When to use MJP / PolyJet
- Very complex geometry and internal features
- Very fine details and smooth finish for display prototype
- Rubber-like or PP-like flexible material option
- Over-mould prototype
- Mechanical strength is not top priority*
- When budget is not a concern as material jetting is the most expensive option of all plastic 3D printing
*If both mechanical strength and finishing is important, consider using SLS with additional polishing and painting service
What’s the difference between MJP and PolyJet
MJP (Multijet Printing) is a proprietary technology of 3D Systems. This is an inkjet type of printing process where a print-head technology is used. PolyJet is a proprietary technology by Stratasys, its working is similar to that of MJP technology.
Both technologies have very similar specification in terms of accuracy. PolyJet usually offers a larger print size and more material selection. In addition, over-mould is possible on PolyJet with multiple material in one print.
Available materials for MJP
| Types | General considerations |
|---|---|
| M2R-WT | Smooth white finish, general purpose, moderate flex, like injection moulded plastic Basic machining application can be performed like drilling, tapping and metal inserts |
| M2R-BK | Black finish, higher tensile strength and modulus, harder and stiffer. Good for panels and thin-walled parts |
| M2G-DUR | PP-like, durability and pliability, good for living hinge application |
Available materials for PolyJet
| Types | General considerations |
|---|---|
| Vero White | Smooth finish, general purpose Basic machining application can be performed like drilling, tapping and metal inserts |
| Vero Black | Smooth finish, general purpose Basic machining application can be performed like drilling, tapping and metal inserts |
| Digital ABS | ABS-like, good temperature resistance and toughness Available in Grey / Black |
| Agilus Black | Flexible and tear resistance, black and rubber like. Other colour on request Available in 30 / 40 / 50 / 60 / 70 / 85 / 95 Shore A |
