MakerBot’s Digital Reconstruction Patent

We’ve uncovered a very curious patent application from MakerBot that seems to indicate they’re developing an automated way to reconstruct broken objects. 

The patent application, part of a series of patent applications for various usage scenarios, makes this claim:

A method comprising: providing a broken part having a number of pieces including a first piece and a second piece broken from an integral part; scanning the first piece and the second piece to obtain a first digital model and a second digital model; providing information about the integral part; processing the information, the first digital model, and the second digital model to obtain a third digital model of the integral part prior to becoming broken; and fabricating a duplicate of the integral part from the third model.

What does this mean, exactly? In spite of the near-unintelligible legal wording we believe it could mean this:

You 3D scan the broken pieces of an item; software reconstructs the original object, which can then be 3D printed – replacing the original broken item.

This could be a game-changing new usage scenario for 3D printing, if MakerBot can pull it off. It will require some tricky 3D software to logically assemble broken bits into a new model that closely resembles the original object. 


There will be limits to what’s possible. Imagine an item cracked into so many small pieces that the fragments would become ambiguous: You could not reconstruct the object. This is why we think this process is intended for scenarios involving a small number of broken pieces scenarios only. 

We’re very interested to see if MakerBot follows through on this, because watching the reconstruction process unfold will seem like magic.
