Additive manufacturing has been established as one of the separate components of Industry 4.0, thanks to its special features such as modeling, simulation, programming, and printing. The gradual introduction of the Industry 4.0 concept and the rapid development of this technology together with the development of suitable materials enabled its use in many areas. The printing of individual components intended for industrial production is no exception. However, the advantages of this technology can be reduced by setting inappropriate parameters or inferior materials, which lead to defects that significantly worsen the quality and functionality of the resulting products. In the presented paper, we have focused on the evaluation of 3D printing of the selected clamping joint type—Shiribasami-Tsugi. It is a type of connection mechanism that allows easy assembly of components without the need for additional connection material such as screws or glues. This element has been analyzed from the point of view of possible defects that may arise using additive technology. This study offered a design of strategies to minimize possible defects and improve the quality of the clamping joint for the product’s production. By using additive technology, it is possible to optimize the consumption of traditional material and reduce the weight of the whole while maintaining the required properties.
