Hewlett-Packard (HP) is one of the leading innovators of printing technology. One of its contributions to the manufacturing industry is multi-jet fusion (MJF), an additive manufacturing technology that builds high-quality nylon parts suitable for prototyping or end-use production. With MJF 3D printing, you can produce black or full-color parts, depending on your requirements. As such, it reduces post-processing time and manufacturing costs for faster turnaround.
Common applications and materials
Multi-Jet Fusion can produce parts that require uniform isotropic mechanical properties. Material options add to the versatility of the 3D printing process in delivering functional prototypes and organic and complex geometries with finer features.
High tensile strength PA 12 generates final parts in black, with quality surface finishes. Black nylon parts have slightly greater isotropic mechanical properties compared to those produced by SLS 3D printing. The material can also realize smaller feature resolutions, making it suitable for designs with living hinges. Reputable manufacturers can finish the black nylon parts after MJF 3D printing using sandblasting, painting, or smoothing.
Benefits for your project
Multi-jet fusion is scalable to meet your production requirements, whether you require a single part or multiple virtually identical components. It delivers the results fast, usually in three to four days, when provided by an experienced manufacturer. This way, the process can reduce your time to market and speed up your design iterations. MJF 3D printing can build complex geometries without additional costs. It can also deliver end-use parts on demand to increase your throughput.
Choose the right 3D printing partner.
The success of MFJ 3D printing depends on your design and the service provider. Reputable rapid prototyping companies can recommend design tips for an effective manufacturing process. For instance, they could advise you to maintain consistent size and thickness, as anything exceeding seven inches and thin features are prone to warping. Manufacturers follow the best practices and apply proven tolerances for accurate production.
