Virginia Tech Researchers 3D Print Kapton Using Direct Ink Writing
- Nov 20, 2018 -

Last year, a team of researchers at Virginia tech developed a method for 3D printing Kapton.Kapton is a foill - like polyimide with excellent thermochemical stability and is often used in aerospace insulation. It also ACTS as an insulator and is resistant to ultraviolet radiation.It does not dissolve in the solvent, reduce the temperature of about 550 ° C.

The 3D printed material is written in direct ink, and the printed part has similar properties to the commercial carpton film.They have similar mechanical properties of up to 400 ° C, and their degradation temperature of 534 ° C. According to Rau, SLA is better for the overall object of 3D printing, while direct ink writing is better for different materials of 3D printing.

In research on SLA 3D printing last year, Jana Herzberger, a postdoctoral student in the Long team, created Kapton's precursor polymer in liquid form.The liquid is not suitable for writing directly in ink because it cannot retain its shape after being squeezed.Instead, hertzberg invented a resin similar to peanut butter.
