The new Allen-Bradley CompactLogix controller from Rockwell Automation (www.rockwellautomation.com) offers a SERCOS interface, EtherNet/IP connectivity and a powerful processor. Controlling up to four axes of motion, the 1768-L43 is designed for applications requiring speed, motion synchronization and information-sharing capabilities in a small, modular footprint. It combines motion and sequential control into a single, integrated multitasking platform and supports a full range of networks including DeviceNet, ControlNet and EtherNet/IP. The controller uses the same Logix control engine, motion, networking technology and communications services as the A-B ControlLogix and SoftLogix controllers.
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.
