Problem
Traditional pen plotting requires either expensive dedicated plotters costing $300-$500 or complex DIY setups that demand 15+ manual calibration steps, G-code editing knowledge, and multiple scattered software tools. Existing solutions often lack support for various printer firmwares, making the process frustrating and inaccessible for most 3D printer owners.
Solution
3DPlotter transforms any 3D printer into a professional-grade pen plotter through a streamlined 3-step process: print a pen holder from the STL database, design in the web app, and generate G-code with one click. The platform eliminates manual calibration through a visual wizard, supports all major printer brands including Bambu Lab, Creality, and Prusa, and includes a custom board for any other printer dimensions. Users access a regularly updated STL pen holder database, design gallery, community sharing features, and comprehensive layout tools. The all-in-one web application replaces the traditional workflow of Inkscape, separate converters, and manual G-code editing with a single integrated solution.
Target Audience
Primary users are 3D printer owners, Etsy sellers, design studios, and educators who want to create pen plotter artwork without investing in dedicated plotting hardware. The platform serves both hobbyists and professionals seeking an affordable, accessible alternative to traditional pen plotters.
