3D Printing material PETG, ABS, and PLA.

Posted on Updated on

PETG, ABS, and PLA are three commonly used materials in 3D printing. Here’s a brief overview of each material. PETG is more durable than ABS or PLA. The various brands of 3D printing filaments.

  1. PETG (Polyethylene Terephthalate Glycol-Modified): PETG is a solid, durable material with excellent impact resistance. It has good flexibility and is resistant to chemicals, making it suitable for various applications. PETG is also transparent, allowing for translucent prints. It has a relatively low shrinkage rate during printing, which helps minimize warping. PETG is often used for functional prototypes, mechanical parts, and containers.
  2. ABS (Acrylonitrile Butadiene Styrene): ABS is a popular 3D printing material known for its strength, durability, and heat resistance. It exhibits excellent impact resistance and toughness, making it suitable for functional parts and prototypes that withstand stress or higher temperatures. ABS has a higher melting point than PLA, but it tends to shrink and warp more during printing, so proper bed adhesion and temperature control are essential. ABS is commonly used in automotive parts, electronic enclosures, and consumer products.
  3. PLA (Polylactic Acid): PLA is a biodegradable and environmentally friendly material derived from renewable resources like corn starch or sugarcane. It is easy to print with and generally requires lower printing temperatures than PETG and ABS. PLA is rigid and relatively brittle, making it less suitable for applications that require flexibility or impact resistance. However, it is famous for printing prototypes, artistic models, and objects that don’t require high strength. PLA is available in a wide range of colors and finishes.

When choosing a material for 3D printing, consider the specific requirements of your project, such as strength, flexibility, heat resistance, or environmental impact. Each material has advantages and limitations, so selecting the one that best aligns with your desired outcome is essential.

ABS is a petroleum-based plastic. ABS is non-biodegradable. ABS is a strong and durable material.  Therefore it is used in various products including protective headgear, golf club heads, carrying cases, enclosures for electronic assemblies, kitchen appliances, and toys including Lego bricks.  ABS is soluble in acetone, i.e., nail polish remover.
ABS is extruded at temperatures of 210-250°C. Heating up ABS causes fumes to be released. These fumes are usually tolerable but may cause irritation in people with chemical sensitivities. These fumes include chemicals that are known to be carcinogenic. Therefore, 3D printing using ABS should be performed with caution and in places with adequate ventilation.
