Abstract
The present invention provides a method of forming a pattern that can form a precise pattern on a variety of media by using powders and provides a pattern-producing apparatus. The method of forming a pattern includes providing a liquid pattern on a surface of a medium, applying a powder to the liquid pattern so as to adhere to the liquid pattern, removing the powdery particles of the powder not adhered to the liquid pattern to give a pattern of the powder, and further applying another powder to the pattern of the powder.
Claims15
A method of forming a pattern, the method comprising:
- providing a film-like liquid pattern of a liquid on a surface of a medium;
- applying a first powder having a first particle diameter to the liquid pattern such that the powdery particles of the first powder adhere to the liquid pattern;
- removing the powdery particles not adhered to the liquid pattern;
- and
- applying a second powder having a second particle diameter that is smaller than that of the first powder to the pattern of the first powder.
A pattern-producing apparatus comprising:
- a provision unit configured to provide a film-like liquid pattern on a surface of a medium;
- a first application unit configured to apply a first powder having a first particle diameter and allowing the first powder to adhere to the liquid pattern;
- a second application unit configured to apply a second powder having a second particle diameter smaller than that of the first powder and allowing the second powder to adhere to the liquid pattern;
- and
- a removal unit configured to remove the powdery particles not adhere to the liquid pattern, wherein
- the powdery particles of the first powder applied by the first application unit and not adhered to the liquid pattern are removed by the removal unit to form a pattern of the first powder;
- and
- the second application unit applies the second powder to the pattern of the first powder.
A stereoscopic object-producing apparatus comprising:
- a provision unit configured to provide a film-like liquid pattern on a surface of a transfer member;
- a first application unit configured to apply a first powder having a first particle diameter and allowing the first powder to adhere to the liquid pattern;
- a second application unit configured to apply a second powder having a second particle diameter smaller than that of the first powder and allowing the second powder to adhere to the liquid pattern;
- a removal unit configured to remove the powdery particles not adhere to the liquid pattern;
- and
- a transfer unit configured to transfer a layer formed of the powders and the liquid pattern on the surface of the transfer member to a stereoscopic object in the middle of formation, wherein
- the powdery particles of the first powder applied by the first application unit and not adhered to the liquid pattern are removed by the removal unit to form a pattern of the first powder;
- and
- the second application unit applies the second powder to the pattern of the first powder.
