Solving Supply Chain Issues with 3D Printing
https://www.designnews.com/3dp/solving- … d-printing

Persistent supply chain troubles are prompting North American manufacturers to seek supply production closer to home. One major solution is the production use of 3D printing. The additive manufacturing process allows for just-in-time inventory that is close at hand. Some manufacturers are turning to service companies, while others are setting up 3D print production in-house.

Re: 3D Printers

Researchers uncover how to 3D-print one of the strongest stainless steels
https://www.eurekalert.org/news-releases/965666



    A team of researchers from the National Institute of Standards and Technology (NIST), the University of Wisconsin-Madison and Argonne National Laboratory have identified particular 17-4 steel compositions that, when printed, match the properties of the conventionally manufactured version. The researchers’ strategy, described in the journal Additive Manufacturing, is based on high-speed data about the printing process they obtained using high-energy X-rays from a particle accelerator.

    The new findings could help producers of 17-4 PH parts use 3D printing to cut costs and increase their manufacturing flexibility.

This version of the building is built with Mediterranean climates in mind. It has a small volume to allow easy heating in winter, and expandable in the summer months to make use of its surroundings.

The walls contain cavities that permit airflow and allow great insulation to prevent heat loss in winter. The structure offers protection from solar radiation in the summer months too.

Bug-Like Flying 3D Printers Are A Powerful New Tool
Julian van der Merwe - Yesterday 3:00 PM

Close up of drone rotor

3D printing and additive manufacturing seem to be 21st-century goldmines, making waves in everything from jewelry and automotive manufacturing to construction in more recent years. Who would have thought that technology like 3D printing could be combined with two other emerging technologies — drones and AI — to make something truly remarkable?

A team of researchers from The University of Bath, led by Imperial College London, published a paper in the journal "Nature" that details a very tantalizing new construction tool: autonomous drones that work like insects to repair and potentially even build entire structures. The researchers dubbed the manufacturing method aerial additive manufacturing, or Aerial-AM for short.

The drones work on the same principle as extrusion 3D printers, which means they feature a print head that sits vertically over the workspace to place a stream of quick-setting material in layers on a surface. As the extrusion takes place, the print head moves to create the desired shape. Layers are added as needed to form a final product. We've seen large machines that deposit concrete to print small habitats; in the case of this new innovation, the researchers developed their own test materials described as cement-like, yet light enough for a drone to tote around.

Since this technology depends upon the presence of a robust (thick) atmosphere, it is difficult for (me at least) to imagine it would work well on Mars out of doors.  However, it ** should ** work well in a pressurized space, and it would not matter to these devices if the atmosphere is all CO2.

Therefore, our artistic members with the ability to show images in posts have an opportunity to imagine mud-hive structures inside lava tubes on Mars (or the Moon for that matter).

Re: 3D Printers

TH, that is a fascinating innovation.  The thin atmosphere of Mars is not neccesarily an impediment to flying drones if they are small.  The smaller something gets, the larger the ratio between surface area and volume.  Aerodynamic lift is a function of surface area.  This is how bees are able to fly with wings that are more like paddles than aerodynamic structures.  If bees were as large as people, or even as large as mice, they would lack the muscle power to fly.  For something as small as a mosquito, air is as viscous as syrup.

Another option is to have walking drones, rather like beatles.  These would be directly solar powered with PV cells lining their bodies.  The more sunlight available, the faster they work.  Parabolic structures like bee hive shapes can be built up without form work.  Nubian vaults can similarly be built without formwork.  Little robotic critters like this could build something like that using compressed regolith, or regolith with a chemical binder.

In most circumstances, I think this woukd be an expensive way of building.  But on Mars, where men would have to wear EV suits, it may turn out to be more cost effective than having astronauts in suits laying bricks.  The alternative, assuming we want to build a large number of identical structures, is to make some sort of reusable mold and cast the beehive.

Re: 3D Printers

The local 3D Printer User Group has been operating in hybrid mode since Covid, when all meetings were virtual.

The group leader is out of town, and the substitute leader did not set up the Virtual feed at the meeting site, so I've been holding up the Virtual service without any "customers".

It's a good opportunity to catch up on a variety of things, so I don't mind being "tied" to the feed for an hour.

Re: 3D Printers

The new Space Plane topic provides an opportunity to return to the use of 3D printers to make complex shapes.

https://www.nasa.gov/sites/default/file … _final.pdf

The article at the link above starts out reporting on experiments to 3D Print heat shields for space vehicles.

Regardless of how that article turns out (if someone has time to read it) this topic is available for discussion (or reporting) on the use of 3D printers to make custom heat shields for a Space Plane (or any vehicle returning from orbit).

I am specifically looking for reports of printing glass foam using a 3D Printer.

Unlike the Space Shuttle glass tiles, a 3D printer could print the entire side of a space craft, so it could be bolted onto a rectangular space craft body (or a cylindrical one since that configuration is so common in the aircraft industry).

DoD invests additional $1.5M toward 3D-printed hypersonic rocket engine

https://www.spacedaily.com/reports/Defe … e_999.html

The Department of Defense awarded a $1.5 million contract to New Frontier Aerospace to continue its work on a 3D printed rocket engine.

The aerospace manufacturer announced the deal in a press release on Tuesday with funding coming from the National Security Innovation Capital. The company is developing a plastic-fueled rocket engine called Mjolnir. Development began with a $750,000 contract from the NSIC in 2020.

The new contract will fund the development of the remaining parts needed to complete the engine. The company plans to run a final test - called a hotfire test - by May 2024.

"Based on NFA's performance in designing, 3D printing and testing the first, key component of the Mjolnir. full-flow staged combustion engine in less than a year, we are pleased NSIC sees the enormous potential in the continued development and completion of Mjolnir.," NFA CEO Bill Bruner said in a statement.

'SpaceX CRS-27, also known as SpX-27, a Commercial Resupply Service mission to the International Space Station (ISS) launched on 15th day of March 2023'

Investigation will test 3D printed materials for satellite manufacturing
https://www.spacedaily.com/reports/Inve … g_999.html

As 3D printed rockets, car parts, and even homes begin to hit the market on Earth, L3Harris Technologies aims to leverage the International Space Station (ISS) National Laboratory in its search for durable materials to 3D print satellite components. Before 3D printed materials can be used to build more sustainable and efficient parts for spacecraft, they must be tested to ensure they can withstand the harsh environment of low Earth orbit (LEO).

Among the payloads launching on SpaceX's upcoming 27th Commercial Resupply Services (CRS) mission is a project to test an L3Harris-designed 3D printed radio frequency (RF) circuit and various 3D printed material samples. The project is a continuation of a 2021 experiment on the ISS that collected two months of data.

This time, L3Harris will also test photonic material for a new technology called photonic integrated circuits. Used for satellite communications and similar to computer chips, these circuits utilize light instead of electrons in conventional electronics, similar to how light carries information in fiber optic cables for phone and internet data.

"We're excited to test the 3D printed materials for six months and compare the new results with previous ISS experiments and ground tests," said Arthur C. Paolella, senior scientist and technical fellow with L3Harris, an aerospace and defense industry leader. "The ability to 3D print materials for use in space opens up new possibilities for satellite design and construction while making spacecraft manufacturing more cost-effective and efficient."

Eduardo Rojas, director of the Wireless Devices and Electromagnetics Laboratory at Embry Riddle Aeronautical University, and his students are assisting with the experiment. The investigation will utilize the MISSE Flight Facility (owned and operated by ISS National Lab Commercial Service Provider Aegis Aerospace) mounted to the exterior of the ISS.

There, the material samples will experience the harshness of space in the ultimate test of their durability. The materials will be subjected to various conditions, including extreme temperatures and radiation, to validate their performance in the same environment where the satellites will operate.

"While we can test the durability of these materials on Earth against one or two of these factors at a time, on the ISS, we can test every potential hazard-and all at once," Paolella said.

Thank you for this encouraging update to Louis' long running topic.  It is good to see Louis' topics come back into view from time to time.

In this case, it occurred to me that the current hiatus in development of the Large Ship concept of RobertDyck might be given a small impulse towards restart by a vision of 3D printing the entire Large Ship.  The team working on assembly of Large Ship in orbit ran out of energy as it confronted the details of how to assemble flat plate (or coiled metal) in space to make ** just ** the floor of the rotating habitat.

Re: 3D Printers

Inside the 3D-printed box in Texas where humans will prepare for Mars

https://www.theguardian.com/science/202 … epare-mars

Watching four people spend a year in a 3D-printed box is Nasa’s next small step toward landing humans on the surface of Mars. Nasa says it hopes to send humans to the red planet as early as the 2030s. The first mission could be a nine-month trip one-way, and could leave the astronauts on the surface for two and a half years before starting the long trip back home.

Preparations for that trek are already well under way with the agency’s Artemis program. Artemis is sending astronauts back to the Moon for the first time since 1972, including the first person of color and woman to walk on another celestial body. As part of the Artemis missions, Nasa is also launching Gateway, a space station that will orbit the Moon and serve as a pit stop for Mars-bound missions.

Getting to the Moon means getting to Mars, and getting to Mars means testing the physical and behavioral health of a crew in isolation. That’s where Chapea comes in.
