In recent times, the issue of plastic recycling has become one of the leading issues of environmental protection and waste management. So, for that purpose our study is focused only on the recycling of plastic waste. While studying some review papers, we noticed that a high quantity of plastic waste is due to many types of failures which comes from the other resources like plastic bottles, etc., Firstly, we collected plastic waste from different Sources. After that our main aim is to convert plastic waste into a useful product. So, to make plastic waste as a useful product we made a filament extruder. A filament extruder is a machine that converts plastic waste into 3D printer filament with the extrusion on process. The 3D printing market is a well-growing sector. The process involves designing components in a CAD model, followed by 3D printing and assembly. The key elements of the filament fabrication machine include a bottle cutter, hot-end, reel, and controller. The cutter slices the bottle into a continuous strip, which is then softened and shaped by the hot-end into filament form. The reel stores the filament for 3D printing, and the controller manages the hot-end temperature and reel motor. Printable filaments can be made from a variety of thermoplastic materials, including those from recycling. The nozzle is modified to accommodate the filament diameter. The reel assembly involves adding threaded brass inserts, bearings, and a motor-driven pulley system. A customized PCB with a Pro Mini Arduino controls the entire system, with an OLED display providing real-time information. The PCB is housed in a 3D printed enclosure. The fabricated filament is tested by 3D printing benchmark objects, and adjustments to the flow rate and temperature settings are discussed. This paper focuses on a review of the available literature on the production of filaments for 3D printers from recycled polymers as the alternative to present approach of central selective collection of plastics. So, due to this Mechanical and thermal properties were improved by adding different fillers to the input raw material. In addition, commercially available filaments produced from recycled materials and devices which allow self-production of filaments to 3D printing from plastic waste were reviewed. The results indicate the feasibility of using the homemade filament for various projects.
