“…The generation on the principle of 3D printed by FDM structure is one composed of three layers lower minimum and the same upper and three-layer perimeter so as you can see in figure 2. To generate the inner part is a type structure with 40% density minimum in order to have a durable structure, but also with good properties of requests but also generate involute gear profile on submission of material [6]. At the basis of this study, it possible to seen that the made wheel profile on FDM is less precise in rapport with generating with CAD.…”

The aim of the work is conduct to highlight how the technological parameters has influence of 3D printed DLP on the generation of wheel, made from resin type material. In the first part of the paper is presents how to generate in terms of dimensional aspects specific design cylindrical gears, conical and worm gear. Generating elements intended to reduce the cost of manufacturing of these elements. Also are achieve the specific components of this work are put to test with a laboratory test stand which is presented in the paper in the third part of the paper. The tested gears generated by 3D-printed technique made with 3D printed with FDM or DLP technique. After the constructive aspects, proceed to the identification of conserved quantities, which have an impact both in terms of mechanical strength, but his cinematic, in order to achieve a product with kinematic features and good functional domain specific had in mind. The next part is carried out an analysis of the layers are generated using the DLP and FDM method using an optical microscope with magnification up to 500 times, specially adapted in order to achieve both visualization and measurement of specific elements. In the end part, it will highlight the main issues and the specific recommendations made to obtain such constructive mechanical elements.

Nowadays, the increasing use of plastic materials in friction and wear applications, particularly in industrial robotic grippers, is a growing trend in modern industry. Plastics are replacing traditional materials like metals and composites due to their unique properties and significant advantages. Plastic materials used in industrial robotic grippers offer several advantages, such as their low friction coefficient, enabling smooth and precise movement of the gripper and minimizing the risk of damaging the objects being manipulated. This paper presents a comparative study and analysis of the friction coefficient between various plastic materials and the C45 alloy steel, a superior alloy used in industrial applications. The investigated materials include PETG, PLA, PLA with aluminum, ABS, two types of TPU, and two types of UV-sensitive resins. This study aims to evaluate the friction performance of these materials in order to identify the most suitable options for friction and wear applications, such as industrial robotic grippers. To achieve this, dry kinetic friction tests were conducted between 3D printed plastic material samples manufactured by using FDM and SLA technologies, and the C45 alloy steel on the CETR UMT-2 tribometer. The friction coefficient was measured by recording the force required for displacement in two horizontal directions.

“…One of these limitations is the low strength of the plastics used in FDM compared to the materials used in fasteners. Another limitation is the surface roughness caused by the layer thickness of the FDM [24][25][26]. This feature leads to both reduced strength and tolerance problems as screw diameters are reduced.…”

This study aims to investigate common fastener implementation methods for parts manufactured with Fused Deposition Modeling (FDM). Although fastener applications for FDM manufactured parts are already in use, the effects of these methods on tensile and bending forces have not been examined. Test samples with different design techniques and infill ratios were produced using Polylactic Acid (PLA), and tensile strength and flexural and tightening torque tests were performed. Four of the of the most preferred fastener applications were studied. Two of the applications use a heat-set insert, and the other two applications use square nuts. Test samples were designed for the applications and printed with three different infill ratios. The production times and material consumption for these different applications were explained and evaluated. Different drawbacks and advantages were investigated for different applications. It has been observed that the strength of the basic heat-set inserts depends on the surface adhesion and is less affected by the filling rate. Advanced heat-set inserts adhere better to the surface, so the infill ratio is the determining factor in strength. The embedded nut methods depend on the infill ratio up to a certain load. As the load increases, the influence of wall thickness becomes increasingly evident. These findings not only contribute to enhancing structural integrity but also offer invaluable insights into optimizing connection methods for diverse applications.
