Bulk Filament Implementation and the Importance of FIFO in 3D Printing

[Hermione]

Implementing bulk filament storage is a smart approach for large-scale 3D printing operations, especially when dealing with high print volumes or frequent production runs. However, to ensure efficiency and maintain material quality, following a structured inventory management system like First-In, First-Out (FIFO) is essential.

 

What is FIFO and Why Is It Important?
FIFO is an inventory management method where the oldest stock (first-in) is used first (first-out). When applied to 3D printing bulk filament, this system ensures that the earliest purchased or produced filaments are used before newer stock. Implementing FIFO prevents older filaments from sitting unused for extended periods, which can degrade material quality due to exposure to moisture or light.

In 3D printing, where filament quality directly impacts print performance, adhering to FIFO ensures consistency and reduces material waste. Over time, filament can absorb moisture from the environment, particularly hygroscopic materials like PLA and nylon. When these filaments are not stored properly or used promptly, they may degrade, leading to poor extrusion, bubbling, or even failed prints.

 

How to Implement FIFO in Bulk Filament Storage
To implement FIFO for bulk filament, it’s important to organize and label filament spools according to their purchase or production dates. Here’s a step-by-step guide:

Label Filament Spools: Upon receiving new filament spools, label each with the date of arrival or production. This will allow you to easily identify which spools should be used first.

Storage Organization: Arrange your storage area so that older filaments are placed in front or on top, making them easier to access. Design a clear system where new filament stock is added to the back or bottom of the storage unit.

Monitor Material Condition: Regularly check filament spools for signs of moisture absorption or brittleness. Even when following FIFO, ensure that all filaments are stored in dry, temperature-controlled environments, such as sealed containers with desiccant packs.

Track Usage: Use inventory management software or a manual log to track the consumption of filament spools. This will help you maintain an accurate view of which materials are being used and when new stock needs to be ordered.

 

Benefits of FIFO in 3D Printing Operations
The FIFO method helps in minimizing material waste, maintaining high print quality, and reducing unexpected filament failures during production. Additionally, this system enhances efficiency, allowing 3D printing businesses to streamline their operations by ensuring that older stock is used promptly.

 

By implementing FIFO in your bulk filament storage system, you can keep material quality consistent, reduce waste, and maximize the efficiency of your 3D printing workflow.
