3D Printing Materials

Formula L1

Material Overview

Formula L1 is an excellent substitute for 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.



Highly accurate
Good resistance to humidity
Highly durable
Good resistance to yellowing
Suitable for a very wide range of applications


Functional prototypes
Concept models
Low-volume production parts
