drawing: The material left in the nozzle from the last print cools and hardens.<\/li>\n<li>Material selection error: Some materials are not suitable for 3D printing and can cause blockages.<\/li>\n<li>Nozzle dirt: Dust or debris accumulated on the nozzle may cause blockage.<\/li>\n<li>Incorrect extrusion temperature: The optimal extrusion temperature depends on the type of filament you use and the nozzle size and design of the 3D printer.<\/li>\n<li>Improper calibration of the extruder: If the extruder is not accurately calibrated, the filaments may come out faster or slower than expected, which may cause blockages.<\/li>\n<li>The nozzle diameter is too small: The nozzle diameter of the 3D printer should match the size of the filament you are using, otherwise, it may cause blockage due to low flow rate.<\/li>\n<\/ul>\n<p><strong>Processing method:<\/strong><\/p>\n<ul>\n<li>Manually push the wire into the extruder: Try manually pushing the wire into the extruder. Manually increase the nozzle temperature in the machine control, set the temperature to 230 degrees, and then select Move Shaft &#8211; Move 1mm &#8211; Extruder in the preparation to extrude a small amount of plastic.<\/li>\n<li>Reinstall the wire: If the wire is still not moved, the next thing you need to do is to remove it. Make sure the extruder temperature is correct, then remove the consumables from the extruder. After the wire is removed, use scissors to cut off the melted or damaged parts of the wire. Then reinstall the wire.<\/li>\n<li>Clean the nozzle: Use a wire brush, which has greater friction, to easily remove charred material from the metal nozzle and heating block surface.<\/li>\n<\/ul>\n<h3><span class=\"ez-toc-section\" id=\"Stereolithography_SLA\"><\/span>Stereolithography (SLA)<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><strong>Possible reasons:<\/strong><\/p>\n<ul>\n<li>The resin is cured in a photocurable nozzle (Vat).<\/li>\n<li>The photosensitive material of the light-cured nozzle is aging or damaged.<\/li>\n<\/ul>\n<p><strong>Solution:<\/strong><\/p>\n<ul>\n<li>Regularly replace the resin in the resin tank to avoid residual cured resin.<\/li>\n<li>Clean the light-cured nozzle and remove the cured resin.<\/li>\n<li>Check the photosensitive material and replace it if necessary.<\/li>\n<\/ul>\n<h3><span class=\"ez-toc-section\" id=\"Digital_Light_Processing_DLP\"><\/span>Digital Light Processing (DLP)<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><strong>Possible reasons:<\/strong><\/p>\n<ul>\n<li>The resin solidifies on the projection window.<\/li>\n<li>The optical components of the projector accumulate resin or dirt.<\/li>\n<\/ul>\n<p><strong>Solution:<\/strong><\/p>\n<ul>\n<li>Regularly clean the projection window to avoid resin curing.<\/li>\n<li>Clean the optical components of the projector with a special cleaner.<\/li>\n<\/ul>\n<h3><span class=\"ez-toc-section\" id=\"Selective_Laser_Sintering_SLS\"><\/span>Selective Laser Sintering (SLS)<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><strong>Possible reasons:<\/strong><\/p>\n<ul>\n<li>Powder accumulates near the laser sintering nozzle.<\/li>\n<li>The laser power of the laser sintering nozzle decreases or the focusing is inaccurate.<\/li>\n<\/ul>\n<p><strong>Solution:<\/strong><\/p>\n<ul>\n<li>Regularly clean the powder accumulation near the nozzle.<\/li>\n<li>Check the laser power and focus, and calibrate if necessary.<\/li>\n<\/ul>\n<h3><span class=\"ez-toc-section\" id=\"Powder_Bed_Fusion_PBF\"><\/span>Powder Bed Fusion (PBF)<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><strong>Possible reasons:<\/strong><\/p>\n<ul>\n<li>Powder accumulates near the laser melting nozzle.<\/li>\n<li>The laser power of the laser melting nozzle decreases or the focusing is inaccurate.<\/li>\n<\/ul>\n<p><strong>Solution:<\/strong><\/p>\n<ul>\n<li>Regularly clean the powder accumulation near the nozzle.<\/li>\n<li>Check the laser power and focus, and calibrate if necessary.<\/li>\n<\/ul>\n<h3><span class=\"ez-toc-section\" id=\"General_Solution\"><\/span>General Solution:<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<ul>\n<li>Regular maintenance: Regularly maintain and clean the 3D printer, especially the nozzle part.<\/li>\n<li>Use Recommended Materials: Use print materials recommended by the printer manufacturer to reduce the risk of nozzle clogging.<\/li>\n<li>Proper Storage: Printing materials should be stored properly to avoid moisture and contamination.<\/li>\n<li>Step-by-step investigation: If the nozzle is blocked, step by step investigate the possible causes, from simple material replacement to complex hardware inspection.<\/li>\n<li>Check whether the temperature is in place: if the temperature is not a problem, it is still blocked, and the temperature is raised to 240 degrees.<\/li>\n<li>Manually pinch the consumables and push the material: remove the nozzle end guide pipe, press the extruder button, manually pinch the consumables and push the material to see if the nozzle is filament.<\/li>\n<li>Try whether to return: If you can return the material, then after exiting the consumables, wait a few minutes, use the smallest internal hexagonal wrench equipped, and poke it inward from the pneumatic interface end.<\/li>\n<\/ul>\n<h3><span class=\"ez-toc-section\" id=\"Processing_for_Specific_Materials\"><\/span>Processing for Specific Materials<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Using Acetone Solution: In the case of 3D printing using ABS, remove the nozzle from the 3D printer head and place it in acetone for a few hours.
