3D-printed high-temperature ceramics

Abstract

The invention of a new resistant to high temperature, printed in 3-D and baked under a method of UV light passing through the complex printed form resin, this ceramic would have applications in missile and rocket ships in which a material is necessary to withstand high temperatures and retains its properties.

Keywords: Ceramic, Photosensitive, geometry, Ultraviolet.

The introduction of new technologies in 3-D printing resins and an evolved now exhibiting any new ceramic high density polymeric resins that can be printed and baked under low UV lights, the resin enters reaction to be photosensitive, it raises the temperature and makes the piece is baked, the pieces have properties to withstand high temperatures which have applications in hypersonic vehicles and jet engines.

the first method stereolithography, Where we solidify, polymerize a curable ultraviolet special (UV) preceramic resin and a UV photo initiator with a laser, and so when the ceramic suffer a contraction or expand and the removal of finished much porosity or lack homogeneity, an developed a oxycarbide silicon ceramic having properties of anticorrosion and abrasion resistance; Such cellular ceramic materials are of interest to the core of light panels and ceramic filler sandwich for high temperature applications, which now comment it is that they have produced a nickel microlattice ultralight that for a time was the lightest material in the world; but it is now the world's lightest metal material.

Both processes UV hardening can ultimately produce many different ceramic materials, but for a start team has shown a form in a porous intricate structure, lightweight that can withstand ultra-high temperatures of over 1700 ° C (3092 ° F) and exhibits ceramic silicon oxycarbide force ten times greater than similar cellular ceramic materials, Eckel said. As advances in their investigations.
