3D Printing and the Future of Manufacturing

3D printing is transforming the manufacturing industry in big ways. From realized design freedom to supply chain efficiencies, 3D printing is contributing largely to the recent upswing in reshoring manufacturing in North America. Read the latest white paper from Stratasys Service Bureaus to learn how 3D printing will continue to transform the industry in the coming years.

Will "4D" materials catch on?

This week's Question: While 3D printing has still not yet reached the mainstream, MIT and other researchers are performing primary tests on the next design dimension. 4D printing, a self-assembly design process, enables the production of composite materials that react and change shape in predictable ways when exposed to external elements such as water. A printed rear wing, for example, would have the ability to transform its aerodynamics during a downpour. Autonomous pipes, too, could expand and narrow based on flow. Read more »

Greater Heat Stress From Climate Change Could Lower Dairy Productivity

In 2010, heat stress is estimated to have lowered annual milk production for the average dairy by about $39,000, totaling $1.2 billion in lost production for the entire U.S. diary sector. Additional heat stress from climate change is expected to lower milk production for the average dairy by 0.60-1.35 percent in 2030 relative to what it would have been in the absence of climate change.

SNAP Households Must Balance Multiple Priorities To Achieve a Healthful Diet

Participants in USDA’s Supplemental Nutrition Assistance Program (SNAP) value nutrition as much as other consumers, but their attempts to balance nutrition goals with competing constraints—time, distance to grocery stores, and money—may make it harder for SNAP shoppers to make healthy choices.

Slow Sales Growth and Increased Company Acquisitions Impact U.S. Food Retailing

Food and nonfood grocery sales by the 20 largest U.S. grocery retailers totaled $449.3 billion in 2013—63.8 percent of U.S. grocery sales. This share is down from their sales share peak of 65.1 percent in 2008, but is the first increase since the 2007-09 recession. The four largest grocery retailers accounted for 36.4 percent of total grocery sales in 2013.

Higher Corn Returns Changes Corn Farm Dynamics

Changes in the returns to corn production are examined over 1997-2013 period using data from ERS cost and return accounts and the corn versions of the Agricultural Resource Management Survey (ARMS).

9 questions to ask when specifying a slewing ring bearing

In applications where a bearing must support a rotating structure (e.g. cranes, radar, tank turrets), premature failure can put people and equipment at risk. Designers choosing a slewing ring bearing for such applications should consider many factors, such as the bearing’s support structure, mounting (including bolt strength, tensioning and hole patterns), installation, and even storage. A new white paper from Kaydon Bearings, an SKF Group company, details nine key questions to ask when specifying a slewing ring bearing.
