BCN3D Sigma D25: A Deep Dive into This Professional 3D Printer

The BCN3D Sigma D25 is a name synonymous with reliable dual extrusion printing in the professional desktop 3D printer market. Boasting Independent Dual Extrusion (IDEX) technology and a well-established ecosystem, it’s designed for users demanding precision, versatility, and consistent results. Let’s break down what makes this printer a standout choice.

Detailed Specifications:

• Printing Technology: Fused Filament Fabrication (FFF) / Fused Deposition Modeling (FDM)
• Build Volume: 420 x 300 x 200 mm (16.5 x 11.8 x 7.9 inches) – A generous build volume for medium to large-sized projects.
• Print Head: Independent Dual Extrusion (IDEX) – Allowing for simultaneous printing in mirror mode, duplication mode, and support material printing.
• Nozzle Diameter: Range of E3D nozzles available (0.3, 0.4, 0.5, 0.6, 0.8 mm) – Provides flexibility for varying levels of detail and print speed.
• Layer Resolution: 50 to 300 microns (0.05 – 0.3 mm) – Offers a good balance between surface finish and printing time.
• Filament Diameter: 2.85 mm – A standard size, ensuring compatibility with a wide range of materials.
• Supported Materials: PLA, ABS, PETG, TPU, PVA, Nylon, ASA, PP, PC, and composites (with appropriate hotend configuration) – Highly versatile material support.
• Heated Bed: Yes – Enables printing with materials prone to warping.
• Maximum Nozzle Temperature: 300°C – Allows for printing high-temperature materials.
• Maximum Bed Temperature: 80°C – Sufficient for most common materials.
• Connectivity: Wi-Fi, Ethernet, USB
• Display: 5-inch full-color touchscreen – Intuitive interface for controlling the printer.
• Software: BCN3D Cura (based on Ultimaker Cura)
• Frame: Enclosed – Provides a stable printing environment and helps control temperature.
• Power Supply: Internal
• Dimensions: 674 x 554 x 680 mm (26.5 x 21.8 x 26.8 inches)
• Weight: 22 kg (48.5 lbs)

Usage Tips for Optimal Results:

• Leveling is Key: Precise bed leveling is critical, especially for dual extrusion. The Sigma D25 features a semi-automatic leveling system, but manual fine-tuning might be necessary. Don’t skip this step!
• Material Profiles are Your Friend: BCN3D Cura comes pre-loaded with optimized profiles for various materials. Start with these profiles and fine-tune them as needed based on your specific filament brand and desired results.
• Dry Filament is Crucial: Hygroscopic materials like Nylon and PVA absorb moisture from the air, leading to printing issues. Store your filaments in airtight containers with desiccant and consider using a filament dryer before printing.
• Take Advantage of IDEX: Explore the possibilities of IDEX. Print complex parts with soluble support materials (PVA) for intricate geometries. Use mirror and duplication modes to accelerate production of identical parts.
• Experiment with Nozzle Combinations: Don’t be afraid to experiment with different nozzle sizes. Using a larger nozzle for infill and a smaller nozzle for perimeters can optimize printing time and surface finish.
• Proper Ventilation: While the D25 is enclosed, ensure proper ventilation when printing materials like ABS that can emit fumes.
• Regular Maintenance: Keep the printer clean and well-lubricated. Regularly clean the nozzles, lubricate the lead screws, and check for any loose connections.

Scoring Breakdown (Out of 10):

• Print Quality: 9 - Excellent detail and surface finish, particularly with calibrated profiles.
• Build Volume: 8 - A good size for most projects, but larger printers exist.
• Printing Speed: 7 - Average speed, prioritizing quality over outright speed.
• Material Compatibility: 9 - Wide range of supported materials, requiring some hotend adjustments for specialized filaments.
• Bed Adhesion & Leveling: 8 - Semi-automatic leveling is helpful, but requires occasional manual adjustments. Bed adhesion is generally good.
• Reliability: 9 - Known for its reliability and consistent performance when properly maintained.
• Ease of Use: 7 - The touchscreen interface is intuitive, but dual extrusion requires some learning.
• Firmware and Software: 8 - BCN3D Cura is powerful and well-integrated, but can feel overwhelming for beginners.
• Connectivity Options: 9 - Offers a comprehensive range of connectivity options.
• Build Quality & Durability: 9 - Robust construction and high-quality components.
• Noise Level: 7 - Moderate noise level, quieter than some other printers.
• Maintenance Requirements: 7 - Requires regular cleaning and lubrication, but not excessively demanding.
• Customer Support: 8 - BCN3D offers responsive customer support through various channels.
• Upgradeability: 7 - Limited upgrade options beyond nozzles and filaments.
• Price to Performance Ratio: 8 - Delivers excellent performance and reliability for its price point.

Average Score: 8.06/10

Conclusion:

The BCN3D Sigma D25 is a powerful and versatile 3D printer that delivers consistent and high-quality results. Its IDEX system opens up a range of possibilities for complex prints and efficient production. While it requires some initial setup and learning, the D25 is a worthy investment for professionals and serious hobbyists seeking a reliable and feature-rich 3D printing solution.
