Texto completoThis thesis concerns the study and the development of a novel endoscopic 3D printing process based on photo-polymerization. The idea behind endoscopic 3D printing is to print 3D objects or to repair damaged parts in a dense mechanical assembly without disassembling it. The thesis aims, once the state of the art is studied, to propose solutions adapted to the endoscopic problem, then to model, design, realize and experimentally validate the two main subsystems (UV photo-polymerization through an image guide, resin spraying through a tubular pipe) which, once synchronized, provide the additive printing. Inspired by the vat polymerization method, the liquid resin is transmitted endoscopically and sprayed onto the printing surface (spraying system). Then, a UV pattern, structured by a DMD (Digital Micromirror Device), is transmitted through the image guide and focused onto the printing surface to polymerize a layer of liquid resin. These two steps are repeated several times in order to print layers on top of each other to obtain a 3D part. An endoscopic actuation system (non-integrated translation actuator) allows maintaining the probe at a distance from the printing surface equal to the focal length of the objective of the instrument. In this thesis, the endoscopic UV projection system was designed, modeled, implemented and tested. The design and performances of the optical system were presented in two international conferences. Multilayer objects were fabricated with a layer thickness of 50 μm on a circular printing area of 9.54 mm in diameter. An optical analysis method based on the use of the modulation transfer functions (MTF) was used to test the performance of the endoscopic optical system and to characterize the lateral resolution of the printed parts. Using the MTF method experimentally, a drop in optical resolution due to the image guide was estimated as high as 16 μm compared to the value obtained in the experimental setup containing the same optical components except for the image guide. The lateral resolution of the printed parts was finally limited by the resin (50 μm) and not by the resolution of the optical system. An endoscopic atomization system was also studied, implemented and tested. An endoscopic spraying system was implemented to allow a remote deposition of the resin onto the printing surface. The choice of an air atomization method was adopted. The design, control and realization of the atomization system are presented. Finally, the spraying system was combined with the UV pattern projection system. Preliminary results of printing objects were obtained and 3D parts with a thickness of 0.65 mm are printed (nine layers). Due to a phenomenon called "overspray" (during the spraying process, the resin reaches the printing area and is pushed to the sides by the air pressure that sprays it), the thickness of the layers is not constant between them, but gradually decreases, so the adjustment of the spraying parameters becomes critical. The spraying system still needs to be optimized in order to eliminate overspray and to be able to print uniform layers with a specific thickness. In addition, we have been working on a 2D visualization system but the lack of light on the printing surface prevents us from being able to visualize and control the system. In the future, we propose to spray a resin mixed with a fluorescent dye to make it possible to distinguish the polymerized zones from the uncured zones in each layer of the part
