Developments in 3D printing of carbon fiber reinforced polymer containing recycled plastic waste: A review

3D printing process has gained significant attention because of its ability to manufacture complicated geometries. The process also has a lot of potential for reducing plastic waste. In recent years, the use of carbon fiber has become increasingly popular as a reinforcement material for 3D-printed objects. The combination of plastic waste and carbon fiber has the potential to create high-strength and lightweight structures for various applications. This presented paper reviews the advancements in 3D printing using plastic waste, focusing specifically on fused deposition modeling (FDM) and selective laser sintering (SLS) printing methods for carbon fiber composites. The study highlights the important role of materials in the 3D printing process, especially regarding the difficulties in producing non-recyclable plastics. The study highlights composite materials and processes and the industries that utilize these technologies. One of the key aspects of the article is the exploration of the impact of 3D printing on the environment through the recycling of plastic waste. This study shall be helpful for the demonstration of turning 3D printing plastic waste into durable, functional objects while minimizing its environmental impact.
