First-of-its-kind 3D-printed home blends concrete, wood | Cornell Chronicle

https://news.cornell.edu/stories/2022/0 … crete-wood

Their first-of-its-kind hybrid design connects structural elements composed of 3D-printed concrete with conventional wood framing representative of most U.S. residential construction. The combination shows how each material can be used where it works best, with minimal waste, to create buildings that are efficient, resilient against increasingly intense weather events and potentially more affordable.

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.

For Mars_B4_Moon re #328 Today 05:26:06

Thank you for finding and posting the link to a report on 3D Printing of steel that has properties similar to the traditionally manufactured product.  That sounds (to me at least) like a major breakthrough.

House Printed in Spain (with eggs and dirt)

https://3dprinting.com/news/house-print … -and-dirt/

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.

Globally known Italian bicycle manufacturer Pinarello has unveiled a new 3D printed bicycle, "Bolide F HR 3D."

Produced as the fastest one in its field, Italian track and road cyclist Filippo Ganna is preparing to use the bike for his upcoming attempt at the UCI Hour Record.

Pinarello says this enabled it “to introduce new shapes and features that are impossible to replicate” using existing carbon fiber construction techniques.

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

Thanks for the Update I had seen news on Autonomous drones, printed cameras and printed part for Construction and Flying 'Printers' but I didn't get time to post any news.

Very interesting developments keep happening, news coming out each week with Printing and artificial software AI that it is difficult to keep up with news.

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.
