Pellet-based extruder uses a screw to feed, transport, and melt the material inside a barrel and forces the material out to be extruded at desired temperatures. Despite pellet extruder being complex, it is used in additive manufacturing because it has several advantages. This study presents the review of designs of pellet extrusion systems.

A typical extruder used in the MatEx includes three extrusion components (Fig. 1) [2]: a cylindrical liquefying tube with a length of l t and a radius of r t; a conical connecting tube with a length of l c; and a cylindrical print nozzle with a length of l b and a radius of r b.Since the cylindrical tube is much longer than the conical one, for simplicity, …

This is the second time I've encountered an issue where the AMS stage 1 motor will not feed filament all the way to the extruder on my X1C. It stops about 1-inch short of the extruder, retracts, tries again, and keeps stopping at the same point (until it gives up).Even if I disconnect the PTFE tube running to the extruder, the AMS stops …
