The past few months have seen an unprecedented uprising against Israeli Prime Minister Benjamin Netanyahu, owing to rapidly rising unemployment rates and mismanagement of the COVID-19 crisis. Protestors have been gathering at Netanyahu’s residences and demanding that he resign.

Many claim that while the government was initially able to control the spread of the coronavirus, it was too quick to reopen the economy, which led to a more devastating second wave of cases and ended up only hurting small businesses and employment even more. The crashing down of the economy and public healthcare system is touted as evidence of a selfish government which is too distant from the interests of its citizens.

Additionally, Netanyahu is facing trial for charges of corruption. Though the charges first began to surface back in 2016, the indictment came last November. On top of that, it is being alleged that Netanyahu is trying to leverage the pandemic to delay court hearings. In light of the corruption charges, calling Netanyahu “Crime Minister” has emerged as a popular slogan at the protests.

The protests seem to be mostly organised and led by Israeli leftists, who hold up black flags representing their anti-Netanyahu, anti-corruption and pro-democracy stance. Some protestors have also taken to dressing up in space-themed costumes, in response to a comment by Netanyahu’s son calling the protestor’s “aliens.”

The biggests protests are those held regularly outside Netanyahu’s official residence in Jerusalem and his private home in the high-profile neighbourhood of Caesarea. The police presence at the protests has been heavy; clashes and arrests are common. Small international protests in support of the ones in Israel have been organised in the United States and Britain.

The protests usually bring a mixed crowd of those protesting corruption charges and business In terms of demographics, some have noted that religious Israelis and Israeli Arabs have been a minority presence in the protests, perhaps the former due to political leanings and the latter due to marginalisation and disenfranchisement. At the same time, the protests are being admired for bringing together citizens across political lines, religious beliefs, and ages, as well as the sight of many families attending protests together.

The supposed political leanings of the majority of the protestors is the key argument Netanyahu has given while dismissing them, calling them “anarchists,” while also reportedly accusing local media of giving them more coverage than they deserve. He has also denied the allegations of corruption levelled against him.

There have been many reports of counter-protests by right-wing groups, often alongside the anti-Netanyahu ones. Supporters of Netanyahu, attempted to ram a car into a protest, called protestors “germs”,  pepper sprayed and attacked them with bottles and clubs. For now, the courts seem to be protecting the Israelis’ rights to freedom of speech and to protest from appeals to curtail the protests in any manner.

There is speculation regarding whether resignation is the “right” demand, since it seems unlikely that someone like Netanyahu will ever follow through on that. But the people of Israel are out in the streets in the thousands. They are called aliens or anarchists all day but denial is a facade that can only last for so long.

Netanyahu is now the longest serving prime minister of Israel. He started the new term when his right-wing Likud party signed a coalition deal with Benny Gantz led Blue and White Party which provisioned 18 month long terms for both of them. Gantz’s term is to begin from November 2021 and some analysts predict that Netanyahu might hold early elections to deny prime ministership to Gantz and in the process, delay Israel’s next budget.

The biggest ally of Netanyahu so far in his political career was his luck which finally seems to desert him. He might be thinking that the protests can be waited out and accountability can be avoided. However this time, his political instinct and survival skill may come up short in the face of determined opposition from the common citizens of Israel.

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.
