Abstract : There are many types of 3D printers that paste mostly PLA which is a type of plastic. We have started our project as a team and changed several parts of a simple printer to be able to paste chocolate instead of plastic that called as 3D chocolate printer. We have some trouble tempering chocolate. The main problem is that the chocolate products do not have a good surface finish. We want our system to have continuous feeding, therefore we need to develop a system consists of a tank and a tempering system. To conclude, the main problem is shape of products and our purpose is to develop extruding chocolate in a desired shape. Three different experiments are done on the selected concept. Sub- systems designs are shown and told. To show every detail of the project, analysis of fluid dynamics, heat transfer and air discharge account between the syringe and chocolate tank are done and numerical values of them are obtained by calculations. In addition, seal and check- valve are selected according to its variables.

Abstract : In the project, a robot design was made for automatic storage and retrieval system and prototype production was made and tested depending on this design. The robot designed in the project was produced to carry or receive files on the shelves in the archive room. Thanks to the designed robot, the robot reaches the desired location and ensures that the file is taken from the desired location. When designing the robot, it was designed to be the first gripper to carry files. The designed gripper was put inside the box. The designed gripper works thanks to the actuator. The linear compact module is used for grip and box movement. Thanks to the linear compact module, the movement of the box with the holder is achieved by sliding up or down on the rail. The base plate has a gear motor so the system works. The bearing is mounted on the base plate and built on the turntable design. Thanks to the turntable, the linear compact module and the holder rotate. Thanks to the turntable, the robot can reach the shelves on the left or right of the corridor. In the system whose design is finished, there is a corridor between the racks and the robot can also pass through the corridor between the two racks. Depending on the design, the system was simulated. Depending on the system in the simulation, the parts on the robot were optimally produced from the 3D printer and the test of the product was completed.

Abstract : Within the scope of the project, health problems in the knee region of the human body are addressed. In this direction, a support system has been designed, manufactured, and tested is planned against knee strain. The condition that knees are exposed to most in daily life is walking. The angle formed in the knee joint during walking is approximately 0-65 °, 0-85 ° when climbing stairs and 90° when sitting. These angle values take different values in accordance with different movements. According to these values, the amount of load caused by body weight in this region varies. The knee brace is produced in a way that meets this working range. Knee brace is basically composed of three parts. These can be divided into elastic main body, plastic handles and fixing strap. The elastic front body, which is generally thought to be produced with 3d printer technology, is the most important part of the system. It helps the muscle and bone structure in the area by supporting the load that occurs during knee movements in the elasticity. Plastic parts and strap help fix the knee pad by bringing it in proper position. In this way, besides supporting the load, it helps to accelerate patella stabilization and blood flow in the region. In line with the above-mentioned purposes, the components were produced separately, and test planning was made.

Abstract : We need heat transfer enhancement to make heat transfer equipment compact, to achieve a high heat transfer rate using minimium pumping power ,for minimizing the cost of energy and material.In order to increase the efficiency of heat exchangers, the most effective method of energy saving is to increase the heat transfer coefficients on the hot and cold fluids side according to the current situation. This can be accomplished by one or more active or passive methods. The method of improving heat transfer without additional energy is called passive method. Coiled tubes, vortex manufacturers placed at the inlet, bent band pieces, screw type rotating pieces, winding wires, guiding wings, flow rotating propellers are examples of passive methods. In this project Heat transfer rates and corresponding Nusselt number distributions are studied both experimentally and numerically using different vortex promoter geometries (square and hexagonal) in different locations to illustrate the effect of vortex promoter on fluid flow.
