PiBurn 4.0 Rotary LIMITED American Pi Edition

PiBurn is a patent-pending roller-style rotary attachment for laser engraving machines. The innovative PiBurn rotary allows you to engrave cylindrical objects such as cups, tumblers, glasses, bottles, and champagne flutes with ease and precision. It will securely hold the object while rotating so that the laser can engrave it line by line.

Why buy the Pi?

We asked Todd Tomlinson, who runs an online customization business: Visit His Etsy

If you do the math — say you make just $10/tumbler (I make more sometimes) – that’s only 80 tumblers to pay for a Pi. My first order was for 48 — so paid for 1/2 in one order. Tumblers/Mugs are the easiest thing to sell as everybody wants / uses them. Stan Altshuller and Len Karchevsky created an amazing ATM machine 🙂 for your shop. Have faith in your ability to pay for it quickly.

Some customers charge 20$ and even more to engrave tumbrels. But how should our customers go about selling their awesome drinkware?

Here is a suggestion: All you have to do is get in your car – drive down main street in your city – take pictures of the businesses who would likely use or sell tumblers – make one – with their logo – walk in and deliver it and have a friendly conversation. Watch the orders pour in.


Here is a “How To” video from the one and only That Mom with a Laser!



PiBurn 3.0 comes with standard feet, but there is an option for magnetic feel available. This is ideal for the slanted bed of Boss and Koenig machines but can be used with any machine. When you don’t need them, they fold away.

No assembly required! Your PiBurn comes fully assembled, and ready to go!


PiBurn now comes with a Full 1 year warranty for motor and all parts.

You don’t have to worry about the longevity of the PiBurn. We have customers who have engraved thousands of tumblers, and it is still going strong! But now, put all your worries to rest for good because each PiBurn comes with a 1-year warranty on all parts and motor.



Feel the Love!  Here is what our customers are saying

I’ve owned two lasers and three rotaries prior to buying the PiBurn. I won’t say I’m an expert as there are many laser owners who have done far more tumblers than me.

I’ve always been leery of the accuracy of rotaries. I could never run something twice and expect it to be exact the same second time. That is until now. The PiBurn has allowed me to step my tumbler game up. I have complete confidence it’ll be the same every time and I’ve tested it. This PiBurn works flawlessly on everything from wood pens (I make these as well) to growlers and everything in between. My only regret is I didn’t buy my PiBurn last year!!

I own two rotaries. I purchased the first one at the same time I purchased my laser. I got consumed in learning to operate my new laser and before I even had a chance to set it up my first rotary, the laser community had perked my interest in the PiBurn. I did my due diligence and researched every source I could find. I was truly hoping to be able to talk myself out of the PiBurn (since I already owned a brand new rotary!), but everything I saw/heard convinced me that it truly was the best option – both for ease of use & in it’s ability to handle a greater variety of sizes.

I’m still relatively new to this scene, but after running dozens of tumblers/water bottles, I am convinced it was money well spent. I making a very quiet entrance into the business side of things (primarily through word of mouth), but these tumblers have been my most popular request and biggest money maker thus far.

It’s important to note that the customer service has been superb. I have really appreciated how attentive Stan & Len are. I’ve only had a couple questions/concerns so far, but their responsiveness has been impressive!

Jen Spencer (verified owner) 

What can I say, best accessory purchase I’ve made for my laser. I wanted to try a rotary and even purchased one from my laser manufacturer, that was a mistake. I researched and found the PiBurn, ordered it and haven’t looked back since.
I have 48 tumblers to engrave this weekend and this will be no problem for the PiBurn.
If you are looking for a rock solid, easy to use rotary then look no further, order yours immediately!

Michael Kirk (verified owner)

My old rotary was made of 3D-printed parts. After only a year of heavy use. It started to bend. I ruined so many cups because of this! Once I found the Pi I laughed ,thinking it was overpriced. But I needed a good rotary so I decided to bite the bullet and buy it.
After using it for about 4 months now I can’t believe how cheap I was being!!
This Pi is easy to use. So simple to switch different sizes cups. It’s a time saver and also a quality build! I have not messed up one cup since switching over. I love the Pi!!

Jason M. (verified owner)

This thing is amazing! It’s really expanded our business and after just a week it’s payed for itself! Customer service is amazing, shipping was fast and instructions were very simple/Helpful when I assembled. I think they even come assembled now so even easier!

Matthew Reger (verified owner)

I have owned several rotaries and this one by far outshines them all. The team behind it are fun and helpful. I wish I had seen it sooner so I could have avoided some of the headaches I had with the others.
