New 3D printing method could jump-start creation of tiny medical devices for the body

Posted by in categories: 3D printing, biotech/medical

Researchers at the National Institute of Standards and Technology (NIST) have developed a new method of 3D-printing gels and other soft materials. Published in a new paper, it has the potential to create complex structures with nanometer-scale precision. Because many gels are compatible with living cells, the new method could jump-start the production of soft tiny medical devices such as drug delivery systems or flexible electrodes that can be inserted into the human body.

A standard 3D printer makes solid structures by creating sheets of material—typically plastic or rubber—and building them up layer by layer, like a lasagna, until the entire object is created.

Using a 3D printer to fabricate an object made of gel is a “bit more of a delicate cooking process,” said NIST researcher Andrei Kolmakov. In the standard method, the 3D printer chamber is filled with a soup of long-chain polymers—long groups of molecules bonded together—dissolved in water. Then “spices” are added—special molecules that are sensitive to light. When light from the 3D printer activates those special molecules, they stitch together the chains of polymers so that they form a fluffy weblike . This scaffolding, still surrounded by , is the gel.

Scientists: We Could Build Mars Shelters Out of Insect Polymers and Martian Soil

Like Concrete

In simpler terms: the resulting material “feels like concrete but much lighter,” Fernandez told CNN. “Very light rock.”

“We have a route to… manufacturing buildings to tools from 3D printing to mold casting with just one single material,” he added.

Ultra-fast 3D bioprinter makes body parts in a flash

Volumetric Bioprinting


Recreating human body parts using a 3D printer. This is possible in the Netherlands with the new bioprinter developed by Utrecht University and UMC Utrecht. This printer can be used to make models of organs or bones, amongst other things. These printed models can be made up of living cells on which medication can be tested, for instance.

Conventional 3D printers work by stacking plastic layers on top of each other. This build-up of layers creates a three-dimensional figure. There are already countless possibilities with these standard 3D printers. Science has been looking for years at how this technique can be applied across different areas.

Cryogenic 3D Printing Improves Bioprinting for Bone Regeneration

Posted by in categories: 3D printing, bioengineering, bioprinting, nanotechnology

Researchers from China continue in the quest to improve methods for bone regeneration, publishing their findings in “Cryogenic 3D printing of dual-delivery scaffolds for improved bone regeneration with enhanced vascularization.”

A wide range of projects have emerged regarding new techniques for bone regeneration—especially in the last five years as 3D printing has become more entrenched in the mainstream and bioprinting has continued to evolve. Bone regeneration is consistently challenging, and while bioprinting is still relatively new as a field, much impressive progress has been made due to experimentation with new materials, nanotubes, and innovative structures.

Cell viability is usually the biggest problem. Tissue engineering, while becoming much more successful these days, is still an extremely delicate process as cells must not only be grown but sustained in the lab too. For this reason, scientists are always working to improve structures like scaffolds, as they are responsible in most cases for supporting the cells being printed. In this study, the authors emphasize the need for both “excellent osteogenesis and vascularization” in bone regeneration.

More laser power allows faster production of ultra-precise polymeric parts across 12 orders of magnitude

Posted by in categories: 3D printing, information science, nanotechnology

A high-power laser, optimized optical pathway, a patented adaptive resolution technology, and smart algorithms for laser scanning have enabled UpNano, a Vienna-based high-tech company, to produce high-resolution 3D-printing as never seen before.

“Parts with nano- and microscale can now be printed across 12 orders of magnitude—within times never achieved previously. This has been accomplished by UpNano, a spin-out of the TU Wien, which developed a high-end two-photon polymerization (2PP) 3D-printing system that can produce polymeric parts with a volume ranging from 100 to 1012 cubic micrometers. At the same time the printer allows for a nano- and microscale resolution,” the company said in a statement.

Recently the company demonstrated this remarkable capability by printing four models of the Eiffel Tower ranging from 200 micrometers to 4 centimeters—with perfect representation of all minuscule structures within 30 to 540 minutes. With this, 2PP 3D-printing is ready for applications in R&D and industry that seemed so far impossible.

Drone Carries Freight To Offshore Oil Platform

Posted by in categories: 3D printing, business, drones, robotics/AI

A Camcopter S-100 drone made the first commercial drone delivery to an offshore oil platform in late August and it might be the beginning of a major industry. The helicopter drone flew a 3D printed part from Norway to a rig located about 60 miles off the coast. The flight was conducted without any special airspace adjustments and the drone was just part of the traffic servicing the oil fields. The drone also did an exterior inspection of the drilling platform and performed a simulated search and rescue drill with the rig’s standby vessel.

Of course, the oil companies are keeping a close eye on the drone developments because hauling freight and supplies to the rigs by drone could not only be a lot cheaper, but also safer. There are also several major helicopter companies that have oilfield supply as their core business watching the new initiatives. Servicing oil platforms is a multibillion-dollar business and also one of the most dangerous forms of commercial flying. Nordic Unmanned, which flew the first drone flight, says drones are a viable alternative to many missions now flown by big, expensive helicopters. “This marks the beginning of a new chapter within unmanned logistics,” spokesman Pål Kristensen said.” The technology is proven and robust enough to implement in large scale and reduces the risk cost and environmental footprint drastically.”

Enriching humanity using astroelectricity

Posted by in categories: 3D printing, employment, nuclear energy, robotics/AI, solar power, space, sustainability

This is my second video presentation on the topic of GEO space-based solar power (astroelectricity). This was also given via video at a conference in Portugal on 22 Aug 2020. After a brief introduction to astroelectricity, the 24-minute presentation addresses how global astroelectricity will enable most of the 17 UN Sustainable Development Goals to be addressed and, especially, how affordable middle-class housing can be built. We are living in an exciting time (in a positive sense) where emerging technologies will enable us to push through these difficult times. The key is to undertake an orderly transition from fossil carbon fuels to astroelectricity and not be sidetracked by poorly developed “solutions” such as the Paris Climate Agreement and the Green New Deal.


The world needs a peaceful, orderly plan to transition from fossil carbon fuels to globally decentralized sustainable energy sufficient to enable worldwide middle-class prosperity. Nuclear power, wind power, and ground solar power—“solutions” often tied to the Green New Deal—cannot practically achieve this. Astroelectricity, generated in space by space-based solar power, can meet this need. This presentation builds on the “(Em)powering World Peace and Prosperity Using Astroelectricity” to discuss the global benefits that will arise from transitioning to astroelectricity.
