3D printed transparent glass, light curing (SLA) technology variant（B）

• The entire manufacturing process is actually not complicated (below):
• print out the glass prototype by light curing (SLA) technology
• The prototype is placed at a high temperature of 1300 ° C for sintering degreasing treatment to remove the binder (non-glass component) to obtain the final product – transparent silica glass.

This 3D printed glass has many advantages, such as no holes, smooth surface, high transparency, low coefficient of thermal expansion, heat resistance, and shock resistance. And they are comparable to glass made by traditional methods.

The figure below shows the characteristics of sintered glass and this high resolution nanocomposite. Where a) is the X-ray photoelectron spectroscopy, b) is the Raman spectrum (compared to conventional glass), c) the left is the UV-visible transmission rate (compared to conventional glass), and c) the right is the nanocomposite for casting This new type of SLA nanocomposite
