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…)
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…)
For as long as I can remember, HP has produced an incredible range of products for science, engineering, and consumer customers. More recently the company has had a huge presence in computers and 2D printers.
Now, HP has vision for 3D printing for manufacturing parts on a relatively economical machine it calls the Multi Jet Fusion (MJF) 3D printer. The company claims these parts will have similar quality and characteristics as injection-molded parts, and will print at speeds that HP claims to be 10x compared to similar competing technologies. More about these claims to follow.
With multitasking an increasing fact of life for us all, it’s no surprise that machine tools continue to evolve into increasingly multifunction machine platforms, as well.
Let’s be honest, though, multifunction machines are not exactly new. For example, machines with processes that work together providing several functions, such as milling, turning, drilling, tapping, measurement, and EDM have been around for a number of years as requirements have changed.
I’ve also seen a number of interesting things on the exhibit floors at manufacturing trade shows, such as RAPID and IMTS, that employ traditional multifunctional capabilities, but have been most intrigued by a new emerging class of hybrid 3D printers that employ both additive manufacturing (AM) and subtractive (conventional machining) methods. Some of these innovative hybrid machines follow.

Today, 3D printing is relatively well established, with an ever-increasing selection of printers available, ranging from low-cost personal/desktop 3D units for home to the larger and much more capable industrial-strength printers.
The technology itself has also evolved and is now being implemented in a wide range of industries from automotive to aerospace, construction, health, food, and many others.
By now most of us are familiar with 3D, but for the past couple of years there has been increasing chatter about 4D printing. So what is 4D printing?
He described 4D printed objects as 3D-printed objects that reshape themselves or self-assemble over time, depending on the environment they’re in. In other words, the 4th dimension is time and/or environmental conditions.
Tibbits is said to be working with GEOSyntec to design 4D printed water pipes. As the scale and reach of the technology increases, applications in the military (no surprise here) and construction industries are likely to materialize.
Shapeshifting: 3D printed materials that change shape over time.
Dr Dan Raviv, postdoctoral fellow at MIT, believes that 4D printing may be used in a wide range of applications such as home appliances, childcare products, or even clothes and footwear that optimize their form and function by reacting to changes in the environment.
New York’s Museum of Modern Art (MoMA) recently acquired a 4D-printed dress which designers were able to print using a powder-based nylon material, and made the dress out of thousands of interlocking pieces.
The pace at which 3D printing has evolved in various industries is impressive, but the technology is still too slow for mass manufacturing, and precision and repeatability must still improve for fabrication of structural components.
The power to offer customized products that are manufactured closer to their point of consumption certainly makes the technology appealing to both providers and consumers. It’s a growing market, but there’s still a lot work to be done – particularly around process speed, product size, and the variety of materials that can be used with the technology.
In the near future, 4D printing could be used in space. For example, an improved 3D printing process using materials that could self-assemble (the next topic below) was used to fabricate components on-site and on-demand for astronauts during a space mission.
A recent study reported in The Conversation has shown that high frequency vibrations can cause bricks to self-assemble into a larger 3D object, a finding that may one day help reduce the need for factory assembly lines.
The findings, published recently in the journal, Scientific Reports, signal a key advancement in programmable self-assembly, which was previously thought to only be possible using one-dimensional or two-dimensional objects.
The research team, led by Dr Ido Bachelet from the Institute for Nanotechnology and Advanced Materials at Bar-Ilan University in Israel, used an algorithm from the Computational Geometry Algorithm Library (CGAL) as part of a design that allowed 18 tetrahedral bricks to self-assemble into a larger 3D cylinder.
The following video shows blocks in the self-assembly process. Two sets of the object (36 bricks) were inserted in the chamber and after 2.5 hours in a constant speed of 320 rpm one set was assembled. The video doesn’t contain the whole, but portions of it.
The Basic Self-Assembly Process
“Assembly rules are encoded by topographic cues imprinted on brick faces while attraction between bricks is provided by embedded magnets,” the researchers said in their paper. “The bricks can then be mixed in a container and agitated, leading to properly assembled objects at high yields and zero errors.
“Improved designs inspired by our system could lead to successful implementation of self-assembly at the macro-scale, allowing rapid, on-demand fabrication of objects without the need for assembly lines.”
The ability for life to self-assemble is something that continues to puzzle scientists. For example, proteins, viruses, living cells and multi-cellular organisms are all examples of systems in which parts are bonded to each other through attraction to form a structure or pattern.
Hamza Bendemra, a Research Engineer at the Australian National University, who was not involved in the study, said the research of 3D printed assemblies is remarkable.
“The algorithm was inspired by the molecular assembly of the DNA,” he said. But he added that more research was needed to address challenges of time, space and safety for the model to be more efficient at forming and remaining together.
“In the study, a two-brick assembly took less than a minute to self-assemble. However, an 18-piece assembly required over two hours to perform the same feat.”
“The components are subject to high vibrations and collide over and over again until they fit in the right combination. It would be a challenge to implement such a method with materials with low strength and poor impact tolerance without causing damage.”
The next step in developing this concept for construction and manufacturing industries is to use both magnetic forces and adhesives to ensure the assembly stays in place.
Bendemra agreed, saying that “the researchers did a great job at adding topographic cues to ensure a unique combination only would lead to the pieces locking in. Their footage clearly shows that pieces that collide in a non-desired formation detach until they lock-in as planned.”
“The number of pieces involved in the assembly and the nature of the materials being used (including the magnet) in more complex assemblies could limit the use of such a method.”
Without a doubt, one of the biggest developments in the MCAD world in the past few years has been 3D printing (also known as additive manufacturing). Until relatively recently, though, the cost of the 3D printing machines was cost prohibitive for all but large companies. To a large extent, costs have been plummeting, but there are machines that cost more than a million dollars. However, that is changing with the advent of relatively low-cost desktop 3D printers.
3D printers sound cool, and to a large extent they are. But, before running out to buy one, there are a few things to keep in mind. Currently, a machine will set you back $500 to $5,000, plus $40 to $100 for a roll of plastic filament (think Weed Wacker) for producing parts. Also keep in mind that producing one small object could take hours, and end up costing much more than buying it. Don’t forget, too, that you need some technical know-how to make it all work, including how to create a solid model with a CAD tool. As I have maintained for some time, with all the online 3D printing services that are available, why buy when you can rent. Check out my blog post on this sentiment from last year entitled, “3D Printing Goes Retail: Why Buy When You Can Rent?”
That’s why I have said that the first low-cost devices were more fun than functional, and appealed to DIYers, hobbyists, and early adopters. All that is changing as the technology matures, prices come down, more materials become available, and part quality vastly improves.
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).
We’re heading to Long Beach, California next week to participate in one of SME’s marquee events — RAPID 2015.
I’ll be at the conference all week taking in the keynotes, new hardware and software products and service announcements, as well as sitting in on a few technical sessions.
This is an especially pivotal year in the evolution of 3D printing as it strives to get to the next level with higher quality parts, lower cost materials, and greater presence in manufacturing direct part production.
I’ll be hitting the floor running early Tuesday morning and will be Tweeting throughout the event, as well as posting blogs at the end of each day.
If you’re going to RAPID 2015 in Long Beach, feel free to contact me at 719.221.1867 or firstname.lastname@example.org and let’s meet up for discussing the latest technologies, trends, rumors, etc.
This week Sigma Labs a developer of advanced, in process, non-destructive quality inspection systems for metal-based additive manufacturing and other advanced manufacturing technologies, announced that it has been granted its first contract, worth approximately $500,000, from GE Aviation. The company was previously announced as a member of the winning team of companies and universities awarded an “America Makes” additive manufacturing (AM) research project. This project is funded by the National Additive Manufacturing Innovation Institute (NAMII) and covers Sigma Labs’ proprietary In-Process Quality Assurance (IPQA) software for advanced AM monitoring.
The contract will implement the Sigma Labs’ PrintRite3D technology across multiple platforms, specifically those requiring high-volume, high-quality aerospace components. Over the next 18 months Sigma Labs is expected to deploy a total of three systems – one each to GE Aviation and to other team members Honeywell and Aerojet Rocketdyne.
The Story Behind Sigma Labs
“We are very pleased to announce this first contract under our previously-announced award with NAMII,” said Mark Cola, President and Chief Executive Officer of Sigma Labs. “Working with some of the best known companies in the industry, including GE Aviation and Honeywell, we will use this project to further demonstrate our PrintRite3D technology and provide for additional data collection. We believe awards such as this open up the way for business development opportunities and, at the same time, strengthen Sigma Labs’ position in the nascent yet rapidly-growing AM space.”
Sigma Labs through its wholly-owned subsidiary, B6 Sigma, develops and engineers advanced, in-process, non-destructive quality inspection systems for organizations worldwide seeking solutions for metal-based additive manufacturing or 3D printing, and other advanced manufacturing technologies.
An organization that we know quite well, Wohlers Associates, Inc., recently released the Wohlers Report 2014, 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 $3 billion milestone. The phenomenal attention to AM began in 2012, and it was sudden. As Greg Morris of GE Aviation said, “It was like someone flipped a switch.” Governments, major corporations, investors, and the mainstream media developed an insatiable appetite for additive manufacturing, and it occurred quickly.
Wohlers Report 2014
As it has from the beginning, Wohlers Report 2014 covers virtually every aspect of additive manufacturing, including its history, applications, underlying technologies, processes, manufacturers, and materials. It documents significant developments that have occurred in the past year, R&D and collaboration activities in government, academia, industry, and summarizes the worldwide state of the industry. This edition is the report’s 19th consecutive year of publication.
Wohlers Associates believes the industry will continue strong growth over the next several years. It will be fueled by sales of under $5,000 “personal” 3D printers, as well as the expanded use of the technology for the production of parts, especially metal, that go into final products. “The industry is experiencing change that we have not seen in 20+ years of tracking it,” stated Tim Caffrey, senior consultant at the company and one of two principal authors of the new report. He added, “What’s most exciting is that we have barely scratched the surface of what’s possible.”
