This paper discusses the behavior of providing and disseminating CAD documents of patent products in 3D printing, which helps or entices others to download the documents and print the patent products accordingly. It is an indirect infringement of patent, and puts forward suggestions and measures to prevent indirect infringement of 3D printing patent.
