Method of manufacturing resin formed product having a leather grain
A method of manufacturing a resin formed product having a leather grain includes: a 3D printing step of inputting printing data to a 3D printer, and printing an intermediate product having an intermediate grain that is a base of the leather grain; and a post processing step of obtaining the resin formed product, which is a finished product, by carrying out post processing on the intermediate product printed in the 3D printing step. A grain height in input data, which is the printing data inputted in the 3D printing step, is greater than or equal to 120% of a stacking pitch in the 3D printing step.
1. A method of manufacturing a resin formed product having a leather grain, the manufacturing method comprising:
a 3D printing step of inputting printing data to a 3D printer, and printing an intermediate product having an intermediate grain that is a base of the leather grain; and
a post processing step of obtaining the resin formed product, which is a finished product, by carrying out post processing on the intermediate product printed in the 3D printing step,
wherein a grain height in input data, which is the printing data that is inputted in the 3D printing step, is greater than or equal to 120% of a stacking pitch in the 3D printing step.
2. The manufacturing method of claim 1 , wherein the grain height in the input data is greater than or equal to 200% of the stacking pitch.
3. The manufacturing method of claim 1 , wherein:
a grain height of the leather grain of the resin formed product, which is the finished product, is from 70% to 130% of the stacking pitch, and
the grain height in the input data is less than or equal to 300% of the stacking pitch.
4. The manufacturing method of claim 1 , wherein:
a grain height of the leather grain of the resin formed product, which is the finished product, is from 70% to 130% of the stacking pitch, and
the grain height in the input data is from 200% to 300% of the stacking pitch.
5. The manufacturing method of claim 1 , further comprising a data preparing step of preparing the input data,
wherein, in the data preparing step, the input data is prepared by expanding actual article data in a grain height direction.
6. The manufacturing method of claim 1 , wherein the 3D printer is an MJF 3D printer.
