The civil rights movement in America labelled “Black Lives Matter”, which erupted after the murder of George Floyd by a uniformed officer has been going in full swing. The event of Floyd’s death triggered a mass reaction against the state violence in which black people are abused without any accountability on the police’s part. A few of the protests have been demanding the defunding of the police department, that the police force should be dissolved.

Many protests are peaceful protests, but there have been instances in which the protestors use violence to express their sentiment. Such protests have received a lot of backlash; Donald Trump, the president, said that “these THUGS are dishonouring the memory of George Floyd” and that “when the looting starts, the shooting starts”. He also mentioned that he would send the National Guard to “get the job done right”, in context of his perceived lack of leadership in Minneapolis where Floyd was killed, and consequently, where the protests were taking place. The tweet with the slogan “When the looting starts, the shooting starts” has since been censored by twitter, which gave birth to another controversy.

Trump also blames the riots on Antifa, which is a terrorist organisation according to him, the name of which stands as a short form of anti-fascist. The organisation is a group of leftist activists who protest against an expression of what they find xenophobic, racist or sexist and fascist, claiming that such expression would suppress minority voices. There is no defined hierarchy or membership process, though it has been claimed by the group that it is secretive and is organised into autonomous local cells. In some reports, though, it is categorised as a far left militant organisation which believes in direct action rather than peaceful protests.

The police force in Minnesota believes that there are white supremacists attending the protests to agitate the protests and incite chaos. The Brookings Institution characterized the same as accelerationism, in which people incite chaos to destroy social order, so that in a highly polarized society, people would take their side. In the same vein, it has been reported that a white supremacist channel on Telegram incited followers to engage in violence and start a second civil war by shooting into the crowd. Franklin Graham, an evangelical pastor, has said that the idea of dismantling the police departments “has to be one of the most irresponsible ideas” that he’s ever heard. He says that the police are what stand between “us (the citizens) and total anarchy”.

An UK Member of Parliament told one of his constituents that while racism is a cancer, and I am glad the perpetrator is on a murder charge. Nevertheless, looters, arsonists and rioters have it coming.” While a number of celebrities have been showing support for the Black Lives Matter protests, the former Miss Universe Malaysia Samantha Katie James used instagram stories to say that the protesters who are angry over the murder of George Floyd are “foolish humans”, and that the black people chose to be born as colored people in America. She also said that the brutality should be taken as a challenge and that “the whites have won”. When asked to clarify what she meant by saying that the Black community chose to be born as coloured, she said that their soul chose where and how they were born.

The people are responding in many different ways to the news. On a Brietbart report on Samuel L. Jackson expressing his views in support of the protests, there have been comments which say that “Floyd was a criminal and he was high on drugs and that he was not killed by asphyxiation he had a heart condition.”(sic) or “When da White people start rioting? We are still the majority, and it would really stir up the fudge. These a****ts think they are getting away with something, but only because the silent majority has yet to speak… and act.” (sic).

It seems that George Floyd’s unfortunate death has brought out not just the simmering anger of the long black community in open but also unmasked the outright white supremacists as well as their apologists.

3D Printing: The direction to go for the Indian Defense and Aerospace Industries

3D printing is the next big game-changer on the technological front, almost a revolution if you will. 3D printing, also known as additive manufacturing, is a process of creating three-dimensional objects by layering two-dimensional cross sections on top of one another. The two-dimensional cross sections are computer-designed and rendered, which makes it all the more advanced. From Aerospace to Defense and Medical to Automotive, products manufactured via 3D printing are spreading their reach in the markets quite swiftly. This article will take a look at how 3D printing is beneficial and how the technology can transform the Indian and Defense and Aerospace sectors once utilized to its full potential.

Additive manufacturing has the power to unlock a wide range of opportunities. It uses a 3D printer to create a layer-by-layer “addition” of material which is digitally constructed. Different types of materials which are currently being used for the same are metals, ceramics, special plastics, synthetic resins, and etc. 3D printing not only reduces the cost of production of various components but also gives the power to manufacture locally with design flexibility. The technology significantly speeds the process of designing; this is mainly because there is no requirement of tools. Traditional manufacturing usually takes months to either acquire necessary tools and further produce parts and components or import components from various places. However, once 3D printers are acquired, which they might be costly in themselves, they would ensure a smoother production process. Hence, due to the combination of localized manufacturing and no tools, tailor-made designs can be produced to match the necessities of various industries.

India is gradually growing with respect to its utilization of 3D printing technology. In 2014, the 3D printers market was at an early stage with just 200-500 combined workforce of engineers, designers and sales representatives. Currently, start-ups are springing up in places like Bangalore, Chennai, Mumbai, Visakhapatnam, etc and they are producing essential parts for sectors like the Indian Navy, Air Force, ISRO and the HAL.  India’s 3D printing market is projected to reach $79 million by the end of 2021, while the global market is at around $15.8 billion, which suggests that India has a lot of catching up to do.

Applications in the Aerospace and Defense Industry

The Aerospace and Defense Industries are keen to pursue additive manufacturing, mainly because of benefits such as weight reduction, cost cutting and to meet their highly specific requirements. The additive process uses less material to manufacture components and also ensures minimal waste of material. Overall reduced weightage means that less fuel would be used in aircrafts and hence result in better environmental compatibility. Let’s examine a few instances in India where 3D printing startups have assisted and provided the defense and aerospace sectors with unique solutions.

Recently, in 2020, the Centre-run defense company Hindustan Aeronautics Limited (HAL) had signed a MoU (Memorandum of Understanding) with Wipro 3D, the metal additive manufacturing branch of Wipro Infrastructure Engineering. The initiative would primarily focus on the design, development, testing, manufacturing, and repairing of aerospace components using metal additive technology. HAL is using 3D printing to manufacture engine components, although it also provides support to helicopter and rotary wing products. HAL also provides products to the Indian Army, Air Force, Navy, and Coast Guard. Speaking about this collaboration, Shekhar Shrivastava, CEO of the Bangalore division of HAL, said, “This initiative between HAL and Wipro 3D will create a unique synergy of capabilities that can accelerate the adoption of metal additive manufacturing in aerospace in India. Qualification of parts for aerospace is challenging as it would require prove out and extensive testing followed by certification by regulatory authorities which may also include flight testing."

Down south, Karnataka, which produces more than 65 percent of India’s aerospace-related components and exports, has taken a number of initiatives to promote additive manufacturing by setting up 3D printing clusters and sponsoring 3D printing startups. For example, through its flagship programme ‘Start Up Karnataka’, the State has given grants to ‘Deltasys E-Forming’, a Belgaum based start-up, to develop hybrid composite 3D printers. These initiatives are quite appropriate since two-thirds of India’s aircraft and helicopter manufacturing for the defense takes place in Karnataka, and 3D printing would revolutionize these processes quite rapidly.

On the other coast, Chennai-based 3D printing startup, Fabheads Automation, was established in 2015 by an ISRO engineer turned entrepreneur Dhinesh Kanagaraj. The deep tech startup designs and develops high-end carbon fibre helicopter blades for the Indian Air Force. Traditionally, carbon fibre parts are fabricated by laborious manual processes with a lot of fabrication time and money spent. Dhinesh also observed a lot of material wastage when he worked on carbon fibres at ISRO.  Based on this, Fabheads has designed an automated 3D printer series to eliminate material waste and also improve efficiency of production of carbon fibre. Sectors like the DRDO are currently approaching the company given these innovative methods of production.

3D Printing Saves the Day for the Indian Navy

Further, the Indian Navy has partnered with ‘think3D’, a Hyderabad-based 3D printing start-up, to produce spare components via additive manufacturing for both on and off-shore set-ups. The Indian Navy uses a lot of machinery on its ships which are imported from other countries and are quite old.  Whenever a component gets damaged, it is hard to replace it either because there is no availability of the part or because there is significant delay before a part is received. This often proved to be costly for the Navy since the machines would have to be kept idle before a spare part was replaced along with the fact that procurement of the parts was no less expensive.

This is where think3D had stepped in and supplied 3D printed parts to the Indian Navy, which were successfully tested and incorporated into its machinery. An example of such a 3D printed part, which proved to be of crucial help, is that of a centrifugal pump impeller- a key component for a ship’s operation.

The impeller is a rotating component and it is very important for a ship as it transfers energy from the motor to a fluid that needs to be pumped by accelerating the fluid outwards from the centre of rotation.  On ships, this component is used to import seawater into various parts of the ship for regular use of the crew. These impellers are required to rotate at high speeds for long durations and need to be very carefully designed. 3D printing was the best solution to replace these parts, given the speed of production and lower expenses.

Given all the benefits of 3D printing, it is high time for the Indian market to expand its 3D printing industry and utilize it to its full potential. There are many other instances like the one of the impeller in the Aerospace and Defense industries which can easily be solved using 3D printing.
