Formula L1

 

ProtoFab Formula L1 Material Overview

Formula L1 is an excellent substitute for sla abs in 3D printing. Its opaque white color resembles ABS closely, and its physical attributes make it suitable for almost any application. Aside from being strong, it is also highly practical to work with as it only requires the very minimum of post-processing.
