BCN3D Epsilon W27 features

Like every other printer in the market, Epsilon W27 too has a set of features that make it stand out.

Independent Dual Extrusion Technology

Primarily targetting to decrease batch production time, the Epsilon W27 3D printer is based on independent dual extrusion technology.

Because of this, the printer can print using four different modes apart from the standard single-mode.

  1. The Duplication Mode enables users of this printer to print identical models at the same time, doubling the rate during batch productions.
  2. The Mirror Mode enabling users to print mirrored designs symmetrically and hence speeding up the iterations.
  3. The Soluble Supports Mode creates intricate structures at the cost of avoiding geometric limitations.
  4. The Multimaterial Mode technique lets one create two different materials and combine their properties.

Printing using these different modes, either increase your overall print speed or lets you print parts and functional prototypes eccentrically.

Both of which sets this printer apart from the other printers available in the market at the same price.

Humidity controlled environment and complete work station

For extending the service life of your 3D printing materials, Epsilon W27 is designed with silica gel that opens up to the dehumidifying environment for absorbing the moisture from the air in the chamber where the 3D printing material is stored.

After the silica gel becomes saturated, as it is associated with the materials, it gets heated up until it releases moisture that is clearing out of the system.

It is because of this process in the printer that the filaments for printing parts and functional prototypes are stored in dry and optimal conditions for their use.

Especially keeping in mind on-demand 3D printing service providers in mind, the printer manufacturer BCN3D has installed a tool drawer that provides every utensil you might need during any time in the 3D printing process especially while post-processing of parts or functional prototypes.

Additionally, there is an extra space for your laptop or tablet that you count on for completing your set of devices for a full work station, by a 3D printer.

Print while in storage and uninterruptible power supply

Epsilon W27 hosts a dehumidifier that has the capacity to fit, either up to eight spools that weighs between 750 grams and one kilogram, or up to four spools that weigh up to 2.5 kilograms.

Loading of this dehumidifier can directly be done in the 3D printer’s humidity-controlled environment, permitting users to print while keeping the materials used for 3D printing in an ideal condition.

Whenever there is an electricity failure, the system provides extra two minutes of additional print time even after the blackout.

This permits users of the printer to return automatically to the home position, and once the power is back, the user will be able to resume printing from their last positions.

Full enclosure and passively heated chamber and Safety

The Epsilon series printers are built on a fully enclosed chamber that keeps the internal chamber’s temperature-controlled, which allows for a smooth 3D printing process.

The print chamber is known to reach 60 degrees Celsius temperature, whereas the heated bed of this printer can reach up to 120 degrees Celsius.

For ensuring that all the parts or functional prototypes manufactured by this printer are safe, the printer comes equipped with HEPA as well as Carbon Filter.

Epsilon W27 has a HEPA filter that protects the working environment from all the potentially harmful particles while printing with industrial materials.

The Carbon filter inside this printer shields our environment from any harmful fumes that are produced while the production of parts or functional prototypes made from industrial 3D printing materials.

Additionally, there is a safety pause feature in Epsilon W27 which stops the printing process every time the door that gives access to the enclosure is opened.

The multilingual five-inch touchscreen on an Aluminum frame

The sturdy aluminum frame for guaranteed strength and durability fixes the printer on the work floor while the 3D printing process is going on and does not let it vibrate.

At the bottom right end of the printer’s body, there are a five inches long multilingual touchscreen interface that lets the user operate as well as monitor the 3D printer.

To add an extra dose of comfortability, the touchscreen is programmed to display information in more than one language.

It guides you through the advanced features of this printer and helps you self-learn it.

Heated bed and hotends

Epsilon W27 is equipped with e3D hotends that are the best in the industry for delivering the smoothest and the most reliable extrusion.

Whereas the heated bed of the printer can withstand temperatures up to 120 degrees Celsius, which are ideal for printing engineering-grade materials and avoiding warping issues while printing.

So, once you have bought this printer you are destined to get parts and functional prototypes that are of high-quality which can be used at the application in various spaces.

Printing with fiber materials such as PAHT, CF 15 as well as PP GF30 is also possible using the Epsilon W27 because the newly designed hotend is compatible to do so.

It can print seamlessly with fiber-filled materials, apart from PLA, PETG, TPU 98A, PVA, ABS, PA, and PP.

BCN3D Cloud

Epsilon W27 is equipped with the latest connectivity features which enable you to easily send your print files whenever you are connected to the network for a hassle-free file transfer.

The BCN3D Cloud platform also allows for automatic upgrading of firmware using it’s over air updates which will ensure that your printer is always up to date.
