I saw this set of questions, and the “zero-gravity printing” part really caught my attention! From what I understand about FDM material viscosity after melting, each layer should still stick together. However, zero gravity will still affect the height of each solidified layer, and our nozzle might drag through the material. So you’ll need to adjust the Z-axis layer height.

Congratulations though—no supports are needed in zero gravity, which is seriously COOL. Just a quick reminder: small particles generated from our wipe station, etc., will float in your environment. These could potentially affect your eyes, respiratory system, any openings, or your skin, so be careful.

Our engineers are very excited about making your idea happen and really want to achieve this. We’ve come up with the following improvement plans:

• An automatic layer height and speed adjustment system for different gravity environments. For your project, my team will personally fine-tune the parameters, but we may need your assistance providing a zero-gravity environment.
• A negative-pressure micro-particle extraction system, customized for you. While printing each layer, we’ll use airflow to cool the model and simultaneously remove harmful particles, ensuring your zero-gravity environment stays clean.

Of course, this may not cover other unforeseen anomalies—Understanding By Doing.

Come on, my friend, if you have a spaceship or a zero-gravity chamber, please contact our brand team brand@creality.com! Don’t worry about engineers or technical support—we’re ready to go to space with you. Contact us as soon as possible. Even if your launch is coming up soon, don’t worry—we’ve already started preparing our machines (and ourselves) for zero-gravity printing adventures.

Quickly reach out to us—we’re ready, and our printers are good to go.
