Direct-ink-write 3D printing of flexible all-solid-state micro-supercapacitor based on MXene-hydroxylated nanocellulose-carbon nanotubes. Article Publication Date. 5-Jun-2025.

Direct ink writing (DIW)—where material is forced (extruded) through a nozzle and selectively deposited layer by layer—works best for printing highly viscous materials like silicone.

Now, Mahadevan has turned his attention to applying what he learned about Pollock's coiling instabilities to direct ink writing, a versatile means of 3D and 4D printing.

The 3D-printing method they used, called direct ink writing (DIW), involves squeezing liquid inks through a microscale nozzle to “draw” the desired structure a little bit at a time.

The study outlines the methodology behind the UV-assisted direct-ink-write 3D printing approach, which involves manipulating light to control the assembly of specially designed crosslinking polymers.

SUTD researchers 3D print biodegradable conductive electronics using direct ink writing and cellulose acetate dissolved in acetone.
