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.
Markforged makes industry-leading 3D printers for applications in engineering, manufacturing, product design and functional prototyping. Print metal, carbon fibre, high-temp fibreglass, fibreglass, Kevlar and more. Print parts, tools, and fixtures stronger than metal, or even in metal. The possibilities are endless, and the 3D printers are tried, tested and proven in industry. Quality is the Markforged difference. This is a brand you can rely on to deliver consistency every time.
Please fill out the details below and we will get back to you as soon as possible.
The Bowden Tube is a critical component of the Markforged desktop printers. This component feeds onyx (or nylon if using) filament through to the extruder, where it is extruded layer-by-layer by the printer’s dedicated FFF nozzle.
The product you are looking at here today is an official Markforged replacement plastic Bowden tube. This tube will replace your older plastic Bowden tube which may have become damaged over time. For example, Bowden tubes can become clogged with material through extensive use, or they can be stretched or kinked accidentally. If your Bowden tube is clogged or it has become damaged, then you should replace it. If you do not, then the printer's extruder may not be supplied with the filament it needs, which may ruin prints.
The good news with regards to this is that a replacement Bowden tube is an inexpensive piece of equipment. And if you clean any filament left in the tube and you look after it, your replacement tube should last you through over a hundred print cycles. It is also important however to maintain your fibre Bowden tube. This should be replaced alongside your plastic Bowden tube, if it too has become damaged.
Many 3D printers lay claim to being ‘industrial-grade’ but when you delve into their material list, rarely do you find anything more durable than nylon.
That’s where Markforged 3D printers differ. In the case of the Desktop and Industrial series 3D printers, these use nylon or Onyx as the base material (Onyx is a proprietary filament made by Markforged, it’s part nylon, part chopped carbon fibre). You can then reinforce prints with continuous strands of a stronger composite - carbon fibre, fibreglass, or Kevlar - to create truly industrial-grade prototypes and end-use parts.
For example, parts printed in carbon fibre are stronger than 6061-T6 aluminium. The Desktop series includes the Mark Two, Onyx One and Onyx Pro, and the Industrial series the X7, X5, and X3. There’s a printer for every application.
Then there’s the Metal X, Markforged’s greatest machine yet. This 3D printer utilises a process called ADAM (Atomic Diffusion Additive Manufacturing) to print parts in powdered metal surrounded by a plastic support. The parts are then sintered in a furnace externally to become solid. This enables you to manufacture metal parts with geometries and details that would be impossible with subtractive manufacturing processes.
