It actively dries filament during printing with a low-energy 25W system, preventing moisture-related print defects like popping and stringing. Designed for PLA, PETG, and TPU, it includes breathable vents to expel humidity and polished brass ports for smooth filament feeding. Its collapsible design makes it ideal for space-conscious professionals seeking reliable, continuous filament drying. ## Description desertcart.com: Martronic 3D Printer Filament Dryer & Active Feeder | Print-While-Drying Spool Holder | 25W Continuous Silent Filament Warmer | Optimized for PLA/PETG/TPU | Dust-Proof & Portable : Industrial & Scientific ## Features - 【Active "Print-While-Drying" System – The 24/7 Bodyguard for Your Prints】Don't let moisture ruin a 30-hour print at the last minute. Unlike storage boxes that just sit there, this is an Active Feeder that works while you print. It acts like a heated shield, warming the filament right before it enters your printer to stop "popping" and stringing. Note: Think of this as a "Dryer," not a "Storage Bin." Use it to improve print quality, but please put filament back in a sealed bag for long-term storage. - 【Advanced Graphene Tech – "Surround Sound" Heating, No Hot Spots】Old-school dryers use harsh metal coils (like a toaster) that can melt your spool if you aren't careful. We use advanced Carbon Fiber Graphene technology. Imagine a gentle "heated blanket" wrapping around your filament—it heats up evenly and instantly without dangerous hot spots. It is factory-tuned to the perfect "Safe Zone" for PLA and PETG, so you get perfect drying without ever needing to fiddle with settings. - 【25W Eco-Power – Runs on "Pennies" a Day】 Why use a power-hungry 100W machine for a simple job? Our 25W Graphene Core is ultra-efficient, using less energy than a standard lightbulb. This means you can safely leave it running for 2-3 day marathon prints without worrying about your electric bill or tripping a breaker. It’s the "Always-On" solution that saves you money while saving your prints. - 【Vented "Breathable" Design – Don't Steam Your Filament】Drying wet clothes in a sealed plastic bag doesn't work—the water has nowhere to go. The same applies here. Our dryer features a Breathable Fabric Vent that actively pushes humid air OUT of the box. If you feel warm air escaping near the zipper, that’s good! It means the moisture is leaving your filament instead of turning the box into a sauna. - 【Smooth Feeding & "Origami" Portable Design】We hate friction as much as you do. That’s why we use polished Brass Ports to let the filament glide smoothly into your printer, even with abrasive materials like Carbon Fiber. Tight on desk space? The whole unit is collapsible. It assembles in minutes for work and folds down flat like a thick shirt for travel or storage. Powerful enough to dry, yet small enough to fit anywhere. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0GHYSW6NQ | | Additional Features | Filament Dryer Box ON/OFF, Filament Dryer Box Plug-in, Filament Dryer Box with Dual Ports, Heated Filament Dryer Box, Portable Filament Dryer Box | | Best Sellers Rank | #52,537 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #752 in 3D Printing Filament #846 in 3D Printer Accessories | | Brand Name | Martronic | | Color | Black | | Customer Reviews | 3.8 3.8 out of 5 stars (27) | | Item Diameter | 9.84 Inches | | Item Weight | 1.32 Pounds | | Manufacturer | Martronic | | Manufacturer Part Number | Y031FilamentDryer | | Material Type | Carbon Fiber Graphene, Nylon | | Model Number | Y031FilamentDryer | | Number of Items | 1 | | Unit Count | 1.0 Count | | Warranty Description | 1 Year Manufacturer | ## Product Details - **Brand:** Martronic - **Color:** Black - **Item Diameter:** 9.84 Inches - **Item Weight:** 1.32 Pounds - **Material:** Carbon Fiber Graphene, Nylon ## Images ![3D Printer Filament Dryer & Active Feeder | Print-While-Drying Spool Holder | 25W Continuous Silent Filament Warmer | Optimized for PLA/PETG/TPU | Dust-Proof & Portable - Image 1](https://m.media-amazon.com/images/I/81+3fLUrnyL.jpg) ## Questions & Answers **Q: Q1: Can I use this dryer while printing at the same time?** A: A: Yes! That's the core feature — the Martronic dryer feeds filament directly to your printer while keeping it warm. No need to pre-dry separately. **Q: Q2: Is this good for Bambu Lab / Ender 3 / Creality printers?** A: A: Yes, works with all standard FDM 3D printers. The PTFE tube feeds through brass ports that accommodate 1.75mm filament from any major brand. **Q: Q3: Does this work for TPU flexible filament?** A: A: Yes, the 25W graphene heating is gentle enough for TPU. It warms the filament to prevent moisture-related stringing without overheating. **Q: Q4: Can I control the temperature?** A: A: The dryer is factory-tuned to the optimal safe zone for PLA, PETG, and TPU — no fiddling with settings needed. Just turn it on and print. **Q: Q5: Is it really silent? Will this work with carbon fiber filament?** A: A: Yes, unlike traditional coil-based dryers that hum or click, our graphene core produces zero mechanical noise. Yes! The polished brass feed ports resist wear from abrasive materials like carbon fiber, wood-fill, and metal-fill filaments. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/806758598-3d-printer-filament-dryer-and-active-feeder-print-while-drying](https://www.desertcart.jp/products/806758598-3d-printer-filament-dryer-and-active-feeder-print-while-drying) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-31*
