Fused Deposition Modeling (FDM) is a 3D printing technology that uses a continuous filament of a thermoplastic material. The printer melts the material and extrudes it through a nozzle, laying it down in layers to build up a 3D object. The object is created by following a digital design file, which is sliced into thin layers and fed to the printer. The printer moves the nozzle back and forth across the build platform, depositing the melted material in the desired shape. The material solidifies quickly, allowing the next layer to be laid on top. This process is repeated until the entire object is built. FDM is a widely used technology for creating prototypes, manufacturing tools, and producing end-use parts.

FDM printing process

Here is a general overview of the FDM printing process:

1. Create a digital design of the object you want to print using computer-aided design (CAD) software.
2. Export the design as a .STL file, which stands for STereoLithography. This file format represents the surface geometry of the object using triangular facets.
3. Use slicing software to convert the .STL file into a series of thin layers that the printer can understand. The slicing software also generates the necessary G-code, which is a set of instructions that tells the printer how to move the nozzle and how much material to extrude.
4. Load the filament into the printer. FDM printers typically use spools of thermoplastic filament, such as ABS (Acrylonitrile Butadiene Styrene) or PLA (Polylactic Acid).
5. Set up the build platform and prepare the printer. This may include leveling the platform, installing the build plate, and preheating the nozzle.
6. Start the print job. The printer will read the G-code and begin to move the nozzle back and forth across the build platform, depositing the melted filament in the desired shape. The material will solidify as it cools, allowing the next layer to be laid on top.
7. Monitor the print progress and make any necessary adjustments. Depending on the size and complexity of the object, the print job may take several hours or even days to complete.
8. Once the print is finished, remove the object from the build platform and clean off any excess material. The object may also need to be post-processed, such as sanding or painting, to achieve the desired finish.

Features of FDM printers

Here are some common features of FDM printers:

• Extruders: FDM printers have an extruder that melts the filament and deposits it through a nozzle. The number of extruders can vary, with some printers having a single extruder and others having multiple extruders that can print with different colors or materials simultaneously.
• Build platform: The build platform is where the object is printed. It is typically made of a heat-resistant material, such as glass or aluminum, and is heated to help the material stick to the surface during printing. Some printers have a movable build platform that can be raised or lowered to allow for taller objects to be printed.
• Nozzle: The nozzle is the small opening through which the melted filament is extruded. It is typically made of a heat-resistant material, such as brass or stainless steel, and can be easily replaced if it becomes clogged or damaged. The size of the nozzle determines the width of the extruded material, which in turn affects the resolution of the print.
• Filament: FDM printers use spools of thermoplastic filament as the raw material. The most common types of filament are ABS and PLA, but there are also many other types of filament available, such as PETG (Polyethylene Terephthalate Glycol), PETT (Polyethylene Terephthalate), and TPU (Thermoplastic Polyurethane). The type of filament you choose will depend on the properties you need for your application, such as strength, flexibility, or heat resistance.
• Slicing software: Slicing software is used to convert the digital design file into a series of thin layers that the printer can understand. It also generates the G-code that tells the printer how to move the nozzle and how much material to extrude. There are many different slicing software options available, ranging from simple programs that are easy to use to more advanced programs with a wide range of features and settings.
• Control software: Control software is used to send the G-code to the printer and monitor the print progress. It may also allow you to make adjustments to the print settings, such as the print speed or the temperature of the nozzle. Some printers come with their own control software, while others can be used with a variety of control software options.
