Some 3D printing problems and what worked for us.
3D printing takes time and effort. The print might not be the best one in the first try but that's okay :) . It took us weeks to get a decent print of a cube.
Problems | Solutions |
Not extruding during the start | - Increase the skirt width - Check if the nozzle of the extruder is clogged with the filament. |
Print not sticking to the bed | -Increase the bed temperature -Level the bed or change the Z offset -Use tapes for better adhesion -Increase the extruder temperature -Maintain appropriate speed. Initially perform the print in lower speed and gradually increase the speed until you reach the optimum. |
Stringing | -Decrease the temperature -Increase the retraction speed and distance. |
Warping | - Use a heated bed. |
Dimensions of object not accurate | -Calibrate the default axis steps per mm in the firmware itself which is an iterative process. -Level the bed |
Poor Bridging | -Increase bridging speed and increase cooling of the print(fan speed). |
Poor strength of the print | -Increase the number of solid layer -Select appropriate infill pattern and density -Print at higher flow rates |
Over extrusion | -Decrease the flow rate -Decrease the temperature of the extruder |
Under Extrusion | -Increase the flow rate -Increase the temperature of the extruder |
Unexpected stop of the print | -Check if the motors are overheated, and if so, decrease the current. |
Gaps between the printed lines | -Increase the perimeter overlap. -Increase the flow rate. |
Inconsistent Extrusion | -Check for the clogged extruder nozzle and the extruder gear. -Incorrect extrusion width. |
