Uh, the widely varying properties, maybe? Titanium and gold have
slightly different properties.

Jimp posted a reference to a Wikipedia article. You really should
read it.
We can 3-D print *right now*:


Thermoplastics, eutectic metals, edible materials, Rubbers, Modeling
clay, Plasticine, Metal clay (including Precious Metal Clay), Ceramic
materials, Metal alloy, cermet, metal matrix composite, ceramic matrix
composite
Nylon or Nylon with short carbon fiber + reinforcement in the form
Carbon, Kevlar, Glass and Glass for high temperature fiber
Photopolymer,Photopolymer + thermally activated chemistry
Almost any metal alloy including Titanium alloys



why not print pizza.... ? should be a huge demand for that...

I saw a pancake printer at Makerfest a few years ago. The pancakes were
pretty good tasting too.

Why would you print, rather than extrude?


Some people are monomaniacal about 3D printing.


I guess the difference is the size of the dot. Pancakes are just a
big dot.


Pizza is a big dot, with smaller dots on it. embedded dots.

I believe this has already been done.

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

atm-opens-xavier-university-cincinnati-n626501

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

Not the point, remember the whole "mature technology" thing?

time.


Yes, it is the whole point.

They get speed by using thick layers as there is no other way to do it.
This
results in a crap finish.

And this IS an industrial grade printer.



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:

On the other hand see this:

Navy Partnership Goes to New Depths with First 3D-Printed Submarine.
JULY 20, 2017
https://energy.gov/eere/articles/nav...nted-submarine

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.
