3D head printing bjd



Still a little further advance;) In theory the quality of the photos is better now :)
Here, what we see on the left is the head of robotica printed at 50% of its size at sculpteo and on the right the modeling in patplume done on the printed structure in layer by layer of paper (as seen previously)
The two have clearly nothing in common but it's interesting, it's still two heads, better than I've been able to produce so far.
For 3d printing, there are several services, I took sculpteo because it is in France (for shipping costs) and we can upload the piece to test without buying. The quality is really good and accurate. For this head it cost 12,60 (postage of 5 euros included) against less than 1 euros of material for the head paper and patplume.
As the head is reduced by 50%, I had to activate the automatic filling of fragile areas (if not print there) which makes eyes puffy, filled the hollows, it is rather funny;). To modify it I think I will remold it and take it out in plastiroc or modeling clay.
So for now I have two heads and a hip joint in latex maché paper.
I think that I will model all the pieces in patplume (technique of modeling used higher without layer by layer of paper) to see what it gives. Then make them into papier maché, paper texture print.
This will result in a bjd made of paper maché with texture printed on sheet. Only the head will probably print in 3d and I think the hands in layer by layer of paper or in impression 3d has to see.
Paper Layered printing is interesting to me because it gives me a starting base to model on precise parts like the face. And if you can not afford a 3d impression for precise parts, this is a good alternative and it's fun to do :)
For larger, less precise parts, I use the 3d model and the layered view to model, it is faster and it is enough for me :)
This is what I have for the moment, I will try to move forward a bit.

3D paper mache modeling with scotch tape, patplume and liquid latex




Here, what you see is the 3d left ball hip to 50 percent of robotica. It is not printed layer by layer like for the head and hands.


Instead we used the following files as a plan for modeling a patplume model as accurate as possible :
- the 3d file in blender : https://drive.google.com/file/d/0B_g2mleRq27pYWc2V1M5U2FqdTQ/view?usp=sharing
- the svg file cut up and down, drag and drop in svgviewer :  https://drive.google.com/file/d/0B_g2mleRq27pS0cyNFZ4SGJIN28/view?usp=sharing
- the svg file turned cut right to left, drag and drop in svgviewer : https://drive.google.com/file/d/0B_g2mleRq27pbjUzOFl4UU0zMUE/view?usp=sharing


(patplume version, scotch mold, color test on paper with transparent glue)

Then rub it with food plastic and scotch tape to make a mold.
Fill the food plastic and scotch tape mold with paper mache. Wait until it dries.
Then mix liquid latex and paint to put on the dry paper mache.
Or you can replace latex with paint, glue, and food plastic on the glue to protect and make shine the whole thing :)

If you have holes glue a scotch roll in it.
