The SUNLU FilaDryer E2 combines filament drying and annealing for 3D-printing materials. Select the destination version that matches your local power requirements.

Before you use it

Its working temperature range is 35–110°C. Check the filament and spool temperature limits before heating. Annealing can change part dimensions; test a small sample and allow for shrinkage.

Spool fit and regional versions

Check spool dimensions against the stated 250 mm diameter and 153 mm width limit. Regional stock is shown separately. A sold-out destination option cannot be ordered.

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 FilaDryer E2 delivers — a professional-grade 2-in-1 annealing and drying solution specifically designed for Engineering Materials.

How to Anneal?

  1. Select the Temperature: Determine the right temperature based on the material.
  2. Control Heating Rate: Ensure the part is evenly heated.
  3. Maintain a Constant Temperature: Adjust the duration according to the size and material.
  4. Manage Cooling: Allow for gradual cooling or use controlled cooling for the best results.

Tips for Successful Annealing!

  • Precise temperature control is essential to avoid overheating.
  • Test with small models first to reduce trial-and-error costs.
  • Allow for shrinkage, and adjust your design accordingly.

No More Worries about Safety?

Intelligent protection system, an alarm beep will sound if the temperature exceeds the preset value by 10°C or the machine continues to work improperly.

Temperature control, 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℃.

All-round protection of the machine and personal safety by fireproof grade materials.

Where we ship and shipping charges

Shipping availability depends on the product, supplier, and delivery address. Enter your address at checkout to see the available shipping options and final shipping charge before payment. If no shipping option is offered for your address, we cannot ship that combination of items to that destination. A shipping zone does not mean every product is available in every location.

Fulfillment through our partners

Apex Technica works with fulfillment partners, including suppliers through Shopify Collective, who ship products directly to customers. An order containing products from different suppliers may ship in separate packages. Shipping charges may be combined across packages; review the total at checkout.

Processing and delivery estimates

Order handling generally takes 3–5 business days before dispatch, but varies by supplier and product. Business days are Monday through Friday, excluding holidays. Carrier transit time is additional to handling time. Contact hello@apextechnica.com before ordering if you need an item-specific dispatch estimate or delivery by a particular date. For Collective products, available shipping rates and carrier transit estimates are calculated at checkout. Carrier transit estimates describe time in transit after dispatch, not a guaranteed order-to-delivery date. Weekends, holidays, carrier disruptions, and customs processing can affect delivery.

Tracking and separate shipments

We send shipping confirmation and tracking details when they become available from the fulfillment partner. Separate shipments may have different tracking numbers and arrive on different days. Tracking can take time to show the carrier's first scan.

Address changes, delays, and delivery problems

Check your address before placing an order. Contact Apex Technica promptly to request a correction or cancellation; changes may be unavailable once processing begins. If a shipment is delayed, missing, damaged, or incorrect, contact us with your order number so we can investigate with the supplier or carrier. Do not send an item back without return instructions. See our return and refund policy.

Refund policy

30-day returns — exception for Collective supplier fulfillment

Apex Technica accepts return requests for products fulfilled by Apex Technica within 30 calendar days after delivery. This standard 30-day return window does not apply to products fulfilled by our Shopify Collective suppliers. Collective-fulfilled products are subject to the applicable supplier's return eligibility, return window, condition requirements, and fees, which may differ from our standard policy.

Products fulfilled by Collective suppliers

Review any supplier-specific return terms shown on the product page before purchasing. If those terms are not shown, contact hello@apextechnica.com before placing your order to confirm the applicable return window, eligibility, shipping costs, and any restocking fee. The exception does not mean that every Collective product is non-returnable. Apex Technica remains your contact for return requests and will coordinate with the supplier. Do not send products directly to a supplier without our return instructions.

Condition for standard Apex returns

For products covered by our standard 30-day policy, items must be unused, in their original packaging, and include all accessories and proof of purchase. This condition requirement does not prevent you from reporting a damaged, defective, or incorrect product.

How to request a return

Email hello@apextechnica.com with your order number, the item you want to return, and the reason for the request. Include photos if the item arrived damaged, defective, or incorrect. We will review the request and provide authorization, the correct return address, and shipping instructions. Returns are made by mail; items from different suppliers may require separate return shipments. Please retain tracking and proof of shipment.

Return costs

For standard Apex returns due to a change of mind, the customer pays return shipping and original shipping charges are not refundable. We do not charge a restocking fee for eligible standard Apex returns. For damaged, defective, or incorrect items, contact us so we can arrange the appropriate return or other resolution without charging you return shipping. For Collective-fulfilled change-of-mind returns, supplier-specific shipping and restocking terms apply.

Refunds and exchanges

After the authorized return is received and inspected, we will notify you of the outcome. Approved refunds are issued to the original payment method within 10 business days after receipt and inspection. Your bank or payment provider may require additional time to post the credit. Any applicable, previously disclosed return charges will be explained. For exchanges, contact us to arrange a return and a separate new order; replacement availability is not guaranteed.

Damaged, defective, incorrect, or missing items

Contact Apex Technica promptly if your order arrives damaged or incorrect, has a defect, or does not arrive. We will investigate with the supplier or carrier and explain the available resolution. Manufacturer warranty coverage is separate from this return policy. Nothing in this policy or a supplier exception limits rights that cannot be excluded under applicable law.
