CFD model of laser additive manufacturing process of cylinders

Author: Tamsaout, T ; Kheloufi, K ; Amara, EH ; Arthur, Nana KK ; Pityana, Sisa L Date: Nov 2017 A theoretical approach based on a numerical simulation using experimental data is proposed as a contribution to the study of laser-based additive manufacturing by direct energy deposition (DED). The aim is to simulate the stages of layer-by-layer ... Read more
Laser based manufacturing of Ti6Al4V: A comparison of LENS and selective laser melting

Author: Arthur, Nana KK Date: Apr 2019 The laser engineered net shaping (LENS) system was used for the laser based manufacturing of a test geometry used to assess the performance of additive manufacturing systems. This system was preferred over a selective laser melting (SLM) ... Read more
Material characteristics of Ti-6AL-4V samples additively manufactured using laser-based direct energy deposition

Author: Willemse, MG ; Siyasiya, CW ; Marais, D ; Venter, AM ; Arthur, Nana KK Date: Feb 2023 Although additive manufacturing is fast gaining traction in the industrial world as a reputable manufacturing technique to complement traditional mechanical machining, it still has problems such as porosity and residual stresses in components ...

Microstructural Properties of Heat-Treated LENS In Situ Additively Manufactured Titanium Aluminide

Author: Tlotleng, Monnamme Date: Feb 2019 This study reports on the microstructure, phase identification and hardness property of the LENS-manufactured binary Ti-Al alloy which was achieved via laser in situ alloying. The in situ alloying method, using laser beam as an energy source, ... Read more
Performance evaluation and characterisation of EIGA produced titanium alloy powder for additive manufacturing processes

Author: Arthur, Nana KK ; Khodja, Malika ; Moller, Heinrich ; Rossouw, Pierre Date: Nov 2017 Metallic powders are widely used as the feedstock material for many additive manufacturing processes. Titanium alloys in particular are used in aerospace construction as an attractive alternative construction material due to the superior ... Read more
