• Which plastic should I use?

    There are two kinds of filament material can be used for YAYA 3D Pen, ABS and PLA. They are both great while each has its own characteristics. For example, ABS is with more hardness and PLA is more sticky on glass and metal. So each kind of plastic is good for different purpose. We will now compare them in more details.

Compared items ABS PLA
Concise Conclusion ABS is outstanding for making flexible objects with easier modeling effort up in the air(for example to make building and architecture). Featured with its high stickiness property, ABS is also applied to draw on flat paper surface with template. PLA is one kind of great material to make subtle gadget like jewelry and objects with acute angles. Because it sticks well on slippery surface, it is more often used for decoration purpose(for example to add your fancy strokes on vase or mug).
Brief Introduction ABS is one of the most common use and non-toxic plastic in the world, for example, mouse, keyboard, calculator, Tablet PC and many others. It solidifies faster than PLA when it comes out from pen tip. So it’s a good choice for modeling up in the air. PLA is also popular because it is made of eco-friendly cereal powder, non-toxic as well. It’s softer and more sticky when it’s heated in the pen chamber and then extruded from pen nozzle. Whereas after it cools down, it becomes a little more crispy than ABS.
If you want to draw or model better solid objects:
If you want to draw or create objects with shape and continuous angles:
If you like your artwork more bendable:
If you would like to draw on paper or cardboard and then peel it off:
If you would like to draw on glass or metal:
If you want your masterpiece to be more sticky on wall or elsewhere:
If you want to put or use your art in a higher temperature environment:
Is it good to make food container like cookie plate, fruit bowl?
If you want to make semi-transparent works:
Is fluorescent material available?
* We suggest new user to start with ABS at the first beginning to practice and gain confidence to draw and create amazing art. When user have more experience of modeling, heading to PLA will also find more fun and interesting.

What is it made from? Fossil-oil processed Cereal powder processed
Any Smell? No specific smell at indoor temperature. It gives off just a little bit plastic smell when it’s heated while it’s not noxious or allergic to human body. No specific smell at indoor temperature. It gives off just a little bit plant smell(for example corn) when it’s heated. Environmental and no harm to health.
Hardness Harder when it’s heated and is able to undertake more pressure when cools down. Softer when it’s heated and is a little bit crispy when cools down.
Contraction A little bit contraction but no effect for use. Less contraction, suitable for large size project.
Heated temperature for use 200-240℃(392-464℉) 180-220℃(356-428℉)
Stickiness Sticks well on paper, cardboard, plywood and other rough surface. And it’s easy to peel off. Sticks well on smooth surface like glass, ceramics and metal.
How does it look? Glossy Semi-transparent
Inoxidizability Color fades after a long period of direct exposure under strong sunlight. Better oxidation resistant property and anti-fungal. Color fades after a long period of direct exposure under strong sunlight. Easily corrodes in dark and humid environment and less anti-fungal.
Degradability Degradable by nature but needs a really long time. Recyclable for industrial use. Biodegradable, also very slowly. Recyclable for fertilizer.
