3D printed houses bring the benefits of additive manufacturing to the construction space. The material costs incurred by construction 3D printing are usually an order of a magnitude less when compared to conventional methods. This is while we take into account the fact that 3D printing concrete tends to be more expensive than normal construction concrete.

As for labor costs, they drop down basically to the daily wages of at most two or three operators. And that too is for a much shorter length of time as the 3D printed house would be ready for finishing and furnishing in days instead of months.

The cost to build an average sized 3-bedroom house with conventional building methods is from $250,000 to $320,000. Building the same home with 3D printing technology would cost from 20 percent to 40 percent less to build. So that same 3-bedroom house would presumably cost between $140,000 to $240,000 to build with 3D printing technology.

It should be noted at this point, that most construction 3D printers will not build, or 3D print the foundations, nor would the construction 3D printer be of any cost-saving benefit when it comes to roofing the house.

All those things: the roof, the windows, the doors, electrical wiring, paint and finishing – all of these costs remain the same as with a conventional house, as all this fall outside the scope of what a construction 3D printer is capable of.

Researchers at Harvard Medical School and Sichuan University have developed a novel means of 3D bioprinting live human muscle-tendon tissues. 

As opposed to normal extrusion bioprinting, which involves depositing cells along X and Y axes, the team’s ‘cryo-bioprinting’ process sees them frozen and stacked vertically, in a way that allows for the creation of freestanding, mixed-cell tissues.

According to the scientists, their technique also yields tissues that are more robust and versatile than those produced via conventional bioprinting, particularly when it comes to those anisotropic in nature, thus they say it could now find regenerative medicine, drug discovery, or personalized therapeutic applications.

Researchers from the Singapore University of Technology and Design (SUTD) have developed a new method of 3D printing with okara, a byproduct of soybeans created during the production of soy milk and bean curd. The approach is based on the direct ink writing process and is novel in that it requires no thickening agents whatsoever.

Elsewhere, Barcelona-based food tech startup Novameat has developed a new blue 3D printed steak. According to the firm, the vibrant product is the first meat alternative to combine all five kingdoms of classification, with a novel hybrid recipe containing animal cells, plant-based derivatives, fungi, algae, and spirulina.

“We chose the color with the purpose to create a futuristic-looking prototype,” said Guiseppe Scionti, CEO of Novameat. “We wanted to show that there are no limits. With our technology, we are able to create whole cuts and hybrid alternative meat products with a variety of ingredients.”

Researchers at University College London (UCL), Universidade de Santiago de Compostela (USC) and biopharma firm FabRx, have managed to convert an everyday smartphone into an on-demand personalized drug 3D printer. 

Using the visible light created by a mobile phone screen, the modified M3DIMAKER LUX system has already proven capable of 3D printing blood-thinning tablets in specific shapes, sizes and dosages. Operable via a user-friendly app, it’s hoped that with further R&D, the team’s machine could be deployed in future by those living in isolated areas, under the remote supervision of GPs to ensure patient safety. 

“This novel system would help people who need precise dosages that differ from how a medication is typically sold, as well as people whose required dosage may change regularly,” said the study’s lead author Xiaoyan Xu. “The tablet’s shape and size are also customizable, which enables flexibility in the rate at which the medication gets released into the bloodstream.”

An international team of scientists led by Cambridge University’s Cavendish Laboratory has used 3D printing technology to develop a novel set of microscopic nanomagnets.

Created using a custom 3D printing process, the nanomagnets are in the shape of a DNA-inspired double helix. According to the research team, this unconventional structure lends itself to strong magnetic field interactions between the helices in a manner never seen before. Specifically, by twisting around one another, the 3D printed helices produce nanoscale topological textures in the magnetic field they generate.

The team believes it can harness this phenomenon to closely control magnetic forces at the nanoscale, paving the way for ‘next generation’ magnetic devices.

Claire Donnelly, first author of the study, explains, “This new ability to pattern the magnetic field at this length scale allows us to define what forces will be applied to magnetic materials and to understand how far we can go with patterning these magnetic fields. If we can control those magnetic forces on the nanoscale, we get closer to reaching the same degree of control as we have in two dimensions.”

Inspired by the potter wasp, an Italian architecture firm has used 3D printing to make the domed, beehive-like structure of a house out of zero-emissions clay in the hope of showing what heights of sustainability can be reached with the technology.

Like the industrious wasps, the houses are made using the clay from wherever they are being built, which also means if they have to be knocked down, the only waste is the plumbing, gas, and electrical components.

New “living materials” could be used to make new objects ranging from small medical devices to skyscrapers.

By Neel V. Patel

The hype around 3D printing shows no signs of waning anytime soon, and for good reason: It’s a fast, inexpensive way to manufacture all kinds of different objects and structures, especially when conventional building materials are unavailable. A few scientists have a radical idea for what the next big leap in 3D printing could be: making things using living microbes.

Yes, it sounds weird as hell and not just a little creepy, but stay with us here. A group of researchers in the U.S. have just proved it’s possible to create 3D printed structures using E. coli. These “living materials,” illustrated in a new Nature Communications paper, could pave a path for more sustainable construction of objects that could also be programmed to help improve people’s health or remove toxins from the environment.

“Our group has always been interested in engineering biology to make materials,” Northeastern University chemist and study co-author Neel Joshi told The Daily Beast. “In the same way that a seed has a set of genetic instructions to produce a tree, we want to provide biological cells with a set of genetic instructions that program them to make material structures with prescribed properties.”

CTIBIOTECH is producing hundreds of CTISkin models for the NOVOPLASM project

By HAYLEY EVERETT

The NOVOPLASM consortium has announced it is the “first in the world” to develop cold plasma technology for the treatment of infected burns and the wound healing of skin grafts.

Regenerative medicine firm CTIBIOTECH, the French Armed Forces Biomedical Research Institute, École Polytechnique and Institut Pasteur make up the consortium, which is leveraging an immunized human skin model produced by 3D bioprinting to aid the development of the cold plasma treatment.

CTIBIOTECH claims to be the first in the world to 3D bioprint complete immunized human skin, called CTISkin, and is providing hundreds of models to the consortium to enable it to validate its cold plasma technology.

“Regenerative medicine is the future of healthcare,” said Professor Colin McGuckin, President and Chief Scientific Officer of CTIBIOTECH. “At CTIBIOTECH we advance these models to help personalized medicine and to support hospitals in the short term, not just the future. NOVOPLASM uses our models to accelerate new devices to protect human health.”

In Austin, construction of the largest 3D-printed neighbourhood will begin in 2022.

Will the future of housing and construction involve 3D printing? In a city in the US state of Texas, a new kind of real estate project will break ground in 2022.

An entire neighbourhood of 100 single-storey, 3D-printed homes will be built in an Austin neighbourhood. This method of construction is faster, cheaper and less polluting than conventional construction methods, according to the three companies behind this unique project.

This development is set to be the largest neighbourhood of 3D-printed homes ever built. Behind this project of unprecedented size are Danish architecture firm Bjarke Ingels Group (BIG), home building company Lennar and 3D printing construction technology company ICON.

Chef Amir Ilan prepares a lab-grown steak during a presentation by Aleph Farms, in Jaffa, Israel, in 2019. The company unveiled the first 3D-printed rib-eye steak on Tuesday.

By LAURA REILEY The Washington Post

An Israeli company unveiled the first 3D-printed rib-eye steak on Tuesday, using a culture of live animal tissue, in what could be a leap forward for lab-grown meat once it receives regulatory approval.

During the coronavirus pandemic, alternative protein products have soared in popularity, prompting nearly every multinational food corporation to hasten to bring its own versions to market. Frequently plant-based products have been patties or processed nuggets — “everyday” foods easier for companies to produce — that aim to ease the climate effects of the worst offender: Americans eat nearly 50 billion burgers a year, according to the U.S. Department of Agriculture.

Aleph Farms’ new 3D bioprinting technology — which uses living animal cells as opposed to plant-based alternatives — allows for premium whole-muscle cuts to come to market, broadening the scope of alt-meat in what is expected to be a rich area of expansion for food companies. A survey of more than 1,000 U.S. adults, conducted by MRS research for agriculture company Proagrica, showed that 39% of American consumers have considered going vegetarian or vegan since the pandemic began. Health concerns, climate change and animal welfare are drivers.
