Researchers Create 3D-Printed Glass with Complex Geometry

Facebook X LinkedIn Email
ZÜRICH, Jan. 3, 2020 — Researchers from ETH Zürich have developed a technique to produce complex glass objects with 3D printing. The method is based on stereolithography, one of the first 3D-printing techniques developed during the 1980s. The researchers developed a special resin containing a plastic and organic molecules to which glass precursors are bonded. The resin can be processed using commercially available digital light processing technology, which irradiates the resin with UV light patterns. Wherever the light strikes the resin, it hardens because the light-sensitive components of the polymer...Read full article

    glass
    A noncrystalline, inorganic mixture of various metallic oxides fused by heating with glassifiers such as silica, or boric or phosphoric oxides. Common window or bottle glass is a mixture of soda, lime and sand, melted and cast, rolled or blown to shape. Most glasses are transparent in the visible spectrum and up to about 2.5 µm in the infrared, but some are opaque such as natural obsidian; these are, nevertheless, useful as mirror blanks. Traces of some elements such as cobalt, copper and...
    3d printing
    3D printing, also known as additive manufacturing (AM), is a manufacturing process that builds three-dimensional objects layer by layer from a digital model. This technology allows the creation of complex and customized structures that would be challenging or impossible with traditional manufacturing methods. The process typically involves the following key steps: Digital design: A three-dimensional digital model of the object is created using computer-aided design (CAD) software. This...
