SUNLU FilaDryer E2, Up to 110℃, Professional Drying and Annealing, Born for Engineering 3D Printing Filaments

£344.99 GBP
£318.99 GBP £344.99 GBP

[SUNLU FilaDryer E2] The newest pop-up in 2025, made for engineered materials, helps infinite creation, drying and annealing in one.

[Superior and Efficient Annealing] Up to 110°C, it can anneal 99.99% of engineering materials on the market, allowing the materials to fulfill their potential and giving your model excellent properties such as extraordinary impact resistance and toughness. Suitable for such as ABS, ABS-CF, ASA, PC, flame retardant PC, PC-ABS, PC-PBT, CoPA, PA6-GF, PA6-CF, PA12-CF, PA612-CF, PA12 etc...

[Fast and Efficient Drying] 500W PTC ultra-high heating power makes your creation a step faster. It takes only 20 minutes to heat up to 50℃ at room temperature and 30 minutes to heat up to 70℃! Temperature can reach up to 110℃ (high temperature drying needs to take into account the temperature resistance of the filament spool)

[Excellent Airtightness, Super Insulation Effect] One-piece silicone plug over the line hole, the cover plate is equipped with sealing silicone strips and magnetic suction block, to isolate the outside water vapor into the chamber. The all-round dual-chamber design at the top, middle and bottom realizes the heating temperature exceeding 100°C. Combined with the innovative closure system, the annealing process is more perfect, solving the two needs of annealing and drying in one machine.

[Extra Large Interior Space, Super Adaptability] The maximum compatible spool size is Φ250mm*153mm, which is suitable for most of the regular spools on the market. Tested, it can hold 2 reels of regular 1KG spools, 1 reel of regular 2KG spools or 2 reels of regular 3KG spools. (Note that the test spools are SUNLU spools, other brands of spools will have slight differences, but basically compatible, when using the need to pay attention to the size of the spool.)

[Strong Compatibility, Adapts to 99% of the use scenarios] Can be applied to both engineering materials and conventional materials. Built-in preset filament settings, one click to apply the preset. The wire diameter is compatible with most of the materials on the market (Φ1.75mm, Φ2.85mm), and the Teflon tubing included with the product is Φ4*Φ3mm in size and 8cm*2 and 1m*2 in length.

[Strong Safety, No More Worries] Intelligent protection system, two-level temperature control switch, over-temperature will be disconnected, cooling will be restored. Double-layer heat insulation, when the internal temperature is >100℃, the external touch temperature is only <60℃. Fireproof material grade

[Inspire Engineering Material Potential] Annealing significantly enhances the impact resistance and durability of engineering materials, allowing you to unlock engineering-grade performance in every creation, which can be applied to: drone accessories, helmets, screws and nuts, blower pipes, etc. Models that need to withstand high-intensity impact and durability.

What is Annealing & Why is it Necessary

Plastic products are placed in a heated liquid medium or hot air circulation box at a constant temperature for a period of time, and then slowly cooled to room temperature, using heat to accelerate the relaxation of macromolecules in the plastic, thus eliminating or reducing the residual stresses in the products after molding.

Eliminate the local stress concentration phenomenon produced by different cooling speeds during the cooling and curing process of plastic products.

That's what the SUNLU FilaDryer E2 delivers
— a professional-grade 2-in-1 annealing and drying solution specifically designed for Engineering Materials.
