Additive Manufacturing

The ISQ AM (Additive Manufacturing) laboratory comprises several additive manufacturing technologies, namely powder bed fusion, wire arc (MIG/MAG and plasma) and laser metal deposition. The laboratory is equipped with a set of post processing techniques for the final treatment of the produced components, and it also includes a set of software tools that enables the activities of design and generative design ( DfAM ), trajectory generation and thermomechanical simulation.

This laboratory allows supporting industrial innovation, particularly in the simulation of additive manufacturing processes, as well as the qualification and certification of processes and operators. In this field ISQ is an Authorised Nominated Body for Additive Metal Manufacturing (AM ANB) by the certification and qualification system of the EWF (European Welding Federation), ensuring that the qualification system is correctly implemented. Additionally, ISQ is also an AM ATB (Approved Training Body) and is therefore an Approved Training Centre for Additive Metal Fabrication to develop training activities within the scope of the EWF Training and Qualification system.
