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 the manufacturer of the #1 Most Used Desktop Printer 2018, there's a new printer around – the Formlabs Form 3.
The Form 3 is a Low Force Stereolithography (LFS) printer. This new technology balances speed and detail to give intricate prints quickly. Adaptive layer height allows for you to print the non-detailed parts of your model more quickly (at a lower resolution), whilst retaining the high resolution required for the intricate areas.
LFS gently flexes the tank to release the newly cured layer. This technique allows for much less force on the printed layer and no lateral peel force is necessary. Because of this, the supports are very light touch – a simple twist should remove them completely from the model.
The Form 3 brings in the ability to set off a print remotely. Orientate and support the model as required in PreForm, Formlabs’ printing software, and send it to the printer from wherever you are. Design and prepare your model at home in an evening and come into the office to have it printed in the morning.
For those of you already familiar with the Form 2, you’ll be pleased to know that your cartridges, build plates, finishing kits, Form Wash and Form Cure are all compatible with the Form 3. The only things that are not cross compatible are the tanks due to the different peel mechanisms.
There are ten Formlabs resins that can be used with the Form 3 immediately, these are: Grey, Black, White, Clear, Draft, Tough, High Temp V2, Durable, Castable Wax and Dental Model. Others are in compatibility testing and certification and should be released shortly. You can also use third-party resins with the Form 3 by using Open Mode.

If you have any questions about the Form 3, or you would like to discuss anything further, please get in contact with our team on 01765 694007, or email firstname.lastname@example.org
Here are some of the common questions we get for Form 3 Extended Complete Package, if you have any more questions, please don't hesitate to email email@example.com or phone 01765 540 115.
Can I use Form 2 consumables with the Form 3?
Cartridges, build platforms, finishing kits, Form Wash and Form Cure are compatible between the Form 2 and Form 3.
Tanks are not compatible between the Form 2 and Form 3.
Can I use the Form 3 for biocompatible printing?
Biocompatibility is certified for an entire workflow. This is in process for the Form 3 but has not yet been finalised, so at the moment the Form 3 is not recommended if biocompatibility is required.
How is the Form 3 different to the Form 2?
They use different technologies. The Form 2 is a stereolithography (SLA) printer, the Form 3 is a Low Force Stereolithography (LFS) printer. For a deeper comparison please see our downloads section.
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.
