摘要： A method of operating a 3-D printer apparatus includes a tank structure with a bottom wall with a printing area defined above and spaced apart from the bottom wall. A gas permeable liquid within the tank overlays the bottom wall of the tank structure defining a first mobile layer below the printing area. An inhibition liquid within the tank overlays the gas permeable liquid defining a second mobile layer below the printing area. A polymerizable resin overlays the inhibition liquid and flows into the printing area. Positioning of an object carrier controlled such that a lower surface of the object carrier is initially located within the polymerizable resin and within the printing area. Operation of a resin curing device beneath the bottom wall provides light to the printing area polymerizing predetermined portions of the polymerizable resin forming an object attached to the lower surface of the object carrier.
