3D Sculpting Action Heroes
- 1. 3D Sculpting Action Heroes Anna Gerber Anna Gerber 3D Sculpting Action Heroes
- 2. Outline • Tonight: 3D Sculpting Action Heroes – Generating base models – Slicing into parts & adding joints – Customizing via 3D sculpting tools • 3D Printing Action Heroes – April 17th – Preparing parts for 3D printing – 3D printing – Cleaning up 3D printed parts • Adding electronics to 3D printed Action Heroes – April 24th – Make them interactive – Electronics & coding Anna Gerber 3D Sculpting Action Heroes
- 3. Generating Base Models • Use character mesh generators to save time: • Make Human – Free & Open Source – http://www.makehuman.org/ – License of generated characters: CC0 • Mixamo Fuse (Now owned by Adobe) – https://www.mixamo.com/fuse – Free preview requires Adobe account – Royalty free use of generated models allowed for 3D prints but you cannot sell the generated models directly • AutoDesk Character Generator – http://area.autodesk.com/products/charactergenerator – Free & Paid Subscription service – Unrestricted usage of generated models Anna Gerber 3D Sculpting Action Heroes
- 4. Other sources for models • Thingiverse – http://www.thingiverse.com/ – Use Creative Commons licensed models • Model Resource – From games, for personal use only – http://www.models-resource.com/ • Create a model of someone's head – Use 123DCatch app to create model from photos • http://www.123dapp.com/catch – Use a Kinect & Microsoft's 3D Scan app • (Windows only) • http://microsoft.com/3d Anna Gerber 3D Sculpting Action Heroes
- 5. MakeHuman Anna Gerber 3D Sculpting Action Heroes
- 6. Fuse Anna Gerber 3D Sculpting Action Heroes
- 7. AutoDesk Character Generator Anna Gerber 3D Sculpting Action Heroes
- 8. Export the character model • Export model as OBJ format model • AutoDesk Character Generator exports FBX – convert these to OBJ using AutoDesk FBX Converter or other 3D software • Online converter: – http://www.greentoken.de/onlineconv/ • We're using AutoDesk Meshmixer for 3D Sculpting: – http://www.meshmixer.com/ – Free software for Windows, Mac or Linux • Alternative sculpting programs include Sculptris & Z- Brush Anna Gerber 3D Sculpting Action Heroes
- 9. Import OBJ model to Meshmixer Anna Gerber 3D Sculpting Action Heroes
- 10. Scales You'll need to scale your model to Action Hero size. Popular scales: • 1:4 (18") common for collector dolls • 1:6 (12") i.e. original G.I. Joe scale • 1:10 (7") currently the most popular size • 1:12 (5 -6") 90s Action Toys • 1:18 (4") kids action figures e.g. Star Wars We'll use 1:10 scale i.e. around 15 – 18 cm tall Anna Gerber 3D Sculpting Action Heroes
- 11. Scale Model in Meshmixer • Adjust scale via Edit > Transform so that the model is around 15 – 18 cm tall • Red = X • Green = Y • Blue = Z Anna Gerber 3D Sculpting Action Heroes
- 12. Ball Joints • We're using a ball joint system: – Ball joints fit into sockets – Parts held together with elastic • Alternative joint systems include: – Print-in-place ball joints – Snap together joints e.g. see Open Source Action Figure by Jason Welsh http://www.thingiverse.com/thing:116571 Anna Gerber 3D Sculpting Action Heroes
- 13. Slice model into parts • Use the Plane cut tool to separate limbs • Use Select brush then Edit > Separate for more control Anna Gerber 3D Sculpting Action Heroes
- 14. Add balls joints to parts Anna Gerber 3D Sculpting Action Heroes Add ball, use Transform tool to scale to appropriate size and move into position
- 15. Anna Gerber 3D Sculpting Action Heroes Combine & Make solid, then use sculpting tools to refine model & blend joint onto part
- 16. Joints for elbows & knees • Elbow & knee joints can be created as separate parts if desired, for maximum flexibility Anna Gerber 3D Sculpting Action Heroes
- 17. Add sockets to parts Anna Gerber 3D Sculpting Action Heroes Place ball (slightly larger than joint ball), then use boolean diference to subtract
- 18. Hollow out parts Anna Gerber 3D Sculpting Action Heroes Also use boolean difference to Create hollows in parts
- 19. Add holes for elastic Anna Gerber 3D Sculpting Action Heroes Use a cylinder and boolean difference, Use sculpting tools to round edges
- 20. Split head cap from head • Use select brush for precise selection or use slice tool for flat cut Anna Gerber 3D Sculpting Action Heroes
- 21. Hollow out head & eyes & add magnet mounting points Anna Gerber 3D Sculpting Action Heroes
- 22. Customize parts • Use sculpting tools to refine and modify parts Anna Gerber 3D Sculpting Action Heroes
- 23. Next steps • Drop into the Fabrication Lab or download Meshmixer at home to continue working on the models: – http://www.meshmixer.com/download.html • If you will be participating in the 3D printing workshop, please bring your models along then • We'll be focusing on preparing the models for printing, exporting to STL, and printing them on the 3D printers Anna Gerber 3D Sculpting Action Heroes

Notas del editor
- Intro section: 10 minutes Introductions, housekeeping In this hands-on two hour beginner’s class we’ll:Generate customised 3D human models using MakeHuman Slice up a 3D model and add articulated joints using Meshmixer’s slice and merge tools Use Meshmixer’s 3D sculpting tools to customize 3D parts
- We'll cover how to sculpt the figure It actually takes longer than 2 hours to create a completely custom figure You are welcome to come into the Fab Lab during opening hours to keep working on your models, or you can download the software at home
- Other alternatives exist for scanning with Mac
- Note how "blocky" the models are – low poly
- Print in place very cool in principle, but difficult to clean up parts / paint etc
