I tried printing from an STL file on the QIDI TECHNOLOGY 3DP-QDA16-01 Dual Extruder Desktop 3D Printer QIDI TECH I. They recommend using the MakerBot software with the Replicator(Dual) profile. The 3D print that I tried is messed up.

The material used is PLA.

Could you help me determine the cause? The following pictures give more details: (All settings which are not shown are Makerware default settings)

Your print isn't cooling fast enough. With small, thin prints like this, PLA needs a fair bit of airflow to solidify before the next layer goes down. Your printer doesn't appear to have a proper print-cooling fan, so I have two suggestions:

  • Print two or even three of the part at the same time, spaced a fair distance apart on the build plate. This will give each of them time to cool.
  • Point a box fan into the front of the printer to get good airflow over the print.
