What Is the Comgrow SH02 Filament Dryer Box?

Comgrow SH02 Filament Dryer Box Review

The Comgrow SH02 Filament Dryer Box is a sealed storage and drying solution for 3D printer filament. It holds two 1KG spools and works with various filament types like PLA, PETG, TPU, and ABS. With a 150W PTC fast heater and a user-friendly touch screen, it’s designed to keep your filament dry and ready for flawless prints. Whether you’re a hobbyist or running a print farm, this dryer box promises to improve print quality and save time.

Why You Need a Filament Dryer Box

Moisture is the enemy of 3D printing. Filaments like PLA and PETG absorb water from the air, leading to poor layer adhesion, stringing, and brittle prints. A filament dryer box like the SH02 removes moisture, ensuring consistent results. Curious about filament types? Check out our guide on PLA vs. ABS vs. PETG to learn more.

Our Experience with the Comgrow SH02 Filament Dryer Box

We’ve been using the Comgrow SH02 Filament Dryer Box for a few months now, and it’s transformed our 3D printing workflow. When we first got it, we were thrilled with how easy it was to set up. The touch screen is super intuitive, and the one-key settings for filaments like PLA and PETG saved us a ton of time. We dried two spools at once for a multi-material project, and the results were night and day—smoother prints, better layer adhesion, and no more stringing. It’s been a lifesaver for our 3D-printed decor projects.

That said, the fan noise caught us off guard. It’s loud, like a constant high-pitched hum, and it’s noticeable in our small workspace. We ended up moving it to a corner and using a 3D printer enclosure to dampen the sound. Also, we noticed the humidity sensor isn’t always accurate. It showed higher humidity even after hours of drying, so we started cracking the lid open slightly, which helped a lot. The venting could definitely be better—the tiny top vent doesn’t cut it.

We had a minor issue with the touch screen flexing when we pressed it, which made us worry about durability, but it’s held up so far. When we reached out to Comgrow’s customer service about the noise, they were quick to respond and offered helpful tips, which we appreciated. Overall, for $68.99, we think it’s a steal for what it does, especially compared to pricier brands. It’s not perfect, but it’s boosted our print quality significantly.

How to Get the Most Out of Your Comgrow SH02 Filament Dryer Box

To maximize the Comgrow SH02 Filament Dryer Box’s performance, follow these tips:

  • Crack the Lid: Open the lid slightly during drying to improve airflow and reduce humidity buildup.
  • Use Spool Holders: 3D print custom spool holders for cardboard spools to ensure smooth feeding, especially when printing while drying.
  • Monitor Temperature: Use the one-key settings for your filament type, but double-check the temperature for sensitive materials like TPU. Learn more about TPU in our TPU filament guide.
  • Place in a Quiet Area: If the fan noise bothers you, keep the dryer in a separate room or use noise-dampening accessories.

FAQs About the Comgrow SH02 Filament Dryer Box

Can the Comgrow SH02 Filament Dryer Box dry two different filament types at once?

Is the Comgrow SH02 compatible with Bowden-style 3D printers?

Yes, the SH02’s filament holes are designed for PTFE tubes, making it suitable for Bowden setups. Some users may need to adjust the hole angle for direct-drive printers.

How loud is the Comgrow SH02 Filament Dryer Box?

The fan produces around 60 dB, similar to a loud conversation. It’s noticeable in quiet spaces, so consider placing it away from your workspace.

Does the Comgrow SH02 Filament Dryer Box work with 2.85mm filaments?

Yes, it’s compatible with both 1.75mm and 2.85mm filaments, including PLA, PETG, TPU, and ABS.

How long should I dry filament in the Comgrow SH02?

Drying times vary by filament. PLA typically needs 4-6 hours at 45°C, while PETG may require 6-8 hours at 55°C. Check the one-key settings for guidance.

Conclusion: Is the Comgrow SH02 Filament Dryer Box Worth It?

The Comgrow SH02 Filament Dryer Box is a fantastic choice for 3D printing enthusiasts on a budget. Its dual-spool capacity, fast PTC heater, and sealed storage make it a versatile tool for improving print quality. While the loud fan and venting issues are drawbacks, workarounds like cracking the lid and using noise-dampening solutions can mitigate these flaws. For $68.99, it’s hard to beat the value, especially compared to pricier options like the Sunlu Filadryer S4.

If you’re serious about 3D printing decor, whether it’s Easter decorations or custom lighting, the SH02 ensures your filament is ready for flawless results. It’s not perfect, but it’s a solid winner for most hobbyists.
