Ok, so it's jumbled, but that's the point. We've heard so much about the use of composites in the automotive sector and in aerospace, even with large-scale boats and yachts, but not so much in trains. Improved access to more efficient and cost-effective mass transportation is equally as important as alternative energy sources and lightweighting vehicles as part of green energy strategies. This is a cool development. Any big deals yet for the technology?
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.
