The Rise of Point of Use Manufacturing (Authentise Weekly News-In-Review – Week 66)

Additive manufacturing enables much more than design freedom and improved performance. It is one of the first technologies that is capable of bringing unparalleled production capabilities in a unified package. Through it, manufacturing doesn’t have to rely solely on factories: it can move from a centralized to a decentralized model. We have all the premises to enable point-of-use production to more nimbly address the requirements at a micro scale. There are a variety of cases that would greatly benefit from this added agility. Think a medical emergency which can’t wait for the logistics of tool manufacturing and handling from a 3rd party a great distance away. Having an AM hub near a disaster situation can help first responders address the situation quickly and efficiently. Already the US Navy is experimenting by including AM equipment on ships at sea, capable of autonomously print spare parts and tools, on-demand.

3D printing and the rise of point-of-care medical manufacturing

As a rule, the healthcare infrastructure doesn’t dabble in manufacturing, but that is changing in dramatic ways, and that transformation is enabled by 3D printing. A white paper published by SME (Dearborn, MI), a nonprofit organization promoting manufacturing technology, explains how point-of-care (POC) manufacturing is reducing healthcare costs while improving patient experience.

Plant Inspires 3D Printed Material for Cleaning Up Oil Spills

Salvinia molesta is a floating fern native to South America. Its leaves are extremely hydrophobic and retain a surrounding pocket of air when submerged in water, thanks to tiny water-resistant hairs. On a microscopic level, the leaf hairs align in a structure that resembles an egg beater or whisk. Using a method called immersed surface accumulation 3D printing (ISA 3D printing), the researchers [at the University of Southern California] were able to recreate this egg beater microstructure, called the Salvinia effect, using plastic and carbon nanotubes. The result was a material that was both highly hydrophobic and oleophilic, or oil-absorbing. The combination allows oil and water to be efficiently separated.

Full Speed Ahead: Using Additive Manufacturing to Repair Ships at Sea

When a ship runs into trouble at sea, it can be time-consuming and disruptive to take it ashore to get it fixed. A team of UConn engineers has now developed a way for a ship’s crew to pinpoint the exact location of any mechanical trouble on board and, instead of taking the ship offline for maintenance, to repair or replace the part while the ship is still at sea. The researchers, led by associate professor of materials science and engineering Rainer Hebert, have created a device that uses ceramics on additively manufactured metals to obtain signals about degradation or certain other potential problems, such as overheating. They are also developing a field-deployable manufacturing process that could produce replacement parts from electronic files using a 3D printer on board ship after the metal-ceramic parts indicate failure or problems.

Integrating the Future & the Present (Authentise Weekly 3D News Review – Week 51)

Hi all, welcome to another (festive!) edition of the weekly review by Authentise!

We hope you had a merry Christmas time! As we go back to our usual day-to-day, we gathered last week’s juiciest 3D news. Many companies are tackling the issues of integrating their work on new tech into present standards and workflows. Sounds like Organovo’s work on pre-clinical bioprinting is finally getting there, Oas are standards for AM enabled medical. Other times industrialization doesnt need to be so complicated: IIoT allows smaller, incremental steps to be taken to integrate new tech and practices to benefit businesses.

Let’s dig in.

Organovo 3D bioprinted liver tissue could make it to the FDA by 2019

Speculation on 3D printed tissue coming to humans sooner than we think is backed by new pre-clinical findings from 3D bioprinting company Organovo. Though it will still be 3–5 years before the U.S. based Organovo apply for clearance of their liver tissue, that is still sooner than perhaps even the FDA had in mind. Pre-clinical trial data shows that 3D bioprinted liver tissue has been successfully planted into lab-bred mice. The human liver-cell tissue shows regular functionality and, at this stage, is being explored as a suitable patch for the organ.

3D Printing Production Medical Devices — Pitfalls And Best Practices

In May 2016, the FDA released a draft guidance titled Technical Considerations for Additive Manufactured Devices. Any manufacturer or organization considering 3D-printed components during the development of a medical device should refer to this document. The guidance goes into detail regarding risk and other considerations related to 3D printing, as well as how to employ 3D printing within device development.

Use Existing Data to Optimize IIoT Sensor Deployment

It is hard to know where to start [in IIoT], and whether the solution being designed will be palatable to the end customer in terms of function and price. Rather than ordering highly marketed solutions from outside the enterprise and “tipping” consultants with exorbitant fees, they can find ingredients that are already on hand, apply basic analytics, and come up with some surprisingly tasty ways to translate raw data into process information to improve maintenance or business decisions.

Read about the useful, and easy, ways IIoT can easily be integrated in your business here.

 

We hope to see you next week for another edition brought to you by Authentise!
