Industrial 3D printing of functional, end use nylon parts

HP Multi Jet Fusion (MJF)

HP MultiJet Fusion (MJF)

Our industry leading in-house HP Multi Jet Fusion 3d printing service operates from our dedicated production facility providing batch production and prototyping.  We chose the HP MJF machine over the more common SLS 3d technology as it was designed from the ground up for the huge growth in 3d print manufacturing offering both speed and efficiency for industrial scale additive manufacturing.  Trusted by industry leaders like Jaguar Landrover and BMW, HP Multi Jet Fusion from Midlands 3D provides the very best in 3d printed components.

With these machines, we are able to provide the fastest turnaround, lowest possible unit price and a more accurate and robust part than SLS alternatives.  Whether you require a one-off prototype or large batches of end use parts, our manufacturing facility can provide strong, accurate and durable parts, primarily using Nylon PA12.

“With Multi Jet Fusion technology, the material is fully fused, creating fully dense parts with high mechanical properties”

Why use MJF 3d printing?

MJF is a popular choice for 3d printed functional parts over more common processes such as SLS due to….

Increased Strength – An MJF part is isotropic meaning it has strength in all three axis, unlike SLS or FDM where weakness in the Z axis is a result of the production process due to the print process.  An MJF layer of nylon is fully melted with every layer whereas SLS or FDM are melted only at a molecular level.

Uniform finish on all surfaces and exceptional detail for powder bed fusion parts – Whereas an FDM print requires support material for overhangs, which is subsequently removed leaving a degraded underside surface, MJF parts are created encased in powder which is removed as part of the post procesing stage.  The fine powder leaves a surface finish consistent with the whole part.

Deep colouring of the part – MJF parts are naturally grey when removed from the machine, but can be vapour smoothed or dyed black with significantly deeper penetration than the 0.2mm (max) of a normally white SLS print.

Speed for volume production capability – HP design the machine and related workflow specifically for the manufacturng process and not just one-off prototyping meaning the cost savigs of a fast and efficient print process can be passed on to our customers.
