Artificial organs ???
Artificial organs ???
(OP)
I have seen a kidney preparation where they filled the
blood and urine vessels with plastics of different color
and dissolved the tissues.
Could'nt similar methodes be used to make artificial
lung,kidney, etc.?

gold, titanium alloys, PEEK polymers, carbon fiber, tantalum, most silicone
The problem with creating a functional organ is that they are very very commplex things that are constantly involved in active chemical processes. I don't know what fabrication method we currently have that would match the macroscopic scale of a full lung to the microscopic pore size needed to actually trade oxygen molecules into red blood cells. I think a blood cell is something like 0.00004in wide.

I am suggenting a way to try to use the organ as a king of
sacrificial template

RE: Artificial organs ???
then use the mold as a sacrificial core to make a replacement organ, then dissolve the core.
There are a few questions to be answered before you go into production...
- Where do you get the sacrificial organs?
- Do they need to be healthy?
- Can the listed biocompatible materials be fabricated by the replication process you have suggested?
- Is the resulting physical replica of an organ's topology sufficient to serve as an organ replacement?
( I don't think so, because ... )
- Given that the replica is made of bio-inert materials, how can it participate in the molecular chemistry that is at the core of most organs' function?

Not trying to be exclusively negative, but casting a mold of an apple does not make the result a fruit.

Waiting for the 5th Element machine to spit out a supermodel....

- Where do you get the sacrificial organs?
pigs or cadavers ?
- Do they need to be healthy?
most likely
- Can the listed biocompatible materials be fabricated by the replication process you have suggested?
The listed ones or new ones perhaps using stem-cells.
- Is the resulting physical replica of an organ's topology sufficient to serve as an organ replacement?
The dialysis filter is only partially functional
but still useful.
