With over 1.2 million active cases and over 51 thousand deaths as on 30th June 2020, Brazil is one of the worst coronavirus affected countries. Latin America became the epicentre of the coronavirus pandemic in the latter half of May, largely due to Brazil’s incompetency in dealing with the pandemic. Due to the underreporting and low testing rates, the actual number of active cases and deaths are unknown.

The Brazilian Ministry started making changes to the number of cases reported, making it even harder to control the situation the pandemic has caused. The country’s response has been widely criticized in Brazil and outside. The President of Brazil, Jair Bolsonaro, dismissed the threat of the virus and the pandemic. OnMarch 26, 2020, he said that Brazilians are immune to the virus and even if they are drunk in a sewer they “don’t catch a thing.” He defied the guidelines set by his own health ministry and visited a busy commercial district in Brasilia, the capital of Brazil, where he told all the elderly Brazilians to get back to work. He also went on TV many times and called it little flu and accused the media of hysteria. Even as the coronavirus crisis has worsened recently, some major cities have eased their preventive measures, like Sao Paulo opening up shopping malls in Mid-June and beaches getting crowded again. With all of this happening, hospitals are close to running out of intensive care beds.

In early March, Brazil declared a public health emergency, a few days after the World Health Organization. The Ministry of Health in Brazil urged the officials to cancel all the public events and reinforce the measures of social distancing as prescribed by the World Health Organization. Some experts thought that Brazil could handle the pandemic based on its records during past public health emergencies. Brazil’s health care system is underfunded, but it does not fail to provide robust coverage across the country. The efforts of the state government went awry when the President called the virus a “cold” and provided anti-malaria tablets as a solution to the virus. President Bolsonaro’s clash with the governors and officials led to two health ministers leaving- one was fired and the other one quit. This left the military general, with no public health training, in charge of the virus. The clash amongst the government left the citizens of Brazil uncertain about the importance of following the preventive measures kept in place to prevent the spread of the virus. This led to the defying of the measures, which in turn led to the pandemic’s rate being one of the highest in the world.

The Ministry of Health has not presented a comprehensive plan to beat the virus yet. One of the main initiatives by the Ministry of Health is to boost the production of hydroxychloroquine and has encouraged the doctors in the public healthcare system to prescribe the same. The country has struggled to import lifesaving instruments, like coronavirus tests and ventilators. The lack of tests, in turn, has made it difficult to track the spread of the virus. This might result in the undercount of cases of the virus in the country.  Between Jan. 1 and June 6, 23,171 people who were not diagnosed with the coronavirus died from acute respiratory infections, according to data released by Fiocruz, one of Brazil’s state-run health research institutes. Experts believe most of them died from coronavirus.

At a time when Brazil needs to be putting all its efforts into fighting the virus, the president has been wrapped up in his own political battles. The Supreme Court is investigating allegations of disinformation and intimidation by the President’s supporters. Investigations also state that he has interfered in federal police investigations to protect his family. Due to this, the tensions between President Bolsonaro and the judiciary are high.

During the past few months, politics have become bigger than the pandemic. Even though the health crisis is extremely important, the magnitude of the political scandals has had a huge impact on how the country reacts to the pandemic. There is anger over how President Bolsonaro is handling the crisis and at the same time, there is a fear as to where the country is headed after the pandemic passes.

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.
