printing

Solidoodle
black model is 0.3mm pitch. yellow model is 0.1mm pitch.They are PLA model.
UP plus 2
There is a 3D printer called UP plus 2 in my laboratory. It could print models before. But some parts of UP was broken. So when I printed large 3D model, I often failed. And UP is ABS 3D printer.

3D scan

about

I scaned my friend's full body and also I scan my head with 3D sense.

scanning

scanning fullbody

result

I tried to scan other smaller things like a paprika. But I could not scan them bacause sense could not recognize that objects well. And sense is poor at scanning in a messy room. It was not easy for me to understand the range of scanning with sense.

3D print

about

I used "UP plus 2" and "Solidoodle". I made the volonoi model of my head, using the scanned data before.

making

There were some missing parts so I used meshmixer to fix it. There were too many meshes so I reduced mesh with mesh lab.
Autodesk memento let me convert triangle polygon to quad polygon.

I used the 3d data of scaned my head. i tried to edit it with fusion 360. But , It didn’t work. to edit a .obj file with fusion 360, I need to convert it T-spline model. Then, I used Autodesk memento. I sucecceded to convert scaned data of quad polygon. And I read the .obj file with fusion 360 and I suceeded to convert T-spline.

Filling in holes with meshmixer.

Making scanned model I fixed with Meshmixer volonoi.

result

I printed a voronoi model with UP plus 2. But this was too fragile bacause the hole was too small to print model. So I modify the voronoi of the model bigger.

improvement

Reduce the number of the voronoi meshes
