This source index links technical and program statements on Rapid Precision Castings to patents, government-supported project records, and peer-reviewed research. Project records document participants, objectives, budgets, schedules, and intended deliverables; they do not by themselves establish that every target was achieved.
LAMP™ ceramic 3D printing and investment casting
- U.S. Patent 9,403,322 — Systems and methods for fabricating three-dimensional objects. Patent record describing LAMP-related ceramic photopolymerization and investment-casting applications, including integrated casting features.
- America Makes / AFRL project 5554.004. Public project record naming DDM Systems, America Makes, NCDMM, the 76th CMXG at Tinker AFB and the Air Force Sustainment Center; it states the maturation and qualification objectives for LAMP-printed ceramic shells.
- America Makes / AFRL project 5577.005. Public project record for rapid investment casting with ceramic 3D-printed shell molds, including participants, funding, technical approach, deliverables and the target of documenting total processing time against a 10-day goal.
SLE™ additive manufacturing and repair
- U.S. Patent 9,522,426 — Systems and methods for additive manufacturing and repair of metal components. SLE patent family record covering epitaxial additive manufacturing and repair.
- U.S. Patent 10,639,721 — continuation in the SLE patent family. Additional claims and disclosures for additive manufacturing and repair of metal components.
- Basak and Das, Journal of Alloys and Compounds (2017). Peer-reviewed study of MAR-M247 deposited through SLE, reporting single-pass deposits exceeding 1.5 mm on like-chemistry substrates and characterizing microstructure.

- Basak and Das, Additive Manufacturing (2018). Peer-reviewed research on epitaxial deposition of René 142 on René N5 substrates using SLE.
- Feedback Control of Scanning Laser Epitaxy (2019). Technical paper describing thermographic feedback and process-control development for SLE.
Use and limitations
These sources support the specific technology, research, or program statements described above. Customer relationships, contract completion, production delivery, cost savings, lead times, and qualification status require separate claim-specific documentation. A proposal, project objective, or target is identified as such and should not be read as a completed result.
