Robotic Incremental sheet forming 

Many of new concepts are based on old. Robotics and CNC just allow for less labor, flexibility, consistency and repeatability.

the first sailors used to weld their ships with lightning strikes, many things never change

No :)

No just using a ball pin for deforming and different strategies for programming. Never scanned the springback. But possible to scan it and give a feedback to deformation strategy to get the planned result.

Hy Mauricio, in comparison with hydroforming you are completely flexible in terms of shape and dont have to premanufacture anything before. This deformation of the sheet can take between 20-50min . Depends on Speed and Accuracy. The precision depends on the ball tip you are using for the deformation. Im using 2 diameters for now 10mm and 20mm. There is a springback in the material, whichI think can be avoided by a second round of deforming or using sensor for calculating the springback for each metal and thickness and reinvorcing the process to deform deeper so that the final result fits the shape you want. In terms of roughness and marks, there are no marks on the shape . its just the oil which shows up in lines whre the tip was moving. If the Tip is gliding smoothly on the shape with oil underneathand you will have no marks if the depth movements are little enough (

I mean, it's held on all sides.

This shape takes approx. 30 min . not really compareably to traditional press molding.

I was testing upto 1.5 mm as I remember

Maybe 2 mm

Kuka this bits are used in some ride in theme parks.

its a manufacturing technique without the use of any mold

Compared to mass production yes according to one piece yes, but not in terms of single piece production or small series.
