3D printing of bending-dominated soft lattices: numerical and experimental assessment

Serena Graziosi, Federico Maria Ballo, Flavia Libonati, Sofia Senna

This study aims to investigate the behaviour of soft lattices, i.e. lattices capable of reaching large deformations, and the influence of the printing process on it. The authors…

G-code generation in a NURBS workflow for precise additive manufacturing

Jesús Miguel Chacón, Javier Sánchez-Reyes, Javier Vallejo, Pedro José Núñez

Non-uniform rational B-splines (NURBSs) are the de facto standard for representing objects in computer-aided design (CAD). The purpose of this paper is to discuss how to stick to…

A multicriteria decision-making method for additive manufacturing process selection

Diqian Ren, Jun-Ki Choi, Kellie Schneider

Because of the significant differences in the features and requirements of specific products and the capabilities of various additive manufacturing (AM) solutions, selecting the…

Shrinkage behaviour of material extrusion steel 316L: influence of primary 3D printing parameters

Solomon O. Obadimu, Kyriakos I. Kourousis

The wide application of metal material extrusion (MEX) has been hampered by the practicalities associated with the resulting shrinkage of the final parts when commercial…
