3D printing technology, also known as Additive Layer Manufacturing, is a technique for creating three-dimensional objects by adding materials to form the desired product. 3D printing technology supports workers to help them in their work because it can turn inspiration into tangible form. One of the rapid prototyping technologies that are often found in the market today is the FDM (Fused Deposition Modeling) technology. The characteristics of components produced using the FDM method are high strength, relatively good precision, do not require finishing and can save raw materials because no residue is produced. The 3D printing process and performance depend on various important parameters such as manufacturing time, dimensional accuracy, surface quality, and mechanical characteristics of the part being made. The research was conducted to determine the impact strength of 3D printing products using PETG (Polye Terephthale glycol) filaments which were influenced by process parameters such as bed temperature (°C), nozzle temperature (°C), print speed (mm/s). The method used is the taguchi method. This method is used in improving the quality of experimental designs to find the main causes that are very dominant in quality characteristics, so that quality characteristics are obtained. With this method the best combination of product units and process units is obtained at a high level of uniformity to achieve best quality characteristics at low cost. To measure the material's resistance to shock loads, it uses impact testing. process parameters that have the greatest influence on the strength of the impact test, namely bed temperature (80°C), nozzle temperature (230°C) print speed (40 mm/s). 8 with the same value of 4.591 Jmm2 and for the 1st lowest value with a value of 3.374 J/mm.
