Explore the fundamentals and technology behind plastic extrusion for 3D printer filament in this comprehensive 35-minute video. Delve into the workings of screw extruders, understanding how plastic pellets are fed, melted, and extruded through a die to create 1.75 mm filament. Learn about the cooling, measuring, and spooling processes, as well as the molecular structure of polymers and how it affects extrusion and printing. Witness the extrusion of various materials including PLA, ABS, PETG, HIPS, and composite materials like carbon fiber reinforced ABS. Gain insights into die and screw design, barrel heaters, and the economics of filament extrusion. Discover the differences between semi-crystalline and amorphous materials, and how crystallinity impacts warping and opacity. Follow along as the video demonstrates purging, cleaning, and extruding different types of filaments, providing a thorough understanding of the entire 3D printer filament production process.
