Full textThis thesis covers the design of pneumatic soft robots, which move thanks to deformation using pneumatic chambers. We contribute to the design of a robot from the formulation of the need to the manufacturing of the robot. We address the problems associated with the design and manufacture of these robots. For design, we propose a genetic algorithm accelerated by the use of an AI model enabling rapid estimation of the behavior of new geometries and the search for solutions. For manufacturing, we propose an instrumented silicone additive manufacturing platform enabling the acquisition of point clouds on each produced layer. Indicators are then proposed to monitor ongoing production and the integrity of soft robots, and these indicators are evaluated experimentally

Full textMost additive manufacturing processes fabricate objects by stacking planar layers of solidified material. As a result, produced parts exhibit a so-called staircase effect,which results from sampling slanted surfaces with horizontal planes. This negatively impacts the surface finish and accuracy of a part. While thinner slices reduce this effect, it remains visible in areas where the input shape surfaces almost align with the layers. This horizontal slicing scheme also impacts the resilience of the printed part as layers cannot be aligned to obtain the maximum strength. As with layers, the orientation of trajectories within a slice is often constrained and cannot be freely controlled. In this thesis, we exploit the ability of some additive manufacturing processes to deposit material slightly out of the plane to overcome these limitations. We mainly focus on extrusion-based technologies, particularly Fused Filament Fabrication technology, since most printers in this category can deposit along slightly curved paths underdeposition slope and thickness constraints. Our algorithms are split into two categories,the ones that produce freely oriented trajectories inside a layer and the ones that curve the layers themselves. My first contribution focuses on deposition trajectories inside a layer, allowing the users to control their orientation. This led to two novel infill patterns aiming at two different objectives. The first is a sparse infill that follows a direction field and density field, while the second is a dense, oriented staggered infill pattern with minimal porosity. My second contribution focuses on printing with curved layers, exploring two different approaches. The first one operates directly on the layers, making them either followthe natural slope of the input surface or, on the contrary, intersect the surfaces at a steeper angle, thereby improving the sampling quality. We demonstrate that this approach enforces all fabrication constraints, including the guarantee of generating collision-free toolpaths. The second method builds atop the staggered infill introduced before, generating trajectories with free orientation throughout the part's volume

Full textAdditive manufacturing is a rapidly growing technical area within which a wide variety of methods have been developed. These new processes provide a higher degree of geometrical freedom when building specific objects for small series production or for custom-made use. The benefits against traditional processes are reductions of time, of cost and of material consumption, thanks notably to the suppression of specific equipment (e.g. moulds). Nowadays different types of materials are processed in additive manufacturing, like thermoplastic polymers (PLA, ABS, PA), metals or ceramics. However crosslinkable elastomeric materials like silicones have hardly been considered although they are widely used in several industries. This study focuses on 3D printing of new silicone formulations, in a view to creating new structures of light densities. Material extrusion (or fused deposition modelling, FDM) is used as an additive manufacturing process in which material is selectively dispensed through a nozzle. This method, commonly used with thermoplastic materials, requires a number of modifications and improvements with silicone formulations which containing silica nanofillers. In particular, the network, rheology and curing time have been studied to come up with a formulation that both fits perfectly with additive manufacturing and generates good mechanical properties of the finished product. Furthermore enhancement of homemade 3D printer characteristics seems to be obvious to fit also with this kind of new formulation and new design of pieces. Finally, new structured objects have been developed to reproduce the two most important parts of an orthopedic liner

Full textBy using production solutions from Additive Manufacturing (AM) technologies, the industry is opening up new possibilities for manufacturing high added value parts. In order to be fully exploitable, these manufacturing processes must allow the production of parts whose quality is adapted to the needs of the industry. This work focuses on two aiming points of quality control in AM applied to Electron Beam Melting (EBM) technology.The first point deals with the impact of a part position in the manufacturing space of a machine on the geometric quality of this part. To characterize the manufacturing space of the Arcam A1 machine, several series of parts are manufactured at different locations of the space, then compared to their initial design. The differences measured between the parts and their desired geometry show that the periphery of the manufacturing space is a zone subject to important geometrical defects. These defects are characterized and solutions are proposed to limit the impact on the geometrical quality of parts.The second point deals with the porosity of manufactured parts. When the energy supply of the electron beam is not adequate to melt the powder properly, pores can form in the material of the manufactured parts. The geometry and material of the parts make it difficult to detect its pores. A detection method is provided to detect the presence of pores in parts via a standardized control on an item that copies the parts merging conditions. This method offers two control alternatives: an optical control (fast, affordable but not very accurate) and a tomographic control (more accurate than the previous one but slower and costlier). An innovative image processing algorithm is developed as part of this study to make the item tomography scans more reliable

Full textFramatome is one of the world leaders in the nuclear industry. Its main business is the manufacture of nuclear reactors and nuclear fuels.All the reactors can be divided in two main categories: power reactors and research reactors. Nuclear research reactors are small nuclear reactors used by universities and research centers. Their purposes are training, research, development of power reactor components, production of neutrons for scientific experiments, irradiation of materials for industry and manufacture of radioisotopes for the medical field. Since nuclear research reactors are small, their fuels must be dense in uranium to sustain nuclear reactions and maximize their yield. The RERTR program (Reduced Enrichment for Research and Test Reactors), set up in 1978, pursues the objective of optimizing the fissile uranium density of research reactor fuels to offset the 93% reduction in enrichment to 20% in 235U. After having developed new alloys with higher density, other research is then put in place to allow the improvement of the cores by various means. One of the possible ways is to work on the geometry of the plate core.Current techniques for manufacturing research nuclear fuel plates are rolling and extrusion from cold-compacted metallic uranium powders. These two technologies have three main limitations. First, they require the plates to have planar or cylindrical core geometries whereas the geometry of nuclear reactions is rather spherical and dictated by neutron leakage and moderation in the reactor core. Then, these technologies are based on large deformations. The core of the uranium plate is indeed diluted in a ductile aluminum matrix to allow this deformation while remaining in the elastic domain. The percentage of aluminum added in the core is about 40% by mass. Finally, the large deformations applied during rolling or extrusion induce waves of deformation on the plate core and thus the formation of extra thicknesses on the plate core. They are compensated by the reduction in the thickness of the uranium plate core by almost 20%. All these technological constraints induce a loss of 235 uranium mass by a factor of two in the plate core. The change in technology could make it possible to overcome these limitations.The fuel plates of nuclear research reactors are objects with high added value, of small size (typically 1000 x 60 x 1.3 mm), produced in small series, not standardized, with many different designs and using metal powders. These features are perfect for additive manufacturing. In addition, the current improvements sought are geometric optimization with more complex geometries than those currently possible. These advantages are again typically those of additive manufacturing. So, we have a use case that seems well suited to additive manufacturing. However, there is a major difficulty. The uranium metal powder used is radioactive and flammable in air. It needs to be handled in a glove box, which complicates the implementation of additive manufacturing technologies.It is precisely to meet these requirements that a research project was born between the company Framatome and the University of Technology of Belfort-Montbéliard to study the additive manufacturing processes likely to manufacture nuclear fuel plates of research. Two additive manufacturing processes were selected and tested: Cold Spray and Laser Beam Melting

Full textCurrently, HTCC and LTCC (High and Low Temperature Co-fired Ceramics) parts are produced by two processes: tape casting for the dielectric ceramic part and screen printing for the realization of metal tracks and vias. The main objective of this work is to propose a new process for obtaining monolithic multi-material parts using the coupling of two additive manufacturing technologies. In this respect, a hybrid additive manufacturing process capable of building a 3D ceramic / metal part could be of major interest in the manufacture of such electronic components. Stereolithography and robocasting seem to be complementary processes to achieve this goal. The advantage of using additive manufacturing instead of conventional methods is to be able to achieve forms that can not currently be obtained in microelectronics, which would allow a performance gain compared to current circuits. A strategy combining stereolithography and robocasting is proposed for the simple manufacture of HTCC and LTCC multi-material parts. The model parts are electronic circuits in the three dimensions of the space including a dielectric substrate as well as horizontal tracks and vias. To improve the performance of current circuits new geometries are being studied, such as armored or inclined vias. They will then be characterized in microwave to verify the application of selected materials in these frequency ranges
