HP MJF stands for “HP Multi Jet Fusion” or “MJF”, which is a 3D printing technology developed by HP Inc. The technology was introduced in 2016 and has since gained popularity in various industries for its ability to produce functional parts and prototypes with a high level of accuracy and speed.
Now with an added advantage over Selective Laser Sintering (SLS) technology, HP MJF is a powder-based 3D printing technique. The main difference between the two techniques lies in the heat source, as the latter requires less heat in the process. While SLS utilises a laser to scan and sinter the material, HP MJF, on the other hand, does so through a new and innovative process that accelerates build time. This enables a finer feature resolution and a more consistent isotropic mechanical property. HP Inc. has reported that its MJF technology has printed more than 100million parts to date (as of 2022) across various industries, including automotive, healthcare, and industrial manufacturing.
During the HP MJF printing process, a fusing agent is applied to a material layer where the powder particles are supposed to fuse together. Simultaneously, a detailing agent that inhibits sintering is printed near the edge of the part. After this, a high-power IR energy source runs through the build bed and sinters the areas where the fusing agent was dispensed while leaving the rest of the powder untouched. The process repeats until all parts are complete.
Able to produce prototypes as fast as one day*, HP MJF is a great 3D printing solution for applications that require complex parts with geometries with fine features and functional end-use parts. Other benefits include:
Print speed: HP MJF is significantly faster due to its multi-agent printing process. HP MJF can print at a rate of several inches per hour, making it ideal for high-volume production.
Accuracy and precision: HP MJF can produce parts with a high level of accuracy and precision, thanks to its ability to selectively apply the fusing agent and detailing agent where they are needed.
Surface quality: HP MJF produces parts with a smooth surface finish due to its multi-agent printing process.
Material options: HP MJF can print with a range of materials, including PA12 (Certified Bio-Compatible), PA12 GB (Glass Beads), PA11, and TPU, among others.
Cost: HP MJF can be a more cost-effective for high-volume production, as it uses less material and produces less waste.
At Additive3D Asia, we are able to produce parts in house with a build volume of up to 380 x 284 x 380mm with HP MJF technology in Singapore. HP MJF can also create ultra-thin layers of 80 microns, which produces parts with high density and low porosity compared to the same PA 12 parts printed with SLS. In addition, the parts printed are stronger and more precise.
Overall, HP MJF is a powerful 3D printing technology that has helped revolutionize the way parts and prototypes are produced, making it an ideal choice for various industries such as automotive, aerospace, and healthcare, among others.

Short for Fused Deposition Modelling, FDM is one of the most commonly adopted additive manufacturing technologies today due to its low cost and efficiency.
Great for products that require a smooth finish and high accuracy. SLA is also a popular choice for creating prototypes for clear parts, including bottles.
SLS is a powder-based 3D printing technology suitable for building parts that require high durability and complex geometries as it does not need any form of support.
Similar to SLS, Multi Jet Fusion also utilises powder to 3D print objects. One advantage is that parts produced by MJF are stronger and more precise compared to SLS.
