Filaments are the building blocks of Fused Deposition Modeling (FDM), a popular 3D printing technology. These thermoplastic filaments are heated and extruded through a nozzle to create layers, shaping a 3D printed object. FDM printing offers a diverse range of filaments, each with distinct properties tailored for various applications.

Dimensional Accuracy

The dimensional accuracy of Fused Deposition Modeling (FDM) 3D printers can vary based on several factors

Typically, the achievable dimensional accuracy for FDM printing lies in the range of 100 to 300 microns (0.1mm to 0.3mm) or sometimes even better with advanced settings and high-quality printers. However, this accuracy is not just dependent on the3D printer alone; several factors influence the final dimensional precision of FDM-printed parts:

Layer Height: Thinner layers contribute to higher precision. Lower layer heights, such as 50 microns (0.05mm) or less, generally improve the print quality and dimensional accuracy.

Nozzle Size: Smaller nozzle diameters can provide finer details and higher precision. Nozzles typically range from 0.2mm to 0.8mm, with smaller nozzles being more precise

Post-Processing and Shrinkage: Some materials might undergo minimal warping or shrinking after printing, affecting the final dimensions of the part.

Material Properties: Different filaments have varying thermal properties and shrinkage rates. This can impact dimensional accuracy, as some materials shrink more than others as they cool.

Print Settings: Printing at optimal temperatures, adjusting cooling settings, and ensuring proper adhesion to the print bed can affect the accuracy of the final print.

Geometry and Design: Certain designs and geometries can affect dimensional accuracy. Overhangs, bridges, and sharp corners may not print as accurately due to the limitations of the printing process.

Printer Quality and Calibration: The quality and accuracy of the 3D printer play a significant role. Well-calibrated printers with robust construction and precise movements tend to produce more accurate prints.

PLA (Polylactic Acid): PA12 (Nylon 12) with glass bead reinforcement.
ABS (Acrylonitrile Butadiene Styrene): ABS is a durable and impact-resistant filament. It has higher temperature resistance compared to PLA and is commonly used for functional parts, prototypes, or parts that require higher toughness. ABS requires a heated bed for printing and is known to produce some fumes during printing, so ventilation is recommended.
PETG (Polyethylene Terephthalate Glycol): PETG is a durable and easy-to-use filament that combines the strength ofmaterials like ABS with the ease of printing associated with PLA. It offersgood chemical resistance and is commonly used for mechanical parts, containers,and transparent prints.
TPU (Thermoplastic Polyurethane): TPU is a flexible filament known for its elasticity and resistance toabrasion. It's used for printing objects that need to be flexible or haverubber-like properties, such as phone cases, seals, and footwear prototypes.
Nylon: Nylon filaments are known for their strength, durability, and impactresistance. They are used for applications requiring toughness and resistanceto wear, making them suitable for functional parts and engineeringapplications.
Woodfill, Metal-fill, and Composite Filaments: These filaments combine PLA or other base polymers with materials likewood fibers, metal particles, or carbon fibers. They offer unique aestheticsand properties such as increased strength, conductivity, or a wood-like finish.
ASA (Acrylonitrile Styrene Acrylate): ASA is similar to ABS but offers better UV and weather resistance, making it suitable for outdoor applications. It's used for parts that need to withstand harsh environmental conditions.
PC (Polycarbonate): PC is a strong and heat-resistant filament used for parts that require high-temperature resistance, such as mechanical components or parts for engineering applications.
PVA (Polyvinyl Alcohol): PVA is a water-soluble support filament used mainly for dual-extrusion printers to create supports for complex designs. It dissolves in water, making it easier to remove supports from intricate prints without manual intervention.
