Application

• This project enables sustainable 3D printing of wood structures, offering applications in architecture, furniture design, and construction with minimal waste. It can also be used for creating customized, intricate wood-based components for various industries, including eco-friendly construction and product manufacturing.

Description

Researchers at Rice University have developed a water-based ink made from lignin and cellulose, the primary components of wood, to 3D print wood structures. This innovative approach eliminates wood waste, offering a more sustainable and efficient method for creating intricate wood designs. The 3D printed wood closely mimics natural wood in texture, strength, and appearance. This breakthrough could revolutionize wood construction and promote eco-friendly manufacturing techniques.

Pathway Description:

In this project, an ink made from lignin and cellulose is developed for 3D printing wood structures. The ink is used in a direct ink writing process, layer by layer, to create intricate designs. After printing, the structures undergo heat treatment to enhance strength and durability. The final product is tested for mechanical properties and compared to natural wood.
