Green and affordable inks for more inclusivityMaterials that perform extremely well are already present in our environment: wood, clay, latex, gelatin, etc
Additive manufacturing (AM) technologies are disrupting our society by proposing a faster and customizable way of producing parts
The main reasons in favor of the development of 3D printing (3DP) technologies for large-scale fabrication are (i) the automation of the process that reduces the need of manpower in fabrication plants, (ii) the possibility of fabricating customized parts and a large range of products using one machine, (iii) the diversity and complexity of the shapes as compared to standard processes, and (iv) the reduced amount of waste as compared to substrative fabrication methods
Summary
Materials that perform extremely well are already present in our environment: wood, clay, latex, gelatin, etc. These materials are green, affordable, and available world-wide. To increase inclusivity of 3DP, inks and protocols using these materials should be available, and added value using 3DP demonstrated. Inks based on agricultural waste and fungi open new promises (Figure 3A,B).[11] While the fungus degrades the nutrients from the waste, it grows a tight network to yield a stiff composite that has anti-fire and sound attenuation properties, among others. The DIW of this ink could help optimize the fungus growth and resulting properties, for applications as furniture or in housing
