pandelume I completely understand what your saying now that i looked into it deeper, i watched a video on YouTube (tested was who released it i think) and they showed how the point cloud was and how it sucked lol but i think your have a good idea with scanning something and then taking it into CAD and "fixing" it cuz i would have the part and its dimensions at hand and like you said it would be somewhat of a pain but still better than starting from scratch. really my shop is just a toy shop for the grown kid (me) :D and i happen to have a great wife who's supportive (even better) lol now i have heard some better things about the Sense scanner by cubify and even tho its for larger objects i think im going to buy it and see what happens and since my son don't use his Kinect from his Xbox dear old dad may have to borrow it and give it a shot with this software you mentioned.. awesome stuff for sure and thanks for all the help!

Sorry if i come off pissy or something but 16 years of the Navy does that and being in pain pretty much 24/7 sucks ass! I'm going in for surgery here this coming month with hope to releave some of this pain.. :(

Hello Big D

Are you still looking for high quality small part 3D scanning? I have a NextEngine scanner. It's perfect for small parts. I would love to chat with you (or anyone else) about trading scanning for metal work/ casting.

I have started using Autodesk Fusion 360 for CAD CAM and I highly recommend it. My general workflow is to scan using the NextEngine software, clean up the point cloud and export as .OBJ. Then import into Fusion 360 and re-work the dense OBJ mesh into a optimized CAD part.

I use my scanner often, and purchased it in 2009, it's a workhorse.

For small parts, or anything you wish to scan with any degree of accuracy, I would stay away from the Kinect, Matter and Form, MakerBot Digitizer. Just my opinion! They are great, but I don't think they are going to be able to capture the detail that you need for small complex parts.

Some things to consider- the NextEngine is an optical device, so getting good scans means you must prepare parts. Shiny surfaces can be a dealbreaker. Sometimes it's impossible to "see" complex undercuts and sidecuts or interior cavities. To insure good scans, sometimes it is necessary to use a "sacrificial" part- a duplicate of the part you wish to scan. That way, you can disassemble the part and scan it in sections. You can paint the part or coat it with a matte surface finish, making the scan more accurate.

Hope to hear from you!

Took a look at the NextEngine scanner. Impressive. http://www.nextengine.com/

From their comparison of scanner capabilities if I were to consider a scanner it would have to be the NextEngine. However, at $3000 you really would have to scan a lot to make it worthwhile. Maybe a service business opportunity.

It is actually $7000 with the good platter and the software that helps make parametric CAD models.

You can download a free-for-personal-use version and I believe it only requires a microsoft kinect (or equivalent hardware). I'm not sure it'll suit your needs, but for that price it's probably worth a try.

Going back to how you want to use the scans, I'm not sure it'll work out. I basically want the same thing you do, but from what I can tell this is the situation: professional scanners (i.e. create dimensionally accurate scans and are reliable) are too expensive, and hobby scanners - which mostly seem to be image processing based - are either not all that accurate or don't reliably give good results. On top of that, editing the scans afterwards is something of a dark art - at least if you want to accurately represent a real object. Mainly because the scan is just a mesh, so editing any given feature is not easy using solid-based CAD software. The best I've been able to do along those lines has been to import the scan and convert it to a solid then add the required features back in. Because the scan isn't necessarily all that accurate, this usually requires having the original part in front of you so you can measure it as you model the critical features. It's definitely better than having to model complex geometries from scratch, but it's still kind of a pain.

Having said all that, if your tolerances are such that you can scan and print without editing then the headache goes away. I'd suppose the only way to know that is to try a given scanner and see how close you get.
First off sorry for not getting back sooner I have been out of town..

Now that i have gotten my feet wet with the 3D printing/scanning STUFF I agree 100% and unless you drop 8-12 grand on a professional scanner the "hobby" scanners just don't do what I had set in my mind they did with that said, I dropped the chunk of change and got a "professional" HDI 120 scanner and I bought a Sense hand held scanner and the difference's are night and day as they should be..

The HDI does a very good job with detail and even hollowed out pieces, Its very flexible in size's it can scan the specs of the HDI don't do it justice as it undercuts it big time its just how you go about scanning that makes the difference now it does have its limits as far as how large you can go of course but I have scanned a penny with great results and all the detail you see on the penny ( I didn't print it I was simply playing with it) Here is where I got the HDI 120 series scanner, and they are great people--http://www.lmi3d.com/3d-modeling-solutions

As for the Sense hand held scanner well it has its place and does a good job as long as you move very slow as to not let it lose track of where its at or your starting over. I found it doesn't see hollow objects well at all but when I tapped it to the back of my MacBook Pro and walked around my son who was sitting in a chair and did this at different angles of attack it worked very well and like most of the "hobby" scanners it doesn't like a glossy finish on anything but it is in full color. The HDI doesn't seem to care what the finish is on an object it scans in color and rather fast with little to no holes to be fixed.. that's my findings and I hope it this helps some but I would recommend the Sense scanner for the money as long as its used right and try different angles of attack and a trick I found (not sure if anyone else has done it yet) but if you have a wife or girlfriend ask her for the powder she puts on her face that's skin tone (not sure what its called) and um don't tell her your going to use it on what ever it may be lol but it dulls a glossy finish enough that the scanner does a good job of picking up the detail and then comes off pretty easy too..

Ps. my wife just told me that there is a liquid woman also use on their face and I'm not sure that would be wise to use as you may not get it back off.. I'm not sure but maybe if someone has a wife/girlfriend with this kind they can try it and fill us in..?? oh my wife just said its called "foundation"..

Well, that escalated quickly.. :shock:

I just picked up a Davidscan SLS2 last week, still in the box but I should be ready to jump in this weekend, will report my experience if anyone is interested. I waffled a lot between that and a couple other options..hopefully I chose wisely.

Depending on the price you pay -it's called smoothing powder, finishing powder, shine-reducing powder or sometimes just face powder - buy the cheapest matte version you can find at Walmart or Target. (To the great chagrin of several hollywood bimbos, some of the more expensive ones actually have a "built-in-glow" effect that can get magnified by a camera flash and cause a white reflection. Can't imagine that would be good for a scan.)

(And if your wife finds out you are using her good stuff on a part bud, you'd better haul ass. The price on that sh*t is obscene.) :lol:

If you want to dull a glossy finish....I'd try hairspray. Think of what it does to the glass.

Lol I'm glad you know about makeup cuz I sure don't :) haha...

I tried hairspray and many other things and the only thing that seemed to work well was the "face powder" :) the hairspray did leave a matte finish but with glossy spots and those spots ended up being holes some to bad to fix. Also it doesn't come off all that easy as the power does and I used a soft bristled paint brush and applied it as my wife's is a powder..

The HDI scanner will set you back 8-10k.. Yea it hurts and unless your using as a money making tool don't do it but if your after very nice scans that are deep in detail and scans pretty fast then I guess you have to take out a second mortgage on the home lol

A bunch of my work I can't post online anywhere or it would be the last time I do anymore of it ;)

But I can fill you guys in on a build I'm doing but I'll do that under another thread and after I get all the bits and pieces :D
