Filament extruder screw, barrel and nozzle
Artme 3D filament extruder screw and barrel:
Extruder Screw:
Material: SK61 vacuum quenched steel.
Diameter: 12 mm.
Types: Artme 3D offers two main types of extruder screws, which need to be selected when purchasing:
High Compression Screw:
Compression ratio: Approximately 2:1.
L/D ratio (Length to Diameter): 12:1.
Designed for processing shredded 3D printing waste (PLA, ABS, PETG) and certain plastic pellets (PLA optimized for 3D printing, ABS, PP).
Compatibility: Suitable for the "Original Desktop Filament Extruder MK1 to MK3S".
Function: Features a 3-zone design with a compression zone to convey and melt the plastic material.
Extruder Barrel:
Material: Made of 304 stainless steel (RobotDigg's version).
Outer Diameter: 16 mm (specifically for the MK3).
Inner Diameter: 12.15 mm (specifically for the MK3).
Feed Zone: Grooved and chamfered to aid in material intake.
Compatibility: Specifically the "Extruder-Barrel MK3" is suitable for the "Original Desktop Filament Extruder MK3 by ARTME 3D". It's likely similar barrels are used in other MK series extruders, but the exact specifications might vary.
Nozzle M14, 1.5mm
Key Takeaways:
Artme 3D provides specific screw designs optimized for different input materials (pellets vs. regrind).
The screw and barrel are crucial components for melting and extruding the plastic into filament.
The dimensions and compression ratios of the screws are tailored for efficient material processing.
The barrel is designed to work in conjunction with the screw for proper melting and flow of the plastic.
For detailed specifications or if you have a specific model (e.g., MK2, MK3S), it's always best to consult the official Artme 3D documentation or their webshop for the most accurate information. They sometimes offer individual parts for sale, including the screw and barrel.
