One of the most important parts of using a 3D printer is cleaning it up afterwards. Without this, the printer is at a higher chance of running into problems and breaking down. You should think of it as an old clock, where if one small part is out of place or not running properly, the entire machine is thrown off. So, I’m dedicating this blog post as a how-to for cleaning the 3-D printer between uses.
Cleaning the bed
The printer bed is the metal plate that the printer extrudes plastic onto while running. Proper cleaning after a print is essential for proper adhesion and to prevent warping. There are several different ways to clean the bed. The first is specifically if you used a bonding adhesive like a glue stick to keep the print on the bed. For this you will need some rubbing alcohol (nail polish remover) and cotton swabs or other disposable cloth. All you need to do is dampen the swab or cloth and rub the bed where the glue is until it has all been removed. If your cotton swab or cloth gets too dirty to continue removing the glue, throw it away and get a new swab and keep going. You are done when there is no residue left, if you see streaks of rubbing alcohol on the bed, don’t worry. It should evaporate and disappear after a few seconds.
If you don’t need to remove old glue, then just giving the bed a quick wipe down should remove any accumulated gunk. Just remember not to push too hard onto the bed or you may throw off the calibration and have to re-level it.
A quick cleaning of the extruder after the print is a good way to keep the nozzle from clogging and/or extruding too thin of lines. All you need to clean the exterior is a cleaning pick of some sort. After your print, while the extruder is still hot, take your pick and scrape off any plastic that got stuck to it. While it may seem simple and inconsequential, this is important to remove as it will build up over time and lead to the filament potentially becoming a heaping glob on the nozzle instead of printing onto the bed as it should. Makerbot has also made a video on how to clean the inside of the nozzle that you can watch below, however I don't recommend doing this unless you have some experience with the printer, and even then you only need to do it every once in a while.
To conclude, it is important to clean your 3D printer to keep things running smoothly. Just remember to clean the bed and the outside of the extruder of the printer after every print to keep it running up to par, as well as keep your 3D prints nice and clean and orderly.
