3D printing pitfall?

Ice printing
https://techxplore.com/news/2022-08-3d- ... dical.html
Advances in 3D printing are making it possible to produce such tiny structures. But for those applications that require very small, smooth, internal channels in specific complex geometries, challenges remain. 3D printing of these geometries using traditional processes requires the use of support structures that are difficult to remove after printing. Printing these models using layer-based methods at a high resolution takes a long time and compromises geometric accuracy.

Researchers at Carnegie Mellon University have developed a high-speed, reproducible fabrication method that turns the 3D printing process "inside out." They developed an approach to 3D print ice structures that can be used to create sacrificial templates that later form the conduits and other open features inside fabricated parts.

3D printing--via cooking?
https://phys.org/news/2022-09-team-3d-p ... ctile.html
researchers at City University of Hong Kong (CityU) have recently discovered a low-cost, direct method to turn commonly used 3D printable polymers into lightweight, ultra-tough, biocompatible hybrid carbon microlattices, which can be in any shape or size, and are 100 times stronger than the original polymers. The research team believes that this innovative approach can be used to create sophisticated 3D parts

Microwave oven has interesting uses
https://techxplore.com/news/2022-09-mic ... ctors.html
The excessively doped materials enabled by microwave annealing would be key to the new architecture.

I wonder if anyone thought to combine these two approaches---experiments on 3D prints?

The other day, I dug out some 3D-printed HO scale beds I'd bought some time ago for another project. To my surprise, two of them had "ruptured"--blown themselves apart just as if they were subjected to some intolerable internal pressure. There was also a slight amount of black liquid, as though the beds had melted or been subjected to some solvent. I believe the beds were made using a UV-cured resin. Three other beds in the same package, but a different color, were a bit tacky, but a couple days under a UV bulb seems to be firming them up nicely.

It made me pretty darn nervous about using 3D-printed parts in something I want to last a long time, i.e, one of my models.

"What we are trying to investigate here is what is possible if we make three-dimensional structures smaller than the wavelength of light that we are trying to control."

A glance at these devices reveals something rather unexpected. Whereas most optical devices are smooth and highly polished like a lens or prism, the devices developed by Faraon's lab look organic and chaotic, more like the inside of a termite mound than something you would see in an optics lab.

The construct looks a bit like a Borg cube:
https://www.nature.com/articles/s41467- ... /figures/2

To turn these designs from a model on a computer into physical devices, the researchers made use of a type of 3D printing known as two-photon polymerization (TPP) lithography, which selectively hardens a liquid resin with a laser. It's not unlike some of the 3D printers used by hobbyists, except it hardens resin with greater precision, allowing structures with features smaller than a micron to be built.
