Easy Printing Experience:
-
Print with a 0.6mm hardened steel nozzle
-
Prints similar to PLA
-
Minimal to no warping
-
Ensure the filament feeds straight into the extruder
-
Less hygroscopic than PLA
-
Do not dry this filament—drying will degrade the binder
Fully Sinterable:
After printing, your part can be fired in a furnace to become 100% metal.
Applications:
-
Prototyping
-
Functional metal parts
-
Wear resistant parts
-
Aerospace and automotive research
-
One-off and short-run manufacturing
-
Reducing or eliminating tooling and machining costs
All print just like PLA on most open-architecture 3D printers.
