Industrial 3D Printing: Transforming manufacturing

 3D Printing is a manufacturing methodology that encompasses a range of processes and applications, with a common theme of building parts up, usually layer-upon-layer. This additive approach ultimately enables manufacturers to eliminate the need for tooling. This simple but powerful differentiator brings with it a number of significant advantages, including superior geometric freedom, giving designers much more capability, and a substantial reduction in lead time for products.

 In addition 3D Printing provides the facility to tailor unique products to consumers, enable de-centralised manufacturing and shrink spare part storage – not to mention the time, environmental and cost benefits delivered with these. The opportunities are endless with 3D Printing, and with market growth rates of over 30% per annum, it is providing many global industries with a completely new approach to their manufacturing processes – 3D Printing is no longer just delivering its benefits for rapid prototyping/tooling, but delivering as an industrial process for part production.

 As 3D Printing moves towards producing functional, end-use parts, manufacturers are ensuring that they can deliver reliable, repeatable systems for producing at high volume.

Fast and scalable

Slow 3D Printers are a barrier to high productivity. However, inkjet printheads are capable of accurately ejecting droplets of fluids thousands of times per second, whilst the capability of using multiple printheads on a single systems enables 3D Printing to scale and deliver volume production.

A proven, robust technology

The digital inkjet market has been established for decades, and the technology has been used across a wide range of applications, such as for printing graphics, ceramic tiles, packaging and labels. Digital inkjet has proven itself in a number of harsh environments, where high volume is critical, and will therefore will be a cornerstone in the growing 3D market.

Economical

Systems and components continue to be prohibitively expensive to potential adopters. In comparison to systems that use lasers or similar, inkjet printheads have a significantly lower purchase price and prove much more cost-effective over the lifetime of machines.

Enabled by inkjet technology, mass production 3D Printing is now a reality

High Speed Sintering works by depositing a fine layer of powder onto the surface of a powder bed, an inkjet printhead then selectively prints an infrared (IR) absorbing fluid directly on to the powder surface. The entire surface is irradiated with IR energy causing only the printed areas to melt/sinter, the unprinted areas remain as powder. This process is repeated layer by layer until the build is complete, un-sintered powder is then removed to reveal the final part(s).

The most common material jetting process works by depositing droplets of material onto a build bed platform, which are then cured using a UV light source. This repeats layer-by-layer, until you are left with the finished 3D object. We call this Print & Cure (P&C).

 Desirables in the P&C sector include parts with superior mechanical properties, which requires viscous fluids, and parts with richer colours, which needs fluids with high pigment loading. These are traditionally challenging aspects for inkjet, but Xaar’s technology allows for this to be achieved.

  • Xaar’s High Laydown (HL) Technology facilitates the printing of highly viscous fluids, whilst also enabling outstanding rates of productivity
  • Xaar’s TF Technology ensures a continuous ink flow at a high rate directly past the back of the nozzle, preventing sedimentation in highly loaded inks, as well as carrying away air bubbles and keeping nozzles primed.

Larger bed sizes are key for achieving high rates of productivity, with the need to retain the ability to produce fine-featured, highly detailed parts.

  • Xaar’s technology is fully scalable, which enables the integration of multiple printheads for single pass printing over large build bed areas
  • Greyscale operation allows the jetting of variable drop volumes, whilst the capability to swap between high laydown and standard printing delivers high throughput or high resolution jetting.



The binder jetting process works by depositing an agent onto a powder substrate, which binds the powder particles together. Another layer of powder is applied, and the process repeats until the 3D object is complete. Both polymer and metal powders are widely used, and in the case of the former, no support structures are generally required. We call this as Print & Bind (P&B).

Challenging fluids that can damage less robust printheads are commonly used in P&B to achieve suitable part properties, with aqueous, particle-filled and high pH fluids common.

  • Xaar’s robust printheads are compatible with a broad range of ink types, with the launch of printheads suitable for aqueous and high pH fluids further expanding this capability, and meaning minimal compromise on fluid choice for an OEM
  • Xaar’s TF Technology ensures a continuous ink flow at a high rate directly past the back of the nozzle, removing air bubbles and preventing sedimentation in highly loaded inks.

Larger parts are a common requirement for the industrial end-users of print and bind, with productivity also being essential. Xaar’s technology is fully scalable, which enables the integration of multiple printheads for single pass printing over large build bed areas.

Why Xaar Technology?

Xaar is the world’s leading independent manufacturer of piezo-based drop-on-demand inkjet technologies, and our printheads are trusted in industrial markets around the globe – where they are proven to work in the most challenging manufacturing environments, with minimal downtime and maintenance requirements.

Xaar offers:

  • An extensive printhead portfolio, ensuring a suitable fit for a wide range of applications
  • Easy to integrate system components, including ink supply systems and drive electronics, reducing the time-to-market for OEMs
  • An open business model - meaning less restriction on ink choice, and moving away from the barriers to volume and competiveness associated with closed supply chains.

Inkjet is an enabling technology with its ability to integrate with a range of fluids and processes. Whilst Xaar is constantly exploring and offering its expertise across this range of applications to help drive the market forward, two key processes have established themselves as front-runners in inkjet 3D printing which are Material jetting and Binder jetting.
