Patent ID: 8496863

Claim:
A replication method for producing a smooth object ( 18 , 20 ) having a low surface roughness, comprising the steps of: producing a replication master ( 10 ) by: forming said master ( 10 ) such as to have a desired external surface shape which at least partially corresponds to a counterform of a surface of an object ( 18 , 20 ) to be produced by replication; treating said external surface of said master ( 10 ) to obtain a predetermined surface roughness value; and coating at least a part of said master ( 10 ) with a removable smoothening layer ( 16 ) made of a polymer material which has a flowability such that the top surface of said smoothening layer displays a smaller roughness than the surface on which it is formed and which is soluble after being formed on said master ( 10 ); coating at least a part of said smoothening layer ( 16 ) on said master ( 10 ) with an object material such that the surface of said object ( 18 , 20 ) corresponds to a counterform of said master ( 10 ); and releasing said object ( 18 , 20 ) from said master ( 10 ).
