Ultraprecise 3D printing technology is a key enabler for manufacturing precision biomedical and photonic devices. However, the existing printing technology is limited by its low efficiency and high cost. Professor Shih-Chi Chen and his team from the Department of Mechanical and Automation Engineering, The Chinese University of Hong Kong (CUHK), collaborated with the Lawrence Livermore National Laboratory to develop the Femtosecond Projection Two-photon Lithography (FP-TPL) printing technology.

By controlling the spectrum via temporal focusing, the laser 3D printing process is performed in a parallel layer-by-layer fashion instead of point-by-point writing. This new technique substantially increases the printing speed by 1,000—10,000 times, and reduces the cost by 98 percent. The achievement has recently been published in Science, affirming its technological breakthrough that leads nanoscale 3D printing into a new era.

The conventional nanoscale 3D , i.e., two-photon polymerization (TPP), operates in a point-by-point scanning fashion. As such, even a centimeter-sized object can take several days to weeks to fabricate (build rate ~ 0.1 mm3/hour). The process is time-consuming and expensive, which prevents practical and industrial applications. To increase speed, the resolution of the finished product is often sacrificed. Professor Chen and his team have overcome the challenging problem by exploiting the concept of temporal focusing, where a programmable femtosecond light sheet is formed at the focal plane for parallel nanowriting; this is equivalent to simultaneously projecting millions of laser foci at the , replacing the traditional method of focusing and scanning laser at one point only. In other words, the FP-TPL technology can fabricate a whole plane within the time that the point-scanning system fabricates a point.

NASA has tentative plans for a manned mission to Mars sometime in the 2030s. Between now and then, there’s still much that needs to be sorted. To start, massive dust storms, high levels of radiation, low temperatures and a lack of water make the Martian surface an unfriendly place for long-term visits. Taming it for human life will likely prove one of the most demanding and complex engineering puzzles in human history. With those extraordinary obstacles in mind, in 2015 NASA announced the 3D-Printed Habitat Challenge: an open call asking designers and architects outside the traditional aerospace industry to create plans for Martian living centred around 3D printing. One of 10 finalists announced in 2019, this plan from the design practices HASSELL and Eckersley O’Callaghan envisions teams of 3D-printing robots building a protective shield on the Martian surface several months in advance of a human landing. Upon arrival, astronauts would then work alongside the autonomous robots to piece together an inflatable, modular habitat.

I am in shock… Google suddenly as yahoo are allowing conjecture and mendacity be seen as public or scientific opinion. Here is another confused mind who towards the end of her rant quotes Christian scripture as basis to stop Life extension-Transhumanism???

When I say to these minds Behold the leader of Christianity stood for Life abundant-Super Longevity and I can prove such. No matter what lost evangelist or preacher tells you Jesus was a medical researcher of extraordinary magnitude…

NOW BEHOLD THE LOST in this article… https://www.rodofironministries.com/…/transhumanism-and-imm… Respect r.p.berry & AEWR wherein aging now ends we have found the many causes of aging and we have located an expensive cure. We search for partners-investors to now join us in agings end… gerevivify.blogspot.com/

Whether we like it or not, the hybrid age is already here. From genetic manipulation, to AI technology, to nano-technology, robotics, 3D printing, brain mapping, super computing, the list is literally endless. Futurists and Transhumanist philosophers believe that science and technology are limitless, and that humanity’s current cultural traditions and mindset are the mechanisms in place that prohibit human development.

3D printing technology is changing and will change pretty much everything. Besides printing the intermittent novelty project at home with a desktop printer, additive manufacturing or 3D printing technology is being used in a large group of businesses changing the manner in which we design, build, create, and even eat.

NASA is planning to use 3D printing technology to construct housing on Mars for future colonies while organizations like byFlow are using the emerging technology to create food and intricate edible tableware. The uses and applications appear to be both limitless and exciting, yet this is only the beginning. Things being what they are, what sort of changes can we expect to see in the medical industry?

“The Hyperloop exists,” says Josh Giegel, co-founder and chief technology officer of Hyperloop One, “because of the rapid acceleration of power electronics, computational modeling, material sciences, and 3D printing.”

Thanks to these convergences, there are now ten major Hyperloop One projects—in various stages of development—spread across the globe. Chicago to DC in 35 minutes. Pune to Mumbai in 25 minutes. According to Giegel, “Hyperloop is targeting certification in 2023. By 2025, the company plans to have multiple projects under construction and running initial passenger testing.”

So think about this timetable: Autonomous car rollouts by 2020. Hyperloop certification and aerial ridesharing by 2023. By 2025—going on vacation might have a totally different meaning. Going to work most definitely will.
