The BCN3D Sigma R19 is a professional dual extruder 3D printer is BCN3D’s latest version of it’s acclaimed Sigma series. The Sigma now features e3D optimised hotends, hardened steel BondTech drive gears in the extruder, a filament run out sensor and improved z-axis stability.

NOTE: There are currently quite long lead times on these printers – Approx Early July

The BCN3D Sigma is built with an innovative independent dual extruder system so you can print with two different materials, or in two different colours, whilst maintaining a high quality surface finish. The idle printhead in this dual extruder 3D printer remains parked to stop it from dripping molten filament onto your 3D print.

bcn3d sigma dual extruder 3d printer allows you to 3D print complex models using soluble support material

Buying a dual extrusion 3d printer is not just about printing attractive two tone prints, where it comes into its own is when you combine two different materials in one print. This is especially true when you make use of a soluble support filament like HIPS (for ABS) or a water soluble PVA filament. If you use a soluble support filament as infill this allows you to make very complex parts that would not be possible with a single extruder 3D printer. A dual extruder 3D printer therefore opens up the possibility for 3D printing functional parts.

Avoid geometric limitations and print the most challenging parts thanks to soluble supports.

Sigma features

The Sigma R19 sees a number of hardware updates to improve performance and capabilities. The Sigma employs the IDEX replaceable hotend system. The new hotends have been optimised by e3D and are powered by Bondtech extruders. BCN3D partnered with e3D to utilise their know how in the design and development of high performance hotends to produce the range of sigma e3D hotends. The new e3D hotends are also backward compatible with the previous version of the Sigma. With the Sigma full metal hotends you can print any material you need to fit your requirements, from common PLA to the most advanced technical plastics like Nylon or PC, independent of the filament manufacturer.

IDEX swappable Hotends

The IDEX system uses a series of swappable hotends with different nozzle diameters and nozzle characteristics. This means you can select the right hotend for the job, saving both time and money, making your 3D printing workflow more efficient. For example you can print your perimeters with a 0.3mm hotend and the infill with a 0.8mm hotend, or, print your model with 0.8mm and detailed PVA supports with 0.4mm. Print up to three times faster without giving up quality: finer outlines and coarser infills.

BCN3D Sigma IDEX hotends come in:

  • 0.3mm

  • 0.4mm

  • 0.5mm - Hardened Stainless Steel, ideal for carbon fibre filament like ColorFabb XT CF-20

  • 0.6mm

  • 0.8mm

  • 1.0mm

BCN3D hotends are available as either the Idex Hotend Family Pack or buy your BCNozzle Hotend separately. Or follow the link for a full listing of our BCN3D 3D printer products.

Multiple printing modes for improved work flow

The sigma software also allows for Mirror and duplication mode printing for faster production of multiple versions of the same model or printing symmetrical sides of a composite model, left and right versions.

Improved extruder performance

The Extruder drive system features BondTech dual drive technology to give greater control and superior performance of the extrusion process. The extruder is made with a aluminum CNC machined body and hardened steel drive gears powered by Bondtech. It provides an incredible grip thanks to its high-tech dual drive gears that have proved to be the best feeding extrusion system, getting rid of grinding issues, no matter the filament used.

The Sigma also features a filament run out sensor to helping you manage your printing.

The Sigma has a top grade build quality. The z-axis stage is now built with a CNC machined aluminum block to improve z-axis stability. The new z-axis stage moves the platform smoother, reducing vibrations and so improving z-axis extrusion consistency. The Sigma also boasts a cooling system that gives high performance whilst drastically reducing the operating sound.

With the BCN3D Sigma full colour touchscreen you get an attractive and intuitive interface that is fully equipped with advanced features that guides the user step by step.

UK Shipping

  1. Free UK Mainland Shipping on orders over £150 (incl. VAT); Free Highlands & Channel Islands on orders over £240 (incl. VAT).
  2. Free UK shipping on 3D printer filament samples.
  3. £4.80 (incl. VAT) flat rate for all UK Mainland orders under £150 (incl. VAT); Flat rate of £15.00 (incl. VAT) on Highlands & Channel Islands on orders below £240 (incl. VAT).

Orders over 2kg in weight are shipped via DHL Express orders under 2kg are shipped via Royal Mail 48hrs Tracked.

The advantage of flat rate Postage and Packaging to our customers are that if you order 1, 2, 3, 4 or 5 spools of filament the price is the same.

p.s. Were sorry about the Highland & Islands shipping costs, it’s a reflection on the increased shipping charges we have to pay.

International Shipping

We do ship internationally but ask if you can contact us to arrange an order as shipping costs can vary greatly depending upon destination and weight. Please see or International orders page for more information.

You can return your goods to iDig3Dprinting for any reason within 14 business days following receipt at your delivery address as long as they are in a re-saleable condition.

Filaments & resins cannot be returned once opened as once exposed to air these items perish.

Downloadable goods and 3D print samples cannot be returned and no refund will be issued.

Shipping costs of returned items are paid by the customer

A full refund will be issued for unopened items that are returned in their original packaging that are in a “as new” re-saleable condition minus additional costs that are incurred by iDig3Dprinting like payment processing fees, custom duties or charges.

We are afraid we cannot issue refunds for products that have been defaced, altered, used, or damaged in any way. All requests for refunds are subject to inspection by iDig3DPrinting of the returned item. We are not a charity or a lending library.

Refunds and returns for faulty items works a bit differently. Faulty goods can be accepted for return upto 60 days from receipt of the goods (However we prefer to offer diagnostics and repair solutions prior to an actual return, its better for the environment). After this time you will need to contact the Manufacturer. A repair or replacement will be issued for faulty goods once they have passed inspection and been found by iDig3Dprinting to be faulty.

This is a brief account of our returns policy. For the full terms please see our Terms and conditions page. Content on the Terms and Conditions page supersedes this content.

How to raise a return request

  • email idig3dprinting at support@idig3dprinting.co.uk and we will issue a Return Authorization Number (RAN).
