Extremely small racing car precisely modeled with 3D printer

A team of professors Jürgen Stampfl of the Vienna University of Technology, etc., modeled a very small size racing car with a size of 330 micrometers × 130 micrometers × 100 micrometers with a 3D printer. By the way, micrometer (㎛) is one less than mm (mm), 0.001 mm is 1 ㎛. It took 4 minutes for this modeling, and it seems that the world new record, modeling error was less than 1.

I do not know exactly what I am doing at first.


Sometimes shiverfully ... ...


The picture will change. This is a method called Additive Manufacturing, which is a technique of laying down materials one by one and shaping them.


It gradually became a racing carish style.


Three minutes elapsed ......


And such a racing car was completed.


Although you can see subtle steps when you look up, you can see that it is truly a delicate step compared to the scale at the bottom of the photo. As expected it is 1 ㎛ error.

This is from Klaus Cicha, LondonTower Bridge.


It is quite a large building, but it is reproduced with extremely small size.


Two-photon lithography (2-photon lithography) has been used for shaping in 3D printers, and dramatically improved the details. Processing time has been a bottleneck in the Two-Photon Polymerization (2-photon polymerization) technique, and it seems that it was usually only able to process hundreds of millimeters to millimeters per second, but Professor Stampfl et al. It has greatly improved, enabling processing of 5 m per second.

It is a technology that is not very relevant to the general public, but as the whole 3D printing technology evolves, it should benefit someday. When is data modeling becoming commonplace?
