This paper aims at finding some lessons applicable to successful implementation of ‘The 3D Printing R/D Project’ through both examining the process of adopting overseas industrialized housing production technological knowhow by home builders during the 1970's~1980's period and thereafter until now the various efforts to adjust the technologies efficiently to the Korea‘s unique situation. Some meaningful lessons can be summarized as follows; Ⅰ) Deep understanding of 3DP technological know-why along with its inheritance, Ⅱ) Readjusting of R/D period and goals(cf. Global leader Winsun's 15 years experiment), Ⅲ) Restructuring for more collaborative R/D B&E system among participating researchers Ⅳ) Fostering 3DP expert-engineers and technicians from the early stage, Ⅴ) Clearing legal barriers in users' adopting 3DP methods necessary, Ⅵ) Development of appropriate building material besides concrete. Therefore, it is highly recommended that the above-mentioned 6 lessons positively accepted and applied to the Research Implementation Plan in due course, especially by KICT consortium and KAIA under the guidance of Ministry of Land, Infrastructure and Transport.
