Weight Reduction is an exceptional attribute on many SLS applications, particularly within the aerospace industry. The SLS process provides engineers with the ability to incorporate differing cross-section designs and integrate components into unitized structures – saving weight over conventional multi-part assemblies. Many applications making use of Solid Concepts Nylon-11 based materials (NyTek-1100 series) have been able to convert what were extruded, cast or mandrel bent aluminum parts into SLS manufactured “drop-in” components – realizing a 30% to 50% weight reduction.
Functional Parts that are durable, heat and chemical resistant result from utilizing the SLS process. These par ts can be readily joined mechanically or with adhesives. Secondar y operations may include sealants, coatings, and metallization through vapor deposition or electroplating processes. To get the most out of SLS technology, par ts should be specifically designed for the process to make full use of the unique benefits of additive layer manufacturing. Your design ef for ts can now focus on functionality, allowing for more robust designs with fewer restrictions.
Parts Consolidation is a natural by-product for companies that design for the additive manufacturing process. Multiple piece-parts can be designed as an integrated structure that leverages the benefits of SLS by combining numerous components into a single unitized assembly. This reduction in part numbers will save assembly time and reduce assembly weight.
Repeatable Process Control amongst machines is critical to building consistent Selective Laser Sintered parts and prototypes. The structure and properties of parts made by the SLS process depend on both process parameters and powder characteristics. Solid Concepts has implemented proprietary process controls and procedures to assure consistent handling and recycling of powder materials for consistent build quality. These parameters include material traceability, monitoring the mixing and testing of powder prior to builds, monitoring the thermal process during the build, and post-process testing of tensile bars to assure the quality and repeatability of every SLS build.
Direct Digital Manufacturing (DDM) is the SLS process for rapid manufacturing of functional parts direct from digital data without tooling. DDM eliminates the cost of creating, maintaining, storing and transporting expensive tooling while providing you with a virtual, on-demand inventory that's just a telephone call away. DDM designed SLS components can often be implemented as a “drop-in” parts replacement technology. DDM can also be cost effective if a design is subject to change during production and avoids the costs and delays needed for additional tooling.
Production Aerospace Expertise is critical to many of our customers. Solid Concepts has assembled an exper t team with critical SLS process knowledge for aerospace applications using DDM for production flight hardware. If you have an aerospace application, you’ll want to call on the experience of our SLS Business Development Manager, and see your project through with one of our experienced Aerospace Project Engineers.
