Is this the return of brutalism :|

3D printed buildings do not have to lead a return to the ugly "concrete brutalist" architecture of the 1960s and 1970s. As Canadian architect Douglas Cardinal demonstrated - in his 1989 Canadian Museum of History - even simple applications of CAD/CAM can produce elegant curved walls that are pleasing to the eye. Cardinal used advanced software to draw simple 2.5 D walls that were curved in two dimensions. OTOH Cardinal's concrete and brick walls are essentially one dimensional vertically.
The beauty of 3D printing is that with only minor changes to software, you can easily 3D print 2D or even 3D walls that are curved both horizontally and vertically. For vertical taper, all you have to do is offset the second layer by a little bit: less than 1/4 the thickness of the wall.
Even Lennar/Icon/B.I.G.'s proposed 3D printed houses feature rounded outer corners which should reduce the amount of concrete per house by a ton or two. Those curved external corners eliminate concrete that carries no load, but WAS convenient to cast with flat forms. Moving away from flat plywood forms allows a greater variety of curves, both horizontally and vertically. Eventually compound curved roofs will be 3D printed with out labor-intensive temporary forms.

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.

New 3D printing process is faster and more precise than conventional methods

Rutgers engineers have created a way to 3D print large and complex parts at a fraction of the cost of current methods.

techxplore.com

The new approach, called Multiplexed Fused Filament Fabrication (MF3), uses a single gantry, the sliding structure on a 3D printer, to print individual or multiple parts simultaneously. By programming their prototype to move in efficient patterns, and by using a series of small nozzles - rather than a single large nozzle, as is common in conventional printing - to deposit molten material, the researchers were able to increase printing resolution and size as well as significantly decrease printing time.

"MF3 will change how thermo-plastic printing is done," said Cleeman, noting his team has applied for a U.S. patent for their technology.

Maybe an airframe can have water cooled skin used just once-on the ground-so that it might be surrounded by a TPS in one pour...the liquid used to prevent annealing during the heat-treat... and as a back-up during re-entry. Squirt aerogel between hull and TPS. Buran and Columbia weren't filled with cryogens like Starship-it might need tubes to keep TPS warm on ascent too. No cracking-so TPS can be one piece?
