“…Within the methodology of design of the FDM device design, it is necessary to determine and define its required parameters and purpose. Since the work aims to design the In the research presented in the publication "Development of a three-nozzle extrusion system for conformal multi-resolution 3D printing with a robotic manipulator" [19], we can see the application of this technology to the robotic arm. To achieve ideal conditions for non-planar printing, a separate reversible print head has been designed.…”

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.

Fused deposition or fused layer additive manufacturing is a technique in which a part is fabricated layer by layer using filament or pellets-form input material. The extruder is the central part of the fused deposition additive manufacturing (FDAM) system. The extrusion mechanism is unique to the geometry and form of the feedstock material. Extrusion of filament-form material through the nozzle needs to design of a material feeding mechanism based on various filament extrusion parameters. At the same time if the material is in the form of pellets, then the design of the feeding mechanism is very different due to the shape and size of the pellets. These two different design strategies for material extrusion namely the design of the feeding mechanism of filament and pellets form materials have been a major concern to avoid unwanted deformation of extruded materials in FDAM. These two design strategies for filament and pellet-form materials have led to the development of several material extrusion strategies. The present paper reviews various material extrusion strategies developed for FDAM of filament or pellets form input material. This article presents the review of design, development, performance evaluation, and process planning for each extrusion strategy. Based on the literature review authors have suggested a possible extrusion method that can accept both forms of materials to fulfill the need for the filament as well as pellets-based additive manufacturing.

According to the CDC, 13.7% of adults in the United States have mobility issues, which is about 42 million peoplewho have that issue. The purpose of this paper is to utilize artificial intelligence and robotics packaged in a3Dprinted Circle of Command to help make the lives of those 42 million people easier [5]. A raspberry pi is usedtopower and process the voice control commands and turn the voice commands into actions that respond tothecommands [6]. The voice control is achieved through three microphones that are embedded from the inside of theCircle of Command using holes to listen to any potential voice commands, and as the raspberry pi can't input analog output which is outputted from the microphones, the microphones and the raspberry pi are connected toananalog to digital converter that allows the raspberry pi and the microphones to exchange information smoothlyRobotics is used in the stepper motor and the gear that is used to turn the top of the lazy susan, which is 3Dprintedso that there are gears on the inside of the top. There is also a home switch that will home the lazy susan. Thereisno practical application of this AI Robotic Circle of Command as it is just a prototype, and so there are no results, but it is hoped that it will be able to change some of the 42 million lives once the production of the production model begins, the production model will be larger than the prototype as the prototype serves as only a proof of concept andshows that this idea is actually doable [7].
