Zack Polizzi and Maxwell Tucker of the North Carolina School of Science and Mathematics propose MATIER-ALL, a multi-material 3D printer. Current 3D printers have limited material selection, slow print speeds, and struggle with complex structures. MATIER-ALL will use selective laser sintering to print quickly in multiple materials directly from CAD drawings. They have an initial prototype and plan to develop the business through partnerships, crowdfunding, and an online store. Their market analysis shows a $7.5 billion total addressable market for improved 3D printers.
