One of the main benefits of 3D printing is the ability to make your own customized products. In this tutorial, we’ll be making a simple stamp that you can customize with your name or logo. We’ll be using the 3D design software Onshape, which is free for hobbyist use.
You can grab the design files for the stamp handle here! Any stiff filament or resin should work for the handle and a flexible material is best for the stamp itself. If you’re not sure what material to use, check out our 3D Printing Materials Guide!
Creating a Custom 3D Printed Stamp in Onshape
Step 1: Create the base for the stamp
We’ll get started with making our stamp in Onshape. Open a new document and create a sketch on your Top plane. Draw out a center point rectangle (or use the shortcut ‘r’) then select your dimension tool (or use the shortcut ‘d’). Set one edge to 65mm and the other to 50.5mm. Now you can save your sketch and extrude (shortcut ‘shift – e’). We’re going to want a depth of about 5.5mm.
Step 2: Add lettering or design
Now it’s time to add some lettering! Create a new sketch on your top face and select the text option. Drag out the selection box (don’t worry too much about sizing for now) and type whatever you’d like your stamp to say! Hit enter and you should see your text.
Sizing the text to fit the stamp can be a bit tricky. We’ll be using something called constraints. Select ‘coincident’ or press ‘i’ on your keyboard. Now select the edge of your text box and the edge of stamps. You’ll notice that the two edges are now joined together or “coincident”. Do the same for the other side and your text will match the size of your stamp. Tip: if you’re having trouble, select the “show constraints” checkbox and make sure your constraints match those pictured below.
Extrude your lettering to a depth of about 3mm and your customized stamp is finished! To save, look for the “Parts” box towards the bottom of your screen and right click on “Part 1”. Export to an STL and you’re ready to print!
Step 3: Choose your materials & print it
We printed on both a Form 2 and an FDM printer. The handle was printed in both Formlabs new Tough Resin and Proto Pasta’s special edition pine filament. The stamp itself was printed using Formlabs Flexible Resin and eSUN’s flexible filament. Your stamp will fit snugly inside the handle and shouldn’t require any glue.
Step 4: Get stamping!
Time to test it out! We used a typical stamp pad which can be bought from most craft stores. We found that flexible materials worked best for the stamp but harder plastics may work as well. We’re excited to see your customized versions and make sure to upload your prints to the original design page!
