When studies in the literature are examined, there are studies in which various methods are applied to students' stoma care knowledge and skills. Additionally, it is seen that there are studies using moulage or 3D printers as simulation applications in nursing education. However, there is no study on high-reality simulation application using 3D printer and moulage technique together.nIn this research, the effect of the stoma created with a 3D printer in a high-reality simulation on the stoma care knowledge and skills, satisfaction and self-confidence of nursing students will be examined by using the moulage technique. In addition, this application will be compared with nursing students' stoma care practices in the stoma model, which is classified as low-reality simulation. We think that our project will be unique in this field, as it uses current technological methods together in this planned research and is different from similar studies.

A stoma is an opening created by inserting an organ into the skin using a surgical method. Colostomy, ileostomy and urostomy, in which excretion is provided through an opening created on the anterior wall of the abdomen outside normal anatomical pathways, are among the most commonly created stomas. Although stomas are created for various reasons, they are most commonly opened due to colorectal and bladder cancers.

According to the International Agency for Research on Cancer (IARC), colorectal cancer ranks 3rd and bladder cancer ranks 10th in all ages and genders. Although the exact number of individuals with a stoma worldwide is unknown, it is estimated that 18-35% of individuals diagnosed with cancer have to live with a stoma temporarily or permanently during the treatment process. In this regard, it is thought that the number of individuals with stoma will increase with the increase in colorectal and bladder cancers. This increase also increases the need for nursing care of individuals with stoma. Accordingly, it is important to provide this care skill to nursing students, who are the nurses of the future, during nursing education.

Nursing education; It includes multifaceted education and training activities including theoretical, laboratory and application areas. It is thought that students who gain sufficient knowledge and experience about stoma care during their studies provide effective care to individuals with stomas when they start working as professional nurses, and that their adaptation to stoma and quality of life increases with this care. Stoma care is among the basic nursing skills that nurses apply autonomously. While training student nurses on stoma care, methods that improve their cognitive, sensory and psychomotor skills should be used. In this context, with technological developments, various methods such as computer systems and simulation applications are becoming widespread in nursing education day by day.
