Foundry goes 3D printing

Additive manufacturing opens up new potential for foundries

In a direct process, foundries extend their value creation chain. Due to the nature of the process, conventional casting processes reach technological limits. Additive manufacturing allows boundaries to be crossed and new bionic structures to be created with hitherto unknown geometric freedom - especially when lightweight construction and functional integration are required. Components are not only able to be manufactured in a completely additive manner - also cast parts can be supplemented layer by layer.

Printed filigree sand cores

In indirect processes, the casting process itself benefits from the additive technology. Without rework, 3D printers create wax or plastic models for investment casting as well as sand moulds and cores for metal casting. Through layer by layer application of quartz sand, which is selectively bonded with a binder, it is possible to produce filigree cores with a high degree of precision and almost without any geometry.

Showcase of the latest developments

Whether in model and mould construction, core production or direct metal printing - additive manufacturing opens up untapped potential for foundries and their suppliers. At GIFA 2019, foundries and subcontractors will be demonstrating in presentations and at the stands how a traditional branch of industry is able to integrate innovations and use them successfully.
