MJF MultiJetFusion: 14 models

MJF, Multi Jet Fusion, is the polymer powder bed process developed by HP. One carriage spreads a layer of polyamide powder, a second carriage carrying thermal inkjet heads prints a fusing agent onto the part areas and a detailing agent along the contours, and infrared lamps then fuse the wetted regions across the whole bed in a single pass. There is no laser, so layer time does not depend on the number of parts. Materials are PA 12, PA 12 GB, PA 11, TPU and PP; the 580/540 series prints in full color. Parts are dense, mechanically robust and dimensionally accurate, grey to anthracite in color, and are usually bead-blasted, dyed or smoothed. The process is designed for series production and competes directly with SLS.

The catalog contains the first-generation Jet Fusion 3200 and 4200/4210, the 5200, 5210 and 5210 Pro, the current 5600 and 5420W, the compact Jet Fusion 300/500 and the color systems 580 and 540. The 4200 and 5200 are common on the used market, typically as a cell including a processing station and two or more build units.

When buying a used MJF system, the combination is what counts: printer, build unit and processing station form one system, and the printer alone cannot operate. Check print head age and condition (a counted wear item), fusing lamp hours, the state of the build units (heating, sieve module), the lock-in to HP-certified powder and chipped agents, the validity of software and service contracts, and the utilities for power, compressed air and extraction. The HP peripheral equipment (build units, processing stations, cooling and unpacking) is listed under post-processing equipment. Below you will find the technical data of all 14 MJF models in our catalog, together with those currently offered second-hand.
