Compression molding used preforms made by an extruder/wink cutter or a roller die/die cutter. Pellets or granules of the solid polymer are fed into an extruder. Die forming typically occurs immediately after polymer melt has exited an extruder. Polymer melt from an extruder is fed through an upright die with an annular opening. Both types rely on a separate extruder for each polymer chemistry. The most notable is the Lyman Filament Extruder. Basically the extruder was made part of the molding cycle. Resin, regrind, and most of the additives are combined and processed in a pelletizing extruder. Bucatini can be made at home with a stand mixer and a pasta extruder. The mix is then transferred to a high-shear extruder. Another method is to knead the dough under pressure in an extruder. The first extruder was designed to manufacture sausages in the 1870s. Ultimately, Makerbot replaced the failing extruder with a new version. Kadboli is a similar dish, which is shaped by hand instead of an extruder. Alternatively, they can be mixed directly into an extruder.
