Terms of use

Last updated: October 2026. In case of discrepancy, the French version prevails.

1. Introduction

The neoslice-ai.com website and the neoSlice software are published and maintained by Emmanuel Percheron, an independent developer based in Switzerland, acting in a personal capacity.

By accessing the Website or downloading the Software, you accept these Terms of use (the "Terms") without reservation. If you do not accept them, you must immediately stop using the Website and the Software.

2. Description of the service

neoSlice is software that helps you configure 3D prints, intended for the compatible 3D printers listed on the Website (Bambu Lab, Creality, Prusa, Anycubic and other brands), through one of the 9 supported slicers (including Bambu Studio, OrcaSlicer and PrusaSlicer). It analyzes 3MF, STL and OBJ files and generates print configurations that can be exported to your slicer. The base application is free. Some advanced features, including AI photo diagnosis and the Pro Workshop, are part of the paid neoSlice Pro offer (see section 4a). The Software is provided "as is", is continuously improved and may contain errors. The Pro offer also includes neoForge, a 3D modeling module provided as a separate program, downloaded on demand from the publisher's distribution servers the first time it is used.

3. Access and availability

Access to the Website and the Software is provided free of charge, with no guarantee of permanent availability. The publisher reserves the right, at any time and without notice, to:

• modify, suspend or interrupt access to the Website or the Software;
• change the features of the Software;
• stop distributing the Software.

No compensation may be claimed on these grounds.

4. License to use

Use of the Software is granted on a personal, non-exclusive, non-transferable and revocable basis. It is strictly prohibited to:

• resell, rent or sublicense the Software;
• modify, decompile or disassemble the Software;
• distribute the Software through channels other than those officially designated by the publisher;
• remove or alter the intellectual property notices in the Software.

Professional use: you may use the Software, in its free version as well as its Pro version, for your own activity, including professional activity: printing parts for your customers, issuing quotes and invoices. You may sell the parts you print, subject to the rights of the authors of the models you import. What remains prohibited is exploiting the Software itself: reselling it, renting it, offering it as a service to third parties or sharing a license key.

4a. neoSlice Pro, paid offer

neoSlice Pro unlocks advanced features (neoGen, neoForge, the Oen assistant, unlimited AI photo diagnosis, multicolor export and the Pro Workshop) through a one-time payment, with no subscription. The applicable price is shown on the Website and on the payment page. Payments are processed by Gumroad (gumroad.com), which acts as the official reseller (Merchant of Record) and handles invoicing and applicable taxes. The publisher has no access to any banking data.

The purchase gives you a personal, non-transferable license key, which can be activated on a maximum of three devices. Sharing, reselling or publishing a license key is strictly prohibited. To move a license to a new device beyond these three, contact the publisher through the Website's form.

Refunds: a refund may be requested within 14 days of purchase, through the contact form on the Website.

5. Limitation of liability

• the suitability of the settings for a specific use.

The user remains solely responsible for the settings they choose to apply and for the results obtained.

5.2 Damages

Under no circumstances shall the publisher be liable for:

AI photo diagnosis provides automated identification of print defects and suggested corrections, for guidance only. The publisher guarantees neither the accuracy of the diagnosis nor the relevance of the suggested corrections. The user remains solely responsible for the settings they choose to apply.

6. Personal data

6.1 Browsing
