Under the circumstances in which speed has become an evident determining factor of competitiveness, the development of prototyping tools has also acquired special significance. One such change is, for example, the multi-jet fusion (MJF) of 3D printing produced by HP. Simply put, it has redefined 3D printing with unparalleled speed, accuracy, and versatility. This paper examines how HP MJF technology transforms the modeling field and equips specialists with methods that shorten the time of product launch, reduce costs, and expand the design’s creativity. In addition, the technical details of the MJF technology will be described, compared with other methods, and applied in some sectors.
What is HP Multi Jet Fusion Technology?
HP Multi Jet Fusion (MJF) is considered a new evolution in the 3D printing process, wherein finer materials and HP’s developed fusing and detailing technologies are dispensed and built one layer at a time to achieve high-caliber parts. In contrast to the conventional 3D printing approaches, which rely mostly on single-point deposition, MJF involves multi-agent printing, starting with powdered fine thermoplastic spread evenly across a build platform and selectively melting using heat. This feature improves the printing velocity and the final product’s properties and surface quality. That technology is very flexible and creates accurate and complex shapes thus, suitable for many industries.
Understanding the 3D Printing Process
HP Multi Jet Fusion, 3D printing technology, differs from others in that it can produce assembled parts quickly and easily utilizing a distinctive procedure. Unlike some other methods of 3D printing, where the only method of deposition is a single point, MJF has a multi-agent printing process. A thin layer of the powder to be used as the build material is spread on the build surface, after which a fusing agent and a detailing agent are selectively jetted onto the powder bed. Energy is then delivered to this area through infrared rays, which sinters the powder that was covered with treated areas. The same rutal process continues to build layers until the shape is complete, giving rise to parts of good mechanical properties, high resolution, and smooth surface for finishing. Most of MJF’s capabilities are attributed to the ‘engineering’ and ‘designing’ industries, as it is possible to manufacture complicated forms with little further processing into the finished product, which is highly needed in automotive or healthcare.
How HP Jet Fusion Technology Works
HP Jet Fusion Technology has consistently performed well, working in well-defined sequences of procedures. Initially, a thin layer of powdered material is uniformly spread across the build platform. After that, two agents are used on the surfaces of the powder bed: a fusing agent and a detailing agent. These agents are accurately squirted on the powder on which the agents are to be solidified. Then, infrared heat is focused on the powder treated by the agents, which leads to the agents melting and joining together. This cycle is scrupulously done from one layer to the other until all the volume is filled by the part that has been built. Such manipulation of the powder material saves the operator a great time since only accurately fitting and strong parts with delicate features and nice finishing are produced.
Key Features of HP Multi Jet Fusion

How Does HP Jet Fusion 3D Printing Technology Compare to Other Technologies?
MJF vs. Selective Laser Sintering (SLS)
The Multi Jet Fusion (MJF) as well as the Selective Laser Sintering (SLS) are two advanced 3D printer technologies utilized for industrial purposes, but their particularities delineate what projects can be executed with success.
Print Speed: SLS typically takes longer than MJF because SLS technology needs time to lay down material and fuse it to accomplish a certain layer.
Detail and Surface Finish: As with every other finished part, MJF will usually retain finer detail and smoother finishes directly from the printer, as opposed to SLS, which cuts and sculpts the surface, especially post-processing.
Material Range: While MJF and SLS can utilize many materials, SLS is more flexible to multiple materials, metals and thermoplastics than MJF, which mainly accepts polymers.
Cost-Effectiveness: Due to reduced processing times and the production of fewer HM MJF components, it becomes cheaper to prototype and run a few small and medium production runs that use Munson and Associates HP MJF.
Thermal Properties and Strength: Generally, SL S parts have better thermal and mechanical properties than the produced parts; hence, parts applied with MJF technology cannot be used in critical mechanical and thermal conditions.
Thus, by studying these attributes, companies will be able to make a better choice as to which of these technologies would suit their specific needs by either focusing on MJF speed and surface quality or SLS material versatility and structural strength.
Comparing MJF with Powder Bed Fusion
Powder Bed Fusion (PBF) has different meanings when it comes to the use of Selective Laser Sintering (SLS) and Direct Metal Laser Sintering (DMLS), which have emerged as another form of additive manufacturing. When comparing MJF and PBF, noticeable differences occur while analyzing these techniques.
Print Speed: MJF is generally faster in terms of printing speed than other techniques, as it continues to add and bond materials throughout the process. For PBF techniques, such as SLS, this can be relatively slow as sintering is done layer by layer.
Surface Finish and Detail: As a result, MJF provides better surface quality and finer details as printed, eliminating the need for excessive secondary operations. In these processes, good-quality parts can be manufactured; however, the overall quality of the surface can mostly be attained after many secondary operations have been performed.
Material Versatility: PBF is more than flexible, allowing the use of different materials such as polymers, metals, and ceramics. It can be noted here, however, that those materials are primarily polymers for MJF.
Cost: On the other hand, it is perhaps the most efficient and cost-effective method for parts that need to be prototyped or produced in small to midsize batches due to short build times and less material wastage. The PBF processes might be some of the most expensive to run, especially with metal powders, but they give the best mechanical properties.
Mechanical Properties: PBF methods, particularly metallic-based parts produced using these methods, have excellent mechanical properties and thermal resistance. MJF parts are strong and functional components, although they are usually outperformed by metal parts produced by PBF when it comes to mechanical properties.
From a business perspective, considering such factors enables MJF or PBF selection depending on speed, surface finish, variety of materials, or strength of the final part, among other things.
Differences Between MJF and Metal 3D Printing
Speed and Efficiency
MJF (Multi Jet Fusion) technology stands out in speed and efficiency because it has a continuous deposition and fusing process. This enables the rapid part production of HP MJF and is ideal for more prototyping and small to mid-sized production runs employing HP 3D high reusability approaches. As opposed to this, in metal 3D printing, especially those that employ most of the Powder Bed Fusion (PBF) methods, the general process of layer upon layer of sintering or melting of metals is very time-consuming per layer and so stand a chance of prolonging the whole production cycle.
Surface Finish and Detail
As regards surface finish and detail, MJF usually has better part quality straight off the printer with less demand for additional work than metal 3D printing parts. Metal 3D printing is also capable of producing quality parts; however, such parts often require a lot of post-processing to achieve such surface finish and detail.
Material Variety
MJF is mostly limited to the use of polymer parts and hence has fewer material options regarding variability. On the contrary, metal 3D printing is very broad in terms of the type of metal or metal alloy that is deposited, making it useful for a larger range of applications.
Factors impacting costs
Cost efficiency is one of MJF’s advantages, considering that it is ideal for small to mid-size production runs and prototyping on account of its low lead times and minimal material wastage. Metal 3D printing skips these drawbacks as it offers excellent material properties but comes at a hefty price, as most expenses are incurred in acquiring metal powders and the operations involved.
Mechanical Properties
Here, high-performance parts with high thermal resistance are produced, which usually denotes tough parts suitable for most industrial use. Parts produced from MJF are sturdy and usable but usually lack the mechanical strength and precious heat resistance of parts made with metal 3D printing technologies.
Notably, in terms of MJF vs. metal 3D printing, the choice is taken based on how the concerned applications were defined, addressing mainly speed, surface finish, available materials, costs, and mechanical characteristics.
