3D Printed Character Update 02

Printing and Cleaning/Painting The Parts

So this was a process, printing for all the parts was done on a PLA Extrusion 3D Printer. The head had some problems under the chin area, so I had to re-sculpt that area using Super Sculpey. All the other parts had some support structures on them that I used a demel tool to cut away and excess material and then used a fin grit sand paper to sand away any problem areas.

For the Chest I used a SLA 3D Printer, there were quite a few print failures due to machine problems, in the end I ended up using the best print out of the bunch and ended up re-sculpting the areas that did not print correctly.


















After all the parts were re-sculpted, I used a heat gun to spot heat the new areas of clay, I had to be careful not to overheat areas because the heat could start to melt the plastic from the PLA printed parts.

Once all part were prepared, I used an airbrush with grey acrylic paint to paint all the parts a flay grey color with a nice gloss on the paint to pick up some highlights. I then put the character onto a small base and took photographs of the piece.

All and all I am fairly happy with the results, I do feel like this has given me a good base to work with, there are still some areas that I would like to re-sculpt, but in all honesty, I would really like for all the parts to be printed on the SLA printer (Formlabs) This printed gives you the highest fidelity. The only problem is that we have had so many print failures with the Form 1 and Form 1 +. I am hopeful that most of the printing problems have been fixed with the new FormLabs 2 printer.

3D Printed Character Update 01

I created this little guy to teach some of my students how to model in Maya, then push those meshes into ZBrush and finish detailing. I created a special version of the model that is 3D print ready and hollowed out the model to get it ready for print.





















All parts are prepared and ready to go. I had to use a special feature in dynamesh and negative insert meshes in order to get the shell thickness for the model. In order to do this process just go to a part of the model that you want to punch the hole out of and use B (Brush Menu)>J (Insert Cube) and then hold down the alt key as you draw the cube out. You might want to use transpose master to readjust the cube slightly. Once the negative cube is in place it is time for your to add your shell thickness. Go to the tool menu Tool>Geometry>Dynamesh>Create Shell (You will need to adjust the thickness of the shell using the Thickness slider. I was using a value of 32 for my thickness.) No the only thing left is to decimate the models and scale the appropriately. I was going for a target of around 1 - 1.5 million polys for each printed part. At the size I was printing anything else would be overkill.

High Quality Characters In VR Update 5

I'm currently adding some smaller elements to the sculpt in order to round out the design a bit more.





















Close Up
































I added some larger rope around the character, some smaller beads on the wrist, and some rings that are attached to the main belt as well.

High Quality Characters In VR Update 4

I have finished up all high res modeling on this character. I still like the idea of adding more rope like elements to the design, I added some to his right wrist area and at the top of the belt structure on the top of the character. If there is any more modeling done at this point I would like to add some of these smaller elements.

High Quality Characters In VR Update 3

Here is a high resolution modeling update. I feel that I am about 95 % done with the high res modeling. The results from ZBrush have been pushed into Keyshot for a final render.
Here is a close up for the area with the most changes.
