Abstract
The present invention provides a method of manufacturing a three-dimensional product having uniform mechanical properties using an SLS 3D printer including the steps of: preparing a mixed powder material by mixing resin powder and glass bubbles, wherein the specific gravity of the glass bubbles is from about 0.8 to about 1.2 times that of the resin powder; supplying the mixed powder material to the 3D printer using a roller; and selectively sintering the mixed powder material by irradiating the powder material using a laser based on 3D data of the product to be manufactured.
Claims6
A method of manufacturing a three-dimensional product having uniform mechanical properties using a selective laser sintering 3D printer, the method comprising steps of:
- preparing a mixed powder material by mixing resin powder and glass bubbles, wherein a specific gravity of the glass bubbles is from about 0.8 to about 1.2 times that of the resin powder;
- supplying the mixed powder material to a 3D printer;
- and
- selectively sintering the mixed powder material by irradiating it using a laser based on 3D data of the product to be manufactured,
- wherein the specific gravity of the glass bubble is adjusted by adjusting a ratio of an outer diameter of the glass bubble and an inner diameter of the glass bubble, and
- wherein the inner diameter of the glass bubble is 81% to 85% of the outer diameter of the glass bubble.
