-printed item to additional light and heat treatment. This treatment enhances the polymerization process, ensuring that the resin or other material used in the printing fully cures, hardens, and attains its desired mechanical properties.

Resin 3D printers use UV light to build models layer by layer from a vat of photosensitive liquid. When the print is finished, you’re left with a soft model still coated with resin that needs to be cleaned and fully cured with additional UV light.

Post-curing is an essential step, especially when working with biocompatible materials, such as certain Dental Resins. This process is crucial to achieve the highest level of strength and durability in the final print.

Typically, the time required for resin prints to cure varies based on several aspects like the print’s dimensions, Resin type and curing machine light intensity. However, PioCreat’s advanced curing machine can efficiently solidify standard-sized dental resin models in just 1 to 5 minutes.

There are several reasons why UV resin can be tacky after curing. One possible cause is inadequate curing time. If the resin is not exposed to enough UV light or if the light source is not strong enough, the resin may not fully cure, resulting in a tacky surface. Another reason for stickiness is that the surface of the model is not clean.
