The Influence of the Material Type and the Placement in the Print Chamber on the Roughness of MJF-Printed 3D Objects

open access: yesMachines, 2022
This paper describes a surface-roughness study performed on samples manufactured additively using the Multi Jet Fusion (MJF) technology. The samples were divided into three groups based on the material used in the process: polypropylene (PP ...

Injection Moulding into 3D-Printed Plastic Inserts Produced Using the Multi Jet Fusion Method

open access: yesMaterials, 2023
Most injection-moulded plastics are injection moulded into moulds made from conventional materials such as steel or aluminium. The production costs of the mould are considerable. 3D printing from plastic can be used for injection moulds to save these costs. This article deals with injection moulding into a 3D-printed plastic mould. The injection insert

Production cost model of the multi-jet-fusion technology

open access: yesProceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2019
The paper presents a model of the production costs of the multi-jet-fusion technology that is based on a model of production costs of the selective laser sintering technology. The model is developed using the methodology of analysis of the event-driven process chain, which consists of modeling, batch assembly, setup, building, removal, and blasting ...

Wgamma and Zgamma production at the LHC in NNLO QCD [PDF]

open access: yes, 2015
We consider the production of $W\gamma$ and $Z\gamma$ pairs at hadron colliders. We report on the complete fully differential computation of radiative corrections at next-to-next-to-leading order (NNLO) in QCD perturbation theory.

Higgs + Multi-jets in Gluon Fusion

open access: yes, 2016
We present a detailed phenomenological analysis of the production of a Standard Model Higgs boson in association with up to three jets. The Higgs is produced via gluon fusion, which is an irreducible background to the vector boson fusion mechanism. We calculate the next-to-leading order corrections in QCD in the limit of an infinitely heavy top quark ...

Overview of the JET preparation for deuterium-tritium operation with the ITER like-wall [PDF]

open access: yes, 2019
For the past several years, the JET scientific programme (Pamela et al 2007 Fusion Eng. Des.82 590) has been engaged in a multi-campaign effort, including experiments in D, H and T, leading up to 2020 and the first experiments with 50%/50% D–T mixtures ...

Numerical investigation of fiber orientations and homogeneity in powder bed fusion of fiber/polymer composites

open access: yesVirtual and Physical Prototyping, 2023
The packing characteristics of fiber/polymer powder in powder bed fusion additive manufacturing exhibit a high correlation with the mechanical behaviours of printed composite parts such as homogeneity and anisotropy.
