Understanding MultiJet Modeling with HP Jet Fusion Technology
HP has made significant strides in the field of additive manufacturing with its MultiJet Modeling technology. This innovative process, launched alongside the HP Jet Fusion 3D 3200 and 4200 printers in May 2016, has revolutionized how 3D printing is perceived and utilized in various industries.
The Concept Behind MultiJet Fusion Technology
MultiJet Fusion (MJF) technology draws inspiration from traditional 2D inkjet printing methodologies. It operates within a powder bed environment, wherein a series of precise steps facilitate the construction of three-dimensional objects. This begins with the application of a binder through an inkjet print head, which diffuses two critical liquids: one that conducts heat and another that acts as a thermal inhibitor.
- Heat-Conducting Binder: This liquid significantly contributes to the binding of the material, ensuring that the printed object maintains structural integrity.
- Thermal Retardant: Applied to the edges of the object, this liquid controls the temperature of specific areas, enhancing detail and sharpness in the finished product.
Following the application of these binders, infrared energy sources are utilized to fuse the printed layers together, completing the formation of each component.
Comparative Analysis of HP Jet Fusion 3D Printers
The HP Jet Fusion 3D 3200 and 4200 printers, while visually similar, have distinct capabilities.
- Print Speed: The Jet Fusion 4200 boasts a higher print speed of 4500 cm³ per hour, compared to the 3200’s 3500 cm³ per hour.
- Accuracy Levels: The 4200 offers superior accuracy, capable of achieving up to 70 µm, whereas the 3200 ranges between 80 to 100 µm. Notably, the 4200 prints with a setting option of up to 120 µm for less detailed components.
- Cooling Features: An additional advantage of the 4200 series is its advanced cooling system, which reduces cooling times and allows for increased production throughput.
Despite these differences, both printers share common specifications, including an installation size of 406x305x406mm and a uniform print head resolution of 1200 dpi.
Advantages of MultiJet Fusion Technology
One of the impressive advantages of MultiJet Fusion lies in its utilization of the heat-retardant liquid, which results in a combination of sharp edges and high-quality surface finishes.
- Enhanced Component Properties: The prolonged application of energy sources during the printing process yields components with improved physical properties compared to other methods, such as Selective Laser Sintering (SLS).
- Surface Quality: The combination of the two binders enhances the overall aesthetic and functional qualities of the finished products.
Material Compatibility and Flexibility
MultiJet Fusion predominantly utilizes nylon-based materials, particularly PA12, which is specifically offered by HP. The technology is designed to be open, allowing users to experiment with a variety of thermoplastics, expanding material choices and enabling greater creativity in design and application.
Exploring the Potential of MultiJet Fusion
Professionals interested in the capabilities of MultiJet Fusion are encouraged to engage with the technology. Organizations like 3D Activation not only provide access to advanced printing services but also offer training courses to help users familiarize themselves with the technology, ensuring they can leverage it effectively for their needs.
