MultiJet 3D Printing (MJP) – High-Resolution Multi-Material Additive Manufacturing

MultiJet 3D Printing (MJP) is an advanced additive manufacturing process that uses inkjet printheads to deposit microscopic droplets of photocurable resin or wax onto a build platform. Each layer is immediately cured using UV light, producing highly detailed, smooth, and dimensionally accurate parts.

How MultiJet Printing Works

MJP builds parts layer by layer using precise droplet deposition and UV curing. This process allows for exceptional detail resolution and fine surface finishes compared to many other 3D printing technologies.

• Inkjet-based deposition of photopolymer resin or wax
• UV light curing after each printed layer
• Layer-by-layer additive manufacturing process
• Water- or melt-dissolvable support materials

Key Features of MJP Technology

• High resolution: Produces fine details and smooth surface finishes
• Multi-material capability: Combines rigid, flexible, transparent, and colored materials in one print
• Complex geometries: Enables intricate designs and internal structures
• Easy post-processing: Dissolvable supports reduce manual cleanup

Applications of MultiJet 3D Printing

MJP is widely used in industries requiring precision, detail, and visual accuracy:

1. Dental: Models, surgical guides, and orthodontic devices
2. Jewelry: Detailed patterns, molds, and casting masters
3. Product prototyping: High-detail concept and functional prototypes
4. Medical and design: Anatomical models and visual prototypes

Material Performance and Limitations

While MJP delivers exceptional surface quality and detail, its material strength is generally lower compared to technologies such as SLS (Selective Laser Sintering) and FDM (Fused Deposition Modeling). It is best suited for visual models, precision prototypes, and applications where fine detail is more important than mechanical strength.

MJP remains a versatile solution for producing highly detailed, multi-material prototypes with excellent surface finish and design flexibility.
