Home Built CNC Laser Build Log. Home Built 40W CNC Laser Project Overview Note: This design has been superceded by the 2.x Laser.
There is a blog post on it, information on the wiki and a lot of discussion on the forum. This was designed as a "self replicating" laser cutter engraver'. What this means, is all of the high tolerance complicated parts can be made on a laser cutter. This is not a mamby pamby little diode laser than can slowly cut through a piece of thin black tape. This was designed to be a dirt cheap, but fully capable laser cutter. The buildlog is presented blog style (most recent entry first) if you want to go view it the other way click here...

DIY Laser Cutter for PCB Stencils. Friday, 29 March, 2013 18:27Last Updated on Friday, 29 March, 2013 23:14Written by NJC Introduction Are you sick and tired of using a tooth pick to apply solder paste?
Are you still using through hole components because you don’t want to deal with soldering surface mount devices (SMD)? If so, this post provides you with guidelines for building your very own laser cutter for cutting PCB stencils. With a total cost of approximately $200 (it can be significantly less if you already have parts laying around), this project can pay for itself very quickly. The laser cutter can cut very accurate stencils from adhesive backed black vinyl sheets (on Amazon) for ICs with a pitch of 0.5mm (SON-10) and 0402 resistors (and possibly even smaller parts). It gets better. Before going onto how I built the laser cutter, I want to give you a quick overview of the design flow once everything is up and running: First, I create a circuit board and order it from either Seeedstudio or OSHPark.
Parts The Build. Builders: selective laser sintering part 8: reciprocating laser cutter. Hi folks, On Saturday afternoons, like any good grad student, I visit my parents place to do my laundry.
While it's spinning around, my dad and I usually get up to some neat projects, and this is what we worked on this week. I've had an idea for a while that one might be able to build an inexpensive laser cutter using a 1 Watt IR laser diode, as opposed to the larger 20-100 Watt CO2 tubes traditionally in something like an Epilog laser cutter, using a bit of a trick. Traditionally laser cutters have a lot of power, and (to my knowledge) are generally fixed focus, meaning that the focal point -- the hottest portion of the cutting beam -- stays at a fixed depth relative to the material that you're cutting. Because commercial laser cutters have so much raw power, it doesn't so much matter that they're slightly out of focus at the top and bottom of the material -- even diverged, the beam still has enough power to cut.
The test rig is beautifully simple. Thanks for reading! DIY Inexpensive Laser Cutter with Infrared Diode. A laser cutter works by following a predefined path to cut the material underneath.
Industrial grade CO2 lasers use the “traditional method” shown below because they have sufficient power range (20-100 Watts) to cut through steel like butter. But, of course, they’re expensive so when you need a laser cutter that’s within a DIY-ers budget, you learn to innovate: Don’t Miss: Our DIY Laser Projects The ‘reciprocating laser’ idea uses a low power, 1W IR diode (less than $5 on eBay) to create which moves the focal point of the laser along the Z-axis according to the depth of the material. The focus of the beam is manually adjusted (for this version of the build) so that the laser steadily bores through the depth of the material.
The result is an inexpensive, 3-axis laser cutter. Build Laser Cutter. This is a very fun project if you have a lot of time and love to build everything rather than just going to the store and buying it.
This guide will show you how to build a CO2 laser cutter with a cutting bed size of 38X17X10. It costs about 1200-1500 to make at the time of writing. Video of the system cutting cardboard: I apologize in advance, this is my first instructable and I am not the best writer. First thing to know about building a laser cutter is that this is an extremely time consuming, dangerous, and difficult process. You should not work alone.
Things to know when working with lasers: * Death: Voltages as high as 50000 volts with currents up to 100 ma. Whenever the laser system is powered: * Eye protection should be worn by you and everyone else * Doors and windows should be closed * Insure adequate distance between you and high voltage terminals The laser used here emits infrared light which is invisible to the human eye.
