Like it or not, design engineers need to get prepared for more environmentally oriented requirements. The newest evidence is an executive order from President George W. Bush that ramps by green requirements for the federal government. One of the six parts of the new order requires federal agencies to improve energy efficiency and reduce greenhouse gas emissions 3% annually through the end of fiscal year 2015. President Bush also wants agency acquisitions to reflect sustainable environmental practices, including acquisition of biobased, environmentally preferable, energy-efficient, water-efficient, and recycled-content products, and use of paper of at least 30% post-consumer fiber content. The requirement on bio-based materials is interesting. Design News plans to look intensively at the potential of bio-based polymers for engineering applications in the April 30 issue. Stay tuned.
An in-depth survey of 700 current and future users of 3D printing holds few surprises, but results emphasize some major trends already in progress. Two standouts are the big growth in end-use parts and metal additive manufacturing (AM) most respondents expect.
