A study on BRP(Building Rapid Printing) technology is in an initial stage although general 3d printers are being developed in a great speed and with fruitful outputs. Even some laboratories in advanced countries have difficulties in their research due to many technological restrictions and have not produced a practical output yet. This paper proposed distinct directions in which the research of this aera should be developed and this manifested four areas - printing speed, reinforcing tech, material tech and nozzle tech and those areas were proposed with concrete development alternatives and objects.
