Business card - Layer selective colour 3D printing
by RichRap, published
Description
A business card seemed a suitable object to start with as I could place things and text onto it and vary the height of each object.

Over the top. This is really imaginative and now skilled too!
Because he uses Skeinforge 41 he can just add up the lengths of filament indicated by each layer in the Gcode. ( All the E moves are actual lengths of filament being used ). So using Grep he adds up all the E values from each Layer and cuts a length of filament to match.
*um yeah* I wasn't too lazy. I read the blog. He says he used grep to separate out the layers, but doesn't indicate how to figure out the lengths. He did not explain that part very well in his blog. I wonder, did you guys read the blog post?

How exactly did you figure out the lengths of filament to join. You used grep to split out the layers, then how did you figure out how long a filament would cover each layer?
I don't know how he did it, but I might skeinforge the object from say layers 1-10 (carve tab) and read off the mass of plastic. Then make the first segment weight slightly more. Then skeinforge layers 11-14 or whatever. Continue to build the joined filament in this manner. Just make sure each color layer is at least 2 (probably
&
gt;=3) actual layers to take up some of the inaccuracies. Finally reskein the whole object and print.
I would also be curious in how RichRap did it though.
