3D printing enables the mass production of custom designs - this is an interesting development that moves us closer to the point that anything that we can imagine creeating manually can indeed be produced at a reasonable cost.

"Chinthavali's first prototype uses 55 percent printed parts to achieve 99 percent efficiency"

Therefore 1% of those 30KW - estimated at only 300W is converted to heat. Very promising for electric cars and many other systems.

@wilber_xbox you are right that power management chips do not require sophisticated /advanced node technology that can not be 3D printed. X-Y feature sizes are not as challenging here but the vertical metal stack certainly is (for eg. n-well to p contact). With the form factors for inverters one expects these days, I am not certain if 3D printing can ever deliver when it comes to making a power MOSFET.

@Sanjib.A: for palm-sized form factor, it is possible to thermally manage 30Watts of dissipation with the right heat sink. Assuming these inverters will not be 'handled' by any one while in operation, once can take some liberties with the max allowable surface / case temperature of the inverter (depending on metal or plastic case). But if the inveter is going to be touched regularly by some one while in operation, OSHA has specific limits for max surface temperature for plastics & metals. There is also a temperature spec for scalding from such components.

I agree that 3D printer will not be able to go beyond a certain miniaturization level but a lot of IC chips are really of um technology which might be possible to print. I guess it will help a lot to bring customized chips into limelight again.

Withe the kind of miniaturization that has happened in the electronic parts today, I don't think the 3D printers will ever be able to generate that kind of electronic circuits . What can be achieved using 3D printers is only the packaging  and the big components such as heat sinks, terminal blocks and such things

I would say below average work.

ORNL, Oak Ridge National Laboratory (not Laboratories) is actually in Oak Ridge, TN. Check it out http://www.ornl.gov/ornl/contact-us

If semiconductor material can be used so readily then maybe someone will figure out a way to print the IC chip for solar, flexible circuits etc.

30 Kilowatt??

"...packing a 30-kilowatt inverter into the palm of your hand."

This is really amazing!! Even if we consider 0.1% loss, it is ~30watts of dissipation in the size of a palm. Is that manageable without special thermal management techniques?
