Product Highlights

• The MakerBot Replicator™ is assembled and tested prior to shipment.
• Go big! With a print volume of more than 300 cubic inches, you’ll be making things the size of a loaf of bread. • A new world of color. By choosing the dual extrusion option you can make multicolored objects.
• Low cost consumables. Print in either ABS (what Lego® is made of) or PLA (a bio-material made from corn).
