New software algorithms have been shown to significantly reduce the time and material needed to produce objects with 3-D printers. Because the printers create objects layer-by-layer from the bottom up, this poses a challenge when printing overhanging or protruding features like a figure's outstretched arms. They must be formed using supporting structures—which are later removed—adding time and material to the process.

Provider of flexible and affordable 3-D modeling software for engineers, SpaceClaim, has announced the launch of the 2014 edition of SpaceClaim Engineer. The new release maintains the familiar interface and workflow of the prior editions while combining tools for manufacturing, advances in file compatibility, performance speed gains and improved collaboration.
While business operations have matured to help better commercialize new products, an important puzzle piece is missing. Companies must fill this gap to complete the big picture and accelerate innovation. That missing piece is science. Over the past few decades, process manufacturing industries adapted business operations to effectively manage transformational changes.
Richard Van As, a South African carpenter, lost four fingers from his right hand to a circular saw two years ago. He was unable to afford the tens of thousands of dollars to get a myoelectric hand, which detects a muscle's electric impulses to activate an artificial limb. He decided to build his own hand, made from cables, screws and thermoplastic, using only the Internet and a 3-D printer. He has since fitted 170 people with Robohands.
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.
