Thesis Statement
Abrasion Holography is a technique that creates pseudo-3d images using the anisotropic properties of curved grooves in a reflective material. We modified a 3d printer to create these images by attaching an engraving tool to the printing head, and wrote software to create groove patterns from stl 3d models.

Abrasion Holography is a technique that creates pseudo-3d images using the anisotropic properties of curved grooves in a reflective material. We wrote software to create groove patterns from stl 3D models. Then we used an engraving tool attached to the head of a 3D printer to engrave the patterns of pieces of plastic.
