What is LAMP?

Georgia Tech spinoff DDM Systems introduced a technology for production of large size ceramic foundry cores. Its Large Area Maskless Photopolymerization — or LAMP for short — process is actually a type of stereolithography (more similar to Prodway’s MOVINGLight technology) which is used primarily for the production of ceramic cores and integral cored shell molds for precision investment castings, as well as intricate engineered ceramic components without hard tooling. As well as their additive manufacturing solutions, DDM Systems also provides targeted testing, prototyping, and process optimization services for a select number of clients.

  • Large part size capabilities
  • Ongoing development
  • High speed
  • Limited commercial availlability
  • Low resolution

How does LAMP work?

LAMP technology platform effectively integrates maskless optical imaging to ensure higher throughput with UV light photopolymerization of slurry ceramic resins to additively produce cores and integral-cored shell molds directly from CAD. Green parts need to be post-processed through binder burnout and high-temperature firing to produce dense ceramic parts suitable for investment casting.

The platforms thus efficiently replace costly multi-step and low-yield lost wax investment casting processes, eliminating the need for core tooling design, core tooling manufacture, and ceramic injection. Through direct digital manufacturing of integral-cored molds, the LAMP platform also eliminates 7 out of 12 major process steps in state-of-the art investment casting (core and wax tooling design, core and wax tooling manufacture, ceramic injection, wax injection, wax melt out, slurry coating, and stucco coating, thereby eliminating even more of the associated costs, lead time, rework and scrap.
