Why Choose ABS?
When we tested different ABS filaments in our DunaTech workshop, we noticed something interesting: while PLA dominates in FDM 3D printers, ABS remains the king for functional and heat-resistant parts. Why? Because ABS has unique properties such as:
– **Heat resistance:** Ideal for parts exposed to heat, like brackets or gears.
– **Durability:** In our tests, ABS withstood impacts that would have cracked PLA.
– **Professional finish:** Enables post-processing with acetone for smooth surfaces.
However, ABS has a major drawback: it requires a printer with a heated bed and good temperature control. It also produces toxic fumes, so don’t forget to use an air purifier for workshops, like the ones we discuss in our article on air purifiers.
How to Evaluate ABS Filament Quality
At DunaTech, we tested over 7 brands of ABS filament from AliExpress. Here are the key aspects we learned:
– **Constant diameter:** If the filament varies in diameter (e.g., from 1.75 mm to 1.80 mm), your prints will be a disaster. Use a caliper to measure it before trusting a brand.
– **Material purity:** Some cheap ABS is mixed with other polymers that cause clogs. In our tests, the purest filaments were the most reliable.
– **Vacuum-sealed packaging:** ABS absorbs moisture quickly, leading to bubbles and weak layers. Insist on well-sealed rolls.
– **Recommended temperature:** Compare the manufacturer’s specifications with your printer’s range. In our tests, the best results were achieved between 230°C and 250°C.
Brands We Tested
After a month of intensive testing, the brands that stood out were XYZPrinting and eSUN. Both offered excellent diameter consistency and consistent results.
Common Mistakes When Buying ABS
Here are the most common mistakes we see beginners make:
– **Buying ABS without a heated bed:** If your printer doesn’t have a heated bed, forget about ABS. Your print will lift off before finishing the first layer.
– **Ignoring the smell:** Printing ABS produces toxic fumes. If you don’t have good ventilation or an air purifier, you could be risking your health.
– **Choosing the cheapest option:** In our tests, cheap ABS filaments almost always had clogging issues and poor layer adhesion. Going cheap often ends up costing more.
FAQ
What’s the difference between ABS and PLA?
ABS is more resistant to heat and impacts but requires more demanding printing conditions (heated bed and ventilation). PLA, on the other hand, is easier to print and biodegradable.
What should I do if my ABS lifts off the bed?
Try using an adhesive base like hairspray or Kapton tape. Also, ensure the bed temperature is between 90°C and 110°C.
Is it safe to print ABS at home?
Only if you have good ventilation or an air purifier. ABS fumes contain styrene, which is toxic.
Conclusion
ABS filament is a powerful choice for functional parts, but it requires more attention during the printing process. Make sure to invest in reliable brands and always print in a safe environment. If you have questions about how to dry your filament, check out our guide on the Sovol filament dryer.
