Stratasys 3D prints moulds
Some of the latest examples of plastic parts injection moulded on 3D printed mould tools were on display on the Stratasys stand. One of the most recent
converts to the technology is Netherlands-based moulder Promolding, which shared its experiences with the technol- ogy at the show. “Promolding is an injection moulding company and we mainly work with steel moulds,” said Product Development Manger Jeroen Gross. “But because of the type of products we
develop we have quite a large development department.” The company installed an
Stratasys Objet printer four years ago. It recently started to use the machine for mould production to satisfy demand for small production runs and product validation testing. “If you want to try some parts – 20, 50, 100 – then this is the way to go,” he said. Gross said there is a
learning curve to take on and some care has to be taken when using the 3D printed moulds. “You have to be a lot
more careful with high and thin cores,” he said. Not all materials can be
handled. Promolding’s experience is that thermal limitations mean that PC/ABS is just about manageable; PC is too demanding. Tool life time varies according to the material used, mould complexity and the level of precision required in the final parts. Gross said the types of

projects undertaken at Promolding typically result in around 50 parts from one 3D printed cavity. However, Stratasys Solutions Sales Manager Nadav Sella told Injection World more than 800 parts had been produced in POM from a single cavity in one recent project. ❙
