Photon Printer - Micro Laser Engraver

cults3d

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. Legacy file are available at http://www.thingiverse.com/thing:2277397 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 a range of DVD Plates • Fits a wide range of laser housings • Suits an Arduino Uno and CNC shield for an easy build • Low parts count • Low cost Video https://youtu.be/hiiEqVzhY4s Update 2017-10-04 Updated instructions. Software added. 2017-07-07 Corrected PPV3 X Laser Mount 2017-05-06 Parts strengthened. Laser holder modified to hold a variety of heat sinks. Laser driver bracket added. DC jack hole added. Instructions expanded. Legacy files moved to another page. 2015-10-01 Instructions updated, Solidworks and STEP files added 2015-09-27 A small gap added to top of nut traps to compensate for sagging during bridging. 2015-09-27 V2 uploaded - Now suits an Arduino uno with CNC shield. Sliding mounting lugs support a wider variety of DVD Drives. Springs are now printed, no need to tap the parts. 2015-07-17 Improved electronics schematic by pepperm 2015-07-15 Electronics Schematic updated in better quality. 2016-05-24 Step files updated
