MakerBot created a stir at CES 2015, with the announcement of new filaments that have the look, weight and feel of metal, stone or wood for more varied, realistic and attractive 3D prints. MakerBot PLA Composite Filaments
also share some of the properties of these natural materials. For example, the Maple filament shown at CES can be sanded, stained and finished; the iron filament is magnetic; and over time the bronze filament develops an attractive patina. The new composites for MakerBot Replicator Mini Compact, Desktop and Z18 3D printers are due out later this year.
