Excellent. It's always really just about what works.
I helped build a 3D printer from scratch, and reverse-engineered some Stratasys
stuff. There's always new materials, new techniques, and new tricks to push the
envelope with regard to what is possible.
Perhaps we should have a 3D printing sub-group....

Excellent choice, I head that Bambu's printers are stable in work and
produces high-quality models.

I like this idea, although it's not POV-related. Looking forward
for shots of your printed models. :)

I am going to print surfaces from this resource:
http://3d-meier.de/tut3/Seite0.html
using my MathView:
https://mathview.yesbird.online
like here, for example:

I've seen it used on machinist channels like Inheritance Machining,
and they were having a "sale", so I just ran with that.
Wasn't prepared to shell out for a high end machine, since I didn't
really know how much actual use it would get.
But it did set up fairly fast and produced some decent quality prints using the
default settings on my wobbly coffee table.

Then you're missing the point of the opening post.
People who are members of exclusive country clubs aren't there to play golf.
They're there to meet up with other people in the echelon and privately discuss
and arrange things that can't be done in board meetings, in offices on company
time, etc.
The 3D printing group is to attract people from outside the raytracing community
to the POV-Ray forums, so that they can be exposed to raytracing via a program
that uses a virtually identical language.
They may read other posts, and be able to offer helpful insights, suggestions,
or even code.
People can look through the 3D printing group and see something that they've
wanted to model and ask, "How did you do that?"
When we raytrace, an object in an empty POV-space will look flat, boring, and
substandard.
When we include objects in a scene such as HDR lighting or anything outside the
field of view that the central object can reflect or be influenced by via
radiosity, then there's a richness that can be achieved that is impossible to
get by rendering the central object alone. That was a lesson I learned trying
to implement iridescence - the bubbles needed something in the scene to
reflect/refract.
We cannot raytrace in a vacuum.
We cannot hyper-focus on "POV-Ray".
I only started making significant advances with what I do when I started
investigating ShaderToy, CAD/Cam, Unity, video games, mathematics, physics, c++,
and other topics in the large penumbra from which everything in POV-Ray
originates.
I am going to print surfaces from this resource:
http://3d-meier.de/tut3/Seite0.html
like here, for example:
https://www.ams.org/journals/notices/201208/rtx120801076p.pdf
Yeah - I have been periodically returning to my work on the Dupin Cyclide, and
so I'll probably try to make a wireframe Dupin Cyclide and maybe one with a
Steiner Chain of spheres inside.
- BE
P.S.
Also, he're's a direct crossover that is directly related to both 3D printing
and POV-Ray. :D

Because of the resemblance with POV-Ray I looked into it. The resemblance is
only on the surface. The ned to define all transforms before one can finally add
the actual object annoyed me, as did the strange immutable vars. But, as I
understood they started last year with adding a python layer that changes all
that. There is also a "patched" version of openScad that does that. Have not
tried it.
I looked into 3D printing and listed what I would do with it. The result, ah,
that I can make from wood. So, no printer, with the happy side effect of no
plastics.
The nice thing with woodworking is that I can do my visualisations in POV-Ray
and fully parametric. I can even print the parts list.
But yes, interaction with openSCAD and FeeCAD are good things to do. I still see
POV-Ray as two things, SDL and the render engine. I still think a SDL can be
created that serves multiple back ends, POV-Ray, OpenGL, and all the new fancy
ray tracers like Embree. But also CAD like applications and proper output to CAM
equipment.

It's also important to choose a good plastic according to your needs.
After a long quest, I am ended with this one:

Good luck with it, looking forward for images. :)

Well yes.
But it's really supposed to be my son's 3D printer. ;)

"Almost no layer lines"
I'm liking it already! Thanks for the suggestion.
Sometime soon I need to figure out printing with support vs bridging
(my "just print it" experiments have revealed that this bridges pretty well!)
using multiple filament colors, flipping parts that are oriented badly, scaling,
and then get down to modeling from scratch in something like OpenSCAD, since
it's been a good 10 years.
Also need to learn how to pause print to insert thing like threaded nuts, allen
wrenches, and other metal items.

lol.
I might have to start giving driving directions in <x, y, z> vectors.

Yes, it's true - I have checked, but maybe you should set some
parameters like layer thickness, extrusion, etc. according to
manufacturer's recommendations.

I know that feeling - a new device is a new world with huge space to
explore. Wish you a happy journey :).
Why OpenSCAD, but not so popular Blender ?

Familiarity?
Modeling something in OpenSCAD is just like writing a scene in SDL.
Also, it installs in seconds.
I think I tried to install and use Blender once, ages ago.
I can't recall how long the install took, or how much space it took up.
When I opened it, it was like trying to navigate through an alien spacecraft.
Maybe I'll give it another go.

Feeling the same, about translating/rotating something before it exists... also
I suspect its material system can't be made to match POV-Ray's
Also even though Python can do even better, POV has the merit to allow not to
call everything as functions as Openscad does, thus reducing the number of
parenthesis or braces to open and close everywhere. Overall, even though I kept
ranting about how more stressfull than Python it could be, looking at Openscad
made me value POV syntax more ! Thanks.
