When these markers are finished, each die carries white graphics burned into black PLA: the word INFECT, an exclamation mark, and the Phyrexian symbol. They are custom markers for Magic: The Gathering keywords, made specially for a customer, and they sit on the table as visible markers rather than being rolled.
The dice were modeled in Tinkercad, along with a green alignment jig that holds them in individual slots on the engraver bed. Four dark blank dice go into those slots, the lid of the enclosed desktop laser closes, a start button is pressed, and the 3W module on an xTool M2 engraves the top faces. Between cycles the enclosure is opened and the dice are rotated to expose new faces, then the laser runs again for every side. The settings were power 100, speed 600, one pass, 200 lines and min power 5.
Some details stand out. Each die weighs just 1.6 grams, and the maker had to put five on a scale at once for it to register. Anything going under the laser must stay below 25mm tall, and the advice given is to test on a 150x150x3mm square and to pick dark colors only, because light shades do not take the engraving well.
Two open points remain. The jig needs modifying and reprinting, since the top slots cannot be used within the 3W module's range. And the maker is unsure how well the dice would work for actual rolling, as that would take a lot of calibration. Even so, the maker clearly loves how this module engraves printed PLA, calling the detail something 3D printing alone could never achieve.
