Wire and Arc Additive Manufacturing (WAAM) is one of the fastest additive manufacturing techniques in terms of deposition volume, making it particularly well-suited for the construction industry due to its ability to produce large components efficiently.

However, the significant energy input required in WAAM poses a major challenge, which becomes even more pronounced when fabricating hollow parts—a common feature in steel structures used in construction.

At ConstructAdd, our PhD student Saber Zolfaghari, alongside SITEC Lab Staff Ismail Kurt, is working on innovative solutions to address these challenges.

By developing novel toolpath planning and deposition patterns, they aim to enable the creation of complex hollow steel components using WAAM, pushing the boundaries of Additive Manufacturing in Construction Industry.
