Pure BLK
Pure BLK is a special black light-curing molding resin for SLA. The samples printed with it are matte and pure black, with high color saturation and no need for spray painting. This greatly simplifies the post-processing process and is suitable for model printing that requires color in the electronics industry.

Painting
Finish options
Glossy and matte paint finishes available
Best for
Adding custom color and a protective paint layer to Pure BLK parts for appearance and display models.
Note
Validate paint adhesion, masking boundaries, and coating coverage on Pure BLK before production, especially around interfaces, edges, and fine details.
Silk Screening
Print method
Single- or multi-color graphics on flat or gently curved surfaces
Best for
Applying logos, labels, or functional graphics to flat areas of Pure BLK parts used for appearance and display models.
Note
Confirm printable area, ink adhesion, and graphic registration on Pure BLK before production.
Vacuum Plating
Finish options
Glossy and matte plated finishes available
Best for
Creating a reflective metallic finish on Pure BLK parts for appearance and display models and appearance-led builds.
Note
Confirm line-of-sight coverage, masking, and plating adhesion on Pure BLK before production.
Polishing
Surface result
Smoother, glossier visible surfaces where geometry allows
Best for
Improving smoothness and gloss on Pure BLK parts used for appearance and display models, where geometry permits.
Note
Confirm edge retention and dimensional impact on Pure BLK; fine features may soften during polishing.
