What happens when you let a knife knut play with a $70k laser scanner...

[SpyderPhreak]

He scans his current EDC!!! :cool: :p A Maxamet PM2 in this case. :D


If anyone wonders why/how the counterfeits can come so close, well this is just one of many reasons. This particular portable laser scanner is good to just 0.002”!!! That’s almost within machine tolerance of many CNC’s.

I didn’t spray my knife down with the powder “developer” spray, so the reflective metal surfaces didn’t come out as nearly as good as they could have if I had, but they’re still pretty darn good all things considered. This laser scan consists of nearly 100,000 small triangles!

Hope you enjoyed! Pretty cool tech, but kind of scary at the same time. :spyder:

Nice! I need to scan one of my Mules so that I can CNC accurate handles for it. I have lots of design ideas, but need a CAD model to work off of to get the holes and outline (and their relative positions) just right. Even a 2D outline with hole placements would work, as I dunt need any thickness info for what I'm doing. So far I've done all my Mules by hand, but some designs I have in mind would need a CNC to accomplish. Maybe I'll look into having somebody scan one for me.

That's terrific technology, i could have a field day with about 8 hours and unrestricted access to one of these.

Pic of the machine?? Too cool

It’s called a Creaform Handyscan 700.

Neat scan!
awesome machine!
i would like to own one :eek: :cool:

@ jabba: just throw a mule in a regular scanner and then trace the lines with a CAD software
- the results are fairly accurate

Awesome technology!

Interesting how it wouldn't pick up the pivot screw on the left side. Reflection?

I am guessing he skipped scanning from one angle, otherwise it would have shown up properly.

Yeah, I tried it on my scanner a couple years ago, but it's an old one and came out way off for some reason.

Apologies I missed your reply. Good eye! :D

Actually, what happened there is that due to being a highly reflective, flat, round surface, the scanner mistakenly picked that spot up as a “location target”. Location targets are these ~3/8” adhesive stickers with ~1/4” reflective dots that you apply to a model (or on the desk surface, as I did here) to help the scanner locate itself relative to the scanned part in 3D space.

For some reason, when I tried to tell the software that that spot wasn’t a target, it deleted the entire surface for some reason, and I was left with a 3/8” hole. However, it deleted the target fine on the clip side of the knife. Who knows, probably user error on my part due to being new with the scanner. :spyder:

Thanks for the info. It's hard to believe it picked all that up relative to a target on a desk next to it, pretty amazing stuff.

[SpyderPhreak]

It’s pretty cool how well it works!!! Notice how it even picked up the Spyderco Bug on the pocket clip? :D (Did I mention, this scanner was purchased to laser scan a spacecraft... :eek: :cool: )

Ideally, the targets are placed on the object, which is large enough that the targets are basically irrelevant. For smaller objects, like this pocket knife, you place the targets on a fixed surface (or surfaces, like the inside corner of a box) around the object. The scanner likes to see 4-6 targets minimum at all times for optimal results. :spyder:

Wow. Very neat!!
