Beschreibung
Zusammenfassung:	Apparatus and method for forming a three-dimensional object. The apparatus includes a platform on which the three-dimensional object is formed. The apparatus includes an oxygen soluble liquid having a build surface. The build surface and the platform define a build region therebetween. The apparatus includes a photosensitive liquid disposed on the oxygen soluble liquid. The density of the oxygen soluble liquid is greater than the density of the photosensitive liquid. The apparatus includes an optically transparent member. The optically transparent member supports the oxygen soluble liquid. The apparatus includes a radiation source configured to irradiate the build region through the optically transparent member and the oxygen soluble liquid to form a solid polymer from the photosensitive liquid. The apparatus includes a controller configured to advance the platform away from the build surface.
