The New Big Cad/Cam Opportunity in India

Over the past decade or a bit more, i have witnessed Cad/Cam technology have an impact over many industry sectors. Of course, the initial adoption started with the automotive companies moving from drawing boards to Autocad to 3D Modeling using feature based design. For automotive, the results were huge that translated directly to their top line results. Now, with CAD/CAM and other systems in place, automotive companies are able to produce better designs much faster than they could have ever imagined. But the actual beneficiary to this was the end user, who over the past decade had a much better driving experience and had new models arriving every year from different companies. All this could never have been possible without Cad/Cam.

The adoption of Cad/Cam by automotive companies cascaded a demand from their suppliers and other engineering companies who realized the importance of Cad/Cam adoption and slowly started to adopt the same. As a result, they were able to reduce costs, enhance product quality and also reduce the entire product lifecycle time. I myself have witnessed the adoption of Cad/Cam in many sectors starting to automotive to industrial and now to jewellery. Jewellery industry too now has a sizeable adoption of Cad/Cam. Although the larger companies have adopted the technology long back, smaller jewellers including family run firms and even retailers and now looking at Cad/Cam and the adoption is now increasing day by day. There is a huge opportunity in this segment too.

But the big Cad/Cam Opportunity today is in the dental field. In India, the dental industry is still 95% using low technology and Cad/Cam can revolutionise this. With the emergence of new dental materials that are far superior than the conventional ones, it will surely drive the demand. Also, Cad/Cam offers unmatched accuracy and quality that a patient would demand once he experiences the result. There are some significant and key benefits that Cad/Cam technology can offer to the dentist and those are accuracy, speed of delivery, reliability of results and lower manual intervention during the operation. For the patient, it offers a reliable implant or restoration that is customised as per their anatomy and therefore will be long lasting and painless. Also, newer materials like zirconia or glass ceramics offer strengths that are far superior to conventional materials. 3D printing using wax based systems are also used for producing complex implants, restorations and cast partials. Typically, today only about less than 5% of dental restorations and implants are produced using Cad/Cam technology, hence there exists a huge opportunity for Cad/Cam penetration in this segment as well. Hopefully the next decade will see a lot more of Cad/Cam in the dental labs and lot less patients complaining about the broken restoration.

Implementation is the Key!

CAD/CAM has great potential in the next couple of decades. Various segments are now experimenting & implementing CAD/CAM much more confidently. When i started marketing CAD/CAM products ( and thats not too long ago which is about 10 years back) the only segment using CAD/CAM & RE/RP were automotive oems, its suppliers and the consumer industry. Products were expensive with 3D softwares costing tens of thousands of dollars and the only companies who could afford it were those who were in dire need of it or those who were asked by their customers to implement it. However a lot has happened over the past decade. Industry segments like dental, medical, fashion, shoe, marine, jewelry, furniture, films and set design are adopting CAD/CAM in a big way. There are many companies now competing with each other which has eventually led to better products, reduced prices and reduced monopoly. I still know how AutoCad dominated the 2D market when they had no competition but now they have to compete with products such as Intellicad, 2D softwares from 3D modeling companies which has been a challenge for them. Same is the case with other companies & brands. They are now in a position where they have to be on their feet for new entrants & plan their pricing/sales strategy accordingly.

But the good news is that the market has grown - and grown multi-folds. So eventually companies in spite of facing competition are growing at a steady pace and will continue to grow in spite of new competition. The customer has many options in every segment of CAD/CAM. A novice user is bound to get confused on choosing the right product coz every day something new is coming up. You may end up buying a product which may not be the right choice or may get obsolete tomorrow. With so many products and brands - differences in prices and sales people looking to push products - the only key would be implementation.  Today there are many companies who focus on selling products but don't understand the true meaning of implementation. Implementation can only happen when the seller is aware of the industry he is selling to - not just box selling. Trust me - in my experience most of the companies who have invested in technology do not utilize it due to lack of knowledge and not due to lack of features in the product. If you want to just make contact lists, why do you need Microsoft Excel, you may just as well use Open Office which is free. Most of the customers try to get a price bargain when they buy a technological product rather than worrying about the implementation part. I mean even if you save a couple of hundred dollars in buying a product, what good is that if you dont use the product to its fullest potential - its a sheer waste of money. I would rather pay the extra hundred dollars and have a complete implementation plan so that i actually am able to get what i want.

The future is bright for CAD/CAM companies & vendors but the key here would be looking at industry verticals and segments and offer a complete implementation of a solution rather than just pushing a product. It doesn't matter which product you buy, but it does matter that you use the product in its fullest potential and not use a smart phone only to receive and make calls.

And then there were more...

The 3D Printing Industry has seen a lot of activity over the past few years with many new technologies entering the market ( many of which are clones of existing technologies due to expiry of patents ) leading to a great amount of confusion in the minds of a potential buyer. However, the emergence of low cost printers has given the average engineer to experience 3D printing in real time but it is high time, the products have to be consolidated to give the customer some clarity on which products to buy. Mergers & acquisitions have been in the limelight with 3D Systems & Stratasys going on a buying spree with 3D Systems acquiring ZCorp, RapMan, Cube etc & Stratasys acquiring Solidscape & Objet ( although with Objet its more of a stock swap & merger). However, my point is that these acquisitions have created somewhat of a redundancy in the product lines of these companies which has to be consolidated. For eg : A customer who wants to print average quality models would think ten times to go for an expensive printer given the choice of low cost printers like rapman by the same company. Also, a prototype need not be of a specific material ( most of the times ), hence the confusion increases further since there has been a plethora of multi material low cost printers in the market. I would recommend a market specific approach where products such as rapman, botmill etc are consolidated first with limited options catering to specific markets. Also, i see a lot of redudancy in development projects where technologies which are available in the market ( For eg : Digital Light Projection (DLP), Fused Deposition Modeling (FDM)) are re-engineered thus leading to products which are redundant & also back to their initial phases. The best they can do is provide an inferior version of the printer at a lower cost thereby creating a threat to the existing business who have perfected their technology.

The entire manufacturing industry needs solutions for making direct parts from additive manufacturing. This requires  companies spending resources on research to perfect the existing technologies rather than offering products with inferior quality & cheaper price. These require significant amount of core research since most of the printers available now cannot produce direct parts & if they can they can't do it economically.

Having said that, I feel the day is not far where we start producing end products directly from CAD models economically & quickly by using additive manufacturing.

AeroShow India 2011.

Last week i had the opportunity to visit the Aeroshow held in Banglore. Although this was my opportunity to visit, i must say it was a great experience. As we ( me & Bala ) arrived in Bangalore & were traveling down from the airport to the maincity, the entire ambience on the street showed how important the Aeroshow was to the city of Bangalore with huge hoardings on our way in from Aerospace manufacturers including SAAB, Alpha Design, Mahindra Aerospace. We had meetings on the same day, hence we had to schedule our visit to the Aeroshow the next day. 
When we entered the car park, we saw some shuttles & i though maybe that would lead directly to the entrance, hence we took one of them & were happy to not get stuck up in the car near the entrance as in any major trade show, thats a nuisance with a row of cars in a big queue. Although being in India, the driver took us to some other entrance & we had to walk our way back to the main entrance where we saw a huge queue for registrations ( i wonder when will our organizers learn to be more organized in such petty things by simply having more registration counters). Nevertheless, the queue was the same for business visitors & general visitors. We had already registered online but since we did not get a print of the registration email & just got the pin number with us, we had to go to a nearby cyber & get the printout.
However, we were entertained by the fighter jets rocketing though the skies all the way, hence it was not a bad experience. Finally, we entered the show at about 12 noon & spent some time at the booths. Since through Hindustan Magnesium, we are in the business of supplying aero grade magnesium castings, our prime interest was to evaluate the major players in the aero industry & the magnesium usage trends in the same.
The prime exhibitors were from Israel, Russia, France, Sweden, UK, USA, Italy, Germany & India. The major exhibits were UAV's, aero suppliers including electronics, systems, engineering design companies in the booths. Although there were also country specific pavillions displaying their technology in aerospace. UAV  ( Unmanned aerial vehicles) manufacturers seemed to be there in plenty including a couple of India, i guess there is a lot of emphasis these days for these systems in different departments of any country ( just today i read about 24 UAV's being purchased by the Mumbai police for anti-terrorism ). Further, we came across different missiles on display from Russia, Israel & other countries on which we came to discuss about the business of destruction which is pretty ironical because the price of these systems is not based on the material cost but the destructive ability of the system. Some may be purchased and may not be used for years together, so we never would know whether it really works or not. But since we have a defense budget of more than $20 billion dollars every year, a lot of shopping is done on these systems. 
Coming outside the hall, we came across the Mahindra Aerospace booth & it was pretty interesting to know that Mahindra is entering into Aerospace as well. It seems that Mahindra has acquired some aerospace company in Australia & had a commercial 10 seater ( or so ) aircraft on display. On enquiring, i was told it costs 3 Crore and on a first glance, it was not at all impressive. On a closer look, it looked like a toy plane with doors resembling the old fiat car, age old instrumentation which were entirely analog & poor upholstry. I wonder who would spend that kind of money when you can buy much better planes at much less.
The highlight of the show were the fighter jets on display which were taking turns to display their muscle in air. Amongst them were the Rafaele from france, the EuroFighter from European Union, the SAAB from Sweden, the F16's & F18's from USA, the LCA Tejas from India and a couple more. Looking at the air display's i was particularly impressed by the maneuverability of the SAAB fighter jet from Sweden ( they also had a huge booth where they displayed the miniature version of the jet which was awesome ).
Towards the end, we had the opportunity to visit the booths of HAL, ADA, BDL, GTRE & CVRDE & meet some of our old customers from these organizations there, it was great looking at our progress in aeronautical engineering as well, however there are many milestones to be covered. We look forward to working with all these esteemed companies in India & abroad and are extremely delighted to be part of this great industry. 
Looking forward to my next aeroshow & i would love to visit the Paris Aeroshow as well which is in June but i wonder if that would be possible this year.

The Future is Light, Hindustan Magnesium Products is born.

We are all part of the "rising fuel price" conversation at some point or another which is an issue we often like to argue about & blame politicians and taxes. However, the fact remains that the fossil fuel resources in this world are limited resources which would at some point of time get depleted and as we approach that scenario, we will be faced with paying higher and higher prices for our consumption. Although a lot of research is being done in exploring alternative fuel systems, the biggest challenge is replacing the same in transportation systems. Nuclear energy offers a promising alternative for electricity generation, however its usage in vehicles is far from reality. Alternative fuel systems like hydrogen, fuel cells, solar would be a viable option in transportation systems, however they will need lighter vehicles to propel. Imagine yourself carrying a metal suitcase with your luggage vs carrying the newer plastic ones. You obviously would spend less energy carrying the latter. The need for lighter transportation systems is imperative & alternatives are limited but promising. Amongst them are carbon fibre structures, magnesium alloy castings, high strength plastics etc. Magnesium offers the highest strength to weight ratio with its weight almost 2/3rd of Aluminum.
A couple of years back, when my friend Bala ( who is more of a techie & quite an engineering genius ) approached me with this concept of setting up a magnesium based foundry, the concept looked appealing. However, there were a lot of challenges including technical & financial. The technical challenges were huge since the know how of casting magnesium is held by only a few companies in the world & is not available off the shelf. Mg is an extremely fussy material to handle in molten stage since it oxidizes almost instantaneously when exposed to atmosphere & reacts violently with water. It can even cause an explosion, however when casted under specific parameters, it offers itself to casting. Now to recognize those parameters for aerospace  & other complex components is a challenge which many companies have taken years to acquire. However, with Bala we managed to cast mg within a year. In the process, we established new processes & techniques which are extremely innovative & due for patent registration. The financial challenges were also as much since the amount of research done required huge inflow of capital.
With the advent of 2011, our concept has finally turned into reality with the registration of Hindustan Magnesium Products Pvt Ltd ( www.hindustanmagnesium.com ) as a corporate entity and an order from ISRO to kickstart the new year.
Hindustan Magnesium Products would contribute to a new era of light weight engineering technology catering to industry segments like aerospace, space, defense, automotive, consumer & industrial machinery. Our mission is to make a lighter world.

3D CAD For Everyone.. I Mean that Literally.

I wouldn't much boast of my recent following of MCAD softwares since lately my company has been more involved in working with jewelry companies rather than engineering companies but until about a couple of years ago, i have been pretty actively following the developments of major CAD softwares around the world. My first experience with 3D CAD was during my college days when i put my hands on I-deas Master Series 8.0 working on an Open GL environment with 1GB of RAM, this was in 2001. I had designed an entire 4 -cylinder engine on the software & it took me almost a month to do that. With that 1 month of experience, i had decided to get into CAD/CAM. Further my first job got me into selling CAD/CAM/CAE softwares to various engineering companies across Western India where we had to demonstrate  these solutions to various small & medium scale companies. To my surprise, i found thousands of companies still using 2D AutoCAD & most of them used pirated licenses. Inspite of convincing the technical features, we were unable to convince the price/benefit ratio since these softwares were priced extremely high ( more than Rs 2,00,000/- ). 
At that stage only companies who had that kind of a turnover & an imperative requirement invested that kind of money. But i found that a vast majority ( almost 95% of the companies ) would go in for 3D CAD if given an affordable solution..... Alibre ( www.alibre.com ) has done just that !
My company has been distributing Alibre Design for almost 5 years now, when we tied up with the company, the product was priced around 5 times cheaper than mainsteam CAD softwares, still a very good proposition & we managed to sell many licenses even at that price. Recently, Alibre surprised the world by slashing the Alibre Design software prices by almost 5 times further down. The base software is now available in India at Rs 18,000/- which is even 50% the price of AutoCAD.
The product is very good, although it does not have all the fancy tools, it is a pretty robust software with capabilities as good as any mainstream software. With this price, now even students & professionals can afford to buy a license & for those who can't, they can use the free version of Alibre Xpress which has pretty significant tools  as well...

CAD/CAM Technology at EuroMold




December 25th 2009:
Recently i had the opportunity to visit EuroMold 2009 (infact, it was my first visit to EuroMold, although i have been craving to visit since almost 5 years now) & the experience was great! Supposed to be the ultimate exhibition for CAD/CAM technology, most of the technology gets launched in EuroMold, so you have the opportunity to get a glance of it before it comes to the market. Since my domain is restricted to CAD, RE & RP, i was particularly interested in evaluating technologies in the area of RE & RP ( especially 3D Scanners & New RP Introductions) & i must say that a few products caught my eye.
I would like to highlight a few products in my blog in each technological area which interested me:
3D Scanning :
Since my company implements Solidscape in India ( the most precise RP machine in the world), my primary objective of evaluating 3D Scanners was to have a complementary product to Solidscape in the area of jewelry, dental & engineering. I had actually carried with a small statue of Lord Krishna & Lord Ganesh to be scanned & i was looking forward to scan the statue so that i can directly get a very precise STL point cloud which i could print using the Solidscape R66+. The basic intention was to eliminate surface modeling since once we end up doing that especially for the jewelry models, then it is as good as making a model from scratch. So the point cloud had to be without noise & should capture all the features required for printing. I came across number of scanners but shortlisted 3 of them based on the price as well ( around 20,000 Euros ). The scanners i was evaluating was 3shape, Scansystems, I-metric & SmartOptics ( which i came to know at EuroMold through the Solidscape Turkey reseller).
My first visit was to the Smart Optics booth & i handed over the model to Dr Ralf Lampaizer - the Head of Development. His first reaction at looking at the model was " This is a complex model". I was pretty sure that this was a challenge for his scanner. Now SmartOptics had 2 models displayed at EuroMold, from their website i suppose the one which they recommended me was the Activity 91 scanner with a build volume of 200x200x150mm which they told me would cost 29,000 Euros. So we tried scanning the model & as expected we had to powder coat it since the model was absorbing all the light thrown by the projector. Although the scan was decent enough, it failed to capture all the minor details.
Further to this, i visited the Scansystems booth. At first impression, i thought that they would not be able to do the job but i had a visit to their office scheduled after the EuroMold to get the scanning done. At their office in Pisa, when i gave the model to be scanned, i was immediately impressed with the speed with which the scanner was capturing the data. In a single scan, the scanner was able to capture most of the geometry - the same geometry had to be scanned multiple times in SmartOptics to get the cloud. The only problem was that since in their dental scanner, 3d indexing was not available so we were not able to get the features at the bottom of the model. So, i left the model at the Scansystems office so that they can scan the same with the ScanProbe LT model which had to be calibrated for this model with the help of a calibration plate (i am still awaiting the point cloud, but i am sure it would be pretty good).
Regarding 3shape, unfortunately i was unable to scan the model at EuroMold because the first day, i was unable to get the model from my hotel & Mr Birk whom i had met had left on the next day. I took the model to their stall the next day, but one of their marketing managers refused to scan the model for me at the show.
Finally, for evaluating the I-metric scanner i visited their office in Courgenay close to Basel in Switzerland. The location of their office was extremely beautiful & my train ride from Milano to Basel was supercool & both me and my wife ( who accompanied me on my trip ) enjoyed the landscapes there. At the I-metric office, i met Damien & Horst Beyer & they introduced me to their IScan S series of scanner which is priced around $25,000/- & is suitable for dental & small sized models. Although the scanner was a little slow, i thought the scanner captured data more accurately but it had problems capturing fine features such as filigree on the statue. Also, the biggest problem was the alignment of scans since we had to manually align each & every scan by choosing points. But i was definitely impressed by the accuracy & the level of details it could capture. I still await the point cloud from them so that i could print it on Solidscape.

Going back to the technology at EuroMold, a couple of interesting products in the RP domain that caught my attention were the Rapman RP Machine. Now believe me or not, this RP machine costs just $900/- & can print fairly good parts.
Although, it makes me to wonder, just where is the RP industry heading. At one end, you have SLS technology with products starting from $2,00,000/- & at the other end, you have RapMan for $900/-. I also saw the Solido3d printer offering its printer for under 3000 Euros, it seems that they want to sell their printer to every engineering company in the world who would want to print their products just for visual inspection. Finally, another machine that caught my attention was the Huntsman new RP machine based on optical switches. The surface quality was better than SLA & i wonder how would they compete against their own customer - 3D Systems.
Finally, at the show i had the opportunity to meet Mr David Bothwell - the CEO of Solidscape Inc & i was immediately impressed by his intellect & level of technical knowledge. I also managed to spend some quality time with Fabio (VP-Worldwide Sales) & the Solidscape team at the Solidscape booth - the most precise & sophisticated RP machine available on the market which made me really proud that i was associated with such a technologically advanced product.

I am really looking forward to visit the next EuroMold as well!
