High resolution 3D scan?

PJones · 2016-06-09T03:30:18.000Z

I was wondering if there is someone who is capable of scanning a chrome (highly reflective) hood ornament? I’m looking for a scanner with similar resolution to the creaform 3D handyscan 700 series (0.03 mm to 0.05 mm accuracy). If you would be able to provide a price for the roughly 6 inch cubed hood ornament that would be fantastic. Thanks in advance.

Hi,

It is almost impossible to 3d scan a reflective part. The parts need to be coated with i.e talc power, etc If you in need for a scanner have a look at nextengine 3d scanner, one of the cheapest.

A 3D scan is like making a photocopy and it will have errors and will need cleaning.

Unless you object has a lot of round curvy surfaces it is always better and a lot more precise to take the dimensions and re-design it from scratch.

Reflective surfaces can not be scanned, we have had success by coating plastic objects with corn starch and chromed parts with grey primer that we later remove with acetone. (do this only with metal parts, acetone will dissolve plastic).

Good Luck!

So is it almost impossible or a simple matter of some baby powder? Your post is confusing me.

Have you contacted some local hubs that offer 3d scanning to see if they can help? A lot of hubs do not read the forums. And as pointed out below the item will have to be coated in something non reflective in order to produce a scan which you will want to discuss to ensure it can be easily removed.

Reflective surfaces CAN NOT be scanned, we HAVE HAD SUCCESS by coating plastic objects with corn starch and chromed parts with grey primer that we later remove with acetone. (do this only with metal parts, acetone will dissolve plastic).

We have Artec scanners and we can scan it for 120$/h. It should not take more than one hour.

sorry for confusing you…

Reflection parts are impossible to scan…unless it is treated with a layer of substance that can dull the reflection…like baby power or leak prevention spray…

SOC3D · 2016-06-09T14:49:24.000Z

It’s madness.

You have scanned reflective surfaces by coating them in things. You’ve done the impossible.

It’s impossible to print with a string of ABS plastic, I have had success by heating the plastic in a hot end.

@ Miaviator

You are welcome for the help and advice that we all have given to you.

All the nonsense written by people like you is just a waist of time.

Protoscan3D · 2016-06-09T16:34:45.000Z

Are you being sarcastic?

SOC3D · 2016-06-09T16:46:59.000Z

I am not. If someone asks about scanning a reflective/shiny object and the answer is, “this is impossible”, according to all statistics and research performed that person will over 80% of the time stop reading.

Not one, but two, people responded that reflective objects cannot be scanned. This we all know is complete bunk. The guys making titanium parts for F18 jets 3D scan the parts all day long in order to ensure they are within some ridiculous .001% tolerance. They simply coat the reflective part. (With what I am assuming is $10,000 baby powder or gray primer). It is therefore entirely POSSIBLE and in no way IMPOSSIBLE to scan reflective parts as is later stated by both responders. I take issue with false information being continuously posted to people.

My analogy is very accurate. It is quite impossible to print 3D objects with a roll of 1.75mm diameter ABS filament. I however do so every day by heating the plastic in a hotend. As a general rule, the impossibility is not discussed as the use of a hotend is COMMON PRACTICE and COMMON SENSE. The exact same rule should now apply to 3D scanning reflective objects.

As you would not tell a customer or forum poster:

“it is impossible to print with ABS though I have had success doing so using a hotend”

you should not tell a customer or forum poster:

“it is impossible to scan a reflective object though I have had success using powder or primer.”

I simply take offense to the whole approach which seems to imply you are better than everyone else?

It – is, has, will be – quite – possible, common place, easy – to scan reflective objects. Any information to the contrary is akin to things like the world being flat or printing with ABS being impossible.

@Matterthings Thanks! I appreciate the compliments and advice.

Protoscan3D · 2016-06-09T17:14:50.000Z

Soooo what you’re trying to say is that the guys who 3D scan F18 all day long spend $10,000 on substance to “COAT” the parts first so they can scan it? why coat it if they can scan reflective parts? … You’re confusing me…

Also $10,000 for baby power is a bit daft don’t you think…

Well I want to thank everyone for their comments and help so far. I just want to mention that I do know its not easy to have a highly reflective part scanned and I was sure I probably wouldn’t be able to without having some type of coating on the object. The reason why I asked if someone was able to scan a reflective part was because a buddy of mine who works as a civil engineer knew of a company called creaform who specialize in high end 3d scanners. Apparently they produce a scanner called the handyscan 700 series which my friend mentioned could be used on reflective parts. I just reached out to creaform by e-mail and they responded mentioning that the handyscan 700 series is not the best option and instead the creaform MetraScan was guaranteed to scan highly reflective surfaces such as chrome in high detail (0.064 mm according to: MetraSCAN 3D | Handheld [Optical CMM 3D Laser Scanner] by Creaform). Apparently the MetraScan was just released in April of this year to satisfy the need for scanning reflective parts like those which are chrome plated. Anyways I figured it was a long shot to see if I could find someone with a high end scanner which could do reflective parts as well as high resolution scans for maximum detail. I encourage those who have not looked into the creaform handyscan 700 series (- YouTube) to see why I posted what seems to be a ridiculous question about high detail and reflective part scans. I saw this video and I was astonished so I figured there must be someone out there with one of these looking to provide scanning services so I figured why not ask.

What kind of Artec scanner are your sporting for your prints? Is it the artec carmine,eva or spyder?

PJones · 2016-06-09T19:57:54.000Z

Yeah I actually spoke to a maker space which have 3d scanners on hand (the makerbot scanner to be exact) and they mentioned coating the object in baby powder to get a scan completed but mentioned it wouldnt be very high in detail though. Since I have no skills in 3D model design and editing I figured I would look to see if there was someone on 3D hubs which might potentially have a scanner in the professional domain. Maybe I am crazy and should just get it designed If I want such accuracy. I figured I would try and see if there was someone out there that may have a professional grade scanner who may be interested in scanning a reflective hood ornament.

We have Eva and Spider.
