Deep engraving brass, 0.5mm deep, 30W fiber laser marking machine. Many friends would like to purchase the first laser as a hobby, do some DIY gifts or declarations, and a lot of our customers began their laser journey as the same way. Gradually, they found lasers able to bring profit to them, doing customized gifts, dog tags, jewelry, firearms and logo printing...... As the suggestion, as a hobby, an used fiber laser or cheap Co2 laser is fine, about 200-1000USD. Starting your business, buy a fiber laser, more than 2000USD or Co2 laser, based on power, more than 1000USD. #laserengraving #co2laser #fiberlaser #laseretching #laserengraving #metaletching #fiberlasermarking (在 Jinan) https://www.instagram.com/p/BsKpFHhAocP/?utm_source=ig_tumblr_share&igshid=evdv4yspz1i4
