Title:
HEAT TREATMENT METHOD FOR 3D PRINTED WORKPIECE
Document Type and Number:
WIPO Patent Application WO/2019/109203
Kind Code:
A1
Abstract:
A heat treatment method for a 3D printed workpiece. A wrap in a flowing state is wrapped on the surface of the 3D printed workpiece, and a 3D printed workpiece wrapped with a solid-state wrap is obtained after the wrap to flow is solidified. Heat treatment is performed on the 3D printed workpiece wrapped with the solid-state wrap, so that an amorphous region in the 3D printed workpiece is in a highly elastic state, the internal stress in the amorphous region is released, and the 3D printed workpiece experiencing heat treatment has high size stability. The solid-state wrap wrapping the surface of the 3D printed workpiece effectively limits deformation of the 3D printed workpiece in the heat treatment process, so that the 3D printed workpiece is transformed from unbalanced conformation to balanced conformation in the original outline. The heat treatment method for a 3D printed workpiece is particularly suitable for heat treatment of the 3D printed workpiece that is likely to deform during high-temperature heat treatment, is simple to operate and has remarkable effect.
