    Khalid,

    Can you please report your success with your new CCD camera and laser with David? I see on the David site you are having many issues with this more expensive camera.

    Hi drwhen,
    You are right i am having a little difficulty with the new hardware..but, i think i will resolve the issues very soon... I have already got some good success(60%) and the remaining 40% success is very near

    I think my stepper motor gearbox is non-linear... and, now i believe that this is root of the evil... For plane-less scanning, the laser movement must be very uniform..but my stepper gearbox has jerky at some point..i think the double worm screws have some problems with the wheels and the stepper and gear shaft misalignment may also be the reason...
    I am currently thinking of buying ready made solution from
    Stepper Motors with Planetary Gearboxes
    and trying to purchase following product:
    11YPG202S-LW4-R189 This planetary gearbox comes with Nema11 bipolar stepper motor with 189 reduction ratio...

    It has begun! With the horsepower working on the Kinect right now, I bet a fully commercial high resolution scanner will be available based on this technology in the next year...

    Khalid. Why must you use a cheap web cam? Is there anyway to use a high definition camera and import the pictures instead? My brother has a 22megapixel camera, sure would be nice to use that.

    22Mega pixel... OMG, Too much pixels and no software may able to process the generated mesh of that camera...

    hi, Using Logitech 9000 you can get great details.. for example scanning of 1 Euro coin with all stars in it ... Or, scanning a Housefly with full details of legs hair etc...

    Scanning softwares analyze each frame so for scanning a minute you will get 100's of frames to be analyzed by the software and if each frame is of 22MPixel..then you need super computer to compute.. My honest opinion

    Will davids system export into solid model or some time of file that can be used with a cad program?

    David export in OBJ format..You can convert it into STL or CAD file using other softwares.. Cut3D and some other softwares also takes OBJ files and generate toolpaths...

    OK, 3D scan related down. The first steps are clearly done...

    Mcphill,
    Thats amazing, but still need a long way to go for quality scan.. David recent Structured Light scanning software is high speed with excellent quality.. I have no money to purchase a Projector for the time now so cant show you the results... but its fast...

    Default David Vs NextEngine

    It would be good if someone would put a monetary value on all that time spent tweaking your DIY Davidscanner. Someone put down $3 for glue and setup time. I don't know about you but my time is worth money. I would say my NextEngine took me 30 mins to completely setup, download, install, and calibrate. Thats $10 of my time for 30 minutes. I imagine it took several hours of tweaking to get your Davidscanner running just right.

    So $2995+$23 shipping+$10 setup = $3028

    The subject of scan size vs resolution needs to be addressed as well. Yes you could scan a car with DavidScanner in 8 scans, but your resolution is going to go down. You aren't getting the same resolution scanning at 12 inches as you are at 6 ft. You also mention purchasing a high powered green laser. I would suspect that the NextEngine 3d Scanner could be upgraded with higher power laser diodes fairly easily.

    Finally for scanning large complex objects, like a car, you probably aren't going to have a 3d printer or CNC making a whole complete car in one go.

    So you are modeling it just for looks. If you're modeling just for looks try Autodesk 123D Catch. It uses photogrammetry to capture 3d models from your digital camera pics. Works just fine for "looks". Cost almost nothing.

    Thanks everyone for all the insight.

    I'm new to this forum , but I've spent the past few years with the RepRap community developing open source 3D printers.

    I'm wondering if anyone has experimented with building the automated turntable and tilt axes using 3D printed parts, similar to how RepRap aims at building a 3D printer that can print most of it's components. It's ridiculous how expensive the NE multi-drive is ($1000) for example. Any thoughts on a DIY tilt axis?

    I imagine the hardware would be simple to make. The controls for it would be another thing, though. I imagine there is a controller onboard the tilt axis module that takes in the incoming signals and turns it in to step and direction signals. Without knowing how that works, you will be SOL in making it move properly.
