Documenting Issues with the Sermoon D3 Pro – Let’s Take Action

I’m reaching out to all Sermoon D3 Pro owners to document the problems you’ve experienced with this machine and the solutions (if any) that Creality Support has offered. It’s clear that many of us are facing repeated issues with defective parts, poor quality control, and a lack of proper support from Creality. This situation is unacceptable, and something needs to change.

Here’s what I’m asking:

  1. List the problems you’ve encountered (e.g., defective hotends, calibration errors, LAN printing issues, etc.).
  2. Share the responses or solutions provided by Creality Support (if they’ve offered any).
  3. Mention if your issue was resolved or remains ongoing.

The goal here is to compile a record of these problems to determine if there is a case to be made against Creality for failing to provide functional products or adequate support. Many of us have invested significant time and money into this machine, only to encounter constant frustration.

If we can show a pattern of widespread defects and inadequate support, we may have grounds for action under consumer protection laws. Filing complaints with the Federal Trade Commission (FTC) and the Better Business Bureau (BBB) is a good first step to hold Creality accountable. Additionally, depending on the scale of these issues, consulting a lawyer about a potential class-action lawsuit may be worth considering.

This machine was marketed as professional-grade, but for many of us, it’s been anything but that. If you’ve had a positive experience with the Sermoon D3 Pro, feel free to share that as well—though from what I’ve seen so far, such stories are rare.

Let’s work together to ensure our voices are heard and that Creality takes responsibility for these ongoing issues.

Looking forward to hearing your experiences.

The printer was delivered to us with absolutely no data, no operation manual - nothing that even described it as a 3D printer. From there, it has been a nightmare. I’m not sure where to start to list grievances with this machine - the fact that parts are not available is the main concern. Lets face it, many of the parts on these machines should be considered consumables so should have been supplied with a new machine. I have written here on this forum some of the avenues that we have taken to keep the machine working. I am in the process right now making die molds and fixtures to cast the silicon socks for the hot end since they are NOT available. There have been successes with the machine but as with anything as intricate as it is, there are going to be repairs required. To be honest about it knowing what a pursuit it will be to go after Creality, I’m just about ready to take a 10 lb. sledge hammer to it and take up straightening nails for a hobby… To get back to seriousness, I’ll put together a synapses of the difficulties we have encountered with the machine. We must endeavor to persevere.

The amount of support on this machine is incredible… there isn’t even replacement parts for it. the heat sink screws broke and trying to hunt a new one down seems impossible. very sad to see how poorly they supported this machine.
