3D Printing Materials

We have a vast range of plastic materials available for 3D printing. For visual prototypes (thermosets) using high detail resins to the creation of functional parts using thermoplastics.

Our range of 3D printing metals have applications in many industries. They are manufactured using the Binder Jetting printing or SLM/DMLS processes. Metal 3D printing has a wide range of uses in the design and manufacturing industries. You can select the best material for your project from the below options.


  • PLA provides excellent detail because of it's rigidity and is relatively inexpensive.
  • ABS has better thermal and mechanical properties than PLA and overall a good commodity plastic.
  • Resin provides quality detail, a very smooth surface finish. Resin offers an injection mold look.
  • Nylon is excellent for producing parts for functional injection molds as well as being resistant to chemicals.

  • PETG is thermoplastic polymer. An easy to use product used for mechanical parts, which handles high impact resistance and offers flexible ability.
  • TPU is very versatile and because of it's similarity to rubber can be used for producing seals, gaskets and in tube formation.
  • ASA is very useful because it's chemical and sun resistant, so great for outdoor applications.
  • PEI is plastic for high performance engineering applications and is fire retardant.
Get Started


  • Stainless steel gives you a high tensile strength also great corrosion resistance.
  • Aluminium is an excellent material and is relatively strong for its weight ratio. It has high machinability and ductility.
  • Titanium is extremely strong for it's weight and is routinely used in a wide range of industries such as aerospace, automotive and medical.

Surface Finishes

We can alter the surface of a manufactured part to change the appearance, chemical resistance, surface roughness and hardness of the produced parts by applying surface finishes after machining.
You can select the perfect finish for your 3D printing project from the following options:


Powder coating
Metallic spray painting
Plastic spray painting
Rubber oil painting
UV oil painting

Surface finishing

Sand blasting
Glass bead blasting
Brushing, Smoothing
Vapour polishing


Nickel, Zinc, Tin, Copper,
Silver, Gold

CNC Machining

CNC Milling is a machining process which employs computerised controls and rotating multi-point cutting tools to remove material from the workpiece. We have a wide range of the latest 3 axis, 3+2 axis and full 5-axis machines available.

CNC Turning is a manufacturing process in which material are held in a chuck and rotated while a tool is fed to the piece to remove material to create the desired shape.

Available Materials

Here is a list of our standard CNC machining materials available.

Plastics: ABS, Nylon 6, POM (Delrin), Polycarbonate, PVC, HDPE, Teflon and Peek.
Aluminum: 6061-T6, 6082, 7075 and 5083.
Stainless Steel: 303, 304, 316, 2205, Duplex and 17-4.
