Automated 3-D Printing Machine Bed Clearing Mechanism 2020-01-1301
The work presented in this paper is based on the senior capstone class project undertaken by the student authors at Kettering University. The main aim of the project was to design an automated bed clearing mechanism for the Anet brand A8 3-D printer. The concept behind the idea was to allow everyone with this brand of printer to be able to print multiple prints without human interaction. The idea started out as a universal bed clearing mechanism, for most brands of 3-D printers. Upon researching into the many different styles and designs of printers, it was apparent that the designs differ too much from each other in order to create a universal product. The student team decided to aim for the most common style of 3-D printer, which the team also had a model to test the design. Due to the size of our team (number of members), they were split in to two sub-teams in order to explore two separate designs and develop the design and testing on both of the designs. Their designs used 3D printed parts, as 3D printing allows simplification of the manufacturing process and better optimized parts. Online data was used to determine the actual strength of these 3-D printed parts, as their properties do not follow classically manufactured plastics. The electronics used to run both designs were Arduino brand microcontrollers. These controllers allowed the team to automate the movement of the system along with servos and small DC motors. The results of all design calculations, CAE simulations, fabrication and testing details will be presented in this paper.
