1. What is metal additive manufacturing (metal 3D printing)?


Metal additive manufacturing, also known as metal 3D printing, builds a three-dimensional object from a computer-aided design (CAD) model. It is built by adding metal powder material, layer by layer. This is completely different from conventional machining, casting and forging processes, where the material is removed from a stock item (subtractive manufacturing) or is poured into a mold and shaped using dies, presses and hammers.

2. What are the benefits of metal additive manufacturing (metal 3D printing)?


‍Metal additive manufacturing technology can produce very complex shapes or geometries with faster product development cycles, because components, shapes or tools are printed with metal powder in one step, instead of being assembled using multiple parts.

The benefit is:

  • Complex geometries can be manufactured
  • On-demand replacement for components
  • Increased speed and reliability of quality assurance and validation processes
  • Rapid prototyping to provide a dynamic, design-driven process
  • Reduced manufacturing lead times and increased productivity of critical components
  • Reduced component weights through innovative geometries and new patented materials
  • Stronger components with increased shear and tensile strength
  • Low volume production parts
  • Reduced development costs
3. Why use metal additive manufacturing (metal 3D printing)?

Components can be made with highly complex shapes (such as incorporating honeycombed internal structures) to reduce weight and cost.

This means that a component can be designed with a reduced mass or improved heat exchange characteristics compared with conventional casting, forging and machining processes. Best of all, metal additive manufacturing provides design flexibility.

4. Do you contract manufacture?

Yes, Amaero has a metal 3D printing manufacturing bureau service, which means we can manufacture components for you. Another option we provide is to connect you with other manufacturers who utilize our equipment, so they manufacture for you.  

Get in contact to find out more.

5. What metal 3D printing technique do you use for manufacturing components or tooling?

We use two techniques – Laser Powder Bed Fusion Selective Laser Melting (SLM) and Direct Laser Deposition (DLD) – also referred to as blown powder directed energy deposition.

The components are produced by selectively melting fine metallic powder layer upon layer using a high-powered laser which is scanned at high speed across each layer. These methods enable components to have highly complex shapes and can incorporate internal lattice structures to reduce weight and cost.

6. What post-processing applications do you use?

We use a variety of post-processing applications, including:

  • Heat Treatment
  • Stress Relieve
  • HIP (Ho- Isostatic Press)
  • A variety of finishes
  • ‍Abrasive Blast
  • Rumbling
  • Raw

We will use our expertise to apply the right post-processing application(s) for your project to ensure high quality.

7. What is tooling?

Tooling refers to the fixtures, tools and accessories that are used in machine tools such as CNC machines and injection molding machines, including jigs, dies, molds and patterns.

Agile tooling (or rapid tooling) is a growing application for metal 3D printing, where it is used to manufacture tools or tool components, or in producing molds which are then used to manufacture tools. This process significantly reduces the lead time and cost of tooling manufacture.

Additionally, the use of metal 3D printing improves functionality by creating tool designs that were previously unobtainable or unaffordable.

8. What metals can you print in your 3D printer for tooling and components?

Amaero has successfully printed many alloys. In fact, we have qualified more metals for the aerospace and defense industry than any other company in the world.

We print Aluminum alloys (AlSi7Mg, AlSi10Mg, Amaero HOT Al), Maraging steel (MS1), H13, 316 Stainless, 17-4 PH stainless, Hastelloy X, Hastelloy B23, Inconels (625, 718, 738) INVAR36, Cobalt Chrome alloys, Niobium alloys, Titanium alloys (Ti64, Amaero Beta Ti), Tungsten alloys and other specialized proprietary alloys on behalf of our clients.

Through our partnership with MCAM, we have patented two new superalloys for metal 3D printing (high strength titanium alloy powder and high-performance aluminum alloy powder) which offer significant benefits.

When it comes to your requirements use a specific alloy or develop a new one, we can provide you a solution.

When it comes to your specific project, we can help select an alloy that best meets your requirements.  Get in contact to find out more.

9. Your website mentions aerospace, defense and tooling industries. Can metal additive manufacturing (metal 3D printing) benefit other industries?


‍Yes, metal additive manufacturing (metal 3D printing) is beneficial for many industries, including:

  • Aviation
  • Space
  • Defense
  • Tooling
  • Automotive
  • Transport
  • Healthcare
  • Dental
  • Construction
  • Marine
  • Industrial

10. What components can be made with metal additive manufacturing (metal 3D printing)?

With the right material selection and manufacturing process, we can 3D print components that have load bearing durability requirements as well as decorative applications.

When compared to conventional manufacturing methods (forging, casting and machining), we can achieve more complex geometries and internal features such as cooling channels, lattice structures and parts consolidation.

The process is currently limited to a maximum build volume in a laser powder bed fusion of 800 x 400 x 500 mm, but the Direct Laser Deposition process can do larger components up to 4.5 x 1.8 x 1.5 meters.

There are software design tools that provide an indication of whether the design can be 3D printed. However, we recommend asking our team for feedback. We can confirm if there is a high or low risk of build failure and provide tips on how to avoid or mitigate these risks.

11. Do you manufacture components in polymers or composites?


No, we do not print with polymers. However, we have worked with clients to develop composites within a metal matrix. If you need plastic 3D printing, we can refer you to another company in our network.

12. What is the most cost-effective metal additive manufacturing machine to buy?


Our Amaero SP series range of machines are the safest and most capital efficient. The different range of sizes enables us to provide the most cost-effective solution for specific additive manufacturing requirements.

If you require small components, we have the SP100 with a build volume of 100 mm diameter x 80 mm Z. It is suitable for small components like dental implants or jewelry and is useful for research laboratories working on metal alloy development.

At the large end of the scale, we will soon have the SP800, which will be able to print up to 800 mm x 600 mm x 600 mm build volume. This is will be ideal for producing components for the aerospace and biomedical industries, as well as manufacturing steel tooling.

You may have read on our website that Amaero has purchased and optimized the parameters of their major competitors 3D printing machines.

In fact, some of these companies asked our team to provide new operating parameters because it out-performed what they were able to create.

13. How much do your machines cost?


Our prices are competitive, depending on the size of machine you require, Amaero SP series 3D printers are generally 1.5 to 2 times more capital efficient than our competitors.

This means on a capital cost recovery basis you can expect our machines to be half to two thirds of the price of the leading Laser Powder Bed Fusion Selective Laser Melting (SLM) 3D metal printers.
