Photon Printer - Micro Laser Engraver

The Photon Printer is a 3D printable laser engraver made from recycled DVD Drives. Software and build instructons are available in the downloads. A list of necessary components is in the instructions.

The Photon Printer started out as a quick weekend project then quickly escalated when I saw that there was room for improvement in the current designs. Designing the components was a fun exercise and the end result was satisfying.

Safety - None of the designs I have seen have any sort of shielding around the laser. Given that even a 5mW diode can be dangerous any sort of engraver should have safety features. These include
• A full enclosure to block reflected laser light
• Roller door access
• Safety cut off switch on door
• Angled ventilation to prevent light leakage


3D print-ability – Printing allows for a lot of features that are not included in other versions.
• Accurate positioning of components
• Fits a wide range of DVD Drives
• Z axis fine tuning adjuster
• Built in roller door guides
• Custom axis mounts
• Low part count
• Ease of assembly
• Buildable by people without access to machining tools
• All parts have one large flat surface to aid in printing


Features
• Coarse laser height adjust for material thickness compensation
• Fine laser adjust for focusing
• Spring tensioned Z adjust to reduce vibration
• Sliding lugs to fit…
