Georgia Tech startup DDM Systems announces availability of commercial LAMP systems

Georgia Tech startup DDM Systems, Inc. today announced the availability of its first line of LAMP commercial systems in Q2 2015. The system will feature a reconfigurable build volume allowing small-lot prototyping (10 inches x 10 inches x 12 inches) to production (24 inches x 24 inches x 24 inches). The system will include all material preparation, handling and post-processing sub-systems.  DDM will also supply its proprietary software suite for digital build data preparation and design rule verification. Systems will be supplied with an initial set of ceramic material formulations optimized for the production of high quality industrial parts.
For more information on the system, see DDM's video on LAMP here:
