--- title: "StringArt3D FAQ" canonical: "https://stringart3d.com/faq" markdown: "https://stringart3d.com/faq.md" --- # StringArt3D FAQ StringArt3D is a browser-based tool for turning photos or text into 3D-printable string art. The free version is for personal, non-commercial use. Commercial use of generated patterns, files, and physical prints is allowed with an account-based one-time lifetime Premium license, as long as you also have the rights to the source images or source text you use. Open this page: https://stringart3d.com/faq ## What is StringArt3D? StringArt3D is a browser-based tool that turns photos or text into 3D-printable string art. It generates a printable frame, a string path, a browser preview, and export files for supported FDM printer workflows. ## Can I use StringArt3D output commercially? Commercial use is allowed with a Premium license, not the free license. The free version is for personal, non-commercial use only. Premium is a one-time lifetime license, not a recurring subscription or annual plan. It allows you to sell, offer for sale, use in paid client work, use in a business, or otherwise commercially exploit the string art patterns, generated files, physical prints, and other output you create with StringArt3D, subject to the Terms and your rights to the source images or source text. ## What counts as commercial use? Commercial use means selling physical prints, selling generated files, offering prints or generated output as part of a paid service, using output for a business, or otherwise using StringArt3D output to make money or support a commercial activity. ## Do I need Premium to sell prints or files I make with StringArt3D? Yes. Selling output made with StringArt3D requires a Premium license. The free version is only for personal, non-commercial use. Premium is a one-time lifetime license, not a recurring subscription or annual plan. ## Do you store or transmit the images or text I use for generation? No. The image-to-string-art and text-to-string-art generation workflows run locally in your browser. Uploaded images and entered generation text are not sent to StringArt3D servers, not stored on StringArt3D servers, and not shared by StringArt3D as part of the generation process. Account, payment, entitlement, analytics, and infrastructure data are handled separately as described in the Privacy Policy. ## Who owns the rights to my images, text, and generated output? You retain your rights to the images you upload and the text you enter, subject to any third-party rights that may apply. StringArt3D does not claim ownership of your source images, your source text, or the output you create with the Service. You remain responsible for making sure you have permission to use the source material you provide. ## Can I use client photos, commissioned work, or third-party images? Yes, but only if you have the rights or permission needed for that use. StringArt3D does not verify image ownership for you. If you work with client-supplied photos, memorial portraits, pet portraits, or licensed artwork, you are responsible for ensuring your use is authorized. ## What is the AI image prep tip and prompt? StringArt3D includes an optional AI prep tip with a copyable prompt that helps improve source images before you run them through the generator again. It is meant for muddy, low-contrast, or unclear photos. The workflow is: upload the same photo into an external AI image editor, paste the provided prompt, get back the transformed image, and then upload that transformed version into StringArt3D. This step is optional and is there to improve recognizability, not to replace the generator. ## Which printers does StringArt3D support? StringArt3D currently supports Bambu-native `.gcode.3mf` exports for P2S, P1S, X1 Carbon, A1, A1 mini, H2S, H2C, and H2D; selected dedicated raw G-code exports for a small set of non-Bambu printers; Generic G-code; and a guided More printers flow that uses bundled 0.4 mm FFF printer profiles for profile-derived raw G-code. ## What filament material does it support? StringArt3D currently supports PLA for the printed frame. The broader workflow also uses sewing thread or embroidery floss for the string image itself. ## What nozzle sizes does it support? StringArt3D currently supports `0.4 mm` nozzles. Support for additional nozzle sizes may be added later, but the current printer-facing generation and export path is designed around `0.4 mm`. ## What photos work best? The best photos have one clear subject, a readable face or pet, soft lighting, good contrast, and a calm background. A meaningful phone photo with a clean subject usually works better than a high-resolution image with a cluttered background. ## What does Premium include? Premium is a one-time account-based lifetime license for premium features, not a recurring subscription or annual plan. It currently includes premium shapes, larger print sizes, text-mode export, future premium features, and the commercial-use license for output you create with StringArt3D. ## Is Premium recurring or a one-time payment? No. Premium is a one-time payment for a lifetime license to the current premium features and future premium features. It is not a monthly subscription, not an annual subscription, and not an auto-renewing plan. ## Can you share the STL file? No. StringArt3D is not a normal geometric model that can simply be exported as a generic STL and sliced conventionally. The result depends on custom printer movements, string-specific path behavior, and printer-aware runtime logic, which is why the export pipeline and slicer behavior had to be built specifically for this workflow from scratch. The supported output is the generated printer-ready job, not a standard static STL equivalent. ## Is StringArt3D a finished gift or printing service? No. StringArt3D is a DIY tool. It helps you generate the frame and winding path, but you or your print provider still print the frame and wind the thread. ## Can I sell the StringArt3D app, clone it, or resell access to it? No. Premium commercial use applies to output you create with the Service. It does not allow copying, reselling, sublicensing, scraping, cloning, reverse engineering, or building a competing or substantially similar tool from the Service.
