The Replicator is the most easy-to-use 3D printer in The Garage. It has simple software, a simple interface, and is fairly dependable for 3D printing.[makerbot replicator pic]
It is a FDM (fused deposition modeling) 3D printer that uses an extruder to heat a plastic filament spool and deposit it onto the build platform in layers. This is the most common type of printer at The Garage, and at most makerspaces.
