Last week marked the 50th edition of one of the world’s biggest technology spectacles – CES 2017 – showcasing the connected future of technology. With more than 3,800 exhibiting companies and exhibit space of more than 2.6 million net square feet, CES 2017 hosted some the world’s biggest companies in addition to hosting more than 600 startups. More than 175,000 industry attendees, including 55,000 from outside the U.S., convened in Las Vegas to discover the latest and greatest in many segments of the technology industry.
Probably one of the big trends at CES 2017 was Amazon’s Alexa assistant integrated into all sorts of gadgets everywhere, including cars! Not to be outdone, at this year’s CES, though, no fewer than 56 exhibitors were under the 3D Printing banner – many that you’ve heard of and a few that you probably haven’t. Although there were some basic retreads on previously released products, there were significant developments presented, and the ones that caught our eye were in the areas of materials (metals and ceramics) and affordability (sub-$500 machines).
It’s almost the end of November, so with just over a month left of this year, it’s not too early to start thinking about what we’ll be covering in 2017. The calendar below reflects what we perceive as some of the most important topics today, as well as feedback from our readers and other supporters.

If there ever was a company that has struggled to reinvent and find itself, as well as its former stature in consumer and commercial technology, it’s HP.
There was a time when HP had no equal in several product segments, such as test & measurement, calculators, pocket PCs/personal assistants, etc., but those days are long gone. Sure, the company reigns in printers, and their desktop and mobile workstations are good, but not nearly as compelling as in the good old days.
HP’s reign as the world’s largest manufacturer of personal computers came to an end in the second quarter of 2013. At the time sales figures showed that Chinese PC manufacturer Lenovo shipped more computers during that period than HP, which had held the crown as the largest PC maker since at least 2006.
In an attempt to return to its former glory days, HP split into two public companies with one side focusing on its cloud and enterprise market (Hewlett-Packard Enterprise), and the other on personal systems (computers) and printers (HP Inc.). To make this happen, the company also cut thousands of jobs in the process.
Last month at IMTS 2016 we checked out a lot of new and improved manufacturing technologies, including several innovative developments in 3D printing/additive manufacturing. A couple of the most unique technology introductions were from Stratasys.
The company demonstrated its next-generation manufacturing technologies as part of its Shaping What’s Next vision for manufacturing that builds on its industrial FDM 3D printing expertise in response to the needs of customers’ most challenging applications, addressing manufacturers’ needs to rapidly produce strong parts ranging in size from an automobile armrest to an entire aircraft interior panel.
Stratasys developed two new prototype machines that they called demonstrators to prove their practicality – the Infinite Build 3D Demonstrator and the Robotic Composite 3D Demonstrator.

The Infinite-Build 3D Demonstrator
The Stratasys Infinite-Build 3D Demonstrator was designed to address the requirements of aerospace, automotive and other industries for large, lightweight, thermoplastic parts with predictable mechanical properties. The 3D Demonstrator featured a new approach to FDM extrusion that increases throughput and repeatability. The system also employed a unique “infinite-build” approach, that prints on a vertical plane for parts that are virtually unlimited size in the build direction, such as entire airplane panels.
The Infinite-Build demonstrator is called that because, by flipping the vertical FDM process on its side, “We’re able to print parts in that vertical plane direction essentially as large as we want,” said Rich Garrity, president of Stratasys Americas.
Held every two years at McCormick Place in Chicago, the International Manufacturing Technology Show (IMTS) is the one of the largest (over 110,000 attendees), most comprehensive (~2,400 exhibitors), and longest (six days) manufacturing shows conferences in the world, certainly North America. This year’s event marked IMTS’s 31st edition. First timers and long timers are overwhelmed by the sheer size of this event. At over 1.3 million square feet, you better dress comfortably and prepare for an overload of manufacturing technology sights and sounds.
Because IMTS is so comprehensive and massive, planning is everything, and as you walk around the various pavilions, you start to get a sense of trends and likely future impact of just about all of the technological aspects of design, engineering, and manufacturing.
Below are the major manufacturing trends that I experienced this week. Starting next week I’ll detail what I considered to be the most significant technologies and products showcased at IMTS this time around. Next week, I’ll also go over the major software developments that were introduced — mostly CAM, but some significant stuff.
All 3D printers need host software to function. That’s a given. Host software sends the commands to a 3D printer that tells the printer how to build an object. Most host software communicates with the printer via a wired USB connection. For almost all 3D printers, a computer running the host software must stay tethered to the 3D printer at all times while it is running. Obviously, this is not always a great situation, hence the advantage of being wireless.
There are basically two ways to perform wireless 3D printing. First, a G-code file can be saved onto an SD card using a computer, then the SD card can be transferred to the 3D printer where the print job is initiated via a controller into a 3D printer.
This arrangement allows wireless 3D printing, but it lacks most the advantages of a truly wireless setup. The 3D printer can still be placed away from a work area, but beyond that, using the SD card transfer method is really no different than transferring data over a cable. The second way to do (truly) wireless 3D printing is by running the host software on a small embedded device, like the Raspberry Pi, that is connected to the 3D printer.
Which Is Better, OctoPrint or AstroPrint?
This is analogous to using a dedicated computer for 3D printing that stays connected to the printer at all times. But, instead of using a computer for this purpose, the host software can be run on something, such as a Raspberry Pi, which is just powerful enough to run the software.
The two most popular host software packages developed for wireless 3D printing are OctoPrint and AstroPrint. AstroPrint is, in fact, based on OctoPrint, and claims to have an optimized codebase for running on embedded computers. The AstroPrint team has made changes and additions to the software, making the two host software offerings quite a bit different in many ways.
While OctoPrint and AstroPrint do share some similarities, they are also different, primarily with regard to their intended users.
With all the fanfare that took place a couple years ago with the launch of cloud-based Onshape, we thought we’d weigh in with partner Geometric’s announcement of its STL Workshop.
Onshape is by no means the first cloud-based/mobile CAD application. It was and still is, however, a unique true cloud-based technology and not a desktop/cloud hybrid.
Onshape began with what was one of the best and worst kept secrets in the engineering software arena. Worst, because even early on, it was evident that the technology would be cloud based, even if virtually no details were disclosed. Best, because virtually no details were disclosed, and that just added to the anticipation for the official launch of Onshape.
One of the inherent advantages that Onshape has always had is the fact that it was created from scratch by a team used to creating things from scratch with no legacy baggage to overcome and work around. Of course, the development team has not done everything themselves, because Onshape includes software components from Siemens PLM (Parasolid; ironically the same modeling kernel used by SolidWorks) and D-Cubed. This component licensing has let the Onshape team focus its efforts on what it does best.
Shapeways, a leading 3D printing service and marketplace for consumers, announced a collaboration with HP Inc. to help drive HP’s Jet Fusion 3D Printer. Shapeways said it is the first company to receive an early prototype unit in its Eindhoven, Netherlands factory and is working closely with HP. Once publicly available sometime later this year, Shapeways hopes the new commercial HP offering will provide its 3D community with a superior quality black nylon material that will 3D print in greater detail, with a faster lead time, and at a lower cost than current dyed nylons.
Shapeways produces roughly 3,000 unique products every day and over 1 million unique products annually.
“We chose to work with Shapeways because they are the leading authority in bringing creative ideas to life and are the largest consumer 3D printing portal, with 3,000 products made every day,” said Stephen Nigro, president of HP’s 3D printing business. “The HP Jet Fusion 3D Printing Solution will enable Shapeways to bring high quality parts up to 10 times faster than before for lower cost.”

According to Shapeways, in addition to offering superior quality, this new technology could potentially reduce standard shipping from the current seven business days to next day delivery. (more…)
The notion of a 3D printer in every home has received a lot of attention in the past few years, and sales of relatively low cost 3D printers have skyrocketed.
But why? For a process and capability that was supposed to be ubiquitous and necessary for every home? Really? The machines may be relatively inexpensive, but how many parts are you truly going to want to ultimately design and produce? Then there are material, size/volume, and physical characteristic, and quality limitations. The machines can also be fickle to set up and maintain. I suspect that after an initial period of excitement and promise, a lot of early-purchase 3D printers are now sitting idle and collecting dust. (more…)
Wohlers Associates, Inc., recently released the Wohlers Report 2016, the company’s annual detailed analysis of additive manufacturing (AM) and 3D printing worldwide. According to the Report, interest in 3D printing again reached an unprecedented level and exceeded $5.1 billion last year, as well as growing by $1 billion for the second consecutive year.
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 21 years of publication, many (including me) 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. I think it easily remains the most comprehensive resource on the topic and market. (more…)
