3D printing may sharply alter production mode, says HP executive

Sammi Huang, Taipei; Willis Ke, DIGITIMES [Wednesday 5 July 2017]
digitimes.com

Extensive application of 3D printing technologies is very likely to trigger a drastic change in the manufacturing sector in the foreseeable future, with customized production of personalized products to emerge as a new mode beyond mass production of uniform products. This may make the entry threshold into manufacturing operations almost disappear, allowing anyone to become a manufacturer, according to Ramon Pastor, vice president and general manager of HP Multi Jet Fusion 3D printing solutions business.

This is a future world HP is actively pursuing with the application of its newly developed Multi Jet Fusion 3D Solutions, said Pastor in an interview by Digitimes, despite the fact that in its first stage of application, 3D printing can only help to make production become more efficient in the Internet era when product design, production and consuming are carried out separately.

HP has set 3D printing solutions as one of the crucial engines driving its business growth, incorporating a vision of eventually reshaping the US$12 trillion manufacturing sector into a fully digitalized one, though it's a long journey to take, according to Pastor.

Global 3D market scale estimated at US$18 billion in 2021

The global 3D market scale, now estimated at US$6 billion, will be expanding at a sharp annual pace of 30% to reach US$18 billion by the end of 2021, Pastor said, adding that the majority of 3D printing business opportunities are mainly seen in the plastics industry. In this regard, HP is expected to command a high market share, at 75%, with its jet fusion printing technology.

Against the huge global manufacturing scale of US$12 trillion, the existing 3D market scale is really quite small. This is due partly to the current 3D printing technologies having not matured enough to achieve precision printing, and partly to the high costs required for the technologies, according to Pastor.

These two unfavorable factors have undermined 3D printing applications, but can be addressed with Multi Jet Fusion 3D printing solutions launched by HP, widely seen as a major technical breakthrough, Pastor claimed.

Versatile Multi Jet Fusion 3D printer

Since HP debuted its Multi Jet Fusion 3D printer one year ago, the new product has been well received worldwide as it can cut 3D printing cost by 50% and its printing speed is 10 times that of general 3D printers, according to Pastor.

With high-caliber parts and components, HP Multi Jet 3D printers boast high printing capacity and are totally applicable to production lines of the manufacturing sector, Pastor said.

He continued that HP has forged ties with partners in different fields, such as BMW, Johnson & Johnson, Nike, Autodesk and Siemens, to jointly develop materials and commercial systems suitable for the fields, aiming to better popularize 3D printing and facilitate market expansion.

Furthermore, HP has set up an open-type materials and applications experiment platform to develop diverse printing materials in collaboration with more than 50 suppliers of printing materials, including Germany's BASF, Henkel and Evonik and France's Arkema.

Just a few months ago, Pastor said, HP debuted the industry's first set of MDK (3D Materials Development Kit) in conjunction with the launch of brand-new printing materials. This is one of the firm's key business strategies, based on the belief that 3D printing materials will determine the effect of 3D printing solutions.

HP has sustained a consistent value proposition: the availability of powerful service and support systems, which can be incorporated into the 3D printer market to help expand the firm's share of the market, Pastor noted.

3D voxel printing

He went on to highlight the firm's Jet Fusion printing technology, saying that the unique technology can conduct 3D voxel printing, helping to change the performance of materials, and boost the economy, recyclability and efficiency of printing materials to reduce overall costs involved.

As of December 2016, HP's Multi Jet Fusion 3D printers had helped customers turn out over 500,000 printing pieces within months after the new solutions were debuted.

In terms of global marketing, HP has established 3D distribution networks in North America and Europe, and is moving to partner with over 40 distributors in China and other Asian countries.

In addition, HP has operated many exhibition and experience centers around the world to allow customers to test printing applications.

Talking about HP's future development in 3D printers, Pastor said in line with the advent of the Internet of Things (IoT), the company will move to change and upgrade the performance of voxel printing materials. A voxel is a 21x21x80um cube, and the performance of voxel can be changed based on whether extensibility, intensity, heat conductibility or electricity conductibility of the printing materials is needed.

3D scanning using a dip scanner. The object is dipped using a robot arm in a bath of water (left), acquiring a dip transform. The quality of the reconstruction is improving as the number of dipping orientations is increased (from left to right) [*Corresponding author]







Abstract

The paper presents a novel three-dimensional shape acquisition and reconstruction method based on the well-known Archimedes equality between fluid displacement and the submerged volume. By repeatedly dipping a shape in liquid in different orientations and measuring its volume displacement, we generate the dip transform: a novel volumetric shape representation that characterizes the object’s surface. The key feature of our method is that it employs fluid displacements as the shape sensor. Unlike optical sensors, the liquid has no line-of-sight requirements, it penetrates cavities and hidden parts of the object, as well as transparent and glossy materials, thus bypassing all visibility and optical limitations of conventional scanning devices. Our new scanning approach is implemented using a dipping robot arm and a bath of water, via which it measures the water elevation. We show results of reconstructing complex 3D shapes and evaluate the quality of the reconstruction with respect to the number of dips.

Desktop Metal gets $115 million in funding to deliver metal 3D printing for manufacturing




Desktop Metal has already earned a number of fans with its 3D printed metal technology — Lowe’s, Caterpillar and BMW were all among its earliest clients. As first noted by CNBC, the Massachusetts-based startup is also getting some healthy monetary support, adding $115 million of venture funds to its coffers this week. The Series D features a number of high profile names, including New Enterprise Associates, GV (formerly Google Ventures), GE Ventures, Future Fund and Techtronic Industries, the holdings company that owns Hoover U.S. and Dirt Devil.

Founded in 2013 by four MIT professors, Desktop Metal isn’t the first company to bring metal 3D printing to market, but it’s probably the most efficient. By its own measure, the company’s machines are able to print objects at up to 100-times the speed of their competitors. That’s good news for those clients using Studio, the prototyping machine the company announced last year — but even more useful for those planning to use the upcoming Production, a system designed to bring the technology to manufacturing.





Speed has been of the main bottlenecks in mainstreaming 3D printing for manufacturing — metal or otherwise. The Production system isn’t going to replace wide scale manufacturing any time soon, but it will make it a more realistic possibility for smaller speciality parts, with its ability to print 500 cubic inches of metal per hour. According to CEO Ric Fulop, that works out to millions of parts per year for a given machine.

“You don’t need tooling,” he tells TechCrunch. “You can make short runs of production with basically no tooling costs. You can change your design and iterate very fast. And now you can make shapes you couldn’t make any other way, so now you can lightweight a part and work with alloys that are very, very hard, with very extreme properties.”

The list of companies that have embraced the $50,000+ Surface is pretty diverse. Automakers like BMW are using it to prototype products, and the local robotics community has also been extremely excited about the device’s ability to print in a broad range of alloys. For smaller companies without access to big machining warehouses, prototyping with metal is a pretty big pain point.

“One of the benefits for this technology for robotics is that you’re able to do lots of turns,” says Fulop. “Unless you’re iRobot with the Roomba, you’re making a lot of one-off changes to your product.”

Desktop Metal is still pretty small, at around 150 people — mostly engineers, according to Fulop. Along with R&D, this latest funding round will go a ways toward increasing that staff and reach, with plans to extend to more markets, including Europe and Asia.

Overview Desktop Metal is reinventing the way design and manufacturing teams produce and 3D print metal parts - from prototyping through mass production. They team is built around the disciplines of materials science, hardware and software engineering, and design. They have raised $97 million in equity funding with investment from technology leaders including Google, BMW, Lowe’s, and Kleiner Perkins Caufield …Location

Synthetic muscle breakthrough could lead to 'lifelike' robots

Researchers claim it's the closest artificial material equivalent to a natural muscle.

_____________________

A breakthrough in soft robotics means scientists are now one step closer to creating lifelike machines. Researchers at Columbia Engineering have developed a 3D printed synthetic tissue that can act as active muscle. The material, which can push, pull, bend, and twist (thanks to its use of silicone rubber and ethanol-dispensing micro-bubbles) is also capable of carrying 1,000 times its own weight. Not only could the invention result in super-strong machines (like a Terminator that works in manufacturing), but it will also release soft robots from their current shackles.

You see, synthetic muscle tech is presently reliant on tethered external compressors or high voltage equipment. But, robots fitted with this new tissue could theoretically be freed up to move around like humans, enabling them to better grip and pick up objects. Which is a big deal, because the plan is to eventually get these bots to help with non-invasive surgeries and to care for the elderly -- among other tasks.



The researchers are touting the material as the first synthetic muscle that can withstand both high-actuation stress and high strain. "We've been making great strides toward making robots minds, but robot bodies are still primitive," said lead scientist Hod Lipson. "This is a big piece of the puzzle and, like biology, the new actuator can be shaped and reshaped a thousand ways. We've overcome one of the final barriers to making lifelike robots."

After 3D printing it into the desired shape, the team electrically actuated the artificial muscle using a thin resistive wire and low-power (8V). They then tested it in a variety of robotic applications, where it demonstrated significant expansion-contraction ability. The researchers claim the synthetic tissue is also capable of expanding up to 900 percent when electrically heated to 80°C.

Building on their initial findings, the team plans to incorporate conductive materials to replace the need for the connecting wire. Further down the line, they intend to combine it with artificial intelligence that can learn to control the muscle, resulting in (they hope) "natural" movement.

Xian Y-20
This cargo aircraft is used by the Chinese military in order to ferry goods and soldiers to anywhere in China at a moment’s notice. Perhaps most interestingly, many of the plane’s parts were created using a 3D printer, thereby drastically lowering the cost of production. The plane can carry up to 66 tons, and when filled with troops, has a range of 6,200 miles, enabling this plane to reach anywhere in Asia.

lots of material on SSYS investment in Desktop Metal. New technology
much faster. I can not find anywhere what their $14M in October 2015 got them.
True, DDD is working on its own answer to faster metal production.

If anyone can find the answer to the above that would be excellent.
Thanks Dave
