Wanhao Duplicator i3 Plus manufacturing defect hazard.


Printers Affected:
Wanhao Duplicator i3 Plus sold before September 19th, 2016.
The Duplicator i3 V1, Duplicator i3 V2, Duplicator i3 V2.1 are not affected, but we still recommend to ensure your printer is properly insulated.


Safety Notice:
Wanhao China has announced a manufacturing defect that could pose a potential electrical and/or fire hazard. The heated build plate’s leveling springs have sharp edges which have the potential to cut through the solder mask of the heated platform and make contact with the metal on the heated bed. This contact has the potential to cause a short in certain positions where the Y-axis mounting screw can rub against grounded parts of the printer, temporarily grounding the bed.  


What to Do:
The manufacturer, Wanhao China, has addressed the issue by preparing a simple solution to resolve this. It is advised to not operate your i3 Plus until you have performed this solution. We are distributing non-conductive insulated bushings to all Duplicator i3 Plus owners that could potentially be affected by this notice who purchased their printer through Ultimate 3D Printing Store ( These bushings are FREE for all Ultimate 3D Printing Store customers.
