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.

Constructing Panopticon: Israeli Surveillance Technology and its Implications for the Palestinians

Jeremy Bentham, an English philosopher and social theorist designed ‘Panopticon’ in the late 18th century. The panopticon is an institutional building which Bentham describes as “a new mode of obtaining power of mind over mind in a quantity hitherto without example”. The structure's central observation tower, placed within a circle of prison cells, allows a watchman to monitor the inmates of the building without the dwellers knowing whether or not they are being watched. Although it is physically impossible for a single watchman to observe all the occupants at once, the fact that the inmates cannot know when they are being watched means that they are motivated to act as though they are being watched at all times. Thus, compelling the inmates to regulate their own behaviour.

Michel Foucoault, a French Philosopher, uses panopticon as a metaphor to explore relations between systems of social control and people in a disciplinary situation. For Foucault, the real danger was not that the individuals are repressed by the social order but the fact that when only certain people or groups of people control knowledge, oppression is a possibility. Contemporary society uses technology for the deployment of panoptic structures ‘invisibly’ throughout society.

This article gives an overview of the massive panopticon that is built and operated by Israel in Occupied Palestine.

Israel’s unaccountable military rule over its Palestinian citizens in east Jeruselum, West Bank and Gaza Strip have kept the Palestinians under constant surveillance and control. As per a report by Amitai Ziv on Haaretz, Israel’s surveillance operation against Palestinians is (as of 2019) “among the largest of its kind in the world. It includes monitoring the media, social media and the population as a whole.”

Among various mechanisms of surveillance, the technological mechanisms of surveillance and control deployed or proposed in the region of Gaza Strip is most empowering to Israel in terms of gathering ‘intelligence’. This includes use of biometric identity cards, Israeli access to Palestinian census data, almost complete access to and control of the telecommunication infrastructure in the Gaza Strip, the ability to track individuals via cell phone, large surveillance zeppelins which monitor the entire electromagnetic spectrum and which can usurp control of these from Palestinian operators (for instance sending text messages to subscribers targeting different demographics) as well as optical surveillance, facial recognition technology, remote controlled and robotic machine gun towers guarding the border that are capable of identifying a target and opening fire automatically—without human intervention.

In the context of occupation, the use of biometric ID cards of Israeli citizens is the sharpest seepage of control technologies.  For a long time, Israel has used a system of differentiated ID cards to distinguish between Jewish and Non-Jewish, citizens and residents of Israel, and citizens and residents of the occupied territories.

These ID cards also have a record of ethnic/religious affiliation of the person, and the ID numbers themselves are coded so as to reflect this information. One’s status of whether they are an Israeli or Palestinian, whether they are a citizen or a resident determines their freedom to travel, their ability to find jobs, and even their ability to get married and avail social benefits.  The Palestinians in East Jerusalem—which was annexed after the 1967 war—are considered as “conditional residents” and not citizens. According to a Human Rights Watch report, a resident of Palestine occupied Israel reported that the Israeli authorities refused to issue birth certificates to his five children, all born in Jerusalem. Other Jerusalem residents without residency status, in their testimonials, described being unable to legally work; obtain social welfare benefits; attend weddings and funerals; or visit gravely ill relatives abroad, for fear Israeli authorities would refuse to allow them to return home.

Another significant technological mechanism is the Facial recognition technology which has found its way into use by Israeli police. Facial recognition system, a globally controversial and scientifically flawed system is being used by the police force in Israel to identify protestors and is also implemented at airports and border crossings.

Israel has also ratcheted its social media surveillance, especially Facebook, Palestinians’ preferred platform. In October 2015, Israeli invasion at the Al-Aqsa Mosque angered several Palestinians. Many teenagers who didn’t belong to military wing or the Palestinian political faction orchestrated the attacks. The Israeli government blamed the social media for instigating the attacks and the military intelligence increased the monitoring of Palestinian social media accounts. Consequently, over 800 Palestinians were arrested for their posts on social media, particularly Facebook. It was later revealed that these arrests were a result of a policing system which uses algorithms to build profiles of supposed Palestinian attackers. This system proctors thousands of Palestinian Facebook accounts sifting for words like shaheed (martyr), Zionist state, Al Quds (Jerusalem), or Al Aqsa. Further, the algorithm identifies a “suspect” based on ‘prediction’ of violence. These targets are marked suspicious and are a potential target for arrest on the grounds of “incitement to violence”. The term incitement refers to all types of resistance to Israeli practices. The Israeli Army declared Military order 1651 in 2010, according to which, anyone who “attempts, orally or otherwise, to influence public opinion in the West Bank area in a manner which may harm public peace or public order” or “publishes words of praise, sympathy or support for a hostile organization, its actions or objectives,” will serve a jail time of 10 years. The order defines this as “incitement”. One notable instance has been the poetry of Dareen Tatour. She is a Palestinian citizen of Israel. She expressed her call to “resist” the occupiers through a poem she posted online in October 2015. The video had less than 300 views. But it resulted in nearly three years of house arrest and five months imprisonment. The Israeli government charged Tatour with inciting violence and terrorism while her poem was a call for a non-violent resistance. This incident is a classic demonstration of how Israel uses vague terminology to criminalize online activity when it serves its discriminatory interests.  

Israel’s military industrial complex is a profound enabler of the digital surveillance of Palestinians. The nation not only implements surveillance and control but also manufactures and exports a massive amount of military and cyber security technologies. A report published by Privacy International—an NGO that investigates government surveillance and companies—in 2016—stated that Israel has about 27 surveillance companies which is the highest per capita in terms of surveillance that any country has in the world.

The Guardian collected testimonies from people who worked in the Israeli Intelligence Corps to understand the big brother surveillance of the Palestinians. One of the testimonies revealed that commoners and even completely innocent people were under the radar of surveillance. The attestor stated “As a soldier in Unit 8200, I collected information on people accused of either attacking Israelis, trying to attack Israelis, desiring to harm Israelis, and considering attacking Israelis. I also collected information on people who were completely innocent, and whose only crime was that they interested the Israeli security system for various reasons. For reasons they had absolutely no way of knowing. All Palestinians are exposed to non-stop monitoring without any legal protection. Junior soldiers can decide when someone is a target for the collection of information. There is no procedure in place to determine whether the violation of the individual’s rights is necessarily justifiable. The notion of rights for Palestinians does not exist at all. Not even as an idea to be disregarded.”

Another testimonial exposed that the data collected was hardly in accordance with the security needs. The testimony stated, “Throughout my service, I discovered that many Israeli initiatives within the Palestinian arena are directed at things that are not related to intelligence. I worked a lot on gathering information on political issues. Some could be seen as related to objectives that serve security needs, such as the suppression of Hamas institutions, while others could not. Some were political objectives that did not even fall within the Israeli consensus, such as strengthening Israel’s stance at the expense of the Palestinian position. Such objectives do not serve the security system but rather agendas of certain politicians. One project in particular, was shocking to many of us as we were exposed to it. The information was almost directly transferred to political players and not to other sections of the security system. This made it clear to me that we were dealing with information that was hardly connected to security needs. We knew the detailed medical conditions of some of our targets, and our goals developed around them. I’m not sure what was done with this information. I felt bad knowing each of their precise problems, and that we would talk and laugh about this information freely. Or, for instance, that we knew exactly who was cheating on their wife, with whom, and how often.”

While hidden and unknown surveillance is prominent, Israel has also imposed explicit panopticon surveillance and restrictions on Palestinians in numerous cases. In the village of Beit Ijza, northwest of Jerusalem, the house of Gharib’s family has been enclosed by a 6-meter-high fence, cutting them off from their olive gardens and rest of the village as Israel claimed ownership of the land surrounding the Gharib family's house and created a West Bank settlement over there. The house was built in 1979 on land the family says has belonged to them from as far back as the Ottoman era. “Ever since Israel occupied the West Bank, Jews have been offering my father to sell the house,” Gharib says. “They even brought him a suitcase of money. He refused.” Now, their every move is filmed as cameras have been set up on the bars of the fence. Along with loss of privacy, the panopticon internalized omniscience prevents the Gharib family from taking radical steps to protect their rights. In Israeli military language this is called an “indicative fence” which is also equipped with sensors.  When the fence was built, the family had to negotiate by phone with the police at the nearby Atarot industrial zone every time they wanted to go out and or they had to get the Red Cross to help out. “Sometimes we waited for several hours for them to come and open it” Gharib said.

Constant surveillance in real life as well as digital space is definitely a critical human rights violation. While the case of Palestinians is unique given the Israeli military occupation, the fight for their rights is global. World leaders, governments, civil societies, social media giants and all internet users have an essential role in the battle for a surveillance and censorship free state.
