3D printing benefits castings firm

UK castings solutions specialist, Grainger & Worrall has enhanced its portfolio of rapid prototyping technologies by investing more than £500,000 in an S-Print HHS sand printer.

The printer utilises a high heat strength (HSS) binder paired with low expansion sand mix to create highly intricate core structures, directly from CAD data.

The tool-less casting technology also provides greater design freedom by enabling the construction of previously unfeasible internal geometry, when compared with directly-milled sand moulds.

Compared to printed furan technology, the HHS sand print process is optimised to produce up to 250% stronger cores that are able to maintain even greater geometric stability throughout the casting procedure.

Edward Grainger, Grainger & Worrall's director, said: "Our latest investment will further enhance our ability to offer customers, across the automotive, motorsport and aerospace sectors, greater benefits in terms of time, cost and performance.

The addition of the S-Print HHS sand printer will allow us to continue to deliver ground-breaking innovation for our clients, now and in the future."
