3D Printing is a Scam

Yay yay yahoo - so-called '3D printing' is supposed to be the 'next, biggest, bestest thing since sliced pizza' but I'm not buying it. I think it's a scam.

And I'm not talking out of inexperience here, either. I've already figured out how everything else in the world is a scam - 'shipping and handling,' 'climate warming,' 'true love,' most religions, panda bears, gluten-free bread, 'three plies,' 'non-stick surface,' 'best-selling.' Indeed I would say - "There's a scam for that.'

So in conclusion, I don't know yet what the scam behind 3D printing is. But I know there is one. Stay away from 3D printing - it's a scam I tell you!

I'll agree, to an extent.

3d printing isn't, in many cases, any better than CNC machining (which has been around since the 1950's).

CNC machining can give a better finished product, since you can make things out of high carbon steel instead of powdered metals (or plastic).

The skills required for programming CNC and modeling for 3d printing are about the same, and the cost isn't terribly different between 3 axis CNC and 3d printing, while CNC is about a hundred times faster.

What is the difference to the customer between carving something out, and building something up?

Hollow 3d printed steel components for cars would be cool, but ultimately you'll have to machine some of the surfaces.

I admit, you can make cool plastic balls with smaller balls inside them, which can't easily be done with CNC, but really, what is the big deal?

To me, it feels like evolution, not revolution.

You have no idea what is possible

We are only at the very beginning. You aint seen nothing yet...

The most powerful Law of Nature is Time. It is finite and we all will run out of it. Use this Law to your advantage, for it offers you infinite possibilities...

You mean like 3d printed security cameras?

???

Don't feed the pandas. Ever.

Imagine printing an assembled engine?

or maybe even an assembled vehicle.

We are only at the very beginning. Imagine all of injection molding being replaced with 3D printing or all machined metal and plastic components printed.

I don't think you realize where this is all going.

There are many more ways to print things than are currently commercially available. There are ways to print just about anything that can be made its just going to take a while to fully master this capability. The full expanded capability will require a new energy paradigm. Once that happens man will see the day of POOF there it is of nearly anything. We already know it possible and that the building blocks are already being done in various ways.

Posting

Posting just for the sake of posting is a scam
If you don't like something, keep it to yourself
We should try to be positive in our outlooks, not negative.

Yeah. And also it is a big

Yeah.
And also it is a big joke that this is under 'DP Original', lol.
