AM’s Symbiotic Relationship with Light Studies (Authentise Weekly News-In-Review – Week 09)

Hi everyone, and welcome to this week’s edition of Authentise News-In-Review!

This week we take a moment to marvel at the wonderfully symbiotic relationship between AM technologies and the study of light, or photonics. AM research is enabling scientists to work with entirely new materials with properties that are offering new ways to interact with nature and study our world. In exchange, our refined knowledge of photonics, empowered by this lengthened list of tools at our disposal, is fueling innovation within AM  technologies, pushing them to work faster, more reliably and accurately than before.

Here’s to light. Let’s dive in.

This Super-Fast 3-D Printer Is Powered by Holograms


[…] The basic principle here is an established 3D printing technique that uses lasers to cure a light-activated monomer into solid plastic. But unlike other approaches, which scan a laser back and forth to create shapes one layer at a time, this system does it all at once using a 3D light field—in other words, a hologram. It could make 3D printing far faster. The advantage of Daqri’s [a startup that designs and builds augmented-reality devices out of laboratories in San Francisco and in Milton Keynes, U.K.] chip, the company says, is that it can create holograms without the need for complex optics. On a silicon wafer, a tiny grid of tunable crystals is used to control the magnitude and time delay, or phase, of reflected light shined at the surface of the chip from a laser. Software adjusts the crystals to create patterns of interference in the light, resulting in a three-dimensional light field.

3D printed ceramic “butterfly wings” add color to photonic research

In a paper published in Nature Communications, physicists demonstrate the ability to reproduce the reflective structure of a butterfly wing through 3D printed gyroids. The discovery was made through the study of photonics – how light moves through space and objects – and has resulted in the patenting of a new material. […] Through a 3D printed gyroid, the researchers at Surrey and San Francisco demonstrate an ability to manipulate the photonic band gap through the shape of their ceramic object.

3D printing meets lasers in latest stem cell research

New research from Vilnius University in Lithuania combines laser writing and 3D printing to create more efficient micro-structures for the culture of stem cells. With computer aided design, biologists can specify structures that will allow cells to grow in a particular way, i.e. to form the pore-structure of the skin, or the cylindrical tissue of a vein. As to be expected, getting the right shape and form is a delicate process. The research from Vilnius University adds laser precision to such 3D microfabrication.

As a bonus article, here is our CEO Andre Wegner talking about the cloud, IIoT and the need for IT and OT to communicate.

Authentise CEO Bears Witness to OT, IT Folks Playing Nice in Cloud

Analytics is just the beginning of the IoT journey for manufacturers. There are already positive examples of machine control via the cloud. Authentise CEO Andre Wegner delivered that glimmer of hope tonight to more than a handful of people gathered around one of several topic tables at the Hard Rock Hotel in San Diego’s Gaslamp Quarter, the venue chosen to kick off Industry of Things World USA 2017. […] Authentise provides systems “to customers who are comfortable with a managed cloud, as well as those who are deciding to host it on premise,” he said. “We do what the customer wants, and are seeing about an even split in public cloud adoption. That’s probably more than most since industrial 3D printing is a new market and devices are most often already connected.”
