Experimental and numerical determination of the fatigue notch factor in as‐built wire arc additive manufacturing steel components

Fatigue &Fracture of Engineering Materials &Structures, Volume 47, Issue 11, Page 4372-4389, November 2024.
Abstract Parts manufactured by wire arc additive manufacturing (WAAM) are characterized by a peculiar surface morphology, namely, surface waviness, that negatively affects the fatigue performance. To exploit the full potential of WAAM and minimize the need for postproduction work, it is crucial to utilize the components in the as‐built state.

Toward a Standardized Approach for Characterizing β‐Fleck Defects in Titanium Alloys

Advanced Engineering Materials, Volume 26, Issue 16, August 2024.
 This work presents a new way to quantify β‐fleck defects in titanium alloys. The simple method involves a combination of heat treatment and metallography to reveal β‐flecks using readily available tools such as optical microscopy. With open‐source image processing software, β‐flecks are identified over a large area allowing metrics to be quantified ...

Is it safe to give birth with an activated implantable cardioverter–defibrillator: A multicentre observational study

BJOG: An International Journal of Obstetrics &Gynaecology, Volume 131, Issue 9, Page 1290-1295, August 2024.
Abstract Objective Data and guidelines are lacking, so implantable cardioverter–defibrillators (ICDs) are often deactivated during labour to prevent inappropriate shocks. This study aimed to ascertain the safety of an activated ICD during labour. Design An observational study was performed. Setting Dutch hospitals.

Variable Layer Heights in Wire Arc Additive Manufacturing and WAAM Information Models

Machines
In Wire Arc Additive Manufacturing (WAAM), variable layer heights enable the non-parallel or non-planar slicing of parts. In researching variable layer heights, this paper documents printing strategies for a reference geometry whose key features are non ...

A method for analyzing the kinematic influence of a robot on the WAAM process

The International Journal of Advanced Manufacturing Technology
This article propose a method to analyze the kinematic behavior of a robotic cell during a tool path following. This methodology is applied to a WAAM robotic cell to study the manufacturing of single-wall, tubing-type parts with a robotic WAAM process. Initial feedback shows deposit defects.
