Innovations in the industry have also proved to be quite impressive in the medical field, where another approach is needed due to the need for personalization. Due to femoral fractures, it is not just enough to stabilize the bone, but also to have the integration of the implant with the host bone. Thisresearch is intended to undertake studies on the redesign of the distal femoral plate. The redesign had been elaborated to increase the number of people who are compatible with this type of femoral plate and also, to improve the physico-mechanical and biological properties toward to a commercial distal femoral plate made of type 316L stainless steel. Within SolidWorks software, a static simulation has been run after there have been defined restraints, external loads, and a mesh. The parameters were similar to those after the implantation. Taking this reason into consideration, the final results will be improved by modifying plate’s material from 316L to titanium alloy Ti6Al7Nb to increase the capability and biocompatibility. Moreover, the geometry of the distal femoral plate changes to decrease theweight and time of osteosynthesis. The final implant is parametrized 3D models that handle all day-to-day activities and has a weight 50% lower than that of the commercial implant.

“…To analyze the surface quality of the parts made by CFRP processed using AWJC the surface parameters are measured in three zones: initial damage zone, smooth cutting zone and rough cutting zone (figure 1) [2,6,7]. When is analyzed the dimensional accuracy, the kerf geometry (figure 2) and the part contour is measured [2,8].…”

The main objective of the paper consists in remanufacturing of a part, through Abrasive Water Jet Cutting, using a method of reverse engineering based on 3D scanning. The characteristics of this process, the equipment and the main applications are presented. The research starts with manufacturing of a master model made by CFRP. This master model is a complex part cut by abrasive water jet cutting. In scanning process was used the 3D Scanner Artec Space Spider and the point cloud was processed using Artec Studio 11 software. By using this new 3D model was manufactured a new part, with the same setup. The quality characteristics (accuracy and surface quality) of this part was compared with the master model. The paper presents the advantages and disadvantages of this reverse engineering method applied on abrasive water jet cutting process.

Selective laser melting (SLM) is a contemporary manufacturing method that offers numerous advantages for producing various components. This research focuses on the examination of a dental implant sample fabricated using the SLM method. The investigation encompasses multiple aspects, including hardness, dimensional accuracy, strength, and surface properties. The results demonstrate that the hardness of the SLM sample is comparable to that of machined samples, establishing it as a viable alternative to traditional production methods. Dimensional tests reveal that the SLM sample adheres to the required acceptance limits for critical dimensions. The strength of the sample, with a value of 700 MPa, proves to be acceptable for medical applications. The presence of surface porosity and holes in the SLM sample highlights its potential for enhanced bone ossification. However, challenges associated with thread construction in the SLM process require further attention. Overall, this research showcases the promising aspects of the SLM method for dental implant production, while also identifying areas for future investigation and improvement.This article is protected by copyright.
