Projects, papers & conferences

At RAMLAB we are involved in multiple research projects. Over the years we have conducted many studies regarding optimizing the WAAM process and material properties. Leave us a message if you are interested in conducting research with RAMLAB. Get in contact.

RAMLAB Research Consortium

RAMLAB is an initiative of three founding partners: Port of Rotterdam, InnovationQuarter and RDM Next. To achieve its vision of manufacturing certified metal parts on demand through Wire Arc Additive Manufacturing, RAMLAB has built a powerful network of partners that provide hardware, software, and guidance on certification of the WAAM process. Also, RAMLAB has a growing list of end users that share the vision of Additive Manufacturing.

RAMLAB provides its partners easy access to an open innovation ecosystem in which the necessary resources and research on additive manufacturing are shared to the benefit of all. Close collaboration on joint projects accelerates the development and dissemination of relevant knowledge at a rate unattainable by a company operating on its own.

Research projects

  • WAAMTOP – Wire Arc Additive Manufacturing with Titanium for large Parts
    WAAMTOP is an AMable project and enables and optimises the deposition of large industrial titanium components with the use of Wire Arc Additive Manufacturing.
  • Grade2XL
    Grade2XL is a joint EU 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 allow to build strong and durable engineering structures. Read more.
  • AiM2XL
    AiM2XL is the first materials-centric research programme worldwide on direct metal deposition technologies, delivering fundamental knowledge on the relationship between processing conditions and the resulting WAAM microstructures and a collaboration between RAMLAB, TU Delft, UT Twente, TU Eindhoven and TU Groningen.
  • SMITZH
    SMITZH (Smart Manufacturing Initiative for the province of South Holland) is an initiative to stimulate smart manufacturing (industry 4.0) for the greater Rotterdam area. RAMLAB is involved in demonstration of WAAM across several industrial use cases, including: the world’s heaviest WAAM crane (WAAMhook), WAAM repair of mould and dies; a monitoring and control app for monomaterial WAAM processes.
