casting 3D printing for foundries.

The company uses direct metal laser sintering (DMLS) as well as 3D printing of sand molds for rapid casting. Andreas Steinbronn, Head of Parts Management at GRATZ, explains why 3D printing has led to immense advantages in manufacturing speed, cost-effectiveness and a whole new, disruptive approach to design. DMLS is fast but expensive; in contrast, 3D sand molding followed by metal casting is

Sand 3D Printer What Exactly Is It? All3DP

Sand 3D Printing of Concrete Forms. An exciting new application for sand 3D printing is to print complex shapes for architectural design. Researchers at ETH Zurich have been researching how to use a sand 3D printer to create molds for concrete. Concrete can make up as much as 80% of commercial structures today. With this much material demand

New 3D sand printer is used for the first time in European

The new 3D sand printer is to be used in particular for on-demand production of complex spare parts, prototypes and very small and pilot series. However, the new machine will not only be used in the Blöcher foundry for the rapid production of moulds for the production of spare parts and small series made of aluminium. The robot-assisted system is also used when urgent replacements are needed
