The Sovol SH03 Filament Dryer helps stop 3D printing problems. It removes water from your filament before you print. Water in filament can make prints weak. It can also make the surface look bad. Sometimes, it even makes odd noises while printing. Studies show that more water makes materials like PEEK weaker. It lowers their strength, density, and hardness. Nylon can lose up to 60% of its bending strength after taking in water.

- Follow good ways to dry filament, like checking the heat and how long you dry it. This helps prints work well and stops failures.
Moisture and Its Impact on Print Quality

Why Filament Absorbs Moisture
Sometimes, your filament does not print as you want. This can happen because of moisture. Filament takes in water from the air. Many 3d printing materials, like nylon, are hygroscopic. They pull in water from the air very fast. How fast this happens depends on humidity and temperature. When the air is humid, filament gets wet faster. Even a short time in a humid room can change your filament.
- Nylon takes in water quickly, which changes how it works.
- High humidity makes filament soak up more water.
- Moisture makes filament weaker and less stiff.
- Wet filament can make prints look bad and weak.
You might think printer settings are wrong when prints fail. But often, wet filament is the real problem. If you hear popping or see bubbles, moisture is probably the cause.
Tip: Keep filament in a dry place to slow down water absorption. Use sealed boxes or filament dryers for best results.
Effects of Moisture on Different Filament Types
Different filaments react to water in their own ways. Some get wet fast, while others do not. The table below shows how some filaments act with water and humidity:
|
Filament |
Moisture Absorption Characteristics |
|---|---|
|
ABS |
Can get wet, which causes bubbles and bad prints. |
|
Nylon |
Gets wet easily, which hurts strength and print quality. |
|
PETG |
Can take in water, but details are not given. |
High humidity can make filament take in up to 0.05% of its weight in water in less than two hours. This can make it up to 30% weaker in one way and up to 70% weaker in another. If water goes above 0.10% by weight, ductility goes up, but so does porosity, which can make prints weak.
You need to watch out for water in filament to keep your prints strong and good. Dry filament gives you better looking and more reliable prints.
Common Failures Caused by Wet Filament

If your filament gets wet, your prints can fail. These failures waste your time and material. Knowing how moisture hurts filament helps you spot problems early. You can stop these issues before they start. The sh03 filament dryer removes water from filament before you print.
Stringing and Oozing
Stringing and oozing happen when thin plastic strands stretch between parts. You might see extra strings or messy spots on your print. Wet filament is a big reason for this problem. When filament gets wet, water inside turns to steam in the hot nozzle. The steam pushes out melted plastic in strange ways. This happens a lot with PETG, Nylon, and TPU.
- Filament gets wet fast in humid rooms.
- Steam from wet filament causes stringing and oozing.
- You might see thin strands between printed parts.
- Keep filament in airtight boxes or use the sh03 filament dryer to stop this.
Tip: Dry your filament before printing to stop stringing and oozing. The sh03 filament dryer makes drying easy and works well.
Bubbling, Popping, and Weak Prints
Bubbling and popping sounds mean your filament is wet. When wet filament heats up, water turns to steam and escapes. This makes bubbles in the melted plastic. Prints can end up rough and weak.
- Bubbling and oozing happen when steam forms bubbles inside filament.
- These bubbles make the plastic come out uneven and leave marks.
- Weak layers form because the material does not stick well.
- Some filaments, like nylon, snap and break if they get wet.
You might hear popping or hissing as you print. These sounds mean there is water in your filament. The sh03 filament dryer takes out the water and helps you avoid these problems.
Surface Defects and Layer Adhesion Issues
Wet filament can make your prints look rough and weak. You might see bumpy or uneven surfaces. Sometimes, prints do not stick to the bed. Steam bubbles mess up the flow of plastic and cause these problems.
- Prints can peel off or warp at the corners.
- Corners may lift, and parts can break off while printing.
- Stringing and oozing leave blobs and strings on the surface.
- Bubbling makes tiny bubbles that make the print rough.
- Uneven plastic flow causes blotchy or patchy spots.
Note: Drying filament with the sh03 filament dryer makes prints smoother and stronger. Removing water gives you better looking and tougher prints.
Moisture causes many failed prints in 3d printing. You can stop these failures by keeping filament dry and using the sh03 filament dryer. Dry filament gives you better prints and more success.
Identifying Moisture Problems in Filament

Visual and Audible Signs
You can find moisture problems in filament by using your senses. First, touch the filament with your fingers. Dry filament feels smooth and hard. Wet filament feels sticky or soft. You might see the color or texture change. Sometimes, you can spot swelling or tiny water drops on the filament. These things show that humidity has hurt your filament.
Listen when you start printing. If you hear popping or crackling, there is water inside. Hissing or sizzling means water is turning to steam. Clicking from the extruder shows the filament is not moving right. These sounds happen when humidity makes the filament swell or get soft.
- Change in texture: Wet filament feels sticky, not smooth.
- Unusual sounds: Popping, crackling, or hissing during printing.
- Visual cues: Condensation, discoloration, or swelling on the filament.
Tip: Always check how your filament looks and sounds before printing.
Troubleshooting Print Quality Issues
If your 3d prints look bad, check for moisture. Look for rough, bubbly, or uneven spots on your prints. Stringy or blobby lines mean the filament took in water. A dull and patchy finish can also mean there is moisture. If you see the filament spit or smoke a little, water is inside.
You can test your filament by drying a small piece for a few hours at 45–50 °C. Print again with the dry filament. If your print looks better, moisture was the problem. This easy test helps you know if water is causing trouble.
- Rough or bubbly print surfaces
- Stringy or blobby lines instead of smooth ones
- Matte, uneven finish on prints
- Pops, hisses, or smoke during extrusion
Note: Check and dry your filament often to stop moisture problems and keep it working well.
Why Drying Filament Matters for Print Quality

Passive Storage vs. Active Drying
It is important to know how storage affects filament. Passive storage means you put filament in sealed boxes or bags. Silica gel helps keep new water out. This stops more moisture from getting in. But passive storage cannot take out water already inside. If filament has soaked up water, you need active drying.
Active drying uses heat to get rid of trapped water. Filament dryers make the right conditions for water to leave. This brings filament back to how it should be. It helps prints look and work better. You get better results if you dry filament before you print.
|
Method |
What It Does |
When to Use |
|---|---|---|
|
Passive Storage |
Stops new moisture from entering filament |
For unused, dry filament |
|
Active Drying |
Removes moisture already inside filament |
For filament that feels wet or prints poorly |
Tip: Use passive storage for new filament. Use active drying if filament feels wet or prints badly.
Benefits of Properly Dried Filament
Drying filament helps you get better 3d prints. Water in filament can make parts weak and rough. It can also cause prints to fail. When filament has water, steam forms as you print. Steam makes bubbles that hurt the print and mess up the surface. Wet nylon can lose up to 40% of its stiffness. This makes your finished print lower quality.
Dry filament gives you better prints and fewer problems. Here are some good things about drying filament:
- Prints are stronger, smoother, and work better
- You waste less material and have fewer failed prints
- Print quality stays the same for every project
- Printing goes better and you get fewer surprises
- You hear less popping and get fewer weak spots from steam bubbles
Always check your filament before you print. Keep filament in a dry place. Use a filament dryer to dry filament well. Taking care of filament helps you get great results and nice-looking prints.
Note: Drying filament and storing it right helps keep print quality high. It stops moisture from hurting your projects.
