1.Q:The printed model is single color, why?

A: The length of the PLA rainbow in each color is constant, and the customer calculates the length or weight of the filaments needed to print the model according to how many colors the customer wants to show when cutting.

2.Q: The color of a printed object is different from the color of the filament itself, why?

A: This is a normal phenomenon. Limited by process and objective chemical changes, some colors of rainbow threads have a coating effect, that is, the outer surface is in one color, and the inner is in another color.

3.Q: Why are my threads getting tangled? How can I solve it?

A: Thread knotting is not caused by disorderly or imperfect winding. When making filament, the filament is wound back and forth (left to right and then right to left). Usually there is no knotting of the thread. A common cause of tangles is that the filament end is not fixed in the holes of the spool. The knotting by overlapping or the changed winding direction leads to a knotting of the filament. Therefore, customers need to attach the thread end to the correct holes of the bobbin.

4.Q: Can PLA be used for tableware printing?

A: Not recommended. Although PLA is a degradable, food-grade raw material, the PLA with toner is not food-grade.

5.Q: The nozzle is clogged with PLA, how can I solve the problem?

A: An inconstant filament diameter, a nozzle temperature that is too low and frequent replacement with other filaments lead to this problem. So clean the nozzle before you start and adjust the temperature to a reasonable level.

6.Q: My prints have problems with web-like threads (stringing). How can I fix the problem?

A: If the temperature is too high, the PLA filament will melt and flow so quickly. Please turn down the temperature to a reasonable level.

The feed parameters are not correct, so adjust the feed length and speed.

7.Q: There is too much melted filament around the nozzle. What should I do?

A: This issue can be traced back to too high temperature, too low print speed, and nozzle diameter mismatch in slice software with extrusion performance.

8.Q: The PLA filament was perfect when I opened the package. After printing intermittently several times, my PLA filament accidentally breaks during printing. Why?

A: Normally, PLA filament does not break by itself during the printing process. However, being a degradable material, PLA becomes more brittle and breaks easily after exposure to moisture, so you should pay attention to moisture protection.

9.Q: The surface of my print is not very smooth and the extruded filament has inconstant diameters. Why is that?

A: The surface of my print is not very smooth and the extruded filament has inconstant diameters. Why is that?

10.Q: Why won't my PLA printed objects stick to the heatbed? How can I solve this?

A: The distance between the nozzle and the bed is too big. Make sure your heatbed is level and clean. Then judge whether the printing temperature and heatbed temperature are too low, and our customers should adjust them to the right range.
