Abstract

The instant invention relates to a method for changing characteristics of a plastic component, wherein a medium is introduced into the plastic component, which encompasses a porosity and wherein the medium forms a homogenous compound with the plastic component by at least partially dissolving the plastic component.

Claims

exact text as granted — not AI-modified
1 . A material system comprising: a plastic component, wherein the plastic component has a porosity, and
 a medium for introduction into the plastic component, wherein the medium includes at least one substance capable of at least partially dissolving the plastic component and forming a homogeneous compound therewith;   wherein the plastic component is produced by means of three-dimensional print processes.   
     
     
         2 . The material system according to  claim 1 , wherein the medium includes a polymerizable material so that the medium is capable of a solidification after introduction in the porosity of the plastic component by means of polymerization. 
     
     
         3 . (canceled) 
     
     
         4 . The material system according to  claim 1 , wherein the medium includes two polymerization systems including a first polymerization system for accelerated solidification of an outermost layer of the medium over the plastic component, wherein two polymerization systems have different reaction times. 
     
     
         5 . The material system according to  claim 1 , wherein the medium includes a polymerizable material capable of accelerated solidification by means of the introduction of high-energy radiation. 
     
     
         6 . The material system according to  claim 5 , wherein the high-energy radiation is UV. 
     
     
         7 . (canceled) 
     
     
         8 . The material system according to  claim 1 , wherein the material system comprises an accelerator for hardening an outermost layer of the medium on the plastic material. 
     
     
         9 . (canceled) 
     
     
         10 . (canceled) 
     
     
         11 . (canceled) 
     
     
         12 . The material system according to  claim 1 , wherein the medium includes a monomer. 
     
     
         13 . The material system according to  claim 12 , wherein the medium encompasses at least one part, which is from the same substance class as a plastic part of the plastic component. 
     
     
         14 . The material system according to,  claim 1  wherein the material system comprises a catalyst and/or a wetting agent. 
     
     
         15 . The material system according to  claim 12 , wherein the material system includes a photo initiator. 
     
     
         16 . The material system according to  claim 15 , wherein the photo initiator is provided in the medium. 
     
     
         17 . The material system according to  claim 1 , wherein the plastic component and the medium encompass a methacrylate. 
     
     
         18 . (canceled) 
     
     
         19 . (canceled) 
     
     
         20 . The material system of  claim 1 , wherein the medium includes a methacrylate. 
     
     
         21 . The material system of  claim 2 , wherein the medium includes a methacrylate. 
     
     
         22 . The material system of  claim 8 , wherein the medium includes a methacrylate. 
     
     
         23 . The material system of  claim 12 , wherein the medium includes a methacrylate. 
     
     
         24 . The material system of  claim 16 , wherein the medium includes a methacrylate.
