I wanna know what type of laser can i buy to make a project like this:
I mean only the engraving, not the cut because i know to cut a piece of wood like that it takes a very powerful laser, i want achieve only the engraving.
That is an amazing work from a online shop, i think the depth of the engraving is max 1mm but it’s very very precise. What you suggest?
Thanks for the answer, it’s really cool what that laser do, but costs a lot of money, i see some laser 2W 445nm around 30-40$ with module, i’m looking on something moooooore cheap, that 1mm engraving is really low, i don’t think i need a 400$ to make that engraving work, or I am wrong?
2 Watt really isn’t powerful enough. I have the 2.8 and something like this would take a decent amount of time. Also consider that the price point is for a complete package. Buying components you will need the laser diode, a lens, a heat sink, a power adapter, a driver board, and eye protection.
I set up a 2W laser on my XC ($100 from e-bay, has everything required, diode, heatsink, driver, fans, eye protection, etc.). If I can find some sample g-code or produce some, I’ll try out an engraving and let you know how it goes.
Any idea what the average lifespan of a diode from Jtech would be?
I am real close to pushing the button on a purchase of one and am deciding if i want to go with a 2.8 watt or 3.8 watt unit. so far 3.8 is looking better since I believe I can dial it back but a 2.8 can only be pushed so far.
We never cut at full power for long periods of time with it. We only engraved photos using varied intensity on that machine. It’s the one shown at the beginning of our PicEngrave Pro 5 instructions PDF.
Without us test cutting 2D with the 2W, I can’t even estimate depth of cut or engraving time. Size of the engraving would be a factor in the engraving time also.
I would test it with my 2W engraver, but it does not have an appropriate heat sink for the 2D/3D cutting.
BillBucket offered to test with his 2W LD.
Here is a video of our 3W 3D engraving and you can see how slow it is running. The engraving was 3.43" (87.12mm) X 5.15" (130.81mm) It took 3 hours 41 minutes to engrave and it cut .125" (3.175mm) total depth in Poplar. It helps to blow the charred wood out with an air assist also
The laser slows to 40.5IPM at full power to cut the black areas in the image and speeds up to 90IPM at zero power in the white areas. The gray text ran at 78.4IPM at 1/4 power to just burn the surface without any cutting into the wood.
The total depth of cut in the black areas is .04" (1mm). The engraving size is 7.56" X 5.25" and it took a total time of 1 hour 49 minutes to engrave. A 2W LD will take considerably more time to engrave. Approximately 3 times longer?
