Both products in the links don't exist yet.

If they do successfully finish them, they won't make any money. I bet they lose money on them.  They are 800 dollar products that they are selling for 200 dollars and I bet they will suck.  No examples of their output.

A nice way of putting it Duane!  Sometimes you have to go back and look at what you have already done at some point later to see if you can do it better.  For one, you should now have your lessons learned on what you liked and what you think that you can do better.

I am sad to see that you have not taken up the challenge.  I really am.  Good healthy debate is ok, it helps everyone from time to time to reevaluate positions.  Unfortunately good debaterequires effort and not just three sentence zingers.

 

The first link there from Engadget actually encapsulates a lot with what we are trying to do with this project.  We are looking to go smaller than is traditional.  This allows us to reduce the size of the components as well as power requirements.  This in turn reduces cost.  I would invite you to read that story as it even serves as a good look at concepts such as engineering trades.

re: "If it can be done then someone else probably already did it, so buy their solution."

I kind of think that much of what engineers do is reinvent the wheel. In fact, I don't think technology can really advance if we don't spend a lot of time reinventing the wheel. I like my kelvar belted radial tires with grippy all-season tread.

Ok, so you have shown that there are a small percentage of products that fail, but then I could counter your point with the fact that there are a larger percentage of products that succeed.  So the point you have made is negated.  Just to start, I will list a few that have become successes: Red Pitaya, Peble Smart Watch, Arduino Screwblock Proto Shield, Hexairbot, Oculus Rift, etc.  These are just the ones that I can name off the top of my head without doing any web searches.

 

Though back to the point of debate, please show me on 3D printers that I listed will cost $1000 to make but the vendor will sell them for $300.  This is an important part of debate and learning.  Substantiating your point.  I have no problem having a difference of opinion, but in order to convince me of your point, you will need to do so with specific, applicable analysis and substantiation.  I would estimate that to do this properly that it would actually be around 400-800 words.  The gauntlet is laid down my friend, I hope you accept the challenge and help us learn by a more thorough analysis.

I would be interested in hearing where you are getting your numbers are from as far as costs.  What are your assumptions? Volume? Profit margin?  I cannot think of any small companies that would be able to have ~$3.5 million in orders and be able to essentially suffer a ~$17 million loss.  In order to do so, this group would have needed to have some pretty heavy VC investing as well as a business plan that somehow locks in users long term to recoup that investment.  So far, I see the exact opposite.  This group is pursuing a high volume, low profit margin plan.  There is no Amazon Kindle effect here.

 

Once again, I am not trying to be rude, but at the same time, your claims are not passing the initial smell test do to lack of supporting details in your analysis.  There is a lot to learn from people, and perhaps you have certain experiences that can be shared.  So far though, you have manifest unsupported claims without any real substantiation.

Those are not real products yet from companies that will not survive, or end in failure.

I can design a 3d printer that will cost me 1000 dollars then sell it for 200 dollars too.  Better yet, I should start a kickstarter campaign then take the money and live in Mexico.
