3D printing technology news

Just came across this over on Slashdot:

Foster + Partners works with European Space Agency to 3D print structures on the moon


Foster + Partners is part of a consortium set up by the ESA to explore the possibilities of 3D printing to construct lunar habitations. Addressing the challenges of transporting materials to the moon, the study is investigating the use of lunar soil, known as regolith, as building matter.

The practice has designed a lunar base to house four people, which can offer protection from meteorites, gamma radiation and high temperature fluctuations. The base is first unfolded from a tubular module that can be transported by space rocket. An inflatable dome then extends from one end of this cylinder to provide a support structure for construction. Layers of regolith are then built up over the dome by a robot-operated 3D printer to create a protective shell.

To ensure strength while keeping the amount of binding “ink” to a minimum, the shell is made up of a hollow closed cellular structure similar to foam. The geometry of the structure was designed by Foster + Partners in collaboration with consortium partners – it is groundbreaking in demonstrating the potential of 3D printing to create structures that are close to natural biological systems.

Simulated lunar soil has been used to create a 1.5 tonne mockup and 3D printing tests have been undertaken at a smaller scale in a vacuum chamber to echo lunar conditions. The planned site for the base is at the moon’s southern pole, where there is near perpetual sunlight on the horizon.

The consortium includes Italian space engineering firm Alta SpA, working with Pisa-based engineering university Scuola Superiore Sant’Anna. Monolite UK supplied the D-Shape™ printer and developed a European source for lunar regolith stimulant, which has been used for printing all samples and demonstrators.

Xavier De Kestelier, Partner, Foster + Partners Specialist Modelling Group:
“As a practice, we are used to designing for extreme climates on earth and exploiting the environmental benefits of using local, sustainable materials – our lunar habitation follows a similar logic. It has been a fascinating and unique design process, which has been driven by the possibilities inherent in the material. We look forward to working with ESA and our consortium partners on future research projects.”

3D printing is now the new magic space technology. It is showing up everywhere in space articles and startups now. Lots of people are making extravagant claims for it. They think that it makes everything possible in space. That misses a number of key points. For starters, it hasn't been proven in a space environment. And it also requires raw materials that will have to be either delivered (launched) or processed in situ.

Everybody likes to wave their magic wand, yell "Expecto petronas!" and assume that a 3D printer will simply build whatever they want wherever they want it.

I did read it. Still hasn't been proven. Like so many things in spaceflight, people talk about proposed technologies in the past or current tense, as if they already exist and have already demonstrated their capabilities. Thus all you need to do is launch a payload powered by VASIMR atop a Falcon 9 Heavy and land it on Mars with the Red Dragon...

In the case of 3D printing I see both front end and back end issues--yes, you have to get the 3D printer to work, but many of these proposals assume that it's easy to get the raw materials. I've been to AIAA sessions where they discussed resource extraction at the Moon or Mars and it doesn't sound easy, but then I read stuff on the internets where people simply brush that aside. "All you have to do is mine the materials from the regolith..."

In order for a technology to be proven, somebody has to prove it. This is what ESA and Foster are doing, so IMO it's unfair to rag on them for talking about 3D printing.

Some hype in this article as well: http://www.wired.com/design/2013/02/3-d-printing-on-the-moon/

However, from a 2011 link within the article:



Quote
USC Professors Behrokh Khoshnevis (Engineering), Anders Carlson (Architecture), Neil Leach (Architecture) and Madhu Thangavelu (Astronautics) have completed their first visualization for their NASA research grant into the potential use of Contour Crafting robotic fabrication technology to build structures on the Moon. The image here shows a storage space being constructed by a Contour Crafting robot housed on a version of the Athlete rover developed by the Jet Propulsion Laboratory in Pasadena. The robot prints the structure layer by layer using lunar concrete composed of regolith from the surface of the Moon. Contour Crafting was invented originally for use on earth by Behrokh Khoshnevis at USC, whose alumni include Neil Armstrong, the first person to walk on the Moon. It was recently voted one of the top 15 innovations most likely to change the World. The question now being addressed is how it will change the Moon. [Visualization by Behnaz Farahi and Connor Wingfield.]

...The two issues I don't see being resolved in this study are:


1) Much of how 3D printing works has been developed and tested based on the "bath", "goop" or "powder" is layered under 1G conditions. Back when the "green liquid/gel meets laser" method was king - circa 1994-1995 or thereabouts - the engineers in the proto fab labs locally were doing some back-of-the-barnap number crunching during a tech fair luncheon, and they figured that if you thickened the gel, this method would work fairly well in 1/6G. But a couple of the ME guys were claiming that the powder method would produce solids with a more "gossamer", weaker structure to them because there was less weight to hold one layer down on top of the next as it was being created. There was some issue of settling that was required for a sturdier structure. The current inkjet "goop" process that appears to be the defacto standard for low to middle-end 3D printers would most likely suffer from the same problems.


...The only way to know for certain would be to actually conduct tests on, say, a MakeBot 3D printer in the worst case scenario, sending one up on a Dragon and having it reproduce itself, then leaving the replicant on ISS for them to conduct their own tests with - probably to produce temporary replacement solids until the actual uberoverpriced replacements can be sent up on the next Dragon/Soyuz.


2) It also doesn't address the most important element of any printer, regardless of substance being used to print with: will this wind up being a case of where it's cheaper to send up another Lunar Printer Module when the cartridges run out, or will NASA be locked into a contract where they have to purchase factory issued refills that cost more than a new LPM?  :P :P :P :P :P

Not that far off topic, I would think - Foster is perhaps the architect with the greatest appreciation of aerospace technology and engineering, making real as opposed to cosmetic use of it in his firm's designs.  He's a qualified pilot, was a protege of Buckminster Fuller and once said that the greatest example of twentieth century architecture was the Boeing 747.

The Hangar Terminal Facility at Spaceport America is a Foster + Partners project.

On a related note, there is the SpiderFab robot: http://www.dvice.com/2013-8-30/nasa-wants-build-giant-spacecraft-3d-printing-spiders


...Ah. Is *this* the "sekret projekt" that Blackstar's been hinting about recently? It should be interesting to see how well this concept works, as some 3D printing techniques actually -need- the pull of gravity to keep things in place as each layer is squirted/sprayed on. At the same time, I'm also pretty curious as to what sort of resin/composite is going to be used, and how that material compares to any similar sample materials that were flown on LDEF. IIRC, some "plastigoop"-like materials tend to dissolve after an unacceptably short time exposed to vacuum and those nasty solar wind particles.

 3D printing has been in the news a bit this past week, although they are all variations on the same story.

Amaze project aims to take 3D printing 'into metal age'
The European Space Agency has unveiled plans to "take 3D printing into the metal age" by building parts for jets, spacecraft and fusion projects.http://www.bbc.co.uk/news/science-environment-24528306

AMAZING FUTURE
A metal 3D-printing revolution is entering space. AMAZE is a recently announced project that aims to perfect the printing of space-quality metal components on Earth and beyond within five years. 3D printing builds a solid object from a series of layers, each one printed on top of the last. This ‘additive manufacturing’ technique produces very complex structures with minimal waste and maximum flexibility. http://www.esa.int/Our_Activities/Human_Spaceflight/Highlights/Amazing_future 

3D PRINTING FOR SPACE: THE ADDITIVE REVOLUTION

3D printing is getting ready to revolutionise space travel. ESA is paving the way for 3D-printed metals to build high-quality, intricate shapes with massive cost savings.

...One interesting use I'm already hearing for this 3D Metal process is a new way of applying aluminum siding to a house. One particular variation calls for the house to not be painted at all, but simply sealcoated with the Al print. Would be interesting to see a long-term environmental wear-n-tear study, especially in areas where the humidity is generally high, or termites tend to be somewhat in abundance.

I didn't spot this video in the previous contributions.  This technology generates net shape parts that require significant finish machining so it is a bit different.  On the other hand, it works with metals that are used for high load/heat environments.  The sponsor list at the back end ties the work directly to defense/aerospace.

A new wrinkle in 3D printing where continuous laser polymerization of resin is modulated by inhibiting the reaction with Oxygen.  The result is 100x faster part production.  The company is still in start up phase but is attracting lots of venture capital and may become one of the big players in the field.

3-D Printing Holds Huge Promise for AFMC

 —John A. Tirpak9/17/2015

​Additive, or 3-D, printing is one of those technologies with “huge implications” for the Air Force’s ability to affordably sustain its forces, Air Force Materiel Command chief Gen. Ellen Pawlikowski said Tuesday at ASC15. Especially given the fact that so many USAF platforms are old, and for which parts are no longer available, 3-D could be a windfall development, she said. She noted that a B-52 component long out of production—the absence of which would ground the airplane—was digitally mapped by one of her engineers and a usable replacement printed “with a three-day delivery,” she said. Moreover, the component had more than 100 parts, but the printed version was a single part. The ramifications are that whole warehouses of parts could be eliminated, creating spares only when needed. “All you need is to keep the data file,” she said. She pegged the technology right after directed energy, autonomy, and hypersonics as the biggest “game changers” coming in the next decade.

MIT 3D printed glass.  Looks like extruded glass laying rather than 3D printing with a laser heating a bed of powderized glass.  Not sure if this will go anywhere unless they can get the extrusion shape to allow contiguous patterns with no corrugations.

I'm waiting for the tech to become precise enough with enough strength to allow the large scale 3D printing of aircraft components; specifically aluminum alloys.

Can we say 3D Printed B-32 dominator?  :o

It already is for many parts (e.g. major structural components).  The problems are that aerospace is at the same both leading edge and ultra conservative when it comes to adopting such things - everyone wants to ensure it will be perfect and risk free.  The other issue affecting this is the need for large scale printers.  I have seen some with a 3 - 5 m working bed but I'm not sure if anyone has readily used them or whether they have gone bigger.

One also has to remember that most printed metal parts will still require some form of finish machining therefore one also needs the associated large scale CNC mills and also dimensional verification equipment.

One final point:  3D printing/Additive manufacturing will only ever get into its stride when we start designing parts that can only be 3D printed.  Continually using it to look at parts that can already be conventionally machined or similar is a waste.

As long as the apparatchiks at the State Department deem it so, maybe the federal courts in their infinite wisdom will next recognize the danger in exporting the CAD designs for the wheel?

As stated, this information has been widely available all over the globe (electronically) for at least a decade or more. The genie is out of the bottle.

The dissenting judge lays it out quite well and her full dissent is worth reading. This is yet another attempt by the Obama Administration (and its political allies) to harm domestic firearms makers, designers, and hobbyists by restricting the sharing of information that is otherwise legal.

As an attorney who has taken an oath to support the United States Constitution, the 5th Circuit's opinion is beyond chilling.

That's impossible given the politics which precipitated a decision that impacts anyone exchanging information that is not all that dissimilar from the invaluable information exchanged on this forum. That's what makes the court's findings so chilling and requiring comment.

If the US State Department's actions are ultimately allowed to stand, it's not that far a legal road to travel for them to claim information shared on forums like this one are also subject to their review and clearance.

Interesting talk by Markforged 3D Printing about mass production.  They use a printing technique where metal parts go through a standard sintering post processing technique used for metal injection molding which is already in wide scale use.

US government drops prohibition on files for 3D printed arms
State and Defense Departments comply with revised regulations from May 2018.
by David Kopel - Jul. 10, 2018 4:41 pm

Last week the U.S. Department of Defense and U.S. Department of State settled a lawsuit and agreed to end their prior restraint of distribution of computer files for the production of 3D printed firearms. . . .
. . .
in May 2018, the Trump administration proposed revising revise the ITAR regulations. The move for regulatory reform actually began under the Obama administration, but the proposed reforms were never published. Now they have been. Export controls for many ordinary firearms and accessories will be removed from the ITAR list. Exports of such items will instead by controlled by the Department of Commerce. Among the items remaining under the ITAR system are automatic firearms, firearms of greater than .50 caliber, magazines with more than 50 rounds, and sound moderators (a/k/a "silencers"). Non-automatic firearms of.50 caliber or less will no longer be covered under ITAR; among the firearms no longer under ITAR is the semiautomatic AR-15 rifle, the most common rifle in American history. Its typical calibers are .223 and .308--well under the new .50+ caliber rule.

Accordingly, the government defendants revisited the Defense Distributed case. If a particular arm (e.g., the AR-15) is no longer part of ITAR, then it would be illogical for ITAR to be applied to instructions for making the arm. Under today's settlement agreement, plaintiffs and others may freely publish 3D printing instructions for firearms that are not covered under ITAR. Restrictions on distribution of 3D printing information for items that are still under ITAR, such as machine guns or rifles over .50 caliber, remain in place.

Quote
PARIS, 20 July 2018 (ESA PR) — A new ESA-led project is investigating the ways that 3D printing could be used to create and run a habitat on the Moon. Everything from building materials to solar panels, equipment and tools to clothes, even nutrients and food ingredients can potentially be 3D printed. But if you were headed to the Moon, what would you want to 3D print, to turn a lunar base into a place that feels like home? Tell us your idea, to win a chance of actually getting it printed.

Global space agencies are focused on the concept of a lunar base as the next step in human space exploration – and 3D printing represents a key technology for making it happen.

The aim would be to ‘live off the land’ as much as possible, by printing as many structures, items and spares out of lunar regolith as possible, or by using and reusing materials brought for the mission, rather than continuously relying on the long, expensive supply line from Earth.

Maximised 3D printing would also allow on-demand production of items and spares with routine recycling of materials available within the base, making lunar settlement much more self-sufficient and sustainable.

Screen grab from a Stratasys ad.  Any guesses?  The rear model has an Aurora logo but I'm not sure if that refers to Aurora Flight Sciences.

On the flying wing model there appears to be some small Air Force insignias which may indicate this could represent a fairly large aircraft.

A take on 3D printing's impact on future industry which I think overstates the case.  "Customers" of 3D printing are more likely to be other companies and not individuals.  Surface finishing and integration/assembly of parts to create a finished product incorporating electrical/electronic and other components will still require traditional methods.
