Adobe announced, in January, the availability of Acrobat 3D, which allows users to convert a wide range of 2D and 3D CAD models to Adobe PDF. Although the size of the PDF file definitely depends on the size of the native CAD file, Adobe says that the PDF file will be significantly smaller. Using Acrobat 3D, users can view, markup and reline a 3D model in an Adobe PDF file, cut cross sections, measure the 3D design and add security measures to the document. A 3D toolkit that ships as part of Acrobat 3D allows users to also create animations, high-quality vector and raster images, and materials and lighting in a 3D model, then output it to Adobe PDF. Acrobat 3D also enables users to "turn on" added functionality in the free Adobe reader for a specific Adobe PDF file. For example, when you send out a 3D PDF for review, users can leverage all of the Acrobat commenting tools on both 3D text and 3D models, including cross sections, measurements, etc. Adobe 3D supports the major CAD applications, including CATIA V4 and V5, SolidWorks, UGS NX, and PTC Pro/ENGINEER. The software is priced at $995, with upgrade prices for existing users of Acrobat 6.0 and 7.0 Professional. For more information, go to http://rbi.ims.ca/4915-534.
Producing high-quality end-production metal parts with additive manufacturing for applications like aerospace and medical requires very tightly controlled processes and materials. New standards and guidelines for machines and processes, materials, and printed parts are underway from bodies such as ASTM International.
Engineers at the University of San Diego’s Jacobs School of Engineering have designed biobatteries on commercial tattoo paper, with an anode and cathode screen-printed on and modified to harvest energy from lactate in a person’s sweat.
