The Maker I had my eye on has officially sold out which I believe in this case meant they are no longer available. Sadly this raises the limit on my upcoming Kickstarter as now I have no choice but to go for the bigger, badder model. The Replicator can print in two colors simultaneously, so water-soluble plastics could be printed out alongside the bricks as temporary supports, resulting in wicked-complex bricks that would otherwise try to fall over as I attempted to print.
Another great use of the water-soluble plastic would be a sort of Kinder Surprise deal; mystery objects printed off within a closed sphere (or any shape!) of the dissolving plastic.
