Exclusive 3D Printed figure for Tsunacon 2012

Like I did last year, I've made an exclusive 3d printed figure for the 2012 edition of Tsunacon (http://www.tsunacon.nl/), a convention in the Netherlands. The figure is based on artwork made by Roos of Tsuna-chan, the Tsunacon mascot character. This year, instead of just one figure, we went with three variations. The figures were given away to the winners of each of the three competitions at the convention.

Santa Girl 3D Printed in Color

I printed out another figure. This one is printed by Shapeways as well (http://www.shapeways.com/model/190101/_santa_girl__figure__full_color_.html), in their "Full Color Sandstone" material (which is basically stuff printed by a ZCorp machine with some additional post processing for extra strength).

The result looks pretty decent, and the figure is quite heavy... It's about 16.5cm high.

I went a little overboard on shading in the texture (which I shouldn't really do, but it's just for testing purposes here), and this resulted in some black spots which seem to blend out quite a bit, so that's something I'll have to avoid, other than that the colors turned out roughly as I expected them to be.

Anyways, here are the pictures! :)

Full Color 3D Print Color Palette

One problem with printing stuff in color using typical CMYK printing ink, is that it's often difficult to get the exact color you want. This color palette shows the color and grayscale range of the fullcolor prints offered by Shapeways. It contains a full hue gradient, to black, to gray and to white, as well as a black to white gradient, and the different base colors seperately. By scanning this color palette, and scanning another color on the same scanner settings, it should be possible to match the right color. The data available on the color palette should be enough to write a small piece of software that interpolates the entire color space in the print, and then get the required on-screen RGB for printing a specific scanned color in this material, which is something I'll work on in the near future.

One thing that is somewhat noticable, is the slight yellowish-ness of the white color. Plotting the hue values on the hue side a bit, shows how yellow/green is very saturated, while inversely the printed cyan is not as saturated as the original onscreen cyan. Note that this plot is heavily dependent on scanner type and settings, so observations may vary.


If you want to see for yourself what the colors look like, you can get one too.

Personalized 3D Printed Keychain

I did some revisions to the 3d printed keychain, which I previously used to make the video with the hammer.

Received the new 3d print in the mail last week, and put it on the ring with my keys. At the time of writing this, it's still intact, with only some minor scratches that you'd normally have on any plastic keychain.

Watercoloring Shapeways' White Strong & Flexible

Coloring test on Shapeways' White Strong & Flexible 3D printing material, using Winsor & Newton watercolors and Letraset ProMarkers. With watercolors it is possible to make soft gradients between colors, as well as sharp edges. Markers blend slightly, giving softer edges, and can be used to make gradients as well, similar to how they react on paper. Watercolors can be washed out of the printed object almost entirely using water, marker colors don't change at all under water.

Shapeways' Full Color 'Sandstone' Strength Test

Here's the video where I fail to break the thing in two by hand, and therefore resort to a hammer. Spoiler: the printed thing does not survive. Printed by Shapeways in the material they call Full Color Sandstone. The color is printed 1mm deep, and at 3mm thickness it's quite strong enough for normal handling.
