ABS is used across industries like automotive, appliances, and product design because it performs well under repeated use and heat. In 3D printing, it's a popular choice for parts that need to be mechanically strong, like snap-fit connectors, fixtures, or protective casings. ABS resists common chemicals like oils and cleaning agents.
The surface finish of ABS is matte and well-suited for post-processing. You can sand, drill, or even chemically smooth the print using acetone to create a clean, polished look. However, ABS tends to lose some detail resolution compared to PLA or PET-G—thin features and sharp edges may not come out as crisp. It also has lower layer adhesion than PET-G, which means very fine structures can be more fragile. Just keep in mind it’s not UV-resistant, so it’s not ideal for outdoor use.
Advantages:
- Strong, durable, and slightly flexible
- Work under high temperatures
- Water-resistant and chemically resistant
Disadvantages:
- Lower detail resolution than PLA or PET-G
- Not UV stable – degrades in sunlight
- Weaker layer bonding than PET-G
- Can become brittle in very cold conditions
Why Choose ABS for FDM Printing?
ABS is ideal for:
- Functional prototypes and mechanical parts
- Enclosures or parts exposed to heat
- Jigs and fixtures requiring repeated handling or stress
It’s particularly suitable when you need:
- Long-lasting, strong parts
- Resistance to impact and abrasion
- An easy-to-sand or chemically smoothed finish
