We purchased in good faith a Creality Sermoon D3 3D printer and have had absolutely no support for acquiring replacement parts or even troubleshooting advice. We are thoroughly convinced that this Chinese company does not manufacture anything but a mechanism to steal money from unsuspecting customers. This may, and apparently does, apply to all of the products carrying the Creality brand. Do not purchase any Creality products since the outcome appears to follow all of their products.
