Using 3D printing, Maruho Hatsujyo Innovations, a Japanese company focusing on pharmaceutical and medical packaging machinery, has developed a new prototyping service for blister cavity design. “Additive manufacturing is all the rage in manufacturing, with companies making everything from aircraft blades to components for small machines. Why not apply it to blister packaging too?” says Benjamin Voelcker, Product Manager at the Medical Packaging Machinery Division of Maruho Hatsujyo Innovations.
Clearly, it’s better (and much less expensive) to find – and fix – a problem at the design stage rather than discovering an issue further down the line. And that’s why extensive prototyping is attractive – but it’s also time consuming. “Prototyping is particularly important for blister packaging applications because the production tooling for blister machines is expensive. Lead times for traditional prototypes can run to 1 to 2 months because of the metal tooling involved,” explains Voelcker. “When testing cavity designs, brand owners want to be able to make changes quickly that take into account the properties of the film material and the behavior of the design.” For blister cavities, drug manufacturers need to assess factors such as childproofing, and conduct tests for stability and material limits for filming/lidding.
