Return & Refund Policy

Effective Date: September 19, 2025

Thank you for choosing DT 3D Printing. We take pride in the quality of our products and want you to be completely satisfied with your purchase. This policy outlines our guidelines for returns, refunds, and exchanges.

1. Returns & Refunds

Due to thecustom-made nature of our 3D printed products, we generally do not accept returns for items without quality issues. Returns are accepted only under the following circumstances:

  • Manufacturing Defects or Quality Issues
    • Coverage: Severe dimensional inaccuracies (beyond the agreed tolerances), structural failures (such as significant cracks), major surface imperfections, use of incorrect materials, or products that do not match the confirmed drawings/specifications.
    • Process:
      1. Contact Us: Please contact our customer service within 7 working days of receiving your order, providing your order number and clear photos/videos of the issue.
      2. Assessment: Our quality control team will evaluate your claim within 3-5 working days and inform you of the result.
      3. Resolution:
        • Defect Confirmed: We will offer a free reprint or a full refund, and we will cover the cost of return shipping.
        • Negotiation: If the issue does not affect the core functionality, we may offer a partial refund as compensation.
  • Damaged in Transit
    • Process: Please inspect your package upon delivery. If you find any damage to the packaging or the product, please take photos immediately, ask the courier to note the damage, and contact our customer service right away. We will assist you with the insurance claim and arrange a reprint or refund.
  • Incorrect or Missing Items
    • Process: Please contact us within 3 working days of receiving your order. After verification, we will send the correct items or the missing parts to you free of charge.

2. Exchanges & Repairs

For issues not related to quality, we offer the followingpaid services:

  • Design Modifications: If you need to adjust your design, we will charge the standard fees for the new design and printing.
  • Surface Finish Upgrades: If you wish to change or upgrade the surface finish (e.g., from matte to polished), we will charge the corresponding secondary processing fee.
  • Dimensional Adjustments: If minor size adjustments are needed, we will charge for the reprinting or partial reworking as appropriate.

3. Non-Returnable Items

The following items arenot eligible for return or refund:

  • Claims made after the 7 working day inspection period.
  • Products that fail due to issues with the provided 3D model file (e.g., poor design, insufficient wall thickness).
  • Returns requested due to subjective reasons (e.g., “change of mind,” “does not look like I imagined,” “no longer needed”).
  • Products that have been used, modified, or damaged by the customer.
  • Minor imperfections inherent to the 3D printing process (such as slight layer lines or minor color variations) that were communicated prior to production.

4. Refund Processing

  • Once a refund is approved, we will process it within 3-5 working days.
  • The refund will be issued to the original payment method. The time it takes for the funds to appear in your account depends on your payment provider or bank.

5. Processing Time

  • The evaluation of all after-sales requests takes 3-5 working days.
  • The production time for reprints or repairs is the same as for a new order and depends on our current production schedule.
