Using a LZR35 laser weld orthodontic appliances is a dream. This affordable benchtop laser is precise and leaves a clean weld everytime. I highly recommend! Adding argon to the mix even makes welding better. This appliance is welded directly on 3D model. No duplicating, soldering or burning. To learn more and get pricing click on this link below:
