Why do we at Winkle vacuum pack our coils?

Under-extrusion is the most common printing problem in 3D printing. It is related to the presence of moisture in the filament. If the coil is not dry, you may experience poor quality prints.
How to know if the filament is wet?

• The first way to detect its condition is to see that the material is not smooth and contains small bubbles inside. These are formed by the evaporation process of the moisture already stored inside the material, eventually producing steam inside the filament.
• You can also detect that the filament is wet if the material continues to extrude, even though the extrusion motor has stopped pushing through the printer’s fuser.

What are the main consequences of making 3D prints with filaments in poor condition?
● The extrusion lines are irregular and even have cracks or gaps between them. ● The parts do not adhere well to each other. ● The printed parts break easily. ● It can cause stringing, or the appearance of “threads” in your prints. ● The Hotend can get jammed.

How to prevent moisture in the filament

Before shipping, at Winkle we carry out the vacuum packaging process of the coils in order to preserve all the properties of the product.

• Filament dryer: There are devices specifically designed to dry filament. These devices not only remove moisture from the filament, but also keep it in optimal conditions for printing. Some models allow you to dry the filament while it is being printed.
• Oven: Another option is to use a home oven to dry the filament. If you decide to do this, it is important to use an external thermometer to ensure that the temperature is appropriate, as temperature variations in conventional ovens can damage the material.
• Food dehydrator: Food dehydrators can also be useful for drying 3D printing filament. You just need to make sure that the temperature of the dehydrator is correct for the type of material you want to dry.
