How to Make a Custom Wax Seal Stamp Using Fiber Lasers
If you are looking for a new business opportunity for your desktop laser marking machine, engraving stamps will be a great way to go. All you need is a fiber laser and a deep engraving vector file. In just thirty minutes to an hour, you’ve learned a new skill. Whether it’s just for a stamp DIY hobby, or to give a friend a personalized wax seal stamp, or even launching a custom metal stamping services business, learning this skill is definitely worth the investment!
Metal for Stamping: Choosing the Right Blank
When people talk about wax seal stamps, they often focus on the design or the wax color, but the metal for stamping itself plays a much bigger role than we realize — especially when the custom metal stamp is made via laser engraving. A good wax seal custom stamp needs to be easy to engrave, strong enough to keep its shape, and friendly to hot wax when stamping.
Brass, the most common choice for making a wax seal, and for good reason. It engraves cleanly with a fiber laser, holds fine details well, and doesn't change shape after frequent metal stamping. When hot wax touches brass, it cools at a comfortable pace. Just as important, the wax releases smoothly, making it the top choice for a diy wax seal stamp.
Stainless Steel, much harder and extremely durable—perfect for a personal metal stamp that lasts a lifetime—but it's also trickier to engrave (you probably need a 60W fiber metal laser engraving machine at least). Wax on stainless steel cools more slowly, so it is not as beginner-friendly as brass.
Copper, looks great and can show very fine details, but it transfers heat very quickly. Unlike the two above, copper is often chosen by craftsmen for metal stamping jewelry and artistic hand-engraving rather than daily high-volume use.
Put simply, a custom metal stamps project isn't just about the metal being "hard." It's about how well that metal works with melting wax heat and laser engraving. Brass sits right in the sweet spot for both the maker and the user.
How to Make a Wax Seal Stamp
Lasers have specific laser engraving fields — I mean, each laser has its professional engraving materials. In this guide, we talk about how to make a wax seal using a Fiber Laser. If you are interested in other stamping diy projects, like custom rubber stamps, a CO2 laser might be better.
And for the "nova" in this desktop laser engraver family, UV Laser does a great job in making a custom rubber stamp. During engraving, UV lasers remove material cleanly, resulting in smoother edges and engraving stamps that print clearly without smudging.
Get a Design File for Your Seal
There are two ways for making a brass wax seal, deep laser engraving and 3d laser embossing. So it is better for us to pick dxf file and gray-scale depth map for stamp making.
It is easy to make custom wax seals — I mean, ones only combined with words. You can directly design the metal stamped font in LightBurn. For a 20W fiber laser, set the parameters like power 100%, speed 100mm/s, and frequency 20kHz for the deep passes.
But if you would like to make a pattern-like wax seal, the file-processing will be a bit harder. First, use a service to get a background-removed image for your custom logo stamp. And just import your files into Adobe online service, you even don't need to sign in, you can get a background-removed image file.
For people who know their way around PS, you can get a 3D grayscale depth map with just a few steps. But for those who have never downloaded PS (and let’s be honest, that includes me), we use AI tools. A website named SculptOK is a lifesaver for newbies. I'm not being paid to say this, but new members get 100 free credits—a pretty good deal for your custom wax seals!
This is the final file I got from this useful website. For now, the seal making job reaches 50%, there are three more steps need you to go.
After importing the file, make sure you find this interface, double click the parameters on the top-right, turn "Negative Image" and choose the image mode "3D Sliced".
Why use the "Negative Image" ?
The core logic of 3D engraving is that the black areas represent material removal (depth) while white areas remain at the surface. For an embossing (positive) design, your text should be white on a black background; for a deep engraving (negative) design, the text should be black on a white background. Always use the Preview window (Alt+P) before firing your 20W fiber laser: any area shown in black is where the laser will "carve" into the material.
Cleanup & Polishing
After engraving, do not move the seal! It’s time for the cleanup—another crucial bit of engraving stamp work. We do this to remove black oxides and to polish the surface. Parameters we recommend for a 20W machine are:
| Process Stage | Speed | Power | Frequency | Hatch Interval | Hatch Strategy |
| Cleanup Pass | 2000 - 3000 | 20% - 30% (4W-6W) | 50 - 80 kHz | 0.04 - 0.05 mm | Bi-directional Scanning |
| Final Polishing | 1000 - 1500 | 35% - 45% (7W-9W) | 60 - 80 kHz | 0.01 mm | Ultra-fine Cross-hatch |
Pro-Tips for Using Your Wax Seal Stamp
Watch the Heat. Do not overheat the wax. If you do, your diy stamps will leave unsightly "honeycomb" pits on the surface.
The Press. Wait 10-15 seconds for the wax to become "honey-like." Press the custom wax stamp vertically into the wax—don't tilt or wiggle it!
The Big Chill. Keep pressing for about 20-30 seconds until the wax seal is completely solid. Then, gently lift the stamp.
Ideas to Make a Wax Seal
Artistic Crafts & Viral Content
There are plenty of influencers using unique custom wax seal designs to gain massive followings. It’s all about the "eye candy"—using multi-color wax to turn a simple seal into a viral masterpiece.
Personal Logo & Boutique Branding
Some boutique stores use their own custom logo stamp to seal packages. This is also a huge trend for wedding invitations, where a personalized metal stamp makes the mail feel like a royal decree.
Custom Signet Rings
This is where things get really stylish. You can use your 20W fiber laser to create a seal engraved on a ring. These custom wax seal ring options are a massive hit for jewelry makers, allowing someone to carry their personal brand right on their finger.
Custom Ice Stamp
One of the coolest trends right now is using brass for a custom ice stamp in high-end bars. It uses thermal conductivity to melt a logo into ice in seconds—a perfect way to show off the extreme depth your 20W fiber laser can achieve.
Conclusion
Making your own exclusive brass wax seal stamp isn't a hard task; the hard part is usually just convincing yourself to stop overthinking and just hit "Start." Whether you are looking for metal letter stamps or a complex 3D design, once you master the "Deep + Clean" workflow, you’ve got a skill that’s perfect for hobbies or a custom metal stamping side hustle. Grab some brass, fire up your 20W machine, and let's see what you can create!
