VersaBuild: A Novel, Multi-scale, Versatile 3d Printer Concept

Abstract

Our team has identified and attempted to solve a major challenge limiting the increased deployment of additive manufacturing in full-scale production environments. As engineers desire for greater flexibility of design grows, and as the diversity of properties achievable and materials usable in additive manufacturing increases, additive manufacturing becomes increasingly valuable and useful. However, the machines used to produce AM parts have largely stagnated in terms of configurability, technology, and design. We have conceptualized a system which enables a single machine to provide the functionality of multiple machines, with minimal operator changes. The gap that was identified by the team was the lack of a system that could accept user-configurable changes to the print resolution and printbed size. This would enable manufacturers flexibility in the size, quality, and quantity of parts produced in a facility of a given size. Significant floorspace savings could be achieved in a facility deploying our proposed solution due to the flexibility of the machine, lowering operational cost. Our envisioned design is similar in concept to a standard Delta robot, which is a three-armed robot that is used in many industrial applications. However, we intend for our design to have extensible delta arms that include position sensing, allowing for a greater range of motion and thus print volume while maintaining precise control over the printhead position. Some of the key risks associated with are system are caused by the novelty of the concept. Our system must undergo significant R&D and requires a fully integrated software, electrical, and mechanical system to be developed.
