30日間の返品・交換申請期間

Please contact us within 30 days after delivery to request a return or exchange. Requests made after this window may be declined unless required by law or a separate written agreement.
Returned products must be reviewed and approved before shipment back to DD3. Items should normally be unused, unopened where applicable, in original packaging and supported by receipt, invoice or other purchase proof.

Inspect cartons, spools, packaging, labels, colors, quantities and visible product condition promptly after delivery. If there is damage, shortage, wrong item or suspected defect, keep the packaging and logistics materials for evidence.
For shipping damage or quality issues, photos, videos, carton labels, batch labels, tracking records and print-test details help us evaluate the issue faster.

Before returning any product, contact WhatsApp ：+1 (626) 890-1292 or WhatsApp ：+1 (626) 693-1487 with order number, invoice or platform order ID, SKU or product name, material, color, quantity, problem description, photos or videos, and whether you request replacement, refund, credit or another solution.
Unauthorized returns may not be accepted. Return address, carrier method and packing instructions will be provided only after review and approval.

If DD3 confirms that we shipped the wrong item, supplied a defective product, packed the wrong confirmed specification, or that damage occurred before delivery due to DD3 responsibility, we may offer replacement, refund, store/account credit, price adjustment, spare goods, replenishment in a later shipment or another reasonable solution.
For B2B, OEM, wholesale and export orders, the solution may depend on confirmed specifications, batch evidence, inspection results, logistics records, usage condition and the written quotation or invoice terms.

If the customer ordered the wrong item, changed their mind, provided incorrect specifications, used unsuitable printer settings, stored filament improperly, missed import requirements, or no longer wants the goods, return or exchange is subject to DD3 review and written approval.
For customer-responsibility returns, the customer may need to pay return shipping, replacement shipping, customs, taxes, handling, payment fees and other related costs. Original shipping, customs and import charges are normally non-refundable.

Custom colors, OEM/private-label packaging, special orders, opened or used spools, products affected by customer storage or handling, and bulk goods produced or packed according to confirmed specifications may be non-returnable unless a confirmed DD3 quality issue exists.
Large-volume B2B/export orders, discounted clearance items, samples and goods sold through third-party platforms may have additional restrictions stated in the quotation, invoice, platform policy or written agreement.

If you need to cancel an order, contact us as early as possible. Cancellation may be discussed before production, packing or shipment begins.
After production, custom packing, handover to carrier, export booking or shipment, cancellation may not be possible and the matter will be handled under return/exchange or written order terms.

After an approved return is received and inspected, we usually process approved refunds within 3–6 business days. Banks, PayPal, credit card networks or other payment providers may require additional time to post the refund.
Refunds are normally returned to the original payment method where practical. PayPal fees, credit card fees, bank charges, currency conversion differences, shipping, duties or import costs may be handled according to the payment provider rules and written order terms.

If you purchased through a third-party marketplace, distributor, reseller or procurement platform, please request returns, refunds or disputes through that platform or seller first, because platform rules and payment flows may control the process.

Before initiating a chargeback or payment dispute, please contact us so both parties can review quotation, invoice, order confirmation, payment record, tracking, delivery proof, photos, videos, batch information, return communication and quality evidence.
We reserve the right to provide relevant transaction and logistics evidence to payment providers, card networks, PayPal, platforms or legal advisers when responding to a dispute.

For return, exchange, refund, cancellation or quality claim support, contact WhatsApp ：+1 (626) 890-1292 or WhatsApp ：+1 (626) 693-1487.
