Today I had a talk with Alessandro Sambini, Joris v Tubbergen and others about an art project which is centered around creating a life-size statue of a person using my gray-scale halftoning technique.
We need to do some initial experiments to see how well the techniques adapt to higher layer heights and bigger nozzle sizes to see whether the project will go through, but I have full confidence.
I’ve published a paper about gray scale printing in the journal Computers & Graphics
3D hatching: linear halftoning for dual extrusion fused deposition modeling.
The accepted manuscript can be found here: https://arxiv.org/pdf/1805.01375.pdf
The final paper can be found here: https://dl.acm.org/citation.cfm?doid=3083157.3083163
This is an extension of the conference paper called
3D hatching: linear halftoning for dual extrusion fused deposition modeling
Texture printing reveals to be a promising technique.
It requires a very good XY calibration, however.
Still need to calibrate the grayscale colors for it to be perfect….
