Fabrication of Delta-Frame 3D Printer to Reduce Print Time
Abstract: 3D printing refers to a process of printing 3-dimensional objects, also known as “rapid prototyping”. The reason behind the wide use of a 3D printer is that it enables the creators to deliver a model of what they want in a short period of time, which is tested and quickly remodelled if needed. This significantly decreases the expected time to get from the model stage to the final product. At …
