Towards the *fully* 3D-printed electric cars.

Let's do a quality control check.

"Conveyer Plate"? It's a "pizza peel"!

The crust isn't even tossed...

I believe this has already been done.

While not a printed pizza, the first "pizza ATM" was installed in my state:

If these things can be profitable anywhere, it's on college campuses.

A National Institute of Standards and Technology (NIST) noted this is a problem with 3D-printing, that there is wide variation in results and quality even in 3D-prints of objects by the same process:

NIST ADDRESSES METAL 3D PRINTER CHALLENGES WITH DIGITAL THREAD STRATEGY. BEAU JACKSON 2017-07-17 8:17 PM [quote] In collaboration with Duck Bong Kim at Tennessee Technological University (TTU), the National Institute of Standards and Technology (NIST) has published a study addressing three of the challenges to production-ready metal 3D printing. The proposed model could eventually form a standard for 3D printed metal parts and aid additive manufacturing through the certification process ? often seen as a primary barrier to progress.[/quote]

They propose solutions based on a uniformity of the digital information provided both before and after processing.

21st-century technology, from the space elevator, to private, orbital launchers, to 'flying cars'. This crowdfunding campaign is to prove it:

Nanotech: from air to space.

On the other hand see this:

Navy Partnership Goes to New Depths with First 3D-Printed Submarine. JULY 20, 2017

It's a 3D-printing of a carbon-fiber submarine hull. Judging by the video the finish is quite smooth in this case, which would be required for a submarine.

Exactly what a 3D printer is usefull for, a one off prototype.

Now that is cool! I'd be tempted to buy one for my granddaughter.

Now if it could only make aluminum pancakes, we could save the world.

An article from 2015:

Just saw this:

SPEE3D Puts Supersonic Speed in Metal 3D Printing. Michael Molitch-Hou posted on July 26, 2017

According to the company their method which uses high speed (supersonic) jets to deposit the metal does not have the resolution of other metals so they are focusing on applications where that is not required.

Carbon nanotubes can revolutionize 21st-century technology IF they can be  
made arbitrarily long while maintaining their strength. 

Some proposals to accomplish that here: 

From Nanoscale to Macroscale: Applications of Nanotechnology to Production  
of Bulk Ultra-Strong Materials. 
American Journal of Nanomaterials. 
Vol. 4, No. 2, 2016, pp 39-43. doi: 10.12691/ajn-4-2-2 | Research Article.

Which means pretty much every part in a car couldn't be printed with this.

An article from 2015:

And this is fast 3D printing in plastic on a conveyor belt:

3D Printing Big/Long Objects.

Could it be adapted to print metals?

An other subjective quote from the same article:

" But for the first time, a handful of 2016 models sold in neighborhood car dealerships will feature ultralight yet expensive carbon fiber materials. "

A large part of the racing bikes sold in the Netherlands are carbon fiber.

So?
