Abstract: Restorative surgical systems have not changed much amid the previous century because of the absence of exact minimal effort workbench for testing any new change. A significant reason hindering the development of endoscopic ultrasound (EUS) in Asia is the lack of preparing benefits capacity. We planned to assess the adequacy of a fleeting organized EUS preparing program in enhancing the learning and ability of EUS among students tentatively. In our work, we have developed a 3D stomach model, which intends to improve the gastrointestinal tract examination preparing technique for specialists before they can operate endoscopic ultrasonography for positive patients. As the animal model does not fit the standing 3D structure of a stomach, consequently purpose of this task is to make a 3D stomach model utilizing a 3D printing innovation with both exceptional mechanical properties and ultrasound visibility. 3D printing is able to produce 3D virtual shape item. 3D printing incorporates a wide assortment of assembling methods leveraging computerized formation of materials in layers to make freestyle geometries. For quite a long time, these strategies were widely utilized as a part of the field of bio assembling to deliver dummy models. It is getting better known by its precision and as the subject of discussion in articles. Selective laser sintering (SLS) producing procedure is utilized for prototyping of human stomach. Selective laser sintering (SLS) process can get to be a standout amongst the most suitable fabricating strategies in coming couple of years since it can effortlessly have created complex shapes. Utilization of this procedure turns out to be broader, with the principle points of interest being an extensive variety of assembly materials accessible. So SLS can suit different applications all through the production process. It comes ahead of schedule with three principal applications: theoretical models, useful models, and demonstration models. In any case, the scope of polymer materials that can be handled by SLS today is still exceptionally constrained, confining most SLS parts to be produced using nylon (polyamide). Furthermore, another disservice of SLS process that it is both tedious and costly when another material comes into utilization. In this report, we will the dimensional precision, mechanical properties and ultrasound visibility of the stomach models produced by this SLS process with various polymer materials.
