For 3D printing experts who want to explore the frontiers of 3D printing, the MakerBot Replicator 2X Experimental 3D Printer is a full-featured desktop 3D printer with experimental dual extrusion that is optimized for printing with MakerBot ABS Filament. Create professional-quality, high-resolution prototypes and complex models. The superflat heated aluminum build plate is optimized for ABS and machined for crucial flatness to prevent warping or sagging that can affect build quality. Be ready for cutting-edge developments in ABS filament technology and multi-material 3D printing. Experiment with overhangs and internal structures using MakerBot Dissolvable Filament as solid infill material.
