Will 'read-ahead' algorithms speed up 3D printing?

Our featured INSIDER story today showcased algorithms that allow 3D printers to anticipate motion and "read ahead" of its programming. The Michigan State University readers believe that the faster, more precise builds will allow 3D printers to create products twice as fast.

What do you think? Will 'read-ahead' algorithms speed up 3D printing?

Desktop Status

The purpose of the Desktop Status application is to collect processor, memory, and storage usages of a computer running the Microsoft Windows 7 operating system, and record these data with time stamps to files at a user-defined time interval. A graphical user interface (GUI) captures users' inputs and displays them on a plot for informational purposes. Microsoft Windows' Task Manager program, a prior art that is included in the Windows operating system, has the capability to collect processor and memory usages and display them on a graph, but cannot write the raw data values to files with time stamps at regular time intervals.

ScienceOrganizer: A Scientific Knowledge Management and Remote Experimentation Tool

The ScienceOrganizer system was designed to facilitate the work of geographically distributed NASA science teams by supporting the organization, administration, documentation, and execution of science projects and missions. The capabilities of ScienceOrganizer include the ability to conduct and monitor working experiments; locate, utilize, and publish experimental datasets; develop and share scientific software models; store scientific project information; document the scientific process; and co-visualize scientific data. Users access ScienceOrganizer through an intuitive Web-based interface that enables them to upload, download, and centrally organize project information including data, documents, images, and scientific records associated with laboratory and field experiments.

Knowledge Preservation Management

The Knowledge Preservation Management (KPM) system allows for the capture, management, and Web-based access of manufacturing operations information. KPM also captures retirees' knowledge via transcript-enabled video-taped interviews, and with video data-mining advanced search capabilities. Access to this information is available directly to the operator on the factory floor or in an office, providing a complete, on-demand knowledge management and training capability.

Development of Automated Structural Health Monitoring for Composite Overwrapped Pressure Vessels

Virtually all NASA spacecraft use composite overwrapped pressure vessels (COPVs) to reduce the weight disadvantage of metal pressure vessels. However, these composite structures are more susceptible to damage than metal PVs, are difficult to inspect, have large burst pressure variability, and are susceptible to stress rupture when maintained at pressure. Over the past few years, NASA's Johnson Space Center (JSC) White Sands Test Facility (WSTF) has developed novel analysis methods that show promise for assessing the structural health of composite overwrapped pressure vessels. These methods and industry standard methods have been integrated into specialized software for automated analysis, thus significantly increasing throughput to the point where real-time assessments of structural health may be determined. Adaptive analysis methods have also been developed to provide modal analyses at specified points in a structure's life, including loading, unloading, and dwells. Together, these enhancements increase the utility and ease of use for acoustic emission testing.

Key Considerations for Powertrain HIL Test

Safety, availability, and cost considerations can make performing thorough tests of embedded control devices using the complete system impractical. Hardware-in-the-loop (HIL) simulation is a real-time test technique used to test these devices more efficiently. During HIL test, the physical system that interfaces to an embedded control device is simulated on real-time hardware, and the outputs of the simulator mimic the actual output of the physical system. The embedded controller “thinks” it is in a real system. HIL simulation meticulously tests embedded control devices in a virtual environment before proceeding to real-world tests of the complete system. This application note covers recommended best practices for powertrain HIL testing.
