HP MJF 3D Printing Service
HP Multi Jet Fusion (MJF) is a powerful 3D printing technology that produces highly accurate and durable parts at fast speeds, especially compared to other powder bed fusion technologies like selective laser sintering (SLS) or direct metal laser sintering (DMLS). Due to their affordability, speed, and high resolution, multi jet fusion technology can be used for end-use, low-volume production, rapid prototyping, or as a bridge process to injection molding. MJF allows engineers to get a feel for how parts will perform with minimal upfront costs.

Performance Finishes
Vapor Smoothing
Xometry can vapor smooth 3D printed parts to achieve an exceptional surface finish. Vapor smoothing, performed through AMT PostPro3D's technology, is a batch-based automated smoothing process that achieves a high-quality sealed surface with a semi-gloss appearance. Our color-dyed finishes can also be combined with vapor smoothing for additional customization options.
Cerakote
Cerakote is a polymer-ceramic composite coating engineered to improve physical performance properties such as abrasion, wear, corrosion, and chemical resistance, as well as overall surface hardness. The coating is applied by spraying it onto a part and curing it. The typical application thickness of both the C-Series and H-Series formulas is 0.5 to 1.0 mils (0.0005" to 0.001").

HP MJF Prototyping Tolerances
In the table below, you will find our standard MJF tolerances for prototype orders. These include one-off or first-time prints, non-production orders, and auto-quoted orders that have not received a manual engineering review.
MJF Prototype Tolerances Based on HP 5200-Series, Balanced Mode

Overview: What is HP Multi Jet Fusion?
The Basics of HP MJF
HP Multi Jet Fusion is a powerful 3D printing technology that produces highly accurate and durable parts that are capable of being used directly in end-use, low-volume production, or for rapid prototyping. Since the process uses well-established 2D printing ink-jetting, it has remarkably fast layer times compared to other powder bed fusion technologies.
How Multi Jet Fusion 3D Printing Works
Like all powder-based 3D printing processes, multi jet fusion technology builds parts layer by layer, using a fusing agent and heat to set each layer before moving onto the next. In the more traditional processes — such as Selective Laser Sintering (SLS), Stereolithography(SLA), or Direct Metal Laser Sintering (DMLS)— each part is imaged, layer by layer, with a single laser beam. HP’s Multi Jet Fusion works a bit more like a traditional ink-jet printer with a printhead that deposits the material, and then a fusing agent, across the entire build plate in one pass, allowing for the printing of multiple parts simultaneously.
The Benefits of HP’s Multi Jet Fusion 3D Printing Process
While there are many benefits to HP jet fusion, a few truly stand out. For starters, the standard build parameters are optimized for best density. The result is that Multi Jet Fusion parts are watertight.
If you like SLS but want to produce higher quantities for small-batch production runs, Multi Jet Fusion is the way to go. The ability to print multiple parts simultaneously across the entire build volume means you can print parts at rates up to 10X faster than SLS or other 3D printing processes. Also, Multi Jet Fusion delivers more balanced mechanical properties across the X, Y, and Z axes than SLS.
If you’re interested in injection molding for your project, it’s always a good idea to get a 3D printed “test” part before making the investment in metal molds. While SLA is a great 3D printing process for extremely detailed and high-resolution prints, the UV-cured resins are not as tough as traditional thermoplastics. Prints begin to degrade when exposed to UV light and moisture.
On the other hand, Multi Jet Fusion can produce accurate prints while also maintaining the structural durability of traditional thermoplastics, especially when using glass-filled nylon. This makes it an excellent process for testing fit and functionality before taking your project to injection molding.
