BCN3D Technologies, a prominent manufacturer based in Barcelona, Spain, has significantly advanced the landscape of fused filament fabrication (FFF) 3D printing. The company’s core innovation, Independent Dual Extrusion (IDEX) technology, underpins its range of professional and industrial-grade printers, offering enhanced productivity and material versatility for demanding applications.
Since its inception as a division of CIM-UPC in 2011, BCN3D has focused on democratizing additive manufacturing through open-source principles and robust hardware development. Their commitment to providing high-quality tools for professionals and industrial users has positioned them as a leader in the global 3D printing market.
Independent Dual Extrusion (IDEX) Technology
BCN3D’s signature IDEX system distinguishes its printers by allowing two print heads to operate completely independently on the X and E axes, while sharing the Y and Z axes. This unique architecture prevents cross-contamination between materials and enables advanced printing modes not possible with conventional dual extrusion systems where both extruders are on the same tool head.
The independent movement of each extruder ensures that the inactive print head remains parked, eliminating the risk of dripping molten plastic onto the printed part. This ‘clean’ dual extrusion is critical for achieving high-quality multi-material or multi-color prints, especially when using soluble support structures.

| Nozzle Diameters | 0.4, 0.6, 0.8, 1.0 mm (Hotend X 0.6mm) | 0.4, 0.6, 0.8, 1.0 mm (Hotend X 0.6mm) |
| Layer Height | 0.05 – 0.5 mm | 0.05 – 0.5 mm |

IDEX technology unlocks specialized printing modes that significantly boost throughput for batch production and rapid prototyping. Duplication mode allows the printer to produce two identical parts simultaneously, effectively doubling the production capacity within the same timeframe.
Mirror mode further enhances efficiency by printing a symmetrical version of a part concurrently with the original. This is particularly useful for manufacturing ‘left’ and ‘right’ hand components from a single STL file, streamlining design iterations and reducing overall print time by 50%.
The BCN3D Epsilon Series: Industrial-Grade Performance
The BCN3D Epsilon series, including the W50 and W27 models, represents the company’s offering for industrial applications, combining large build volumes with robust features. These printers are engineered for demanding environments, featuring a full enclosure and a passively heated chamber capable of reaching up to 60°C.
Equipped with Bondtech™ high-tech dual drive gears and optimized E3D™ hotends, the Epsilon printers ensure reliable and smooth filament extrusion. They also incorporate advanced safety features like HEPA and carbon filters to manage particle and fume emissions, alongside a ‘Safety Pause’ that halts printing if the enclosure door opens.
The Epsilon series offers a heated bed that can reach 120°C, crucial for printing engineering-grade materials and minimizing warping. An integrated autocalibration system adjusts the printing surface height and XY offset between nozzles in under six minutes, ensuring consistent first-layer adhesion.
Connectivity is a key aspect, with features like Wi-Fi, Ethernet, and compatibility with the BCN3D Cloud service for remote file management and over-the-air (OTA) firmware updates. The optional Smart Cabinet further enhances the Epsilon ecosystem by controlling filament humidity and providing an uninterruptible power supply.
High-Grade Engineering Filaments and Open Material System
BCN3D printers are designed to work with a broad spectrum of engineering-grade filaments, including ABS, PP, PET-G, PA, and various fiber-filled composites like PP GF30 and PAHT CF15. These materials are crucial for producing functional prototypes, tooling, jigs, and end-use parts with specific mechanical and thermal properties.
The company maintains an ‘Open Filament Network’ (OFN), allowing users to confidently employ third-party materials alongside BCN3D’s own portfolio. This open approach, supported by collaborations with chemical companies like BASF and Mitsubishi Chemical, ensures users have access to optimized printing profiles and a wide selection of specialized filaments.
For FDM 3D printing, typical dimensional tolerances range from ±0.15% (lower limit ±0.2 mm) for industrial machines to ±0.5% (lower limit ±0.5 mm) for prototyping. For well-calibrated machines, a general tolerance of ±0.3 mm on features smaller than 100 mm is expected, with larger dimensions seeing approximately ±0.3% of the nominal size.
Recommended print speeds for materials like PET-G on enclosed BCN3D models are around 30 mm/s, while open models can reach 45 mm/s. For PA, speeds typically range from 30-60 mm/s. These parameters are often optimized within BCN3D Stratos, the company’s slicing software, to balance print quality and speed.
Barcelona Additive Innovation
BCN3D’s roots are deeply embedded in Barcelona’s vibrant additive manufacturing ecosystem, originating as a spin-off from the Polytechnic University of Catalonia (CIM-UPC). This connection to a leading technological center has fostered a culture of continuous research and development in FFF technology.
The company’s commitment to innovation extends beyond hardware, encompassing software solutions like BCN3D Stratos and the BCN3D Cloud, along with strategic acquisitions such as AstroPrint for sophisticated cloud solutions. This integrated approach aims to provide a comprehensive and seamless 3D printing experience for industrial users.
Barcelona itself is a recognized hub for 3D printing and digital manufacturing, attracting significant investment and housing advanced R&D facilities. This environment provides BCN3D with access to talent, collaborative opportunities, and a strong foundation for developing next-generation additive manufacturing technologies.
