3D Printing in India: A Step towards Innovation
2018-01-29

Dr. Sathish Vasishtha and Dr. Derick Mendonca from a hospital in Bangalore used a 3D printed model to plan a surgical procedure to treat ‘Orbital Hypertelorism’. A disorder caused by the abnormal development of the bones in the forehead during infancy stage leading to causing an abnormal distance between the eyes.

In order to correct this condition, they created a 3D printed model of the patient’s skull (to remove the bone in the midline skull) which helped the surgeons to visualize results in the operation.

Such kind of model allows the surgical team to practice the procedure before the operation thus they can be able to reduce the risk of any possible mistake or infection in the on-going operation.

The above story tells a tale which would not have been possible just some years back. All the credit goes to 3D Printing.

What is 3D Printing?

3D printing, since the time it was first implemented, has been developing in such a way that it buckles every aspect of conventional product manufacturing. The underlying principles of 3D printing and the printers are. Ever since moving towards a unified state of turn-key manufacturing limited by our imagination.

3D Printing in India: A Step towards InnovationSince the 1980s, when it was first implemented, it has been called “the overnight revolution decades in the making”. But the progress that has been made in the last decade has overshadowed much of the dream. It has found its appeal in the hands of individuals, who personify its potential through early adoption and experimentation, instead of being an industry changing technology.

3D printers deposit materials layer by layer and thus fabricate the complex objects. The most common household 3D printing process involves a “print head” that allows for any material to be extruded or squirted through a nozzle. A user selects an electronic design blueprint and loads the raw materials into the 3D printer. The machine does the rest.

Using computer-aided design data, it prints a solid 3D object. There are several other processes such as selective laser sintering, fused deposition modeling, etc. that differ in the way layers are deposited to create 3D objects.

According to a 2013 report, India has seen a transformation in the 3D printing industry with the emergence of local 3D printer manufacturers.

3D printers makers say that the 3D printer market in nascent in India. They also provide 3D printing services and DIY kits that can be merged with imported products and labeled “made in India”. The printers are mostly used by smaller companies to “verify industrial designs and not for mass production”.

The scenario is quickly changing though

According to a study by 6Wresearch, with automotive applications, the 3D printer market in India is expected to cross $79 million by 2021. Educational and medical applications are also expected to grow to a huge extent.

Due to increasing use of rapid prototyping and 3D modeling across various industry sectors, India accounts for major potential growth for domestic manufacturers, local assemblers, and distributors. The 3D printing machines are primarily imported to the country from China, USA, and Germany. However many more local players are expected to emerge in this period to boost domestic manufacturing like the “Make in Campaign”.

The report also divides the market into different applications i.e. Electronics and Consumer Goods, Automotive, Medical, Industrial, Aerospace & Military, Educational, Architectural & others and end users including private, commercial and industrial.

Some market applications of 3D printing technology

Architecture:

3D printing has transformed the architectural industry by enabling the architects to create and visualize precise design models, which facilitates quick design approval and faster consumer input.

Engineering and Electronics:

3D printers are empowering engineers in India, hence leading the digital revolution, to witness their innovations much quicker than before. The manufacturing processes have started becoming more personalized and agile due to this technology. This technology has made it possible to manufacture production tools on the fly or create a specific number of production parts.

Dental Technology:

In this field, 3D printing technology is now being used in India for a wide portfolio of orthodontic applications. CAD-based dental parts have substantially reduced the material and labor costs of dental restorations while maintaining superior clinical quality. This economical and productive technology has assured a level-playing field among the global players in the dental world.

Jewellery Business:

The traditional jewelry making is ripe for disruption in India. 3D printers are making their presence felt in the Indian jewelry business by cutting the time to make pieces, one of the biggest requirements while selling online. In addition to this, with no physical interaction, 3D renderings serve as a much better way to show customers of designs they’re getting commissioned.

Aerospace:

3D printing major EOS and Wipro’s advanced manufacturing division have built India’s first Additive Manufacturing (AM) engineered component for ISRO, the North-West feed cluster 2x2. This component was a part of the GSAT19 communications satellite for India.

"The additive manufacturing industry in India is on a positive path with scope for huge growth in the future. However, no opportunity comes free of cost. India, being a price sensitive nation, is an evolving stage and yet to see the rapid adoption rate. With consumers following conventional approach, modeling in India is still done through CNC machines which cost less than 3D printers. Thus the players feel a sense of reluctance to go for 3D machines. In order to increase the penetration, it requires major transformation such as easier design capabilities, compatibility for mass production and manufacturing of large format objects."
