I need some info on something...I have a custom Wortling figure...I was wondering if he can be 3d printed (cloned) but in a smaller size...Chibi keshi or M.U.S.C.L.E. size if chibi is too small...Original sculpt is roughly a little under 2.75 inches tall...A hair over 2 and a half...Closest thing I figured on a way it could be done is laser scanned, and then reduced in size and printed in smaller scale...Is this the best/only way to do it?

you can scan an object with nothing but pictures.

 

https://www.instruct...-Just-a-Camera/

 

to print it smaller, you'd have to figure out the scaling to get the size desired. unless you are using a slicer program, such as  cura, which you can just set the size you want. its in metric, so you might need a converter if your are inexperienced in the conversions needed. the model will also need to be in the correct file format, which is an .stl file.

 

How much do you know about 3d printing?

Thanks for the info stoffhimel...I don't know much...I have no printer, so I'll probably have this done as a commissioned piece if I decide I want it...

Scanning a figure to print is pretty expensive... you would be better off molding and using shrink-it to shrink the figure, then molding the shrunk version and casting from that mold. Still not cheap.

Smooth-on Oomoo 30 (trial size) - $30
Shrink-it - $20
Smooth-on Smooth cast 325 (trialsize) - $30
Universal Mold release spray - $15

There is shrinking resin you could use, the opposite of Hydrospan.

"Hydroshrink". ;)

 

But yeah, while I have exactly zero experience molding and casting, I've seen some miracles worked with Hydroshrink and Shrink-it.

 

What I do have experience in is 3D scanning and printing...and honestly, I've NEVER seen good scan results from any of the myriad photo-stitching programs out there. At least not objects as small as toys...maybe buildings & shit like that? stoffhimel, have you actually used any of these programs to scan a mini successfully??

 

But if you do get a figure scanned properly (or otherwise obtain a 3D model of it), getting a high-resolution print from an online service like Shapeways wouldn't be too expensive (under $50).

I have not. I haven't scanned anything. I've been considering it, though.

Hmmm...Seems like if I can't find someone who can do it it's a no-go for me :unsure: Don't have the material or tools to do it myself...

Same. I wonder if there's a website out there that actually compares all the photo-stitching "3D scanning" programs out there. It's intriguing software, for sure...especially because for the most part, these programs are FREE! But the thing is, while they *all* promise amazing scans, I've yet to hear about real-world users being successful at scanning tiny, detailed items with them. And christ, there are SO effing many of them. Are they ALL ass? Or is there just one or two out there that can actually deliver??? I personally don't have the time to do the research myself, but man...even if there was just one program out there that could give us accurate, quality scans of tiny objects without raping your wallet on high-end scanner hardware, it would be pretty epic...

The best scan I've seen was a chicken sandwich that was painted with primer. I've seen nothing else like that since.

 

its was a laser scan, so yeah, not really all that applicable.
