FDM Printer

FDM - Fused Deposition Modeling and is one of the most common 3D techniques in additive manufacturing.

What is FDM printing? How does this technology work?

FDM 3D technology is a revolutionary technology that has changed the manufacturing landscape, enabling the creation of complex and intricate designs with precision and efficiency. Let's describe more about how FDM printer works and the magic behind this fascinating process.

At the heart of FDM technology is a simple but ingenious process that brings digital designs to life layer by layer by melting a plastic wire called a filament. This plastic wire is

How it works:

  1. Digital design : It all starts with a digital 3D model created using computer-aided design (CAD) software. This design serves as the blueprint for the item you want to create.

  2. Printing process : The digital model is then converted into a software called a slicer. The slicer converts your 3D model into a so-called .GCOD file.
    The file is then uploaded to the 3D printer and printing can be started. Then the printer works through these coordinates and builds up the model one layer at a time until it is complete.

    The .GCODE file contains a description with calibration values ​​and coordinates for how the FDM printer should move.

  3. Material selection : FDM printer uses different thermoplastics in the form of a plastic wire of 1.75 or 2.85 mm. The most common FDM printing materials are PLA, ABS, PETG. The materials come wrapped on rolls and are available from 50g to 10KG rolls.

  4. Heating and Extrusion : The FDM printer heats the wire to its melting point within a heated nozzle called an extruder. When melted, the material becomes tough and can be extruded through a fine die in precise patterns.

  5. Layer-by-Layer Deposition : The printer nozzle moves along the X, Y and Z axes according to the sliced ​​layers and deposits molten material on the build platform. As each layer is laid down, it binds to the previous layer and gradually builds up the object.

  6. Cooling and solidification : Once the extruded material is deposited, it cools and solidifies rapidly, retaining its shape and integrity. This process ensures that each layer adheres firmly to the previous one, creating a stable and durable final product.

  7. Support structures (if necessary) : In some cases where the 3D design requires overhangs or complex geometries, the printer can include temporary support structures made of the same material. These supports provide stability during printing and can be easily removed when printing is complete. if you have a printer with dual print heads, you can use a water-soluble support material for best results.

  8. Completion : When all layers are deposited and the object is fully formed, the build platform is lowered and the finished object can be removed from the printer. Depending on the complexity and size of the object, printing can take anything from a few hours to several days.

FDM 3D printing offers outstanding versatility and is widely used in various industries, including aerospace, automotive, healthcare and consumer goods. Its ability to create functional prototypes, custom parts and intricate designs with speed and precision has made it a cornerstone of modern manufacturing.
