Do you want to discover everything you need to know about FDM 3D printing? At Imprimy, we are here to explain everything about this type of 3D printers.
FDM 3D printing is an accessible, versatile, and cost-effective technology that creates objects by depositing, layer by layer, a melted thermoplastic filament.
What is FDM 3D Printing?
FDM 3D printers are specialized printers that use thermoplastic filaments to create three-dimensional objects.
How FDM Printing Works
FDM 3D printing (Fused Deposition Modeling) works by extruding melted thermoplastic filament, deposited layer by layer. The filament is heated in a moving nozzle that traces the model according to a digital file.
Each layer solidifies as it cools down, gradually forming the final object. This process is valued for its simplicity, affordable cost, and versatility.
The materials used for FDM printing
The main materials used in FDM printing are thermoplastics like PLA, ABS, and PETG. PLA is easy to print and biodegradable, ideal for beginners.
ABS is more durable but requires a heated enclosure. PETG combines strength, flexibility, and ease of printing.
The components of an FDM printer
An FDM printer mainly consists of an extruder, which pushes the filament, and a heated nozzle, which melts it. The print bed, often heated, receives the layers of material.
Motors move the nozzle and the bed along the X, Y, and Z axes. A motherboard controls everything through integrated software.
What are the advantages of FDM 3D printing?
FDM 3D printing’s main advantages are that it is accessible, versatile, and also easy to use.
The accessibility and cost of FDM 3D printing
FDM 3D printing is the most accessible technology on the market. Printers are available starting at just a few hundred euros, with a low filament cost.
It is perfectly suited for individuals, makers, and small businesses. Its quality/price ratio makes it a popular solution for prototyping and custom object creation.
The versatility of the different compatible materials
The materials compatible with FDM printing offer great versatility depending on the needs. PLA is ideal for prototypes, ABS for technical parts, and PETG for moisture-resistant objects.

What tips should be followed to get started with FDM printing?
To get started with FDM 3D printing, you should ensure you choose the right machine, prepare your model properly, and optimize it while avoiding common mistakes.
Choosing the right FDM 3D printer
To choose an FDM 3D printer, you need to consider the print resolution, the build volume size, and the reliability. The user’s experience level also influences the choice: ready-to-use models for beginners or modular machines for experts.
The budget remains a key criterion, as well as the availability of consumables and technical support. Comparing these aspects helps find the printer suited to your needs.
Properly preparing your model for 3D printing
To properly prepare your model for FDM 3D printing, start by checking its integrity and closure in a modeling software. Then, use a slicer to generate the G-code file, adjusting parameters like infill density, print speed, and temperature.
Remember to add support structures if necessary for overhanging parts. Good preparation ensures a precise and flawless print.
Optimizing your 3D print settings
To optimize your FDM 3D prints, adjust the nozzle and bed temperature according to the filament used. Set the print speed for a good balance between quality and speed.
Remember to calibrate bed leveling and retraction to avoid defects like stringing or warping. Testing different parameters helps achieve precise and durable results.
Avoiding Common Mistakes in 3D Printing
To avoid common errors in FDM 3D printing, make sure to have good bed leveling before each print. Avoid too high temperatures that cause blobs or warping.
Also, check the filament quality to prevent extruder jams. Finally, plan supports for overhanging parts to avoid structural defects.
