Fabrication of Freeform Optics
Freeform surfaces on optical components have become an important design tool for optical designers. Non-rotationally symmetric optical surfaces have made solving complex optical problems easier. The manufacturing and testing of these surfaces has been the technical hurdle in freeform optic’s wide-spread use. Computer Numerically Controlled (CNC) optics manufacturing technology has made the fabr...

متن کاملFreeform fabrication of nanobiomaterials using 3D printing
Nanobiomaterials play an important role in nanobiotechnology and have made a great contribution to biomedical research and healthcare. Recent progress in nanobiomaterials has increased demand for multidisciplinary approaches from physical, biological and engineering sciences. Solid freeform fabrication (SFF) technologies are based on layer-by-layer deposition of materials which bring about new ...
متن کاملDynamic Metrology and Data Processing for Precision Freeform Optics Fabrication and Testing
Dynamic metrology holds the key to overcoming several challenging limitations of conventional optical metrology, especially with regards to precision freeform optical elements. We present two dynamic metrology systems: 1) adaptive interferometric null testing; and 2) instantaneous phase shifting deflectometry, along with an overview of a gradient data processing and surface reconstruction techn...
متن کاملSolid Freeform Fabrication of Artificial Human Teeth
In this paper, we describe a solid freeform fabrication procedure for human dental restoration via porcelain slurry micro-extrusion. Based on submicron-sized dental porcelain powder obtained via ball milling process, a porcelain slurry formulation has been developed. The formulation developed allows the porcelain slurry to show a pseudoplastic behavior and moderate viscosity, which permits the ...
