3-D Printers for Puppets? #580
I'm starting to love the 3d printing. This was a 1hr 15min print at 200 micron quality.
Here is a print of Eric's head:

Thanks Marc!
I have the units set to mm in maya. I measure based on my 2d sketch, then guess on the thickness, etc. Meshmixer is mm too and so is the actual print software. The only thing that matters is size, doesn't matter how many polygons(basically) or what your edgeflow is like. So it's not like you have to worry about all the stuff when making a cg puppet that will animate.
I do believe in the sculpting software there are measuring tools, there definitely are in Zbrush.

I knew the size i wanted in maya and it wasn't sculpted....I basically did some simple box modeling to get the shape and size I wanted. The finessing really came in the meshmixer software where i could pull and push and soften things. You are a great sculptor, I'm sure you could do great work in Zbrush with just a little practice. I wish I was a better sculptor, but I keep my stop mo stuff simple...so it's working out well so far.

Those look great! Your real world sculpting style shows in your 3-D sculpting. They should make nice puppet heads. When you print them, how do you know how big they will come out? That's one of those things I always wondered because you can zoom in on a 3-D sculpt down to individual pixels in most software. How does the printer see it size-wise? Or are their measurements that show in the software as you sculpt - like a ruler of some sort?

Hey Marc, I don't own Zbrush, but I'm sure a great Zbrush artist could bust out print ready meshes very easily. The stl export I have for Maya is kind of a hack, so bringing it into MeshMixer cleans it up nice for 3d printing. That's what MeshMixer is made for, producing print ready mesh. It also has basic sculpting tools. I'm not great at digital sculpting, or real sculpting, but it allowed me to make my mesh more appealing and add some great details.

The first pic is the versions I made in Maya. Then in meshmixer I made a slot for square tubing to fit on my armature. I added an neck area so the neck goes into the head slightly. I tried making a boolean cut to fit in eyeballs, but decided to just sculpt the eye shape and paint it. I also added a slot for the magnet I'll be using for the mouths.




For the mouths, I am still using flat replacement mouths like my previous short. This time they will be made of plastic with a small bit of metal on the back so it will stick to the front of the mouth area.

Hey that doesn't look too bad. I believe in ZBrush there's a plug-in that comes with it called Dynamesh. I'm pretty sure that is what you'd use in that program to fix mesh issues. From what I can tell yours looks pretty good as a print from Maya. Could you post some digital screen shots?

The only issue with acetone is you probably have to time it so each replacement mouth is in there for the same amount of time. If one melts a little too much it might not register properly. If you are making replacements of course ;)

Small updates on my progress of using a 3d printer to make puppet parts. I've found some great free tools for making models ready to print. I have ok modeling skills in Maya, but there isn't an easy way to get a clean model ready to print. So i've been using a script in maya to export an .stl file. Then from there I import that into Autodesk's MeshMixer, which is sort of a sculpting tool for models that will be 3d printed. If fixes mesh issues and you can also refine your models there. I was able to fix the hair line and beard line with the pinch brush, I added ears, and I made eye sockets.

I had a printer error before the print was done, but here is what it was looking like. This is printed at 200 micron quality, so it was only about 1hr40min print.

I think with the acetone vapor method to smooth the print before painting, it should turn out well.
