Tooling-free investment casting gives aerospace sustainment teams another sourcing path when legacy suppliers or wax-pattern tooling are unavailable
ATLANTA, GA, UNITED STATES, September 4, 2026 /EINPresswire.com/ — DDM Systems | Rapid Precision Castings is urging aerospace OEMs, MROs, defense initiatives, and fleet-support entities to assess at-risk cast components well before exhausted stock, missing tooling, or a lost supplier turns a controllable supply challenge into a grounded-aircraft crisis.
This advice comes after two major aerospace-engine sustainment announcements.
Safran posted a 27.9% increase in civil-engine spare-parts revenue (USD) for the first half of 2026. The firm attributed much of that growth to the CFM56’s favorable workscope mix and comparison baseline. Expanding LEAP shop visits performed by third-party MROs along with broader workscope also played a role.
Separately, RTX disclosed that Pratt & Whitney was awarded a nearly $1.3 billion undefinitized Indefinite Delivery, Indefinite Quantity contract for fiscal-year 2026 F135 initial spare parts, deployable spare packages, depot lay-ins, and related support equipment.
DDM Systems is not involved in these announcements. They are referenced as industry context showing the ongoing importance of spare-part availability in both civil and military aviation.
Legacy casting risk often surfaces well before the part becomes urgently needed
Aerospace sustainment teams may face sourcing difficulties when:
• Original wax-pattern tooling has been lost, damaged, or decommissioned
• The original casting supplier has ceased operations or no longer supports the component
• Required volumes are too low to justify recreating traditional hard tooling
• Existing tooling introduces excessive cost or delays
• Controlled CAD, drawings, or process records are incomplete
• A replacement source must go through inspection, qualification, or approval
DDM Systems examines whether suitable parts can be produced using LAMP™, its patented ceramic additive-manufacturing process. LAMP™ creates ready-to-pour investment-casting molds with integrated cores directly from controlled digital geometry, eliminating the wax-pattern tooling stage.
For projects that need cast metal parts rather than only ceramic molds, DDM’s DirectPour™ workflow coordinates the path from customer CAD and alloy specifications through casting, inspection, and finished-part delivery.
“The best time to evaluate a legacy casting is before the last serviceable part is installed,” said Dr. Suman Das, Founder and CEO of DDM Systems. “If the original tooling or supplier is no longer available, directly printed ceramic molds may remove a major sourcing obstacle. The technical definition, alloy, inspection plan, traceability requirements and approval path still need to be addressed, but the program does not necessarily need to recreate the entire conventional tooling process.”
Technical readiness determines the available recovery path
An initial legacy-part review considers:
• Part number, nomenclature, and controlling revision
• Released CAD files and engineering drawings
• Alloy, heat-treatment, and casting specifications
• Required quantities and delivery schedule
• Critical dimensions and acceptance criteria
• Nondestructive examination and material-certification requirements
• Existing inventory, tooling, and supplier status
• Design-authority and source-approval responsibilities
Based on those inputs, DDM Systems can assess the need for a directly printed LAMP™ ceramic mold, a DirectPour™ finished-casting scope, or additional technical-data development before casting feasibility is determined.
Direct ceramic-mold printing changes how the mold is made. It does not approve a component for installation, establish missing design requirements, or replace applicable engineering and airworthiness controls. Design authority, source approval, first-article inspection, material qualification, traceability, and release-to-service obligations remain with the responsible organizations.
Submit an at-risk casting before it becomes an AOG requirement
Aerospace OEMs, Tier suppliers, MROs, government program offices, and fleet-support organizations can submit a single component or a group of at-risk part numbers for review.
