The model is sent to software used by the printing machine.

Our machine specialist checks

all the geometrics are properly aligned and support structure are

in place within the build chamber.

DESIGN

The SLM (Selective Laser Melting)

process begins = The metal powder is fused into place with
a high powered laser.

As the laser hits the powder,

the powders melt and become

a solid mass.

The components are built up in layers usually 30 - 60 microns thick (which is approximately half the thickness of a human hair!) until the part is built. 

DESIGN

Excess powder is removed and reused, ensuring minimal waste which is good for the environment and very cost effective. 

 

Titanium 64


Titanium 64 is the most common titanium alloy used for medical and aerospace applications. It is hailed for its versatile, reliable and superior qualities. It boasts the highest strength to weight ratio of engineering metals, is extremely corrosion resistant and is one of the most abundant elements in the earth’s crust. Applications

  • Defence parts
  • Medical devices
  • Marine industry components
  • Industrial & specialty parts
  • Aerospace components
  • Sports & performance parts




Stainless Steel 15-5ph


Stainless Steel 15-5ph provides high strength, moderate corrosion resistance and good mechanical properties at temperatures up to 600oF (316oC). Stainless Steel 15-5ph is a hardenable stainless up to 48 HRC. This alloy is widely used in the aerospace, chemical, petrochemical, food processing, paper and general metalworking industries. Applications

  • Aerospace components
  • Engine parts
  • Fittings and gears
  • High pressure parts such as valves
  • Medical tools




Stainless Steel 316


Stainless Steel 316 has excellent corrosion resistance in a wide range of media. This makes it particularly desirable for applications where exposure to salt is an issue. It is mainly used in the food sector, marine and dairy industries. Applications

  • Boat fittings
  • Architectural components
  • Food and beverage processing equipment
  • Pharmaceutical and photographic equipment
  • Valve and pump parts




Inconel 718


Inconel 718 is a nickel super alloy used for high temperature applications used in a variety of industries such as aerospace, chemical processing, marine engineering, pollution-control equipment, and nuclear reactors. Applications

  • Defence components
  • Geo Thermal
  • Oil & Gas
  • Exhaust manifolds
  • Engine sumps
  • Jet engines




Aluminium (ALSi10Mg)


Aluminium (ALSi10Mg) is a typical casting alloy. Parts 3D printed in ALSi10Mg are ideal for applications that require a combination of good thermal properties and low weight. They can be machined, spark-eroded, welded, micro shot-peened, polished and casted if required. The laser powder bed 3D printing process produces parts that are similar to the T6 heat treated cast parts. Applications

  • Drone parts
  • Housings
  • Engine parts

OUR STANDARD FINISH

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).

 

HEAT TREATMENTS

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.

POLISHING OPTIONS 

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.
 

QUALITY CONTROL

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.

DESIGN

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.

3D PRINTING PROTOTYPES

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.

MOVING INTO PRODUCTION

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.
