MJP (MultiJet Printing) is an advanced additive manufacturing process used primarily for creating highly detailed wax patterns. These wax patterns are commonly used in investment casting, particularly in jewellery, dental, and industrial applications where precision and surface finish are paramount.

MultiJet Printing technology operates in a similar way to traditional inkjet printing, but instead of ink, it uses droplets of wax material. The printer head deposits layers of molten wax onto a build platform, which quickly solidify to form the desired 3D shape. Each layer is built up sequentially until the full model is complete. A support material, which is also a type of wax, is printed simultaneously to enable the creation of complex geometries and overhangs. This support wax can be easily melted away or dissolved after the printing process, leaving the final wax model.

The primary material used in MultiJet Printing is a specialised wax formulation designed for compatibility with investment casting processes. The support material is typically a softer wax with a lower melting point, allowing for effortless removal without damaging the delicate model.

• Jewellery: Enables the production of intricate and highly detailed wax patterns for lost-wax casting, reducing manual labour and improving repeatability.

• Dental: Used to create precise dental crowns, bridges, and prosthetics with excellent fit and finish.

• Industrial: Produces complex components for aerospace, automotive, and other sectors requiring metal parts with intricate internal features.

• High Accuracy: Delivers exceptional detail and surface smoothness, often surpassing traditional hand-carved wax models.

• Design Flexibility: Allows the creation of complex geometries that would be difficult or impossible to achieve by hand.

• Efficiency: Multiple wax patterns can be printed in a single batch, accelerating the production workflow.

• Clean Removal: Support wax is easily eliminated, ensuring the final pattern is ready for casting with minimal post-processing.

MultiJet Printing marks a major advancement in creating highly detailed wax patterns for precision casting. By leveraging the precision and repeatability of digital manufacturing, it streamlines the workflow for jewellery, dental, and industrial applications, ensuring high-quality results and enabling innovative designs.
