Celebrating Vacuum Casting: Bridging the Gap Between Prototyping and Full-Scale Production

Vacuum casting is a technology that often flies under the radar when people discuss 3D printing, but its significance cannot be overstated. At its core, vacuum casting is a fast, efficient, and cost-effective method for producing high-quality plastic parts. The process uses silicone molds, which are created from a 3D-printed master, to deliver parts that are comparable to injection-molded components. This makes it particularly suitable for applications such as fit and function testing, and small series of end-use parts. It serves as a powerful complement to 3D printing for industries that need small-batch, high-quality production — whether for functional plastic parts, prototypes, or final products.

But one of the most exciting applications of vacuum casting has been in the medtech industry. When we talk about 3D printing in healthcare, personalized solutions like patient-specific implants or custom surgical guides often steal the spotlight. However, vacuum casting is playing a growing and equally important role in the manufacturing of general-use medical devices used in diagnosing and treating patients. Medical devices often require not only precision but also a high level of customization, depending on their use. Vacuum casting offers a unique advantage here by enabling the fast, cost-effective production of small batches of medical devices all while maintaining the high standards required in the medical field. Although these general-use devices may not always make the headlines, they are crucial for everyday medical procedures, ensuring patients receive the best possible care.

Vacuum casting occupies a unique space in the world of manufacturing. It sits between prototyping and serial manufacturing, filling a crucial niche for industries that need high-quality parts without the overhead costs or lead times associated with large-scale production. It’s this flexibility that makes vacuum casting such an essential process, allowing companies to innovate more freely without the constraints of traditional manufacturing techniques.

For industries like automotive, industrial goods, and healthcare, vacuum casting serves as a valuable complement to both injection molding and 3D printing. It combines the speed and flexibility of 3D printing with the material diversity and surface quality of injection molding, offering the best of both worlds to meet diverse production needs.

As we reflect on these 20 years in the Czech Republic, we celebrate the achievements of our team and the impact our vacuum casting operations have had across industries. This is a technology that may not always be in the spotlight, but it continues to create immense value for our customers and their end-users.
