Rayvatek, a metal additive manufacturing
technology and service company, has announced “breakthrough” solutions in
aerospace materials developed through a collaboration with SLM Solutions. The
company says that aerospace continues to be one of the fastest-growing fields
for the application of 3D printing globally.
In terms of weight reduction, SLM
Solutions’ selective laser melting technology can be used to manufacture
integral thrust chambers that combine multiple parts into a single part. 3D
printed lattice structures and internal cooling channels contribute to
improvements in part quality, weight reduction and fuel saving according to the
SLM says that its technology is useful for
small batch production of complex parts, enabling cost reductions and tool-free
production, shortening the development cycle.
Through the use of an SLM 280 3D printer,
Rayvatek is able to manufacture injectors of different sizes through a single
manufacturing process, accelerating testing and development and enabling more
efficient injection of oxidiser into the combustion chamber, which increases
thrust power for the launch vehicle.
3D printing also means that flow
distributors can be printed in one piece, rather than assembled in multiple
pieces, which Rayvatek says helps to achieve the goal of smooth and even
distribution. The SLM 280 can also fabricate hollow parts for impellers,
reducing the weight and the moment of inertia of the product, improving
efficiency and reducing energy consumption.
A Rayvatek spokesperson said: “We are
delighted to cooperate with SLM Solutions, a leading metal 3D printing
equipment manufacturer. Combining SLM's high-precision printing capabilities
with Rayvatek's experience and expertise in the space industry allows us to
develop and produce high-quality space components and expand our offerings to a
wider range of sectors, including aerospace, maritime transport, electric
vehicles, motorcycles, bicycles, heavy machinery and moulds, and energy.”
