For printing small models like toy spiders, the following types of 3D printer filament materials can usually be used:

PLA (polylactic acid) :
PLA is a commonly used 3D printing material suitable for printing small models and toys. It is easy to print, environmentally friendly, non-toxic and has a smooth surface for printing models that require fine detail.
ABS (acrylonitrile-butadiene-styrene) :
ABS is another commonly used 3D printing material with high strength and wear resistance. Ideal for printing toy models that require higher strength and durability.
PETG (Polyethylene terephthalate) :
PETG is a heat-resistant, impact-resistant material that is suitable for printing models that require some strength and durability, while being easy to print.
TPU (Thermoplastic polyurethane) :
TPU is a soft elastic material, suitable for printing toy models that need soft texture or elasticity, such as toy animals.
The materials listed above are more suitable for printing small toy models, with good printing performance and finished product quality. Depending on your specific needs and design requirements, you can choose the right 3D printed filament material for your project.
