Key factors towards a high-quality additive manufacturing process with ABS material
2019
Abstract Additive Manufacturing technologies have gained a lot of popularity during the past years. The current challenge being the transition of this manufacturing technology from prototype oriented towards mass production. In order to achieve this, fabrication times and mechanical parameters must be improved. This paper aims to identify which are the parameters that have the highest influence on parts obtained with fused deposition modeling (FDM) technology from ABS material. In addition, this study identifies which are the most accurate methods to test the mechanical properties of FDM parts while still respecting ASTM standard for testing the tensile properties of plastics. It was found …
Improvement of learning quality in manufacturing technology: a case study
2017
The paper presents the initial part of a study designed to understand the place of the present generation of engineering students in the global picture of their working life. The education represents an inestimable good that accompanies peoples through their existence. Higher education is the place were teenagers with different profiles modelled by their families, studies; experiences and so on come to meet, in most cases, the final education platform before employment. In light of this the higher education has the major role of prepare the students with the knowledge and skills appropriate to the labour market. That means with the knowledge and skills they need and their future employers a…
Ankle Foot Orthoses with Wire Insertion
2013
The objective of the work is to present some researches regarding the virtual modelling of external medical devices with wire insertion. Ankle foot orthoses are used to correct and prevent different disfunctions of the human body and also in athlets recovery. The research is motivate by the problems appeared using this medical devices: durability issues, patient confort, manufacturing costs, lightweight, flexible access to shoes, inexpensive, readily available. These issues depends of the wey design, manufacturing technology, materials used, patient behavior, skills manufacturer. Wire insertion in polypropylene is a new approach of orthoses materials.
Study regarding the influence of material type on economic objectives in MEx fabrication
2021
Material Extrusion has been used extensively as an additive manufacturing technology for a variety of applications like visual models, functional prototypes, tooling components, patterns for castings, and final parts. The current research paper proposes a study on the material type influence on economic objectives in material extrusion fabrication of complex assemblies. Three economic objectives have been analysed, namely, estimated fabrication time, material usage and material cost, whilst two commercial additive manufacturing machines have been considered for the simulation. Cura and ZSuite slicing software were used for the generation of Gcode and project files. Five filaments were selec…
Lobster eye optics for nano-satellite x-ray monitor
2011
The Lobster eye design for a grazing incidence X-ray optics provides wide field of view of the order of many degrees, for this reason it would be a convenient approach for the construction of space X-ray monitors. In this paper, we compare previously reported measurements of prototype lobster eye X-ray optics called P-25 with computer simulations and discuss differences between the theoretical end experimentally obtained results. Usability of this prototype lobster eye and manufacturing technology for the nano-satellite mission is assessed. The specific scientific goals are proposed.
