Will 3D Printing Transform The World -- Or Just Fill It With Non-Biodegradable Personalized Junk?
from the what-a-load-of-rubbish dept
It's clear that 3D printing has moved well beyond the breathless novelty stage, and is entering the breathless hype phase, with everyone declaring that it's the next big thing, and that it will transform the world etc. etc. etc. There's no denying it's a powerful technology with great possibilities. But against a background of uncritical boosterism, it's good to come across an article in the Architectural Review that points out some of the problems we will need to address to realize its full potential. Here's one:
We could start by properly critiquing the impacts of this technology beginning with a much deeper analysis of the materials used, the energy and resource requirements, and the supply chains that result in printed objects. Fully characterising the current production systems may help us to understand how they could be developed into ecosystems of exchange where the coveted objects can be meaningfully recycled by our biosphere.
It's all very well being able to print objects on demand, but unless the ecological implications -- both in terms of the raw materials used and the energy required -- are considered, it may well be that 3D printing is actually a step backwards when it comes to environmental impact. The ability to re-cycle 3D-printed objects needs to be built in from the start.
Another problem is more subtle:
If 3-D printing does not fully take on this responsibility then the sustainability of our current highly 'customised' objects is likely to be under scrutiny, as the unit cost of printers falls and hobbyists make legions of white elephants out of toxic plastics and when our landfills are chock-a-block with yesterday's badly made fashionable shapes. And while some -- such as ultrasound embryo portraits -- may have enduring sentimental value, it is likely that most will simply clutter up our rubbish dumps and precipitate our plastic marine continents as indestructible rubbish icebergs.
As this points out, if we are not careful, the personal manufacturing revolution may become the 3D equivalent of Geocities: a huge flood of badly-designed, useless pieces of junk that are soon abandoned by their embarrassed creators.

Thank you for reading this Techdirt post. With so many things competing for everyone’s attention these days, we really appreciate you giving us your time. We work hard every day to put quality content out there for our community.
Techdirt is one of the few remaining truly independent media outlets. We do not have a giant corporation behind us, and we rely heavily on our community to support us, in an age when advertisers are increasingly uninterested in sponsoring small, independent sites — especially a site like ours that is unwilling to pull punches in its reporting and analysis.
While other websites have resorted to paywalls, registration requirements, and increasingly annoying/intrusive advertising, we have always kept Techdirt open and available to anyone. But in order to continue doing so, we need your support. We offer a variety of ways for our readers to support us, from direct donations to special subscriptions and cool merchandise — and every little bit helps. Thank you.

Yes.

Re:
i will say this in reply to some of the misguided remarks of posters below: architects *rarely* get an opportunity to design/build buildings which are a edifices to THEIR OWN 'egos', etc... in general, they are at the mercy and whim of THE OWNER'S ego...

Also, I'd gladly go back to the GeoCities days versus the Facebook days. At least those "badly designed" pages were more creative and individualized than this current social media generation.

Re:
Yes, it's just too bad that you could view more than a couple pages on any given site before it hit its ridiculously low bandwidth limit and became unavailable for hours.

But there is another point, is not just plastic, everyone needs to find a cycle for themeselves.
An example would be water today everyone open their faucet the water comes in and then goes out, nobody knows how that water got there, how it was processed and they don't care where it goes, if you do that with plastic it will be a problem, but there is another way you close the cycle, instead of using thousands of litres or gallons a month one could be using just a few litres to replenish what was lost do to leaks and evaporation, think about a shower that uses only 5 litres of water to function, it throws clean water over your head, collecting it, filtering and pumping it back, sci-fi? no it already exists.

Now, thre are the other sources of water to be closed like the kitchen and toilet.
The same with plastics, there are some plastics that can be easily recycled all of them can be but some need to be dissolved into their monomers first so as to recreate the bonds that broke down over time, find that and find the uses and I am sure a closed system for plastics can too be created.
I was just reading about artificial muscles created from normal everyday fishing lines that can are roughly double the strength of natural muscles, that is a good target it can create clothes that would self adjust, opening vents that react to ambient temperature, etc, now imagine you could manufacture those at home?

I see homes becoming more like our own bodies, we don't throw out things we reuse everything to the molecular levels and only put out what we can't process and is in excess.

Re: 02170
One more thought. How much more efficient is rapid prototyping using a 3D printer, be it by powder or extrusion, than full scale mockups. Hell, just think of the energy, materials and lubricant needed to CNC a shape from a billet!
Innovation costs, folks. Lack of innovation costs more. For myself, I prefer food raised the new fashion way (I will have extra pesticides and fungicides with that salad, please), a bit more dolphin in my tuna, sweet crude imported from the middle east or other far away place for my modest car, hydro or nuclear power, chlorinated water and medications produced by big pharma.

What about the ability to make on-demand replacement parts so that an entire item doesn't have to be replaced when one small component breaks? I thought that green activity was supposed to be one of the principal attractions of 3D printers.

PLA
[ link to this | view in chronology ]
Re: PLA
As one of the two most common plastics used in 3d printing, PLA is
1. Renewable (can be made from corn and milk by products),
2. Non toxic (and in some cases food safe),
3. Recyclable (can be ground up and used as input to new PLA production.
4. Biodegradable
5. Compostable
tldr; OP is full of shit

Re: Re: PLA
The people I talk to don't tend to consider it food-safe, btw, due to the FDM process not making very flat surfaces (which makes it hard to clean, and pla doesn't take to really hot water all that well).

Re:
What is this "raw material" stuff you speak of? Everyone knows that you just plug a 3D printer into your computer and it magically spews out an infinite steam of objects created from thin air!

They are working on the shredder to turn the plastic item into the small pieces needed for the filament maker.

YES Biodegradable!
Here are a couple useful Wikipedia articles to get folks started on the subject:
https://en.wikipedia.org/wiki/Biodegradable_plastic
https://en.wikipedia.org/wiki/Bioplastic
A nd please folks, understand that turning such plastics into mulch and compost does NOT mean they are returned to the environment as CO2. They are mainly decomposed into dirt, which is one of the basic requirements for most plant growth.

Re: 3D printer green sustainability
In any case it doesn't matter if people don't take the environment into account. It will come back with the bill sooner or later. Either that or God is fooling around with the weather tab of His SimUniverse game...
