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

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

AutoDesk Character Generator

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

Import OBJ model to Meshmixer

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

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

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 Figureby Jason Welsh http://www.thingiverse.com/thing:116571

Slice model into parts

•  Use the Plane cut tool to separate limbs •  Use Select brush then Edit > Separate for more

control

Add balls joints to parts

Anna Gerber 3D Sculpting Action Heroes

Add  ball,  use  Transform  tool  to  scale  to  appropriate  size  and  move  into  posi7on  

Anna Gerber 3D Sculpting Action Heroes

Combine  &  Make  solid,  then  use  sculp7ng  tools  to  refine  model  &  blend  joint  onto  part  

Joints for elbows & knees

•  Elbow & knee joints can be created as separate parts if desired, for maximum flexibility

Anna Gerber 3D Sculpting Action Heroes

Add sockets to parts

Anna Gerber 3D Sculpting Action Heroes

Place  ball  (slightly  larger  than  joint  ball),    then  use  boolean  diference  to  subtract  

Hollow out parts

Anna Gerber 3D Sculpting Action Heroes

Also  use  boolean  difference  to    Create  hollows  in  parts  

Add holes for elastic

Anna Gerber 3D Sculpting Action Heroes

Use  a  cylinder  and  boolean  difference,  Use  sculp7ng  tools  to  round  edges  

Split head cap from head

•  Use select brush for precise selection or use slice tool for flat cut

Hollow out head & eyes & add magnet mounting points

Customize parts

•  Use sculpting tools to refine and modify parts

Next steps

•  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
