George Floyd’s recent death while in Police custody has sparked protests across the entire United States. While it did expose the way Black Americans are policed, it also initiated a much deeper conversation about the prevalent racism faced by Black Americans in almost all aspects of modern life.

Many symbols of the racist past still exist across the US, more so in the Southern states. The recent trigger of protests and the BLM movement has initiated a discussion about these symbols once again. While some argue that it is important to preserve these symbols owing to the American culture, the majority of the people seem to be agreeing that these are symbols of oppression and injustice.

In the mid to late 19th century, white actors quite commonly employed the use of black grease paint to depict slaves and free blacks on stage. The technique commonly known as blackface was more than just facial makeup. Rather, it was used as a symbol for mocking the African-Americans as inferiors in every aspect of life.

Blackface seemed to have disappeared in the 1960s thanks to the Civil Rights Movement. It however reappeared in the 1980s on college campuses in the wake of steps taken to bring more African Americans to campus. An old yearbook picture from Langley School resurfaced recently revealing the then-principal and vice-principal dressed as whiteface and blackface for Halloween. The current leadership of the school have issued apologies stating that the incident should not have happened.

Despite a racist history surrounding blackface, a recent survey by Pew Research Centre revealed that nearly one-third of Americans surveyed did not find anything offensive in blackface being used at Halloween.

Aunt Jemima, a 130-year-old syrup and pancake mix brand owned by Quaker Oats depicts a black woman named Aunt Jemima who was originally dressed as a minstrel character. The company has earlier made tweaks to the picture of the black woman in response to the criticism it received for propagating a racial stereotype. In June 2020, Quaker Oats announced that the brand would be rejuvenated to feature a new name and image.

Andrew Jackson, the seventh US president and his family employed hundreds of enslaved people in building their wealth. However, to date, Jackson still haunts Black Americans with his presence on the twenty-dollar bills in the wallets of these Americans. The Trump administration’s decision to not replace the bill featuring Jackson with one that would feature abolitionist Harriet Tubman as proposed earlier does not help the nation’s troubled history with Racism.

Similar symbols of the US racist past exist across the entire country, starting from streets named after Confederate officers to congested highways specifically designed to ensure isolation of Black neighborhoods. Football and baseball games in the country still feature the national anthem penned by Francis Scott Key, a person who used his power as district attorney to prosecute Black men.

George Floyd’s death was the perfect trigger for all the anger and frustration against the systematic injustice that has been meted out to Black people. However, it also served well to initiate debates over the omnipresence of these racial symbols across the country that serve as memorials to slavery and white supremacy.

As many as 800 Confederate statues and monuments have been removed ever since the BLM protests erupted in the country. A few of these racial symbols in the US suffered the brunt of BLM protesters who defaced homages and toppled statues of founding fathers who had profited from slavery.

Those against the removal of these symbols argue that these men merely failed in morality due to the socio-political environment they inhabited. Alvita Akiboh, an assistant professor of history at the University of Michigan, however, disagrees with the notion. “Just because slavery was accepted among white elites or even the broader white population at the time does not mean it was accepted by everybody, because everybody includes Black people who were enslaved, indigenous people who were pushed off their lands in order to expand plantation slavery,” said Akiboh.

Others, including US President Donald Trump, have employed the notion of removing these symbols as the equivalent of “ripping American history and culture apart”. To this Akiboh voices her opinion saying that the majority of these symbols were erected decades after the civil-war conflict ended. She argues that they are merely “a reminder for Black and brown people to remember their place”.

As the BLM protests gain momentum and support globally the scrutiny of the racist symbols in the US shall increase manifold. With the government not willing to push for major reforms and removal of these racist symbols and an adamant public demanding an end to the systematic discrimination based on race, the road ahead for the recial relation in the US is a difficult and complicated one.

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.
