MultiJet Printing (MJP) / Wax Jet Printing
Description
MultiJet Printing (MJP), also known as Wax Jet Printing, is a high-resolution additive manufacturing process that uses photopolymer or wax-like materials. It operates by jetting microscopic droplets of material layer by layer, which are then cured using UV light. This technology is excellent for producing detailed prototypes, casting patterns, and tooling masters with exceptional surface quality and accuracy.
Materials Available
- VisiJet M2 ICast (Wax)
- VisiJet M2 SUW (Rigid Plastic)
- VisiJet M3 Crystal (Translucent Plastic)
- VisiJet M3 Black (Opaque Plastic)
- VisiJet M3 ProFlex (Flexible Material)
- VisiJet M3 X (Tough Plastic)
Technical Details
- Layer Thickness: 16 to 32 microns depending on the model material.
- Dimensional Accuracy: ±0.05mm or better depending on geometry and size.
- Surface Finish: Smooth; typically does not require post-processing.
- Max Build Volume: Approximately 294 x 211 x 144 mm (depending on machine).
- Support Material: Wax-based and easily removed with heat or solvent.
Cost
- Initial Capital Investment: Medium to high depending on machine configuration.
- Production Costs: Moderate, lower than metal additive processes.
- Operational Costs: Includes resin or wax cartridges and routine printhead maintenance.
Advantages
- Produces ultra-smooth, precise, and detailed parts directly from CAD.
- Ideal for investment casting patterns, dental and medical models, and jewelry masters.
- Minimal post-processing; supports melt or dissolve cleanly.
- Works well for assemblies that require tight tolerances.
Disadvantages
- Limited material choices compared to FDM or SLA.
- Part mechanical strength is lower than thermoset or metal prints.
- Not suitable for high-temperature or structural applications.
