How AM can help fight climate change (Authentise Weekly News-In-Review – Week 34)

Climate change is caused by a great many aspects of human activity and one of the most impactful is manufacturing. In 2015, 21% of total greenhouse gasses emissions by the US was due to the industry sector. The manufacturing economy needs to be drastically reshaped in order to hamper the effects of climate change. Thankfully, technologies like AM are providing new avenues of production to do that. 3D printing enables production lines to be more flexible, reducing manufacturing to its most essential. Nonetheless, studies report that the energy consumption of some 3D printing methods are not up to their reputation, still needing some development in order to deal with material and energy usage. All the while, biopolymers are taking a hold in AM, proposing improved mechanical properties with the much needed value of being biodegradable.

 

Who Needs The Paris Climate Accords When You Have 3D Printing?

At the center of [digital manufacturing] technologies is 3D printing, which uses digital files to drive smaller, more flexible production lines than are economical with conventional manufacturing. 3D printing is still developing and is only now spreading to mass production. But in the next five to 10 years it should account for a sizable share of industry. As it matures, it will improve companies’ environmental performance in multiple ways.

Discovering Opportunities For Biopolymers In 3D Printing

[…] the few printable thermoplastics made from biological materials have limited applications, leading to concerns over environmental issues similar to those faced in conventional manufacturing. New biopolymers currently in development for conventional manufacturing can provide interesting opportunities for expanding biopolymer use in 3D printing applications.

3D Printing: A Boon Or A Bane?

Good prints require a ratio of 20– 50% virgin material to previously used powder to avoid problems, so a significant amount of waste is generated with each build. Another common claim is that 3-D printers are more energy-efficient than other manufacturing technologies. This claim is highly questionable because 3-D printers vary so dramatically in their energy use. A 2011 study measured the electricity use per kilogram of material deposited using several different 3-D printing methods and found that some printers used up to 80 times more energy than others.

Our Autonomous, Decentralized Future (Authentise Weekly News-In-Review – Week 19)

Ever since the first applications in the Ford automotive pipeline, industrial automation has taken giant steps in assuring a both voluminous and efficient production process. Nonetheless, the centralized framework on which it has thrived does no longer provide an optimal economy for today’s hyper-connected society and infrastructure. Highly automated systems are being put in place to intelligently tackle manufacturing issues, capable of addressing objectives in a decentralized manner. IIoT is a prime example of this, where edge computing combines data collection, analysis and action outside the realm of influence of a central authority. An open source framework, coupled with a mix of microservices is a sound answer to what the future of industrial automation might be. Similarly, AM’s flexible nature is making it possible to rethink manufacturing operations. Small, low-cost machines can work autonomously and in parallel in order to manage various production orders intelligently. Even more farsightedly, Siemens envisions swarms of 3D printing robots capable of subdividing bigger prints into smaller units, working in-situ.

In order for the [IIoT] to truly take off, connecting devices to the cloud—or on the edge of the network— needs to be fast, easy and affordable. It is also important that the suppliers of automation technology embrace open standards so that these “things” are interoperable. […] This week, Opto 22 takes its commitment to open standards a step further with the announcement that it has joined The Linux Foundation as a silver level member. According to Opto 22, this strategic move is the company doing its part to “spearhead the adoption of open-source technology in the industrial automation and process control industries, and accelerate the rollout of Industrial Internet of Things application.”

Markforged plans large-scale digital metal manufacturing with 3D print farms

The future of metal 3D printing is in print farms says Markforged CEO, Greg Mark. While a number of companies are attempting to create machinery capable of industrial metal 3D printing, Greg Mark believes these “large-format metal printers will be replaced by smaller, low-cost machines working in parallel – print-farms.”

3D metal print-farms will shorten development time, closing the gap between prototyping and production.

Markforged intends to develop a system that allows for rapid production of strong metal parts. For Markforged, farming is the solution for large scale metal 3D printing production. Currently, 3D printing farms are mainly working with plastics.

Siemens Contemplating “Swarm” 3D Printing?

Siemens’ experimental production robot.

A report on Forbes details work undertaken by Siemens to develop a “mobile robotic 3D printer” concept. The curious-looking small robot was developed last year and since then has served as an experimental platform for developing software for future production use.

[…] some day, the same software that is helping the robotic spiders crawl the floor while avoiding obstacles and keeping their printing parts in balance could enable whole new systems of factory work – on tasks much more complex than assembling handheld toys.

For example, a team of robots could work together on a new kind of fuselage cylinder for airplanes. If each robot could attack the job from a different angle, they might build complex shapes together that no single printer could create by itself.
