Now the Sunlu E2 filament dryer is available for $287.99 on Amazon. Additionally the E2 listing also shows an extra 10% off when you add a qualifying engineering filament to the order, and that discount is enough that you get a filament spool, for example Easy PA, effectively for free.
The Sunlu FilaDryer E2 is different from a simple filament dryer because it is built to anneal printed parts, not just dry filament (it also can do that of course). Annealing means holding a printed part at a controlled temperature below its melting point to reduce internal stress and improve properties like heat resistance and dimensional stability, which is mainly relevant for engineering filaments. To do that, the E2 can reach about 230°F, which is above the roughly 120 to 160°F range of common filament dryers, which are fine for drying PLA or PETG. This makes it useful for materials like nylon, PC, ASA, and reinforced filaments.
- ①【SUNLU Dry & Anneal 2-in-1 FilaDryer】- E2 Filament Dryer combines drying and annealing in one, 110℃ max temperature, designed for engineered materials. Push the limits of 3D creation with this all-in-one solution.
- ②【First Annealing FilaDryer】- 110°C Annealing Chamber: Unlocks 99.99% of engineering materials' full potential—PA, PC, Nylon (GF/CF variants), and more—for ultra-tough, impact-resistant prints. Ideal for high-performance applications
- ③【500W PTC Heater】- SUNLU filament dryer E2 is equipped with a 500W PTC heater, 325W rated power, heating to 70°C only 30 min. Offering a high heating efficiency (30% higher than the FilaDryer S4).
- ④【Why We Need Annealing】- Annealing heats 3D-printed plastic parts to relax internal molecular stresses, then slowly cools them, enhancing strength and dimensional stability. Use SUNLU E2 Filament Dryer to help you create efficiently and unlimitedly.
- ⑤【Dual-Chamber Power Saver 】- Ultra-Airtight Dryer E2, features a one-piece silicone plug and dual-chamber heating. The innovative closure system enables simultaneous annealing and drying in one machine, with superior moisture isolation and thermal insulation.
