Metal Additive Manufacturing Conference - MAMC 2026

The industrial use of additive manufacturing requires not only stable processes but also a deep understanding of the relationships betweenprocess parameters, material behavior, and part quality. This presentation demonstrates how data-driven methods and advanced process monitoring can be applied to predict critical quality characteristics during manufacturing. Drawing on current research...

Hard magnetic materials are essential for various applications, including green energy technologies such as renewable energy systems and electromobility. Additive manufacturing has emerged as a promising method for fabricating hard magnetic materials, offering design flexibility and scalability. While most research has concentrated on rare-earth-based NdFeB magnets, few studies have also...

Mechanical property verification for laser powder bed fused (LPBF) Ti-6Al-4V traditionally relies on machined witness specimens and destructive tensile testing. Indentation plastometry offers a faster, less material-intensive alternative by extracting stress-strain behaviour from controlled surface deformations via inverse numerical analysis. However, implementing this methodology for additive...

Retained austenite (RA) is known to influence the printability and resulting microstructure of additively manufactured (AM) tool steels, particularly under low preheating conditions where thermal gradients and cooling rates are high. This study investigates the effect of preheating temperature and selected laser powder bed fusion (LPBF) process parameters on the retained austenite content of a...

Arc-based Directed Energy Deposition (DED-Arc) provides significant potential for large-scale additive manufacturing, yet industrial adoption remains restricted by the underutilization of multi-axis system kinematics and a lack of comprehensive data for robust process control. This study investigates the complex interdependencies between torch orientation, stick out length, and welding...

Parameter selection in wire arc Directed Energy Deposition (wa-DED) is inherently complex due to the large number of interdependent process variables. For weaving strategies in particular, no straightforward empirical rules exist across varying deposition rates. This makes trial-and-error approaches costly and unreliable. This work presents a systematic, geometry-based derivation of key...

Metal Additive Manufacturing (MAM) via Laser Powder Bed Fusion (L-PBF) has become an established production technology, ranging from rapid prototyping to the serial production of complex components. However, the increasing diversity of machines, materials, and process configurations creates significant challenges for quality assurance and process stability.
To achieve First-Time-Right or...

Non-destructive testing (NDT) plays a critical role in the quality assurance of additively manufactured components. Due to the layer-wise manufacturing process, additive manufacturing can introduce process-induced defects such as porosity, lack of fusion, and residual stresses, which may significantly affect mechanical performance and structural integrity. NDT methods ideally enable the...
