Additive Manufacturing
(Laser Sintering) Technology

Superior - Quality Parts - Lower Costs

RMB Products is a world leader in additive manufacturing technology. Since its inception, RMB Products has been the gold standard for laser-sintered components. Having manufactured tens of thousands of flight-certified assemblies without a single failure in the field, RMB Products is the premier provider of laser-sintered functional hardware.

Laser sintering is a process that historically has been associated with rapid prototyping and manufacturing. Through the use of stringent process controls on every build, RMB Products has pioneered laser sintering as a production manufacturing process for aircraft ducting, shrouds, wire management trays, unmanned vehicle components and other nonstructural applications.

Laser Sintering Process

Laser sintering is a process in which complex plastic parts and assemblies are fabricated in a single process, one layer at a time. Parts are fabricated directly from a computer-aided design (CAD) file, allowing the manufacture of products to meet the exact design specifications created by engineers.

Fine plastic powder is loaded into containers in a heated chamber and rolled across a platform that incrementally lowers as each layer is processed. The laser sintering system slices the solid CAD model into thousands of horizontal layers, each of which is selectively melted by a CO2 laser. Each cross-sectional layer is successively melted on top of the previous layer to create a fully dense, solid part.

Each run of the process can yield multiple parts, all nested together within the build volume. Test coupons can be built alongside each part to nondestructively validate the parts’ mechanical or chemical integrity.

The sintered parts are now service-ready. Alternatively, as necessary, the parts may be post-machined, painted, bonded together and assembled with other hardware, resulting in a fully finished assembly.

Advantages of Laser Sintering

  • No tooling—Eliminates costly production tooling and die castings
  • Direct CAD model manufacturing—Manufactures complex parts with internal geometry directly from electronic data
  • Design flexibility—Integrates key features and eliminates costly secondary operations
  • Revision changes—Assimilates design changes quickly, without the need to retool
  • Part count reduction—Incorporates multiple, individual components into a single component; less inventory to manage, less procurement and contract management costs
  • Cost reduction—Optimized designs and reduced part count provides attractive savings opportunities compared with traditional manufacturing methods
  • Weight reduction—With the ability to optimize design features, products may weigh less while maintaining design intent for strength, flow and other characteristics
  • Product design optimization—Design a product with optimal features without traditional manufacturing constraints (allows for variable wall thickness, internal features, mounting brackets, etc.)
  • Short leadtimes—Quick-turn, low-volume alternative to tooled, multistep processed parts
  • Eliminates obsolescence issues—Addresses the growing industry problem of obsolescence for out-of-production spares in which tooling and materials are no longer available or are otherwise unaccounted for
