“…It is known as additive manufacturing, which builds physical objects by applying successive layers of material of a specified thickness using a printer-understandable code generated by a so-called Slicer [ 11 , 12 , 13 ]. Compared to traditional component manufacturing methods, the ability to 3D print widens the possibilities for design, modification of a designed component, and visualization [ 14 ]. Rapid prototyping is supported by reverse engineering and has applications in the field of medical science.…”

This paper presents the metrological quality and mechanical properties of models in the form of hook holders manufactured from MED610 polymer material using PolyJet Matrix (PJM) technology. Measurements in the dimensional and shape analysis were made using the optical method with a microscope. The mechanical test was estimated by static tensile testing of the fabricated parts. A comprehensive approach to both the analysis of test results based on standardized samples and real hook models makes the presented results of great scientific and engineering value and creates the possibility of practical use in the medical industry, which has not been so comprehensively presented in the currently published research papers. Analyzing the results of measurements of the geometrical characteristics of the elements, it can be concluded that the PolyJet Matrix 3D printing technology has demonstrated a high level of precision in manufacturing the prototype parts. The static tensile test of samples, taking into account the printing directions, showed a high anisotropy of mechanical properties. The results of both strength and simulation tests indicate that it is necessary to assume a relatively high safety factor, the value of which depends on the direction of printing, which, in the case of such a responsible medical application, is very important.

“…However, with current trends in dry machining, aluminium alloys tend to adhere to the cutting tool, which results in tool wear [2]. The wear mechanisms can affect hole quality by producing rough surfaces, additional burrs around the edges, roundness deviation, cylindricity, and high cutting forces [3][4][5]. According to Nouari et al [6], carbide tools have been proven to perform better for the dry machining of aluminium alloys than high-speed steel (HSS) tools.…”

Performance Analysis of Multi-Spindle Drilling of Al2024 with TiN and TiCN Coated Drills Using Experimental and Artificial Neural Networks Technique

Multi-spindle drilling simultaneously produces multiple holes to save time and increase productivity. The assessment of hole quality is important in any drilling process and is influenced by characteristics of the cutting tool, drilling parameters and machine capacity. This study investigates the drilling performance of uncoated carbide, and coated carbide (TiN and TiCN) drills when machining Al2024 aluminium alloy. Thrust force and characteristics of hole quality, such as the presence of burrs and surface roughness, were evaluated. The results show that the uncoated carbide drills performed better than the TiN and TiCN coated tools at low spindle speeds, while TiCN coated drills produced better hole quality at higher spindle speeds. The TiN coated drills gave the highest thrust force and poorest hole quality when compared with the uncoated carbide and TiCN coated carbide drills. Additionally, a multi-layer perceptron neural network model was developed, which could be useful for industries and manufacturing engineers for predicting the surface roughness in multi-hole simultaneous drilling processes.

“…Designing, fabricating, and then measuring a textured surface with a specific quality and distribution of individual morphological features means that the nominal, real, and measured surfaces are not identical. In each case, there are errors that affect the perception of such a surface [ 49 , 50 ]. There are technological limitations associated with the component fabrication process, such as layer thickness and minimum laser beam diameter, preventing the formation of small features on the surface.…”

This paper presents the results of an experimental study to evaluate the possibility of using SLM additive technology to produce structures with specific surface morphological features. Qualitative and quantitative tests were conducted on samples fabricated by 3D printing from titanium (Ti6Al4V)-powder-based material and analysed in direct relation to the possibility of their use in medicine for the construction of femoral stem and models with a specific degree of porosity predicted by process-control in the self-decision-making 3D printing machine. This paper presents the results of the study, limitations of the method, recommendations that should be used in the design of finished products, and design proposals to support the fabrication process of 3D printers. Furthermore, the study contains an evaluation of how the printing direction affects the formation of certain structures on the printed surface. The research can be used in the development of 3D printing standardization, particularly in the consideration of process control and surface control.
