Desktop fiber laser marking machine are optimally suited for metal marking by way of annealing, for metal engraving, and for high-contrast plastic markings. Fiber lasers are generally maintenance-free and feature a long service life of at least 100,000 laser hours. Direct material laser marking (laser engraving, etching, annealing, etc.) is a fast and effective way to permanently mark parts, products and materials. A laser beam interacts with the material to create lines, numbers, a logo or any desired image for easy tracking, precision control and quality tracing.
A substrate layerPrecise positioning of the work piece for laser cutting or engraving is necessary in some cases.It is important to define the cutting or engraving boundaries for Endurance DIY and Endurance Makeblock machines.We recommend a mesh substrate layer. With its help it is easy to accurately position the work piece on the work table.When you work with Endurance DIY / Endurance MakeBlock lasers and engravers use an aluminum sheet to cover the work table.This will protect you from fire and protect the work table surface from damage. The painted aluminum sheet may be used for laser focusing. But you need to remember that focusing the laser beam on the work table surface you will need to correct the focus according to the thickness of your work piece. Price: 19.95$. The actuatorTo optimize the laser beam focusing you can also use for it a black metal plate and focus the laser manually. Do it wearing safety goggles.
If you have a good vision you will easily see when the laser point becomes the smallest. This is your optimal focus.However, there’s another method. Install an actuator on your laser. Almost all machines and coordinate tables enable to controll the third (Z) axe. In this case you can focus the laser in the program by means of lifting or lowering it. Using the actuator you can do it easily and accurately enough especially, when you engrave work pieces of variable thickness.In addition, knowing the height of the work piece, you can set the focus, even without using the visual method. It is enough to calculate the necessary number of steps.
Usually one step is 0.1 mm. Price: 49.95$. Laser fastening / mount / holderSecure laser fastening is, firstly, a guarantee of your safety and, secondly, of a good quality cutting and engraving.A poorly secured laser creates a vibration, which results in a poor quality cutting or engraving.If the laser mount breaks during the operation, it is fraught with tragic consequences.That’s why Endurance pays special attention to the laser fastening. The laser mount is universal and suitable for almost any 3D printer or CNC machine.Additionally, Endurance offers fasteners for coordinate tables and engravers of the Makeblock and DIY like. Price: 29.95$. Ferric chloride for etching and electrolysisIf you need a deep engraving on metal: steel, aluminum and such like materials, use electrolysis. To begin with, paint the work piece or cover it with a special film (an adhesive tape, for instance), then draw a desired image using your laser.

The laser will burn the film, exposing the parts of the metal surface to be etched.Then dip the work piece into a citric acid solution or a solution of kitchen salt (NaCl) or ferric chloride FeCl2 / FeCl 3 and let the electric current of 12V 2-3A go through the solution.The reaction of chemical etching will take place. Price: 39.95$.
