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.

Create beautiful, functional carbon fibre parts with no post processing needed. Create strong parts in a matter of hours, at an affordable price point.
The Markforged Onyx One is the most affordable 3D printer Markforged has ever made, but it’s equally as capable as 3D printers that cost ten times more. With the ability to print with Onyx filament - a nylon and chopped carbon fibre mashup, you can 3D print industrial-strength parts and consumer-facing casings and products, with pinpoint accuracy and outstanding dimensional accuracy. And best of all, the Onyx One 3D printer has a roomy 320 mm x 132 mm x 154 mm build volume, with access to cloud Eiger software.
Designed for Engineers
The Onyx One 3D printer has been designed from the ground up to 3D print carbon fibre, which is an incredibly abrasive material. Carbon fibre wears down brass nozzles very quickly, so it can’t be printed consistently with a regular 3D printer. No other 3D printer on the market has been designed with the sole intention to print carbon fibre. Engineers can use their Onyx One 3D printer to create parts that are dependable and robust, for a wide variety of applications, from robotic tooling to consumer electronics.
Crucially, parts printed with Onyx have a perfect matte finish fresh from the print bed, so they can go straight to work, with no post-processing necessary.
Print Products with an Outstanding Finish
The mineral black onyx is well-known for its surface finish, and that’s why Onyx filament has been named as such. It doesn’t actually contain any onyx mineral, but parts that are 3D printed with Onyx filament are flawless, with excellent hardness and stiffness. And, since Onyx is part nylon and part chopped carbon fibre, you get the stiffness and resilience of carbon fibre, and the engineering toughness and wear resistance of nylon. Onyx filament also has excellent dimensional stability, meaning you can 3D print parts that are true to your CAD design, without having to worry about warping or splitting.
As the entry point to the Markforged 3D printer range, the Onyx One offers all engineers a truly fantastic opportunity to step into the wonderful world of 3D printing.
What People Say
“Due to the robustness of the build quality and some fine engineering work, once you’ve worked through the bed levelling process, you can pretty much leave it alone. We’ve not relevelled the machine in our office in about three months since installation”
– Al Dean, Develop3D
“Onyx is strong enough and flexible enough in the Z direction to actually allow for 3D printed springs, both for extension and compression.”
– Alex Crease, Markforged
“Onyx is one of my favourite materials because it combines stronger composite material with the chemical resistivity of nylon”
– J.R.Everett, Dixon Valve
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.
