Pancreatectomy in a 45-year-old woman showed, after pathologic analysis, an epidermoid cyst originating from an intrapancreatic accessory spleen. This mass consisted of parenchymal and cystic components. It is important to note the relation between the splenic parenchyma and the parenchymal component of the mass for the differential diagnosis of a cystic mass in the pancreatic tail.

This research deals with the development of a simple and practical method for manufacturing high-aspect-ratio (height/width) micro-parts and three-dimensional micro-parts. The desired product shape is obtained by writing along the contour of the product on the surface of a liquid photopolymer using a focused UV laser beam. The written pattern then becomes solid so as to produce a solidified polymer mold or structure. This paper examines the effect of physical parameters such as wavelength of laser beam, focal length of lens, absorption coefficient and writing speed on the shapes of the solidified polymer. The examination is done theoretically, and the optimum conditions to produce high-aspect-ratio micro-parts and three-dimensional micro-parts are also verified. Using these conditions, various microstructures are produced.

This research work deals with the methods for manufacturing high aspect ratio micro mechanical parts by using UV photopolymer. In the first method, polymer structures are produced using a mask-based method. And the second i s a direct focused UV laser beam writing method. The irradiated portion of the liquid photopolymer i s solidified and i t becomes a polymer structure. At first, the solidified shape of the polymer i s examined in each method and the optimum conditions to produce high aspect ratio structures are verified. Next, the comparison of the both methods are made. At l a s t , examples o f structures that have been produced using the methods described are shown.
