Additive Manufacturing in Construction

Research Summary Report A07

Wire and Arc Additive Manufacturing (WAAM) of Complex Individualized Steel Components


Unglaub, Julian, Associate Researcher, Institute of Steel Structures

Jahns, Hendrik, PhD Researcher, Institute of Steel Structures

Thiele, Klaus, Project Leader, Institute of Steel Structures


Project A07 investigates structural design, WAAM methods and component testing of complex, large-scale, individualized steel components. The objective is to connect conventionally manufactured steel components and semi-finished products with additively manufactured, complex steel components The Institute of Steel Structures develops a novel test method based on fill field strain data.

This test method considers potentially anisotropic component behaviour, surface topographies, geometric irregularities and residual stresses in addition to the relevant material properties.
