The civil war in Yemen, more so after 2015 has taken a toll on the civic infrastructure of the already fragile and poor country. Among these, the healthcare infrastructure of the country was one of the worst affected.

Apart from the physical damage to the hospitals and clinics due to the aerial bombings by the Saudi Arabia led coalition, the naval blockades exacerbated the dire situation. In June 2015 itself, aid agencies warned of the humanitarian risks brought by the US and UK-backed Saudi blockades.

The humanitarian situation aggravated further as there was a consistent famine since 2016 and Yemen was dependent on foreign aid for feeding almost 80% of its population.  According to UNICEF reports, over 3.3 million children and pregnant or lactating women suffer from acute malnutrition.

In 2017, the World Food Programme estimated that an additional 3.2 million people would be pushed into hunger. If left untreated, 150,000 malnourished children could die within the coming months.

Save the Children, the international charity and aid agency, estimated that 85,000 children under the age of five have starved to death in between 2015 to 2018.

Major healthcare operatives are dying due to the active bombing and conflict in Yemen, including personnel from MSF and United Nations Office for Coordination of Humanitarian Affairs (OCHO).

The MSF (or Doctors Without Borders), who have been in Yemen since 2007, have reported that fears of stigmatization are causing people to stay away from hospitals, with misinformation and lack of medical services only compounding the healthcare issue during the pandemic.

As of 24th July, the country reports 1640 confirmed infections and 458 related deaths.  Al Jazeera reported that “Cemeteries in Aden are overflowing with graves, suggesting that the number of people killed by the new coronavirus is higher than the official count.” Yemen and its related aid agencies also suffer from lack of PPEs and adequate information about the pandemic.

As of April 2020, there are 800,000 internally displaced persons in just one province of Yemen Marib. The number of verified civilian deaths stands at 7,700.

The United Nations has been continually asking for donations, but has failed to collect as much as it requires. While it collected $4 billion last year, it has only received $700 million, halfway into 2020.

The UN urged for $2.4 billion this year to fight the humanitarian crises and the Coronavirus. As of 2nd June, 29 countries and the European Commission pledged a total of $1.35 billion to support humanitarian efforts in Yemen, just over half of the amount needed to sustain programs through the end of this year.

In April 2020, the Saudi deputy defence minister, Prince Khalid bin Salman, said Saudi Arabia “will contribute $500m to the UN humanitarian relief program for Yemen in 2020, and an additional $25m to help combat the pandemic. It is up to Houthis to put the health and safety of the Yemeni people above all else.”

There are 41 major UN programmes in Yemen, and it is estimated that more than 30 of them will close due to lack of funds. The UN stated, “Due to the COVID-19 suppression measures, all integrated outreach activities, which include the Expanded Programme on Immunization, Integrated Management of Childhood Illness, Maternal and Newborn Health,and nutrition activities, were suspended.”

Most of Yemen's 3,500 medical facilities have been damaged or destroyed in air strikes, and only half are thought to be fully functioning. Officials warn that monetary relief may not be enough to assist in the war against the pandemic alongside the Civil War. A solution to the war must be found soon, before the pandemic eviscerates more of the healthcare infrastructure.

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.
