3D Printers

A plastic frame for under support would be quite thick but would easily enhanced to create a great sealing for the interior once the concrete was dry. Of course the concrete would be thin layered to get the first hard shell in place then one could work the inside plastic surface with laser or other sources of heat to make the seams between layers bond tightly together.
At that point any shape would be possible from this method of construction.

For SpaceNut re #276

I missed a beat there .... I was trying to suggest that with the right materials, you don't need a support underneath to make most of walls of a dome. Your post #276 is talking about a plastic frame. I had just offered you an historical example of building a dome in Italy without a wooden scaffolding.

It should be possible to take advantage of modern technology, modern mathematics, and the technique that worked in Italy hundreds of years ago, to build domes on Mars without scaffolding.

Another example of building a dome without scaffolding is the technique used by Eskimos (in the past if not currently).

In the age of ** real ** igloo construction, blocks of snow were shaped to form the walls of a structure so that the ceiling came together at the top, leaving a small hole for smoke to escape from an oil fire.

3D printing could be done is the modern age to achieve the same effect.

3D Printing Could Soon Weld Plane and Car Parts Out of Metal

Imagine hitting Ctrl + P and out comes a car part.
That's the dream behind an innovative new 3D printing technology, which Massachusetts firm Seurat raised $21 million to develop on Wednesday with the support of a group of the world's most powerful manufacturers.
Heavy Metal Gutenberg
Okay, it's not actually as simple as hitting Ctrl + P, but what Seurat is working on could produce a major breakthrough in global manufacturing. While it's been around since the 1980s, 3D printing is mostly used to make plastic parts and prototypes. That made the tech useful at the onset of the pandemic when some places used the technology to make medical protective equipment, but the things that can be produced are still relatively small in scale and sometimes time consuming. The worldwide market for 3D printing products and services remains relatively small, at just $12.6 billion in 2020 according to data firm Statista.
The 3D printing frontier with breakthrough potential is metal, but companies have struggled to develop ways to make large car or plane parts, or metals for electronics, for less money and in less time than current manufacturing methods. Seurat thinks it has found a way:
The company has developed a high-powered laser beam that can be split into up to 2.3 million beams of light, which can be programmed to weld around high-resolution images.
Every beam, or "pixel," can pinpoint its own spot, allowing Seurat's system to weld large areas of metal powder instantly, which could allow companies to manufacture metal parts domestically and more quickly than through current supply chains — it can already produce multilayered objects 10 times faster than current 3D printing technology.
Will It Scale? Seurat has raised $75 million to develop its technology so far, but doesn't expect to begin even trying to commercialize it until later this year. On Wednesday the company said it has already secured letters of intent from seven of the world's biggest automotive, aerospace, energy, consumer electronics, and industrial companies to join its commercial program. Its impressive list of investors — which includes Xerox, GM, Porsche, and Siemens — may give a hint as to who those companies are.

Here is more detail on the new multii-point laser 3D Printer metal printed method...

https://www.yahoo.com/news/3d-printings … 01236.html

A new metal 3D printing technology could revolutionize the way large industrial products like planes and cars are made, reducing the cost and carbon footprint of mass manufacturing.
Why it matters: 3D printing — also called additive manufacturing — has been used since the 1980s to make small plastic parts and prototypes. Metal printing is newer, and the challenge has been figuring out how to make things like large car parts faster and cheaper than traditional methods.
Get market news worthy of your time with Axios Markets. Subscribe for free.
A new method from a startup called Seurat Technologies — using a powerful laser technique — could be the breakthrough the industry has been waiting for.
If Seurat's method can be used on a large scale, fragile U.S. supply chains could be reimagined using low-cost “print depots” to manufacture parts domestically, at high volume, where and when they're needed.
Context: Today's metal 3D printing works by shining a laser onto a thin layer of metal powder, melting it and welding it to the layer below.
The digital design gradually takes shape as the layers accumulate and the object grows.
It's an extremely slow process, however. Even with multiple lasers, 3D metal printing hasn't accelerated fast enough to produce auto parts and consumer electronics in high numbers.
What's new: The technology from Seurat — named for the painter Georges Seurat, who studied the science of light and pioneered the style known as pointillism — speeds things up by splitting a single, high-powered laser beam into as many as 2.3 million beams of light.
A 30 kW laser is patterned with high-resolution images that can be programmed to block or let light through each of its pixels.
Every pixel defines its own laser spot, so the system can weld a large area of metal powder in an instant — allowing a multi-layered object to take shape 10 times faster than today's 3D printing technology.
"And it's not even the beginning of what we can do," Seurat CEO and co-founder James DeMuth tells Axios.
Seurat's technology, he says, is to 3D printing what the printing press was to pen and paper.
The backstory: The idea of pixelating a laser beam can be traced to the U.S. Department of Energy's Lawrence Livermore National Laboratory more than a decade ago, as DeMuth writes in a blog post.
He and other researchers were working on an entirely different problem — energy fusion — but the challenge was to design a reaction chamber that could withstand the extreme temperature swings that happen when lasers are used to produce energy.
After much trial and error, they adapted a patterned light method that was already in development at Livermore Labs for other purposes.
By 2015, DeMuth and Erik Toomre — a co-founder of Seurat — had proved that the technology would work for metal 3D printing, too. The company licensed the technology from Livermore Labs in January 2016.
What's next: Seurat, based in Wilmington, Massachusetts, says it has deals with seven of the world’s largest automotive, aerospace, energy and industrial companies to begin commercializing the technology this year.
The company has raised $78 million — including a $21 million Series B round extension announced Wednesday.
Its newest investors are Xerox Ventures and SIP Global Partners, which joined Capricorn’s Technology Impact Fund, DENSO, True Ventures, GM Ventures, Porsche Automobil Holding SE, Siemens Energy and Maniv Mobility.

Here is more support for the possibility of delivering affordable homes more rapidly using 3D printing. The reporter picked up on worker concern about being displaced, but the demand for skilled workers is far greater than supply at present, and for the foreseeable future.

Plus! The houses whose walls are set by the machine need all the fitting and finishing that any house requires, so there will be ** more ** work, not less, if sales of the new homes rise to match backed up demand.

Technology helps offer 3D-printed homes as an option for ownership
Melissa Hernandez
Sat, January 29, 2022, 6:00 AM·6 min read
For Apis Cor, a construction company based in Melbourne, Fla., building certain kinds of homes relies an awful lot on a key team member named Frank.
Frank has an arm that reaches more than 16 feet, said Anna Cheniuntai, the company's founder and chief executive, and can follow a computerized design blueprint while pushing out a steady stream of beaded construction material used to make walls.
Frank, you see, is a large, mechanical component of the technology used to build 3D-printed homes.
Proponents of the technology in recent years have pointed to 3D-printed homes as an innovative step toward addressing housing needs in the United States and elsewhere. Several projects are underway as communities cope with housing shortages and experiment with options.
The nonprofit housing organization Habitat for Humanity unveiled its first 3D-printed home in December in Williamsburg, Va., and is due to unveil another in Tempe, Ariz., in February.
"We're at the very beginning of 3D printing" said Janet V. Green, chief executive of Habitat for Humanity Peninsula and Greater Williamsburg in Virginia. "I hope that this does help some of the affordable housing crisis that we have across the nation."
Other examples exist inside and outside the U.S. In northern Italy, 3D-printed dome-shaped houses were made out of raw materials, such as clay. And in Dubai in the United Arab Emirates, the Dubai Municipality, a government building, stands as the largest 3D-printed structure in the world.
Here's some of what several construction business officials and observers described as key points to know about 3D-printed housing:
Homes built with 3D-printed technology use large-scale equipment for much of the construction, but also rely on traditional techniques for other basic needs of a home, such as roofing, electrical wiring, insulation and window installation.
Andrew McCoy, professor and director of the Virginia Center for Housing Research at Virginia Tech University, said a general idea of what to expect in the U.S. would be a 1,600-square-foot, three-bedroom, two-bathroom, 3D-printed home that sells for about $264,000 to $330,000. As with any home construction, factors such as the region where the home is built, floor plan design, number of stories, textures and finishes can change the price of the home.

Following up on the post by Mars_B4_Moon, here is a report on 3D Printed housing that seems well suited for Mars.

Instead of using the traditional straight walls, these Italian designers appear to be using the dome concept from Arabia.

They appear to be using locally sourced material to make the mortar for the printer, and that too seems similar to the ancient practices in Arabia.

The difference ** may ** be that the skill of the artisan is moved to the computer "brain" of the printer.

We definitely need machines like this on Mars from Sol 1.

My understanding is that 3D printing is used extensively in F1 racing now. That would suggest that issues over metal strength have been resolved.

Current and ongoing work by kbd512, in several interrelated topics may be pointing to opportunities for NewMars members (present and future) to develop 3D Printer construction plans ("stl" files) for the Trough Solar Collector systems he is designing.

The reflective surfaces must be supported by frames, and (happily) those can be made of plastic suitable for outdoor service, ** and ** equally happily, the systems kbd512 is designing are intended to make synthetic fuel, and the precursors for synthetic fuel can be directed into manufacture of plastic.

Thus, an major component of a Trough Solar Collector can be made entirely with solar power as the source.

The objection of some (including members of this forum) that "green" power solutions require fossil fuel is both valid and falsifiable.

While the initial set of devices to harvest renewable energy require(d) fossil fuel for their construction, it is absolutely NOT necessary to continue that destructive practice. As soon as human engineers can achieve the mind set of using renewable energy for ALL phases of construction of renewable energy harvesting equipment, the better for everyone.

This post was about using 3D Printers to make the framework for proposed Solar Trough energy Collectors ... the designs can be produced in scale, and then expanded to full size when customer orders are in hand. The objection of someone not familiar with 3D printers, that large 3D printers do not currently exist, would be in error. Huge 3D printers have been build and are working in multiple countries.

What is more, gangs of 3D printers can be swarmed to produce large objects in parallel and simultaneously. While I am not aware of any such swarms at present, the fact they can exist means (to me at least) that someone, somewhere is already developing them, or (more likely) ** has ** developed them, and we just don't know about it.

Update shortly after original post: The Chinese 3D Printer dam construction project would appear to be an example of a swarm design.
