Weeks later, we're still talking about Local Motors and the Strati that took shape at IMTS 2014 in Chicago. Local Motors posted that their intentions were to change the way people think about the future of manufacturing (above). What did this carbon fiber and thermoplastic car mean for those of us who make a living in metal?

Plastics Play Well With Others

For starters, the Local Motors build highlighted how new technologies can be integrated with traditional techniques like CNC milling. Machine shops can also use polymer-based 3D printing as an intermediate step on the way to a final metal part. The August issue of MetalForming Magazine shows how 3D printing with thermoplastics is being used to make tools and form blocks for sheet hydroforming. When used in combination, the process provides major time and cost savings versus press-brake forming, and allows machines shops to accept small orders and still turn a profit.

Better and More Affordable Metal 3D Printing

3D printing using metals has been possible for more than a decade, though high initial costs and concerns about the quality of finished products have hampered widespread adoption. Still, equipment sales increased in 2013, and startups like MatterFab are working to build less expensive machines that would be accessible to a wider audience.  Meanwhile, both corporations and think tanks are working to advance the alloys and metal powders that the machines use to create metal parts.

Do you agree that 3D printing will change our minds about the future of manufacturing?  If so, how would it impact your business?
