Guys can anyone tell me in detail which diode is efficient to cut 3mm MDF sheet and how many passes will take to cut.

... could be done with a blue (445nm) 2Watt-diode in 5 to10 passes ...

Thanks Victor.
one more thing what if i use 3W or 5W diode? and what is life of Diode?

It would help to blow compressed air in the cut. Otherwise cut 4-10 don't do much.

IMHO it's more about dot size than laser power. So better spend money for a small spot LD and a good lens.

Thank you I appreciate that but i have seen online machines they are not using compressed air.

... the 3.5Watt-diode has a slightly bigger spot diameter but nearly the same energy density, so it would be slightly better for cutting (for the bigger/thicker cut with easier fume extraction), but not much better for engraving.

The 6Watt-Diode has a much bigger emitter, so the beam and resulting focus is even bigger and more "oval distorted" -- so in spite of even higher power, it won't be better ...

you would need something like 5.6W or 8W laser to do it quickly... but also with 3.5W laser you can do that if there is no rush!
