With the advent of manufacturing in Industry 4.0 and consumer demand, there has been a trend of mass customization of products. This customization requirement can only be achieved through the flexibility of manufacturing processes that are tailored to meet the quality standards of customers and the large volume of production in a short time. The increase of the production capacity is achieved through the processes of industrial automation of the manufacture which maintains the increased efficiency for the series production. This study was based on the Design for Six Sigma methodology (DMADV—Define, Measure, Analyze, Design and Verify) in order to determine the soldering process characteristics and how the soldering process can be automatized. When planning the implementation of a collaborative robot in a workstation in the production plant, the following must be taken into account: steps in operations that require the most time for the worker and/or that represent factors of physical and moral overload for him; the use of adequate precision fixing devices, delimitation of work areas, sensors as well as spaces for connecting the workstation to the electrical, hydraulic/pneumatic network and constant cycle time. The proposed solution can improve the productivity of the process by integrating advanced robotics and smart devices into the soldering line.

In metabolic diseases such as phenylketonuria (a rare disease), a very important way to keep the patient healthy is the administration of amino acid substitutes. This dispenser was designed because in other places (except home) for patients, it is very difficult to take the substitute powder due to the custom weight, which depends on the body weight. We designed and made on a 3D printer a graduated dosing device (12 g) which can be used very easily and has all the elements to be transported. In this way, the necessary dose of amino acid substitutes can be administered to patients with phenylketonuria, including infants aged 6 months–1 year, at the kindergarten or any other places with the absence of a food scale. This dispenser is very easy to carry and very useful to patients.
