Title:
固体モデルのラピッドプロトタイピング方法
Document Type and Number:
Japanese Patent JP4107686
Kind Code:
B2
Abstract:
Data corresponding to a desired shape of a prototype is transmitted to a rapid prototyping system. The system calculates a sequence for extruding flowable material that thermally solidifies so as to create the desired geometric shape. A heated flowable modeling material is then sequentially extruded at its deposition temperature into a build environment that maintains the volume in the vicinity of the newly deposited material in a deposition temperature window between the material's solidification temperature and its creep temperature. Subsequently the newly extruded material is gradually cooled below its solidification temperature, while maintaining temperature gradients in the geometric shape below a maximum value set by the desired part's geometric accuracy.
