The Construction of 3D PrintingMachine for STEAM Learning

Abstract

We have constructed and developed a Fuse Deposition Manufacturing (or FDM) 3D printer using for teaching and learning STEAM (Science, Technology, Engineer, Fine Art and Mathematics). A body of this 3D printer was applied from recycle materials. There are results to reduce the materials cost of 3D printer for help in teaching and learning. This 3D printer was evaluated for efficiencies by 5 choices: i.e., i) the speed of printing materials (e.g. PLA & ABS), ii) the shapes. It was found that on the change of temperature, the nozzle took 90 seconds to change the temperature from 29 C to 220 C. In case of the maximum size of printing, the 3D maximum size was 130 mm in width, 200 mm in length and height was 160 mm. For a print speed, the 3D printer could feeds materials to print a one cubic-inch model within 22 minutes was found. The accuracy of printing is 2.55%. Finally, this 3D printer could precisely create a cubic, cylindricaland spherical shapes. However, this 3D printer created is still working well at a fair level. There must be further improved in higher performance.
