Type of Research Project
- Clinical Project with Laboratory work
What is the background of the project?
Three-dimensional (3D) printers are rapid prototyping machines designed to create innovative products in the shortest possible time, unlike conventional machines. The application of 3D printers in healthcare has been increasing with numerous benefits, such as product customization, increased accuracy and development effectiveness of these products and a greater possibility of innovation. The new applicability of 3D printing brings fiction closer to reality, facilitating the development of objects from virtual modeling, reaching many areas of the market, including medicine. Medical 3D printing can be applied to the manufacture and customization of prosthetics, implants, anatomical models and an even closer perspective of biological tissue and organ. 3D printers are creating the possibility to produce anatomical models under any health conditions and custom devices for patients with specific anomalies, while assigning precision even to complex goals. Several medical institutions have manufactured and used 3D printed surgical instruments, such as intra-operative guides and scalpels.
What is the aim of the project?
Develop medical products with the help of 3D modeling, develop devices or promote adaptations in the area of surgery and urgency/emergency with the help of 3D modeling, and develop teaching simulators in the area of surgery and urgency/emergency. Promote the creation of patents on developed products.
What techniques and methods are used?
Three-dimensional (3D) modeling will be performed using Solid Works® software. Once the model is defined it will be printed on the Makerbot Replicator® 3D printer in 1.7m Lactic Polyacid. The following material resources will be used on the confection of the products: 1.7m Lactic Polyacid, Makerbot Replicator® 3D printer and Solid Works® software. The project is divided in four stages: formalization of the project (06/19), 3D modeling (07/19 to 07/21), 3D printing (07/19 to 07/21) and registration of products (07/19 to 07/21); the first step has been already done. There will be two ways of working available for the students: they either might work in a project that has been already in course, bringing new ideas and proposing adaptations, or they might create their new project from the beggining, coming up with an idea for a product in the medical field. The following steps after the first one, who has already been completed, will be done in sequence, always after the student completes the previous one. Thus, we expect either the students have a new idea for a product in the medical field, so they might create its model and, after approval by the tutor, print it, or the students might work in order to improve a project that has already been going on. If the student choose to work on a new project, in the second stage they will design their templates for a new product that might be useful in any medical area, for example, products as tracheostomy simulator, where a head and neck mannequin was created by the 3D printer, so that the procedure could be performed by undergraduated students. As soon as the idea for a product is validated by the tutor, the student will start printing it by the 3D printer. We expect the students to work a maximum of 2 weeks in the second stage, so they will have enough time to print their product and test it after already printed. Once the product is done, the student will register it in their name, gaining the patent of the product. There is no exceptions about the products that are capable of being produced, as soon as it might have a future use for any medical field. The expect results are the creation of new products that will be able to innovate the medical practice by training new medical students and facilitating the accomplishment of diagnostic and surgical procedures in the medical field.
What is the role of the student?
- The student will observe the practical experiments but will be highly involved in the analysis of the results
- The tasks of the student will be performed on his/her own
- The tasks will be done under supervision
What are the tasks expected to be accomplished by the student?
The student should be able to create their own product using the 3D printer at the end of the exchange or only work in a product that has already been in progress. Therefore, if the student chooses to start a new project, they are expected to create their prototype of the product they want to create, present to the tutor its relevance on the medical field and improve it by fixing details when advised, and thus produce it using the 3D printer. The student will have the entire month of the internship to develop the product and produce it on the 3D printer. They should be aware concerning the time they will be given to accomplish their tasks, since the whole project, from initial design to final production, should be performed during the exchange period.
Will there be any theoretical teaching provided (preliminary readings, lectures, courses, seminars etc)
Yes, the head of the department will give classes about how to work with the 3D printer and how to produce scientific articles. Also, there will always be an engineer in the department to help the students.
What is expected from the student at the end of the research exchange? What will be the general outcome of the student?
- The student will prepare a poster - The student will prepare a scientific report - The student’s name will be mentioned in a future publication
What skills are required of the student? Is there any special knowledge or a certain level of studies needed?
Practical experience in the medical field, for the product creation ideas is better and more realistic when the students understand more about medical practice. The students do not need any technical skills in working with specific application. As long as they have an idea for any products that might be worth working on, they will get all the support they need to produce it. We just expect the students to have at least an idea of product in advance, that is, before coming for the internship. If the students have no concrete idea, they might also develop their thoughts once they arrive with the help of the professor in charge. The student is expected to be past the clinical years of their graduation course or at least be doing it during the period they choose for their exchange.
Are there any legal limitations in the student’s involvement
We might accept 2 months of internship if the student has a big product to develop, but it has to be told in advance and sent with the application form.
