Development the low-cost device for production plastic filament for 3D printing using plastic waste.Originality.The paper deals with the research on surveys for development of a low-cost sample 3D plastic filament production machine using modern automatic control equipment.Methodology.The paper proposes one of the possibilities for development low-cost 3D plastic filament production machine controlled by industrial PLC and equipped with human-machine interface.Authors described whole development process starting from description of machine operation principles, control software development and testing process, and finishing with HMI software development and testing and also experimental verification of derived results.Results.Basic concept of the device was defined.The control program was developed using SIMATIC STEP 7 environment from SIEMENS.The HMI interface for filament extruder was created using SIMATIC WinCC software.Tests of the interconnection of the control software developed for PLC control program and the HMI interface was showed reliable results.After the project implementation, we tested the system's functionality.We can say the system works correctly.After appropriate modification and configuration, it could be applied to the physical device for which the project was designed.Practical value.As result, it will be developed low-cost sample of 3D-printer's plastic filament production machine which allowed us to supply 3D printers with filaments for self-consuming needs.Developed device will allow us to produce different kinds of materials such as composite conductive materials and others.References 10, figures 21.
