New approaches of improving FDM/FFF printing technology

Abstract

This article presents new approaches of increasing the efficiency of FDM/FFF printing technology through the introduction of modifications to the form of filament and to the feeding mechanism. Currently used solutions and innovativeness of proposed concepts are discussed in the paper. A new approach concerning the modification of the filament form was presented in descriptive and graphic way. Moreover, constructional solutions of individual components of the patented (patent PL 224144 B1) filament feeding mechanism including a description of its operation were proposed.
