I don't know nothing about this field, so excuse my ''stupid'' questions. Thirst of all what categories do we have when we say 3D-printing? I mean for home, for business and other stuff. What materials can I work with? Wood, wax, plastic, metal? What kind of metal? Cooper, iron, aluminum or steal? For example if I would like to print in metal I must have a business 3D-printing machine? Can someone with no knowledge of 3D-design, computer design or computer language still use it? Can I ''scan'' with with the printer the prototype of a glass of water for example and build my own? How much electricity (Watt or KiloWatt) need to work for 10 hours?
I would like to hear about your answers. If you think that I miss some useful information please tell me. I would like to give me some pages of selling 3D-printers and suggest some metal-print-able models. I would be glad to hear any answer. Thank you for your time.
Answer
Right now, the only 3D printing material is plastic, and maybe some metal that can be powdered. Those require some cintering, I believe, after it's been printed.
Is there a 3D scanner? yes. But you'll need to learn some 3D design software to manipulate the design after you scan it in.
Electricity? No idea. Depends on the specific 3D printer and the size.

What can I use to cast a mold from stone without hurting the stone?
disciple
I'm new to this, but does anyone know what medium I would use to make a mold from a stone. In other words, There is an old building with a beautiful design sculpted in to it. I want to copy this design. I know there is a material out there that I can press against the original design and make a mold of it and then cast the design in plaster. I just don't know what material I would use to do this without hurting the stone.... Help!!!
Answer
I think the sculpey or any clay will work. If you use normal clay, any residue left will dissolve in the next rain, just don't use brown clay on light stone... if you use water based clay you would have to cast your plaster into the mold while the clay is still wet.
As the clay won't be very stable just on its own, you should consider making a mother mold on top of that. That is a hard shell, which just gives support to the soft part of your mold so it doesn't deform. It depends on the size of what you want to copy if you need it. You could make the mothermold from plaster bandages, but don't put plaster directly on the stone.
Before you start, consider carefully the shape of what you want to copy and where undercuts are and where you have to put in parting lines. What technique you use for mold making really depends on the exact shape of what you want to copy. If the structure is something complicated, you may want to practice how to make molds from more simple structures first so you are aware what causes problems and get some experience in how to solve them.
Another completely contact free method is if you happen to be at a university where they have a 3D laser scanning camera you can borrow, you could use the 3D laser scanner then make a model of your structure in the computer from the scans. That you could print out using a 3D printer. that way you can scale the model to any size (though anything large will be expensive to print)
