PLA and ABS are the materials of choice for FDM 3D printing and are popular for desktop prototyping. These thermoplastics are malleable when heated and solidify when cooled. The printer utilizes FDM technology to melt PLA and ABS filaments and deposit them in layers to create complex parts. While PETG can also be used, PLA and ABS are still preferred due to their versatility and wide availability. Both have unique properties that make them suitable for different applications in the field of 3D printing.
ABS parts are widely used in SLS 3D printing parts applications due to their strength, durability, and heat resistance. SLS 3D printing can create complex ABS parts with high precision.
In terms of FDM printing, the accuracy of printed components depends on printer calibration and model complexity. However, PLA and ABS are excellent materials for making dimensionally accurate parts, with print details down to 0.8mm and the smallest features down to 1.2mm. To ensure strength and integrity, we recommend a tolerance of 0.5 mm and a wall thickness of 1-2 mm for connecting or interlocking components. In addition, PLA has a lower print temperature than ABS, allowing for easier printing and reduced warping when properly cooled, allowing for sharper corners and finer features.
PLA and ABS have similar strength properties, making them suitable for a variety of prototyping needs. ABS is often favored by designers and engineers for its enhanced flexibility. ABS has higher flexural strength and greater elongation before break and can also be used for functional applications. In contrast, PLA is popular for rapid prototyping when aesthetics take precedence over performance. PLA is a good choice for custom parts with low physical stress, UV radiation and high temperatures, while ABS is better suited for industrial applications requiring durability under strain.
