Sustainable Rapid Prototyping with Fungus-Like Adhesive Materials

Abstract

The purpose of the research work presented in this paper is to develop a sustainable rapid prototyping technology. Fused filament fabrication using synthetic polymers is today the most popular method of rapid prototyping. This has environmental repercussions because the short-lived artifacts produced using rapid prototyping contribute to the problem of plastic waste. Natural biological materials, namely Fungus-Like Adhesive Materials (FLAM) investigated here, offer a sustainable alternative. FLAM are cellulose and chitin composites with renewable sourcing and naturally biodegradable characteristics. The 3D printing process developed for FLAM in the past, targeted large-scale additive manufacturing applications. Here we assess the feasibility of increasing its resolution such that it can be used for rapid prototyping. Challenges and solutions related to material, mechanical and environmental control parameters are presented as well as experimental prototypes aimed at evaluating the proposed process characteristics.

Advancing 3D Printing through Integration of Machine Learning with Algae‐Based Biopolymers

“…Dritsas et al. 101 address the critical issue of shrinkage in 3D printing with water‐based cellulose‐chitin biopolymers, a common challenge in achieving geometric accuracy in biofabrication. The study introduces a novel prediction‐correction scheme, leveraging neural networks to predict shrinkage deformations and adjust machine paths accordingly.…”
