METHOD FOR PRODUCING A TUBULAR BODY WITH REDUCED INTERNAL STRESS BY USING 3D PRINTING, AND A TUBULAR BODY WITH REDUCED INTERNAL STRESS

摘要

Disclosed here is a method for producing a tubular body with reduced internal stress by using 3D printing. The tubular body has an outer wall with a stiffening structure extending along at least part of the outer wall. The method sets a printing plane for 3D printing with a 3D printer, and prints a tubular body layer in the printing plane with the 3D printer. The tubular body layer has an outer wall layer and a stiffening structure layer extending in the printing plane along a periphery of the outer wall layer. The stiffening structure layer has at least two portions spaced apart from one another. The method produces an outer wall with a stiffening structure for a tubular body with reduced internal stress.
