Selective deposition modeling with curable phase change materials |
摘要 |
A selective deposition modeling method and apparatus for dispensing a curable phase change material. The dispensing temperature of the material is set at or less than a thermally stable temperature value for the material in which the reactive component of the material remains substantially uncured when held at the temperature for a desired time period. The dispensed material is provided with an environment that enables the material to solidify to form layers of the object. The solidified material is normalized to a desired layer thickness and is then cured by exposure to actinic radiation. In a preferred embodiment a UV curable phase change material is dispensed at about 80° C. and has a viscosity of about 13 to about 14 centipoise at this temperature. The cured material provides substantially increased physical properties over thermoplastic phase change materials previously used in selective deposition modeling.
