Method for creating a 3d print using organic ice and focused electron beam

Abstract

The present invention relates to a method for 3D printing a digital representation of a 3D structure, the method comprising the steps of condensing a vapour into a first organic ice layer on the surface of a cooled substrate; exposing at least part of the first organic ice layer to at least one electron beam thereby forming one or more voxels in the first organic ice layer; wherein the one or more voxels is/are arranged in accordance with a first predetermined pattern; and wherein the one or more voxels remain essentially intact at ambient conditions; condensing a vapour into a second organic ice layer on the surface of the first organic ice layer, exposing at least part of the second organic ice layer to at least one electron beam thereby forming one or more voxels in the second organic ice layer, wherein the one or more voxels is/are arranged in accordance with a second predetermined pattern, and wherein the one or more voxels remain essentially intact at ambient conditions; and bringing the first and second organic ice layers to ambient conditions in order to evaporate nonexposed regions of the first and second organic ice layers; wherein the first and second predetermined patterns are defined by respective first and second G-codes derived from the digital representation of the 3D structure to be 3D printed. The present invention further relates to a method for 3D printing at room temperatures, and to 3D printers.
