Penetrated surface characteristics of cement - mixed sand in powder bed 3D printing
Powder bed 3D printing is an additive manufacturing process that combines powder particles by selectively depositing a liquid activator on a powder bed. Sand molds for high-resolution casting can be realized as a high-quality green body via powder bed 3D

Powder bed 3D printing with quarry waste
Abstract With 3D printing, material consumption can be reduced: It allows to place material only where needed, therefore structurally optimized building parts or formworks can be printed. Currently this technique uses an epoxy based resin to glue layer by layer an inert sand bed.

Powder Bed Monitoring Using Semantic Image Segmentation to Detect Failures during 3D Metal Printing
Monitoring the metal Additive Manufacturing (AM) process is an important task within the scope of quality assurance. This article presents a method to gain insights into process quality by comparing the actual and target layers. Images of the powder bed were captured and segmented using an Xception–style neural network to predict the powder and part ...
