I'm looking for a 100w tabletop laser welder specifically designed for small-scale, high-end jewelry manufacturing. This machine should be capable of precise and intricate welding to help enhance the quality of my custom pieces. Additionally, I'm interested in possibly adding an affordable 3D printer, CNC milling machine, and a dedicated engraving machine to my workshop. My goal is to modernize my shop and incorporate advanced technologies that can streamline production and improve the overall craftsmanship. If you have options that meet these requirements or can suggest suitable alternatives, I would love to hear more about them. Please provide details on pricing, lead times, and any additional features that may benefit my business.
