What Is MJF 3d Printing

Multi Jet Fusion (MJF) 3D printing represents a cutting-edge additive manufacturing technology, that excels in both high-volume production and precision. This innovative process involves applying a fusing agent and a detailing agent to a thin layer of powder, which is shaped according to the cross-section of the intended part at a particular layer height. A subsequent heat source triggers the fusion of the powder, transforming it into the desired final component.

After each fusion cycle, the print bed descends by the thickness of a single layer, commonly measuring 80 microns, and the entire process is repeated. This layer-by-layer approach allows for the creation of intricate geometries and the integration of multiple parts within a single build envelope, all without the need for support structures. This not only streamlines the production process but also significantly reduces costs.

MJF finds widespread application in various industries, including aerospace, medical, and consumer products. Its versatility enables the printing of watertight electronics encasements, robust under-hood automotive components, and personalized medical equipment like prosthetic limbs and dental implants. The technology's ability to handle complex geometries and produce multiple parts simultaneously positions it as a game-changer in the realm of additive manufacturing.

Why Choose Multi Jet Fusion 3D Printing

MJF parts exhibit a density comparable to that of plastic injection molded components, making them suitable for various applications. Their material properties allow for machining as required, ensuring that the final part meets specific performance standards. Furthermore, these parts can be drilled to create tiny holes that might otherwise be challenging to produce during the printing process.

When speed and precision are paramount, Multi Jet Fusion 3D printing is the ideal choice. This technology excels at producing highly detailed and dimensionally accurate features, ensuring that every aspect of the part meets the desired specifications. MJF 3D printers are capable of printing intricate features with widths as narrow as 0.1 mm, making them suitable for even the most complex designs.

HOFeng offers these post-processing services for MJF parts

Our Multi Jet Fusion (MJF) 3D printing process offers a remarkable improvement in surface finish, significantly reducing surface roughness from over 250 μin RA (as-printed) to a range of 64 – 100 μin RA after smoothing. This achievement is particularly noteworthy for PA12 Black material, which benefits greatly from this enhanced surface quality.

By smoothing the printed parts, we are able to attain a high-quality surface finish that closely rivals the appearance and feel of parts produced through injection molding techniques.
