Abstract
We show that a multimode fiber which can be either a graded index fiber or fiber bundle can be used to deliver shaped light to build useful complex parts in areas difficult or impossible to reach with conventional manufacturing tools. We will show complex objects of micrometer scale that are made by additive manufacturing with either a single photon or a 2 photon process. The large effective core area of the multimode fiber allows two orders of magnitude higher pulsed energy transfer while maintaining a spatial and temporal diffraction limit. This enable both subtractive and additive manufacturing.
