JSW Metal is constructing a captive energy plant at Salem. The commercial steam turbine being arrange wanted oil sealing rings, a seemingly small element however a vital one for the operating of the unit. JSW Group’s procurement workforce made inquiries from their ordinary suppliers and had been advised that in a greatest case situation, they may manufacture the oil sealing rings in Four-6 months.

This was a typical scenario confronted typically by the trade the place delay in sourcing of a small parts typically result in derailing commissioning timeline. However one thing completely different occurred this time. “We had been taking a look at choices to compress time and Siemens supplied to make the identical element for us by means of 3D printing,” stated Seshagiri Rao, joint managing director at JSW Metal. “We advised them to do it and so they delivered it in a matter of days. We tried it as an experiment and we had been profitable,” he advised ET.

3D printing, or additive manufacturing — the method of constructing three-dimensional strong objects from a digital design utilizing additive strategies — has but to select up within the nation however consultants see important potential. “The marketplace for 3D printing in trade is latent and is tough to outline. It’s not a market the place the product is prepared for business functions; it’s just about within the growth stage,” stated Prashant Jain, nation division lead – energy technology providers division, at Siemens India.

3D printing makes slow but steady inroads into industry

“Proper now, the expertise is used extra for creating pilots however going ahead an increasing number of elements might be printed for machineries in crops; even these that are out of date and the shopper is on the lookout for parts to interchange them,” he stated. Market analysis firm 6Wresearch has projected Indian 3D printer market to be value $79 million, or about Rs 535 crore, by 2021, pushed by home manufacturing, low price of producing, and growing penetration throughout varied purposes, together with ‘Make-in-India’ initiative.

The worldwide marketplace for 3D printing is seen rising to $20 billion by 2020, which can nonetheless be solely a fraction of the complete tooling market on the time. International consultants McKinsey believes the general financial impression created by additive manufacturing (AM) may very well be a lot greater, reaching $100 billion to $250 billion by 2025, if adoption throughout industries continues at right this moment’s price. Most of that potential will come from the aerospace and defence, automotive, medical, and client items industries.

THE TECHNOLOGY
3D printing, or additive manufacturing (AM), may very well be a sport changer. The expertise “prints” or assembles a 3 dimens

“Right now, the technology is used more for developing pilots but going forward more and more parts will be printed for machineries in plants."

ional object layer by layer, the place every layer is sort of a thinly sliced horizontal cross-section of the article being made. An power supply like laser or electron beam is used with supplies reminiscent of steel, polymer or resin in a regulated setting to transform a 3D design into object, one micro layer at a time.

The normal strategies of producing are primarily based on subtractive manufacturing, which entails chopping out and hollowing out a bit of steel or polymer, and are, due to this fact, restricted by the instruments obtainable, whereas a 3D printer has the flexibleness of producing a number of sorts of designs.

“AM can be utilized for mass customisation; for example, a buyer would have the ability to purchase sneakers which might be excellent match and customised for him and never only a greatest match,” stated Ajay Parikh, enterprise head at Wipro3D. “The expertise additionally provides flexibility and skill to make complicated geometry that permits designer to maintain experimenting with designs.

At the moment, if you’re making jet engine parts for a corporation, you don’t need to decide to a design as the one choice. The liberty and velocity in AM will help alter the design within the subsequent engine, and you’ll give you functionally higher designs,” he stated. Wipro3D focuses on metal-based AM.

BIG BOYS VS STARTUPS
Expertise majors reminiscent of Siemens, Wipro and HP Inc, amongst others, have noticed the chance on this house in India. HP launched its 3D printing options within the nation earlier this 12 months, nearly a 12 months after its worldwide foray, and is eyeing collaborations with the federal government to develop the scope of enterprise.

Wipro3D launched its state-of-the-art resolution and expertise centre for steel 3D printing in Bengaluru in March. Startups, too, have entered the market, primarily by providing 3D printing providers reminiscent of designing, prototyping and different associated providers, typically collaborating with some greater gamers. These corporations are catering to a number of industries like healthcare, jewelry, automotive and client merchandise.

ROAD AHEAD
Challenges are largely the identical for giant corporations and startups. “We began our firm in 2013 and being one of many first firm to even discuss this expertise, we thought that in 5 years we may very well be promoting few hundred thousand machines,” stated Arvind Nadig, cofounder of Brahma3, which launched the nation’s first regionally made 3D printer. “However the consciousness out there is basically low. It’s not simple to arrange in India as a result of investments usually are not coming by as volumes are nonetheless low,” he stated. Nonetheless, regardless of the challenges, Nadig is bullish as there may be good traction from defence and training sectors.

All of the sector executives ET spoke to stated they’ve to take a position a variety of effort and time to persuade potential prospects in regards to the reliability of the expertise, power of the product, and the general monetary profit — even when the product price is greater, the supply time is shorter. JSW is impressed with the expertise as a buyer. “We at the moment are taking a look at this expertise critically,” stated Rao who can also be the group chief monetary officer at JSW Group. “We’re planning to verify with suppliers on the time of inserting the order for equipment itself whether it is attainable to make use of 3D printing for some parts which may give a financial savings in time,” he stated.
