Wanted to use it as a stencil for my sons birthday cake. Printed it on my Raise3D in 24cm diameter. Unfortunately it didn't work out as expected. Perhaps cocoa is too powdery.
alguien puede explicar o hacer un tutorial de como se hace gracias
How did you get such detail in the model?
Well at first the print is fairly large – 24cm – and second it's important to use an image with a high contrast. I picked a portrait with heavy shadow sections, in Photoshop I've increased contrast even more with Levels (important to have 100% black and 100% white sections in the image) and scaled it down to a very small image (don't remember exactly – could have been 64x64px).
On the black areas my polys are real thin. Any idea to make them thicker?
I've used OpenScad and don't remember the exact settings. I'm pretty sure it's possible to set the minimum width. I've just learned that there is a faster version of this thing: http://www.thingiverse.com/thing:310541
Would make sense to use this.
Thanks, I just made black more of a gray.
I wonder if the issue is that the image that appears when the cocoa passes through is a negative image.
While the disc will cast a nice picture shadow, the dark spots are actually the places where the least coca will fall through while the most will fall through the open spots. If you use a negative image of the photo, I believe the results will be closer to what you desire.
Edit: Hmm. I inverted the photo myself and the results weren't what I expected. Perhaps I'm oversimplifying things. Your idea was cool in any case!
I think in principle this stencil should work. Opening are where the cocoa passes thru, so those are the shadow areas. There are several problems applying the cocoa:
A larger grid should work fine.
