If you start a 3d Print & nothing is coming out, there are a few things you can check:
Stop the 3d print. Ensure the temperature you had set it to was adequate for the material
Heat the 3d printer to the temperature of the material
Remove the existing plastic filament out of the 3d printer
Check to see if it is obvious that the filament has broken & not all of it has come out of the tube
Check to see if the end that has come out is very badly bulged. Regardless of how bulged it is, cut some of the end off. Ensure the filament has a nice clean round appearance before it is ready to insert again.
If the end coming out has a ring followed by a bulged section of the filament that is significantly larger, then it is likely you are getting ‘heat creep’. Heat Creep means the heat from the hot end is making its way all the way to top where the filament should be solid, & not yet fluid. Heat creep is most commonly found with badly designed heads on entry level 3d printers, however, it can be if you use fundamentally wrong settings.
If its not settings related, the most common thing is to replace the nozzle. Yes you can clean them, but it is often not worth the effort as nozzles are quite cheap now a days.
Once the nozzle is clean, you can consider replacing parts higher up the chain. The most common of these is called something like a ‘throat’, or a liner, or heat brake. This is the part that essentially should have solid filament in it as it is led to the hot end block where the heaters sit & nozzle mounts onto.
Try extruding filament first by just pushing it with your hand. If it doesnt work, the 3d print is definitely not going to work. This is important because it also helps identify if the issue is with the heating & passage, or its the motor that is unable to push the filament down.
If you have established all of these settings are ok, now might be a good time to contact 3D Printing Services :)

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.
