More progress for tissue engineering.

Skin is one of the easier starting points for 3D bioprinting, the application of rapid prototyping technologies to the construction of living tissue. Since skin is a thin tissue, the challenging issue of producing the intricate blood vessel networks needed to supply inner cells with oxygen and nutrients can be skipped. Thin tissue sections can be supported in a suitable nutrient bath, and after transplant, patient blood vessels will grow into the new skin. Further, there is a fairly large and long-established research and development industry involved in various forms of skin regeneration. Numerous forms of prototype skin-like tissues have been created over the years, lacking many of the features of the real thing, but still useful in the treatment of, for example, burn victims. Further, skin structure is by now well understood, and considerable progress has been made in deciphering the signals and environment needed for suitable cells to self-assemble into the correct arrangements. All told, it should not be a complete surprise to see significant progress emerge in this part of the field.

The things that can be done with 3D printing never cease to amaze. To the casual observer with only a passing knowledge of the technology, it appears on the surface to be an interesting method of producing plastic odds and ends, and sometimes metal parts – but 3D printing is so much more, as anyone who follows the progression of the technology on a regular basis knows. The things it is capable of producing are often hard to wrap one’s mind around – especially when you look at 3D printing on the nanoscale.

A group of scientists from Lithuania, France and Australia are busy studying 3D printing on a very small scale. As a newly published paper entitled “Optically Clear and Resilient Free-Form μ-Optics 3D-Printed via Ultrafast Laser Lithography” explains, 3D printing is capable of creating functional objects that are impossible to produce via conventional manufacturing techniques, and structures at the miniature, micro- and nanoscales are no exception.

HOUSTON, Jan. 18, 2017 /PRNewswire/ — Made In Space and Axiom Space today, announce an agreement to be users and providers of one another’s capabilities to manufacture products in space. Made In Space is the only company to produce 3D printed products in Space and Axiom Space is the leading developer of the world’s first privately-owned commercial space station. This collaboration signifies Made In Space’s exciting transition from research phase, to manufacturing for commercial customers.

The companies have been working out the logistical elements of in-space manufacturing, outfitting the in-space factory with equipment, utilities, power, and thermal management to answer customers’ growing demand. In parallel to the manufacturing element, the companies are working together to plan the delivery of completed products to Earth, ensuring their quality during flight and upon arrival.

Researchers at MIT have developed a method of altering 3D printed objects once printed. The technique involves using light in order to adapt the chemical structure of a 3D printed material. This allows the creation of more complex objects which could be molded together, softened, or even enlarged.

The university is a hub of 3D printing research. Recently announcement include their Computer Science and Artificial Intelligence Lab creating the ‘photoshop for 3D printing’. The ‘Foundry’ software was developed in order to make use of 3D printing’s advanced capabilities over conventional manufacturing techniques. Also addressing 3D printing technology, MIT researchers looked at using 3D printing to investigate how graphene might create the strongest material ever.

The newly published paper is called ‘Living Additive Manufacturing: Transformation of Parent Gels into Diversely Functionalized Daughter Gels Made Possible by Visible Light Photoredox Catalysis’ and available in the ACS Central Science Journal.

California-based commercial aerospace company Moon Express, are on track to send their Electron rocket to the Moon in 2017. The Electron is propelled by 3D printed engines made by Rocket Lab, headquartered in Los Angeles. The project is designed for Google’s modern-day space race: the Lunar X Prize.

3D printed engines

Nine liquid-propellant Rutherford engines are behind the Electron. The rocket engines, the first to use 3D printing for the all core parts, use kerosene and liquid oxygen (LOX) for fuel.

If you were to pick one emerging technology with the potential to have a massive positive impact on humanity in the coming years, there’s a good chance you’d go with 3D bioprinting.

The ability to use “bio-ink” to print out biomaterials ranging from heart tissues to bone and cartilage is incredibly exciting — although at present it’s not exactly the most user-friendly of tech.

One company hoping to change that is Cellink, which this week has announced the launch of its new Bio X printer, which it hopes will bring 3D bioprinting to a whole new audience.

A while ago I got an idea: how awesome would it be to use 4D ultrasound to scan my unborn baby and make a VR experience of that. So I talked my girlfriend over even though the idea felt a bit weird and almost scary.

How to make it happen? I searched for similar cases online, but couldn’t find any. All I could find was some examples of using ultrasound images for a 3D print of your unborn baby. So this was the first time in the world someone was doing this. Luckily I got people at the Aava Medical Centre excited about the idea, and they helped me forward. I also contacted GE, a manufacturer of 4D ultrasound systems, and they advised me how to extract the right kind of files from the ultrasound machine.
