3D Print + Silicone Caulk = Custom Stamps

youmagine

Could you make a custom stamp using only 3D printed plastic? Absolutely, plenty of designs are available online. TL;DR I wanted to experiment with silicone and fuse it with printed plastic:) I was playing around with silicone caulk to create mini figurines using 3D printed molds. After the silicone cured, I noticed its flexibility and thought it could be a great substitute for rubber parts in stamps. The flexibility would likely improve ink transfer compared to hard, potentially uneven plastic. Using the plastic as a negative mold allows for finer details and more flexibility but may result in flimsy silicone if overdone. Without any stamp pads, I colored the image with a permanent marker and then stamped it, achieving decent results in my opinion. Instead of designing a new handle from scratch, I modified Pumpkinwaffle's design to suit my needs. The handle requires support during printing, but you can remove the column for alignment to print without support.
