Material Jetting (MJP) is a high-resolution 3D printing for jewelry technology known for exceptional detail, smooth surfaces, and precise accuracy. Often compared to inkjet printing, MJP jets tiny droplets of photopolymer material layer by layer, instantly curing them with UV light. This process captures even the most delicate textures, making it the go-to choice for high-precision 3D printing applications.
Unlike SLA or FDM, MJP 3D printing eliminates support structure concerns by encapsulating models in wax during printing — the wax naturally supports overhangs and is melted away after production.
Best Applications for Material Jetting
- Highly detailed figurines and miniatures – Capture lifelike precision
- Jewelry prototypes – Intricate ring settings and fine engravings
- Architectural models – Scaled designs with high-resolution accuracy
- Medical and dental models – Detailed anatomical prototypes
- Product and engineering prototypes – Ergonomics and fine-tuned features
How MJP Printing Works
The Material Jetting process uses a printhead to deposit microscopic resin droplets:
- Liquid resin droplets are jetted onto the build platform
- UV light cures each layer instantly
- Support material prints simultaneously for fine features
- Wax support is melted away after printing
- Polishing enhances clarity and surface finish
MJP Materials and Finishes
| Material | Color | Properties |
|---|---|---|
| Crystal Ultra Fine Detail Plastic | Semi-translucent | Strong, rigid, slight yellow tint |
| Clear Ultra Fine Detail Plastic | Clear/translucent | Slightly softer, flexible |
| Tan Fine Detail Plastic | Tan | Stiffer, more brittle |
MJP Design Guidelines
| Design Feature | Requirement |

| Maximum bounding box (Clear/Crystal) | ( 290 \times 210 \times 100 , \text{mm} ) |
| Supported walls | ( 0.6 , \text{mm} ) |
| Unsupported walls | ( 0.8 , \text{mm} ) |
| Embossed/engraved details | ( 0.1 , \text{mm} ) |
| Minimum clearance | ( 0.05 , \text{mm} ) |
