A major aluminum lockout ended yesterday and the world’s first 3D-printed steel pedestrian bridge is planned to span a canal in Amsterdam.
Century Aluminum Lockout Ends
A month-long lockout at the fourth-largest aluminum smelter in the US ended Thursday after unionized workers voted to ratify a new five-year labor deal with Century Aluminum, the union said on its website.
The United Steelworkers of America Local 9423 and Century, controlled by Swiss commodities trade house Glencore Plc, resumed negotiations last week over a labor deal at the 244,000 metric-ton-per-year Hawesville, Ky., smelter.
Workers approved the deal by a 68% yes vote. The vote came after the more-than 560 union members rejected four previous tentative agreements on a new deal after the prior one expired on March 31.
First 3D-Printed Steel Bridge
The 3D-printed steel pedestrian bridge is planned to span one of Amsterdam’s historic canals.
Heijmans, MX3D, and Joris Laarman Lab are collaborating on the project. Joris Laarman Lab is designing the bridge and MX3D’s technology, which uses 6-axis robotic machines to create the steel structures of the bridge in mid-air. Heijmans told 3DPrint.com it will “contribute its knowledge of and experience in construction and technology to print the bridge.”
