What the adjective "downstream" is used for? I'm working with a project involving 3D printing's terminology, but I'm not such an expert... so I was asking myself if someone can explain the meaning of the "downstream" adjective in this field. 

More precisely, I'm dealing with this sentence: "Handle any downstream task", which I really can't understand because it has a very poor context. 

I also have this sentence with the adjective that I'm having trouble with:


  Confidently send your surfaces downstream knowing your results are usable design surfaces.
Without more anymore context "downstream" could be in reference to a print that would be sent to another machine for post-processing. The post-processing machine is "downstream" from the machine used to make the print in the first place.
