Metal Additive Manufacturing


Design freedom

LPBF allows for the realisation of highly complex geometries that traditional manufacturing methods simply cannot achieve.


Complete Consolidation

LPBF can repeatably produce 100% dense components, setting it apart from other sinter-based technologies; it also yields unique microstructures that can deliver superior mechanical performance to wrought or cast components.


Greener Manufacturing

By minimising waste through additive rather than subtractive methods and enabling localised production, it eradicates the need for worldwide shipping of components. In our case we use 100% zero-carbon energy sources as well!


Digital Inventory

Manufacturing using LPBF significantly reduces lead times and reduces or even eliminates the need for warehousing, as parts can be efficiently printed on demand from a curated digital repository.

Metal Additive Manufacturing

What is Metal Additive Manufacturing?

Laser Powder Bed Fusion (LPBF) stands as a preeminent technology in the field of Metal Additive Manufacturing. Also known by various acronyms such as DMLS (Direct Metal Laser Sintering) and SLM (Selective Laser Melting), the LPBF process involves spreading a layer of metal powder over a build plate and selectively melting it using a high-energy laser beam. The process is then repeated layer by layer until the desired component is realised.

At Apex, we’ve mastered the added complexities of using multiple lasers in Laser Powder Bed Fusion (LPBF) additive manufacturing of metals, enhancing both speed and productivity—making it ideal for high-volume projects. Our strategic investment in top-of-the-line LPBF systems ensures unmatched quality, cost-efficiency, and complete traceability in manufacturing.


Why partner with Apex?

Our in-depth knowledge of LPBF hardware and processes isn’t merely academic—it’s forged from years of hands-on experience in pioneering roles within LPBF system OEMs. We’ve been instrumental in advancing technology from its nascent stages to the mature, reliable platform it is today.

Complementing this technical acumen is our robust real-world manufacturing experience, positioning us uniquely to meet even the most complex technical requirements while optimising production costs. Driven by an insatiable appetite for success, we operate around the clock to deliver superior quality within your required timeframes, ensuring you stay ahead in today’s fast-paced manufacturing landscape.

  • Titanium Alloys: Ti6Al4V Gr 23 ELI

    The Ti6Al4V GR23 ELI alloy is a high-purity titanium alloy distinguished by its low levels of interstitial impurities like oxygen, carbon, and nitrogen. Its exceptional strength-to-weight ratio makes it ideal for automotive and aerospace applications requiring lightweight structures. Enhanced ductility and fracture toughness, as well as strong corrosion resistance and biocompatibility, expand its use to surgical and dental applications 

  • Aluminum Alloys: AlSi10Mg

    AlSi10Mg is composed of aluminium, enriched with up to 10% silicon, and traces of magnesium, iron, and other minor elements. Silicon contributes to the alloy’s enhanced hardness and strength by forming Mg2Si precipitates.

    An inherent oxide layer on the alloy’s surface provides substantial corrosion resistance, which can be further heightened through chemical anodizing. It is commonly used for heat exchangers and thermal management applications.

  • Steels: M300 Maraging Steel

    Maraging steels belong to a category of iron-based alloys characterised by a martensitic crystal structure. They derive their unique strength and hardness from the precipitation of intermetallic compounds during ageing, typically at around 500°C (900°F), rather than from carbon content. Nickel serves as the principal alloying element, supplemented by cobalt, molybdenum, and titanium. The alloy known as Maraging steel M300 is alternatively identified as 1.2709.  

  • Steels: 316L Austenitic Stainless Steel

    The 316L alloy is a specialised form of austenitic stainless steel, primarily composed of iron and alloyed with up to 18% chromium, 14% nickel, and 3% molybdenum, among other trace elements. Distinguished as an extra-low carbon variant of the standard 316 alloy, it offers enhanced resistance to sensitisation, which is carbide precipitation at grain boundaries. This feature contributes to the alloy’s commendable weldability and superior resistance to stress rupture and tensile strength at elevated temperatures.  

  • Nickel Super Alloys: IN625

    The IN625 alloy is primarily composed of nickel, enriched with up to 23% chromium and 10% molybdenum, among other subsidiary elements. A key feature of this alloy is the inclusion of niobium, which synergistically interacts with molybdenum to confer high strength and toughness in its annealed state. IN625 finds extensive utility across diverse industrial applications, excelling particularly in environments like seawater where robust corrosion resistance is imperative. IN625 is also resistant to high temperatures and shares similarities with IN718, an alloy valued for its exceptional tensile, creep, and rupture strength properties.  

  • Nickel Super Alloys: IN718

    The IN718 alloy predominantly consists of nickel, constituting up to 55% by mass, and is further alloyed with iron and chromium, each reaching up to 21%, among other trace elements. In718 is distinguished by its high strength, remarkable corrosion resistance, and an operational temperature range extending from -250°C to 650°C (-418°F to 1200°F). Additionally, it possesses age-hardening capabilities. IN718 is highly versatile in industrial applications that demand robust tensile, creep, and rupture strength. It shares application niches with IN625, an alloy favoured for its high-temperature corrosion and oxidation resistance. 

    The alloy’s exceptional weldability and crack resistance also make it a preferred material for additive manufacturing processes.
