Monitoring 3D prints – more than just a business boost (Authentise Weekly News-In-Review – Week 94)

We at Authentise are champions of the idea that 3D printing data must be exploited anywhere it is to be found. This often times comes from the printers themselves, offering KPIs on successful print rates and more. Yet even more information can come from external monitoring systems, which that can provide you with data from within the process itself. The benefits of running a monitoring system are numerous, from helping you identify, and potentially correct, issues from within the process, to giving an unprecedented look at still little-known physical phenomenons. Metal printing, for example, is still grounds of research, as we try to understand the dynamics of precise powder melting and the behavior of very hot particles. Another example would be to track 3D printed objects, based on the unique printing “signature” of each printer (like vibrational micro-defects), and thus being able to tell which printer produced it.

High-Speed Cameras Used to Monitor 3D Printing Process

In a thesis entitled “Process Monitoring for Temporal-Spatial Modeling of Laser Powder Bed Fusion,” a student named Animek Shaurya studies the use of high-speed video cameras for in-situ monitoring of the 3D printing process of nickel alloy 625 to detect meltpool, splatter, and over melting regions to improve the quality of the print.

New NIST method measures 3D polymer processing precisely

182682_web

Researchers at the National Institute of Standards and Technology (NIST) have demonstrated a novel light-based atomic force microscopy (AFM) technique–sample-coupled-resonance photorheology (SCRPR)–that measures how and where a material’s properties change in real time at the smallest scales during the curing process. […] Surprising the researchers, interest in the NIST technique has extended well beyond the initial 3D printing applications. Companies in the coatings, optics and additive manufacturing fields have reached out, and some are pursuing formal collaborations, NIST researchers say.

This is how researchers can now track 3D printed guns, weapons

screen-shot-2018-10-19-at-10-17-52

According to academics from the University of Buffalo, there is a way to use the ‘fingerprint’ of 3D printers to accurately trace items printed through the machinery, which may include counterfeit goods, guns, and other weaponry.  No in-fill patterns are the same, and this is the key to tracking down a specific printer.

“3D printers are built to be the same. But there are slight variations in their hardware created during the manufacturing process that leads to unique, inevitable and unchangeable patterns in every object they print,” says Wenyao Xu, Ph.D., associate professor of computer science and engineering in UB’s School of Engineering and Applied Sciences and lead author of the study.

Senvol Developing Machine Learning for US Navy for Additive Manufacturing

Screen Shot 2018-10-22 at 12.15.26 AM

Senvol has publicly announced that it is developing data-driven machine learning AM software for the U.S. Navy’s Office of Naval Research (ONR). Senvol’s software analyzes the relationships between AM process parameters and material performance. ONR’s goal is to use Senvol’s software to assist in developing statistically substantiated material properties in hopes of reducing conventional material characterization and testing that is needed to develop design allowables.

Big Data to tackle Big Problems (Authentise Weekly News-In-Review – Week 06)

Hi and welcome to another edition of the News-In-Review, brought to you by Authentise!

The computational power at our disposal is increasing exponentially, being that of the phone in our pockets or the super-computer of the country next door. In our interconnected world, data is engulfing everything (as highlighted in our Week 3 edition). This week we propose how the two are coming together to address the great problems in our world, from national resource management to safer and more accurate than ever 3D printing. As IIoT is embedded in the national grid, it’s changing from a rigid, failure prone network to an efficient, system optimized in real time approach thanks to data-driven analytics. Processing that data requires new IT innovations, such as the first exascale super-computer now built in Chian. This, previously unattainable computational power allows us to simulate better 3D printing designs, materials and processes and can be used to unlock more AM use cases, such as construction.

As ever, there’s a lot to cover here. Let’s jump in!

Big Water – Big Data Is Reshaping The Water Industry

Data management, exploratory analytics, data visualization and predictive algorithms enable the discovery of important behavioral characteristics of highly‐complex urban infrastructure. Water management relies on heavy physical infrastructure and reactive administration. This changes with the development of cyber-physical systems, real-time monitoring, big data analysis and predictive machine learning algorithms and the IoT. These systems enable a transition from reacting to optimized, proactive and cost-efficient management processes.

World’s First Exascale Supercomputer to Enhance 3D Printing Capabilities

The Tianhe-2 Super Computer

China’s National Supercomputer Centre announced that the prototype for its exascale supercomputer will be completed later this year, ahead of its initial date in 2018. The successful performance and commercialization of the computer is presumed to drastically improve existing 3D printing or additive manufacturing methods. […] Through the usage of an exascale computing-based application, manufacturers will be able to use additive manufacturing technologies to better simulate end products and significantly optimize processes before the last stage of manufacturing.

Building by numbers: how 3D printing is shaking up the construction industry

Stewart Williams [admits] that quality control represents a major challenge [to the building industry]. To be viable, any printed building technique will have systems that can constantly monitor and inspect the materials as they are being produced. As he notes wryly: “You wouldn’t want to build a massive beam and get to the end and find you’ve got some holes in it.” Assuming regulators can be convinced, the potential upsides of 3D printing for the construction industry could be huge. Among the factors in the technology’s favor are productivity gains, reduced labor costs and safer working environments, as well as the sort of one-off, complex building designs that are not technically and economically feasible at present.
