  • Mig spot welding, although sometimes considered a tacking tool, has gained wide acceptance as a methodof joining which is competitive with riveting and resistance spot welding. In some applications, it hasreplaced continuous welding methods as it provides reduced welding costs, reproducibility, and adequatestrength for the service requirements and requires minimum operator skill. Mild steel, stainless steel andaluminum are very commonly welded with this method

  • Since the cost of manufacturing a custom train part on a small-scale 3D printer is only $25, Kendrick’s niche market of loyal consumers can afford to manufacture their own train parts -- no investment in factory-scale production is needed. Imagine if a model train enthusiast purchased Kendrick’s electronic blueprint and tried to produce the stainless steel train cowcatcher (shown in the figure) in a factory. The high cost of setting up a factory infrastructure would be well out of the reach of the average consumer.

  • Carsharing (or short-term auto use) provides a flexible alternative that meets diverse transportation needs across the globe, while reducing the negative impacts of private vehicle ownership. Although carsharing appeared in Europe between the 1940s and 1980s, it did not become popularized until the early 1990s. For nearly 20 years, there has been growing worldwide participation in carsharing. Today, carsharing operates in approximately 600 cities around the world, in 18 nations, and on four continents. Malaysia is operating a carsharing pilot, with a planned launch in late-2006.
