Methods of fabricating a 3d device using ablation

A method of fabricating a three-dimensional device, comprising:

• applying a layer of support material in a liquid form on a substrate surface by one of:
• ink jet printing, laser-induced forward transfer (LIFT), digital light projector (DLP) printing, stereolithographic (SLA) printing, or mechanically;
• hardening the support material by (i) ultraviolet (UV) curing at a first wavelength to create a solid layer of support material, and (ii) UV curing the solid layer of the support material at a second wavelength to create a hardened outer surface of the support material, wherein the second wavelength differs from the first wavelength;
• ablating, using a laser beam, undesirable portions of the solid layer of support material to create an area within the solid layer of support material in which a desired structure will be formed;
• depositing active material into the area within the solid layer of support material in which a desired structure will be formed;
• repeating the applying, hardening, ablating, and depositing steps, layer by layer, until the three-dimensional device has been completed;
• and
• removing remaining support material by water or other solvent.
