The combination of parameters in the product printing process with Polylactic Acid (PLA) material using the ANET ET4 PRO 3D printer is carried out to obtain optimal parameters to produce accurate dimensions in the printing process. The most popular type of 3D printer is the Fused Deposition Modeling (FDM) type, which uses melted plastic raw materials to form products. In the existing printing process, the accuracy of the dimension is the main problem owned by users of this 3D printer technology. Especially when these products have to be assembled into a mechanism. The resulting accuracy is greatly influenced by the selection of process parameters used during the printing process. The parameter optimization process using the Taguchi method was chosen because this method is very good at overcoming deviations from the target so that the best quality of the product can be achieved. The optimization process of this parameter will be carried out using a ring-shaped specimen with an outer diameter of 30 mm, an inner diameter of 20 mm, and a height of 20 mm. This deviation in the size of the inner diameter of the ring would be the reference for measuring the quality of the printed object. From the experiments, the most optimal level values for each factor were as follows: the Nozzle Temperature was 200 °C, the Bed Temperature was 62 °C, the Room Temperature was 34 °C, the Infill Percentage was 40%, the Layer Height was 0.25 mm, the Printing Speed was 20 mm⁄s.

Recycling plastic waste is one way to minimize the negative impact on the environment. The use of additive manufacturing which speeds up the prototyping process and product design currently uses a 3D printer with ABS and PLA filament materials. Remaining filaments and unused parts/prototypes, or products that have been manufactured with actual materials will be discarded. This causes waste for the environment. The use of recycled filament for 3d printing machines is one way to deal with plastic waste, besides that the use of recycled filament is a way to reduce the cost of plastic filament. Recycled plastic filament is used for 3d printer machines with the Fused Deposition Modeling (FDM) type. In this method the plastic filament material is melted and then extruded according to the desired pattern. In this study the results of the prints were tested using the tensile test method. Parameters used, print temperature, layer height, print speed. Response data analysis uses the Response Surface Method (RSM) with the Box-Behnken type. The results of the tensile test data were analyzed using Analysis of Variance (ANOVA). Based on the results of the ASTM D638-10 type 1 tensile test analysis, the print temperature parameter is 2600C, the layer height is 0.12 mm and the maximum print speed is 50 mm/s.
