Abstract
3D printing is the new and preferred method for rapid prototyping parts in commercial and personal manufacturing. For flexible food safe polymer parts, the method remains to be casting them in molds. This process takes more time, effort, and money than 3D printing. This thesis investigates different 3D printers and materials to propose suitable printers and material to focus on. It compares the different processes for speed, cost, and ease of use. This thesis proposes the proper ways to test the differences and address main known concerns. Using CSUS's and personal resources tests are conducted to compare 3D printed samples to that of cast samples that are approved by FDA and used by the food industry. From the tests it is concluded that 3D printed Polypropylene (PP) is as safe as the cast PP.
