On-demand webinar: Three ways in which the Smart Cabinet boosts your workflow

Performance

Supported by our smart drying technology, the humidity-controlled environment has been designed to extend the service life of your materials, protecting the filament and reducing print failure due to moisture, significantly improving your prints’ quality.

The mechanical properties of the 3D printed part are strongly dependent on how well the filament is stored

Our Smart Drying Technology

Within our humidity-controlled environment, an automatic drying cycle pushes the air through a compartment filled with alumina, a material that absorbs the moisture.

The desaturated air is pushed back towards the material compartment, free of any moisture that could damage your filaments. This cycle reduces significantly the environment’s relative humidity.

This technology effectively keeps the filament dry, ensuring that the materials maintain their mechanical properties throughout the whole 3D printing process.

BCN3D Spool Cartridge

The new BCN3D Spool Cartridges have been designed to give you greater control during the process of loading and unloading filaments, while significantly accelerating both workflows.

BCN3D Spool Cartridge

The new BCN3D Spool Cartridges have been designed to give you greater control during the process of loading and unloading filaments, while significantly accelerating both workflows.The magnets in their cover and the main body allow for easier loading of spools, as well as to quickly snap the cartridge in the loading or parking area of the Smart Cabinet. This system also prevents filament tangling: when unloading your material, the extra slack due to the long distance between the extruders and print heads is kept inside the cartridge.

White paper: The effects of humidity on 3D printing filament and drying methods

How can humidity affect your 3D printing filaments and, therefore, the end quality of your prints? What can you do to protect your materials and ensure the best possible preservation conditions? Find it all in this comprehensive technical white paper, developed by the Engineering team at BCN3D.
  • Effect of environmental humidity on printability of hygroscopic filaments

    Print quality was tested with our most hygroscopic filaments, after recreating an environment with constant humidity and storing each spool for 4 days. PVA ensured good print results for a wide range of conditions, while PA and especially TPU required a much more restrictive storage protocol.

    Effect of environmental humidity on printability of hygroscopic filaments
  • Highly hygroscopic filaments: humidity limit of printability

    The humidity limit of printability was obtained after storing the filaments for 4 days at 25 ºC and specific relative humidity (RH). We observed that PVA could be printed successfully when stored at up to 40% RH. PA started to show superficial imperfection when stored at a 30% RH. TPU proved much sensitive to moisture and did not give satisfactory results when stored above 12% RH.

  • Highly hygroscopic filaments: Shelf life

    The three hygroscopic filaments under test underwent a kinetic absorption evaluation. When stored at typical humidity conditions (60% RH), each filament required a different amount of time to reach its printability limit. We calculated that PVA could be kept on an unprotected shelf for up to 12 hours before requiring a drying cycle. PA shelf life was estimated at 4 hours, which makes it unsuitable to very long prints. According to our calculation, TPU should be handled carefully, as its extrusion performances started decaying after only 1.5 hours.

    Get the best finish

    Hygroscopicity, the tendency to absorb moisture, is a great enemy of 3D printing, as it is a prominent characteristic of most thermoplastic materials. Even a small percentage of humidity can negatively affect most filaments and, therefore, the end result of the print job, not only through imperfections which appear on the print surface, but also damaging its mechanical properties. Correctly storing your filament will have, then, a significant effect in the overall quality of your printed parts.

    Tested Sample: BCN3D PA (polyamide)


    Rough surface, opaque appearance and much stringing 3D printing sample

    Spool stored 4 days in an environment with high levels of humidity. Over extrusion and poor accuracy. Rough surface, opaque appearance and much stringing are an indication of an irregular extrusion and poor interlayer adhesion.

    Spool stored 4 days in a workspace environment with 40-60% relative humidity. Good extrusion and dimensional accuracy, but rougher surface, due to the formation of vapor micro-bubbles.

    Spool correctly stored in the dehumidifier of the BCN3D Smart Cabinet. Continuous extrusion without interruptions or formation of vapour bubbles. Smooth surface and no stringing.

    Print while in storage

    The dehumidifier can fit up to 10 small spools (weight between 750 g - 1 kg and width up to 55mm) or 4 big spools (weight up to 2,5kg). These can be loaded to your 3D printer directly from this humidity-controlled environment, therefore allowing it to print while keeping the materials in perfect condition.


    Benefits of the Smart Cabinet compared to other drying methods:

    BCN3D Smart Cabinet:

    • Optimal for all materials
    • Low Energy consumption: 12 W Avg / 100 W Max
    • 10 storage slots for small filament spools (4 for big spools)
    • Prints while in dry storage
    • Humidity-controlled environment, dries without heat
    • No consumable parts

    Other systems:

    Oven Baking:

    High energy costs, decreases tensile strength, time-consuming, melts filament if too hot.

    Desiccants:

    No RH control, constant replacement, and maintenance.

    AC & Dehumidifier:

    High energy costs, unable to reach below 40% RH, ineffective in low temperature/winter conditions.

    Other Filament Dryers:

    Constant heat baking with high energy consumption, unable to dry for extended periods, only able to dry a few spools at a time.
