Digital Light Processing (DLP)
UV-sensitive liquid resins are cured by a digital light projector. After processing, the part is cleaned, supports removed and then UV and/or thermal treated when necessary. ***Also known as DLS, CLIP
Digital light processing is an ideal option for projects that require high detail and finish in a variety of production-grade materials. From flexible silicone to rigid high-temp cyanate ester DLP can make parts with different durometers and characteristics, . It’s great for small end-use parts, light metal part substitutions, functional, high-detail prototypes, jigs, and fixtures.

Digital Light Processesing Finishing Levels
Supports removed and support surfaces lightly sanded
Standard finish, supported surfaces appearing dull. Parts will have visible lines.
Supports removed, support surfaces lightly sanded, and entire part bead blasted
Even surface finish, more consistent matte finish. Parts will have visible layer lines.
Supports removed, support surfaces lightly sanded, and cosmetic surfaces sanded to 180 grit and bead blasted
Functional finish, removes some layer lines. Parts have a light texture from sanding.
Supports removed, support surfaces lightly sanded, and cosmetic surfaces sanded to 320 grit
Show quality finish, removes most visible lines. Parts are prime and paint ready.
Supports removed, support surfaces lightly sanded, and wet sanded to 600 grit
Recommended only for plating.
* Elastomeric materials can only be finished to Level 1. For a higher quality finish, these materials may be coated in soft touch.
