Abstract

In most FDM 3D-Printers there is no feedback loop to check whether the model is printed correctly. Due to extensive printing times, printers often run unsupervised. Most 3D-Printers actors work with stepper motors, which only know their position relative to a home position. Missed steps or a loose print cannot be detected by the machine. To minimize failing prints, resulting hazards, and to improve printing quality, this work proposes to check the model continuously during the printing process with a camera and if necessary, alert the user. The results show that certain errors can be detected.
