Considering the Environmental Impact of 3D Printing


Manufacturing with 3D printing is now a fast-growing field, with the technology becoming more accessible and affordable. Some think that it will revolutionize all kinds of manufacturing. But, while it offers some advantages, the process can be energy intensive and wasteful of material. A recent study has a comparison of some 3D printing and conventional milling methods.

There are many different kinds of 3D printing, and this study is buy tramadol saturday delivery only an early examination of a few methods. The environmental impacts between different printers (different printing methods) were not as great as the those between occasionally operated printers and ones in more consistent production (which is more efficient). "In cases like this, job shops legitimately can argue that they provide both economic and environmental advantage to their customers."

Equally importantly, the kind of object being produced can make a huge difference in the amount material used. An object with a great deal of no prescription cheap viagra hollow space will be easier to produce by 3D printing rather than milling. In some instances, "an inkjet 3D printer (which lays down polymeric ink and UV-cures it layer by layer) wastes 40 to 45 percent of its ink, not even counting support material, and it can't be recycled."

Regardless of method, 3D printing is not going to replace other methods of mass production, any more than laser printing replaced all conventional printing. "3D printing is not going to replace injection-molding for mass-manufactured products (plastic parts made in the millions). It is replacing machining for smaller runs (1 unit, 10 units, maybe 1,000 units)." Each has its advantages, for its appropriate application.

What about the transport impacts?
written by Kit England, July 26, 2013
comments on the link focus on concerns of giving environmental printing to everyone and only today cialis without prescription online rising resource use, but I don't think this will be too much of a problem - economics will constrain people's printing habits. What's much more relevant to consider is the http://www.umlauf.de/female-viagra-pills impacts on the transport of materials etc - It's too early to cialis website say but presumably the transprot of best viagra buy Ink to population centres is cheaper than manufacturing, and shipping/road transport to shops etc...

Although it may be good for the environment, it may not be very good to human health as it apparently emits very fine nanoparticles which can easily be ingested into the lungs. (Source: http://phys.org/news/2013-07-3...ially.html)

I think the 3-D printing is an environmental win as it saves a good deal of shipping and thus gas and other fuel. People will be able to download and print items rather than use natural resources to have them delivered to them.

3D printing is the future
written by Tomas J, August 02, 2013
3D printing is still very new, and will over time get better at not emitting small particles or other pollutants. Weigh in the transport factor, and you have a printer that for sure will revolutionize our several industries.

Plastic recycle
written by Dylan, October 03, 2013
What about the plastic recycle and how they reproduce the plastic doesn't that produce any problems with the problems. melting the plastic and reforming it is a problem. Also you need to www.toscanalifesciences.info buy more plastic resources so how are they going to end up in the buyers hand?
