What is a common challenge associated with using SLA printing?

One of the common challenges associated with SLA (Stereolithography) printing is the need for post-curing to achieve final properties. After the printing process, parts created through SLA are typically not fully cured and can be somewhat soft or fragile. To attain the desired mechanical properties and surface finish, these parts require additional exposure to UV light during a post-curing process. This step enhances their strength, durability, and stability, thus ensuring that the final product meets the necessary specifications.

While there are several other factors that might influence the choice of SLA printing—such as the material costs, printing speed, or environmental requirements—post-curing is a critical aspect that directly impacts the usability and integrity of the printed parts. Addressing this challenge is essential to achieving high-quality results in SLA applications.
