3D Printing Technologies for High-Performance Engineering
Why the right technology matters
Choosing the right 3D printing technology is key to achieving the best balance of performance, cost and lead time. At Graphite Additive Manufacturing, we take a consultancy-led approach to every project, assessing your application, performance requirements and commercial objectives to recommend the process that will deliver the best overall result.
We go beyond standard machine settings by continually optimising our equipment, refining build parameters and developing proprietary material formulations to maximise strength, accuracy and surface finish. This includes SinterWorx G4 SLS, our own graphite reinforced material developed for demanding engineering applications. Combined with rigorous calibration and quality control processes, we deliver consistent, repeatable results for everything from one-off prototypes to low-volume production runs.
Our 3D printing technologies

Multi Jet Fusion (MJF)
MJF delivers exceptional consistency, excellent surface quality and fast production speeds, making it an ideal choice for low-volume manufacturing and production-ready components.
Best for:
- Production parts
- Excellent surface finish
- Repeatable manufacturing
- Low-volume production
Stereolithography (SLA)
SLA produces highly detailed parts with smooth surface finishes, making it ideal for visual prototypes, wind tunnel testing and applications where appearance and precision are essential.
Best for:
- High-detail prototypes
- Smooth surface finishes
- Wind tunnel models
- Composite tooling
Selective Laser Melting (SLM)
SLM enables the manufacture of complex metal components with outstanding mechanical properties, making it suitable for demanding engineering applications where strength and weight are critical.

3D printing technology FAQs
What is the difference between SLS and MJF?
Selective Laser Sintering (SLS) and Multi Jet Fusion (MJF) are both powder-based 3D printing technologies capable of producing strong, functional parts without the need for support structures. The main difference lies in how each process builds the part.
Selective Laser Sintering (SLS) uses a laser to fuse layers of polymer powder, making it an excellent choice for complex geometries, functional prototypes and durable end-use components. Multi Jet Fusion (MJF) uses fusing and detailing agents with heat to produce highly consistent parts with excellent mechanical properties, dimensional accuracy and repeatability, making it ideally suited to functional prototypes and low- to medium-volume production.
At Graphite Additive Manufacturing, we assess your application, performance requirements and production volumes to recommend the technology that will deliver the best overall result.
Which 3D printing technology is strongest?
The strongest 3D printing technology depends on the application and the material being used. For robust plastic components, SLS and MJF both produce parts with excellent mechanical properties suitable for demanding engineering applications. Where metal components are required, Selective Laser Melting (SLM) produces fully dense metal parts with exceptional strength and durability.
Graphite also develops proprietary material formulations, including SinterWorx G4 SLS, a graphite reinforced material designed to enhance performance for demanding engineering applications. Our team will recommend the most suitable technology and material based on your project’s functional requirements.
Which process provides the best surface finish?
For applications where appearance, fine detail and smooth surface finish are the priority, Stereolithography (SLA) is typically the preferred choice. SLA uses a UV laser to cure liquid resin layer by layer, producing highly accurate parts with excellent surface quality and tight tolerances.
For powder-based technologies such as SLS and MJF, additional finishing processes like vapour smoothing can be used to significantly enhance surface quality. Vapour smoothing works by chemically treating the surface of the part to create a sealed, smooth finish, improving both appearance and performance by reducing porosity and making parts easier to clean.
This makes SLA ideal for presentation models, master patterns, detailed prototypes and applications where visual quality is just as important as dimensional accuracy, while vapour smoothing offers an effective way to achieve similar surface improvements on functional nylon parts.
Which technology is best for production parts?
There is no single technology that is best for every production application. The most suitable choice depends on factors such as quantity, material requirements, mechanical performance and the operating environment.
MJF is often selected for production parts because it delivers excellent consistency, repeatability and surface finish across both low and higher production volumes. SLS is also widely used for end-use components where strength, durability and complex geometries are important.
At Graphite Additive Manufacturing, we review every project individually to recommend the technology that offers the best balance of performance, quality and commercial value.
Can Graphite recommend the right 3D printing process?
Yes. Choosing the right technology is a key part of our consultancy-led approach.
Rather than simply selecting a machine, we assess your application, performance requirements, production volumes, budget and timescales before recommending the most appropriate additive manufacturing process. We continually optimise our equipment, refine build parameters and develop proprietary material formulations to maximise strength, accuracy and surface finish.
Our goal is to recommend the solution that best meets your project’s requirements, not simply the equipment we have available.
