Disclaimer and terms of use

1. What this site provides, and what it does not

Vuolti provides parametric geometry generators. They calculate a mesh from the values you enter and hand you an STL file. That is the entire scope of the service.

We provide no design service, no engineering review, no material consultancy and no quality assurance. Nothing on this site is a technical approval, a certification, a fitness statement or advice of any kind. Every output is a draft that you are responsible for checking.

All content on this site — texts, figures, illustrations, notes, warnings and the generated geometry itself — is provided for general information purposes, without any warranty as to correctness, completeness, currency or fitness for a particular purpose.

2. No guarantee that a part fits

A generated part is built from the numbers you type in. If those numbers are wrong, measured imprecisely, taken at the wrong spot, or do not account for the tolerances of the object the part has to fit, the result will not fit. We cannot verify your measurements and we do not attempt to.

Even with correct input, a printed part may not fit. Printers over- and under-extrude, materials shrink and warp as they cool, elephant foot widens the first layers, holes print undersized, and every filament and resin behaves differently. Deviations of several tenths of a millimetre are normal and entirely outside our influence.

Clearances, plug depths and fit tolerances offered by the configurators are starting values based on common printers. They are not a promise. Always print a small test piece before committing to a large part.

3. Your printer, your slicer, your settings

Layer height, wall count, infill, print and bed temperature, cooling, print speed, flow and shrinkage compensation, bed adhesion, supports, orientation, brim or raft, drying of the material, nozzle diameter and the calibration of your machine all determine the outcome, and all of them are set by you.

The support notes shown by a configurator are guidance for a typical FDM printer. Whether a specific part on your machine needs support, and where, is yours to judge and to configure in your slicer.

We accept no liability for failed prints, spaghetti, layer shifts, warping, detached parts, clogged nozzles, damaged build plates, wasted filament or resin, wasted electricity or wasted time.

Never leave a 3D printer running unattended. Printers are heating appliances and can catch fire. Responsibility for the safe operation of your equipment lies entirely with you.

4. Materials, strength and durability

We make no statement about the mechanical strength, load capacity, temperature resistance, UV stability, chemical resistance, ageing behaviour, water tightness or dishwasher safety of anything you print. These properties depend on the material, the printing parameters and the load case — none of which we know.

Printed parts are not food safe. Layer lines harbour bacteria, and neither the material nor the process is certified for contact with food, drink, cosmetics or medication. If you use a part in that way, you do so entirely at your own risk.

Printed plastic parts age. They become brittle under UV light, soften in heat, creep under sustained load and can fail without warning.

5. Applications you must not use these parts for

Do not use generated parts where a failure could injure someone or cause significant damage. This includes in particular, and is not limited to:

• load-bearing or structural applications of any kind
• anything overhead, suspended, or that could fall on a person
• medical, dental, orthopaedic or laboratory use
• toys, childcare articles or anything within reach of small children
• protective equipment of any kind
• electrical installations, live parts, enclosures for mains voltage
• vehicles, bicycles, aircraft, drones, boats and their components
• pressure vessels, gas or fuel-carrying parts
• anything near open flames, heaters, cookers or other heat sources
• lifting, climbing, safety or rescue equipment

If you nevertheless use a part in such an application, you do so on your own responsibility and at your own risk, and you accept full liability for the consequences.

6. The software itself

The configurators are provided as they are, without any warranty. We do not warrant that they are free of errors, that they will be available, that they will run in your browser, that the geometry they produce is valid or watertight, or that an exported file will open in your slicer.

A geometry generator can produce a defective, self-intersecting or non-manifold mesh under input combinations we have not anticipated. Inspect every file in your slicer before printing.

Nothing is stored for you. Your configuration lives only in the open browser tab. Closing the tab, reloading the page, a crash or a browser update will lose it. We accept no liability for lost work.

We may change, restrict or discontinue functions, the free scope or the entire service at any time, without notice and without any entitlement arising from that.

7. Third-party rights are your responsibility

Whether a part you generate infringes a patent, a registered design, a trade mark, a copyright or any other right of a third party is for you to establish. This applies particularly to replacement parts and to anything that reproduces or replaces a commercial product.

We do not check what you build and we accept no liability for any infringement of third-party rights arising from your use of the generated geometry.

8. Permitted use

Under this free usage, the generated files and the parts printed from them are for your own private, non-commercial use. They may not be sold, licensed, published, shared or otherwise commercially exploited under this free usage.

A separate Vuolti solution for commercial use is planned. Commercial rights only arise once Vuolti explicitly offers such a licence and it has been validly acquired for the specific use.

The configurators themselves, their source code, their design and this website may not be copied, re-hosted, decompiled, redistributed or presented as your own product.

9. External links

Our pages may link to external websites over whose content we have no influence. Responsibility for that content lies with the respective operators. At the time of linking, no infringements were apparent.

10. Indemnity

You indemnify us against all claims that third parties raise against us as a result of your use of the generated geometry, of the parts you print from it, or of your breach of these terms — including reasonable legal costs.

11. Limitation of liability

To the extent permitted by law, all liability for damages arising from the use of this website, the configurators or the generated geometry is excluded. This applies in particular to material damage, financial loss, loss of profit, loss of data, business interruption and consequential damage of any kind, however caused.

This exclusion does not apply to damages arising from intent or gross negligence, to injury to life, body or health, or to liability that cannot be excluded under mandatory law — in particular under product liability legislation and mandatory consumer protection law. Nothing in this disclaimer is intended to limit rights that cannot lawfully be limited.

12. Severability

Should any provision of this disclaimer be or become invalid, the validity of the remaining provisions is unaffected. The invalid provision is to be replaced by one that comes closest to its economic purpose within what the law permits.
