“…Whether it is the use of printheads installed on robotic arms, or oversized printing used, for example, in construction, the creation of tissue through the layering of biological material, or new materials in this area, the devices used in these areas have one thing in common. They all work on the same principle of layering thermoplastic or other materials in planar layers [21]. This is based on theoretical assumptions, which form a partial solution related to the design of an atypical structure for FDM technology.…”

This article presents the variability of Fused deposition modelling (FDM) technology and the possibilities of its use in the design and implementation of a prototype atypical device. The assumptions of the behaviour of individual components and subsystems of the design result from an extensive application of the finite element method and motion analysis of subsystems and various parts of the structure. The use of this method to such an extent accelerated the design process and its implementation. The proposal itself reflects the current state of this technology and its focus is on improving sustainable development. As is generally known, great efforts are currently being made to reduce plastic waste volume and its environmental burden. The proposed concept is modified to replace the final treatment of the top layers of the models, called “ironing” by non-planar layering of material. At the same time, it points out the advantages of this method in reducing energy requirements and the time required to produce models. The conclusion is a conceptual design of a printhead for a proposed prototype, designed to use recycled FDM, intending to streamline the possibility of recycling with little serial and piece production. This process thus closes the circle of opportunities published by us, which in the future can contribute to the optimisation of this technology towards increasing the efficiency of resource use, reduction of energy demands and environmental burden.

“…In this system, the layer-slicing algorithm and tool-path planning were used to eliminate the need for generating the support structure for thin shell parts. Some other research in the literature has focused on the support structure removal generated due to bridging and overhang features in the printed parts [142]. By using these methods, the time and material required for the printing process will be discounted accordingly.…”

The unique design freedom offered by additive manufacturing (AM) technologies enables engineers to develop more innovative products with relatively lower costs within a shorter period of processing time in comparison with conventional manufacturing methods. On the other hand, the unique capabilities of AM have created a platform for researchers to combine several engineering methods with the new manufacturing technique to grow industrial applications as well as resolve the existing issues with AM processes. Understanding the research values that AM offers academic environments, this paper performs a systematic survey on AM-related research topics in the fields of mechanical engineering and materials science that have attracted much attention from research teams over the last few years. These topics, namely process modelling in AM, innovative research in AM, generative design by AM, material characterisation in AM processes, and finally, design for additive manufacturing (DfAM), are notably investigated through this study.

“…This includes expertise in trajectory planning for robotic arms, optimal material extrusion, and balancing speed, precision, and material qualities. The paper [3] plays a crucial role in this context, providing a novel perspective on controlling fibre orientation with a robotic manipulator and a multi-nozzle extrusion system. This approach significantly impacts the produced items' mechanical properties and surface finish, directly aligning with our focus on enhancing the quality and precision of 3D-printed components.…”

The manufacturing sector is increasingly integrating additive manufacturing and robotics, marking a significant evolution in production methods. This paper delves into the field of robotic-assisted additive manufacturing, highlighting the use of robotic arms to enhance the efficiency and precision of the 3D printing process. Central to this research is the adaptation of the Universal Robot UR3e model within a 3D printing system. The study confronts and resolves numerous challenges, such as selecting a suitable printing extruder, determining appropriate material types, and optimizing nozzle dimensions. Essential aspects like developing control software for the robot arm and extruder, interpreting 3D models into robotic instructions, and calibrating the hardware are examined in detail. These processes involve fine-tuning the arm's motion, optimizing material extrusion rates, and conducting comprehensive testing to ensure accuracy and quality of the printed objects. This multidisciplinary approach underlines the complexities of merging 3D printing with robotic technology, necessitating expertise across mechanical, electrical, automation, and software engineering domains. A key focus of this paper is not just the technical implementation but also the practical outcomes. Experiments were conducted to evaluate the compatibility between the G-code program and the RoboDK software, leading to the successful physical realization of the printed products. These experiments demonstrated not only the feasibility of the system but also its potential for producing high-quality, precise 3D printed objects. The results obtained underscore the effectiveness of the integrated system in actual manufacturing scenarios, paving the way for advanced applications in robotic-assisted 3D printing.
