As part of the US Department of Energy, Oak Ridge National Laboratory (ORNL) has done a lot of groundbreaking work in the field of 3D printing, such as 3D printing full-size submarine shells. On April 16, 2018, Antarctic Bear learned from foreign media that its latest development is the production of the first commercial medium / large thermoset 3D printer in cooperation with MagnumVenusProducts (MVP). The machine is installed in the ORNL manufacturing demonstration facility in Tennessee and will be widely used for different critical applications.
This new technology provides a cost-effective solution that uses 3D printing as the technology for printing structures and molds. Working with ORNL enables MVP to develop the software and hardware required to create a 3D printer that can print large thermoset plastics for molding. Thermosetting plastics use special chemical compositions, irreversibly cure from prepolymers or resins, and provide much higher performance than conventional thermoplastics in terms of thermal resistance and impact resistance, and low deformability.
According to Bob Vanderhoff of President and CEO MagnumVenusProducts, "The procurement department will ... shorten delivery time on important molds-thus enabling rapid deployment. This is achieved through ORNL slicing software, which allows Integrate multiple printing process parameters. "
The unique features of this new thermosetting 3D printing system include the most advanced gantry system, which is specifically used to produce molds and other thermosetting structures. In addition, unlike other 3D printers, this new MVP 3D printing system has an efficient roll-in / roll-out bed configuration that reduces the need for labor. For large projects that require a lot of post-processing or preparation work, this will significantly increase productivity because it allows the printer to run continuously while performing pre-processing and post-processing operations on an additional print bed outside the machine.
Its total volume is 16 inches (40.6 cm) × 8 inches (20.3 cm) × 42 inches (1.06 cm), and it can print 50 inches (127 cm) per second depending on the material used. The total deposition rate is about 10 pounds (4.5 kg) / hour, and it is usually possible to print at a resolution of up to 6 mm (0.24 inches), which may be greater depending on the settings used. The build platform can hold 1,000 pounds (450 kg), and the repeatability of the 3D printer is about 0.005 inches (0.127 mm). Depending on the 3D print job, its large size can be easily scaled to multiple sizes.
According to MoeKhaleel, deputy director of ORNL Energy and Environmental Science Laboratory, "This cooperation is very important to accelerate the pace of successful commercialization of new technologies, thereby providing a wider range of applications and performance standards for components manufactured by additive manufacturing."
Founded more than 60 years ago, MVP is an industry leader in the development of systems for processing composite materials. In addition to this thermosetting 3D printing system and other technologies designed for composite materials, MVP also has equipment to support the foam and polyurethane industries (including polyurea, adhesives and epoxy resins). It has customers in industries such as automotive, aerospace and transportation.
The new thermoset 3D printer will be located at the ORNL manufacturing demonstration facility at the US Department of Energy's Office of Advanced Manufacturing for Energy Efficiency and Renewable Energy.
