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.

Materials

MJF

PA12

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.

Other 3D Printing Processes

FDM

Short for Fused Deposition Modeling, FDM is one of the most commonly adopted additive manufacturing technologies today due to its low cost and efficiency.

SLA

Stereolithography was first developed in the 1980’s. The process is often used when a smooth finish and high accuracy is required.

Polyjet

Polyjet is a liquid-based 3D printing technology. It is able to 3D print at a high speed, with extremely high accuracy and a smooth surface finish.

SLS

SLS is a powder-based 3D printing technology suitable for building parts that require complex geometries and high durability.

Full Colour

Full Colour 3D UV-Curable Inkjet technology has the capability to print 10 million colours, making it ideal for products such as marketing models.
