MasterRap i4 DIY Kit
MaserRap i4

MasterRap i4 is an advanced stand alone, print from SD RepRap style 3D printer, With easy access front load filament, anti- grinding on filament  mechanism. It is intend to be a significant upgrade and supersede, replacement of the widely popular Mendel and Prusa i3 which have very  poor performance in speed, precision, structrue stability. MasterRap has exceptional minimum layer thickness as well as stability much better than other DIY 3D printers in the market. With this MasterRap i4, all the unhappy user of those  Mendel and Prusa i3 will enjoy performance gain approach to Ultimaker, and LeapFrog's high end 3D printers that cost in the  $2000 USD class performance with only fraction of cost since we designed and engineered this 3D printer with careful physics, and engineering consideration. We consider top performance as most important priority over anything else. We strike to make MasterRap line of 3D printer equipped the best performance over cost in all level of 3D printer available in the market. Performance, performance and performance is #1 in our design.
