General Terms and Conditions

These terms govern custom 3D printing and related services provided by Twin Layer 3D s.r.o., Company ID: 24897507. They apply to businesses (B2B) as well as consumers (B2C). Consumers have broader rights — where the regime differs, this is stated explicitly at the relevant point.

Who we are

The provider (contractor) is Twin Layer 3D s.r.o., Company ID: 24897507, with registered office in Mnichovo Hradiště, Czech Republic.

E-mail: info@twinlayer3d.cz, phone: +420 737 358 171.

We are not VAT payers.

What we offer

Custom 3D printing (FDM and SLA/MSLA technologies), 3D modeling and part design, reverse engineering and related services. Every order is individual — we manufacture to your specification and do not sell off-the-shelf goods.

In legal terms this is a contract for work under Section 2586 et seq. of Act No. 89/2012 Coll., the Civil Code (the "Civil Code").

Who these terms apply to

• Consumer (B2C) — an individual acting outside the scope of their business activity. They are protected by the Civil Code and by Act No. 634/1992 Coll., on Consumer Protection.
• Entrepreneur (B2B) — orders within the scope of their business activity (usually stating a company ID). Consumer-protection provisions do not apply to them.

Points marked "Consumers only (B2C)" do not apply to entrepreneurs; points marked "Entrepreneurs only (B2B)" do not apply to consumers.

How an order works

A contract is formed when both parties confirm the quote.

• Inquiry — send us a model or a description of what you need.
• Non-binding quote — we price the order concretely (material, technology, dimensions, deadline, delivery costs).
• Confirmation — after you approve the quote.
• Production — we make the order as agreed.
• Delivery — handover of the finished order.

Work is defective if it does not conform to the contract (Section 2615(1) of the Civil Code). That is why the quote describes the required properties as precisely as possible — material, dimensions and tolerances, intended use, colour and technology. We recommend checking the quote carefully before confirming it.

Price and payment

The price is set individually based on the model, material, quantity, print time and chosen technology (see Pricing). The specific price is always stated in the quote.

We are not VAT payers — the prices stated in the quote are final.

You can pay by bank transfer against an invoice, or in cash on personal handover of the order.

Deposit: for orders above CZK 10,000 we require a deposit of 50% of the order price. We issue a document for the deposit and set it off against the final invoice. We do not start production until the deposit is paid.

Delivery

We ship orders via Zásilkovna, Czech Post or a courier service (e.g. PPL, DPD). By arrangement, the order can also be handed over in person.

Delivery costs are borne by the customer according to the current price list of the chosen carrier. We state the amount in the quote before you confirm the order.

We agree the delivery date for each order and state it in the quote.

Materials and models supplied by the customer

Where you supply the input (3D model, CAD file, template):

• We check the input to the extent that can reasonably be required of us and notify you without undue delay if we find it unsuitable for the required result (Section 2594(1) of the Civil Code).
• If you insist on using the input even after being notified, we will ask you for written confirmation. In that case you have no rights arising from defects caused precisely by that unsuitability (Sections 2594(4) and 2102 of the Civil Code).
• If we fail to notify you although we could have identified the unsuitability with due care, we are liable for the defect even where it was caused by your input.

Where we design the model ourselves, we are responsible for the result conforming to the contract and to the purpose known to us.

Liability for defects

Work is defective if it does not conform to the contract (Section 2615(1) of the Civil Code).

• A defect must be notified without undue delay after it can be identified with sufficient care, and at the latest within 2 years of handover of the work (Section 2618 of the Civil Code).
• Notify obvious defects on acceptance. If you accept the work without reservation, a court need not grant you rights arising from obvious defects (Section 2605(2) of the Civil Code).

Consumers only (B2C): If a defect appears within 1 year of acceptance, the item is presumed to have been defective already on acceptance, unless the nature of the item or of the defect precludes this (Section 2161(5) of the Civil Code). During that period it is therefore for us to prove that the defect did not exist on acceptance. A consumer's rights arising from defective performance cannot be curtailed — any arrangement limiting them is disregarded (Section 1814(a) of the Civil Code).

Entrepreneurs only (B2B): The presumption of defectiveness under Section 2161(5) of the Civil Code does not apply. Inspect the work as soon as possible after acceptance (Section 2104 of the Civil Code) and notify any defect without undue delay after you could have identified it upon a timely inspection and with due care — otherwise a court will not grant you rights arising from defective performance (Section 2112(1) of the Civil Code).

Complaints

Submit a complaint to info@twinlayer3d.cz or at our registered office. Please describe the defect and attach photographic documentation.

Order of remedies (Section 2169 of the Civil Code): you may request repair or delivery of a new item; the choice is yours unless the chosen remedy is impossible or disproportionately costly. Only then does a reasonable discount or withdrawal from the contract come into play — in particular where we refuse to remove the defect, fail to remove it in time, where the defect recurs, where it is a material breach of contract, or where there are multiple defects. Withdrawal is not available for an insignificant defect (Section 2171 of the Civil Code).

Custom-manufacturing specifics: for made-to-order work, delivery of a new item may not be possible. In that case repair, a reasonable discount or withdrawal from the contract applies.

Consumers only (B2C):

• We decide on a complaint immediately, or within 3 working days in complex cases. The time needed for an expert assessment of the defect is not counted into this period.
• We will settle the complaint at the latest within 30 days of the day it is submitted, unless we agree a longer period with you (Section 19(3) of the Consumer Protection Act). If that period lapses in vain, you have the right to withdraw from the contract or to request a new item.
• We will issue you written confirmation of the submission of the complaint and of the manner of its settlement (Section 19 of the Consumer Protection Act).

Withdrawal from the contract — consumers only (B2C)

We manufacture exclusively to order according to your individual specification.

The consumer acknowledges that, in accordance with Section 1837(d) of Act No. 89/2012 Coll., the Civil Code, they have no right to withdraw from the contract within 14 days, because the subject of performance is goods made to order according to their requirements or adapted to their personal needs (a 3D model and/or print produced according to the customer's individual specification). The customer expressly confirms this before completing the order.

We will expressly point this out to you before you confirm the order and will ask you to confirm it.

Where the subject of performance is a service (for example the design of the model itself) and we perform it with your prior express consent before the 14-day period expires, the right to withdraw ceases to exist (Section 1837(a) of the Civil Code).

Where, exceptionally, the goods are not made to order according to your individual specification — for example where you only select from predefined variants — your right to withdraw within 14 days remains. We will always tell you in the quote, before you confirm it, which regime applies to your order.

Copyright and order content

Inputs you supply:

The customer represents and is responsible for being entitled to provide the contractor with the inputs (3D model, CAD file, template) for carrying out the work, and that processing them and manufacturing the product will not infringe intellectual property rights or other rights of third parties. The customer shall indemnify the contractor in full against any third-party claims raised in connection with the infringement of such rights. The contractor is entitled to refuse to carry out an order where it has reasonable grounds to suspect that doing so would infringe third-party rights or legal regulations.

Models we design:

Where we design a model to your order, it is a work created to order under Section 61 of Act No. 121/2000 Coll., the Copyright Act. Unless agreed otherwise in the quote, you obtain a licence to use the model for the purpose arising from the contract; the exercise of economic copyright remains with the author. If you need a broader scope of rights (for example an exclusive licence or use beyond the agreed purpose), we will agree it in the quote.

Not every 3D model is a copyrighted work — protection covers only a unique result of creative activity (Section 2 of the Copyright Act). A purely technical or functional part with no creative element does not enjoy copyright protection.

Special provisions for entrepreneurs (B2B)

Entrepreneurs only (B2B) — this part does not apply to consumers.

• The total amount of damages is limited to the price of the specific order. We do not compensate lost profit or indirect or consequential damage.
• The limitation in the preceding paragraph does not apply to harm caused intentionally or through gross negligence, nor to harm to a person's natural rights (Section 2898 of the Civil Code).

This limitation forms part of these terms and conditions, which the entrepreneur reviews before confirming the order — it is therefore always agreed in advance, before any damage arises.

Out-of-court dispute resolution — consumers only (B2C)

The Czech Trade Inspection Authority is competent for the out-of-court resolution of consumer disputes arising from a purchase contract or a contract for work: Česká obchodní inspekce, Ústřední inspektorát – oddělení ADR, Gorazdova 1969/24, 120 00 Praha 2, website: coi.gov.cz.

Supervision of compliance with the Consumer Protection Act is exercised by the Czech Trade Inspection Authority.

Personal data protection

We handle personal data in accordance with our Privacy Policy (see the Privacy Policy page).

Final provisions

These terms are governed by the law of the Czech Republic.

Information we provide to you before the contract is concluded becomes part of the contract (Section 1822 of the Civil Code).

We may update these terms in the future; for a contract already concluded, the wording effective at the time of its conclusion applies. The current version is always available on this page.

If you have any question about these terms, write to us at info@twinlayer3d.cz — we will be happy to explain them.
