Joe Larson

Joe Larson, known online as "the 3D Printing Professor," is one part artist, one part mathematician, one part teacher, and one part technologist. It all started in his youth, doing BASIC programming and low-resolution digital art on a Commodore 64. As technology progressed, so did Joe's dabbling, eventually taking him to 3D modeling while in high school and college, and he momentarily pursued a degree in computer animation. He abandoned that and instead became a math teacher, and then moved to software development for 10 years before returning to education, teaching technology in college. When Joe first heard about 3D printing, it took root in his mind, and he went back to dust off his 3D modeling skills. In 2012, he won a Makerbot Replicator 3D printer in the Tinkercad/Makerbot Chess Challenge, with a chess set that assembles into a robot. Since then, his designs on Thingiverse have been featured on Thingiverse, Gizmodo, Shapeways, Makezine, and other places. He currently produces weekly videos about design for 3D printing on his YouTube channel, http://www.youtube.com/user/mrjoesays.

Posing the bear

This bear is a great looking model, but it's not printable the way it is. Keeping in mind the overhang and bridging rules from Chapter 1, Design Tools and Basics, the bear needs to be put in a pose that will print. The legs are a clear problem so the bear will be made to sit on a box.

Use the combo box at the bottom of the 3D View panel to switch from BearSkin to Object Mode.

  1. Add (Shift + A) a cube to the scene.

  2. Scale (S) and position (G) it so it is under the bear's hips.

  3. Select (right-click) the hip bone in the armature.

  4. Rotate (R) the hip bone around the x axis (X) to make the bear sit.

  5. Select (right-click) the calf bone.

  6. Rotate it (R) around the x axis (X) to bend the knee.

  7. Repeat with the other leg.

  8. Select (right-click) and Rotate (R) the cube around the z axis (Z).

  9. Position (G) the cube in the xy plane (Shift + Z) to put it properly under the bear.

  10. Select (right-click) the bone through the body.

  11. Rotate (R) it slightly around the x axis (X) to get the bear to lean back a little...
