Abstract

One of the technologies that are developing rapidly is 3D printing. 3D printing machines can create objects easily, quickly and in detail. There are three main steps that a 3D printing machine goes through, namely design, printing and finishing. 3D printers using polylactic acid are widely used in various types of fields such as industrial machinery, spacecraft, consumer goods, electronic components, vehicles, medical industry, toy industry and others.In this research, we succeeded in making an educational game tool called Tetris with the 3D printing method using polylactic acid filaments. The process of consistently creating 3-dimensional objects from digital files by arranging many layers of thin metal in succession is called 3D printing. Using additive manufacturing technology, 3D digital designs are turned into virtual products by sequentially depositing metals. 3D printing provides reasonable feasibility to meet various parameters based on the engineering arena. By utilizing the advantages of PLA material, which has good tensile strength, good surface quality, is available in various colors and user-friendly, educational game tools are produced that have the advantage of being attractive, light, strong and easy to play. That way, making educational game tools using 3D printing made from PLA can solve the problems with previous educational game tools, which are not easy to play and less attractive to early childhood. Educational games that have been made in this study can be used as a platform for learning children at the kindergarten to elementary school levels. The way to play this educational game Tetris is by attaching shapes to the main part of Tetris and matching them with other shapes, just like playing a puzzle where each shape that is installed must match the other shapes

Highlights

One of the developing technologies, namely 3D printer technology with machines for manufacturing products, can be done quickly and in detail
To help the learning system, an educational game tool design is made in accordance with the development of science and the curriculum that applies to early childhood education
Educational aids based on Science Technology Engineering Math (STEM) are anything that can be used as a means or a game tool that contains an educational value based on STEM and can develop all aspects of children’s abilities, both from the surrounding environment and equipment that is deliberately made [6]

Summary

Introduction

One of the developing technologies, namely 3D printer technology with machines for manufacturing products, can be done quickly and in detail This 3D printer using polylactic acid can print prototypes, prototypes/modeling, game tools for education, jewelry models, health support tools, product design, children’s toys and various needs to print shapes in 3 and 4 dimensions [1]. This can be seen from human needs, which are getting more and more complex over time, so we need a tool that can produce objects that are in accordance with the design made with a similarity close to 100 % of the design made, short time, and low cost. Educational play tools are a means that can stimulate children’s activities to learn something without the child realizing it, either using modern technology or simple technology even traditional ones [7]
