Project: Explore The Inner Ear

IMG_0078_preview_card.jpg
A 3D printed model of a human inner ear (cochlea, vestibule and semicircular canals) that was derived from MRI data of a human cadaver allows students to examine this body part. The model created by neurothing is about 12X actual size. The model was derived from an MRI vrml file from McGill University.

These files are for printing anatomically correct human ear bones (auditory ossicles - malleus, incus & stapes) at about 10X real size. If you open the ossiclesfit.stl file in Rhino (Blender, or other favorite 3d viewer) you will see how they fit together anatomically.

The ear bone files are are based on wrl files from McGill University http://audilab.bmed.mcgill.ca/~daren/3Dear/mid1.html , imported into Rhino3d v 4.0, converted to stl files after some minor mesh repairs.

Project: DNA comb for a Gel Electrophoresis Separation

How can you use the MakerBot to create tools for advanced DNA experiments. In the study of DNA, a process known as Gel Electrophoresis is conducted to separate DNA fragments by charge or size. A Gel Electrophoresis apparatus can be obtained from a number of biological supply companies.


Software used:
  • SketchUp or 3D modeling program of choice
  • MakerWare

Project: STEM/eCYBERMISSION

Use 3D printing to support the eCYBERMISSION Program, a web-based Science, Technology, Engineering and Math (STEM) competition free for grades six through nine. Students compete for state, regional and national awards while solving problems in their community. Students follow the Scientific Method, or Engineering Design Cycle to communicate their solutions online. The Makerbot can be used to create a working prototype or final product.


Software used:
  • SketchUp or 3D modeling program of choice
