Question 1

HOW DOES MULTI JET FUSION WORK?

Accepted Answer

Multi Jet Fusion (MJF) operates by spreading a fine layer of nylon powder within the build chamber. The MJF 5210 3D printer uses print heads to jet detailing and fusing agents onto the powder, creating a 2D cross-section of the desired part. Heat lamps then activate the agents, fusing the PA12 nylon powder into a solid layer. This process repeats, adding new layers of powder to build the 3D part layer by layer.

Question 2

ARE MULTI JET FUSION PA12 NYLON 3D PRINTS WATERTIGHT?

Accepted Answer

Yes, 3D prints produced using HP Multi Jet Fusion technology are nearly watertight right after printing. They typically do not require additional post-processing to achieve a high degree of water resistance.

Question 3

WHAT IS THE DIFFERENCE BETWEEN SELECTIVE LASER SINTERING (SLS) AND MULTI JET FUSION (MJF)?

Accepted Answer

The primary distinction between Selective Laser Sintering (SLS) and Multi Jet Fusion (MJF) lies in the method of fusing the powder material into parts. SLS employs a laser for this purpose, while MJF uses agents and heat lamps. Notable differences include the natural grey colour of MJF 3D prints compared to the white colour of SLS 3D prints. Additionally, these technologies utilise different pricing algorithms. For a more detailed comparison, you can refer to our blog post on Selective Laser Sintering (SLS) versus Multi Jet Fusion (MJF).

Question 4

WHAT ARE THE ADVANTAGES OF MULTI JET FUSION OVER OTHER 3D PRINTING TECHNOLOGIES?

Accepted Answer

Multi Jet Fusion (MJF) offers several advantages over other 3D printing technologies. These include high speed, precise printing, the ability to produce functional and durable parts with excellent mechanical properties, and the capability to create parts with fine details and complex geometries. Additionally, MJF typically results in minimal post-processing requirements.

Question 5

WHAT INDUSTRIES AND APPLICATIONS ARE SUITABLE FOR MULTI JET FUSION?

Accepted Answer

Multi Jet Fusion is suitable for a wide range of industries, including aerospace, automotive, healthcare, consumer goods, and more. It can be used to produce prototypes, end-use parts, custom medical devices, and various components in industries that require precision and durability.

Question 6

WHAT IS THE RESOLUTION AND LAYER THICKNESS ACHIEVABLE WITH MULTI JET FUSION?

Accepted Answer

The resolution and layer thickness achievable with Multi Jet Fusion can vary depending on the settings. Generally, MJF achieves a layer thickness of 0.08 millimetres (80 microns), allowing for high-quality and detailed 3D prints. At Precision 3D Prints we only print on the finest layer height possible with MJF.

Question 7

ARE THERE ANY SIZE LIMITATIONS FOR PARTS THAT CAN BE PRODUCED USING MULTI JET FUSION TECHNOLOGY?

Accepted Answer

While Multi Jet Fusion technology is versatile and can produce parts of various sizes, there may be limitations based on the MJF printer's build volume. The maximum size of parts that can be produced are 370 x 370 x 270mm however we wouldn't recommend printing parts this size if your component requires tight tolerances, or an even surface finish.
