What is the difference between U20 and U20 Plus?

In order to meet the needs of more people, we developed the U20 Plus. The U20 Plus has a larger print size of 40 x 40 x 50cm. It is more suitable for printing architectural models.

Will the U20 Plus 3D printer be unstable when it hits a high point?

We have redesigned the U20 Plus's large size and large size. We use thickened structural members to optimize the overall structure and increase the stability and non-jitter design. Please feel free to use it.

What if there is damage?

We have considered various situations during the design. Both the U20 and U20 Plus are equipped with a nozzle anti-blocking and anti-corruption design. The motherboard has a safety fuse that prevents burnout. If you accidentally broke the nozzle board or other parts due to incorrect operation, you can purchase the parts replacement separately from our website. Our technical support will help you all the way.

Why not extruding enough plastic?

1. Incorrect filament diameter;

2. Increase the extrusion multiplier.

Why there are holes and gaps in the top layers?

1. Not enough top solid layers;

2. Infill percentage is too low;

3. Under extrusion.
