RE: [rp-ml] QR code on Zcorp plaster?

I agree that ZCorp is probably the way to go for QR codes as a proof of
concept because placing the image on the part is relatively easy.
However, if you are designing the QR image as a relief on the part you
can build in other 3DP methods such as SLS. You just need a stamp pad or
inked surface to stamp the bottom of the parts and highlight the code.


Also, see 3D System's SLS Design Guide - Plastics, #4 "Barcodes" (quoted


Aztec Barcodes appear to be optimal for SLS Manufacturing. Make the
cells <1mm cubed. Note that you must apply contrast ink to the raised
surfaces of the barcode to enable or accelerate image capture when
exposed to a scanner.

Hi Jonathan - I have made QR codes on Objet models - I think it would be
much easier on Zcorp models. For Objet, I needed to convert them to 3D
STL files, for Zcorp, you could just map the image.


I use this website ( to create the
code, as a JPG and then I used magics "create from bitmap" command. You
could just use Zedit or Magics to apply the code as a texture.


Let me know if you need more than that.

Subject: [rp-ml] QR code on Zcorp plaster?

anyone done any QR codes on ZCorp plaster models?


i am hoping to finalize a project by getting a couple of replacements
for model exhibited at SIGgraph in 2008 and want to test whether i can
get QR codes on these. anyone interested in helping me complete a
project by testing this on a series of /shelled/ mathematical models?


i would like to make these available to mathematics departments and now
that i plan to shell them i can supply them at a reduced cost. if i can
get QR codes on them this would be nice in order to identify where they
came from.


anyone tried this? a google search seems to have turned up indeterminate
results. <> |
