We mainly work with Product Developers who have a very clear idea, vision and design of the part that we can create with additive manufacturing and the SLM process. Most of our clients provide us with their designs in a CAD file but if you require design to be done, we can put you in contact with the right designers that will suit your specifications.

Talk to us early in the design process to determine whether 3D printing is suitable for the printing of your parts. Most of our clients provide us with their designs in a CAD file but if you require design to be created, we can put you in contact with a designer. We have been metal 3D printing parts for more than 10 years and are happy to look at your design and assist with design ideas.


Many of our clients start their 3D printing journey by printing a prototype; this is a good way to make and test their design and provide them with a completely functional part. With rapid prototyping our SLM 3D printing is able to bring a product to life quicker than ever. Metal 3D printing products come to life in unbelievable time frames.


We have a number of clients who were early adopters of metal 3D printing and understand the technology. This has allowed them to move into full-scale production of their parts using our 3D printing services. For the right products, this is a very cost-effective option.

Product developers and companies new to this advanced technology, metal 3D additive manufacturing process, can rely on our skilled, experienced team to guide you through the process.



Once the part has been 3D printed and the support material removed, the part undergoes a media blasting process. Media Blasting gives a more uniform finish and it suits most applications where the customer doesn't require a polished finish. We often compare the finish to the surface of a mandarin orange. It’s all in the finer detail with SLM (selective laser melting).



The metals we print can be treated in the same way as machined parts which means if there is a specific heat treatment you require, it is likely we can offer that on site in one of our furnaces.  For many of the parts, especially the 2000 parts we do for spacecraft each year, we do the heat treatment in argon even for Inconel and 15-5 stainless steel.  Doing this process in argon ensures that the parts do not have any oxide layers on the surface which helps for internal cavities etc and provides a cleaner and more reliable component.

All our Titanium printed parts are heat treated in order to:

  • Reduce residual stresses developed during fabrication (stress relieving)

  • Produce an optimum combination of ductility, machinability, and dimensional and structural stability (annealing)

We can also heat treat Inconel 718 and Stainless Steel 15-5ph; contact us for more information.


Vibratory Polishing

We take our standard finished part and put it into the vibratory polisher where it is immersed in mixed Ceramic media and left for a period of time, until it becomes polished. This process can take sharp edges off certain features.

Hand Polishing

This requires a hands-on approach involving grinding, linishing and hand sanding before moving on to buffing and polishing. Many parts are not suitable for hand polishing; this can be quite time consuming and is a more expensive option.


By focussing on the quality of the 3D prints we produce, we pride ourselves in a rigorous testing process to ensure your 3D print matches our quality control requirements. We’ve developed our own system which collects data on each build to ensure traceability. It has enabled us to understand the important factors influencing the selective laser melting process (SLM), from laser parameters to gas flow and powder quality.


From 3D printing design and prototyping to production we've put together a guide to the most frequently asked questions. Check this out here.
