Pellet extruder
The COGIT AM (Additive Manufacturing) 3D printing extruder is composed of a screw extruder capable of processing high performance polymer pellets such as PEEK, PEKK, PAEK, PEI, PPSU with or without glass or carbon fibres. These materials have very high mechanical performances (90MPa - 200MPa) which allow them to produce complex shaped parts for very demanding sectors such as aeronautics, space, defence or medical. These high performance materials melt at high temperatures (343°C for PEEK) are viscous and very abrasive espacially when they contain fibres. Thanks to its specific design and the choice of treated steel, the COGIT AM print head can print PEEK, PAEK or PEKK pellets filled with fibres. The major advantage is the use of technical polymer pellets which are up to 10 times CHEAPER than the filament spools offered by common extruder.
PEEK pellets ~ 100-120€/kg
vs
PEEK filament ~ 600-1000€/kg
Advantages
