The main aim of the project was to technically develop an adaptor that can be fixed to the aerosol bottle and to develop a suitable ergonomic mask in line with the ideas of our partner. The developed product consists of several components (adapter, ergonomic mask and silicone padding for comfort). The design of these components had to consider the manufacturing technology and dimensions of the cylinders. A functional adaptor was created where the used material and its mechanical properties (e.g. flexibility) were crucial. The mask and silicone part attached to it had different material properties, which have been tested and implemented in different versions. Additive technologies played an important role in the design phase. All prototypes have been manufactured by FDM or SLA printing technology.
