From The Design Lab: An Insider’s Guide To Laser Sintering

While all additive manufacturing (AM) processes share the ability to create multifaceted parts with intricate features, each system has its own design guidelines to ensure accuracy and optimize part design for the build process and compatible materials. These design guidelines and trade knowledge are usually not shared externally, which can leave the average design engineer feeling adrift on a sea of 3D printing challenges. However, through years of experience, Stratasys Direct Manufacturing has gathered the most efficient design guidelines for one of the more popular 3D printing technologies: Laser Sintering. This article details a study undertaken by Stratasys Direct Manufacturing and the University of Texas (UT) at Austin which vetted tolerances for challenging LS design features such as minimum wall thickness, optimal build orientation for small to large features, and feature distances and areas in relation to part walls. Our goal is to make the information collected within the study well-known to the average design engineer and present working expectations for what LS can do, and therefore minimize errors and achieve consistently successful LS parts.

Precision Detector Conductance Definition via Ballistic Thermal Transport

This innovation could be applied in the development of bolometric detector array sensors. Goddard Space Flight Center, Greenbelt, Maryland The characteristics of a thermal detector, such as sensitivity, response time, and saturation power (or energy resolution), are functions of the thermal conductance of the detector to its cryogenic environment. The thermal conductance is specified to achieve a tradeoff among the highest sensitivity, allowed response time, and the desired saturation energy or power budget for the particular application. It is essential to achieve the design thermal conductance (within an acceptable variance) after a thermal detector has been fabricated. Otherwise, the detector will fail to achieve its desired functionality. In addition, the formation of a multi-pixel imaging array becomes difficult and costly when the design thermal conductance is not achieved with high post-fabrication yield.

A Robust Supply Chain: The Important Role Your Contract Manufacturer Can Play

Your complex device demands a robust supply chain. In today’s unsure environment, you need to know that your supply chain is available, flexible, and affordable when you need it. Establishing a strong and effective partnership with a contract manufacturer can ensure that you have the purchasing power and agility needed when the unexpected happens or design changes are needed. “A Robust Supply Chain,” our White Paper, outlines three things to look for in a contract manufacturer and three things you can do to ensure a smooth production process and an improved bottom line.

Thermal Spraying of Coatings Using Resonant Pulsed Combustion

This is a high-volume, high-velocity surface deposition of protective metallic and other coatings on surfaces. John H. Glenn Research Center, Cleveland, Ohio Thermal spray coating is not a new process. There are different techniques utilized that depend on the objective function of the coating, the environment to which the coated piece will be subjected, and the coating material used. In any application, quality is ultimately measured by how well the coating material adheres to the sprayed surface. This, in turn, is controlled by the velocity at which the coating material impinges on the substrate, the size of the molten coating particles, and the degree to which the coating material is prevented from chemically reacting while in a molten state.
