3Dsynth is a new online tool that generates G-code directly for vase shapes. It is designed for printing in vase or spiral mode. This eliminates the usual intermediate step of STL export and slicing, which significantly changes the process.
To start with, 3Dsynth offers several basic shapes that can be selected as presets. These include classic vase shapes, cones, cylinders, funnels, hourglasses, bulbous variants, wine glasses, bowls, and dishes. Numerous “effects” can then be applied to these basic shapes. These include Bend, Noise, Twist, Taper, various cap options for the bottom and top, texture variants such as Bump Map or Extrusion Texture, as well as pattern and interference effects such as Glitch or Line Pattern.
A special feature is the “Profile” function. This is a line that describes the 2D outline of the vase’s outer contour. Points can be moved, and hard edges or curves are also possible.
For export, 3Dsynth requires the selection of a machine profile because the result is not available as a model file but as G-code. Tested profiles are available for Prusa i3 MK3S/MK3S+, Prusa MINI, several Creality K2 and Ender 3 variants, Ender 5, CR-10 models, Bambu Lab X1 Carbon and P1S/P1P, Anycubic i3 Mega and Kobra models, and Voron 2.4, among others. Speeds and temperatures can also be adjusted. After export, the G-code file is dragged into a slicing tool and printed directly without reslicing.
3Dsynth is a paid service, but offers a free tier. This includes the basic functions. The paid version costs a one-time fee of 39 euros for lifetime use.
