Design and Development of Ultra Violet Curing Based 3-D Printer

UV light technology-based 3D printer is commonly known as Stereolithography (SLA) 3D printer. Photopolymers in liquid form is cured under the beam of UV light to form layer by layer 3D model. A beam of light is pointed that cures a limited area and takes a long time to 3D print a part. An effort has been made in this work to design and fabricate a mask and UV light-based 3D printer for printing 3D models from a liquid photopolymer resin. Samples were also printed to evaluate the performance of this printer. Performance tests were very positive to make this model a commercial machine for printing models for medical applications.
