You know we live in the 21st century where people are 3D printing of chicken and laser cooking. They got me to “3D print chicken”.

a article in NPJ Food Science explains how scientists combined additive manufacturing (aka, 3D printing) of food with “precision laser cooking,” which achieves “a higher degree of spatial and temporal control for food processing than conventional cooking methods ”. And, oh, by the way, the color of the laser is important (eg red is best for browning).

Very nice, but wake me up when they arrive replicators… What they will do. Meanwhile, other people are 3D printing not just individual homes, but entire communities. It reminds me that we haven’t quite realized just how revolutionary 3D printing can and will be, including for healthcare.

The New York Times profiled the creation of a village in Mexico using “an 11 foot high three dimensional printer”. The project, built by New story, a non-profit organization focused on providing affordable housing solutions, Throw it away, a Mexican social housing production company, and Icon, a construction technology company, is building 500 homes. Each house takes approximately 24 hours to build; 200 have already been built.

Here is a video of the process:

No one knows how durable the houses will be over time, but they have withstood a 7.4 magnitude earthquake before, which would have been appreciated, for example, in Haiti. Most importantly, they provide housing for people who might otherwise have been homeless or living in unsanitary conditions.

Brett Hagler, CEO and co-founder of New Story, said The temperature: “We know that being able to build faster, without sacrificing quality, is something we must take giant steps on if we are even to make a dent in the issue of housing in our lifetime. ”

“We are really looking at the biggest opportunities to have both impact and efficiency gains,” added Alexandria Lafci, co-founder of New Story. “There is a huge speed boost that you get with 3D printing, without sacrificing quality. “

There are 3D printed housing projects all over the world, including Austin, Texas, Rancho Mirage (CA), and Tallahassee (FL). Tallahassee Developers boasted: “Make no mistake, these homes are not your average test models. The finished product is far superior in terms of strength, durability and efficiency.

Faster, cheaper, more durable – what’s not to like?

The first 3D printed house in Canada, the so-called Fibonacci house, featured curved walls, simply because builders could. “So now architectural features that are exciting or add aesthetics can be achieved for virtually no cost comparison.” noted Ian Cornishin, president of the company that built it.

Here is their video:

This company, Twente additive manufacturing, now partners with a non-profit organization World Accommodation to create a 3D printed community called Sakura Place. Don McQuaid of World Housing said: “Our belief is that technology is going to be the solution to homelessness, and we believe that everyone deserves a home.”

The ruler of Dubai is such a big fan that he decreed that 25% of all constructions – not just houses – must be built by 3D printing technology by 2030, “to promote Dubai as a regional and global hub for the use of 3D printing technologies “.

It’s a new world for building. Housing expert Brad Hudson Noted: “The housing industry has not changed its overall methods of building homes over the past 50 years. Innovations like 3D and modular construction will start to gain popularity.

So it will be for health care. I have written before about 3D printing of prescription drugs, which offers the intriguing, if not frightening, possibility of printing your own drugs at home, but this is just one example of how healthcare is starting to realize the potential of 3D printing.

Scientists from the Israel Institute of Technology have 3D printed a network of blood vessels, to support the implanted tissues, which had not been achieved by conventional approaches. The researchers believe it is “a versatile and adaptable technique that may open a new path to patient-specific tissues grown entirely in the laboratory.”

Here is their video:

We are not yet at the stage of 3D printing human organs for transplants, but we are close, and in the meantime, we are 3D printing prostheses. NIH said:

3D printable prosthetics are changing the face of medicine as engineers and physicians are able to develop prosthetics that are fully personalized for the wearer. Consumer 3D printing is leading to an even bigger revolution: “DIY” assistive devices that can be printed by virtually anyone, anywhere.

Imagine this world.

Some connoisseurs think The healthcare 3D printing market is already a billion dollar market and will be $ 6 billion by 2030, which seems insufficient. Where is Dubai’s ruler of healthcare, demanding 25% of healthcare construction (or manufacture) using 3D printing by 2030?

3d printing helped to decrease the shortage of personal protective equipment (PPE) during the pandemic when demand soared as supply chains collapsed, but not quickly enough and not in sufficient quantity. Supply chains are tottering again, but if healthcare organizations increased their 3D printing capabilities to prepare for shortages, I missed it.

There are really two types of thinking that we have to practice here. One is what are the things we are doing now that could be done at least as well using 3D printing? It’s like building houses using 3D printing; they are not reinventing houses, but they are reinventing the way they are built, hoping for a faster and cheaper way. Ideally, this could lead to more affordable housing and perhaps drastically reduce the number of homeless people.

For example, in healthcare, more affordable and better fitting prostheses are produced much faster.

The second is what are the things that we can’t do now that could be done with 3D printing? Work in human organs, tissues or blood vessels falls into this category, but should not be the boundary of the category.

It’s pretty easy to see how 3D printing can be one of the things that helps us solve the problem of homelessness / affordable housing. How can it help us in the same way to solve the problem of people who do not have access to affordable health care / health care?
