Not legal advice
This guide is a practical starting point for 3D printing service businesses. Laws vary by jurisdiction. The example wording below is illustrative — have a solicitor or lawyer review your terms before you publish them.
The short answer
Written terms set expectations before a problem happens. They tell your customer what you will and won’t do, what counts as acceptable quality, when you’ll refund or reprint, and who owns the uploaded file. Without them, every dispute is your word against theirs. You don’t need a 20-page legal document — a clear, plain-English page covering the nine clauses below is enough for most services starting out.
Why you need T&Cs
Three real scenarios that written terms prevent:
- Customer claims the print is “wrong.” But it matches their STL exactly — layer lines, tolerances and all. Without a clause on quality expectations, you’re arguing about what “good” means.
- Chargeback dispute. Customer files a payment reversal claiming non-delivery or defect. Without a written refund policy linked at checkout, the payment provider sides with the buyer by default.
- Customer sends a trademarked model. You print it, they sell it, the rights holder comes after you. Without an IP clause, you have no documented indemnity.
What to cover: clause by clause
Below is a practical checklist with example wording for each clause. Adapt the specifics (formats, tolerances, timelines) to your service.
1. Scope of service
Define what you do — and what you don’t.
“We produce physical parts from 3D model files supplied by the customer. We do not provide design, engineering or modelling services. If a file cannot be printed as supplied, we will notify the customer before proceeding.”
2. File requirements
State which formats you accept and basic geometry requirements so you can reject unprintable files without argument.
“We accept STL, 3MF, STEP and OBJ files. Models must be manifold (watertight) with a minimum wall thickness of 0.8 mm. Files that do not meet these requirements may be rejected or require additional preparation at the customer’s cost.”
For more on formats: STL vs 3MF vs STEP vs OBJ.
3. Turnaround & delays
Set expectations as estimates, not guarantees, and cover machine breakdown.
“Standard turnaround is 3–7 business days from payment. This is an estimate, not a guarantee. Delays caused by machine failure, material shortages or force majeure do not entitle the customer to a refund, though we will communicate delays promptly.”
4. Pricing & payment
Make clear that prices are calculated from geometry and may change if the file changes.
“Prices are calculated based on the uploaded model’s weight, dimensions and estimated print time. A quote is valid for 14 days. Payment is required in full before production begins. If a file is revised after quoting, a new price will be issued.”

5. Tolerances & quality
Set realistic expectations for FDM (or your process) so “it has layer lines” is never a surprise.
“Parts are produced via FDM (fused deposition modelling). Dimensional accuracy is ±0.3 mm typical. Visible layer lines, minor stringing artifacts and support-contact marks are inherent to the process and do not constitute a defect.”
6. Refunds & reprints
Be specific about when you will and won’t reprint.
“We will reprint or refund at our discretion if a part fails due to our error or a machine malfunction. We will not reprint if the customer’s file was defective (non-manifold, incorrect dimensions) or if the customer is dissatisfied with inherent process characteristics described above.”
7. Intellectual property
Protect yourself from printing IP you don’t own.
“By submitting a file, the customer warrants they hold the rights (or appropriate licence) to reproduce the design. We do not review files for IP infringement and accept no liability for claims arising from third-party intellectual property. We will not share, redistribute or use customer files for any purpose other than fulfilling the order.”
8. File storage & privacy
Especially important if you serve EU customers (GDPR).
“Uploaded files are stored securely for up to 90 days after order completion to facilitate reprints or support queries. After this period files are permanently deleted. Customers may request earlier deletion by contacting us. We do not sell or share customer data with third parties.”
9. Liability limitation
Cap your exposure.
“Our total liability for any claim arising from an order is limited to the amount paid for that order. We are not liable for indirect, incidental or consequential damages, including but not limited to loss of profit, data or business opportunity.”
Shortcuts: generating your T&Cs
You don’t have to write every word from scratch. Three approaches, from cheapest to most robust:
- T&C generators (Termly, TermsFeed, Shopify’s free policy generator) — checkbox-driven, produces generic e-commerce terms. Good as a base layer, but usually missing 3D-printing-specific clauses like tolerances, file requirements and IP on uploaded models. You’ll need to add those manually.
- AI (ChatGPT, Claude, etc.) — paste the clause checklist from this guide as a prompt, feed it your business details (turnaround, formats, refund policy) and ask it to draft terms. Free, fast, and surprisingly decent for a first draft. Risk: AI can confidently produce wording that sounds legal but isn’t enforceable in your jurisdiction. Treat the output as a draft, not a finished document.
- Lawyer review (recommended final step) — whether you hand-wrote, generated or AI-drafted your terms, a one-time legal review (typically €200–500 / $200–500 for a simple set of T&Cs) catches jurisdiction-specific gaps. Worth it once you’re doing regular volume.
The progression matches your growth: a hobbyist selling 5 prints a month can AI-draft and accept the risk; someone doing €2k/month in orders should get a lawyer pass.
Where to put your T&Cs
Make them findable and hard to miss:
- Create a dedicated page on your Shopify store (e.g.
/pages/terms). - Link it in your site footer, checkout page and order confirmation email.
- If your upload widget supports it, add a “By uploading you agree to our Terms” notice.
Your terms, enforced by your workflow
Filaquote enforces file requirements (format, size limits) and calculates price from real geometry automatically — so clauses like “price based on model analysis” and “files must be manifold” are backed by the actual workflow your customers experience.

Do I need T&Cs for a small 3D printing side-hustle?
Yes. Even a one-person operation benefits from written terms. They set expectations on turnaround, quality tolerances and refunds before a dispute happens — not after. A simple one-page document is enough to start; expand it as your service grows.
Can I copy another 3D printing service’s terms?
You can use them as inspiration for which clauses to cover, but copying verbatim is risky: their terms may reference services you don’t offer, jurisdictions that don’t apply to you, or language that isn’t enforceable where you operate. Write your own from a checklist (like this guide), then have a lawyer review.
Should I require customers to agree before ordering?
Ideally yes — a checkbox or “by placing an order you agree to our terms” notice at checkout makes the agreement explicit and harder to dispute later. On Shopify you can add a terms link to your checkout page. At minimum, link your terms prominently in your site footer and order confirmation emails.
