3d scanner at "low" cost

[anto_95]

Sorry guys but I didn't find any recent information about it.
My dilemma is this, I would need a scanner to get "hopely" and faithfully high objects such as mechanical parts of cars and motorcycles for later reproduction and manipulation on cad
I saw nextengine (a little expensive for my pockets)
and david laser scanner a little more affordable http://www.nextengine.com/http://www.illustrami.com/it/pacchetti-scanner-3d-completi-david-laserscanner/20-david-laserscanner-starter-kit-sls-1-v2.htmlAre they accurate enough? difficult to use?
I never used one.. always hand-drawn.. that you can advise me?

small info.
I look for a 3d scanner with
what to do scans of mechanical parts and get the dwg...
one of the products listed above lends itself to my purpose according to you?

the scanner is not enough, you must also model. Scanning only serves to measure.

info: if I had a 3d scanner
and put us under a particular mechanic.
Does this pull me out the file in dwg or in some other format?

you have a file in stl, but without software to manage those formats and clouds of points to get a mathematical surface you don't make (almost) anything. certainly does not export to dwg.

I would be curious to know how many wateristano these 3d scanners bred by the low cost and then, easily obtained the cloud of points, collide hard with all the reverse work that is after us, including software. of the series spend 1,500 € of scanners then need 15 or 20,000 for a software that can effectively manage a few million points to be transformed into iges surfaces or in step.

Thank you very much.
I was wondering why we are evaluating the purchase of a new measuring instrument in the company.
we are evaluating a three-dimensional, automatic or manual machine with tastatator.
or always a three-dimensional machine, but with laser beam detection of about 100-250 mm,
or I thought about the scanner3d.
But I do not know anything about the operation.

 

[anto_95]

no surely the scanners mentioned above do not work well for what interests us, i.e. at least I need absolute precision and these if it's okay have a tenth of error! the scanner is a great purchase but you have to estimate at least 15/20 millini for something serious. Unfortunately now I don't have the references of the dealers I had contacted, but if you're interested, I find them.

 

[Fulvio Romano]

What do you mean by "absolute precision"?

 

[maxopus]

and you can't even do it with 15-20 "millini" unless you go on the road.
a hybrid professional measuring instrument (with laser and mechanical probe) starts from 40,000 euros up ... software excluded.
instruments of 10-15 thousand euros have a decidedly different precision.

the mythological error zero. but no one has yet found out where he is

 

[pinkisback]

Unfortunately I have seen the prices:-(
Thank you.

for this there are the companies of service. if the tool you have to use it every day you buy it, otherwise you turn to someone who has it and who provides the service.

 

[pinkisback]

I know.
but in the company the policy is to create a metrological room slowly.
bought profile projector, altimeter and feedback plan.
short order a usb microscope (stupid) x check the inserts,
and the prox step will be the 3d measuring machine
even if it costs like a kidney and two eyes:-(

with service we make rx and welding magnetiscopies,
but you should buy the equipment. with 25,000€ take everything.
with the service bleed you:-(

hello max, can you tell me any of these hybrid tools?
in companies we are evaluating the purchase of a 3d scanner, both for measurements and to have the cloud of points.
we need absolute precision, because the pieces to measure/scans are small enough (5-15 mm) and we should be able to detect dimensions of cents or tenths of millimeter.
we have evaluated some tools that measure by contact, but it is not good for our needs. . .

I tried david laserscanner, given the irresistible cost of the necessary hardware, and yes, it's okay for hobbistic use, nothing even remotely comparable to something professional. at least with regard to mechanics. without counting the lack of a tool that allows to reconstruct the surfaces.

I have seen on the web the product, but it is not what it does for me, in fact I need more a tool of vision/measure, and the prices are in the order of tens of thousands of euros.. .

Hi.

relative to the non-contact scanning of small mechanical and/or artistic parts, from 10 mm up to 80 mm I turn you a series of examples that give you some indication of the details we manage with our 3d measuring system.
If you think you might be interested, let me know here on the forum that I give you some technical details. For example, the gear is about 200 mm in diameter

 

[tecnico_plast]

Interesting, are you a dealer?
mainly the pieces on which we should work are of the order of about 20 mm, but it could also serve for larger pieces.
Obviously it is essential to measure also on the z axis.

I heard about measuring the tenth or the cent of a millimeter.
for the centimeter of millimeter, I do not weigh superficiality if I say that the optical instrument (in light structured to fringe or laser) does not exist on the market, as such instruments have an error of at least +/- 2 cents of millimeter.
as a measuring instrument must have a precision of at least one order of magnitude greater than the measure to be acquired (to measure the millimeter, the instrument must be accurate to 1 tenth of a millimeter) ... we are not.
for the tenth of millimeter in theory we are not even, keeping in mind always the theoretical error mentioned above, in reality we speak of at least +/- 3 or 4 cents of error.
for which a portable optical acquisition tool can be used to measure dimensions of at least 4 tenths of millimeter, if accuracy is a determining factor in measurement.
