01
Legacy system sustainment
Reconstruct unavailable components and create controlled technical data for aging equipment and long-life platforms.
Federal + prime contractor support
Engineering support for the mission behind the machine.
MIDDLESYS helps government programs and defense-industry partners sustain legacy equipment, resolve mechanical challenges, and move technical work from physical artifact to production-ready definition.

Responsive technical capacity for high-consequence work.
MIDDLESYS is a small, minority-owned Detroit manufacturer and engineering company built for direct communication, controlled execution, and practical problem solving.
02
Mechanical engineering
Design, analysis, drafting, and production engineering support for mechanical systems, products, and components.
03
Additive manufacturing
Large-format SLA and FDM capacity for prototypes, tooling, fixtures, bridge production, and end-use polymer parts.
04
Production support
Technical data packages, first-article support, process improvement, and responsive sub-supplier engineering.
02 Sustainment advantage
When the drawing is missing, the equipment still has to operate.
Legacy parts are rarely just geometry. Their interfaces, loads, materials, wear patterns, and production constraints all matter. We combine physical inspection, 3D capture, parametric CAD reconstruction, and prototype validation to create a supportable replacement path.
- Obsolete and hard-to-source component recreation
- Digital model and drawing development
- Form, fit, and function validation
- Prototype, tooling, and low-volume production support
