How to recognize when 3D printer temperature is too low?

The temperature of the nozzle is crucial for the quality and strength of the printed object. If the temperature is too high, the filament may burn, clog the nozzle, or ooze excessively. If the temperature is too low, the filament may not melt properly, resulting in poor adhesion, under-extrusion, or warping.

So how can you tell if your 3D printer temperature is too low? Here are some signs to look out for:

• The filament does not stick to the build plate or to the previous layers. This can cause gaps, holes, or cracks in the printed object.
• The filament curls up or bends at the tip of the nozzle. This can cause stringing, blobs, or zits on the surface of the printed object.
• The filament snaps or breaks easily. This can cause jams, clogs, or extruder skipping.
• The printed object has a rough or matte surface. This can reduce the aesthetic appeal and smoothness of the printed object.

If you notice any of these signs, you may need to increase your 3D printer temperature by a few degrees and try again. You can also use a temperature tower test to find the optimal temperature range for your filament and printer model. A temperature tower is a simple model that prints at different temperatures along its height, allowing you to compare the results and choose the best one.

Different filaments have different melting points and require different temperatures. For example, PLA typically prints well at around 200°C, while ABS needs around 230°C. You should always follow the manufacturer’s recommendations and adjust accordingly based on your printer’s performance and environment.
