The process...

The first step was to model my face in Anim8or Free 3D Animation Software. Well I'm not quite familiar with the program, having some hard time at the beginning before move into the program. At first import two head pictures (front and side) into scene, which provide a lot of help when modeling. Do only one half of the face and then mirror it.

UV-mapping is the process of applying a texture image onto 3D object. Unwrap the mesh using spherical mapping and next I need is Photoshop skills to to create texture map by using two photo references.

For the next step is unfolding the head with Pepakura, break the model up into printable sections.

After a few print testing (to make sure the big neck is enough to fit my own head), printed 29 sheets of A4 matte papers, which cost around RM45.

Finally it is time to glue my own head together piece by piece, I started with nose.

My front face is almost done.

Using glue wasn't sticky enough, so I change to use double side tape.

The work space is a mess with cutting papers.

The head printed out too dark, especially the cap part, I can't see the texture and most important the fold line. Without the fold line you don't know where something belongs, so I have to take my model as a reference.

Take ages for all the black segment, here's the inside look.

Crazy overuse of double-side tape.

Papers is everywhere, sometime I lost the page and found in the pile of paper.

Almost there, assembling all the big part!

Here's the final result, 2x life-size papercraft head is finished!
