Thermal process modelling of lattice structures during selective laser melting process

As a type of powder-bed-based Additive Manufacturing (AM), Selective Laser Melting (SLM) is widely used for building metallic lattice structures. However, during SLM process, geometrical imperfections and defects, such as strut over-sizing or under-sizing, typically exist in components due to overheating, which strongly influence their...

Fatigue Crack Propagation in Additively Manufactured and Functionally Graded Inconel 718

Additive Manufacturing (AM), commonly known as 3D printing, exemplifies the recently emerging processing methodologies that aim to substitute the conventional routes, such as to produce parts with complex geometries and eliminate expensive tooling. AM also allows high degree of freedom and rapid prototyping for functional part optimization. This...

Fatigue Behaviour of functionally graded Inconel 718 manufactured by selective laser melting

Functionally graded materials (FGMs) represent a new class of materials that consist of graded compositional and microstructural patterns allowing to tailor properties. Additive manufacturing (AM) or more commonly known as 3D-printing offers a paradigm shift in FGMs and engineering design due to its ability to produce components with complex...

The set-up of an integrated working concept factory using metal additive manufacturing

In order to produce more complex parts, additive manufacturing is on the rise as a competitor for more conventional manufacturing methods. Unfortunately, additive manufacturing often produces products with a less desirable tolerance and surface roughness. Subtractive methods require special tooling and fixtures for each part design and typically...

A Knowledge Based System to Support Design for Selective Laser Melting

Modern Computer Aided Design/Engineering can assist in the design of highly optimized engineering structures. Such structures allow for a significant reduction on the strain of resources across the product life cycle, where the potential for weight reduction is most beneficial for the aerospace industry. However, their production is currently...
