Very powerful new technology.  Not to be too semantical, this sounds more like a subtractive process, where printing is an additive process.  I would think it would be 3D CNC Vs. where you have it at 3D printing at the time of my writing this.

Yes, you are right. It is a subtractive process, and as I mentioned in the story, the name of the commercial version--NanoFrazor--is a play on words between the English word razor and the German word for "milling machine," frase. That said, it does sculpt 3D images of structures that can be filled in with deposition and fits in well with the other subtracive processes used in chip fabrication.

Fabrication of phase shift mask? That could be one application.

Few days back I did wrote about chip prototyping 3D printer for home. So Big Blue makes my dream come true! I asked for 20nm but this is also good to start.

this is pretty cool. I think that precision and the scale make this tool more fascinating.

IBM in the millipede nanostorage design along with other "Frazor" nanomilling inventions essentially covered this area about 20 years ago.  Indeed the tip image looks very much like the millipede thermal tip.

Although not addressed in this article or perhaps part of the NanoFrazor effort additive methods were a very early goal of these designs.  Such additive systems are true 3D Printers in that they work by adding material to target surface.

Finally some methods supported and used both additive and subtractive methods. 20 years ago these systems had 2.5 angstrom resolution in all axis (imaging resolution), surface modification resolution of 2nm in X,Y and Z.  They are much improved today. The machines are built and sold by a California company.  The creation of these methods was done in Northern California.  The earliest machines used an IBM AFM platform as a base element.

Printing of conductive and non conductive parts

It would be possible to print the things in which there is no isolation needed.

But in printing a chipboard how will they differentiate between semi conductors and plastics and isolation of those semi conductors to avoid short circuits.

LATEST ARCHIVED BROADCAST

What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
