We are the 3D printing arm of a larger company called Express Group Ltd. Fixing printers since 1988, today we are a Specialist Parts Distributor and Experts in 3D Printing.
We take quality control very seriously, which is why we are audited for ISO9001:2015 certification, this helps ensure we provide great customer service.
3D printers have been in use in the manufacturing industry for more than thirty years, but it is only really in the last ten that the market has opened itself up to other applications on a large scale, such as mould making for investment casting and tooling. Applications are also emerging for the medical and dental fields.
All of which is to say, 3D printing is no longer constrained by manufacturing limitations or design complexity; and as a result, it is seeing incredible growth.

The Zortrax M300 Dual enables you to 3D print more complex models. The dual-extrusion technology simultaneously prints with separate support and base filament, allowing models with overhangs and intricate geometries to be fabricated.
Zortrax calls this LPD Plus dual-extrusion technology. It has the unique ability to print in single or dual extrusion mode. The two nozzle and double hot-end setup is engineered to deliver high performance and reliability, allowing you to run the 3D printer on back-to-back cycles with minimal uptime and consistent results.
The build volume is 265 x 265 x 300 mm (10.4 x 10.4 x 11.8 in) which is big enough to fabricate large parts and replicate a series of smaller parts during one print cycle. The extruder is engineered to deliver fast print speeds at 100 - 300 microns whether you choose single or dual extrusion mode for your parts.
The minimum wall thickness is 400 microns and Z-SUITE 2, the printer’s dedicated slicing application, has a neat feature which highlights the walls too thin to be printed properly to prevent failed prints. Z-SUITE 2 also supports raft-free printing which ensures you can make full use of the glass build platform included in the box.
Speaking of build platforms, the M300 Dual comes with a perforated build platform and glass build platform. These are automatically calibrated thanks to a capacitive displacement sensor to eliminate the need for manual intervention.
The M300 Dual also has advanced filament control with runout detection, and a blackout response system which automatically resumes printing following a power outage. This helps minimise the risk of print failure.
You can print with Zortrax filament - Z-NYLON, Z-PLA, Z-PETG, Z-ULTRAT, Z-GLASS - and the M300 Dual also has third party filament support. This means you are free to use supported third party filaments without voiding your printer warranty.
What People Say
“The two nozzles extrude at alternate times to create the desired printed object and use a water-soluble support material. After printing is complete, the support can easily be rinsed off.”
The best 3D printers fabricate models and parts that are true to design. In other words, models and parts that are a perfect physical representation of the digital model drawn in CAD. To achieve this high degree of dimensional accuracy, printers must produce a very fine edge across the build area. This is how we perceive parts to be high quality or not when we look at them and inspect them.
Of course, multiple variables determine how fine that edge is, and you cannot always rely on the quantitative values manufacturers place on their 3D printers. If we did, every printer on the market would be pinpoint accurate.
When you are shopping for your next printer, consider this: accuracy is the value that determines how close a 3D printed part is to its digital drawing. Precision refers to the repeatability experience of a printer, or how reliable the printing experience is. If you want a consistently good 3D printing experience, you need both.
The two most common 3D printer technologies are FFF and SLA.
The most common technology is fused filament fabrication (FFF), also known as fused deposition modelling (FDM). Both technologies are in fact one in the same.
These 3D printers are the lowest cost. They melt a plastic and extrude it layer-by-layer to build up models from nothing. This process is traditionally best suited to low-cost prototyping, but advancements in technology mean this is no longer the case. There’re more variables that can affect the quality of a print with FFF than SLA, but solutions like an enclosed build chamber and heated build plate reduce this.
SLA (stereolithography) 3D printers use a laser to cure resin (liquid plastic) onto the build platform in desired areas.
Unlike with an FFF 3D printed part, parts printed by an SLA 3D printer need to be post-processed with UV light. This cures the resin, causing it to solidify and reach the mechanical properties required for the application. The method of production is cure, peel, raise, with the laser curing the resin layer by layer; the peel mechanism lifting each new layer off the surface; and the raising action allowing new resin to flow under the build platform.
3D printers are available in all shapes and sizes to suit any project, but there are two common classes: desktop, and large-format.
Desktop printers do exactly what they say on the tin - they fit on a desktop (or most workspaces) and take up around the same footprint as a large LaserJet printer. Large-format printers are four or five times bigger, enabling you to manufacture models and parts like car bumpers and snowboards in one go.
You’ll find the bigger you go, the rarer photopolymer technologies like SLA and DLP (digital light processing) become. This is because they get very expensive as you scale up. Most large-format 3D printers are of the FFF variety because the technology is cheaper and easier to produce on a large, industrial scale.
