Buyer: The person or company whose name, contact and billing details are entered with the order ("Buyer").

2. Subject

This agreement covers the sale and delivery of 3D printed parts ("Product") that the Buyer orders by uploading 3D models on the Quote Portal (quote.upcores.com) and that are made to the Buyer's own files and choices. If the Buyer is a consumer, Turkish Consumer Protection Law No. 6502 and the Regulation on Distance Contracts apply.

3. Product and Price

The Product's technology, material, quantity and options, its unit price, any discount and delivery cost, and the total including taxes are shown in the order summary and on the Pro Forma Invoice. The amount shown at payment applies.

4. Information Before the Order

The Buyer confirms having learned the Seller's identity and contact details, the Product's main characteristics, the total price including taxes, the payment and delivery details, the information on the right of withdrawal and the ways to complain from this text and the order summary before placing the order.

5. Formation of the Agreement

The agreement is formed when the Buyer accepts this text and completes the order. If the Seller finds that a file cannot be produced with the chosen material or method, it informs the Buyer. If the Buyer makes no change, the order is canceled and the amount received is refunded within 14 days at the latest.

6. Payment

Payment is made by credit or debit card on the iyzico secure payment page, or by bank transfer. The Seller does not store card details. With bank transfer, production starts when the amount reaches the Seller's account.

7. Delivery

The estimated production and shipping date is shown in the order summary. The Product is shipped by carrier to the address the Buyer gives. If delivery would exceed the legal 30-day period, the Buyer is informed and may terminate the agreement; the amount paid is then refunded within 14 days at the latest. The Buyer should check the package on delivery and have a report made for a damaged package.

8. The Buyer's Files and Responsibility

• The Buyer confirms holding the necessary rights to the uploaded files and that the parts to be produced are lawful.
• The design of the part and its fitness for the intended use are the Buyer's responsibility.
• The Seller uses the files only for quoting and production and keeps them confidential.

9. Right of Withdrawal

Because the Products are made to the Buyer's uploaded files and choices, they are goods prepared in line with the consumer's requests or personal needs under the Regulation on Distance Contracts, so there is no right of withdrawal. The Buyer may send a cancellation request to the Seller before production starts; if production has not started, the amount paid is refunded.

Consumer legislation does not apply to Buyers purchasing for commercial or professional purposes.

10. Defective Products

The Product is made with the technology and material in the order summary, within the usual tolerances of that production method. The Buyer reports a Product believed to be defective, with photos, to hello@upcores.com. Consumer Buyers have the rights set out in Law No. 6502: withdrawal from the agreement, a price reduction, free repair or replacement with a non-defective equivalent.

11. Force Majeure

For events beyond the parties' control, such as natural disasters, war, epidemics, strikes or a stopped supply chain, deadlines are postponed for as long as the event lasts. The parties inform each other without delay.

12. Personal Data

The Buyer's personal data is processed under Personal Data Protection Law No. 6698, as explained in the Privacy Policy.

13. Disputes

Turkish law applies to this agreement. Consumer Buyers may apply to the Consumer Arbitration Committee within the monetary limits the Ministry of Trade announces each year, and to the Consumer Court above those limits. For other Buyers, the İstanbul Courts and Enforcement Offices have jurisdiction.

14. Effect

This agreement takes effect when the Buyer ticks the box at the payment step and completes the order. The acceptance is recorded with the order. The Buyer can always reach this text on this page. If the English and Turkish texts differ, the Turkish text applies.
