What is MJF?
Multi Jet Fusion is a relatively new 3D printing technique unveiled by HP in 2016.
Similar to Selective Laser Sintering (SLS) technology, 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.
During MJF, a fusing agent is applied on 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. Afterwhich, 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.
We are able to produce parts with a build volume of up to 380 x 284 x 380mm with MJF technology. 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, parts printed are stronger and more precise.
PA12 is an engineering grade thermoplastic that produces high-density parts with extreme dimensional accuracy and fine detail for functional prototyping and final parts. It is ideal for complex assemblies, lattice structures, housing, enclosures and connectors, and optimal for post finishing processes.
3D Printing Processes
Short for Fused Deposition Modeling, 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.
Capable of printing multiple materials from flexible to rigid in one part. 3D prints at a high speed, with extremely high accuracy and a smooth surface finish.
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 utilizes powder to 3D print objects. One advantage is that parts produced by MJF are stronger and more precise compared to SLS.
