3D Printing: MJF Multi Jet Fusion - Online Service

How does Multi Jet Fusion technology work?

Multi Jet Fusion (MJF) technology is a 3D dust-bed printing system developed by HP. Unlike SLS technology, this technology does not require a laser to sinter the material. A powder bed is deposited inside the print build and heated to a fixed temperature. A melting agent is deposited on these powders where the material will have to melt and a finishing liquid is deposited on the contours of the level to improve the resolution of the parts. Subsequently, the lamps slide over the level distributing the heat, the deposited agent absorbs the heat and helps distribute it evenly. This process is repeated for each level: in addition to guaranteeing the perfect adhesion of the layers, it allows for a fixed production time and a consequent reduction of costs.

Why choose Multi jet Fusion technology

Multi Jet Fusion MJF technology has immediately established itself on the market for its high level of innovation within additive manufacturing. In fact, for the first time, a 3D technology could produce parts in series of good workmanship, with excellent mechanical properties, a high rate of repeatability and in an economically advantageous way. From a design perspective, given that MJF technology does not require supports, the designer has total freedom, able to create complex geometries or linked objects. If traditional technologies such as injection moulding or extrusion remain valuable after amortizing the cost of the initial mould, MJF technology allows prototypes and runs to be made up to a thousand pieces faster and at a lower cost.
