Notes:
3DP(three dimensional printing) technology is one of SFF(solid freeform fabrication)technologies which have recently come into a spotlight due to its adaptability to variousapplications. This technology has a great advantage in terms of short fabrication time for aprototype at a low cost, especially when it comes with multi-nozzle inkjet printing technology.However, it has also a disadvantage since it requires additional curing time, after jetting a bindermaterial, and post-processing time in order to increase the mechanical strength of a product. In thisstudy, a novel 3DP process is proposed to overcome slow solidification and elaborate post-processby adopting photo curing method into the conventional 3DP process. Mechanical properties, such astensile and bending strengths, of specimens fabricated with the proposed 3DP process weremeasured and compared with those fabricated with the conventional 3DP process. As a result, it isfound that mechanical strengths of specimens from the proposed novel 3DP process show threetimes higher than those from the conventional 3DP process. Besides, the overall fabrication timewith the proposed novel 3DP process is about two times faster than that with the conventional 3DPprocess, because it does not need additional curing and post-processing time
