Title:
THREE-DIMENSIONAL ADDITIVE FABRICATION DEVICE, METHOD FOR CONTROLLING THREE-DIMENSIONAL ADDITIVE FABRICATION DEVICE, AND PROGRAM FOR CONTROLLING THREE-DIMENSIONAL ADDITIVE FABRICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/163405
Kind Code:
A1
Abstract:
The purpose of the present invention is to effectively suppress a reduction in fabrication accuracy based on a difference in thermal expansion coefficient between a three-dimensional additively fabricated object and a fabrication plate. A three-dimensional additive fabrication device is provided with a linear funnel for scattering material of a three-dimensional additively fabricated object. In addition, the three-dimensional additive fabrication device is provided with an electron gun for generating an electron beam. Moreover, the three-dimensional additive fabrication device is provided with a fabrication base material on which the three-dimensional additively fabricated object is to be fabricated. Further, a thermal expansion coefficient of the fabrication base material and a thermal expansion coefficient of the three-dimensional additively fabricated object are the same, or a difference between the thermal expansion coefficients falls within prescribed values.
