Lasers & 3D Printing Gases

Of the many types of lasers, most use either fibre optics or gases to produce the laser beam

Coregas has decades of experience in supplying laser gases and supply systems, so expanding the range to fulfil requirements for 3D printing was a natural extension.

3D printing, also known as additive manufacturing, creates a three-dimensional object by adding successive layers. It is commonly used for rapid prototyping and production of metal parts. Even NASA has turned to 3D printing components for some of its systems.

Gases for lasers and 3D printing

Gas lasers, where an electric current is discharged through a gas to produce light, have been used for a range of purposes with many gases.

Helium and helium-neon lasers

Some of the most common gas lasers use helium or a helium-neon (HeNe) mixture to produce visible red light. The popularity of these lasers stems in part from their ability to operate at a range of wavelengths. They have multiple commercial and industrial uses, from producing holograms and scanning in older models of barcode scanner, to precise tool alignment and laboratory laser demonstrations.

Carbon dioxide (CO2) lasers

Powerful lasers emitting energy in the far-infrared, CO2 lasers are ideal for welding and cutting hard materials. They are also suitable for a range of precision medical applications including laser surgery and skin resurfacing, even replacing a scalpel in certain instances.

Fibre lasers

The most popular power source in industrial applications such as laser welding and cutting.

Nitrogen lasers

Nitrogen lasers operate in the ultraviolet range and have uses ranging from measurement of air pollution to assisting in the operation of other lasers.

Less common lasers

The Coregas range extends to less common laser and 3D printing gases too. For instance, reactive gases such as chlorine and fluorine, mixed with inert gases such as argon, krypton or xenon, are available for use with excimer lasers. Gases mixtures for Transversely Excited Atmospheric lasers (or TEA lasers) and chemical lasers are also available. For more information about our full range or for specialised mixtures, contact our friendly customer services team.

Argon, nitrogen and mixtures for 3D printing

Additive manufacturing demands high tolerances, which are more easily achieved in the inert atmosphere provided by gases such as high purity argon, nitrogen and related mixtures. The Coregas team has supplied 3D printing since its inception, so you can be confident that it can provide the expertise to assist you in optimising your process.

Industries using lasers and 3D printing gas

Coregas supplies high-purity laser gases to a diverse range of industries across Australia and New Zealand. These gases play a critical role in both laser systems and additive manufacturing environments, where consistent gas quality and system compatibility are essential.

  • Manufacturing and fabrication — Gases such as nitrogen and oxygen are used for laser cutting in high-volume production.
  • Automotive and aerospace — Additive manufacturing with inert gases enables rapid prototyping and the production of lightweight metal components with high structural integrity.
  • Medical and healthcare — Laser applications in this sector include precise cutting, surgical tools and advanced skin treatment systems. Gases used must meet strict purity requirements.
  • Electronics and semiconductors — Nitrogen and helium are used in laser systems and cleanroom environments where ultra-low contamination is essential.
  • Research and education — Laboratories and research institutions use laser gases for spectroscopy, holography, alignment tools and experimental setups.

Choose the right gas cylinder size for your application

To meet a range of application requirements, Coregas offers a complete selection of gas cylinder sizes, from portable cylinders for laboratory and light industrial use to large-volume packs and cryogenic storage.

For laser cutting, welding, and 3D printing, the right cylinder size ensures stable performance, reduces cylinder changeover time and keeps operations running efficiently. We stock:

  • Portable and mid-size cylinders for helium, nitrogen, CO2 and custom blends
  • Multi-cylinder packs for continuous gas flow during large-scale production
  • Bulk and cryogenic vessels for facilities requiring high-volume storage

If you're unsure what size best suits your setup, our team can recommend a solution based on your usage, flow rate, delivery method and frequency of changeover.

Certificate of Conformance available for laser cutting, laser welding, and 3D printing gases

For added assurance and traceability, every Coregas laser gas product can be supplied with a Certificate of Conformance (COC). The COC confirms:

  • The gas type and product name
  • The composition and cylinder fill
  • That the product meets Coregas’ quality standards

COCs are available for all standard sizes and are easily downloadable from the relevant product page by scrolling to the specification table. This documentation is particularly valuable for regulated industries and businesses that require consistent quality verification across supply cycles.

Flexible delivery and collection options for laser gases

Coregas offers convenient and reliable delivery and collection services for our full range of laser gases, helping you stay stocked and operational without delays. Whether you're a large-scale manufacturer or a smaller specialist workshop, we provide flexible supply solutions to suit your location and production schedule.

  • Next day delivery is available for stocked gases when ordered before 2:30 pm. This ensures reliable turnaround for regular production cycles and helps reduce the risk of downtime caused by gas shortages.
  • Click and collect from Coregas branches located nationwide. Most branches operate Monday to Friday from 8:30 am to 4:30 pm, though local hours may vary. Our branch staff are trained to assist with order collection and product advice, ensuring a smooth pickup experience.
  • Depot and distributor collection is available for customers in regional and remote areas. You can order directly with Coregas or through accredited third-party partners who carry our products. This extended network makes it easier to access laser gases wherever you're based.

Simplify gas management with the Coregas app

The Coregas Mobile App makes ordering and managing your laser gas supply more efficient. Designed for convenience, the app is ideal for technicians, production managers and businesses managing multiple sites or high gas usage.

With the app, you can:
