Method for Decreasing Additive Manufacturing Build Times Using Arrays of Multiple Deposition Heads

3D printing several parts simultaneously enables increased speed for mass production. NASA’s Jet Propulsion Laboratory, Pasadena, California Additive manufacturing (AM, also informally known as 3D printing) is a relatively new process for fabricating net- shaped parts from a computer-generated drawing. The inherent problem with using AM in mass production is the slow build times for each part. Because parts must be built layer by layer, the build time cannot be dramatically increased. The build time is limited by the physical melting and consolidation of plastic or metal, which cannot be dramatically speeded up, and the velocity of the build head, which is limited by the mechanical motion mechanism. One solution to the inherently slow build times is to replicate the building head, while replicating as few of the other machine components as possible. Utilizing this technique, the fabrication time per part can be reduced by the number of simultaneous building heads, which may make the AM process suitable for some mass production.

Product of the Month: October 2015

National Instruments, Austin, TX, has released the PXI-based Wireless Test System (WTS) that combines a PXI vector signal transceiver (VST) and multicore processing technologies to offer a single platform for multi-standard, multi-DUT, and multi-port testing. When used with test sequencing software, such as the TestStand Wireless Test Module, manufacturers can test multiple devices in parallel. Fullduplex RF ports and wideband RF instrumentation support current and future wireless standards such as LTE-A to 802.11ac and Bluetooth LE. The SCPI interface allows remote automation over Ethernet and smooth integration into existing manufacturing lines. Other features include up to 200-MHz instantaneous bandwidth, 65-MHz to 6-GHz frequency range, and SCPI interface via Ethernet. For Free Info Visit http://info.hotims.com/55594-120

ISO 13485 - The proposed changes and what they mean for you

BSI’s latest white paper introduces the expected updates to ISO 13485, the quality management system standard that complements product specific directives. Many of the changes are best practice and can be immediately addressed, hopefully resulting in a much easier transition when the final version of the standard is ultimately published.
