The final components exhibit high-quality surfaces, fine details resolution and significantly superior mechanical properties when compared to selective laser sintering.

This guide provides insight into the capabilities and limitations of the 3D printing process. It's wonderful that we give a detailed overview of the entire procedure.

3D printing using Multi Jet Fusion – Explained –

The multi-jet fusion process is a relative newcomer to the 3D technology and manufacturing space. MJF is on the path to maturity on the scale and should be ready as soon as possible.

In this article, we will discuss the benefits and disadvantages of the technology and how to unlock its potential. How do you use 3D printing to get high costs for your printers?

We are happy to provide an overview of how MJF can be used to create a range of different types of 3D printers for a broad range of industries such as aerospace.

How does multi-jet fusion work?

HP Multi Jet Fusion [MJF] uses an inkjet array to selectively apply fusing agents over a bed of nylon powder following fusion into a solid layer via heating elements.

It is capable of producing functional nylon prototypes and ends end-use production parts within one day. This process also has more consistent mechanical properties than similar processes including selective laser sintering.

Protolabs produces non-filled Nylon 12 material commercially grade for building durability and lightweight parts.

Keep watching this brief video to learn the latest innovations in robotics. For well-designed parts tolerances could normally be 0.28mm plus -0.002mm/mm.

What is Multi Jet Fusion printing?

Multi Jet - Fusion is an additive manufacturing method invented & developed by Hewlett-Packard. It forms parts additively by using several agents printing.

Your plastic part will be made layer by layer based on your 3D model. Operators carefully remove the parts from the constructing box and remove the remaining powder through brushes and air blasters. In the print process, the parts are removed in the press and taken away.

The operationist safely removes the parts and removes powder from the Building Bag thanks to the air blowers. To finish the surface is exposed to the energy that leads to reaction amongst the agents and the material.

This HP Multi Jet Fusion technology prints each layer of a previously covered layer which is still molten - so both layers fuse completely. Unlike 3D printing, each layer is produced with liquid.

Thus they can create robust quality detailed, functional 3D printable parts. Imagine a future where we produce ‘smart parts’ with embedded electronics and integrated traceability and intelligence/traceability.

The technology can produce parts that cannot be made by other methods like that of 3D printers.

Technical Specifications

Minimum of 4 days depending on part dimensions, number of components and degree of finishing PA12: 0.3% (with a less limit of 0.3 mm) TPU 90A-01: 0.91.

Multi Jet Fusion parts can be sandblasted and coloured impregnated, sandblasting and/or flammable.

- Automotive

Printing MJF helps auto manufacturing save money on components production while supporting operational efficiency.

General Motors added 15,000 square feet to its additive industrial production facilities. It also includes an HP 2800 series Mk.1 printer in its 3D printing division.

Engineers have used HP Multi Jet Fusion in their production vehicles to make brackets and interiors.

General Motors says it will use HP's Multi Jet Fusion printing technology at the moment to print brackets and trim on production cars. On display is General motors' new additive industrialization.

- Feature resolution

MJF printers produce printed layers approximately 0.0003 inches thick with a minimum feature size of 0.02 inches (5.75mm) It can produce higher surface detail than others.

Protolabs'SLS series printers offer a superior low-speed small-series printer than MJF's. The printer could be printed up to 10 layers in thickness.

- Build volume

MJF trounces in printing processes with SLS, making it possible to produce many high-quality documents in the time taking for SLS to finish a document. In build volume, there's no competition.

- Part size

Multijet Fusion should still provide plenty of print size for most 3D printed components. Overall SLS is highest in parts with 2024 x 178 mm from MJF at 11.114.9 x 14.1 mm.

- Wall thickness

ML has a minimum thickness of 0.02 inches (0.15 mm), while SLS can produce walls as thin as 1.16 meters (1mm).

Materials for multi-jet fusion

Multi Jet Fusion is a kind of powder bed fusion that shouldn't mean all compatible powder bed materials will work with MJF.

Material producers responded to MJF's growing popularity. In 2020 HP worked with BASF on developing an innovative durable polypropylene.

In fact, the MJF material list is much younger than powder bed fusion, partly due to how the process operates properly, but material manufacturers are responding to the growing popularity of this material process.

New material continues to be developed in the Multijet Fusion processes between the HP and BASF HP.

The benefits of 3D printing and digital manufacturing during the Pandemic continue to grow while closing supply chains and improving the speed of design-to-production.

The medical and dental industries have experienced an explosion of new 3D printer applications and Mass Personalization. The SmileDirectClub has a 60 HP Multi Jet Fusion laser printer working around the clock to produce custom dental moulds.

This new fusion printer will also transform the 3D orthotics industry and enable the development of customizable medical products and solutions. OVR Technology develops devices that enable the use of smell primarily targeting medical and therapeutic fields. It.


Multi Jet Fusion - The big direct competitor within the powder bed print industry - is selective laser sintering (SLS). SLS fuses the layers with a directed laser beam.

The application requires ink jet-dispenses agents and heating elements.

SLS employs heated chambers within which individual material - powder layer can be consolidated to one without require of support for support.

The technology is similar to that of SLS which uses a laser beam to fuse layers of material together with the heat of the beam to create a powder bed.
