Prototyping and Hygiene Demand Assessment of “CoCuCo” Dispenser

Abstract

Prototyping and Hygiene Demand Assessment of “CoCuCo” Dispenser focusses on the development process of mechanical engineering devices. This includes methods tools and prototyping types. 3D printing is looked into as prototyping method and is explained from the very basic generation of needed data formats until some real life experience reports including improvement suggestions. The Hygiene demand assessment is represented with a very basic wipe test analysis. The needed basic compounds for microbiological growth are mentioned and the possible sources for them. The wipe test mentioned earlier is designed to find one of the possible nutrition sources for mycobacteria. To proof the need for protection of the coffee cu covers, samples of covers are taken from the Tampere city area and analyzed with the wipe tests in TAMKs laboratories. The findings of the wipe test lead to a first conclusion of occasional need for protection. This conclusion is a very weak one due to the nature of test method and needs further back up.
