In this article, we are going to share information about various characteristics of this printer including features, specifications, as well as print quality, setup, and a lot more.


Below mentioned are those features of the printer which are worth appreciating.

Two types of filters, as well as safety pause

Epsilon W50 printer comes with HEPA as well as a carbon filter. The function of the HEPA filter is to ensure that your working environment does not interact with any kind of harmful particles when you are printing with industrial materials.

Whereas the function of a Carbon filter is to shield your printer from any dangerous fumes that are produced when the printing material burns.

Additionally, the printer manufacturer has kept in mind the uncertainty that involves door locks. Epsilon W50 comes with a glass door lock unlocking which one is granted access to the inner print chamber.

Whenever this door gets opened, the printing stops automatically to ensure that there is no interaction between the outer and the inner atmosphere.

Heated bed and filament run-out sensors

Pertaining to the requirements of letting one print with more than one filament, BCN3D has kept their heated bed capable of withstanding 120 degrees Celsius of temperature.

This allows Epsilon W50 to print with 3D filament made from materials PLA, PETG, TPU 98A, PVA, ABS, PA, and PP.

When the filament of the printer is finished, there is a sensor that detects the finished filament and pauses the printing process until it is reloaded again.

This filament run-out sensor saves your job and from print failure.

Bondtech Extruders and touchscreen interface

The extruders inside this 3D printer has high-tech dual drive gears by the company named Bondtech.

The company is very well known in the field of the 3D printing industry for offering more control, sharper details, as well as superior performance for any type of 3D printing filament.

The multilingual intuitive touch interface is present at the bottom right part of the body of the printer.

This touchscreen interface can guide you to the printer’s advanced features. The five-inch long touchscreen interface is available in many supported languages.

e3D Hotends and Aluminum frame

To deliver one of the smoothest extrusions ever, BCN3D has equipped the Epsilon W50 with e3D hotends, which is the smoothest and reliable extrusion maker in the 3D printing market.

To ensure that the printer does not vibrate while 3D printing a part or functional prototype, the manufacturer of this printer has made its body from Aluminum.

So, a sturdy printer frame is a guaranteed present for giving you strength as well as durability on your work floor.

Independent Dual Extrusion System

To expedite the printing process, especially during batch production, BCN3D has made Epsilon W50 comprising of an independent dual extrusion system that can print with four other modes than a single mode of 3D printing a part or functional prototype.

  1. The multi-material mode makes printing two different materials and combining their properties possible.
  2. The soluble supports mode for creating intricate structures for avoiding geometric limitations.
  3. There is a Mirror Mode for enabling the printing of two mirrored designs symmetrically and speeding up the iteration time.
  4. The Duplicate Mode enables printer users to print two identical models simultaneously which means that instead of a single part or functional prototype, you will have two parts or functional prototypes in a fixed set of time, doubling the production capacity.

Uninterruptible Power Supply and printing while in storage

This is a noteworthy feature that you would not get to see in the printers fall in the same price range.

BCN3D Epsilon W50 allows its users to print even after the electricity failure happens, for two extra minutes.

And after the power is back, you will be given the function to resume your print from its last position, so enabling you an uninterrupted power supply.

There is a dehumidifier that can fit up to either up to eight small spools that weigh anywhere between 750 grams or one kilogram, or four big spools weighing up to 2.5 kilograms.

All of these can be directly loaded into the humidity controlled environment of the printer, so all your material needed for 3D printing parts or functional prototypes are in an ideal condition.

Humidity-controlled environment and easy storage and transportation

The designers of Epsilon W50 have kept silica gel inside the printer’s storage space for ensuring the humidifying atmosphere is developed inside the printer.

The silica gel absorbs moisture from the storage chamber, keeping all the 3D printing material safe and secured.

After the silica gel becomes saturated, it is isolated from the materials and gets heated up until it releases the complete moisture and thereby clearing it out of the system.

A result of all this is that the filament material in the storage chamber is dry and optimal for use.

This printer can also be bought with Smart Cabinet which is a transportable structure that allows the moving of this printer across various facilities.

Having such a smart cabinet would allow you to keep your workspace organized as well as clean all the time, by permitting you for surplus space for keeping materials as well as tools.

Passively designed print chamber as well as printing with fiber-filled filaments

The print chamber of this printer is fully enclosed which enables users to undergo a constant temperature 3D printing process.

Additionally, the printer’s heated bed is known to withstand temperatures up to 120 degrees Celsius, whereas the print chamber can reach up to 60 degrees Celsius.

This allows the users of this printer to print with such filaments, whose melting temperature is a lot higher than others.

Using Epsilon W50 one can also print with fiber-filled materials such as PAFT CF15, as well as PPGF 30.

All thanks to the newly designed hotend inside the printer that can sustain an even higher temperature than most other printers in the same price range.

Print Type/Cost

FFF 3D printing technology prints parts or functional prototypes layer by layer.

The printing happens after every 3D printing material reaches its glass transition temperature in the extrusion and then starts melting on the heated bed according to the design file.

And layer by layer the printing continues until the final part or functional prototype is made.

The printing cost of a part or functional prototype using this method is lower than that of any other technology.

But it depends on the type of part you are building, the amount of infill needed in that part as well as its layer resolution.

Print Quality
