**4. Conclusions**

Early-age creep and shrinkage property tests were performed on the prismatic specimens at the age of 28 days. The long-term property tests were carried out for 28 days. Prior to the long-term tests, compressive strength was determined for the cast and printed specimens. Following conclusions are:
