Always needing to stretch your budget and looking for ways to cut back? Even though it may seem like a good idea to cut back and buy cheap 3d printer filament – STOP – imagine this to be the blood of your printer – something you don’t want to clog up!!

Our teacher tip of the week: Don’t be tempted with cheap filament replacements – don’t be fooled by their low prices and false properties.

Picture this, you’re pupils have spent the entire term sketching, creating CAD models and are finally ready to 3d print – your final lesson is creeping to an end – so you decide to set the printer for an over-night print! With a spring to your step, a smile on your face, you’re excited to see what’s been printed – unfortunately nothing! the nozzle has clogged and the printer is damaged! what do you do? how do you tell the pupils? how do you tell the head?

To prevent your nozzle clogging and potentially seriously damaging your 3d printer, our tip is to buy high quality filament and calibrate your printer properly for the best results. Best place to start is by speaking with your printer manufacturer and possibly buying in bulk – don’t forget to store them in a dry place.

Filament buying checklist:

  • Only buy filament from a trusted supplier with 3d printing experience
  • Only buy filament that is properly packaged
  • Take time to ask questions about the properties and usability issues

In addition to your nozzle clogging, cheap filament can also damage your build plates – something we’ve also experienced and doesn’t matter how much hot water and elbow grease you’ve got – it just doesn’t budge.
