Last month at the RAPID + TCT event, many new things were presented and among those was GE Additive’s setting a target of growing its new additive manufacturing business to $1 billion by 2020, and selling 10,000 metal 3D printing machines in 10 years, building upon acquisitions it announced last year.
“It’s a big number,” said Tim Warden, senior sales director of GE Additive. “That’s why they’re investing heavily,” he said, referring to GE.
GE controls Concept after agreeing last October to buy an initial 75% stake in the German company, with plans to acquire the rest over an undisclosed number of years. The GE Additive turned to Concept Laser after a previously announced deal with SLM Solutions fell through.
The company estimates that it ultimately can expand additive manufacturing into a $10 billion business. GE owns more than 70% of Arcam but doesn’t have full control of the Swedish company.
The following video shows GE Power’s advanced manufacturing facility in Greenville, SC to learn about GE Additive’s metal 3D printing process for creating a gas turbine component that is used to power homes.
GE Additive and the Power of Additive Manufacturing
For now, “We’re concentrating on Concept where we can do what we want to do,” Warden said. “We’re going to support Concept in every way possible.”

Las Vegas in June . . . Good idea or bad idea? I’ll try and stay neutral on this one, but this town is not exactly my favorite, regardless of time of year. However, it’s always worth the trip when a company like Hexagon invites me for its annual international conference, HxGN LIVE 2017.
What is today Hexagon Manufacturing Intelligence (MI) grew up and out of what was known as Hexagon Metrology because it has grown far beyond just measurement to encompass virtually all aspects of product development from design and manufacturing (with the acquisition of Vero Software) to simulation (with the acquisition of MSC Software) to inspection and statistical analysis (with the acquisition of Q-DAS). This is all literally tied together with the so-called Hexagon Digital Thread. The newest part of this digital thread is Smart Quality, an online quality lifecycle management software platform that uses the quality data stream across the various phases of manufacturing, providing knowledge through comprehensive statistical analysis, visualization, and workflow management that enable real-time process improvements. I found Smart Quality to be one of the most interesting and significant aspects of HxGN LIVE 2017 (with more to come about it specifically in the near future).
Hexagon’s President and CEO, Ola Rollen at HxGN LIVE 2017
Hexagon is an interesting company and its growth and value have been enormous over the past few years, especially after hearing the company’s President and CEO, Ola Rollen, admit that 10 years ago virtually no one knew who or what Hexagon was. Since 2000, Hexagon has acquired around 100 companies, such as Intergraph, Brown & Sharpe, and more recently, MSC Software. According to Rollen, 50 percent of Hexagon’s growth can be attributed to acquisitions and 50 percent to organic growth, but that the latter will become a bigger contributor going forward.

The spring season seems to be the time of year when many companies and professional organizations hold their annual conferences, and this spring was no exception. I’ve attended several events in the past few weeks and noted striking differences of two of them — divergence at RAPID + TCT 2017 and convergence at LiveWorx 17 — and that’s how I want to wrap up our spring 2017 trade event tour (although I have one more next week).
Divergence at RAPID + TCT 2017
Diverge (dih-vurj, dahy-): T
3D printing/additive manufacturing (AM) are about making something digital into something analog. Although the technologies are 30+ years old, many things are still being done as they were in the beginning, such as building 3D models, exporting STL data, etc. However, several aspects of AM are diverging from its historical roots.
For example, the first AM materials were polymers, and they still account for ~85% of all materials used, but metals are coming on strong and now account for about 14% of the materials used. The range of materials being used, though, is constantly increasing — everything from ceramics to composites to food to living tissue.
Panel Discussion at RAPID + TCT 2017
Volume quantities are also diverging from one-offs or small quantities for rapid prototyping to real production quantities where the costs can be justified when costs go down and production speed goes up.

PTC’s user conference in Boston last week (LiveWorx17 ) covered a lot of ground — everything from Creo to Windchill to augmented reality (AR), but the focus of the event was PTC announcing the launch of its newest version of ThingWorx Industrial Internet of Things (IoT) platform – ThingWorx 8. According to the company, with this update, ThingWorx evolves into a more robust, comprehensive industrial IoT (IIoT) technology offering. PTC also announced a new lineup of ThingWorx-powered apps for the manufacturing environment, as well as ThingWorx Studio support for native authoring and publishing of AR experiences for Microsoft HoloLens.
Interestingly, PTC’s VP of Corporate Communications, Jack McAvoy said that two of this year’s three main messages for LiveWorx17 revolved around ThingWorx as more than a platform and the evolving ThingWorx ecosystem through physical/digital convergence.
PTC’s foray into IoT got a big boost about four years ago when it acquired ThingWorx, creators of a platform for building and running applications for the Internet of Things (IoT), for about $112 million. The acquisition of ThingWorx immediately positioned PTC as a major player in the emerging Internet of Things era.
According to a research report, Disruptive technologies: Advances that will transform life, business, and the global economy from the McKinsey Global Institute, the Internet of Things has the potential to create economic impact of $2.7 trillion to $6.2 trillion annually by 2025. The firm believes perhaps 80 to 100 percent of all manufacturing could be using Internet of Things applications by then, leading to potential economic impact of $900 billion to $2.3 trillion, largely from productivity gains. For example, with increasingly sophisticated Internet of Things technologies becoming available, companies can not only track the flow of products or keep track of physical assets, but they can also manage the performance of individual machines and systems.

Last week at the RAPID + TCT conference in Pittsburgh, I made a point of catching up with my friend (and fellow Coloradan), Terry Wohlers, President of Wohlers Associates. I caught him after his excellent keynote presentation where we discussed several aspects of the 3D printing industry in a video interview that will be posted on the MCADCafe site very soon.
Among the things we discussed was the recently released the Wohlers Report 2017, his company’s annual detailed analysis of additive manufacturing (AM) and 3D printing worldwide. According to the Report, the AM industry grew by 17.4% in worldwide revenues in 2016, down from 25.9% the year before, according to the new report. Much of the downturn came from declines by the two largest system manufacturers in the business — 3D Systems and Stratasys. Together, they represented $1.31 billion (21.7%) of the $6.063 billion AM industry. If these two companies were excluded from the analysis, the industry would have grown by 24.9%.
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 more than two decades. Over its 22 years of publication, many (including me) have referred to the report as the “bible” of AM and 3D printing—terms that are used interchangeably by the company and industry. I think it easily remains the most comprehensive resource on the topic and market.
Wohlers Report 2017
Wohlers Report 2017
According to Wohlers Report 2017, 97 manufacturers produced and sold industrial additive manufacturing (AM) systems in 2016. This is up from 62 companies in 2015 and 49 in 2014. These manufacturers are providing interesting products and unprecedented competition in the AM industry. This wave of development and commercialization is putting pressure on the established producers of industrial AM systems.
For Wohlers Report 2017, input was collected from 100 service providers, 61 industrial system manufacturers, and 19 producers of third-party materials and low-cost desktop 3D printers.
The Report also includes contributions from 76 experts in 31 countries. No other published analysis of the AM industry is supported by more than two decades of hard data (and the knowledge gained from it) as the basis for computing growth, analyzing trends, and forecasting the future.
Wohlers Report 2017 serves as both an excellent educational and reference tool. It provides an in-depth review and analysis of the industry worldwide. It includes growth, competitive products and services, and the future outlook for the industry. The report covers the technology’s history, applications, processes, materials, and equipment manufacturers. It also thoroughly documents developments in R&D, investment and collaborative activities in government, academia, and industry. The report brings to light the rich range of technologies, markets, and business models that continue to emerge within the industry.

Solid Edge SE10’s Generative Design + Reverse Engineering + 3D Printing/Additive Manufacturing = Siemens Convergent Modeling
Last week at the Siemens PLM Connection 2017, I was introduced to several new products and technologies, and was reintroduced to a product that I had prior experience with, but needed a refresher as to where it stood today — Solid Edge ST10.
The latest release brings just about every aspect of product development forward with new design technology, enhanced fluid flow and heat transfer analysis, and cloud-based collaboration tools. Solid Edge ST10 makes it easier to optimize parts for additive manufacturing (AM) and obtain quotes, material selection and delivery schedules from AM service providers. Newly integrated topology optimization technology, combined with Siemens’ Convergent Modeling technology, improves product design efficiency and the ability to work with imported geometry.
Originally developed and released by Intergraph in 1996 using the ACIS geometric modeling kernel it later changed to the Parasolid kernel. In 1998 it was purchased and further developed by UGS Corp (the purchase date corresponds to the kernel swap).

In an effort to appeal to SMBs with Solid Edge ST10, John Miller, Senior Vice President and General Manager at Siemens PLM Software, said, “Digitalization is leveling the playing field, providing unlimited opportunities for small-to medium-sized businesses to disrupt industry.”

It’s not often (thankfully) that I cover two major conference events in the same week, but this week was exceptional (in a good way) — Siemens PLM Connection and RAPID + TCT 3D Printing & Manufacturing.
Siemens PLM Connection
The Siemens PLM Connection event in Indianapolis was a first timer for me and I got a lot out of it.
The major theme I came away with was Siemens’ push for what it calls the digital enterprise hub based on a digital twin.
There are many definitions of the digital twin, but for Siemens, a digital twin is a set of computer models that provide the means to design, validate and optimize a part, a product, a manufacturing process or a production facility in the virtual world. It does these things fast, accurately and as close as possible to the real thing – the physical counterpart. These digital twins use data from sensors that are installed on physical objects to represent their near real time status, working condition or position.
A deployment of a digital twin includes three pillars: in product design, in manufacturing process planning and in feedback loops.
1. In product design. A digital twin includes all design elements of a product, namely:

Clean up after anything is not usually an especially enjoyable endeavor, even where subtractive or additive manufacturing processes are concerned. This is where post processing comes in.
The Problem with CAD In Subtractive Manufacturing
To cut parts using a CNC cutting machine, it has to be programmed with the path of the desired shape or nest of shapes. Most parts are designed with a CAD program where they are saved in a CAD drawing format, such as DWG, STEP, or several others.
But you can’t just take the CAD file and send it to a cutting machine. It has to be interpreted first, so the CNC on the cutting machine can understand it. The problem with CAD file formats is that:

I spent this week in the beautiful city of Ghent, Belgium for a series of company and product overviews at Bricsys at an event the company called Bricsys Insights.
For me, this was an introduction to and company and product line I had heard about, but didn’t have much knowledge about. This week that all changed for the better.
As a company, Bricsys has taken on several iterations over the years since it was founded in 2002, and has emerged today as a real player in the CAD markets for both architectural and mechanical design applications. The company currently has 130-140 employees, the majority being developers, so it is efficiently run and product focused.

A lot has gone on in the past couple months at metrology giant Hexagon AB, so let’s have a look.
For starters, Hexagon AB, announced recently that it was acquiring MSC Software Corp. for $834 million cash. While not quite as big, the acquisition is Hexagon’s largest deal since it bought Intergraph for $2.1 billion in 2010.
MSC Software is the the company that has brought products that include Nastran, Patran, Marc, and Apex to market. For more than 50 years MSC has been a leading provider of CAE solutions, primarily simulation software for virtual product and manufacturing process development, and was one of the first 10 commercial software companies.
As I noted when the acquisition was first announced, acquiring MSC provides Hexagon with a strong foothold in the competitive simulation/analysis market with MSC’s diverse portfolio of CAE applications.
Hexagon: Shaping Smart Change
As it has with all recent acquisitions, Hexagon plans for MSC to run as an independent business unit within the Hexagon Manufacturing Intelligence (MI) division, that focuses on automotive, aerospace, machinery, consumer electronics, and other discrete manufacturing markets, getting close to offering comprehensive end-to-end solutions in these diverse workflows. About the only link missing is a true CAD component and I can think of several possible targets for closing this gap.
Process-oriented solutions are essential for manufacturers, and MSC’s applications definitely address design and engineering processes through simulation and analysis.
