Multi Jet Fusion 3D Printing Services

Multi Jet Fusion produces production grade 3D printed parts at high speeds with accuracy, perfect for functional prototypes and end-use parts.

mjf finishing solution

We run multiple materials on our MJF machines; primarily Nylon PA12 but also Nylon PA11 and BASF's Ultrasint TPU. All of our materials are production grade, meaning it is possible to replace the requirement for Injection Moulding (IM) for end-use products. Our range of materials means we can print for many properties and applications.

Our range of automated finishing equipment ensures that we can offer the full print to production workflow for almost every application possible. Our range includes vapour smoothing, vibro polishing & deep colour dying, all the way through to our spray booth and assembly, offering fully finished, repeatable parts, time after time. 

Vapour smoothing service

With the largest fleet of MJF machines in the UK and all the necessary finishing equipment we have significant throughput for any order on short lead times.

Our bulk discount pricing enables customers to see significant benefits from large production orders, even on a time crunch - enquire now how cost effective MJF can be!

Why choose Multi Jet Fusion Technology?

MJF is a 3D printing technology that uses a combination of heat, agents and specialised powders to create 3D objects. During printing, a bed of powder is first spread out over a build platform. An inkjet printhead then moves back and forth over the powder layer, depositing droplets of fusing agent that binds the powder together to create the desired shape. A heating element is then used to further sinter the powdered material, solidifying it into a fully formed object.

 

MJF is known for its high speed and accuracy, and is often used to create functional prototypes and end-use parts in a variety of industries, some common uses for MJF parts include:

 

Functional prototypes: MJF is often used to create functional prototypes for testing and evaluation. The high speed and accuracy of MJF allows designers and engineers to quickly and inexpensively produce prototypes that closely match the final product.

 

End-use parts: MJF can be used to produce production grade parts for a variety of industries, including aerospace, automotive, and healthcare. The high quality and durability of MJF parts make them suitable for use in demanding applications.

 

Customised parts: MJF allows for a high degree of customization, including the ability to produce parts with complex geometries and internal features. This makes it well-suited for producing custom parts with unique designs.

 

Batch Production: MJF can be used to produce batches of parts, making it a good option for production runs. Due to the powder based nature of MJF printing, it allows for parts to be nested around each other with no support material necessary, meaning we can optimise the full build volume for economic pricing.

 

Overall, the versatility of MJF makes it well-suited for a wide range of applications where high speed, accuracy, and durability are all critical.

PRODUCTION TIME

  • Minimum 2-3 Working Days
     

Our fastest production time for Nylon is 2-3 Working Days. This depends upon the size, quantity, quality of 3D data, and the production space available at the time of your request. We operate on a first come first served basis and have a cut off point at 3pm each day to begin collating and sending the data to the printers.

3D PRINTING PRICE

The cost of Nylon is primarily based on the overall height of the parts once they have been positioned to fit as low as possible within our maximum build chamber, with a small charge per any additional parts within that height. For multiple parts the cheapest and most efficient way is to use our Nylon Container System. For an estimate on a single part you can Contact Us and we will give you a quote.

DIMENSIONAL ACCURACY

  • +/- 0.35mm (+/- 35microns)

 

Generally our machines will print with a higher accuracy, they are calibrated up to ±0.15% on the X and Y axis and build with 0.1mm layers on the Z axis. We find that some shapes and forms can be more forgiving than others, depending on the overall size, form, density, and orientation. If you are working within these tolerances we recommend you contact us first to discuss your project.

SHELL THICKNESS

  • ~ 0.7 - 3mm (70 - 30 microns)

 

The outer shell thickness all depends on how you need to object to perform and function. Parts under 3mm may contain a degree of flexibility dependant on the shape support and structure. Anything above 3mm provides enough strength for all forms and sizes to remain rigid.

Escape Holes

Note:

It is important to remember that Nylon MJF is a powder based technology, meaning that powder can become trapped inside hollow parts if there is no hole to remove the powder from.

MAXIMUM BUILD SIZE

  • 380 X 380 X 284mm

 

For larger parts you may wish to reduce the scale of the object, or separate it into parts so it can be reassembled afterwards.

We would often recommend adding tapered location pins and corresponding holes with a clearance to accurately locate and connect parts afterwards.

TEXTURE DETAILS

The texture of Nylon has been accurately compared to a Extra Strong Mint, or a 320 grit sand paper.

This texture is a result of the outer grains of nylon powder adhering to the outer surface of the sintered Nylon.
All parts will have a grain of 0.1mm layers in the Z axis, which is often invisible to the eye and only becomes more visible on gradual curves. 

MINIMUM WALL THICKNESS

  • 0.8mm (80 microns)

 

Generally our machines will print with a higher accuracy, they are calibrated up to ±0.15% on the X and Y axis and build with 0.1mm layers on the Z axis. We find that some shapes and forms can be more forgiving than others, depending on the overall size, form, density, and orientation. If you are working within these tolerances we recommend you contact us first to discuss your project.

CLEARANCE BETWEEN PARTS

  • ~ 0.4mm (40 microns)

 

This is used to determine how close 2 objects or surfaces can be printed next to each other. If they are much closer than this, then the surfaces can begin to fuse together, distort or it may become impossible to remove the unsintered powder between the separate parts.

TRAPPED POWDER

Deep holes or recess’s can often create problems when removing the unsintered powder. We have techniques to avoid this before printing, so let us know if this is a concern and we can discuss it further with you.
