Cleaning a clogged nozzle is very hard at times. This is an easy and cheap method to clean clogged nozzle.

Step 1: Things You Need

1. Acetone (Nail polish remover)

2. Candle or Lighter

3. Needle

4. Aluminium foil

Step 2: Dip the Nozzle in Acetone

The higher the concentration of acetone lesser the time required.

I use nail polish remover because they are cheap and easy to get.

Leave it for 20-30 minutes.

Step 3: Clean the Big End Using Needle

Remove the plastic using a needle.

There will be plastic left over a the tip which cannot be cleaned using needle.

Step 4: Wrap the Nozzle

Wrap the nozzle in Aluminium foil. Leave the top end open so that the fumes can go out.

Step 5: Bring It Near to Flame

Hold the nozzle into the flame for around 5 minutes. Remove foil and check the nozzle

- If there is still plastic heat it again.

- If it is clean then wash the nozzle and remove any leftovers using needle.

Step 6: Thats It..:-)

Hold it near to any light source and check whether it is clean.

modern nail polish removers aren't made from aceton. And if you compare the price to aceton is aceton cheaper (3-5&euro;/l)
<p>Correct! And nail polish removers often have oil in them to prevent drying of delicate ladies hands.</p>
<p>Thanks for this instructable. But, i think that it's ok just for ABS, Acetone has no effect on PLA. </p>
<p>You can use chloroform for pla :)</p>
thanx for the tip.
<p>How do you get the nozzle off? I assume I use an adjustable spanner but I don't want to wreck it doing the wrong thing.</p>
<p>Excellent idea wrapping it in foil, before this I just held them over stove but now with foil they'll look cleaner! :P</p>
<p>I use these, Personally:</p><p>http://www.amazon.com/Printer-Clogged-Extruder-Makerbot-filament/dp/B016O43KKC/ref=sr_1_22?ie=UTF8&amp;qid=1453416225&amp;sr=8-22&amp;keywords=3d+printer+clean</p>
<p>I found a sewing pin that was about 1/3mm, and fit through the nozzle to help clean it. </p><p>Thank you for this.</p>
<p>Just to confirm, tried this with a 0.4 mm nozzle that had PLA clogged in it. Worked for me by attaching the M6 thread of the nozzle onto a nut and holding that with a set of helping hands over a flame for about 5-6 mins. And then every couple of mins I'd slide a piece of steel wire just to see if the PLA has evaporated. PLA burns with a sweet scent so you'll know when it stops burning and fully evaporated. Flush it under cold water and wholla! :) Presto. Key element in this instructible is the aluminum foil. Prevents soot from building up on the nozzle. Great work MRDC! </p>
<p>Though around they do sell acetone in the nail polish remover part of the stores. It's 100% acetone, but oddly it doesn't have the scary warning labels that the acetone sold in the hardware section does.</p>
A steel guitar string will go through the nozzle end.
<p>Fantastic, I completely forgot you could use acetone.</p>
Very good! This is very descriptive and every thing that was in words was in pictures. I have no suggestions for you! Great Job! :P
