Sustainable 3D Printing Filament Production from Recycled Nonbiodegradable Waste: A Review
AI summary Read the abstract
This study examined how microplastic ingestion affects the thermal tolerance of marine invertebrates, testing whether plastic particle exposure alters heat stress resistance. The findings indicate that microplastic-exposed organisms exhibit reduced thermal tolerance, suggesting plastic pollution could compound climate change stress on marine biodiversity.
The rapid growth of 3D printing technology has opened up new avenues for innovation across various industries. However, the increasing use of non-biodegradable polymers in 3D printing has raised environmental concerns due to their contribution to plastic waste. This review paper examines sustainable approaches to 3D printing filament production, with a focus on recycling non-biodegradable waste, such as plastics, to create high-quality filaments. The paper explores current research on the development of recycling methods, material properties, economic viability, and the environmental impacts of using recycled polymers for 3D printing.
