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
Level
Process
Description
1
Supports removed and support surfaces lightly sanded
Standard finish, supported surfaces appearing dull. Parts will have visible lines.
2*
Supports removed, support surfaces lightly sanded, and entire part bead blasted
Even surface finish, more consistent matte finish. Parts will have visible layer lines.
2 +*
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.
3*
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.
4*
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.
