With all of the buzz that the Internet of Things (IoT) has generated, a number of our readers have asked if there was anything available for experimenters who may have interest, but not a lot of money to spend on exploring the technology. Until recently, the answer would have been, “No.” However, that all changed this month with the availability of the ARM® mbed™ IoT Starter Kit-Ethernet Edition from ARM Ltd.
In the 1980s British computer manufacturer Acorn Computers first developed the Acorn RISC Machine (ARM) architecture for its personal computers.
A reduced instruction set computing (RISC)-based computer design approach with ARM processors require significantly fewer transistors than typical complex instruction set computing (CISC) x86 processors in most personal computers. This approach reduces costs, heat and power use. Such reductions are desirable traits for light, portable, battery-powered devices and other embedded systems. A simpler design facilitates more efficient multi-core CPUs and higher core counts at lower cost, providing improved energy efficiency for servers.
ARM Holdings develops the instruction set and architecture for ARM-based products, but does not actually manufacture products itself.
ARM core processors are used in a wide range of products including the Microsoft Surface tablet, Apple’s iPad, iPhone, and iPod, ASUS tablets, Canon PowerShot digital cameras, and Nintendo DS handheld game consoles. In a word, ARM cores are everywhere.

A couple of weeks ago I attended the Hexagon Global Network (HxGN) 2015 Live conference. Although not held in my favorite destination, Las Vegas, this was an opportunity for my first direct exposure to Hexagon. In a word, I was not disappointed. In fact, the experience went far beyond my modest expectations that I had before attending the event.
I went to HxGN specifically for the metrology (science of measurement) portion of the conference with regard to sensing, inspection, QA, and reverse engineering applications – in other words what Hexagon Metrology is all about. However, metrology was not the only area represented, as the company known as Hexagon AB also has a huge presence with its hardware, software, and services in other industry segments, such as geospatial (GPS and surveying); process, power, and marine (PP&M); and security, government, and infrastructure (SG&I). It was a lot to take in and I focused on industrial metrology and related technologies – sensors and software used for optimizing manufacturing processes and throughput.
Founded in 1992 and headquartered in Stockholm, Sweden, Hexagon AB has offices in 46 countries, 15,000+ total employees, and is R&D focused with 11% of net sales and more than 3,400 employees invested in R&D. The industrial side of Hexagon AB, known as Industrial Enterprise Solutions (IES), that includes manufacturing and industrial plant facilities accounts for about half of the company’s sales. Roughly one third of Hexagon’s business is derived from metrology.

The pressing need for engineers of virtually all disciplines has become increasingly urgent as relatively few students view and pursue engineering as a career. Business seems more attractive to many, and yeah, there’s always psychology (the “new” liberal arts degree) that has a lot of sellers, but relatively few buyers, at least at the BA/BS level.
Yes, engineering education and engineers are vital for keeping our technological world moving ahead, but who keeps the underlying machinery, tools, and software moving at all? Technicians.
Whether you recognize them, or not, there are technicians in just about every field and industry. For example, automotive mechanics, machinists, cosmetologists, electricians, emergency medical technicians (EMTs) — the list is about endless. If it’s “technical,” the odds are extremely good that there is a technician involved somewhere in the chain, and that may include many links in the chain.
So, what exactly is a technician?
Technicians can be classified as either highly skilled or semi-skilled workers, and are usually an integral part of a larger process. They work in a variety of fields, and they usually have a job title with the designation “technician” following the particular category of work. For example, an engineering technician is a highly skilled, highly educated occupation requiring several years of post high school training in a formal apprenticeship and probably college (usually two year) for further education.
Experienced technicians in a specific domain typically have at least an intermediate understanding of theory and expert proficiency in technique. Because of this practical knowledge, technicians are generally better versed in technique compared to average laymen and even general professionals in that field of technology, namely engineers, for whom theory often trumps practice.
What is the Future of (Automotive) Technicians?

About a month ago I spent a few days in Boston at PTC’s LiveWorx 2015 event. It was an eye opener for me and a brief look into the future of PTC with its growing emphasis and dependence on the Internet of Things (IoT).
Recaps of the event, entitled LiveWorx 2015: PTC Drives Home Its IoT Future – Part 1 and PTC ThingWorx Converges On IoT were published shortly after the event last month.
Beyond the technologies and business strategies presented, what struck me was the relatively young crowd attending with relatively young PTC PR people pushing the IoT platform. Sold out with over 2,300 attendees (up from ~350 in 2014), the draw was similar or maybe more than this year’s PTC Live Global user event. Although Creo and Windchill were certainly present at LiveWorx, they took a back seat to IoT offerings, such as ThingWorx, Axeda, and others.
So what does IoT really mean? I don’t know either because it’s evolving so rapidly and all participating vendors define it so that it accommodates what they offer best. In other words, until standards are established, the definition continues to evolve. I will admit, however, that PTC currently has a leg up on virtually all of the competition for IoT in its traditional design, engineering, and manufacturing space.
A standard definition is in the works, however, and IoT generally refers to uniquely identifiable objects and their virtual representations in an Internet-like structure. The term Internet of Things was proposed by Kevin Ashton in 1999, although the concept has been discussed since 1991, so it’s not exactly brand new.
According to PTC, the Internet of Things has the potential to create trillions of dollars of new economic value in the coming decade. To capture this value, manufacturers will rely on new applications that enable the creation of smart, connected products, thus PTC’s interest and commitment, as shown in the brief video below.

An independent consulting firm and industry source that we know quite well, Wohlers Associates, Inc., recently released the Wohlers Report 2015, the company’s annual detailed analysis of additive manufacturing (AM) and 3D printing worldwide. According to the Report, in 2014, interest in 3D printing reached an unprecedented level and exceeded the $4 billion milestone. The phenomenal attention to AM began in 2012, was sudden, and has continued to proliferate since then.
Wohlers Associates is widely recognized as the leading consulting firm and foremost authority on additive manufacturing and 3D printing. This annual publication has served as the undisputed industry-leading report on the subject for two decades. Over the 20 years of its publication, many have referred to the report as the “bible” of additive manufacturing (AM) and 3D printing—terms that are used interchangeably by the company (and industry).
Wohlers Report 2015
The market for additive manufacturing, consisting of all AM products and services worldwide, grew at a compound annual growth rate (CAGR) of 35.2% to $4.1 billion in 2014, according to Wohlers Report 2015. The industry expanded by more than $1 billion in 2014, with 49 manufacturers producing and selling industrial-grade AM machines. The CAGR over the past three years (2012–2014) was 33.8%.

We’ve been in Long Beach, California all week at SME’s RAPID 2015 conference and exhibition. If you want to learn what’s new exciting in things 3D, this is the place to be. Hardware and software vendors, service providers, distributors and resellers, and educational institutions all showcase new offerings in 3D printing, scanning, and additive and subtractive manufacturing.
RAPID is an interesting mix of industry experts, pundits, users, and people just curious about this fascinating 3D world that continues to grow at an exponential rate. This year about 4,000 attended RAPID with almost 200 exhibitors
RAPID is about the most recent developments in the field, as well as what may be coming in the future. A number of technologies, techniques, and innovations are discussed during technical sessions, but this year, we found among the most interesting topics to be 3D bioprinting and 3D printing in space.
The first morning’s keynote was made by Jason Dunn, CTO of Made In Space, who talked on the topic of “Bringing Additive Manufacturing to Space.” The company was founded in 2010 with the goal of enabling humanity’s future in space. It has developed additive manufacturing (AM) technology specifically for use in the space environment (no easy task). By manufacturing space assets in space, as opposed to launching them from Earth, the company is attempting to accelerate and broaden space development while also providing unprecedented access for people on Earth to use in-space capabilities (the ultimate goal of a business model to monetize its cash outlay in space on earth).

Last week at LiveWorx 2015, PTC made several major product and strategic announcements around the Internet of Things (IoT) and their implications for the future of PTC. A couple of the most prominent of these product announcements were ThingWorx 6.0 and ThingWorx Converge.
Before being acquired by PTC about 18 months ago, ThingWorx realized that making IoT a reality required an ecosystem of complementary technologies that enable “things” to be created, connected, operated, and serviced. With the ecosystem established, applications that capitalize on the data these “things” generate can be developed.
According to Russ Fadal, President & General Manager, ThingWorx, a PTC business, it’s estimated that in 2010 there were approximately 7 billion connected smart devices in the world. That number is expected to be in the neighborhood of 1 trillion by 2035. That’s explosive growth, to say the least!
He said that today IoT is challenged because 80% of resources are dedicated to infrastructure and 20% for applications, and he would like to see those percentages reversed. Other issues that he, PTC, and the IoT industry as a whole are trying to resolve include security, predictable performance, 10X+ faster production and implementation, and what to do with the mountains of data generated by IoT devices. Security is especially important because it is not an event, but an ongoing process that will never go away. No small concerns here, therefore the evolution of the platform ecosystem — ThingWorx.

As exciting as the 3D printing/additive manufacturing (AM) space has been the past several, especially the last couple, its unbridled enthusiasm and expectations couldn’t be expected to go on forever, and they’re not. Stratasys reported less than anticipated financials for Q1 2015.
All was not doom and gloom for Stratasys, however, as the financials also include the following:
Stratasys Presents a 3D Printed Aircraft Interior at EuroMold 2014
Fred Fischer, Director of PolyJet and FDM Applications at Stratasys, presents an aircraft interior 3D printed using a unique combination additive manufacturing technologies. The presentation was filmed at Stratasys’ aerospace-themed booth at EuroMold 2014 in Frankfurt.

So, you think that the Internet of Things (IoT) is a fad? Based on my experience at PTC’s LiveWorx 2015 in Boston this week, IoT is a big part of the future, not only for PTC, but for all of us.
Still not convinced? Just the attendance figures alone from this year over last might help convince you – LiveWorx 2014 (~350 attendees); LiveWorx 2015 (>2,300 attendees). Numbers don’t lie and that shows the growing interest in IoT.
Because of the amount of material covered in just a couple of days, and the major implications surrounding IoT and PTC, I’ll be writing about some the major (and some minor) technology and business announcements, as well as how this all fits together and might shape PTC’s strategy going forward, including:
