Everything is a bit 80s today, haven't you noticed?
Jurassic and Terminator was just released, they are making new Top Gun. ;)

no wonder your prints are not lasting, you are using PLA :)
Also, even ABS is best printed with strong cooling at around 280C+
Very strong layer bonding, less warping. Those parts last better too.

some cool things you've been making :) especially that racing steering wheel for pc :)

I have made practical, durable, every day objects.
From small things like keychains to maxing out the envelope of a usual 3d printer. Hell, i even have 3d printed parts under the hood of my race car :D Yes, i actually race it, and have used those parts for a year now and they are holding up just fine and the car is rather quick actually, thanks for asking.

and they are researching into making 3d printing CHEAPER than injection molding, and they are already getting pretty darn close!

lol. Quite to the contrary.
True - ABS has limited heat cycles, and lowish glass transition temperature, but it's not immediately liquid @ 105C.

I've been using velocity stacks made from ABS on a race car for almost a year now - no issues what-so-ever, even tho it's the cheapest kind of ABS and isn't chemical resistant. They work brilliantly.

Nylon parts i've been using as well, harder to print due to the prep tho, but from Nylon which has even lower glass transition temperature car manufacturers make intake manifolds these days - even for turbocharged. Glass transition of 85C.

You are assuming that bitcoin mining will exponentially keep increasing and no new efficiencies discovered. Wrong.
Bitcoin mining is auto balancing by the value of each bitcoin. If energy spent costs more than bitcoin acquired, people will not invest in new mining hardware. How could they, or is money somehow infinite for the miners, to be able to purchase more and more gear?

FIAT money is not energy free neither.
Bitcoin is revolutionizing how money is conceived, FIAT money is basicly a huge scam, there actually are parties in this world for who money *is* infinite, such as goverments and world bank. See documentary Zeitgeist.

Bitcoin takes the power from the elite to just print more money away, and that's a bad thing?!?!

sooo... You are predicting that bitcoin will disappear in August 2016?

as long as there is bitcoin, there is miners. The reward simply halves and halves, and eventually it's the transaction fees which will cover the expense of mining. At this point 1BTC is probably 50k +

Skipping steps becomes a real issue when you start driving it faster and faster ...
and print time is a serious issue with current gen 3d printers... make it faster, without loosing precision or causing missed steps, at the same cost makes tons of sense.

It's not a matter if there is stronger and more precise machinery available - it's a matter of getting it to consumers, ie. on the cheap.
Getting price down on things is just as much a science as everything else - but it's different, and mostly engineering rather than science in instances like this.
It's about figuring out how to utilize something existing, now cheap, on creating new things.

Money is not infinite for everyone but goverments and big banks.

As with all scientific theories - they are made to be rebutted, more accepted, the better!
From his point of view it's probably very logical to take steady-state model over Big Bang Theory - so maybe he just has a deeper understanding of the subject and he's a genius .... or more likely HIS view is just that way biased, he sees Big Bang as impossible
He might be the next Einstein.... or not

IMO, our view of the universe is way too small to say either as definite, right now it looks like big bang is more plausible. Then again the energy levels involved in big bang are so insanely out there it's impossible to imagine... Infact the energy levels required are infinite to the infity, if universe is defined as infinite. Universe needs to have absolute limits in size for big bang not to return value NaN.

Until we can expand our view of the universe by .... let's say going out there at least few thousand light years away from earth, to at least 3 different directions, it's pretty much complete guesswork...

Yet, by research we started taking measurements at the coldest point in recent history of recent few hundred thousand years.
Hence, the CLIMATE CHANGE, is most likely just natural change.

This research was done by drilling into ice taking a core sample. Ice has "memory" in regards of temperatures from history, of course those are just annual average readings, but that's what GLOBAL WARMING is supposed to be as well.

If you want to see ecological damage, take a look at ground water pumping and other sweet water sources, cutting down forests. Now those are scary things!

Global warming is mostly sensationalist journalism.
Climate change on the other hand is real, and somewhat tangible. The source of which is probably nothing man made.

Nature of this little blue ball is much much more resilient than people think.

More we burn fossil fuels:
* The more vegetation will grow due to increased CO2
* Plants will clean the air, while taking in sunshine, increase the net energy content of this little blue planet, by storing it into biomass. (increase in total net energy content is a plus, we can use that biomass to make biofuels)
* More of the heat generated by using any form of energy source which has been stored (ie. fossil fuels, burning wood etc.) is radiated out of this planet
* Less heat is extracted out of the core, because the heat difference is closing
* Ice caps work as short term buffers, while they melt they release chemicals, some of which can contribute into cooling the planet.
* If temps are higher, it means more water evaporates == more of the heat is utilized on evaporation process causing cooler temperatures
* More cloudy it is, the sunshine doesn't get to surface, and is reflected backwards (clouds are rather white after all... hence reflects IR radiation) out of the planet

If any effect what-so-ever, climate change is affected much much more by eating meat than anything else.
Don't eat meat, and you could have 2x Hummer H2s humming 24/7/365, and tons of other wastefull stuff and you still contribute less to greenhouse gas emissions than average joe. Seriously, it's that much!

Much more alarming is the amount of forests being cut down, and sweet water usage levels etc. than anything relating to greenhouse gasses, global warming, climate change or whatever you want to name it.

In my opinion, the whole climate change/global warming is a huge elaborate conspiracy scam to make people pay more for their used energy, in whatever form, created by the huge hidden powers behind the mega corporations of the world, things like OPEC which is a legalized cartel working 24/7 on ways to increase fuel prices.

Oh btw, we have no such thing as shortage on fossil fuels, that's another load of crap. Today we have the means and technology to do full compatible biofuels at likely cheaper rates than barrel of oil is going for.... Tho, mysteriously those companies tend to disappear shortly after coming public with their advancements.
Current ethanol trend is just another scam to put more money on the pockets of farmers as well, very very inefficient. much more efficient methods exist than farming sugar corn etc. for making ethanol. Any biomass can be turned into ethanol rather cheaply in mass production, provided you have the right scientists working for you, thanks to bacteria and genetic engineering. Same method can be used to make any hydrocarbons on the cheap as well...

Why do these exist in? Because people in power benefit from these "problems", they work as a wonderful revenue source AND very nice distraction from actually important stuff... you know, like advancing human race as a whole and therefore endangering the position of the powers that be.

Someone would have said all the same things about electricity at home, phone, internet, cars etc.

1) Make it happen
2) Make it happen reliably and repeatably
3) Make it happen at decent speed and quality
4) Then you make it cheaper

and when you get to the point 4, things tend to start getting better quality and faster for less as well as more people adopts the tech and makes it better.

not just a toy.

it allowed us to create products affordably we couldn't otherwise make, in production, for sale. We are a typical small business with constrained budgets for creating products and small customer base.
It affords us to create products where the production costs are rather low, thus a comfortable margin product to make the product viable in the first place, with big commercial competitors, albeit the big commercial competitors have inferior products, with way higher price tag.

Further, 3d printing allowed us to rapidly prototype our product, turnaround for a new prototype can be less than one day, and we've done that many times over, and in early design stages multiple prototypes a day. Hiring a shop to machine parts for us the lead time for new prototype would be couple of weeks, and the expense would be orders of magnitude more.
