3D metal printing is a revolutionary technology that produces impossible-to-make parts directly from your CAD data. Advantages to this process include the ability to produce strong and complex geometries, internal lattice structures, conformal cooling channels, and other features that cannot be made with traditional machining. Parts can be made quickly with a minimum of material waste making them ideal for next-generation engineering in aerospace, medical, automotive, and other industries.

With all subtractive manufacturing services available in-house through our AddSub® service, you can produce great results for the most demanding projects.

What is 3D Metal Printing?

At Star, we use a 3D printing process called Direct Metal Laser Melting (DMLM).  This additive manufacturing process uses a high-powered laser to melt and fuse successive layers of powdered metal into three-dimensional solid parts. The advantage is that the more complex or feature rich the component, the more economical the process becomes.

Advantages of 3D printing

There are many benefits for 3D printing, especially if you know how to develop your product design to take advantage of them. Benefits include:

  • 3D metal printed parts are fully dense, incorporating complex geometries and precise internal features that cannot be made with traditional machining alone.
  • Designs can be made quickly with a minimum of material waste while maximizing strength.
  • Conformal cooling channels greatly improve performance and resistance to thermal stress, ideal for aerospace and automotive applications.
  • Multiple, identical parts can be built on a single platform at one time, greatly increasing production efficiency.

3D Metal Printing Process

First a 3D CAD file must be provided for the design. We use specialized software to divide this drawing file into multiple cross-sectional layers, with each layer representing a 30μm thickness of the final shape.

In order to achieve the best results, it’s essential that our engineers review your CAD drawing file in advance and optimize the program wherever necessary. This may include adding support structures to areas where the force of gravity can cause features to distort during the printing process. These supports will later be removed.

At Star, we use a Renishaw’s AM250. This is a state-of-the-art 3D metal printer for rapid prototyping and manufacturing.


Currently we offer 3D metal printing in Titanium, Stainless Steel, and Aluminum. Each material has unique advantages relating to mechanical performance, weight, corrosion resistance and more.  There are also economic costs to consider, so our engineers are happy to advise you on the best materials for your application and budget.

Post Machining Services

3D metal printing almost always requires some form of post-machining to provide features that 3D printing alone cannot provide. Using our in-house AddSub® service this is a fast and easy process where material is removed by CNC milling and turning, drilling, or grinding. We also have a range of other finishing processes to ensure that you get the look you want.

Impossible Parts

Do you have a complex, convoluted impossible part design? Critical tolerances? We work with you to design your parts to suit our AddSub® manufacturing process to ensure you get the optimal solution for your impossible parts.

Rapid Delivery

Combining additive and subtractive manufacturing together in a single platform with one supplier saves time and streamlines communication to optimize your build.

Huge Savings

There is nothing more annoying or costly than having to compromise your critical part design to suit traditional manufacturing techniques. Combining 3D printing and machining can save time and money by simplifying the manufacturing process.

Metrology and Metallurgy

Inspection and metals testing is critical to ensure that your part is fit for purpose and able to pass your industry certification processes. STAR also has access to the world’s leading independent testing and certification bureaus.
