Additive solutions for aerospace

It is our challenge to design more sustainable propulsion systems for the aerospace industry - additive technologies and their advantages are key to contribute to sustainability.

The future of aerospace propulsion needs to be designed more sustainable - it is our challenge to move towards zero emissions and carbon neutrality
The increasing demand for CO2 reduction created a subsequent demand for eco-efficiency and alternative powertrain concepts
New materials and production technologies: Potential for new aerodynamic designs and reduced fuel consumptions

The future of aviation propulsion needs to be designed more sustainable

Setting new trends for the aerospace industry with large additive solutions like turbine rear vanes

We help you to move your application to additive manufacturing

The additive manufacturing process maximizes the design flexibility and allows the integration of additional functions - at no additional costs for extra geometry changes as no prior models or tools are needed. Geometries are no longer limited to the possibilities of traditional technologies.

In addition, with printing space as big as 500 x 500 x 500 mm, we offer serial production of large additive manufactured components with extremely complex shapes integrating more details and functions.

In-house development and validation expertise

Our central R&D team can set up and optimize your solution - for additive manufacturing as well as for casting processes.

Characterization of material properties
Support and consulting in the product development process
Additive Manufacturing oriented and compliant designs
Integration of additional functions and neighbour parts
Topology optimization and FEM simulation
Static and dynamic validation of components also under thermal boundary conditions
Leakage testing
Metallurgical analysis of components

High design freedom

Complex and extreme shapes from thick to hollow and thin-walled in one part.

High focus on the part functionality
Extreme shapes
Topological optimization and possibility to integrate lattice structure: Reducing weight and material
Maximal design freedom thanks to additive manufacturing

Benefits:
‒ Cost reduction as mating surfaces no longer need to be machined to tight tolerances
‒ Reduced lead time compared to functional surface creation via casting
‒ Cost-neutral feature
‒ Possibility to create closed cavities without the need of molding or post-processing

High functional integration

With product development and process expertise, we can integrate multiple single parts into one design.

Integrating six single parts into one design
Reduction of weldingto attach double-walled heat shiels for joint/assembly activities and process steps e.g. tooling or machining processes
Increased overall reliability due to single-piece production
Recuded leakage risk at the interface between different parts

Higher level of performance

Additive manufacturing enables functions such as optimized cooling and can be applied exactly where it is needed.

Increased air flow through the cylinders’ combustion chamber augments the engine power output
Reduced weight of the usually heavy doubled walls while achieving the thermal insulation required for optimal performance thanks to an air gap which is not feasible with traditional casting methods
Increased flexibility because of short production lead time
Cost advantage: not only within the geometry and performance of the application but cost savings through the reduction of process steps such as machining

Material properties

The tensile strength of additive manufacturing material is higher and the microstructure is finer than casting.

Density: almost no inner porosities (in AM evenly >99.5)
Depending on material and scope, AM can avoid HIP-treatment (cost intensive process step)
Microstructure is finer than cast ones: the tensile strength of AM material is higher
High repeatability in Additive Manufacturing

Big parts or high quantity

Part size or quantity - We think big! In our 500 x 500 x 500 mm printing space, big and heavy parts are possible as well as small parts in big volumes (part quantity in one print job).

Print job preparation

With state-of-the-art tools and proven expertise, our additive manufacturing team takes care of the print job preparation to make sure that the process can run properly.

Preparing the printer

We provide the printer with the right powder, clean the optic lenses and take care of the machine calibration.

Print job

The laser is directly melting the component layer by layer. The remaining powder can be reused after a dedicated sieving process.

Depowdering (automated)

Once the print job is completed, powder and component are separated automatically and individually.

Cutting (Wire EDM)

Wire EDM technology enables to achieve extreme accuracy.

Find the right technology for your project

Additive manufacturing or precision casting?

The choice for the perfect technology depends on the specific project requirements and needs. GF brings long-standing experience with similar component families from the casting process which is now built upon when offering additive solutions: of course at the same high quality level.

Concept

To start with a concept, we always take a look at cost efficiency, a component's lifetime, number of parts, geometry and part size.

Casting technology

Depending on your project, precision casting might be the right choice.

Additive manufacturing

Benefit from breathtaking speed and flexibility of the additive manufacturing process. With an expert team and certification, we develop and support your 3D-printing project.
