Overview
AMufacture is the UK’s leading production partner specialising in HP Multi Jet Fusion (MJF) printing.
This fast 3D printing method produces durable, functional parts with excellent mechanical properties and fine surface details. For our collaborators, that means production-ready outcomes at minimal cost and optimal speed and scale.
Key Properties
Fast
With unrivalled speed and consistent, volume-independent lead times, MJF yields scalable production with no costly tooling and all the freedom of rapid, iterative development.
Efficient
MJF is fundamentally designed to be economical and ecological. It allows for production at scale with cost-effective material reuse and almost zero waste.
Collaborative
We become your end-to-end production partner. Harness cross-industry expertise and best-in-class MJF 3D printing technology, from design optimisation to post-processing.
What is Multi Jet Fusion (MJF) 3D printing?
HP’s Multi Jet Fusion is considered the industry standard for powder bed fusion (PBF) printing. It combines inkjet-deposited fusing agents and detailing agents with infrared light to selectively fuse thermoplastic powder layer by layer.
Unlike selective laser sintering (SLS), which traces each cross-section with a laser point, MJF applies agents across an entire solid layer simultaneously. It then fuses treated areas with a heat source passing over the build chamber.
The process delivers consistent isotropic mechanical properties, meaning tensile strength and impact resistance remain nearly uniform across all axes. This makes MJF-printed parts predictable for engineering applications where directional strength matters.
HP introduced Multi Jet Fusion commercially around 2016, evolving it from rapid prototyping into genuine production runs. MJF 3D printing has advanced the additive manufacturing industry through an efficient, scalable and sustainable manufacturing method.
Primary plastic materials include PA12 nylon powder, PA11, TPU for flexible applications, and glass- or mineral-filled nylons for enhanced stiffness and thermal performance.
Why Manufacturers Choose MJF For Functional Parts
MJF printing is at the bleeding edge of additive manufacturing, quickly producing parts with excellent mechanical properties and fine feature resolution.
Combined with AMufacture’s best-in-class manufacturing capabilities and end-to-end, real-time production visibility, this allows for fast, scalable and repeatable production runs without the tooling costs and lead times of injection moulding.
The UK’s Leading MJF
Production Partner
AMufacture goes beyond contract manufacturing. When you partner with us, our industry-leading technologies and expertise become an extension to your workflow, enabling fast, consistent and repeatable production at scale.z
True Collaborators
Our partners enjoy expert support through every stage of the MJF production process. We’re strategic collaborators, working with clients across design, production and post-processing to optimise efficiency, quality and value.
Best-in-class Technology
At AMufacture, we constantly advance our capabilities to meet and exceed your requirements. We are the first UK contract manufacturer to operate the HP 5420W 3D Printer, capable of producing engineering-grade white parts.
Digitally Transformative
Let our digital platform be your single source of truth. As an AMufacture partner, you can track your parts in real time through every stage of production and build an IP-secure Digital Warehouse for seamless reordering and iteration.
Unrivalled MJF Printing Technologies
At AMufacture, we advance our capabilities to keep pace with the most demanding industry requirements. That includes investing in bleeding-edge Multi Jet Fusion 3D printing systems that support fast, flexible and automated production.
- 1 x HP 5420W printer – a UK contract manufacturing first, this system allows for the production of consistent, engineering-grade white parts at speed and scale.
- 4 x HP 5620 printers – the backbone of the fleet, these proven MJF production platforms deliver scalable manufacturing capacity for high-volume, production-ready parts.
- 2 x BB8 systems – fitted to our HP 5620s, these innovative automatic changeover systems enable 24/7 manufacturing with no operator involvement.
Post-processing Capabilities
Partners from the first enquiry to the perfect finish
A key benefit of MJF printing is its minimal post-processing requirements. However, some finishing is typically required for refinement and performance optimisation.
As your end-to-end production partner, AMufacture offers a wide range of in-house finishing capabilities to take your assemblies to the next level. Our services range from ISO-certified dyeing to full technical assembly. For MJF components, the most beneficial secondary operations include:
- Surface finishing: including bead blasting to remove powder and create a matte surface, vibro polishing to smooth edges, and vapour smoothing to seal pores and enhance strength.
- Assembly: compatible methods include snap-fits (0.2 mm clearance), press-fits (±0.3% tolerance), threaded/heat-set inserts, adhesive bonding and ultrasonic welding.
Cross-industry Expertise
AMufacture’s HP 3D printing services support partners across industry verticals to scale production, accelerate innovation and ensure compliance. We help clients deliver against complex briefs and create end-use parts for a wide range of industry-specific applications.
Frequently
Asked Questions
How much quicker is MJF compared to other technologies?
MJF offers faster turnaround times compared to Fused Deposition Modelling (FDM) and Stereolithography (SLA). It can produce parts up to ten times faster than comparable FDM and SLS systems, according to internal testing by HP.
Is MJF heavy on post-processing?
Layer-wide fusion delivers uniform thermal distribution, ensuring consistent mechanical properties across all axes. That includes minimising Z-axis weakness – a common challenge with SLS printing.
What happens to the excess powder?
Layer-wide fusion delivers uniform thermal distribution, ensuring consistent mechanical properties across all axes. That includes minimising Z-axis weakness – a common challenge with SLS printing.
How is MJF different to home 3D printing?
Layer-wide fusion delivers uniform thermal distribution, ensuring consistent mechanical properties across all axes. That includes minimising Z-axis weakness – a common challenge with SLS printing.
