The crew digs into a wave of new updates in the laser world, including Johnson Plastics Plus buying LBT and what that means for titanium-dioxide marking supplies. Alex walks through a day of CO₂ testing hell with tumblers that refuse to bond, pint glasses that behave better, and how small coatings can derail a whole project. The discussion circles around metal marking fundamentals, why delivery method matters, and how easy it is to overpower TO₂ before it even activates. There’s also talk about diode vs IR modules, first-show lessons from the community, and whether some of these hybrid CO₂/diode/galvo machines are worth the hype.
