3d scanning for the marine industry

i am requesting help regarding the purchase of a 3d scanner and/or digitizer for use in small speedboats, sailing yachts etc (you get the size). I am very concerned about spending money on something that will not help me. Does someone know how much accuracy is important, and how much accuracy can i get, when referring to a 33ft (10m appx) speedboat hull? i had arleardy proposals for buying imetric, Konica Minolta and Leica scanners i am not sure though which one i should choose as they work in different ways and they dont give me the appropriate answers as far as large object mesh creation accuracy is concerned. Please note that i already own delcam copycad which from what i read is user friendly and rather quick in completing meshes. i am also in search for a designer (CAM) probably a freelance one. Thank you very much in advance...P Ch.

Are you trying to duplicate an existing design ? ( I guess so) MAN !! that's going to be a ton of $$$$$$$$$$$$$$$$ for anything that size. Car makers scan models all the time, but there's quite a bit of post scan CAD, CFD, etc., work before they're ready to make tooling. I would imagine that the equipment and sofware they use cost millions.

Today (at least here in Newport Beach CA.) boats are designed in 3D CAD, and the forms (bucks) are machined on huge five axis routers.

Another thing to think about is accuracy vs scale. An existing hull is going to have a bunch of geometric errors, even if the form was perfect. These might be raised or lowered areas as much as .100" or more deviant from the mean. The scanner is giong to add "this" error to it's own, and you'll have a bit of a mess to clean up. If you're scanning a CAD/CAM generated form, you'll do better, but why not just model it ?

If you can get it into a dark shop and have a powerful projector then

I use to do 3d digitizing for an automaker back in Detroit. Costs were rather high back in the late 90's but have dropped considerably. Depending on what you want to do there are several options. I would look into

sales guys. I used to deal with the Capture 3D guys out of Novi, MI.

Accuracy varies as well, we were capable of 50 micron tolerances, although a boat hull will require much less. The packages they offer dump out stl files along with others allowing you to cut from their datasets. There are several other packages out there that will let you hone your data files... look into ParaForm, and PolyWorks. I think both are still around.

Hope this helps some.

for all 3D scanning and reverse engineering solutions. 12-year experts in all types of projects including marine, industrial, aerospace, etc. We use all the scanners and all the softwares so we can either do the projects for you or recommend, sell, train, and support you with the most appropriate solutions.

By the way - not likely the GOM system is appropriate for a 33ft hull project. Way to expensive for the accuracy level that you need for the hull. Call us - we have excellent less expensive solutions. And Paraform is long gone! PolyWorks is great, so are Geomagic and RapidForm - the trick is determining which is best for your apps - this is our specialty - call us.
