- After creating your drawing, it is importa … After creating your drawing, it is important to make sure that there is a large contrast between the black drawing and the white paper. This will help with scanning and vectorising the image.

- Create your free-hand drawing on paper mak … Create your free-hand drawing on paper making sure to use a black marker pen. This is where the Educator/Youth worker can talk about the ideas behind Design for Manufacturing. When you make a design you need to think about certain elements that will be effected by the manufacturing process. For example: - You will need to think about how your drawing will print out. If some parts of the drawing are not connected, they will print out as separate parts and not together. - You will need to think about time, money and material. How long do you want your print to take? How much material do you have to use? How much will your print cost? The more complex the drawing or the more filled in spaces, the longer it will take to print, the more material it will use and the more expensive it will be. - You will need to think about the limitations of the 3D printer. For example; It is only able to print in one colour Fragility of the print and having to remove it from the printer or raft - therefore considerations should be made as to how thin lines should be made. made as to how thin lines should be made. +
- Depending on your printer and the quality … Depending on your printer and the quality of print you are wanting to reach, make sure to apply the correct settings. This will include adapting the speed, quality and density of the print. Also it can sometimes be best to add a Raft to the print to help with its removal after it has finished, especially if some parts are thin and fragile.cially if some parts are thin and fragile. +

For example, the image, as seen on the screen, is being turned into a simple text file which includes just lines of code that the printer can read. It provides co-ordinates for where the nozzle should move to and where it should turn on and off to lay plastic. it should turn on and off to lay plastic. +

Once cropped, choose the 'Magic Color' filter to make sure there is a good contrast between the drawing and the paper. If any white gaps appear at this point, it may be necessary to edit your drawing and re-do this step to remove these.awing and re-do this step to remove these. +

- Vectorise your image in Inkscape by select … Vectorise your image in Inkscape by selecting it and going to Path > Trace to Bitmap > Remove background > Update > OK This should make a copy of the image above the existing one. Make sure to delete the old image below. Here the Educator could discuss with the participants about what this action is doing and what it means if an image is vectorised. Vectorisation is where a raster image (an image made up of square pixels) is changed to a vectorised image (an image made of geometric objects, such as lines, curves and points, that can be defined mathematically). Through doing this, they can be better read by a computer, are of higher quality and more easily scalable.puter, are of higher quality and more easily scalable. +
