Trajectories Generation with Constant Extrusion Rate for Experimentations on AM Techniques and Extrusion Based Technologies

摘要

AM techniques based on material extrusion are currently under experiments in the pursuance of printing new materials related with new printing techniques. For these studies it would be helpful a trajectory with constant feed rate, in order to guarantee a uniform distribution of material with a constant extrusion feed rate. For this purpose a model for trajectories generation is developed exploiting Bezier curves. This model can be helpful for AM experiments and technologies where a uniform material deposition is needed as painting, gluing and sealing. At the end of the paper an example is presented.
