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.

Week in Review: November 1st to 7th – Performance through Innovation

Hello everyone, here we go with another Week in Review.

This week we had a clear view at what AM can provide in terms of performance. Through new technologies and collaborations, we are seeing a future in which certain tasks simply couldn’t be accomplished in any other way. GE is testing a prototype engine with 35% AM parts, from 855 to just 12 with improved performance, Lockheed Martin explains how the company incorporated 3D printing to become world’s largest defense contractor and a collaboration between SSL and TUI will see a demonstration of kilometric structures in space through AM satellites. Additive solutions are driving performance parts in every industry:

GE unveils 35% 3D printed ATP engine: ‘more additive parts than any engine in aviation history’

General Electric (GE) has tested a demonstrator engine with 35% additive manufactured parts. The engine was made to validate 3D printed parts for the clean-sheet design Advanced Turboprop (ATP) engine … The all-new lightweight components for the ATP will contribute to a 5% weight reduction, as well as a 1% improvement in specific fuel consumption (SFC). 855 subtractive manufactured parts will be reduced to 12 additive parts, with those 12 making up 35% of the total part count.

Lockheed Martin Looks to Catch Up in 3D Printing

Lockheed Martin is making titanium propellant tanks for satellites using a Chicago company’s electron beam additive manufacturing technology.

Robert Ghobrial, additive manufacturing lead for the company’s training and simulation location in Orlando, FL, spoke at SME’s “Additive Manufacturing Applications: Innovations for Growth” seminar in October, at advanced energy technology accelerator NextEnergy, in Detroit. He traced his work with 3D printing back to 2012, when his team received some MakerBot printers that largely went unused. Along the way, Ghobrial coined the phrase, “The 5Ps of Additive Manufacturing™,” a manufacturing model that describes how AM can help aerospace, defense and other businesses.

“Trusselator” puts additive manufacturing into orbit

Tethers Unlimited Inc’s (TUI) Firmamentum division have announced a collaboration with Space Systems Loral (SSL) that will allow them to demonstrate their on-orbit manufacturing technology, specifically for building kilometer scale space systems. According to TUI, the primary benefit of this on-orbit fabrication is the improved packing efficiency and system mass, which basically means that [companies] can save trips to space by launching highly concentrated fabrication material instead of built on earth structures that have to be deployed in space.
