FDM 3D Printing Technology

FDM (Fused Deposition Modeling) Plastic Filament Printers

FDM printers employ thermoplastic filaments, which are plastic materials that melt upon heating. They can be molded when hot and solidify upon cooling. The filament is fed into the printer’s extruder assembly heating chamber, where it is heated to its melting point and then extruded through a metal nozzle. As the extruder assembly moves, it follows a path that has been programmed into a 3D model file, creating the printed model layer by layer.

FDM (Fused Deposition Modeling) printers utilize a diverse array of materials to create three-dimensional objects. The choice of material greatly influences the properties and applications of the final printed object. Key materials used in FDM printing include:

Materials Used in FDM (Fused Deposition Modeling) Printers

PLA (Polylactic Acid) ABS (Acrylonitrile Butadiene Styrene) PETG (Polyethylene Terephthalate Glycol-modified) TPU (Thermoplastic Polyurethane) Nylon ASA (Acrylonitrile Styrene Acrylate) PC (Polycarbonate)

A biodegradable thermoplastic made from renewable resources like corn starch. PLA is popular for its ease of use, low warping, and vibrant color options, making it ideal for beginners and applications where aesthetic appeal is important.

Known for its strength, durability, and higher temperature resistance compared to PLA. ABS is widely used in functional prototypes and objects that require toughness, though it can emit odors during printing.

Combines the ease of printing of PLA with the strength and durability of ABS. PETG is also resistant to moisture and chemicals, making it suitable for practical applications.

A flexible and durable material that can be stretched and bent, ideal for creating parts like phone cases, flexible joints, and seals.

Offers high strength and flexibility, making it suitable for parts that need to withstand wear and tear. Nylon is also resistant to chemicals and high temperatures.

Similar to ABS but with improved UV resistance, making it suitable for outdoor applications where exposure to sunlight is a concern.

Known for its high strength and temperature resistance, PC is used in demanding applications, such as engineering and industrial components.
