Interview with Arpit Sahu (Director), Objectify Technologies India – A Leader in Additive Manufacturing Services

The Additive Manufacturing in India has just begun its foothold and now it’s time for it to proliferate. Indian manufacturing industry is in process of shift from conventional to modern technologies according Arpit Sahu. He talks to DailyCADCAM about using CAD, CAE tools to optimize product before it is printed, adoption of AM in India, more. 

 

About: Arpit Sahu (Director), Objectify Technologies Pvt Ltd. 

ArpitSahu

 

He has pursued his Master of Science (5 year Integrated), 2013 in PHYSICS from Indian Institute of Technology, Kanpur. He founded Objectify Technologies right after graduating from college in 2013, at SIIC Incubation Centre at IIT Kanpur itself. He currently has around 4 years of experience in 3D printing / AM sector, during which Objectify Technologies has grown leaps and bound from an experimental desktop 3D printing start up to an established name in AM industry in India.

 

 

 

 

Please give us a brief information about your services and infrastructure?

I started Objectify Technologies along with my brother Ankit Sahu in IIT Kanpur incubation center with an aim to provide best-in-class additive manufacturing solutions to the Indian manufacturing community.
In just 6 years of operation, we have become India’s one of the leading Engineering Organization with expertise in Additive Manufacturing(metal and polymer) and Vacuum Casting. With specialization  in  providing  high-quality   technological  solutions  in industries such as Aerospace,  Automotive, Tooling, Medical, FMCG, among others; We  provide  integrated metal  and  polymer additive manufacturing and have received ISO 9001:2015 certification from TUV Nord.
We are an engineering driven company and believes in investing in the right technology and talent. We have about 70 people in our team and most of them are working in engineering departments. When it comes to infrastructure, we have EOS metal and polymer printing machine, CNC machines from MAZAK and BFW, Hexagone CMM for quality check and also have software from companies such as Autodesk for design, printing and simulation activities.

 

What role CAD Software play in Additive Manufacturing? 

CAD Software is a key ingredient to the whole additive manufacturing process. It’s one of the pillars in which Additive Manufacturing stands in. With the constant innovation in Additive Manufacturing/3D Printing to help it make faster, better and cheaper parts we must not forget the equally important contribution by CAD application. It’s obvious that Design and Simulation saves time and money, but contradictory to popular believes of their flawlessness is a lie. They do need upgradation like the technology itself and yes they have been updating rapidly. We have seen a lot of success in Rhino & SOLIDWORKS. Without them it wouldn’t have been possible to give partners an efficient timeline.

When is a 3D Printed product defective? Do you use any CAE (Analysis Software) to optimize product before it is printed?

The designs received from our partners go through rigorous testing through our simulation applications. Sometimes the dimensional issues are at question and other times it’s the material of choice. To evade such anomalies we run Simufact Additive to ensure the build doesn’t go to waste. These applications provide real-time information to the type of environment the soon-to-be-build part is going to be placed in and the type of stress it will go through. Thus, not only is the component build as per requirements but it functions in accordance to the scenario it’s supposed to go through.

What safety measures (data/design safety) are taken by your company when you work for OEMs for 3D Printing services?

Data sharing across all our OEMs are done in Objectify’s secure in-house servers through secure firewalls which are then tagged for traceability. Hence, the idea of any data leakage is not possible within our portals. We also keep confidentiality at check at all times with our NDAs.

 What are the main barriers to 3D Printing adoption in India?

Indian manufacturing industry is in process of shift from conventional to modern technologies. India has always been late in adopting latest technologies, however we could see a huge progress in the area of technology adoption in last few years. Indian companies are not only looking for higher technologies but also have become very demanding in terms of ROI on any purchase. Additive manufacturing being innascent stage in India, lacks awareness about the applications and benefits among the manufacturing fraternity, which is one of the reason the adoption has been slow. Having said that we have seen huge improvement in approach towards additive manufacturing in last couple of years. Now there are companies that are aware of the technology and exploring how it could complement their existing manufacturing process.

Another factor is that additive manufacturing been always compared with the conventional manufacturing processes such as machining, injection molding, casting etc. For batch production, conventional methods are still cheaper. We have to understand that all these technologies have different applications and benefits. They are not going to replace each- other but complement. Companies need to understand in what area of manufacturing certain technology is needed.

Additive Manufacturing/3D Printing in India has just begun its foothold and now it’s time for it to proliferate. 3D Printing isn’t here to replace conventional manufacturing processes, rather act as a catalyst to the production process as a whole. As emerging industries have a constant need to re-engineer and develop new products, 3D Printing comes as a boon by reducing the cycle time by fractions. The primary barriers for the Indian industry are acceptance, ill-information and adaptation to change.

What products do you see 3D Printing being used for? Considering Automotive and Consumer Goods industry?

Functional components can be printed at a faster pace with 3D Printing, this results in instant testing to aerospace and automotive components during the development stage. Moreover, consolidation of components which is only possible by 3D Printing, opens a whole new avenue in R&D as it has an added advantage of realizing multiple parts to be built as one whole component.

 After the inception of BS VI (Bharat Stage VI) Fuel Compliant Vehicles Policy, Indian automotive sector has pulled up its sleeves to ensure combustion & emission units are installed into their new models. The deadline to comply as per government is 1st April 2020. To meet this deadline, Additive Manufacturing has helped to boost the testing phase. We have seen a surge in building emission units,cylinder heads, mufflers, valves and other peripheral components which will help the primary phases to mass produce these components as per BS VI compliance.

What areas are ripe for industrialization with 3D printing?

The whole department of NPD (New Product Development) and R&D in industries like Automotive, Aerospace, Space, Tooling and Medical sectors can be taken up by 3D printing as real-time manufacturing can take place as well as testing and developing can happen spontaneously. This adds value to the industries exponentially. Reducing cost, time and material waste, 3D Printing helps to ease the process from Ideation phase to Creation phase efficiently.

 

What advice would you give to an industrial company that wants to use 3D printing to manufacture

First and foremost, 3D printing isn’t required for all spheres in manufacturing. For example, not all components which are 3D Printed can certain the reduction of cost, time and material. It is upto the 3D Printing service provider to evaluate the design along with the client and suggest the options available. A simple CNC worthy component doesn’t have to be 3D Printed just for the sake of it. Hence, industrialists and engineers should look for opinions on the design sent by them to the 3D printing service provider. Even though we are in business of providing AM services, we encourage companies to firstly understand the applications and benefits of the technology an make calculated decisions.

Secondly, they should also be able to realize the available material options and processes required before sending the files to be printed. In some cases, the requisite option of metal/polymer isn’t available, but equivalent materials with almost same or sometimes even better properties are available. Engineers in the domain will be happy to suggest changes and design modification too, so it’s highly suggested that industrialists look into it as well.
