Case Study of Print Bed Leveling by Bilinear Interpolation in 3D Printers
Keywords:Print bed 3D printer, Leveling, Bilinear Interpolation
Nowadays, 3D printers are a necessity in the industry that especially in areas that require actual work piece. It is a design process with 3D programs. After the desired work piece design has been completed that necessary to prepare a work file divided into layers. It is the process of converting the file into a set of instructions for moving in the X, Y, Z axis. The final step is to feed the batch file to the 3D printer. There are four major problems with 3D printing: leveling the print bed, distance between nozzle and print bed and the print base is not smooth that printed piece incomplete. The research team was able to experiment with automatically adjusting the print bed leveling compared to the conventional method, which is inaccurate due to the tilting of the print bed. This research presents the adjustment of the print bed level by installing the print bed distance sensor. It is the processing of set point a print bed measurement test on the spot. It's linear interpolation versus double linear interpolation. The results show that this method of automatic bed leveling can reduce the problem of first layer printing. The experimental results have a discrepancy of the work piece at 0.0075 %.
