First, we need to check if the 3d printer is in a state where we can even use the cleaning filament
Please heat up your head & remove whatever filament was inside.
Clean out the pipes that carry the filament around, particularly important if the tubes are long or its a bowden 3d printer.
Check the area on the head where the filament enters to see that there are no existing pieces of broken filament left.
If there are pieces that have been mechanically jammed at the entry point, please follow the instructions on how to clear those FIRST before attempting to go any further.
Once you can confirm the obvious issues are resolved, we can proceed to actually using cleaning filament
You don’t need a lot of cleaning filament – buy one of our small packs here available in 1.75 & 2.85mm
Cleaning filament is designed to stick to grime & residue inside your head, which it sticks to & then purges out.
However, it also allows that to be pulled out.
This process is called a cold extrusion pull.
Please execute this correctly as doing it wrong can DAMAGE any delicate joints or parts in your 3d printer.
Heat the head to a temperature thats slightly hotter than the most recent 3d printing material you had used. For eg, if you had used PLA & you were printing around 210 C, then heat the head tp 240 C.
Do not exceed 280C as the cleaning filament will not work as well at that temperature.
Once the head is heated, slowly push the cleaning filament from the head entry until you can feel a little resistance.
Do not push aggressively, the filament needs to stick to grime, & transport some of the finer particles out the nozzle.
Keep pushing until you see cleaning filament itself coming out the nozzle that looks CLEAR & SHINY like GLASS.
When its nice & clean looking, stop pushing but leave the filament inside. Ensure that the head is clearly holding on to the filament inside & that it has not slipped out.
Now, turn off the extruder heater on the 3d printer – start to see it cool down. Do not leave. Wait for it to reach 120 C
Once at 120C, pull the filament out of the head in a steady stroke. It is common to have resistance, however you should not be putting so much force that the whole unit is lifted off the table as that can break the head parts.
When pulled out, you will see the tip of the filament completely dirty – cut it out & throw away.
Insert the filament back in & extrude a little bit of material. Your 3d printer should be fairly clean now & extrude clean thread of cleaning filament with no impurities stuck to it.
You can repeat this process any number of times, however usually, if 2 pulls have not helped, then you might need to change your nozzle, teflon liners, or other throat columns inside the head. This is common wear & tear especially if you print with filled filaments like Carbon Fibre & Metals.
Solid company to deal with. I have ordered filament multiple times from this company. I have also been advised on better filament options than what I ordered, which worked out really well. Will continue to shop here!

Good prices, fast shipping, excellent communication and when there was a hiccup with my order it was sorted super fast and to my full satisfaction. Can recommend.
Great service from these guys. On my most recent order there was a stellar turnaround of only 24 hours between initial stock query and the filament being in my printer.
Shipping and packaging was excellent and best in market pricing. I had an issue with a misunderstanding about the particular properties of the resin I purchased but Zubbin responded quickly and helped me resolve the issue. Perfect customer service, they have gained a loyal customer.
These guys are awesome. I used to buy my filament from overseas for my projects and needed something in a hurry and went looking for something local. I'm so glad I did. Not only are the prices as good or better than what I was getting overseas and even more of a deal when considering the pricing I was paying for shipping their turn around each time has been next day. Great range of in stock filaments, good prices, super fast turn around and excellent customer service.
This is a fantastic business selling reliable machines at a great price point. What I am impressed with the most is that the owner is always willing to help if I have a problem his insight and knowledge he is so willing to share is always on point and allows me to solve the problem I am trying to resolve.
I look forward to doing more business with them.
Sent them an email explaining what I was trying to achieve and asked for their advice. They responded promptly and recommend a basic 3d printer which turned out absolutely fit for purpose. Ordered online and with good communication i had printer within days. Will definitely return when I upgrade. This printing stuff is very addictive.
Very good, speedy shipping, good quality filament
