The Israel-Palestine conflict is one that has been fraught with violence and displacement, more so for the Palestinians. This is a complicated history of war and disagreement over the possible solutions. However in recent years, the actions of Israel’s right-wing coalition government under Prime Minister Benjamin Netanyahu are making the path to peace even more difficult.

Many artists, especially those of Palestinian origin, across the creative mediums, have turned to art as a medium of expression against the Israeli government’s repressive policies and to show the suffering of the Palestinian people.

The heroes of Palestinian resistance against the Israeli occupation are a popular subject of resistance art by Palestinian artists. It is mainly expressed in the form of murals, graffities, and posters.

Another important theme in Palestinian art surrounds the Nakba, which refers to the exodus of a large number of Palestinians after the formation of the state of Israel.

A popular street artist Banksy has left his unique mark in support of Palestinian resistance, and not just in the form of street art which lines the Israeli West Bank barrier and other areas of the West Bank.

Banksy also opened the Walled Off Hotel in 2014 where all the rooms overlook the barrier or apartheid wall, as it is known in Palestine, and each contains various artworks depicting life under occupation.

The most recent contribution from Banksy in this regard has been a small art piece that was displayed inside the hotel last Christmas, called ‘The Scar of Bethlehem.’ It depicts a nativity scene (the birth of Jesus) set to the backdrop of the concrete barrier, with a bullet hole in it resembling a star and has garnered praise from many western news outlets as a symbol of solidarity with Palestinian suffering.

Posters, and innovative methods of distributing the same, are another form of artistic protest. These range from the posters by various artists published in a leftist French newspaper, meant to be cut out and pasted on walls by the public; to the Turkish graphic design professors using public walkways to exhibit posters in solidarity with Gaza.

Posters have also sprung up in various places across the world, including Israel, calling for active demonstrations against Israel’s plans to annex the West Bank. All of the mentioned posters continue to be collected in the digital archives of the Palestine Poster Project.

Another popular collection dates back to 1970s Australia, circulated by Ali Kazak, a Palestinian ambassador, called “landscape posters” for their focus on Palestinian land. Many posters utilised symbols such as traditional Palestinian dresses, fruits such as olives and oranges, and keys, which refer to the refugees.

Some of the older art from around the 1970s focused on pre-war Palestinian life and culture, while the newer art takes a multi-media form through photographs, science fiction and films. Similarly, many murals can be found surrounding Land Day, which serves as a reminder of a massacre in 1976 in response to a protest.

Artistic symbolism also often uses the concept of Sumud, which means resilience in Arabic, and is used to refer to a “sense of rootedness” to Palestinian land.

Music also found its voice as a form of self-expression and resistance. In 2018, music platform Boiler Room hosted Boiler Room Palestine for the first time. The show featured a diversity of Palestinian artists from Palestinian and Israeli territories. The crew for the show had to enter Palestine through Israel, giving them a small taste of the limitation of movement for Palestinians.

Palestinian art continues to grow as a form of self-expression, as a form of resistance to Israeli policies, and as forms of cultural history in an endeavour to keep Palestinian spirits and identity alive as their lives get shrunk into smaller and smaller pieces of land.

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.
