3D printing company Bambu Lab has ordered a recall on its latest product, the A1. The company released a blog post stating that some of its A1 machines could have damaged cables that connect the heat bed to the main body of the printer. This damage could be enough to cause a fire, and in one case discussed on the Bambu Forum, it caused burns to the machine as well as causing a power cut in a user’s home.
On the blog post, Bambu Lab identified several ways this issue could occur:
We should have designed the strain relief (SR) better to protect the cable from any damage. Our investigation has identified several factors that may cause this damage:
Rough handling during transportation, like dropping the package in certain directions so that the root of the cable is impacted.
During installation, if the base is vertically placed on the table with the cable side at the bottom, all the weight of the printer will be concentrated on the root of the cables and cause damage.
After the installation, the cable’s root on the printer base is impacted by external force by accident.
