THREE-DIMENSIONAL PRINTING PLASTIC ONTO METAL

摘要

A three-dimensional printing system includes a reservoir containing a UV curable resin therein, a UV light, an oxygen delivery system, and a movable platform having a build surface configured to support a three-dimensional printed part at a non-planar feature thereon. The bottom of the reservoir can be UV-transparent and oxygen permeable, so the resin is cured by UV light at the build surface or printing part, but not cured despite UV light at the oxygen rich region near the reservoir bottom. Non-planar features include recesses and/or protrusions at the build surface, which can help form backsides of printed parts. Metal parts can be fitted to non-planar features to have thin insulative three-dimensional layers printed thereto. Many identical non-planar features can be used to mass-produce identical printed parts, which can be for electronic devices.

1. A three-dimensional printing system, comprising:
a reservoir configured to contain a curable liquid therein; a curing component configured to cure the curable liquid contained within the reservoir during a three-dimensional printing process; a gas delivery system configured to provide a gas into a portion of the curable liquid during the three-dimensional printing process; and a platform having a build surface configured to support a three-dimensional object being printed from the curable liquid during the three-dimensional printing process, wherein the build surface includes one or more non-planar features thereon.
