Abstarct: The primary objective in fixture design is to increase production while considering the required quality and reducing manufacturing costs. A machining fixture consists of various components, including fixture body plates, locators, clamps, and supports. These components are typically assembled using assembly methods, often involving screws and bolts, which can be time-consuming, costly, and require high precision. Therefore, this thesis explores the feasibility of utilizing additive manufacturing technology in the fabrication of a fixture for non-heavy drilling operations. To achieve this goal, a fixture for machining aluminum parts were selected. Various parameters were studied in the first phase to assess their impact on the quality of the final product. These parameters included laxyer thickness, part density, feed rate, nozzle diameter, overlap, and material. Design of experiment were conducted using the full factorial method to study the effects of input parameters on the outputs. Three levels were chosen for each parameter: laxyer thickness (100, 150, and 200 microns) and part infilling factor (80%, 90%, and 100%), and these were entered into the design of experiments table. Output parameters included maximum deformation, fixture positioning accuracy, hole taper over its length, and final cost. To measure the maximum deformation of the workpiece, several aluminum workpiece drilling tests were performed. The effects of feed rate, hole diameter, and hole position were investigated on the workpiece's maximum deformation during the experiments. Through the experiments on all the fixtures, the maximum maximum deformation was observed in the fixture with 100% infill factor and a 100-micron laxyer thickness. This result aligns with the findings of other researchers in this field and can be justified baxsed on their research. Deviating from the best case of laxyer thickness ( 100 microns), in choosing between 150 and 200 micron laxyers, the 200 micron option will be the right choice. Because by maintaining the maximum deformation, the cost of printing the model will be much lower. The second visible point in these experiments is the lack of noticeable effect of infill factor on the maximum deformation in the thickness of the upper laxyers (200 microns). This issue also shows that the effect of reducing the number of connections between laxyers in the thickness of the upper laxyers has a much greater effect than increasing the infill factor on the bending strength. Two other significant points in these experiments are for the thickness of the laxyers of 100 and 200 microns. In the laxyer thickness of 100 microns, increasing the infill factor from 80 to 90% did not have much effect on the maximum deformation (at both the advance speed of 31.5 and 63 mm/min). This is while increasing the infill factor to 100% has greatly increased the maximum deformation of the model.
