    Which control software for 3D laser printing?

    Hi,

    I'm familiar with electronics, machines, mechanics and even with laser scanner systems and I plan to build an own 3D laser printer (yes, I know it is dangerous but as said, I'm not a newbie in this area). So from hardware point of view I can do (nearly everything) for my own but I have some problems finding a suitable software. So: what software can be used to support laser marking systems for laser-based 3D printing? It should support not only the laser scanner but also external equipment like motors. Any recommendations? How about this one here: https://replisls3d.com - did anybody already try this?

    Cheers

    Mike

    I don't understand what laser 3d printing is. Can you explain a little further.

      It is 3D printing but without the use of a plastics extruder. A 3D model is imported into a software, then sliced into layers (same as for conventional 3D printing). Next in build space a thin layer of a suitable material (typically a powder but can be a liquid too) is applied where the laser marks the data of the first layer of the sliced model. This material is melted to one piece by the laser. Then the build space's Z-position is moved slightly, the next layer or material is applied, the next slice is marked and so on. So quite similar to conventional 3D printing the model is built up layer by layer just by melting the material to one big piece. Finally you have to dig the built up model out of your material and can reuse the remaining powder for the next model.

      The disadvantage: because of the laser and scanhead this method is more expensive. The advantage: the result is much more exact sine such a laser has a spotsize of some microns, so when you have the resulting 3D model in your hands, you typically can't see that it was 3D "printed".

        Hi Mike
        Dont know how much you have found yourself on www but found this from a fast search: http://reprap.org/wiki/OpenSLS or http://directmachining.com . One open source and one commercial
        But search for open source sls software... god luck!

          Hello perolalars,

          yes, these are the ones which I found too - and which I dropped. OpenSLS is too limited and too complicated and DirectMachining way too expensive (they ask for a five-digit number for their software which seems to be close to fradulent for me). So I hoped somebody has already tried this RepliSLS3D thingy, it is way cheaper than DirectMachining but I have not yet done too much with it...

          Cheers
