      Are you sure you want to speed up the dry time? Concrete and plaster both harden by absorbing moisture, they do not dry. In fact if you dry them out before fully cured, they will be crumbly.

      > Thanks heaps for the reply. I hadn't thought about the rigidity of the printer. You definitely have a valid point there. I might have to have a bit more of a draw up and post a picture of the printing assy. If I laid the powder down first then there wouldn't be so much of a issue of the powder moving around before it got some binding solution on it to hold it together, would this be correct? Also I could use a heating to decrease the drying time. But I don't know if it would help much. Did you have a look at my pictures I posted?
