Stops extruding in middle of a print

Your printer is not extruding anymore in the middle of a print? You must abort the print? This problem can be caused by several separate ones:

Check if the nozzle is clogged

Out of Filament
Slipping extruder gear

Check if the nozzle is clogged

There are two common methods to fix this problem:

Cold Pull

A cold pull works best with slippery, soft materials – like Nylon filament.

Again, heat up your hotend to the working temperature of your Nylon or Polyamide filament, push it through the hotend as far as possible, ideally, until your previous material is cleaned out, which obviously is going to be somewhat hard if your nozzle is completely clogged. Then have the hotend cool down.
What we recommend is to set the hotend to 110, 120°C and just keep on pulling on the filament while the hotend is heating until the filament plops out in one piece. Then cut off the impure end of the filament, fully heat the hotend again and repeat the process until the pulled end of your filament comes out clean and you’ve restored good flow through the nozzle. Usually, two or three passes should be enough.

Tools needed:

Nylon Filament about 1m (about 3 feet).

Needle or wire method

For this method, you need an acupuncture or hypodermic needle, so that you can try to remove the blockage. Obviously, you’ll need a needle or wire that is small enough to fit into your nozzle bore, typically 0.4 mm.
We don’t recommend using a drill bit instead, because they break more easily than solid needles and worst of all, can permanently damage the nozzle if you are not careful.
Preheat the nozzle to your regular printing temperature for each material and start poking with the needle. Be careful not to burn yourself. The goal is to break the blockage so that it slips through the nozzle. The next time you push filament through the blockage will slip through the nozzle together with the filament.
You might have to go through the cycle a few times and push through a bit of filament by hand to check if you have managed to break up the blockage sufficiently. If this method does not work for you try the cold pull method.

Tools needed:

Needle or wire which is thinner than the diameter of your nozzle.
Nozzle 0.4 mm / needle 0.3 mm or 0.35 mm

Out of Filament

Before you start printing, you always have to check if you have still enough filament on your reel.

Description

PLA Filament 1,75 & 2,85mm

PLA (Polylactic acid) is the universal material for all 3D printer. It is easy to print on virtually any 3D printer and by far the most popular in the consumer market for FDM termoplastics. PLA can be printed at low temperatures and with PrintaFix or PrintaStick there is no need for a heated printbed to prevent warping. It has a good interlayer adhesion and low shrinkage and a slight shine to its appearance when the print is done. We recommend it for all decorative elements, prototypes for haptics or test prints.

PLA is plant based and therefor biodegradable. This also means that is not the strongest material when it comes to stiffness, heat resistance or mechanical properties. Nethertheless for its recommended purposes it does the trick. PrintaMent PLA is available in a wide range of colours to satisfy every need.

Why high quality filament matters

AprintaPro filaments are produced 100% in Europe. We know our raw material suppliers and can keep a close eye on the quality we get. Cheaper filament manufacturers often don’t care and then small particles contaminate the filament. These particles will then either be visible in your 3D print or worse clog your nozzle. We only use high quality raw materials for our PLA and colouring pigments so your prints won’t dull during the print or after you put your 3D print on display. We set ourselfs high standards and only accept minimal tolerances in the filament diameter.

Slipping extruder gear

All FDM 3D printers use a small drive gear which grabs the filament and presses it against a bearing or another drive gear. This drive gear has sharp teeth, that allow it to grip the filament. If the filament is unable to move, the drive gear keeps spinning and it can grind away enough plastic from the filament so that there is nothing left for the gear teeth to grab on to.

If this happens on your printer, you will usually see lots of small plastic chippings from the filament that have been shredded away. You may also notice that the extruder motor is spinning, but the filament is not being pushed in the hot end.

To solve this problem, you can try:

  • to increase the nozzle temperature by 5-10 degrees so that the plastic flows easier.
  • to change the printing speed, if the extruder tries to push the filament faster trough the nozzle than the hot end can melt it. Reduce it by 30% to see if the problem is resolved.

If the extruder slipped, make sure that the drive gear of the extruder is clean, because the plastic shreds can fill in the teeth of the drive gear. If this happens it is more likely that the drive gear slips again.
