GE Renewable Energy and partners develop 3D printer for turbines

The 3D printer will allow large turbine components to be produced near offshore wind projects.

GE Renewable Energy has announced a research partnership with Fraunhofer IGCV and voxeljet to develop the world’s largest 3D printer for offshore wind applications.

As part of the project, the partners are developing a large-format 3D printer capable of producing sand moulds to cast metal parts for use in an offshore wind turbine nacelle.

The project is intended to streamline the production of key components of GE’s Haliade-X offshore wind turbine by printing moulds for cast components.

The three companies intend to launch the project in the third quarter of this year, with initial printer trials set to begin in the first quarter of next year.

GE Renewable Energy senior additive design engineer Juan Pablo Cilia said: “The 3D printed moulds will bring many benefits including improved casting quality through improved surface finish, part accuracy and consistency.

“Furthermore, sand binder jet moulds or additive moulds provide cost savings by reducing machining time and other material costs due to optimised design.”

GE claims the technology can reduce the time taken to produce patterns and moulds from ten weeks to two weeks.

The 3D printer is currently in the development phase. Its development is being backed financially by the German Federal Ministry for Economic Affairs and Energy.

Fraunhofer Institute for Casting, Composite and Processing Technology director Prof Dr Wolfram Volk said: “We aim to optimise the mould printing to avoid extremely costly misprints or even miscasts, to save on [the] binder and activator and to improve mechanical and thermal behaviour during casting.

“By developing a process that conserves resources as much as possible, we want to help to improve the environmental and cost balance in the manufacture of wind turbines.”

Earlier this week, GE Renewable Energy secured planning approval for an offshore blade manufacturing facility in Teesside, UK.
