Pioneered by Stratasys in 2007, polyjet 3D printing -- while less widely used than SLS or SLA -- is an effective tool for printed parts that require a high level of surface detail (0.1mm details are achievable) and a smooth, high-quality finish. Its applications include: Highly detailed display models that require multiple colours, such as medical models. Prototyping stages where a large number of iterations of a part are expected. Polyjet’s printing speed makes it ideal for this. Limited-run non-functional parts, such as decorations for luxury cars. Generating moulds and ...

One of the most effective applications of 3D printing in the industrial world has been injection moulding, where the use of printed moulds has helped reduce materials cost, streamline workflows, and maintain consistent quality. However, it’s not the only manufacturing technology where 3D printing offers opportunities for new improvements and enhancements. As part of an ongoing drive to streamline and improve their production processes, forward-thinking foundries are combining 3D printing with sand casting.   What is sand casting? Sand casting is the process of casting molten metal using sand-based moulds. To begin with, ...
