More on the continuing Moai story…   After receiving his first 3DP’d Moai, Archeology Professor Carl Lipo has been inviting us to participate in various activities.  About a month ago, he sent us a request to make more Moai.   In fact, he really wanted somewhere between 20-25 statues.   He was running a conference/briefing and he wanted to explain the power of Additive Manufacturing and it’s place in the world of Archeology.   With a brief pause, we said “Sure, we can do that…”

Each  Moai stands 7.5 inches (~190 mm) tall.   A build with two Moai in the bed takes about 3.5 hours.  While there are many options for post-processing, we gave them the “dip” into the waxer.

After we shipped a box of 23 Moai to Long Beach, California, I sent Carl a request to photograph them set up like a Terra Cotta Army.   Carl’s response is shown below:

“Carl, How did your conference go?”

“It went very well – the moai models provided the ideal means for demonstrating how
the statues must have been moved. By manipulating the models on a table its easy to
see how just a small amount of energy can set the statues in motion and that the
edge of the base provides a surface for rolling the weight across. This is
consistent with the road surfaces that tend to be concave as well… So the 3D
models did exactly what I had hoped!”

    From the images, the results of your printing look very rough compared to printing with original Z materials.

    Are your self printed objects smooth or are they bumpy?

      Dear MCJ,

      Thanks for checking in directly rather than spreading untruths about us in DIY 3DP group.

      The powder is at least as fine as the brand name. I think the finish is generally similar if one compares 400s to 400s and 300s
      to 300s as the machines have different DPI values.

      We were given an extra challenge to make them look weathered. You will notice that we have a couple with spots missing
      on them (like pieces had fallen out). Also, we made special multi-material powder to produce some of the color variation.
