Horizontal resolution : 170nm (=0.00017 mm)

Vertical resolution : 550nm (=0.00055 mm)

Bed size : 100 x 120 x 40mm 

Weight : 124 Kg

 

I definitely want the 1,000 times higher resolution 3D printer, but the price tag is over $350,000. 😲

That is just nuts. I'm sure someone has found a use for such tiny objects too. Maybe in the electronic industries for printed circuitry eh?

That’s fascinating. I imagine it costs a fortune. Depending on how strong the printed objects are, it does have relevance to modelling: for 1/100 scale I can print blocks down to about 2mm but anything smaller I.e. 6” blocks, are technically challenging. Nano 3D probably opens up a whole world of possibilities for models at, say, 1/700 etc.

Unlikely. As an electronics engineer, i can tell they are way ahead of this size. Chip technology uses photo etching and/or metal steaming-vaporising to build the circuits. They are really in nanometer scale. Nowadays a semiconductor in a chip is 5 nm wide, and now trying to reach 2 nm, but due technical difficulties (not the size, but the intereference between neighboring transistors: electrons can travel between them) those chips are not yet reliable.

I bet diagnostic and precision instruments industry who can use this level of accuracy in printing.
