3D printed buildings made by California’s Contour Crafting have gained a firmer foundation with new investment from concrete formwork specialists, the Doka Group’s investment arm.
“Very soon, we’ll have the first series-ready deployable robotic 3D construction printer,” says Behrokh Khoshnevis, President and CEO of Contour Crafting Corporation.

GE has mass produced via 3D-printing a metal nozzle tip that would have been
difficult to produce using other methods:

An Epiphany Of Disruption: GE Additive Chief Explains How 3D Printing Will
Upend Manufacturing.
Jun 21, 2017 by Tomas Kellner

The nozzle met the team’s wildest expectations. Morris’ machine not
only combined all 20 parts into a single unit, but it also weighed 25
percent less than an ordinary nozzle and was more than five times as
durable. “The technology was incredible,” Ehteshami says. “In the design of
jet engines, complexity used to be expensive. But additive allows you to get
sophisticated and reduces costs at the same time. This is an engineer’s
dream. I never imagined that this would be possible.”

But what I really find interesting in this article are some comments GE's
additive manufacturing head Ehteshami said about what he see's for the
future of 3D-printing:

“I was excited but also disturbed,” says Mohammad Ehteshami after a
vendor printed an complex part for a jet engine. “I knew that we found a
solution, but I also saw that this technology could eliminate what we’ve
done for years and years and put a lot of pressure on our financial model.”

and:

Ehteshami calls his additive awakening an “epiphany of disruption.”
Says Ehteshami: “Once you start thinking about it, you realize both
intellectually and emotionally ‘Oh my God, if I don’t start moving, somebody
else will.’ You are excited because you are an engineer, but you are also
afraid because you are a human being. Both of these feelings start pulling
at you to say: ‘I’ve got to go, I’ve got to go.’ And you start running.”

From the way I interpret what Ehteshami is saying, it mirrors something I've
been thinking. You can imagine not just cars being fully 3D-printed, but
entire airplanes, tractors, construction vehicles, refrigerators, air
conditioners, and everything else called "durable goods". But this would
mean nearly all manufacturing jobs would be replaced by 3D-printing
machines. That is a major economic disruption.

Not only that, but all these would become much cheaper. Would the companies
that produce them even be billion dollar companies anymore?

Not Printing but same mechanics... a desktop Pick-n-Place/Rework station

Putting this guy together, just waiting for some high precision parts to be made and I'll put it together.
Looking at a theoretical accuracy of 50 nanometers, but I'll be happy with 1 micrometer. All depends on sourcing some decent ($$$) screws and nuts.

What does it do?

What it will do.. eventually

It's geared for small scale/home assembly production.
a) Pick-n-Place electronic components.

b) InfraRed Rework machine - Removes faulty components (like BGAs) and places a new component in it's place - automatically.

c) etc.. whatever your imagination has. As you can see in the picture it has a vertical base plate, which will accommodate any head type you'd like (eg 3D printing head, IR head, Pick-n-Place head, CNC head, laser head..etc.. all with their associated accessories).

The bottom base plate has a thermal plate and pad (150-180 Degrees C) insulated by a ceramic plate underneath.

At the moment the heatsinks and thermal transfer/insulation looks good.. naturally construction and testing is the only way find out

Electronics are high resolution motor modules that are being slapped together with simple interface cards, and home grown controller.

Fun to be had

Continuing the watery theme...

https://3dprintingindustry.com/news/3d-scanning-objects-dipping-water-118886/

New research has identified a novel way of 3D scanning objects by submerging them in water.
The researchers based their method on Archimedes’ ancient principle of displacement. By measuring changes in water volume, the team can reconstruct the shape of 3D objects.

Must be some clever algorithms in there.

Aw! I was looking forward to seeing a 'scan' of the developer's head. :lol:

Well, its not a too magic idea. Essentially the object is scanned by changing its orientation between various dives - pretty much scan lines in various angles. The trick is reconstructing the shape from the displaced volume in different orientations - but that is actually ship hull design reversed. :lol:

Florida-based space company Rocket Crafters Inc (RCI) has been granted a $542,600 research contract by DARPA to develop its 3D printed rocket fuel engine.
With the eight month-long agreement, Rocket Crafters will be enlisted to design, build, and test the hybrid rocket engine.

Nah.. it won't work.. It will shatter at full thrust
What are they thinking :facepalm:

The 3D printed “Project X” Aerospike engine made through a collaboration between Monash University, Amaero (an offshoot of Monash), Next Aero and Woodside energy has been successfully fire-tested in Australia.
Design and production of the engine was completed in just four months, following previous prototypes unveiled in 2015.

The Damen Shipyards Group, headquartered in Gorinchem, Netherlands, has given an update on the progress of its 3D printed tugboat propeller. Nicknamed “WAAMpeller” the project has is been in development since April 2017, and is the product of a venture between the Damen shipbuilders, RAMLAB, Promarin, Autodesk and Bureau Veritas.

Toward the development of its next generation space exploration vehicles, NASA has significantly ramped up efforts to incorporate 3D printing in component design.
In July, the administration’s engineers performed 30 firing tests of a bi-metallic 3D printed rocket igniter at the Marshall Space Flight Center in Huntsville, Alabama. After analysis at the University of Alabama, researchers found that the two alloys, based in copper and Inconel, fused to form a strong bond.

Four months after launch on the Ariane 5 spacecraft June 1 2017, the Airbus-made EUTELSAT 172B satellite has reached geostationary orbit 35,786 kilometres above the Earth’s equator. Reaching the determined position was achieved by electrical as opposed to chemical propulsion, making it the fastest electric orbit raising (EOR) to date.

Based in Los Angeles, Relativity Space is developing a new 3D printer for, “scaling and sustaining an interplanetary society”.
Since founding in 2015, Relativity Space has received $10 million in funding – with backers including Mark Cuban and Y Combinator.
The company promises that 3D printing will allow them to go, “from raw material to flight in less than 60 days” and claims their Stargate 3D printer is, “the largest metal 3D printer in the world.”
