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

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.

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.

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.

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.

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.
