On October 10, 2019, UMaine (University of Maine) Habib Dagher and his team won three Guinness World Record Awards from the University of Maine composite center, which is currently recognized as the world's largest 3D printer printing vessel. The awards ceremony was broadcast live on Facebook, where Guinness World Records officials recognized many individuals involved in the project.In addition to winning praise from Guinness World Records officials, the team demonstrated the largest 3D printer component ever. The 25 foot long 5000 pound ship was tested at alfond W2 marine engineering laboratory, an offshore model testing facility equipped with high-performance wind turbines and multi-directional wave basins.The massive new 3D printer uses plastic polymer pellets to layer through layers, using up to 500 pounds an hour. Even the 3D printer at Oak Ridge National Laboratory in Tennessee couldn't do it.The University of Maine team won the Guinness world record for the following reasons:● largest polymer 3D printer● largest 3D printing ship● largest physical 3D printer projectState Councillors attended the ceremony, and many other names and organizations helped with the project. Although many developers have created 3D printing works, the project has been combined through a lot of planning, interaction and collaboration, which is a relatively large project.While the team's goal is to create records, their work shows the effectiveness of 3D printing in applications such as the marine industry. However, there is no doubt that this may extend to many other levels and to many other industrial uses today.Today, 3D printing technology continues to innovate, and the scope of innovation also continues to expand, in a variety of new materials (from plastic to metal, to many different alternative forms) to improve new technology, usually in their own production of new products that they want to improve for their creative use.In the process of 3D printing and additive manufacturing, especially in the past few years, many records have been made in the fields of biological printing feasible human tissue, creation of large-scale artwork, and even the whole outdoor sports and leisure products.
