At TCT Show + Personalize in the UK at this end of this month, Renishaw will be highlighting an upgrade for their AM250 3D printing and laser melting machine. The upgrade, PlusPac, can be ordered with new machines, or existing ones can be retrofitted. The upgrade offers new optical control software, a gas knife lens window protection system, and high capacity gas filtration system. At the show they will also highlight the Renishaw Equator, a gauging system that uses a 3D scanning probe, and they will exhibit their vacuum casting systems.
