Castings Equip Amazing Work in Chile
Astronomers from all over
the world share resources in the Atacama desert of Chile, the driest place on the planet. Its lack of airborne water vapor is among the factors that make this region one of the best places for telescopes to view the night sky, and it is home to many of them. The technology employed by the

WE HAVE ONE IN DEVELOPMENT
European Southern Observatory at Paranal in Chile is under con- tinuous development. A telescope dubbed the VLT (for “very large”) uses cryogenics, lasers and other specialized equipment to enable unprecedented feats of astronomy. New metal castings on the VLT include two 3D print-enabled compo- nents. Using a printed thermoplastic pattern, German fi rm voxeljet AG produced a complex, investment cast sensor arm for use with the telescope’s MUSE instrumentation. Metalcaster ACTech GmbH invest- ment cast a ductile iron “spacer” component using a laser sintered pattern. A team of astronomers prepares to begin MUSE Science Verifi cation observations as the new instrumentation debuts. The MUSE instrumentation is
on its second generation, and was recently installed on the VLT, which has now undergone a series of successful tests performed to ensure its operation. “It enables us to see a greater field, allowing the study of multiple objects at one time,” explained Cristian Esparza, VLT telescope and instrument op- erator. The culmination of approxi- mately 10 years of research and development, MUSE exponentially increases the VLT users’ ability to study everything from black holes to entire galaxies. —Denise Kapel, Senior Editor
