People should not confused 3D printers with star trek replicator that work by rearranging subatomic particles, which are abundant everywhere in the universe, to form molecules and arrange those molecules to form the object.That is beyond today's technology.

Way too many subatomic particles to move around and for computer to keep track of them all.May be if we had quantum computers they would be powerful enough? But today's computers are too crude.
Anyone confused about that should look at all the amazing things we can do with nothing like that level of technology, as mentioned above. Take the organ printing for example. You are working at a comparatively crude level and letting the cells do all the really complex stuff of connecting to their neighbors. Maybe one day we will be printing titanium boned, dinosaur shaped chickens with technology like that.. but what do startrek script writers use those molecule-accurate replicators for? a cup of tea.

You DO realize how damn difficult it is to make a decent cup of tea right?

I read we are about 50 to 100 years out from having a replicator like in star trek if computing power does not slow down.Main problem is computers are too crude today for it.

I read they have done experiments in lab moving molecules around.Not atoms yet.

In regards to using 3D printer for creating spares for Space station.
Currently there may only be a few percent of spares needed that can be printed because ISS was never designed for spares to be printed in space. Future space stations will be designed to make the maximum use of 3D printers for spares manufacturing. This may involve rationalising materials so bulk of components are made from printable materials.

It sorta depends upon how you want to count. Made In Space claims that there are a large number of parts used inside the station like clamps for wires, braces, things like that, that can be made by their printer. So we're not talking about large structural items or things that don't break, but stuff that's used in day to day work.

In the email.  Confirmed 16,000 lbf 3D printed SupetDraco engine. Check out the throttling and pulse rate.

Quote
Each SuperDraco produces 16,000 pounds of thrust and can be restarted multiple times if necessary.  In addition, the engines have the ability to deep throttle, providing astronauts with precise control and enormous power.

The SuperDraco engine chamber is manufactured using state-of-the-art direct metal laser sintering (DMLS), otherwise known as 3D printing.  The chamber is regeneratively cooled and printed in Inconel, a high-performance superalloy that offers both high strength and toughness for increased reliability.

“Through 3D printing, robust and high-performing engine parts can be created at a fraction of the cost and time of traditional manufacturing methods,” said Elon Musk, Chief Designer and CEO.  “SpaceX is pushing the boundaries of what additive manufacturing can do in the 21st century, ultimately making our vehicles more efficient, reliable and robust than ever before.

Something on topic, http://sites.nationalacademies.org/DEPS/ASEB/DEPS_084763
Space-Based Additive Manufacturing of Space Hardware
Quote
The National Research Council will appoint an ad hoc committee to explore the implications of space-based additive manufacturing technologies for space operations and the manufacture of space hardware. In conducting the study and preparing its report the committee will:

    Assess the current state of additive manufacturing in the United States and worldwide (especially in the aerospace industries, universities, and national laboratories engaged in the design and manufacture of small satellites or respective subassemblies);
    Characterize the future states envisioned by the aerospace industries, universities, and national laboratories with respect to additive manufacturing and aerospace systems;
    Discuss the feasibility of the concept of space-based additive manufacturing of space hardware (including, but not limited to, a fully functional small spacecraft) that can conduct or enable missions of relevance to NASA, the Air Force, and/or the national security space communities;
     
    Identify the science and technology gaps between current additive manufacturing capabilities and the capabilities required to enable a space-based additive manufacturing
    concept, including those gaps that current trends indicate may be closed with commercial investments in additive manufacturing and those gaps that are likely to require
    dedicated investments by the federal government.
     
    Assess the implications that a space-based additive manufacturing capability would have on launch requirements (e.g., launching raw materials versus fully assembled
    spacecraft); overall satellite and payload designs; and in-space operations, such as possible reductions in mass and their implications for activities such as
    maneuverability.

It's an EOS DMLS (Direct Metal Laser Sintering) machine. From Musk on Twitter:

Maybe, maybe not. At the Dragon V2 Q&A Helodriver recorded Musk as saying they use EOS, SLM and Concept metal printers. Concept Laser's printer is huge with a print volume of ~125 liters, enough to print a V-6 engine block.

I'd bet as soon as Musk gets one large enough to print a booster engine chamber he'll try it, if for no other reason than to explore the possibilities.

Lockheed are also embracing 3D printing.

you forgot that fantantisish video
(YouTube video snipped: ?v=perMGY0oajs)
Very epic vid! Really shows how big they are compared to companies such as SpaceX.

Another development

http://www.parabolicarc.com/2014/05/31/pisces/

Quote
The second PISCES-NASA project involves 3D printing on a construction scale using basalt. Here on Earth, 3-D printers are already building houses using recycled materials. In space, however, blasting construction materials via a rocket is too costly. Basalt could be the key to building infrastructure in space using robots. Because Hawaii’s basalt is so similar to the regolith found on Mars and the Moon, it could be used to 3D print shelters, landing pads, and tools ‘in-situ’ – or on-site- on other planets
