The MakerBot Replicator Mini makes solid, three-dimensional objects out of PLA Filament. First, use MakerBot Desktop to translate 3D design files into instructions for the MakerBot Replicator Mini. Then transfer those instructions to the MakerBot Replicator Mini via USB cable or over a Wi-Fi network. With the touch of a button, the MakerBot Replicator Mini will melt MakerBot PLA Filament and squeeze it out onto the build plate in thin lines to build your object layer by layer. This method of 3D printing is called fused deposition modeling.
