Bhagat Singh is one of the ‘big names’ immortalised in the history of India’s freedom struggle and eternally cherished even after almost ninety years of his martyrdom. What makes him stand out is his popularity among the masses being almost on par with the likes of Mahatma Gandhi and Jawaharlal Nehru, despite his beliefs and actions being diametrically opposite to theirs.

Of the freedom fighters who remain mainstream in today’s India— a crowd predominantly made up of politicians with center or right of centre leanings, Bhagat Singh occupies a relatively lonely spot as a young, staunchly left-wing revolutionary who outrightly rejected Gandhi’s philosophy, and preferred direct action over politics.

Newspaper headline after Central Legislative Assembly non-lethal bombing

Bhagat Singh is most commonly and widely remembered in association with an incident where he, along with his friend and comrade B.K. Dutt dropped non-lethal smoke bombs into the Central Legislative Assembly from its balcony in 1929. They also scattered leaflets by the Hindustan Socialist Republican Association (HSRA), which he was a major part of and was aided by in orchestrating the bombings. He is said to have been inspired by French anarchist Auguste Vaillant, who had bombed the Chamber of Deputies in Paris in 1893.

The bombing gathered widespread negative reaction due to the use of violence, especially from those who supported the Gandhian method. While Bhagat Singh and the HSRA wanted to protest exploitative legislatures such as the Public Safety Act and the Trades Disputes Bill, it is also widely accepted that they additionally intended to use the drama and public attention of the ensuing trial to garner attention to socialist and communist causes. Bhagat Singh and Dutt did not escape under the cover of panic and smoke despite the former carrying a pistol, and waited for the police to find and arrest them. During the trial Bhagat Singh frequently chanted a variety of slogans, such as ‘Inquilab Zindabad,’ which is even today often raised in protests across India.

However, this was not the trial that ended in Bhagat Singh receiving his execution sentence. Before the Assembly bombings, Bhagat Singh had been involved in the shooting of police officer John Saunders, in connection to the death of freedom fighter Lala Lajpat Rai. At that time he and his associates had escaped, but after Bhagat Singh was awarded a life sentence for the Assembly bombing, a series of investigations led to his rearrest as part of the Saunders murder case. It was this trial— generally regarded as unjust— that led to his much protested execution sentence.

Bhagat Singh was hanged to death on the eve of March 23rd, 1931 and he was just twenty-three years old.

Despite the criticism he received for his actions, his execution sentence was widely opposed and many attempts were made to challenge it. In fact, his execution came on the eve of the Congress party’s annual convention, as protests against it worsened. He was memorialised nationwide as a martyr, and is often addressed with the honorific Shaheed-e-Azam Bhagat Singh.

Apart from being a socialist, Bhagat Singh was attracted to communist and anarchist causes as well. In ‘To Young Political Workers,’ his last testament before his death, he called for a “socialist order” and a reconstruction of society on a “new, i.e, Marxist basis.” He considered the government “a weapon in the hand of the ruling class”, which is reflected in his belief that Gandhian philosophy only meant the “replacement of one set of exploiters for another.” Additionally, he wrote a series of articles on anarchism, wanting to fight against mainstream miscontrusions of the word and explain his interest in anarchist ideology.

While writing the introduction to Bhagat Singh’s remarkable essay Why I am an Atheist in 1979, Late Bipan Chandra described the Marxist leaning of Bhagat Singh and his associates in the following way;

Bhagat Singh was not only one of India’s greatest freedom fighters and revolutionary socialists, but also one of its early Marxist thinkers and ideologues. Unfortunately, this last aspect is relatively unknown with the result that all sorts of reactionaries, obscurantists and communalists have been wrongly and dishonestly trying to utilise for their own politics and ideologies the name and fame of Bhagat Singh and his comrades such as Chandra Shekhar Azad.”

Bhagat Singh is often admired and celebrated for his dedication to the cause of liberation. However his socialist, communist and anarchist beliefs were suppressed by the successive governments in Independent India. This in a way is the suppression of a revolutionary who has the potential to inspire, unite and motivate the growing population of a spectrum of activists all over India, in direct response to the fast-spreading divisiveness and intolerance in the country, often patronised by the groups and organizations professing the right-wing fascist ideology.

Bhagat Singh’s dreams of a new social order live on, not just in his writings, but also reflected in the hearts of every activist, protester, and dissenting citizen. The fight for freedom, revolution, Inquilab, may have changed in meaning, but it is far from over.

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.
