The MasterRap Dual is intended to be a top performance 3D printer that out beats those main stream big brand well over $1500 USD 3D printers in speed and layer thickness resolution currently on the market. The mechanical construction in this printer allowed the minimum layer thickness down to as small as only 8 micron (0.008 mm) for ultra fine printing that unseen in other printers.  It was designed with solid structural stability with future expansion ability to accept multiple tools attachment modules such as laser engraver, light duty CNC router,..plaster extrusion for draw pattern for exotic application.. We intent to continue future developed this to a exceptional multi-function enthusiastic tool that leading the industry to a next level.
