General terms and conditions

for business customers · as of September 2026 · This is a translation for convenience. Only the German version is legally binding.

In short: we exclusively produce prototypes and samples for businesses. The parts are intended for development, testing and presentation. They are not intended for series, safety-critical, medical or food-contact applications, and the customer verifies their suitability for the specific use (§ 7).

§ 1 Scope

  1. These terms apply to all contracts for the production of parts by 3D printing between PrintForm (provider details see imprint, the “Contractor”) and the customer (the “Client”).
  2. Our services are aimed exclusively at businesses within the meaning of § 14 BGB, legal entities under public law and special funds under public law. We do not conclude contracts with consumers (§ 13 BGB). The Client confirms its business status when ordering.
  3. Deviating or supplementary terms of the Client do not become part of the contract unless we expressly agree to them in writing.

§ 2 Conclusion of contract

  1. The presentation in the online price calculator is not a binding offer. By clicking “Place binding order”, the Client submits a binding offer.
  2. The automatic email that follows immediately only confirms receipt of the order and does not constitute acceptance.
  3. The contract is concluded when we confirm the order by email after checking the files (order confirmation) or begin production. We may reject orders without giving reasons, in particular if files are not printable or the intended use is evidently outside § 7.
  4. Quotations created with the price calculator (“Quotation as PDF”) are non-binding and valid for 30 days. The prices at the time of ordering apply.
  5. For files whose dimensions and volume are entered by the Client (e.g. STEP), the price shown is provisional. If the verified price differs, we will inform the Client before the order confirmation; the Client may then withdraw the order free of charge.

§ 3 Prices

  1. The prices shown in the price calculator at the time of ordering apply. As a small business according to § 19 UStG we do not charge VAT; the prices are final prices.
  2. Shipping and packaging costs, setup and material setup fees, volume discounts and surcharges for express production are shown separately before ordering.

§ 4 Payment

  1. Payment is made either on invoice by bank transfer or via PayPal (including credit card via PayPal).
  2. Invoices are payable within 14 days of the invoice date without deduction. For payment via PayPal, the amount is to be paid after receipt of the payment link.
  3. In the event of default, the statutory provisions for business transactions apply (§ 288(2) and (5) BGB). We are entitled to request advance payment from new customers or for larger orders.

§ 5 Delivery and transfer of risk

  1. Stated lead times are non-binding guidelines unless expressly agreed in writing as binding. They begin with the order confirmation. A requested delivery date is non-binding unless expressly confirmed in writing.
  2. The risk passes to the Client when the goods are handed over to the shipping company (§ 447 BGB). In case of collection or delivery by us, the risk passes upon handover.
  3. Partial deliveries are permitted insofar as they are reasonable for the Client.

§ 6 Obligations of the Client, print data

  1. The Client is solely responsible for the design, dimensional accuracy, function and suitability of the parts for the intended purpose. We only check the files for printability, not for technical correctness or suitability. Our automatic model check is an aid and does not replace this responsibility.
  2. The Client warrants that it holds all necessary rights to the transmitted data and that production does not infringe any third-party rights (in particular copyrights, patents, trademarks or design rights). The Client indemnifies us against third-party claims arising from such infringements.
  3. We do not produce weapons, weapon parts or other items whose manufacture or possession is unlawful, and may reject or cancel such orders at any time.

§ 7 Prototype nature, properties and tolerances

  1. All parts produced by us are prototypes or samples. They are intended exclusively for development, experimental, testing, visual and presentation purposes. The agreed quality is solely conformity with the transmitted print data within the process-related tolerances (paragraph 4).
  2. Unless expressly agreed otherwise in writing, the parts are not intended or approved for
    • series or permanent use in end products,
    • safety-relevant or load-bearing applications where failure could cause personal injury or significant damage to property (e.g. automotive, aerospace, machine and pressure vessel construction, lifting and securing equipment),
    • medical devices and use on or in the human body,
    • contact with food or drinking water, or toys.
  3. We give no guarantee or assurance of the suitability of the parts for a particular purpose, of load capacity, service life, temperature, UV or chemical resistance, or of certifications and compliance with standards. Material information is based on manufacturer data (guide values measured on test specimens) and does not constitute a description of quality. Before any use, the Client checks on its own responsibility whether the parts are suitable for its purpose. If the Client uses them contrary to paragraphs 1 and 2, it does so at its own risk and indemnifies us against third-party claims to the extent permitted by law.
  4. Due to the process (SLA on a Formlabs Form 4), dimensional deviations (typically ±0.15 mm, depending on size and geometry), warping, visible layer lines, traces of support structures, post-curing effects and slight deviations in colour and surface may occur. These do not constitute a defect.

§ 8 Inspection obligation and warranty claims

  1. The Client must inspect the goods immediately upon receipt and notify us in writing of visible defects within 7 days and of hidden defects immediately upon discovery (§ 377 HGB). Otherwise the goods are deemed approved.
  2. In the case of justified defects, we provide subsequent performance at our discretion by repair or new production. If subsequent performance fails, the Client may reduce the price or withdraw from the contract in accordance with the statutory provisions.
  3. Warranty claims become time-barred 12 months after delivery. This does not apply to claims for damages under § 9 or in the case of intent or fraudulent concealment of a defect.

§ 9 Liability

  1. We are liable without limitation for intent and gross negligence, for injury to life, body or health and under the German Product Liability Act.
  2. In the case of simple negligence, we are only liable for breach of an essential contractual obligation (cardinal obligation) whose fulfilment makes proper performance of the contract possible in the first place and on whose observance the Client may regularly rely. In this case liability is limited to the foreseeable damage typical for the contract, but no more than the order value.
  3. Otherwise liability is excluded, in particular for consequential damage arising from use of the parts outside the prototype purpose described in § 7.

§ 10 Confidentiality and data

  1. We treat all transmitted files and information as strictly confidential, use them exclusively to perform the order and do not pass them on to third parties.
  2. The files are deleted automatically 180 days after completion of the order. All rights to the data remain with the Client.
  3. Further information can be found in our privacy policy.

§ 11 Retention of title

The goods delivered remain our property until all claims arising from the contract have been paid in full.

§ 12 Final provisions

  1. The law of the Federal Republic of Germany applies, excluding the UN Convention on Contracts for the International Sale of Goods (CISG).
  2. If the Client is a merchant, a legal entity under public law or a special fund under public law, the exclusive place of jurisdiction for all disputes arising from the contract is Aachen, Germany.
  3. Should individual provisions be invalid, the validity of the remaining provisions shall not be affected. In case of doubt, the German version of these terms prevails.
