We are a leading provider of high-speed, large-format 3D printers and on-demand custom parts services to industrial and commercial customers. Our 3D printers employ a powder binding, additive manufacturing technology to produce parts using various material sets, which consist of particulate materials and proprietary chemical binding agents. We offer our customers the highest volumetric output rate in the industry due to the combination of our large build boxes and printhead speeds. We provide our 3D printers and on-demand custom parts services to industrial and commercial customers serving the automotive, aerospace, film and entertainment, art and architecture, engineering and consumer product end markets. We offer six different 3D printer platforms with build boxes that range from 300 x 200 x 150 millimeters to 4,000 x 2,000 x 1,000 millimeters, with various printhead speeds, which produce volumetric output rates ranging from 0.7 liters per hour to 123.0 liters per hour. All of our platforms support our principal material sets, which include sand and plastics, along with their respective proprietary chemical binding agents.
