U.S. Bank’s latest quarterly Freight Payment Index for fourth quarter describes a positive economic environment for the U.S to end 2018 but it also points to one of a possible slow down as we progress into 2019. The U.S. Bank National Shipment and Spend Indices both increased from the third to fourth quarters, with the Spend Index increasing 7.2% to a record high. Meanwhile, the National Shipment Index rose 1.7% from the third quarter.
Indeed, despite the positive end to 2018 and midway into the first quarter of 2019, the year’s outlook is even murkier than in December when the U.S. Bank noted concern for a possible slow down this year. So many unknowns on the economic stage as one wonders the effects of additional tariffs that are expected to increase in March, the lack of UK government guidance as Brexit looms with just a month to go for the final break, China’s economic downturn and a growing concern of a global recession.
The Refabricator system by the US-based aerospace company Tethers Unlimited Inc. (TUI) has been installed on the International Space Station (ISS). The integrated 3D printer and plastic recycler was launched into space in November last year.
The CEO of TUI Rob Hoyt said that he was “incredibly proud and thankful for the hard work put in by our team, the astronauts, and the NASA In Space Manufacturing Team to get the Refabricator all the way to installation aboard the space station.”
AM is surrounded by much hype, but are you getting the whole story?
Five years ago, Hod Lipson and Melba Kurman gave us Fabricated: The New World of 3D Printing,1 helping to both create and ride a wave of enthusiasm for 3D printing. This enthusiasm, combined with the infusion of U.S. government funding and the expiration of key patents, prompted many to buy a 3D printer for the kids and make stock investments in rising star companies.
Along with their book, Lipson and Kurman gave us the 10 Principles of 3D Printing as a roadmap into the future to explain why 3D printing will disrupt manufacturing and product design. I bought and read the book and enjoyed it. I get that “no one wants to follow a small dream,” but as a process engineer with a background in advanced materials, digital design, and manufacturing, I knew it was not that easy.
Demonstrating lighting speed 3D printing will inevitably get a lot of Youtube hits, but where does speed really matter? If you are able to make Eiffel tower miniatures at super fast rates, how would the entire logistics, inventory, distribution etc. compare to how a Chinese factory is already doing it?
I use this as demo example to demonstrate the clear challenge most companies in the 3D/AM space have, which is being able to come up with creative and truly business driven applications for their technology. If the applications were known, the demo parts would reflect that knowledge.
If you do it in your garage, it’s “3D printing”. If it’s used to build a car, it’s “additive manufacturing”? Where’s line between these two terms? Let’s see if we can’t find it.
Are “3D printing” and “additive manufacturing” (AM) the same thing? In general, we know that terms stretch over time to include more than just their default meanings. Most of us carry digital entertainment supercomputers around in our pockets, and call them “phones”.
Whatever the name, new ways of fabricating directly from bytes to stuff are radically changing the what, where, how, and when of making objects. What roles, then, do the two terms “additive manufacturing” and “3D printing” play in describing new ways of making?
Frustrated by the unresponsiveness of traditional supply chains, Marines from the 29 Palms base generated the concept of converting standard utility vehicles into customizable transport suited for a diverse range of missions.
The market for self-assembling parts is already expected to exceed $64 million.
The days when 3D printing was simply dreamed about are far behind us. Today, the process of creating a three-dimensional object via successive layers of materials is a mainstream activity—from customized medical devices and prosthetics to conventional household products, and even industrial buildings. It’s projected that by 2030, nearly a quarter of Dubai’s buildings will be 3D-printed.
A new 3D printing technique that uses light to produce complex shapes from a vat of liquid resin is up to 100 times faster than conventional 3D printing processes, claim its developers at the University of Michigan.
The method – which uses two lights to control where a curable liquid resin hardens and solidifies and where it stays fluid – has so far been used to print a variety of complex three dimensional demonstration shapes including a lattice, a toy boat and a block letter M.
The group claims that the technique overcomes the limitations of earlier so-called vat-printing efforts, which encountered problems with the resin solidifying on the window that the light shines through, stopping the print job just as it gets started.
3D printing has come a long way from its origins in the 1980s, with a brief entry into the consumer space galvanizing its growth in the earlier part of the decade. Now, it seems as though mass production with additive manufacturing (AM) technology is just around the corner, as a number of companies introduce methods for batch 3D printing.
To learn how the AM space will change in the next year, engineering.com got feedback from several experts in the space, including those from exciting new startups that will break onto the scene in 2019.
