Material Handling, Material Defects, Brittleness 01 Causing blowouts and missing plastic in part buildup.įilament (ABS in this case) contains air bubbles or voids from manufacturing process or from absorbed moisture turning to steam.Įxamine your filament for indications of this manufacturing defect. Popping sound from nozzle like air bubbles under pressure or popcorn popping. Material Handling, Material Contamination 03 This may indicate sub-orifice size foreign particles passing through extruder. Low melting point metal (likely solder) ball noted in ABS (mfr not determined). Print may show indications of intermittent plugging and unplugging of nozzle. Indications of abrasion may be noticed internally in the thermal isolator of the hot end with the lines of abrasion in the direction of filament feed when disassembled. Found in cheap filament (Chinese mfr) noted in PLA from Esun. Particulate inclusions in raw filament as purchased from source. If ooze occurs then stops again after drill bit is removed, a foreign particle may be in melt chamber. Test for condition: (may damage nozzle) while extruder hot, insert a drill bit into the nozzle. Foreign particles may be visible in transparent filaments and may be accompanied by gas bubbles. After the extruder hot section has been disassembled and cleaned out, it is rare to find the particle that was blocking the nozzle. Material Handling, Material Contamination 02Įxtruder jams for no apparent reason. Proper handling of filament to reduce exposure to humidity. ABS is more susceptible to this as it has an affinity for water. Steam blow-outs or bubbles from water absorbed from the humidity in the air into the raw filament during storage prior to printing. Tiny filament width holes on print sides. Material Handling, Material Contamination 01 Intermittent Material Handling or Source Material Contamination In this case, 3mm instead of 1.75mmĬheck your slicer settings to make sure you have the correct filament size Wrong filament diameter selected in the Slicer software. Insufficient material is being extruded by the printer Skeinforge has these settings available to change. Slicer software settings for perimeter widths are slightly too high. Wall thicknesses are coming out too thick, objects have outside dimensions consistently slightly too large and holes are slightly too small. 1.24 Skipping Steps, Signal induced in the endstop.1.22 Skipping Steps, Controller Underpowered.1.21 Skipping Steps, Marlin Configured Incorrectly.1.20 Skipping Steps, Controller Overpowered.1.8 Material Handling, Material Defects, Brittleness 01.1.7 Material Handling, Material Contamination 03.
