Standard Arrangement

This work presents the results of work on a 3D printing device with a non-standard arrangement of the table and nozzle, which is necessary for the additive production of plastic cases for electronic devices. The non-standard arrangement of the table is caused by the need to use special accessories to hold third-party embedded elements of the case. A metal part - a contactor - is used as an embedded element. Due to the specific mortgage they made, as well as the experimental equipment, the authors came to the conclusion that it is economically more expedient to design and manufacture a prototype 3D printer than to modify the existing device. A sample of the FDM printing device was designed, manufactured and tested.

Complex Approach

In accordance with a concept of additive technologies there occurs a necessity of applying new approaches to designing parts. One of the main tools to be operated is a numerical simulation, capable of providing a designer with the complex approach to the development of new articles in case of finesse. A preliminary simulation model of structurally-gradient materials in the software package ANSYS has been created in this work for predicting mechanical characteristics of compact samples of materials and structures. It provides the results of tensile calculations of stress strain behavior of samples obtained by finite-element simulation, as well as gives comparison thereof with the test data obtained after manufacturing using a method of selective laser melting.

The Impact

PurposeThere are many academic contributions dealing with the impact of additive manufacturing on supply chains (Ben-Ner and Siemsen, 2017; Durach, 2017; Gravier and Roethlein, 2018; Brown, 2018; Rogers et al., 2016; Sasson and Johnson, 2016; Nyman and Sarlin, 2014). But how future supply chain design may differ from today is still vague. In this article, possible scenarios are discussed and decision support is provided for the management, which is responsible for long-term strategic decisions.Design/methodology/approachThis papers introduces the general characteristics of additive manufacturing and its next steps of development. Based on these technological assumptions various scenarios are systematically derived applying the standardized nomenclature of SCOR-model. Resulting threats and chances will be discussed and finally brought to a conclusion.FindingsWith the spread of additive manufacturing, the industry has the opportunity to pursue completely new approaches in terms of product development, design and product properties. This not only leads to new competitive models and the possibility of customer individualization of the products down to volume “1”. In addition, there are new models for supply chain management that can be used to react quickly and flexibly to customer requests. Already today new approaches for the cooperation between partners play an essential role.For start-ups, market entry should be simplified by using the resulting opportunities.Research limitations/implicationsFuture developments and especially the development speed of additive manufacturing are not predictable. Therefore, the expected scenarios may differ from reality and lead to a different supply chain design. There will also be industries that can use additive manufacturing much more intensively than others – not least because of the technological restrictions of the manufacturing process. Corporate culture and the overcoming of technical challenges are a decisive factor.Practical implicationsThis paper gives supply chain management an outlook on future development opportunities. This enables management to set the right course for a future-oriented position today.Social implicationsThe changes in the supply chain will open up new business models while existing models will disappear. This leads to a change in the field of logistics but also for many technology providers. As a consequence, there will be serious changes (opportunities and risks) for the employees involved and their working environment.Originality/valueThis paper enables management to understand the scope and impact of upcoming changes. In this way, it significantly promotes awareness-raising and contributes to the future-oriented proceeding of companies.

The aim of the additive manufacturing (AM) is a production of physical objects by adding material layer-by-layer based on virtual geometry developed in the computer system. The main criteria for the division of additive manufacturing methods are the way to apply the layer and the type of construction material. In most projects, the choice of method is a compromise between costs and properties (e.g. physical, chemical or mechanical) of the manufactured object. Currently, AM methods have found application in many areas of life, including industrial design, automotive, aerospace, architecture, jewellery, medicine and veterinary medicine, bringing many innovative and revolutionary solutions. The purpose of this article is to review of the additive production methods and present the potential of medical application.

Now, an increase in productivity due to computer-aided manufacturing using digital prototypes is reflected in the formation and development of additive manufacturing technologies, also known as «Layer Synthesis». The use of additive technologies allows us to provide individualization of production, reduce material-intensive costs, increase the economic efficiency and effectiveness of the production of body elements of electronic equipment (REA), as well as improve the quality of the body elements produced. In additive manufacturing, it is necessary to consider many parameters and characteristics incorporated in the installation. To ensure the quality of additive production, it is very important to observe the required temperature conditions depending on the material used. The article deals with the issues of setting the temperature regimes and controlling the additive system. A comprehensive indicator of product quality is proposed, taking into account the safety parameters and identification indicators of the properties of polymers used in additive manufacturing.

Abstract In challenging the assumption of autistic social uninterest, Jaswal & Akhtar have opened the door to scrutinizing similar unexamined assumptions embedded in other literatures, such as those on children's typically developing behaviors regarding others’ minds and morals. Extending skeptical analysis to other areas may reveal new approaches for evaluating competing claims regarding social interest in autistic individuals.
