India currently is the third worst-hit country globally in terms of the total number of COVID-19 cases which is still on the increasing trend. The country had imposed one of the toughest lockdowns across the world to counter the threat of Corona in the initial phase itself. Apart from the economic activities, the lockdown has impacted the education sector in a big way.

All the education institutions from pre-nursery schools to the professional colleges and universities were closed down in the month of March 2020 itself. These institutions are still closed for the physical presence of students and the classes are happening only through online modes which doesn't require students to venture out from their homes.

The schools and colleges cancelled the pending examinations of last academic year and gave general promotion to the students for the next class. Many examinations for admissions to various college programs in the country were also done away while some are still on.

Two of the biggest national level entrance exams, the NEET and the JEE, which have been postponed multiple times in the light of the increasing number of COVID-19 cases are now in the spotlight. This is due to the fact that the Ministry of Education recently stated that both the JEE and the NEET will be held in the upcoming month of September. The NTA has issued public notices citing that the JEE (Main) April 2020 is scheduled from September 1-6, while NEET-UG 2020 exam is scheduled for September 13.

The Supreme Court had responded to a plea filed on 17th August seeking postponement of the exams, while dismissing it, that the precious year of students “cannot be wasted”. The plea that had been filed through advocate Alakh Alok Shrivastava via 11 students from different states sought the quashing of the notices issued on July 3rd by the National Testing Agency (NTA), which set the dates for JEE and NEET in September next month.

The Medical Council of India (MCI) in response to the plea has submitted an affidavit to the Supreme Court stating that further postponement of the NEET would be a “drastic deviation” from the academic schedule which “may affect the subsequent academic years” of the students. It also ruled out the possibility of conducting NEET online owing to the “paper book format” of the exam. It further stated that conducting the exam at the same time everywhere is imperative and hence it cannot be organized in countries like Qatar and UAE which attract significant applicants.

With the centre looking adamant to organize the exams, student organizations like the National Students Union of India (NSUI), the student wing of the Indian National Congress, and the All India Student’ Association, student wing of the CPI(ML) have come together to protest against the decision. Both the outfits demanded cancellation of all first and second-year exams and giving promotion to the students, holding final year exams in a way such that students across the country can write them, and most importantly postponement of both the NEET and the JEE.

An argument in favour of conducting the exams as given by Education Minister Ramesh Pokhriyal Nishank was that the majority of the aspirants had already downloaded their admit cards for the exams. However, it is quite easy to see that students do not have a choice. One can argue that if we put ourselves in the applicant’s shoes, even we would do the same and download the admit cards. This by no means is an indication that students are willing to appear in the exams.

My personal experience in appearing for the JEE and AMU-EEE back in 2017 and 2018 is more than enough for convincing me in favour of postponing the exams. For JEE alone nearly 15 lakh students appear annually. The examination centres are usually overcrowded both before the beginning and after the culmination of the exam and it is nearly impossible to maintain social distancing. Also, the students are normally accompanied by parents or guardians which further adds up to the crowd. Further due to the large number of applicants it will be impossible to maintain distance in the examination halls unless and until the number of examination centres is increased tremendously. Due to various financial and logistical reasons, this will be an uphill task to accomplish.

Students across the country have reacted strongly to the decision of the Court on social media. Most of them are worried about contacting COVID which will put their own as well as the family members’ at risk. Manish Chaubey, one of the 11 petitioners in SC, said, “My hometown is in Gorakhpur in Uttar Pradesh and I am in Mumbai at present. It will be a hassle and immensely risky to travel now. Why should I have to put my parents through this?". While some pointed out the irony of the SC using a virtual mode to conduct hearings for making students appear in the exams, others chose to blame the BJP for being inhuman in forcing students into crowded examination centres.

In an open letter to the HRD ministry and education minister Dr Harshvardhan, MadhuPurnima Kishwar, founder of human rights organization, MANUSHI, sought to address the countless appeals regarding various issues and concerns of applicants nationwide received by her. Most of the appeals revolved around safety concerns and fear of contracting the coronavirus disease and thus jeopardizing the safety of family members.

In the letter, she pointed out how the recently organized KCET and B.Ed exam in UP were a clear indication of how it would be nearly impossible to implement the distancing and safety guidelines in the overcrowded examination centres. The overwhelming shortage of examination centres in the light of distancing norms was also mentioned in the letter. She also stated how many IIT and AIIMS directors were of the opinion that the exams could be conducted in November without significant academic loss.

Another very important fact mentioned in the letter was regarding the applicants from countries like the UAE and Qatar. Due to the mandatory 14-day quarantine period for anyone arriving in the country from overseas, it will be very tricky for these applicants and their parents to travel under the current scenario. Parents of nearly 4000 applicants in these countries abroad had filed a plea for either postponing the exams or conducting them abroad. However, the NTA, after consulting with the MCI, ruled that conducting the exams overseas is not a viable option which means that all these candidates will be left stranded. Even if they manage to fly to India for appearing in the exams, they will then be subject to various guidelines issued by their parent countries abroad.

Multiple politicians also voiced similar concerns regarding the decision. Congress leader Rahul Gandhi urged the government to consider the concerns of the students appearing for the entrance examinations. Manish Sisodia, Aam Aadmi Party leader and the deputy CM of Delhi also echoed similar thoughts. BJP leader Subramanian Swamy on Sunday came up with 13 points concerning logistical issues as well as safety concerns in the argument for the need of postponing the exams.

Another very strong argument in favour of postponing the exams was the lack of public transport services due to lockdown in many districts and states of the country. While those who had arrangements for private vehicles would not face any issue, the others would be left stranded in the absence of the various means of public transports. Lastly, many states are still under various degrees of lockdown as the overall situation of the country is still not very great in terms of daily coronavirus cases. This would also make movement for those applicants with examination centres away from their native places very difficult.

The debate surrounding the NEET and JEE exams has become quite a heated issue around the country. With so many applicants and their parents asking for the postponement of the exams due to various safety concerns, it remains to be seen if the government would still go ahead in organizing these exams as planned.

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.
