ARCHIVE FOR THE ‘3d-printing’ CATEGORY

Within the last decade technology has altered the way field service companies operate irrevocably, yet the technology now emerging on the horizon could change the game even further.

Across the last few weeks Field Service News has been looking at some of the technologies that we think will be impacting on field service across the next year.

In part one of this series we looked at Wearables, Cloud and NFC and in the second instalment we focussed on IoT, Big Data and Cyber Security.

Now in this the final section of the series we take a look at where Drones , 3D Printing, 4G and Integrated Platforms will fit into the field service landscape.

A bit of a buzz around Drones…

As we entered 2014 there was still an incessant buzz around Drones that had been sparked by Amazon’s fantastic claims that they were investing heavily in research and development of Drone technology. Accompanied by an incredibly slick video showing an Amazon branded Unmanned Aerial Drone (UAD) picking up a parcel from the depot and happily buzzing away as it delivered it right to the recipients front door.

At the time Field Service News looked at the proposition including questioning whether it was all just a fantastic PR exercise or whether there was indeed potential for a drone based delivery service.

 

A year on and Amazon’s delivery drones have still yet to materialise however, with the cost of drones plummeting (a small drone with a camera capable of recording decent quality footage can now be picked up for between £50 to £75) there is certainly potential for drones to be used in field service.

Indeed in the UK there are now over 300 companies licensed to use drones for commercial reasons and whilst delivery drones may seem far-fetched and are subject to an awful lot of as yet undefined regulation, there are plenty of applications for drones that could benefit field service.

For example, a visual inspection on an inaccessible roof of a building could be required. A UAD could provide this visual check without the need to erect scaffolding potentially saving at least a days labour. Or what about large manufacturing plants that can in some cases span many miles. Again manual visual inspection could be a long drawn out process, but with the aid of drones the time to complete the task could be slashed.

3D Printing is on the verge of a true breakthrough…

Perhaps my favourite of all emerging technology for the sheer Star-Trek-ness of it all is 3D printing.  The idea of something appearing out of nothing just seems so, well for want for a better word… cool.

 However, it is not just the ‘cool’ factor that makes 3D printing so exciting. More than any other technology identified in this series 3D printing has the potential to completely change business, as we know it.

 

Economies of scale no longer come into play, the cost of producing one unit is the same as the cost of producing thousands of units. Meaning that companies will be able to operate on lean methodologies far easier.

Then we consider the benefits for field service. Imagine the impact it could have if a field service engineer is able to print 3D parts on site. No more parts ordering and delays, the engineer having identified a part is worn could simply print a part there and then.

Whilst it might seem like something from science fiction the truth is this technology could just be around the corner. We know that it is possible to create parts strong enough for commercial applications via 3D printing. A recent example being manufacturer of helicopter parts Turbomeca who are now producing fuel injector nozzles for its Arrano helicopter engines.

We have also seen smaller and more affordable consumer 3D printers come to the fore in the last year.

So is it that big a leap of faith to foresee a field based 3D printing solution being rolled out in the not too distant future?

4G – a key enabler across field service

If 3D printing is the most exciting of technologies to make this list then it could be argued that 4G is perhaps the most understated.

The reason I say this is that when it’s older brother 3G entered the scene it was a complete game changer. The leap from WAP to 3G (okay technically WAP to EDGE to 3G) was an unprecedented stride forward in mobile computing. It coincided with early smart phones and it changed the way we work forever.

By the time 4G rolled along we had already got used to smart phones and fast wi-fi speeds too. So whilst being able to access broadband speed internet on the move is of course pretty incredible – the ‘wow factor’ that arrived with 3G just hasn’t quite been there.

 

3G changed the world. 4G just does everything 3G does only better and faster.

However, if we take a step back then the impact 4G will have is truly incredible, especially for the field service industries.

The increase in mobile data speed means access to knowledge bases is an easy and quick option for field engineers. Similarly the ability to hold high quality video conferencing from one onsite engineer to another is again made possible through 4G.

And with both Vodafone and O2 promising 98% coverage across the UK by the end of 2015, 4G in the UK at least, will very soon be one of those technologies, like smart phones themselves, that we just don’t remember how things worked before it came along.

Integrated field service platforms will continue to be at the fore…

The final inclusion on the list is one which has been making a slow rise to prominence out of necessity as much as anything else.

Across the last year we heard a lot about integrated service management platforms. A number of providers have developed full service lifecycle solutions and with integration issues being at the fore for field service companies looking to move to a next generation solution there is a solid case for exploring such a solution.

 

However, whilst the platform approach has merits, integration with other systems has also become a significant focus for many providers also and this appears to be becoming a growing trend, which could make selecting various best in class options more readily available.

What is key however, is that whether you opt for a full platform approach or a number of individual ‘best-in-class’ with full integration, your service management solution should no longer have any restrictions when it comes to the flow of data.

The ability to breakdown siloes is key to the successful operation of a field service organisation and the technology is now readily available to make sure this is possible – easy integration will be a major selling point for service management providers and those who fail here will struggle to compete.

 Be social and share this feature

Do you ever stop and think that the technologies that are now commonplace in the field service industry seem to be lifted straight from the pages of Star Trek creator Gene Roddenberry’s notebooks?

Certainly modern smart phones are on a par with the communicator devices found on the Enterprise, and now we are seeing the replicator come to life in the guise of additive (or 3D) printing. But what exactly is 3D printing, how does it work and what can it mean to field service?

3D printing 101:

As with most technologies, the background of 3D printing actually dates back much farther than it would appear at first glance. The first origins of the technology stretch back over 40 years to the late 70’s although the first working 3D printer is credited to Chuck Hall of 3D systems back in 1984. However, it wasn’t until the turn of the century that we began to see the technology finally become a commercial reality and since then there has been large growth in the sale of 3D printers as their price has become more and more accessible. In fact the 2012 figures put the market at $2.2 billion worldwide, an increase of 29% year on year.

The process itself involves making a three dimensional solid object, which can be virtually any shape from a digital model created using computer aided design (CAD) software.  In simplistic terms this is achieved by laying successive layers of material on top of each other. Essentially this is where 3D printing differs from all other forms of manufacturing, in that traditional methods start with a block and then subtract material until it is the right shape, in 3D printing you start with nothing and then add layers (hence the alternative name of additive printing) of material to build your product.

Within the last few years we have seen the techniques used in 3D printing (of which there are now many variations)  leap forward and products as diverse as clothing, turbine parts and even chocolates can now be created via a 3D printer.

3D Printing in the mainstream:

With the 3D printing industry now on set to explode into a fully-fledged mainstream industry we are seeing a number of companies now entering the market with home based 3D printers, most of which tend to look like a high end coffee machine and are available from anything for £500 to £3,000. In fact the market place is already becoming crowded with specialist makers such as MakerBot, Ultimaker and Cubify all competing with a variety of models, and surely it is only time before we start seeing bigger brands like Motorola or Sony enter the market place as well.

At the other end of the scale, there are companies like Makerbot parent Stratasys, a 3D printing company formed way back in 1989,  that offer 3D production facilities able to create specialist parts that capable of being both durable and intricate enough to be used in industries such as Automotive, Commercial Manufacturing and Aerospace.

Another big benefits of the additive process is that unlike traditional manufacturing of parts where the production run of a small number of a specific part is often simply uneconomical, the cost of manufacturing each individual part remains constant  regardless of the size of production run. This means that one off manufacturing of a part is now a completely feasible concept financially.

Also with any technology or as the market grows, so does competition, which in turn drives performance. Perhaps the most significant and dramatic improvement we have seen as a result of growing competition in this space is the speed in which the actual printing process is now completed. I remember seeing 3D printing for the first time just a couple of years back and whilst the end result was undoubtedly impressive it was still a relatively slow process. Today we are seeing print speeds of under 15 minutes for smaller to medium sized pieces.

So what does this mean to field service?

Well for a start lets take the two sides of the industry discussed... In home 3D printing,  we have seen a drive for smaller, more mobile printers and in industrial 3D printing we are seeing materials such as metals and high performance thermo plastics being used to create parts durable enough to have genuine commercial applications. Surely it is just a matter of time before we see these two elements converge to give us portable manufacturing capabilities?

In the not to distant future could we see field service engineers arrive on site identify which parts of a product need replacing and simply head into the back of the van, upload the specifications and print the part they need? With no need to wait for the parts to be firstly ordered and secondly delivered, we would be seeing first time fix rates soar.

How about we combine this technology with another emerging technology namely machine to machine (M2M) diagnostics.  Rolls Royce jumbo jet engines for example are already self monitoring, where the engine itself has it’s own built in computer system that relays information to their field staff.

It does not require a huge leap of  imagination to take this a step further... As soon as the engine’s computer reports a minor fault in one of it’s components it transmits this information to a local field team waiting at it’s next scheduled landing destination. The required part is then printed automatically on site thus allowing the field service engineer to quickly fix the issue with the freshly printed required replacement part ready to hand. An interesting concept isn't it?

Whilst the technology is still perhaps a few years away from being perfected to these levels of sophistication, it would seem that 3D printing could genuinely live up to it’s reputation of being the second industrial revolution and it’s impact on field service could indeed be quite spectacular.
