After 3D-printing a mouse thyroid gland and successfully transplanting it last year, Russia’s 3D Bioprinting Solutions is aiming to make a human kidney by 2030, the company’s scientists told Sputnik.

Lenses with a surface accuracy in the nanometer range are behind ever more accurate laser and optical systems. Manufacturers depend on ultra-precise optical and mechanical ablation processes, innovative coating processes and extremely accurate measuring technology to venture into these nano-worlds. The latest trends in optical manufacturing will be showcased by the world’s leading trade fair LASER World of PHOTONICS, from June 26–29, 2017 in Munich.

The diversity of lenses, their shapes, sizes and materials is growing all the time. Applications in non-visible wavelengths from x-rays and ultraviolet to the far infrared also require special optics, such as material processing using short pulse and ultrashort pulse lasers or imaging techniques in the medical and research fields and industrial quality control.

A collaboration between Russia’s Foundation for Advanced Research Projects and the Central Scientific – Research Institute for Precision Machine Engineering known as TSNIITOCHMASH has produced 3D printed bullets.
The Foundation formed in 2012 serves as an advanced research facility for military projects, an equivalent of the American DARPA. The project, conducted by the Foundation’s Laboratory of Additive Technologies and Design materials used selective laser melting technology to create an experimental batch of bullets. This same batch of bullets was then successfully fired.
According to the head of the laboratory, Doctor of Physical and Mathematical Sciences, Professor Vladimir Chuvildeeva, the current development team was formed more than ten years ago at the University of Nizhni Novgorod. The team has become specialized in developing laser alloying technology to develop complex physical models. Their end goal is being to develop equipment much more sophisticated for military purposes.

A woman living on a dialysis machine is grown a new kidney using her own cells. A father struggling with age-related vision loss has his eyesight restored. A soldier suffers extensive burns and has his skin regenerated.
This is a glimpse of the holy grail of regenerative medicine. The ultimate goal of the field is to develop therapies that restore normal function to diseased tissues and organs. Advances in 3D bioprinting, the process of fabricating functional human tissue outside the body in a layer-by-layer fashion, have pushed the envelope on what is considered possible in the field.

In Brief:
- New artificial blood vessels were able to grow with the recipient in recent animal testing
- Researchers saw a 56% increase in diameter made of patients’ own cells.
We have sufficiently advanced medicine to the point that artificial body parts are no longer science fiction. In fact, we may even start 3D printing organs, or have them grown in a lab. However, their artificial nature often means they won’t grow with a patient. For example, children need to undergo repeated surgeries until adulthood to replace implants they have outgrown.

Bioprinting is becoming more sophisticated daily. Students from Munich, Germany, hacked an Ultimaker 2+ to 3D print biomaterials even more efficient. Without a doubt, the yearly iGEM challenge is one of the yearly highlights for students in the field of biology, biochemistry, and biotechnology.

If I have a very robust and sophisticated 3D/ 4D printer to make my own clothing, accessories, household furnishings plus another option in my printer/s to make dishware, household accessories, etc. Why would I ever need a Macys, Bed-Bath, etc. as well as Amazon for that matter for clothing, etc. Hmmm, and retail was already worried over Amazon and Aliexpress, etc.
We’ve followed Nervous System for two years now, with their stunning introduction of 4D printed apparel. Based in Somerville, MA, the design team has since offered numerous projects to the world, featuring their 3D printed Kinematics dress on more than one instance from the first one now permanently ensconced in MOMA to debuting their last in a Sydney Museum. And while we’ve reported on the innovation of their adaptive materials along with an overview of their construction in collaboration with Shapeways, now we are allowed to take a more comprehensive look from the present, as others look much further into the future.
Dutch TV channel NPO gave their viewers a thorough view at how the Kinematics dress is made, from the scanning process to the next step which is to choose the material and shape of the clothing, and then on to the actual 3D printing. You’ll see that the hosts are very excited about the process, and while unless you speak Dutch, you won’t understand a word, it’s easy to understand what’s going on and why everyone is so enthusiastic. The episode came about as both the Nervous System team and Shapeways came together again, and actually created a whole new Kinematic Petals Dress for the special.
As they highlighted the world of high-tech in ‘Netherlands in 2050,’ the hosts truly did bring the dress to life as rather than just explaining what happens, they showed us, with host Rachel Rosier enjoying the process firsthand at the Shapeways’ facility in Eindhoven. Keep in mind, again, that these dresses are in demand for the permanent collections of museums.
Society is about to take another big step into the age of space-based manufacturing.
Early next year, California-based startup Made In Space plans to launch a machine to the International Space Station (ISS) that will produce ZBLAN optical fiber.
ZBLAN has the potential to be much more efficient than the silica-based fiber currently used in the internet and telecommunications industries, but it’s tough to make here on Earth because the planet’s strong gravitational pull induces imperfections in the ZBLAN crystal lattice, Made In Space representatives said.
