Free 3D Systems Whitepaper Discusses Scalable, Digital Molding Process and Figure 4 3D Printing https://ift.tt/2QcpHMl Injection molding was invented nearly 150 years ago, and while the manufacturing process has been improved several times over the years, something that hasn’t changed about the technology is its need for tooling, which can take weeks and even months to complete. Digital molding is a scalable 3D printing process that can increase the speed and simplicity of producing plastic parts, allowing designs to move from CAD to manufacturing without the use of tooling, and can make parts too complex for injection molding to handle. This disruptive technology – a good alternative for low-volume plastic part production – is also the focus of the latest whitepaper by 3D Systems. The company’s tool-less digital molding is backed by its configurable, modular Figure 4 manufacturing process, making it possible to facilitate part design iterations on the spot and increase product transitions without retooling.
Figure 4 technology can manufacture parts out of hybrid materials that are biocompatible and durable, and feature elastomeric properties and high temperature deflection. The process uses arrays of manufacturing modules, serviced by robotics, to rapidly output a finished geometry; downstream workflows are also used to optimize throughput, and the Figure 4’s processing speed “enables use of reactive plastic resins with short vat lives, leading to tough, functional parts such as those used in thermoplastic applications.” The Figure 4 SLA configuration was patented by 3D Systems’ co-founder Chuck Hull 30 years ago, when the technological advancements he needed to make the process a reality were not yet available. But progress in advanced robotics systems, continued SLA and materials advancement, digital texturing, CAD/CAM software that enables 3D design, and higher speed in processing raw materials in the vat have led to the technology’s current digital molding process.
Robotic arms that move the parts through each process step allow for streaming parts production, and digital inspection can also be integrated into the Figure 4 modules. There are many benefits to digital molding technology, such as lower costs, more efficient part customization, greater part complexity, no minimum order quantity or batching, no more physical storage issues, and because there’s no waiting for tooling, production can start right away. This means more flexibility, and multiple products can also be created at the same time. Additionally, digital molding configurations complement existing production methods used on the shop floor.
The whitepaper also discusses the implications of digital molding on cost and Product Lifecycle Management, in addition to revealing the results of its benchmarking study that compared the design and production of an automotive vent using traditional injection molding versus digital molding. Perspective from industry expert Tim Shinbara, vice president of the Association for Manufacturing Technology (AMT), was also shared.
