3-D-printed alloys

Posted on Updated on

In the opinion of Lead author and Ph.D. candidate from RMIT University’s School of Engineering, Carmelo Todaro, “the promising results could inspire new forms of additive manufacturing.
If you look at the microscopic structure of 3-D printed alloys, they’re often made up of large and elongated crystals.
This can make them less acceptable for engineering applications due to their lower mechanical performance and increased tendency to crack during printing.
But the microscopic structure of the alloys we applied ultrasound to during printing looked markedly different: the alloy crystals were very fine and fully equiaxed, meaning they had formed equally in all directions throughout the entire printed metal part.”

It’s more affordable housing, and it heats and cools the house with less energy, no more paying $150,000 and up for a really nice home, and it will bring back the concrete industry 🙏.

Wow!!! I’m amazed! I really got to do this 3d printing i have a few dream homes that i want to build. I’m glad i watched this. Pretty sure my homes would cost millions doing it the old ways. Thanks.

That is amazing. I like 3d printing too. I’m dreaming to have small 3d printing machine. Actually I discovered this in Qatar when I was working on my invention. we just prepared the 3d drawing and the machine did it. we add some drawing and reshaping and it was real. Making a houses by 3d printing is some thin i cant imagine but its looks like real too,

What about hvac, plumbing, electrical, insulation, etc?

You still need carpenters, plumbers, electricians and so forth to build out the rest of the house… this is just building the framework..
Likely mixed in w structural mud (concrete)
It’ll take longer
24 hours though I’m sure. Windows, insulation, painting, essential furnishing like a bathtub, plumbing, electrical wiring, blah blah blah… I don’t think the 3D printer will do any of that.
What is your opinion?

 

This building in Dubai is the largest 3D-printed structure in the world — and it took just 3 workers and a printer to build it

Carbon – President and CEO

Posted on Updated on

Carbon Appoints Ellen Kullman President and CEO, Dr. Joseph DeSimone Named Executive Chairman.
According to Kullman, “Today’s announcement is a great honor, I am privileged to have spent the last few years on the Carbon board working alongside Joe, one of the greatest entrepreneurs and scientists of our time. Joe has built Carbon into the world’s leading digital manufacturing platform, and as President and CEO of Carbon, I am excited to partner with Joe and build on the solid foundations he’s put into place.
According to Dr. DeSimone, “For the last six years, I have led Carbon as Chief Executive Officer and am enormously proud of what we’ve accomplished during my tenure. I know what we will accomplish under Ellen will be even more extraordinary. Ellen is the right person to lead Carbon today. She has broad experience across multiple businesses, cycles, and geographies. Her vision, outstanding leadership traits, and distinguished track record will continue to drive Carbon’s growth into the future. In assuming the Executive Chairman role, I will be able to focus on evangelizing the platform and driving adoption more widely.”

3D Printing for Footwear comfort

Posted on Updated on

According to Fabian Krauss, North American global business development manager at technology company EOS,“ [Footwear] is less regulated, so there are not nearly as many qualification hurdles as in other industries, making it easier to go to market. But you see a high cost pressure from the very beginning.”

A family permanently lives in a 3D-printed home

Posted on Updated on

A family permanently lives in a 3D-printed home, take a look at the ‘Yhnova project’ in France, according to Ville de Nantes, “Nantes has provided the site for a house, Yhnova Batiprint3D™, built in just a few days, thanks to a 3D printer. This innovation, of the University of Nantes, was made possible thanks to the pooling of know-how of different partners: scientists, industrialists, public and socio-economic actors.”

Do they keep the foam once the concrete is dry? I did not understand that part. Thanks in advance.

@Engineering Juice and the vacuum will work just fine, right, because it is a poor conductor?

3D Printed Building- Interesting Facts to Know

3D Printed Building- Interesting Facts to Know

image1[1]

We all remember the time, not so long ago when we had to hire workers to make a building and work on the project for days or months. The process costs so much and with each unexpected problem of the workers came an unexpected delay. The delayed construction and high costs created a need for the technologists to come up with a better idea. Thus, the 3d models for printing came into existence. 3d building printing gave rise to new horizons in the field of construction and manufacturing.

 3d printed buildings are built by using the technology of 3d printing as a means to construct houses and buildings in the most efficient and cost-effective method. This method has vastly been adopted by the Chinese and has also gained its worth in Europe. This makes sense because people are tired of bearing high expenditures, lengthy construction timings, and never-ending design processes. Today, 3d printing has enabled you to forget all these worries about people wearing yellow helmets and use robotic techniques for mechanical piping of concrete. So, a 3d printed building will save you from the trouble by giving you the perfect 3d model for printing.

Interesting facts to know about 3D printed houses:

  • Resolve the future homelessness

We see homelessness as one of the significant issues of humanity at present. According to estimates, homelessness can exceed up to 1.6 billion people living in the improper shelter by 2025. Building a house or building from scratch can cost people a lot. A building offering flats or hostels can save the problem by efficient working on buildings that save your cost. By replacing the traditional and lengthy methods of using bricks and mortar with automated robotic piping of concrete, one can save time and money while still reducing the problem of homelessness in society.

  • No need for bricks

image2[1]

As hard as it is to imagine, houses can today be made without using bricks and mortar. Bricks and mortar took more time and effort for the builders to work with, and it used to leave us for waiting the time for its completion. However, by using 3d printing, robots can pipe in the concrete step by step and even the building at the same time. This saves you the costs of buying all the material for construction and also protects from wasted time. 

  • Robots are your builders

There was once a time where it was hard for us to believe that humans can create robots one day. Today, we are at a stage where robots have become so efficient that they have become the new builders. The robots are very efficient, and they don’t need breaks like human workers. This saves more time, and work is also better than humans. The human errors are also removed to the greatest extent possible, and all humans need to do is to command the machine, and it will work for you.

  • Save the cost and time

Constructing a building is a full-time job. A building project needs to be carefully catered with and must be monitored to save it from defects and additional costs. By using 3d printing in the construction of buildings, you can save the value of the construction process by saving more time. It will also cut down the labour cost because all 3d printing needs is an initial investment, and the rest will be catered in the least possible time. Dubai today has been working on the 3d printed buildings and have been one of the most efficient working hubs for 3d printing worldwide. Thus, more and more people are adopting this new technology because it reduces costs by optimizing raw materials and useful results.

Thus, 3d printed buildings have become a new trend around the globe. People are willing to rely on robotic technology rather than humans with risky results. Robots can be left alone at the workplace without any check and balance and will work for creating a sustainable working environment.  

The only problems with 3d printed buildings are that it needs initial capital investment and also any defect in the robotic machinery can cost a lot to correct as well. Another problem with 3d printed buildings is the fact that it also reduces the job opportunities for builders and manufacturers. However, 3d printed structures are an effective way to meet the construction requirements in the minimum of time.
