Hi, does anyone know about 3 D manufacturing and how to make a business out of its use for the novice. I have some money and would like to start some kind of business. Thanks for the answers.

I think you are referring to 3D printing as manufacturing is 3D.

Bear in mind that these printers are NOT cheap, starting at several THOUSAND dollars.
What where you thinking of printing ?

I've got several thousand. Seems to be this is the future in a lot of ways and I would like to get into it if there is a retail venue for it. I just retired and always wanted to own a business but never had an opportunity and a chunk of cash at the same time. Now I have the chunk and would like to find an opportunity and have them meld into a business that would make money and keep my mind busy. Thanks
