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.

For large end-use parts based in onyx complete with continuous strands of fibreglass, carbon fibre, Kevlar or HSHT fibreglass, the Markforged X7 is the printer for when precision and strength is needed. Offering superb strength-to-cost and strength-to-weight ratios as well as high impact resistance, this printer can create parts at a fraction of the cost of machining processes.
Introducing the Markforged X7 - the most powerful composite 3D printer on the market. This 3D printer offers uncompromised strength and precision, with industrial-grade mechatronics and breakthrough technologies which transcend those on the market today.
The X7 can print with Nylon or Onyx as the core build material, and can reinforce parts with Carbon Fiber, Fiberglass, Kevlar, High Strength and High Temperature Fiberglass. Parts that are reinforced with a composite can be as strong as 6061 aluminium.
Print Enormous and Hugely Detailed Parts
The large build volume of the X7 makes it ideal for creating large-scale parts that currently only metal machining processes can handle. With the ability to print parts up to 330mm in width, 250mm in depth and 200mm in height, the X7 offers designers and engineers are real-world alternative to traditional manufacturing techniques. And with a 50-micron print resolution, your parts will come out with a beautiful finish, perfectly capturing the contours, details and textures you design or scan for print.
Stunning Accuracy, Detail and Print Results
The X7 is the first desktop 3D printer of its kind to have in-process laser inspection, a feature which comprises a laser on the print head which scans your parts for dimensional accuracy mid-print, with a 1-micron accuracy. This feature ensures that your parts meet exact tolerances, something which is critical for end-use applications. In addition to this, the Markforged X7 has encoders on the print head for accuracy, silent stepper motors, and an enclosed chamber with a high-precision build plate to guarantee a high degree of part quality.
What People Say
“Our first Markforged printer paid itself off in less than 1.5 months and saved us over 81% versus machining.”
– Bill Hollingsworth, Dixon Valve
“The Markforged [X7] is a unique 3D printer that uses laser scanning to ensure pieces that come off the machine are precisely as ordered.”
– John Biggs, TechCrunch
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.
