Key Information

Grade2XL: Functionally Graded Materials for Extra-Large Parts

•    EU funding: € 7,91 Million
•    Total budget: € 9,75 Million
•    Duration: 48 months [March 2020 – Feb 2024]


Grade2XL is a joint development programme aligning partners along the value chain to foster the rapid development of WAAM materials and process. Grade2XL will deliver multi-material products of superior quality and performance. The high printing rate of WAAM, combined with the ability to control material properties down to the nanoscale, will enable building strong and durable engineering structures.
The Grade2XL project, funded by the programme Horizon 2020, will demonstrate the potential of multi-material wire arc additive manufacturing (WAAM) for large  structures ~1 to >10 m length. Grade2XL will strengthen Europe’s capacity to drive manufacturing innovation globally and withstand growing competition from Asia.


Grade2XL will deliver a multi-material, high throughput WAAM system, removing the technological barriers that hinder the application of WAAM, on three levels:

  1. Material level: functionally graded (multi)materials will be achieved by controlling the two main factors governing the material properties: the chemical composition and the thermal
  2. Process level: high WAAM productivity will be achieved using multiple wire deposition systems. The productivity will increase from typically 2 kg/h to 5 kg/h, which can double when a dual robot configuration is used. In-line contactless inspection will ensure first time right quality and facilitate qualification.
  3. Life cycle or system level: challenging applications will demonstrate the lifecycle benefits of WAAM multi-material devices and in-line process control.

Role in project

UGent focuses on the study of the microstructure of the materials and on the topology optimization.
