Choosing ABS filament compared to PLA filament will bring some different printing effects and characteristics, especially when printing detailed models such as toy spiders. Here are some of the differences that may come with choosing an ABS filament:

Strength and wear resistance:
ABS is stronger and more wear-resistant than PLA. This means that printed toy spiders are likely to be more durable and less likely to deform or wear out.
Heat resistance:
ABS material has a high heat resistance, in contrast, PLA will soften at high temperatures. This means that toy spiders printed using ABS materials can better resist high temperature environments.
Printing temperature and environmental requirements:
ABS materials require a higher printing temperature, but also need better ventilation, because ABS printing will release some volatile organic compounds. Therefore, it is necessary to print ABS materials in a well-ventilated environment.
Shrinkage rate:
The shrinkage rate of ABS is higher than that of PLA. This means that when printing large models, there may be more shrinkage problems, and special printing Settings are required to reduce the impact of shrinkage on the model.
Surface smoothness:
ABS may print out a smooth surface, but usually not as smooth as PLA. This may affect the clarity and texture of the details.
To sum up, the choice of ABS material may produce a stronger and more heat-resistant effect than PLA material, but special attention needs to be paid to printing temperature and environmental requirements during the printing process, as well as dealing with possible shrinkage problems. Depending on your specific requirements for toy spider models, you can balance the above factors to choose the printing material that best suits your needs.
