How to Make a Rubber Stamp with A Laser

Janice SherriffsUpdated: Feb 17, 2023

Rubber stamp making is one of the things that is often stated as an example of what you can achieve with laser engraving.

However exactly how I wasn’t sure of, or what I’d need to actually make a stamp myself.

But, after my success with testing in my last blog, I knew that I could at least find the perfect settings.

There are a few basic questions about stamp making to answer.

What supplies do you need to make a stamp?

You need a laser engraver, thinking it may be sulking as I’d been using my 3018-Pro CNC quite solidly recently, I went back to my Mandrill CNC Router 3036 with 40W Laser.

You need some rubber stamp material.

When searching Amazon, or other shopping sites for stamp material, you will find 2 main sorts: thick rubber blocks and sheets of thinner rubber, suitable for use with a laser – make sure as always that what you’re going to use is laser safe.

You need something to attach the rubber to, I got some small wooden blocks.

And of course, you will need your stamp design.

How do you test the material for speed and power settings?

I’ve done lots of testing of various materials over the last few years, but as I said in the last blog, the YoraHome team have developed a phenomenal test file for everyone to use, so it was the perfect opportunity to try it out again.

As I had done a “cut down” version of the file previously, I decided to use that.

How do you attach the rubber to the machine?

To attach the rubber material to the machine base, you can use tape.

Or I found the best option to be double-sided tape.

So, once in place and focus set, just press Start and away it goes.

How do you decide what works and what doesn't in a test?

You can see of the options used, some were a bit too high and burned all the way through - 1000 mm/min 40% for example, some didn’t make much of a mark 4000 mm/min 10% as an example.

Using my YoraHome Verniers (YoraHome 6 Inch Stainless Steel Digital Caliper) to check the thickness of the material – it was advertised as 3mm, I found it to be 3.25 mm

I then used the verniers to check the depth of the engraving.

The bottom edge of the verniers sat perfectly on the edges of the engraving for the probe to measure the depth.

Realizing that the depth of the engrave shouldn’t be more than half the thickness of the material, I could then choose the ideal settings – 5000 mm/min and 40%

Right, time to make a stamp!

How do you make a Rubber Stamp with your YoraHome laser?

Open LightBurn.

Open-lightburn-to-design-rubber-stamp

Go to Create Text on left of screen.

Click-on-create-text-button

Type the text you want to use and choose the font.

Select-text-and-choose-font

Click on the Select Arrow to select the text.

Click-on-select-arrow

You can now adjust the height of the text to what you want. Knowing that my wooden blocks were 25 mm, I set my height at 15 mm.

Click on Edit, then Invert Selection.

Click on Create Rectangle on left of the screen.

Then set the size of the rectangle of your planned stamp – the size of your wooden block, set this rectangle in a different colour.

Go to Edit, Select all, then to Arrange, Align Centers.

Set the power and speed from the test 5000 mm/min and 40%, I also set my lines per inch to 508 – double the standard setting to make the cut image finer, you also need to be able to cut out the stamp, so set the rectangle to line and set your speed and power.

Once the engraving has completed, you will be amazed at the detail.

Let the cut take place as well.

At this point, you can remove the rubber from the machine, detach the stamp and attach it with glue to the wooden block.

And time to try it out.

Well, that looks brilliant if I say so myself.
