While 3-D printing empowers people to create amazing objects once unimagined, it also raises red flags on the legal concept of strict product liability, according to a Stanford Univ. law professor. Nora Freeman Engstrom published her research exploring how 3-D printing is poised to challenge the American litigation landscape. 3-D printers can produce elaborate 3-D products of almost any shape, working from designs on a computer screen.

Researchers at Georgia Tech are helping the U.S. military make key changes in how aircraft electronic systems, called avionics, are produced. The effort focuses on modifying the design of avionics software, especially the ways in which it interfaces with an aircraft's hardware and other software. The work is part of the U.S. Navy's Future Airborne Capability Environment (FACE) project.
An engineer in Finland has designed a new evaluation model that allows developers to determine how fatigue sets in with various welded steel materials. By considering the differences between traditional welds and structural joining technologies and newer more advanced methods, he model allows for the development of lighter structures, and as a consequence, more energy-efficient ships.
A collaboration of several government and academic research organizations are hard at work on a design and manufacturing concept called “model-based design and verification”. Instead of building prototypes and discarding them, manufacturers would conduct virtually all of the design, testing, error identification, and revisions on a computer up to the point of commercial production.
