Dear All,

I’m tempted in buying 50W fiber laser engraving machine and would like to hear some thoughts about them. I’ve particularly interested on Chinese table top, non closure with JPT LP E-50W laser emitter and around $5000 price range. I’ve watched few review videos from YT and they seem to get mostly positive feedback. Are these generally how long lasting devices? Also I’m concerned about the safety and have few doubts. I’m not sure is it even allowed to sell any non enclosed laser engravers/markers in EU. With the enclosure it would be easier to extract the fumes. How bad are the fumes when engraving AL, ST/ST or some plastics which can be engraved by fiber laser or is it the same than welding them? PVC at least is big no no. Is it enough to vent the fumes through HEPA filter or must vent them outside? For eyes, is it enough to wear the laser safety goggles?

JPT seem to have frequency range from 1-600kHz. Others ~20-60kHz. Does wider frequency range allow more material variety?

Thank you in advance

I have a 50w jpt open machine w/rotory .
Used for aluminums. Steels and stainless steels.
Also cut cardboard with it. Not supposed to work but it does.

50w is nice for deep engraving. Or for large work areal 10x10”
Otherwise save some bucks and go 20-30. Most people do not need 50w

Chinese lasers are cheap and easy to buy. Software is so so. And expect little to no customer support or warranty. YouTube laser master academy. Alex is a big help over there.

If you got time to F around. Chinese is not a bad route.
If you want any support at all your gonna need a much more $$$ vendor. But the major brands will have your back,

Ventilation is a must your vaporizing or ablading materials into a micro fine dust.
Hepa should be fine. I vent it outside after a filter just to be safe.
As an example the dust from ablading aluminum is as fine as talcum powder.
Vision. They say the shields or glasses are fine. Personally if I have a lot of engraving to do I toss a physical barrier in the way.

Frequency’s. It depends on what you wanna do. 20-80k variations are perfect for metals/engraving.
The jpt 2-600 will open up engraving some plastics. 400-600 let me cut cardboard. 300-400/defocus did a nice aneel on stainless.

Overall very happy. Quality of engraving is great. Speed is great.
Setup/learning curve sucked.
Got maybe 300hours laser on time. No problems at all.
Great for blasting my logo all over everything.

That was .07 deep about 8 hours burn time run on max than 45 percent 45 freq and 1000 mm-s to clean the floors up. Then surface grind the top about .002. They are for a hot stamp die for oil filler caps
