I already drank the coffee. Then I put the GADGETEER logo on what was left.
The xTool O1 Omni printed white lettering and a ring of tiny gadget icons onto a used espresso puck. In the close-up, you can pick out a camera, headphones, a game controller and a bicycle against the rough brown grounds. Apparently, even my coffee needs a second job.
This started with Keurig’s new AltaRounds. Their shape reminded me of the spent pucks from my espresso machine. Keurig starts with fresh coffee and a plant-based coating. Mine had already supplied the caffeine, which made it a ridiculous but very tempting canvas.

The texture is part of the print
The O1 prints UV-curable ink onto the surface, and ultraviolet light cures it as it prints. White ink makes the design visible against the dark coffee grounds.
My saved setup shows UV flatbed mode, Standard precision and the Texture setting with White + Color selected. The settings overview displays 2mm. That’s the value in the software; I haven’t measured the finished relief. The close-ups do show the white lettering and icon edges standing out from the coarse surface.
The job preview estimated 21 minutes and 34 seconds and listed white ink and varnish, a clear ink used for surface effects. That time is a software estimate, not a measured runtime.
A silly test with a useful next question
A coffee puck puts the material in charge of the design. The dark background makes the white artwork easy to see, while the grains and uneven edges stay part of the object. A printed keepsake made from it would carry some of the character of the original coffee.
That thought led me to my after latte project. Its first short video shows the idea under its own name, with a white smile of lettering on the coffee.
For readers with a printer, the practical starting point is a material the manufacturer supports. xTool’s O1 material guide includes wood, acrylic, paper and other surfaces, with preparation requirements that vary by material. A small sign, a personalized tag or a display piece gives you a useful project to build around.
The coffee version still has work ahead of it. A readable first print doesn’t tell me how well the puck survives handling, how securely the ink holds or whether another puck gives the same result.
Watch the idea take shape
The first after latte video gives the coffee a second act. The next one, “Life crumbles, sometimes,” shows how fragile the puck can be.

The coffee stays finished
xTool warns that UV-printed areas aren’t intended for direct contact with food or drinks. This puck is for display. It won’t go back into the espresso machine, and the original grounds don’t establish that the ink-covered result is compostable.
For now, I have a physical answer to a wonderfully unnecessary question: can my coffee leftovers carry the GADGETEER logo? This one does.
Some people make latte art. I’m making after-latte art.
