This is not your Prusa Mendel. This is the Godzilla of advanced industrial 3d printers, a hybrid metal laser sintering and high precision milling machine.
It can produce highly precise medical and dental implants and high end custom aerospace industry parts. The structures can have intricate internal structure that can decrease weight, improve cooling or add advanced structural properties.
Lumex Avance can also print complex molds and casts with integrated cooling for high cycle injection molding.
Typically, milling produces debris, or chips, of removed material that vary in size. However, the LUMEX machine utilizes dry cutting, meaning no coolant is used. For this reason, the cutters are very small and the machining metal removal is a fine powder. Thus, the porosity is theoretically equal to the particle size of the powder and gets incorporated into the powder mix. Usually, no removal of milling chips is needed.

I found a video demonstration of small particles levitating in air held and manipulated by ultrasonic field.

My first thought was: this could be used in 3d printing!

Particles could be manipulated and held in shape by this ultrasound technology and then melted together by laser or ultrasound energy itself. I know it is far fetched theory ... but somehow I think it could be done ...

Ultrasonic technology is already used in high-end metal 3d printing by Fabrisonic:

And similar technology is also used to weld plastic:

So, all these technologies could be merged together, why not?

Video of ultrasonic particle levitation:


Video description:

The essence of levitation technology is the countervailing of gravity. It is known that an ultrasound standing wave is capable of suspending small particles at its sound pressure nodes and, so far, this method has been used to levitate lightweight particles, small creatures, and water droplets.
The acoustic axis of the ultrasound beam in these previous studies was parallel to the gravitational force, and the levitated objects were manipulated along the fixed axis (i.e. one-dimensionally) by controlling the phases or frequencies of bolted Langevin-type transducers. In the present study, we considered extended acoustic manipulation whereby millimetre-sized particles were levitated and moved three-dimensionally by localised ultrasonic standing waves, which were generated by ultrasonic phased arrays. Our manipulation system has two original features. One is the direction of the ultrasound beam, which is arbitrary because the force acting toward its centre is also utilised. The other is the manipulation principle by which a localised standing wave is generated at an arbitrary position and moved three-dimensionally by opposed and ultrasonic phased arrays. We experimentally confirmed that various materials could be manipulated by our proposed method.

Printing technologies are expanding further. SenSprout is a device for monitoring air and soil moisture in order to optimize agricultural production and irrigation management. It is produced by printing the electronic circuits on paper with silver nanoparticles. It is powered by ambient radio frequencies (it harvests 2,4 GHz frequencies) and transmits data on same frequency.
I wonder how practical it would be for real life application since it looks fragile, it is currently deployed and tested. Even if not practical, concept is excellent technology demonstrator: downloadable printable sensors powered with surround electromagnetic radiation. Cool!
They use commercially available inkjet printers and commercially available conductive ink from Mitsubishi.

I think this is Mitsubishi silver nanoparticle ink they mentioned: http://www.mitsubishiimaging.com/digital-imaging-diamond-jet-NANOINK.html







Applications of 2d printed electronic circuits are infinite, similar to 3d printing. Hopefully this technology will soon expand into DIY space. There are many corporate and academic developments in conductive inks, but conductive ink can be also produced in DIY / home lab setting (this one doesn't work on paper):

Implant is made from titanium powder, it costs some 10 USD. It is already used in Japan and helps people with various bone damage conditions where it replaces damaged parts.

WOW! This just looks amazing and beautiful. Maybe little creepy also. Still, it is a remarkable peace of work.
