If you’re in the market for a 3D printer, you can now buy one from one of the Web’s favorite discount vendors. Monoprice has announced its Dual Color Extrusion 3D Printer. Available for preorder now, the $1,200 unit is available to ship by the end of the month. It’s the Web retailer’s first 3D printer. While there are plenty of 3D printers available for $1,000 or less, the new Monoprice model is one of the more affordable models capable of handling two-color creations.
