Disclosed is a three-dimensional modeling apparatus (10) that builds up three-dimensional objects in a heated build chamber (24) by dispensing modeling material from a dispensing head (14) onto a base (16) in a pattern determined by control signals from a controller (140). The motion control components (18, 20) of the apparatus (10) are external to and thermally isolated from the build chamber (24). A deformable thermal insulator (132) forms a ceiling of the building chamber, allowing motion control of the dispensing head (14) in an x, y plane by an x-y gantry (18) located outside of and insulated from the build chamber (24). In the preferred embodiment, a material dispensing outlet (66) of the dispensing head is inside the chamber. Thermal isolation of the motion control components from the build chamber allows the chamber to be maintained at a high temperature.
A three-dimensional modeling apparatus comprising a heated build chamber in which three-dimensional objects are built, a base located in the build chamber, a dispensing head for dispensing modeling material onto the base, the dispensing head having a modeling material dispensing outlet inside of the build chamber, and an x-y-z gantry coupled to the dispensing head and to the base for generating relative movement in three-dimensions between the dispensing head and the base, characterized in that:
