What post-processing is typically required for SLA prints?

Stereolithography (SLA) printing is a type of additive manufacturing that uses ultraviolet light to cure liquid resin into solid parts layer by layer. After the printing process, parts often require specific post-processing steps to achieve optimal results. The use of isopropyl alcohol (IPA) for rinsing the prints is critical because it removes uncured resin from the surface, ensuring a clean finish and preventing any potential curing issues.

Following the rinsing, post-curing under UV light is essential as it further solidifies and strengthens the printed parts. This step enhances the mechanical properties of the print, making it more durable and enhancing its overall performance. The combination of rinsing and UV curing is a standard practice for SLA prints to achieve the desired quality and functionality.

In contrast, other options involve techniques that may be relevant to different print technologies but are not typical for SLA prints. For instance, high-temperature ovens are generally not used for SLA, while spray coatings and manual sanding may apply to finishing techniques but don't address the fundamental need for post-curing and cleaning specific to resin-printed parts.
