Signing your 3D prints with digital/physical signature #3dthursday

SIgningPrints

Here’s a technique that a few of us have tried over the years to tuck in our signature to the work we create: model a signature into the interior of a 3D printed object. I tried this with grids of binary, but TheNewHobbyist went for these pleasing, direct blockletter initials. Via 3Ders.org:

Raster made a lightweight frame to hold a GoPro Hero3 camera and shared the design STL files on Thingiverse. Some days later he found a GoPro Hero3 Frame was sold on Shapeways by someone else, not himself.

It happens almost everyday that things you made are copied by others. Chris, a Chicago maker came up with a speical solution: signing your 3D prints with a digital/physical signature.

‘Taking my username’s initials I sized the letters to fit within the structure of the print. The letters are 1.0mm in height which at my current layer height of 0.3 mm prints 3 layers of initials in the print before covering the top and continuing the print. Pictured in the header image of this post is a finished print that includes my initials inside. You really can’t see any evidence of my initials on the completed print so it doesn’t really modify the intended appearance of the peice. However if you’re printing the part yourself you will see my print “sign” itself with my initals about 25% into the print.

‘While this “digital/physical signature” isn’t impossible to remove I think it’s a good way for anyone from artists, engineers, and hobbyists to make their mark on their 3D designs. It’s pretty cool to watch this being printed as you can see in the video below. It’s almost like a secret message from the model’s creator. I think it would be pretty cool to see logos or initials “sign themselves” in the middle of more prints that I grab off the internet. It’s a good way to connect the cool object you’re printing with the cool person that designed it and you really don’t need to do anything to see it, it tells you who made it while it’s printing!’
