Abstract
Disclosed is a method for treating objects produced by an additive manufacturing process which have at least one surface formed from a polymer with a glass transition temperature of at least 120° C., and preferably are formed from such a polymer, and in which the surface of the object is brought into contact with an organic or inorganic solvent. By such a treatment, the surface of the objects can be smoothed and relevant mechanical properties can be improved. Further disclosed are three-dimensional objects produced according to such a method and to the use of organic or inorganic solvents to reduce the surface roughness and/or to improve the mechanical properties and/or the chemical resistance.
Claims13
A method for treating a three-dimensional object produced by an additive manufacturing process, comprising:
- bringing the object into contact with an organic or inorganic solvent, wherein at least a surface of the object is formed from a polymer that has a glass transition temperature of at least 120° C.,
- wherein the bringing the object into contact is carried out in a plurality of stages, wherein each stage uses a different solvent as the organic or inorganic solvent.
