    Has anyone been involved in trying to convert a lines plan to a plan that could used to make a halfmodel on a 3d printer? It would be such a natural project. you would build from the deck "down' to the keel and if you were building an America's Cup defender like Reliance, you could build a second model, Resolute perhaps.

    By printing the models back to back the platen could share movement time and if the waterlines lined up, you could switch the print media from white to bronze at the same time. It seems to me that 3D printers were invented with halfmodels in mind.:)

    HI TECH 3d printers MAKING TRADITIONAL HALFMODELS

    The traditional way- one ¼" lift at a time and the hi tech way- one 15mil layer at a time. You could even mak it witn ¼" threaded holes in the back to accomodate a couple of brass mounting screws

    Hi Hhbill,
    As most hull shapes are symetric digital modelling is mostly done on one side only. As an example when I am exporting designs from DelftShip to use in Blender I leave "both sides" switched off and take only half the geometry. Then I'll use a mirroring command to fill in the other side when I need to render.

    3D printing is really coming of age. Try shapeways.com or sculpteo.com for production ideas.

    Kind regards
    Paul

    3D printers take many file formats to produce a model. It depends on what software they are running. It is very straightforward. You just upload the file and press "print'.

    HHBILL I have been doing some projects lately where Line drawings were used to create surfaces/meshes for 5 axis milling and printing. It is relatively straight forward if a little intense, in getting the meshes right. So it will come down to how good the operator of the software is.

    Try any school of engineering close to you. Most have software and 3D printers and may take on your project.

    I do not know the file format used by 3D printers but I imagine it will be the same as those used by CNC routers to create 3D models. If so, it is very easy, from water lines create the virtual model that can be used for 3D printer.
    See a sample of what can be done starting with a paper body lines plan.

    The STL file format is very versatile.

    From lines plan to 3D

    Well it would be just a miracle if you could scan a lines plan and a app on your mobile converts it to a dxf file

    You can scan a plan and save it as pdf. A special, existing software, vectorizes and passes it to dwg format and from there, always with the help of man, the lines go into space, you transform them as you like and saves them in DXF format. Part of that process can not be done with a smartphone but can be checked with it.
