Additive manufacturing with UV curable polydimethylsiloxane (PDMS) was achieved using UV laser direct writing. In these experiments, UV curable PDMS was locally polymerized to fabricate 1D and 2D single layer structures, as well as 3D multilayer structures. Line arrays with line widths between 18 and 47 lm were produced, and it was observed that good stability and repeatability of the photo-polymerization in the UV curable PDMS was possible. The 3D structures demonstrated the absorption depth of the UV curable PDMS, which was deeper than 3 mm, and enabled the fabrication of 3.1 mm tall structures with an aspect ratio of 2 in only a single layer. The 3D structures were sufficiently strong to show elastic properties. All surfaces were smooth and transparent. In addition, UV laser direct writing of UV curable PDMS realized patterning with uniform resolutions at each layer.
