Designing things to make
The simplest scenario: converting a simple 2D image into printable object
Preparation
This short guide assumes you are running a free software *nix operation system and free software tools only. It will probably work on Mac OS, and you might even get lucky on a Windows system.
In addition to your raster image, you will need the following software tools:
- inkscape vector drawing program
- openscad 3d cad modeller
- skeinforge 3d model slicer
- pronterface reprap printer graphical interface
HINT: If you want to follow the instructions below in English even though your language environment is different, you can force a program to start in English. With inkscape for example, open a terminal and type:
LANG=C inkscape
Raster to vector image conversion
- Start inkscape.
- "File" -> "Open". Open the bitmap image you want to convert. When asked if you want to embed or link the image, choose "embed".
- Select the bitmap image by clicking it.
- "Path" -> "Trace bitmap". Fiddle with the options until you get things approximately right.

- Move the vector image overlay you just created out of the way a little.
- Select the original bitmap image and delete it.
- Move the vector image overlay back in place.
- It's only the object itself we are after, so... Delete the edge points of the image.
Straight line segments beteen vector nodes will export cleanly, curved ones will not.
- Select the nodes that belong to curved lines (either drag or CTRL-click). Click "Insert new nodes into selected segments." multiple times until enough straight line segments more or less follow the curved line.
- "File" -> "Save as". Set the file type to save as to
Desktop Cutting Plotter (R13) (*.dxf)
.
More
If you are designing things to be made in RepRap, Ed's guide on to how to design for FFF above may be useful. It's written for the Stratasys Dimension proprietary RP machine, but almost all of what it says is relevant to RepRap too. One difference: ignore the section on adjusting hole diameters to get them to come out right. On RepRap, if you specify a 3mm hole, it comes out as 3mm...
Rather than design things completely from scratch, you might save a bit of time by starting from something in the Available Files and tweaking it to fit your needs.
