Production method of three-dimensional pattern

Abstract

A production method of a three-dimensional pattern is disclosed. First, an adhesive layer is applied on a three-dimensional workpiece. Next, a film is vacuum adsorbed on the adhesive layer so that the film is impressed onto the adhesive layer to form the three-dimensional pattern on the adhesive layer. Finally, the adhesive layer is cured.

1 . A production method of a three-dimensional pattern, comprising:
 applying a first adhesive layer on a three-dimensional workpiece;   vacuum adsorbing a film on the first adhesive layer so that the film is impressed onto the first adhesive layer and a first three-dimensional pattern is formed on the first adhesive layer; and   curing the first adhesive layer.   
     
     
         2 . The production method of a three-dimensional pattern as claimed in  claim 1 , further comprising:
 applying a primer layer on the three-dimensional workpiece before applying the first adhesive layer.   
     
     
         3 . The production method of a three-dimensional pattern as claimed in  claim 2 , further comprising:
 disposing a color layer on the primer layer.   
     
     
         4 . The production method of a three-dimensional pattern as claimed in  claim 2 , wherein the primer layer is a color primer layer. 
     
     
         5 . The production method of a three-dimensional pattern as claimed in  claim 1 , further comprising:
 softening the film before vacuum adsorbing the film onto the first adhesive layer.   
     
     
         6 . The production method of a three-dimensional pattern as claimed in  claim 1 , wherein the first adhesive layer is cured by photo-curing or thermal-curing. 
     
     
         7 . The production method of a three-dimensional pattern as claimed in  claim 1 , wherein the fabrication method of the film comprises:
 applying a second adhesive layer on a substrate;   using a mold to be impressed onto the second adhesive layer to form a second three-dimensional pattern on the second adhesive layer;   curing the second adhesive layer; and   removing the mold.   
     
     
         8 . The production method of a three-dimensional pattern as claimed in  claim 7 , wherein the first three-dimensional pattern and the second three-dimensional pattern are complementary to each other. 
     
     
         9 . The production method of a three-dimensional pattern as claimed in  claim 1 , wherein the material of the three-dimensional workpiece is metal. 
     
     
         10 . The production method of a three-dimensional pattern as claimed in  claim 1 , wherein the material of the three-dimensional workpiece is plastic or carbon fiber.
