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.
Advantages
Highly accurate
Good resistance to humidity
Highly durable
Good resistance to yellowing
Suitable for a very wide range of applications
Applications
Functional prototypes
Concept models
Low-volume production parts
