Introduction: How to Make Stamps With Sugru

Sugru's rubbery texture once it's cured and it's moldability when fresh out of the package lends itself well to stamp-making.  I played around with several different methods of making stamps with this material and was quite happy with the results.

Step 1: Materials and Tools:

  • Sugru (I made all six stamps with 2 packs of Sugru)
  • Wood -cut to size and sanded, corks work too depending on what size stamp that you want
  • Carving tools, utility knife, nail etc.
  • Cling wrap
  • Dish soap
  • Pencil, scissors, glue
  • Wax
  • Craft foam

Step 2: Getting Started

If you have never used Sugru before (or if you want to buy some) check out their website for instructions and other useful information.  
  • Prepare the wood blocks by cutting them to the size that you need and sand the edges smooth, the blocks that I use were about 2cm X 2cm for the small ones and the larger block was about 4cm X 2cm.
  • Cover your work surface with cling wrap and sprinkle soapy water on it
  • Cut open your pack of Sugru and condition it (knead it for a minute or so)
  • Divide it into two pieces. Cover one side of a block with one piece
  • Make sure the Sugru is an even thickness and press it down on the soapy cling wrap covered work surface to flatten it out
  • When the Sugru is flat and smooth on the block trim off the excess at the edges
  • Repeat with the second block.
  • You can use the excess Sugru that you trimmed off to make another block, or use something smaller instead like a cork.
  • Remember that once you open a package of Sugru you have about 30 minutes to work with it before it starts to cure.

Step 3: Carved Stamps: Carving Before Curing

I first experimented with carving the stamp before the Sugru had cured.  Prepare the stamp as in Step 2. Using a nail and a utility blade carve a shape onto the stamp.  The Sugru is quite soft at this point so it is easy to carve and if you make a mistake you can just smooth it over and start again.  It is important to make the lines thick enough and keep the surface even.  When you're satisfied with your stamp place in a warm dry spot to cure for approximately 24hrs.

Step 4: Carved Stamps: Carving After It Is Cured

Carving the stamp after it has cured is similar to doing an eraser stamp.  Prepare your stamp as in Step 2 and let cure for 24hrs.  With a pencil draw your image onto the stamp.  If you want to have text on the stamp it needs to be a mirror image.  Carve out the shape using a utility knife.  Take your time and work carefully, unlike the stamps in Step 3 you can't smooth over your mistakes. Test out the stamp as you go to see which areas need more carving.

Step 5: Stamps From a Mold: Wax

I wanted to try making stamps from a mold or impression. I experimented with carving an image into wax and making an impression from it.
  • Break up pieces of wax from an old candle and melt it down in a glass jar on a small warmer.
  • Pour the wax into a flat shallow dish (I just used the lid of the glass jar). 
  • Once the wax has cooled and solidified place your wood block onto the surface and mark the size on the wax with a felt pen.
  • You can draw your desired image onto the wax within the space that you marked.
  • Carefully carve out the shape in the wax.  Make sure the edges are smooth and that it is carved to an even depth.
  • Remove any wax shavings or debris.  You can heat your carving tool to make it easier.
  • Once you are satisfied with your carved wax, prepare the stamp as you did in Step 2.
  • With your finger coat the wax area that you carved with soapy water.
  • Press your stamp down onto the wax with firm and even pressure.
  • Lift off and check how it looks, if you are not satisfied with it, you can smooth it over and try again or use your carving tool for some touch ups.
  • When you are happy with the stamp place it in a warm dry spot to cure.

Step 6: Stamps From a Mold: Craft Foam

I found that using a wax mold worked for larger more solid shapes but if you wanted to do fine lines or text it was too brittle to carve.  So I tried craft foam.
  • Mark the size of your wood block on the craft foam
  • With a pencil draw your shape, image, text or whatever onto the foam.
  • Carve it out with a utility knife, make sure that the lines are not too thin.
  • Cover the foam in soapy water and prepare your stamp as in Step 2.
  • Press the stamp onto the foam with firm even pressure.
  • Lift off and check how it looks, if you are not satisfied with it you can smooth it over and try again or use your carving tool for some touch ups.
  • When you are happy with it set it in a warm dry spot to cure.

Step 7: Labels

To give the stamps a finished look I added labels to them.  Simply stamp each one onto white paper. Cut out the stamped image and glue onto the top or side of your stamp.   Cover with clear tape.

Thanks so much! This is going to go a long way in helping me create my custom business logo stamp. Sweet! Even more excited about this when I start thinking about what else I can do just by modifying this instructable for my own needs/purposes :-)

Pretty cool! I've been looking 4 a way of making stamps, but I live in AUS and have no chance of getting my hands on some sugru... :(

author
pjewell (author)HMice2012-10-21

Sugru now shipping to Australia!!!! Hooray!!!
Takes a little longer than they say, maybe a week or two, but it arrives no problems. Now we can start hacking Aus. :-)

Just ordered some Sugru in AU. Arrived in my PO Box seven days after arrival.

ChrysN (author)HMice2012-03-02

I didn't realize they didn't ship there, I checked at the Instructables store and they only ship to Canada and US. Perhaps you can try to win some as a prize from Instructables (actually that's how I got mine). Here is one.

HMice (author)ChrysN2012-04-22

I worked out that if I draw a shape on foam then cut it out and glue it to cardboard I get similar results. My stams have been pretty good so far.

author
ChrysN (author)HMice2012-04-29

Cool, perhaps you could post an instructable on how you made it!

author
HMice (author)ChrysN2012-03-02

Yeah... I'll try but I've got no hope against you guys.... (pro memberships)

well... i got a pro member ship.. gifted actually :) all you need to do is to make some thing never made before by any one lol :)

author

I looked up Sugru - apparently it's something like a moldable silicone. A web search for any distributers in the US came up empty. Does anyone know if/where this can be bought in the US or is there something here (in the US) that can produce the same results?

Thanks

author
ChrysN (author)ladamus2011-02-27

It's only sold from the UK right now at http://sugru.com/.  The cost of shipping isn't to bad.

author
ladamus (author)ChrysN2011-02-27

Is there anything comparable to this product in the US?

author
wocket (author)ladamus2012-01-26

thinly sliced pencil erasers would do the same trick

If you use text this way, you won't have to do it mirror image, right? You can carve letters normally, they will reverse, in the sugru mold, and then they will come back to readability again each time you press a stamp, right? :-0

author
ChrysN (author)shakespeare12122011-08-25

Yes, that's right.

author
shakespeare1212 (author)2011-08-25

So, awesome, thank you!

author
ynze (author)2010-10-22

Great! The different ways to make an image are super. Would the Sugru hold on a rolling pin, you think :-D ? I got to get hold of some Sugru, one of these days...

author
ChrysN (author)ynze2010-10-22

If it is a wood rolling pin like the one you used for your stamps the Sugru should stick really well, great idea.

author
thepelton (author)ynze2010-10-22

I'm not sure. You would have to experiment to find out. I do know that you could attach it to a thick dowel which could be used like a rolling pin. I have seen dowels as thick as three inches. (76.2mm)

author
thepelton (author)2010-10-21

I was thinking that the person who was putting Jack O Lantern faces on Mikan Citrus to give away at Halloween could use some Sugru to make a Jack O Lantern face that could be stamped on the side of the fruit.

author
ChrysN (author)thepelton2010-10-21

Good point, that would totally save a lot of time.

sylrig (author)2010-10-10

This is such a good use for the little leftover blobs of sugru that harden before you have a chance to think up another use for them. I have one right now, in fact, and will try this today. Thanks!

author
ChrysN (author)sylrig2010-10-10

Yes it's hard to predict sometimes how much Sugru you'll need for a project and with a narrow time window to work with it is hard to quickly find another use for the leftover bit.

author
PinkHeart (author)2010-09-29

Very smart idea. I love making my own stamps but never with sugru.

author
ChrysN (author)2010-09-29

Yes, that's true. You can cover mistakes with more Sugru let it cure and try again.

author
krcorcoran (author)2010-09-29

Wow... bet you could use this stuff to fix mistakes you have made on a block print. it looks like it works the same.

author
sunshiine (author)2010-09-26

I received my sugru yesterday and this would be a good way to use it! Thanks for posting this one.

As a rubber stamper myself, this use of Sugru opens up all kinds of possibilites for new stamps. Thanks a bunch! It inspired me to order some Sugru and try this myself. This idea gets my vote.

author
Knotty NY (author)2010-09-19

Very nice! This may be a more cost effective way of making your own stamps

Oh this is a great idea! wow I can't wait to do try this.
For a second I thought the thumbs up for the "Like" stamp was a middle finger.

author
ChrysN (author)npknhdfrvr2010-09-19

That would be a funny stamp to make.
