A solid imaging apparatus and method employing build material transfer means effective to transfer solidifiable liquid build material from a first side of a radiation transparent build material carrier to a receiving substrate without entrapping air bubbles in layers of transferred solidifiable liquid build material and to cleanly separate the solidified build material from the radiation transparent build material carrier as each layer is formed during the layerwise building of a three-dimensional object. An expandable membrane forming an arcuate dome and a reciprocatible flexible film are employed to effect transfer of the solidifiable liquid build material.

Bubble-free cross-sections for use in solid imaging

A method and apparatus for effectively removing gas bubbles in systems fed to ink-jetting devices. The system removes both small and large-scale gas bubbles from systems that feed materials to ink jet print heads.

Gas bubble removal from ink-jet dispensing devices

A post processing apparatus for automated removal of support material from a three-dimensional objected formed from a build material by selective deposition modeling is provided. The apparatus includes a heated main chamber into which is placed the three-dimensional object with the support material attached and first and second liquid heat transfer medium storage reservoirs. The storage reservoirs reversibly provide liquid heat transfer medium to the main chamber to immerse the three-dimensional object and the attached support material for desired periods of time to meltingly separate the support material from the object.

Post processor for three-dimensional objects

A by-product waste material removal system for solid deposition modeling. As excess build and support material is removed during the build as a by-product waste the removal system accumulates, measures, and releases the by-product waste material into a waste receptacle for disposal. The by-product waste material removal system requires no mechanical vacuum systems and allows operator intervention to remove and replace waste receptacles without interrupting an ongoing build.

Accumulation, control and accounting of fluid by-product from a solid deposition modeling process

A ventilation and cooling system for a selective deposition modeling apparatus dispensing a curable material. The ventilation and cooling system captures airborne contaminants in the apparatus making the apparatus suitable for use in an office environment. A pressure drop is established within the apparatus to assure that all air that enters the apparatus passes through a filter which captures the airborne contaminants before the air is expelled from the apparatus. Sensors are provided to assure that the ventilation and cooling system is function properly, and if not, the apparatus is either shut down or a signal is provided to the operator indicating that the system is not functioning properly.
