Extending 3D concrete printing to hard rock tunnel linings : adhesion of fresh cementitious materials for different surface inclinations

, 2023
As an emerging automated construction technology, 3D concrete printing opens the opportunity for the construction of hard rock tunnel linings. However, very limited studies were carried out in this regard, especially the adhesion between freshly printed ...

Tensile Behavior of Chain Links Made of Polymeric Materials Manufactured by 3D Printing

, 2023
For reduced mechanical stress, some chains with links made of metallic materials could be replaced by chains made of polymeric materials. A lower weight and a higher corrosion resistance would characterize such chains.

METHOD TO CALIBRATE THE HORIZONTAL (CROSS-WEB) POSITION OF A FIDUCIAL MARK SENSOR

, 2023
This disclosure describes a new method to calibrate the cross‐web position of a fiducial mark sensor relative to the content that is printed upstream of the sensor. The method involves printing a pattern of horizontal and diagonal lines, using the sensor

Design and simulation of a large-scale 3D printing system using truncated tetrahedral tensegrity robot

, 2021
"We designed a new large-scale 3D printing system using a tetrahedral tensegrity robot with six struts connected with the cable. Three struts that form a bottom triangle are carbon pipes, and the other three diagonal struts are made of a linear actuator.

Laser Powder Bed Fusion of Alumina: Effects of Scanning Strategies on External and Internal Defects

Advanced Engineering Materials, EarlyView.
This study investigates how scanning strategies affect pure alumina in laser powder bed fusion. Linear 45° scanning yields uniform surfaces but high porosity, while the island‐concentric strategy provides higher density with through‐holes favorable for infiltration. Findings highlight pathways toward optimizing defect‐free alumina parts.
