FAQs on 3D Printing 101: PLA or ABS? - 2015 Video Lecture - What is 3D Printing: Basic Knowledge - IT & Software

1. What is PLA and ABS?
Ans. PLA and ABS are types of materials used in 3D printing. PLA stands for polylactic acid and is a biodegradable and environmentally friendly plastic. ABS stands for acrylonitrile butadiene styrene and is a durable and impact-resistant plastic.
2. Which material, PLA or ABS, is better for 3D printing?
Ans. The choice between PLA and ABS depends on the specific requirements of the 3D printing project. PLA is easier to work with, has a lower melting point, and produces less odor when printing. It is also more brittle and may not be suitable for applications that require high durability. ABS, on the other hand, is stronger and more flexible, making it ideal for functional prototypes and parts that need to withstand greater stress.
3. Can PLA and ABS be used interchangeably in 3D printing?
Ans. PLA and ABS have different properties, so they cannot be used interchangeably in all cases. PLA requires a lower printing temperature and does not require a heated bed, while ABS requires higher temperatures and a heated bed to prevent warping. Additionally, PLA and ABS have different levels of adhesion to build surfaces, so adjustments may be needed for successful printing with each material.
4. Are PLA and ABS safe to use in 3D printing?
Ans. Both PLA and ABS are generally considered safe for 3D printing. PLA is made from renewable resources and is biodegradable, making it a more environmentally friendly option. ABS, however, can release fumes that may be irritating or harmful if inhaled in large quantities. It is important to use 3D printers in well-ventilated areas or use proper filtration systems when working with ABS.
5. Can PLA and ABS be combined in a single 3D print?
Ans. PLA and ABS can be combined in a single 3D print using a technique called "dual extrusion." This involves using a 3D printer with multiple extruders, each loaded with a different material. Dual extrusion allows for the creation of multi-color or multi-material prints, but it requires a printer capable of handling multiple filaments and may require additional software setup and calibration.
