7 Easy Steps to 3D Print A Thank-You Stamp

7 Easy Steps to 3D Print A Thank-You Stamp

One of the most enjoyable parts of using a desktop 3D printer is the ability to make your own unique designs come to life in just a few hours.

Formlabs’ Flexible Resin produces smooth surfaces and compressible parts that are perfect for custom stamp-making.

Follow our 7 easy steps to design and 3D print a Thank-You stamp!

What You’ll Need

The following items are needed to create custom, 3D printed stamps:

  • Formlabs Form 2 or Form 3 SLA 3D printer
  • Formlabs Flexible Resin
  • Formlabs Standard Resin, any color
  • Adobe Illustrator, Inkscape, or other vector graphics software
  • Blender or other 3D modeling software

1. Draw your design in a vector file

Once you have a design in mind, draw it out in vector graphics software, such as Adobe Illustrator or a free program like Inkscape. Save it as a Scalable Vector Graphic (.SVG) file, which is compatible with most CAD programs.

Make sure the design is mirrored so that the stamp itself is the reverse of what will appear on a stamped surface.

Design the stamp as a vector graphic, making sure to mirror the final stamped image.

2. Convert the vector design into a 3D model

Converting a vector file into a 3D printable model is straightforward in most CAD programs. For this step, we used Blender, a free 3D modeling software. In Blender, import your two-dimensional .SVG file and convert it from a curve to a mesh (Alt+C). Switch into Edit Mode (Tab) and use Extrude (E) to turn it into a three-dimensional shape.

Extrude the design to make a three-dimensional shape.

3. Add a backing plate

In Blender, still in Edit Mode, add a rectangular mesh (Shift+A) and use Extrude (E) again to make it three-dimensional.

A backing plate will make the final print sturdy.

4. Export as an .STL and open in PreForm

Export the custom stamp 3D model as an. STL file and open in Formlabs’ PreForm software. Set up the stamp to print with Formlabs Flexible Resin with a layer height of 100 microns. 3D print your stamp directly on the build platform.

Make sure the stamp is the size you want. The stamp used in this tutorial is 65 x 50 mm, or approximately 2 ½ x 2 in. If your Blender model is too small or too large, use the Size tool in PreForm to make adjustments.

Prepare the stamp for printing in PreForm.

5. Print the stamp

Press print! The stamp used in this tutorial took 4 hours and 15 minutes to print.

6. Print a stamp handle

Model your own stamp handle or use the one from this tutorial, which you can find on Pinshape. It fits the corresponding stamp snugly, without glue.
