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.

Performance

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.

Protection
Protection

Protection

Protect your equipment and your work against power outages thanks to the Uninterruptible Power Supply (UPS), providing 2 minutes of additional print time before a blackout, time enough for the 3D printer to return automatically to the home position.

Integration

Full 3D printing solution. The Smart Cabinet integrates with your 3D printers, materials, and software, streamlining your workflow thanks to its fast and easy loading of up to eight filament spools and its wheeled structure, which enables effortless transportation across your facilities.
  • 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.

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

    Spool stored 4 days at 70% RH. 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 at 30% RH. 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 8 small spools (between 750g - 1kg) or 4 big spools (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
    • 8 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.
