Most of the 3D printing resins are synthetic chemicals. Is there any biopolymers to replace resins. If so kindly share some lietrature and suggestion for using biopolymers for 3D printing
Dear Sudhakar M.P , your definition of biopolymer is not clear. Biopolymers can be divided into bio-based polymers and biodegradable polymers. Bio-based polymers are produced from biosources and can be biodegradable or not, for example, starch or bio-based PE. Similarly, biodegradable polymers can be either bio-based or fossil-based, for example, PBAT is fossil-based while PLA is bio-based.
Now, come back to your questions, I think PLA has been used extensively in 3D printing and PLA is both bio-based and biodegradable. If what you are interested in are about natural polymers like cellulose, collagen...., one example is:

Yes Thank you Dear Thai, I would like to know both bio-based and biodegradable polymers for 3D printing. I am interested in algae based polymers for 3D printing and this can be used for biomedical applications.
Thank you for your suggestions and information and pls if you come across any article pls share with me. It will be useful for my research.
