Characteristics Of A New Enhanced Recycled Polylactide For Sustainable 3D Printing Through Process Optimization

3D printing has been known as additive manufacturing which fabricate a three dimensional of the desired object, part, or assembly model very quickly in layers by using a 3D computer-aided design (CAD). The fast growth of inexpensive 3D printing machines has provided opportunities to users for making...
