The photosensitive resins used in SLA are by far the most popular printing materials, offering sharp details, high surface quality, accuracy of up to 0.05mm or 0.4% (whichever is greater) and a wide range of affordable options. SLA photosensitive resins need to be cured by a chemical cross-linking reaction triggered by UV light, so the performance of the print material is largely determined by the chemical reaction itself, such as print speed and print shrinkage, and a good 3D print design needs to be able to take into account these systematic errors related to the nature of the material and process in advance, in order to optimise the execution of 3D printing.

 

Resin characteristics: good rigidity, excellent sharp corners, minimal shrinkage at the bottom, excellent surface detail, extremely textured white, fast print speed

 

Suitable industries and applications: industries with high detail requirements, ideal for the handboard industry, making car parts, toys, crafts, etc., suitable for mass production of consumer goods and electronic products
