The continuously decreasing life cycle of modern products leads to new challenges for product development. Additive manufacturing (AM) processes are able to support faster development by rapid production of samples and prototypes. However, the material properties of components produced by common (plastic-) 3D-printers are often insufficient for functional prototyping. A well-established way to improve the properties of plastics is the embedding of reinforcing fibers. Thus, this paper shows a method for fiber-reinforced 3D-printing. Through this combination, several restrictions of conventional composite production can be eased and additional freedoms of design are gained. To support the design of such parts, an adapted design methodology for fiber-reinforced 3D-printing is developed.

Purpose With the overarching idea of disruptive technology and its effects on business, this paper focuses on how companies strategically consider meeting the challenge of a disruptive technology such as additive manufacturing. The purpose of this paper is to describe and discuss changes in positions and roles related to the implementation of a disruptive technology. Design/methodology/approach Additive manufacturing could be expected to have different consequences for parties based on their current supply chain positions. The paper therefore investigates companies’ strategies related to various supply chain positions and does so by departing from a position and role point of view. Three business cases related to metal 3D printing - illustrating sub-suppliers, manufacturers and logistics firms - describe as many strategies. Data for the cases were collected through meetings, interviews, seminars and secondary data focusing on both current business activities related to additive manufacturing and scenarios for the future. Findings The companies attempted to defend their current positions, leading to new roles for them. This disconnects the change of roles from that of positions. The changed roles indicate that all parties, regardless of supply chain positions, would move into competing producing roles, thereby indicating how a disruptive technology may disrupt network structures based on companies’ attempts to defend their positions. Originality/value The paper contributes to previous research by reporting a disconnect between positions and roles among firms when disruption takes place. The paper further denotes how the investigated firms largely disregarded network consequences at the disruptive stage, caused by the introduction of additive manufacturing. The paper also contributes to research on additive manufacturing by including a business dimension and linking this to positions and roles.

Additive manufacturing can be considered an innovative and high-technology and one of its characteristics is that it has limited dependency on the location. The purpose of this study is to examine this aspect by investigation how additive manufacturing is spreading globally. The focus is on established manufacturers of industrial additive manufacturing machines. It was found that the early-stage diffusion of this technology is primarily in advanced economies. Furthermore, many of the currently established companies that manufacture industrial 3D printers come from already existing companies that expanded into AM or that led to spin-off companies. The complexity of AM which requires expert knowledge across a range of fields may be the key reason for this finding. Recommendations for further research are provided.

Fourth Industrial Revolution gave birth to few different technologies, not known until now. One of them is 3D printing. If subtracting manufacturing is part of Industrial Revolution 3, Additive manufacturing is for sure part of Industrial Revolution 4.0. 3D printing has the potential to transform science and technology by creating bespoke, low-cost appliances that previously required dedicated facilities to make. 3D printers are used to initiate chemical reactions by printing the reagents directly into a 3D reactionware matrix, and so put reactionware design, construction and operation under digital control. Some models of 3D Printers can print uniquely shaped sugar confections in flavors such as chocolate, vanilla, mint, cherry, sour apple and watermelon. They can also print custom cake toppers–presumably in the likeness of the guest of honor.

Additive manufacturing (AM) is the most advanced recently trending manufacturing technique that employs 3D printers to create 3D objects by layer upon layer fabrication from the base to the top. The required trajectory of the fabricating tool to create the layer can be well programmed by CAD software available in the market. The 3D CAD model in the computer can be manipulated and customized for different design needs of the product. These manipulations in model and quick fabrication process make the system a flexible and an effective one. This chapter discusses the AM application in educational system by describing the individual AM processes, their limitations, advantages, feasibility in general conditions, and planning for future generations to get accustomed to this technology from the early education in schools to the specialized education in universities. The technology enables students to convert 2D objects into 3D on the CAD software and feel them physically by 3D printing. AM also enables teachers to demonstrate their ideas easily to students.

AbstractThe present paper shows an innovative multirotor Unmanned Aerial Vehicle (UAV) which is able to easily and quickly change its configuration. In order to satisfy this feature, the principal structure is made of an universal plate, combined with a circular ring, to create a rail guide able to host the arms, in a variable number from 3 to 8, and the legs. The arms are adjustable and contain all the avionic and motor drivers to connect the main structure with each electric motor. The unique arm design, defined as all-in-one, allows classical single rotor configurations, double rotor configurations and amphibious configurations including inflatable elements positioned at the bottom of the arms. The proposed multi-rotor system is inexpensive because of the few universal pieces needed to compose the platform which allows the creation of a kit. This modular kit allows to have a modular drone with different configurations. Such configurations are distinguished among them for the number of arms, number of legs, number of rotors and motors, and landing capability. Another innovation feature is the introduction of the 3D printing technology to produce all the structural elements. In this manner, all the pieces are designed to be produced via the Fused Deposition Modelling (FDM) technology using desktop 3D printers. Therefore, an universal, dynamic and economic multi-rotor UAV has been developed.

Traditional Manufacturing

In terms of the development of 3D printers we can say that in the first stage of evolution the huge majority of them were able to print 3D using 3 axis numerically controlled. Currently there are several types of printers that can print in 4 and 5-axis developed using classical solutions (portal or parallel structure). Another direction of development is the combination of 3D printers and traditional manufacturing equipment, with an already existing commercial solution (Hermle MPA 40) that combines milling and MPA technology (Metal Powder-Application). This paper presents a hybrid equipment that can be placed in the specific additive manufacturing category, combining milling operations (4 axis) and turning with 3D printing using FDM technology. The machine uses stepper motors for driving kinematic axes, a DC motor (16 000 rev / min) to drive the main shaft of the mill and a three-phase motor for turning. The software used for milling and turning is Mach3, while MatterControl is used for 3D printing.
